In today's era of pursuing high-quality life and efficient work, projectors are no longer exclusive to professional settings. They have quietly entered thousands of households, becoming a powerful assistant for home entertainment and playing a key role in business presentations, education and teaching. Imagine coming home after a busy day, closing the curtains, turning on the projector, and instantly transforming the living room into a private cinema, enjoying the stunning experience of watching movies on a large screen; Or at business meetings, using a projector to clearly present the plan can make communication smoother and more efficient. However, facing the dazzling array of projector products on the market, ranging from a few hundred yuan to tens of thousands of yuan, with various brands, models, and parameters, how should one choose a projector that suits oneself? Don't worry, we will now provide a detailed analysis of the key points to pay attention to when choosing a projector. We will also highlight the attractive advantages of the Paihao projector, helping you make a wise choice easily.

Brightness: Illuminates clear field of view

Brightness is one of the core indicators of a projector, which directly determines the clarity of the projected image under different ambient lighting conditions, just like the "soul" of a projector. A high brightness projector has stronger light resistance, and can project clear and bright images even in environments with sufficient lighting, without the embarrassing situation of "dying in the face of light"; On the contrary, low brightness projectors often result in dim and blurry images in strong light environments, seriously affecting the viewing experience.

At present, the main units for measuring projector brightness are ANSI lumens and CVIA lumens. ANSI lumen is a method developed by the American National Standards Institute to measure the luminous flux of projectors. It measures the brightness of the projected image by taking nine points under certain conditions, and then calculates the average brightness value of the nine points. This standard specifies the "nine point" measurement method, but it strictly requires the size of the projected image, while ignoring the projection distance and possible losses during the projection process. Overall, the calculation is relatively simple and it is currently the mainstream brightness standard internationally. And CVIA lumens is the first brightness standard in China's projection industry, jointly developed by the China Electronic Video Industry Association, Dangbei and other upstream and downstream enterprises. It has stricter testing standards and requirements, stipulating that the color temperature for projector testing should be between 6000K and 18000K, which is more in line with the viewing color temperature of Asians; Require color coordinates to be maintained in the CIEI976 uniform color space, with a color deviation value of Duv ≤ 0.015, a wider and more accurate color range, and higher fidelity; It is also stipulated that the brightness of mass-produced machines shall not be lower than 80% of the nominal value, effectively avoiding the problem of false brightness labeling. It is currently the mainstream projector brightness unit in China. Based on the majority of projection ANSI markings, a rough calculation shows that 1CVIA lumens are approximately equal to 1.7ANSI lumens.

Different usage scenarios have different requirements for projector brightness. If you are in a dimly lit and enclosed space such as a bedroom, and mainly watch at night, a projector with 1000-2000 ANSI lumens (approximately 588-1176CVIA lumens) can basically meet your needs and provide a comfortable viewing experience; If you are in a living room with ample daylight and often need to use a projector with lights on, you need to choose a product with a brightness of 3000 ANSI lumens (approximately 1765 CVIA lumens) or higher to ensure clear and bright images, allowing you to enjoy the pleasure of watching movies on a large screen both day and night.

The Paihao projector performs well in terms of brightness. Taking the Paihao H2 mini UST triple laser projector as an example, it has a high brightness of 5000 lumens, which is approximately 1500 ANSI lumens when converted to ANSI lumens (actual conversion standards may vary), making it highly competitive among similar products. This brightness can project clear and bright images even in the presence of ambient light in the living room during the day, allowing you to immerse yourself in the exciting world of film and television without having to close heavy curtains. Whether watching movies, TV dramas, conducting business presentations, or online learning, it can be easily handled, bringing users an excellent visual experience.

Resolution: Details create brilliance

Resolution is a key indicator for measuring the clarity of a projector's image. It is like the "eyes" of a projector, determining the richness of details in the image we can see. Simply put, the higher the resolution, the more pixels are included in the image, making it clearer and more delicate, and able to present more realistic colors and rich details; On the contrary, projectors with lower resolutions may have blurry and jagged images, and when zooming in, pixel blocks can still be clearly seen, seriously affecting the viewing experience. For example, when watching a Hollywood blockbuster, a high-resolution projector can allow you to clearly see the subtle expressions on the actors' faces, the texture of their clothes, and various details in the movie scene, as if you were there; However, low resolution projectors can greatly diminish these exciting moments, resulting in blurry images and an inability to truly appreciate the charm of the movie.

At present, common projector resolutions on the market include 480P, 720P, 1080P, 4K, etc. Among them, 480P has a lower resolution and limited image details, and has gradually been phased out by the market; 720P resolution can meet basic viewing needs, but for users who pursue high-quality visual experience, it may be slightly insufficient; 1080P resolution (1920 × 1080 pixels) is currently the mainstream choice, which can provide clear and smooth images. Whether watching movies, TV dramas, or playing games and entertainment, it can bring good visual effects; 4K resolution (3840 × 2160 pixels) represents a higher level of image quality, with four times the number of pixels as 1080P, richer picture details, and brighter colors, but at a relatively higher price.

When choosing a projector resolution, it is also important to pay attention to distinguishing between true and false 1080P. The key to this lies in the size of the display chip. At present, projectors mainly use DLP (Digital Light Processing) technology, and its core component is the DMD chip. The number and arrangement of micro mirrors on the DMD chip determine the native resolution of the projector. Generally speaking, the native resolution of a 0.47-inch DMD chip is 1080P. It has 2.07 million micro mirrors and can accurately project 1920 × 1080 pixels, presenting true 1080P image quality; The native resolution of the 0.33-inch DMD chip is only 720P, and it has 920000 micro mirrors, which can only project 1280 × 720 pixels. Some businesses, in order to enhance their product competitiveness, use XPR pixel displacement technology to achieve a "shaking 1080P" effect on projectors with 0.33-inch DMD chips, that is, by high-speed shaking micro mirrors, each micro mirror can form two pixels, approaching 1080P in terms of pixel count. However, the 1080P achieved in this way is not a true physical resolution, and there is still a certain gap between the picture details and clarity compared to real 1080P. So, when purchasing a projector, if you see a product advertised as 1080P resolution, be sure to check its DMD chip size. Only projectors that use a 0.47-inch DMD chip are truly 1080P and can bring you a better picture quality experience.

The Paihao projector performs excellently in terms of resolution. Taking the Paihao H2 mini UST triple laser projector as an example, it has a standard resolution of 1920x1080P and can support a maximum resolution of 8K. This means that it can not only easily present clear and delicate 1080P images to meet daily viewing and office needs, but also has strong compatibility and can play 8K ultra high definition videos, bringing users the ultimate visual enjoyment. Whether watching the latest blockbuster movies or experiencing the stunning visual effects brought by the Hollywood film industry; For business presentations, showcasing exquisite PPT documents and complex design drawings, the Paihao H2 projector can perform with its excellent resolution, presenting every detail clearly in front of the audience, making the picture vivid and leaving a deep impression.

Display Technology and Light Source: The Core Password for Image Quality

Display technology and light sources can be regarded as the "heart" and "energy source" of projectors, which together determine the image quality performance of projectors and are key factors affecting the projection effect. At present, the mainstream projector display technologies in the market mainly include LCD, 3LCD, and DLP, each with its unique working principle and advantages and disadvantages.

LCD (Liquid Crystal Display) technology is an early projection technology that controls the transmission and obstruction of light through the arrangement changes of liquid crystal molecules, thereby achieving image display. This technology has a relatively simple structure and low cost, but it also has obvious drawbacks. Due to the slow response speed of liquid crystal molecules, LCD projectors are prone to ghosting when displaying dynamic images, which affects the viewing experience; And its color expression is not rich enough, the color gamut is narrow, the color reproduction of the picture is not high, and it cannot present realistic and vivid colors. Nowadays, the market share of LCD projectors is gradually decreasing, mainly used in low-end products that do not require high image quality and are price sensitive.

3LCD (Liquid Crystal Display) technology is developed on the basis of LCD technology. It decomposes the white light emitted by a light source into three colors of red, green, and blue light through a prism, and then allows these three colors of light to pass through their respective LCD panels for imaging. Finally, the prism synthesizes the three monochrome images into a color image. The advantage of 3LCD technology lies in its excellent color performance. It can fully utilize the three primary colors of light to achieve high color brightness and accurate and delicate color reproduction. The color of the picture is bright, natural, and the transition is delicate. It is very suitable for scenes with high color requirements such as watching movies and appreciating art works. In addition, 3LCD technology uses three LCD panels working simultaneously, without color wheel rotation, and there is basically no rainbow effect. It is also less likely to cause eye fatigue when watching. However, projectors with 3LCD technology typically have larger volumes and relatively higher prices, and their lifespan may be affected due to the heat dissipation issues of the LCD panel.

DLP (Digital Light Processing) technology is currently one of the mainstream technologies in the projector market, and its core component is the DMD (Digital Micromirror Device) chip. The DMD chip is covered with tiny mirrors, each corresponding to a pixel point. By controlling the rapid flipping of these micro mirrors, different intensities of light are reflected to form images. The advantages of DLP technology are very significant, as it has high contrast and can achieve a contrast effect between deep black and high brightness, making the picture more clear in hierarchy and details; The response speed of the micro mirror is extremely fast, which can handle high-speed moving images well and is not prone to trailing phenomena. It is very suitable for watching sports events, playing games, and other dynamic scenes with many dynamic images. In addition, DLP technology projectors are usually small in size, light in weight, and easy to carry and install; Moreover, due to the fully sealed design of the DMD chip, it is not easily affected by dust, has a long service life, and has low maintenance costs in the later stage. However, some DLP projectors may experience rainbow effects when using color wheels for color separation, which means that when quickly switching between images, the edges of the image may flash like rainbow like stripes of color, which may affect the viewing experience for some color sensitive users.

Let's talk about the light sources of projectors. There are three common types: LED, laser, and light bulb. LED (Light Emitting Diode) light sources have the advantages of small size, long lifespan, high efficiency, and low energy consumption, and can be used continuously for up to 100000 hours. It has a fast startup speed, does not require preheating, and can immediately project images. Moreover, the color performance of LED light sources is constantly improving, and now the color gamut of some high-end LED projectors can reach a high level. However, LED light sources have relatively low brightness and are generally suitable for home projectors or small office projectors with low brightness requirements.

Laser light source is a rapidly developing new type of light source in recent years, which has advantages such as high brightness, bright colors, and long lifespan. The brightness of laser light sources can easily reach thousands of lumens or even higher, meeting the needs of various environments. Even in well lit environments, they can project clear and bright images. In terms of color expression, laser light sources have a very wide color gamut, which can present richer and more vivid colors. Their color saturation and restoration are better than LED light sources and traditional bulb light sources. In addition, the lifespan of laser light sources is also very long, generally reaching 20000-30000 hours or more, greatly reducing the user's usage and maintenance costs. According to different technical principles, laser sources can be divided into monochromatic lasers, two-color lasers, and tricolor lasers. Monochromatic laser converts blue laser into red, green, and blue colors through a fluorescent color wheel, with relatively low cost but slightly inferior color performance; Two color lasers and three color lasers use two or three types of lasers to directly mix the three primary colors, resulting in better color performance but relatively higher costs.

Light bulb light sources mainly include ultra-high pressure mercury lamps, xenon lamps, etc. Ultra high pressure mercury lamp is a commonly used light source in traditional projectors, with high brightness, which can meet the needs of some commercial, educational and other scenarios that require high brightness. However, the lifespan of light bulb light sources is relatively short, usually around 2000-5000 hours. After a period of use, the brightness gradually decreases and the light bulb needs to be replaced, which not only increases the cost of use but also brings some inconvenience. And the light bulb generates a large amount of heat during operation, requiring a powerful cooling system to ensure its normal operation, which also leads to a larger volume and higher noise of the projector. Although xenon lamps have excellent color performance, they are expensive, have a shorter lifespan, and have relatively few applications in the market.

The Paihao projector has a unique approach to display technology and light source selection. Taking the Paihao H2 mini UST triple laser projector as an example, it adopts DLP display technology and is equipped with a full-color laser light source. DLP technology endows it with high contrast, high definition, and excellent dynamic image processing capabilities, allowing users to enjoy a smooth and clear visual experience whether watching intense action movies or playing thrilling games, effectively avoiding problems such as image ghosting and blurring. The full-color laser light source brings it high brightness and excellent color performance. With a high brightness of 5000 lumens, it can effortlessly project clear and bright images in various ambient lighting conditions, even in living rooms or conference rooms with complex lighting during the day. In terms of color, the wide color gamut of full-color laser light sources can present richer, brighter, and more realistic colors, making every scene and character in the movie seem to come to life, bringing users an immersive visual feast. In addition, the long lifespan of the laser light source also makes the Paihao H2 projector have lower usage and maintenance costs, and users do not need to frequently replace the light source, making it more worry free and labor-saving.

Projection Ratio: The Secret of Small Space and Large Picture

Projection ratio is an easily overlooked but crucial parameter in projector selection. It is like a magical 'spatial magician', determining how large a projection image can be presented in a limited space. Simply put, the projection ratio is the ratio of the projection distance to the width of the image, and its calculation formula is: projection ratio=projection distance ÷ image width. The smaller this ratio, the wider the image that can be projected at the same projection distance; On the contrary, the larger the ratio, the farther the projection distance is required to project images of the same width.

For example, if a projector with a projection ratio of 1.2 wants to project a 2-meter wide image, the required projection distance is 2 × 1.2=2.4 meters; And another projector with a projection ratio of 0.8, when projecting an image with the same width of 2 meters, only requires a projection distance of 2 × 0.8=1.6 meters. From this, it can be seen that different projection ratios have a significant impact on the placement of the projector and the size of the image it can present.

When choosing a projector, it is crucial to select a product with the appropriate projection ratio based on the size of the room. If the room space is relatively spacious, such as a large living room with few space restrictions, then you can choose a regular telephoto projector with a slightly larger projection ratio. The projection ratio of this type of projector is usually between 1.5-1.9. They are relatively affordable in price and can project large images of considerable size in a larger space, meeting the needs of a family sitting around watching movies and TV. For example, in a living room with an area of 30 square meters, using a projector with a projection ratio of 1.6, a large screen of about 120 inches can be easily projected at a distance of about 4 meters from the wall, bringing a stunning visual experience.

However, if the room space is limited, such as a small bedroom area, or if you want to use a projector in a compact study or small conference room, you need to choose a short or ultra short focus projector with a smaller projection ratio. When the projection ratio is less than 1, we usually refer to it as a short focus lens; When the projection ratio reaches 0.4 or below, it belongs to an ultra short focal length lens. Short focus and ultra short focus projectors can project large-sized images over a short distance, effectively saving space. Taking the ultra short focal length projector with a projection ratio of 0.3 as an example, it only needs to be about 0.5 meters away from the wall to project a large 100 inch image, which is very suitable for use in small spaces. In a bedroom with an area of only 15 square meters, placing an ultra short focus projector near the head of the bed can project clear large images onto the wall at the back of the bed, allowing you to enjoy an immersive viewing experience while lying in bed without worrying about insufficient space.

The Paihao projector has a significant advantage in terms of projection ratio. Taking the Paihao H2 mini UST triple laser projector as an example, it adopts ultra short focus technology with a projection ratio as low as 0.23:1. This means that it can project ultra large images within a very short distance. In practical use, with a distance of just over 20 centimeters, an 80 inch large screen can be projected; If the distance is increased to around 42 centimeters, it can project a super large image of 100 inches. For users living in small-sized houses or with limited room space, this advantage of the Paihao H2 projector is undoubtedly a great blessing. It can be easily placed on TV cabinets or even wall mounted, without the need to leave a large space in the middle of the room for equipment placement like traditional telephoto projectors, greatly saving space and allowing users to enjoy the stunning visual effects brought by large screen projection in limited space. Whether watching movies, playing games, or conducting online learning or business presentations, the Paihao H2 projector can provide users with a convenient and comfortable user experience with its excellent projection ratio performance.

When you turn on the projector, it is like a well-trained photographer, quickly and accurately focusing on the image without the need for manual adjustment. In just a few seconds, it can present clear and sharp images. This feature not only saves valuable time, but also allows you to bid farewell to the tedious and troublesome manual focusing in the past. Imagine, after a busy day, you can't wait to watch a movie to relax your mind and body. Simply press the power button, and the Paihao H2 projector will instantly prepare clear images for you, allowing you to immerse yourself in the exciting plot. This convenience and efficiency undoubtedly greatly enhance the user experience.

The trapezoidal correction function is also a major highlight of the Paihao projector. In practical use, it is difficult to ensure that the placement of the projector is always completely perpendicular to the projection screen or wall, which can cause trapezoidal deformation of the image and seriously affect the viewing effect. The Paihao H2 projector is equipped with a powerful automatic trapezoidal correction function, which can quickly detect and automatically adjust trapezoidal deviations in both horizontal and vertical directions. Through built-in high-precision sensors and intelligent algorithms, it can perform real-time analysis and correction of the image, ensuring that the image always remains square and neat. Even if you place the projector casually on the coffee table, bedside, or even on a slightly tilted desktop, it can easily handle it and present you with a perfect rectangular image. This intelligent design makes the placement of the projector more flexible and free, ensuring that you enjoy the best visual effects in any scene.

The Paihao projector also has intelligent obstacle avoidance function, which is like giving the projector a pair of "smart eyes", allowing it to sensitively perceive the surrounding environment. When it detects obstacles in the projection area, such as wall sockets, decorations, window frames, etc., it will automatically adjust the position and size of the image, accurately avoid obstacles, and ensure the integrity and continuity of the projection image. For example, when you use a Paihao projector in your bedroom, the bedside lamp may be located on the projection path, and the intelligent obstacle avoidance function will come into play. The projector will automatically avoid the position of the lamp, so you don't have to worry about the image being blocked. This not only improves the projection quality, but also avoids the inconvenience caused by human adjustment, providing users with a more intimate and intelligent user experience.

The screen flipping function adds more possibilities to the usage scenarios of Paihao projectors. Whether it's hanging the projector from the ceiling, placing it under a table for rear projection, or flipping the image horizontally or vertically, the Paihao projector can easily achieve it. You only need to use the settings menu of the remote control or projector, with a few simple steps, to quickly adjust the direction of the screen to meet different installation methods and usage needs. In the conference room, for the convenience of attendees, you can hang the projector and set the screen to flip, making the projected image more intuitive; Placing the projector behind the sofa for rear projection during family gatherings can also provide a unique viewing experience for everyone.

In terms of operating system, the Paihao projector also has excellent performance. Taking the Paihao H2 as an example, it is equipped with the Android 9.0 intelligent operating system, with a simple and intuitive user interface, easy to operate, and even first-time users of projectors can quickly get started. A rich app store provides users with a massive amount of application resources. You can download various movies, games, education and other applications according to your preferences. Whether it's watching popular movies and TV shows, playing exciting big screen games, or
