Why Are Led Lights Slightly Projection Or Clumsy? Led Enables The Projector Light Source To Have a Short Board

The most important thing about home projection is two things. The first is color, and the second is brightness. For projector products, color and brightness are inseparable from the story. The brightness of high-grade household projector won't be too high commonly, because brightness is tall, colour performance is difficult accurate. Generally speaking, the brightness of household projector exceeds 10000 yuan, basically control the level of 2000 lumens. If the brightness of the home projector reaches 4000 or even 5000 lumens, the color performance of the projector is not the best state of current technology reserves.

LED light source is slightly projection or awkward
It is widely believed that the brightness is too high, and the projector's color is difficult to adjust to the optimal condition. In fact, the color of the projector is too low to get the best color of the projector. This is something that many average consumers don't know. For LED microprojectors, due to the current emission efficiency of the LED light source, the brightness is difficult to break through 1000 ANSI cavities, and even the actual test brightness of many introduced products is at the level of 200 ANSI cavities, which is CO. With this light source, the brightness is lit up, so there is a part of the LED micro projector. Colors don't perform well.

Although LED light source is tricolor light source, but the color purity is high, can provide a high color gamut effect, but in fact, due to the low brightness of LED light source, manufacturers have a certain tendency to optimize the color of the picture. The more accurate the color performance, the better, if the brightness is sufficient. However, the LED light source is not bright enough, so the color temperature needs to be increased. This will give people a more vivid picture. In practical tests, some LED microprojectors have exceeded 100000 K(the standard value is 6500 K), which naturally affects the color effect of the picture.

The color that ordinary follow a drama entry-level micro cast is still not a problem
LED enables the projector light source to have a short board
To make the picture brighter, the LED microprojector raises the color temperature, a factor that affects the color of the projector screen. And the LED light source itself is not perfect, blue LED color is not standard, that is to say, the blue part of the LED due to technical reasons, blue is not pure, its wavelength and three primary color standard blue wavelength error. So the blue performance of LED microprojectors is actually a little bit purple. This is not a manufacturer's sloppy optimization, it's a problem with current LED lighting technology.

Three entry-level microprojection pictures can show three projectors with color reduction not very accurately.
There's also the question of the brightness of the color. There are actually two levels of brightness on the projector screen. The first one is the brightness of the white light. One is color brightness: that is, the projector shows brightness. Ss in different colors. If the brightness value of the RGB tri-color is added to the white light, we would say that the color brightness of the projector is sufficient. If the values of the RGB colors do not add up to white light, then the color brightness of the projector is not sufficient.

Whether color brightness is more important to force. Since the instrument can measure the brightness of white light, reliable values can be obtained. However, if the color is high enough, the human eye will actually perceive the image as brighter than white light. If the color is not bright enough, the color of the human eye will not look so high. High brightness gives the illusion that the picture is very bright, which is a characteristic of the human eye.

White light is commonly used for projector testing.
Currently, the brightness of the LED light source is actually somewhat different from the brightness of the white light, especially the brightness of the lead product, so although the brightness of the white light was tested, the micro projector's brightness reached the ANSI brightness of 200, but the Wh. Consumers still feel that the images are not bright enough because of the rich colors. .

So the color performance of LED micro projector is not very good, which is a comprehensive problem, and the technical limitations of LED light source itself are related, of course, the main reason is that the brightness of LED lamp is not enough, if the brightness is enough, then the space for color debugging. ING is the most important. Of course, the higher the brightness of the LED microprojector, the more accurate the color performance. In fact, LED micro projector screen color problems are mainly reflected in the entry level products.

There are some HLD projectors that have good color performance. The appearance of this bright LED projector indicates that the color of the LED light source will gradually improve. Of course, the color representation of the product is not accurate, but watching TV series and pursuing entertainment is not a problem. After all, the micro projector is not positioned as a professional home theater projector. 2000 yuan for a super large screen, I believe it is worth affirming. We don't have to be too picky about its color performance. If you care about color, consider buying specialty products.

The above is why the LED light source slightly projection or clumsy, LED projector light source has a short board, the color brightness of the LED light source is actually a certain gap with the brightness of the white light, Pan science manufacturing excellent LED light source, to provide you with stable and high effect of the light source.
