The lustiness determines what determines the projector's color performance. The first is the projector light source. Traditional projectors use ultra-high pressure water and gold lights. Everybody knows that the light emitting principle of a light bulb is to energize a light bulb filled with rare gas, making rare gas. Ionization occurs and high pressure discharges excite the gas to produce visible light. Obviously this kind of high-intensity gas discharge light source is not pure, and a lot of messy light will affect the color of the projected picture. We have tested many ultra-high pressure water gold and xenon lamp projectors. Most of their NTSC color gamuts are around 60%. Obviously, this kind of performance cannot meet the needs of users completely. This is why we all thought that projector screens were not good in the past. 
The appearance of the traditional ultra-high pressure water gold light LED has effectively changed this situation. Our friends who care about our projector evaluation should remember that most of the LED light source products can have more than 80% NTSC color gamut. Because the LED light source can emit pure red, green and blue colors without disturbing light interference, the picture effect will naturally be greatly improved. The 20% progress means a more colorful picture, and the viewing experience of the audience has been greatly improved. The emergence of the laser is even more to the brightness and color performance of the entire picture. At the same time, the performance of the laser is more stable, and there will be no problems such as fading, brightness decay and the like when used for a long time.
No. 2: Not only are the light sources affecting the color, but there are many other factors besides the light source that restrict the color. The color wheel is also a problem that cannot be ignored. Although the projectors on the market today are mostly six-stage color wheels, the colors of the remaining three color wheels except the three RGB segments are not the same, and some projectors have selected white segments in order to increase the brightness. Others use RGBRGB loop segments for richer colors. This is the reason why many projections have similar color gamuts in NTSC, but the reason why the color of the projected picture is greatly different. As already mentioned, each person's understanding of color is not the same, so if you want to evaluate the color of a projection screen, you can only rely on your own personal experience. 
The color wheel is an important factor that restricts the color of the screen. The color temperature debugging also affects the color performance of the screen. The color temperature standard of the projector is 6500K, and the picture color higher than 6500K will be cooler, whereas the picture will be warmer, and the cold or warm picture will cause color drift and affect the actual viewing experience of the user. For a projector, brightness is an important indicator of the color temperature. For example, a 1000 lumen LED projector, in order to screen effect, the color temperature will usually reach more than 9000K. Obviously, this picture color must be too cold, and the color performance will not be too good.
The curtain is actually a problem that we often overlook. When people use it everyday, many people are accustomed to projecting directly onto the wall. They think that they are all white walls. The projection effect should be similar. In fact, this is not correct. First, the anti-light curtain absorbs visible light and enhances the brightness of the screen. In addition, although the wall looks white, in fact, it will have a color cast, which is difficult to distinguish by the naked eye, virtually affect the color performance of the projection screen. 
The curtain is a problem that everyone can easily overlook. In addition, in terms of the adjustment of the color standard, each projector manufacturer has its own set of standards and methods. Many manufacturers use their own technologies and users to research the screen requirements. This is why we usually see different projectors even though the NTSC color gamut is similar, but the actual color difference of the projected images is large.
There are many factors that affect the color performance of a projection, and each viewer's judgment on color is also very different. Therefore, in this respect, brightness cannot be expressed as an objective numerical value. So if you want to buy a projector, it is best to personally feel the projection screen, if you only use the objective indicators to sloppy shot, I am afraid it is likely to regret it.
What determines the performance of a projection projector? The brightness, resolution, contrast, and color of the screen are the most important indicators. Different from the previous ones, the color of the screen cannot be determined by a single objective value. At the same time, everyone's favorite color styles are different, so it is not easy to evaluate the color performance of a product. Today the author came to talk to you about what determines the color performance of a projection.
