In recent years, mainstream projector manufacturers have successively introduced HLD solid state new light source products. Especially in the education market, HLD new light source technology has received increasing attention from manufacturers and users due to its outstanding color performance. As an emerging technology, HLD light sources have been able to have such superiority. The color expressiveness, let us open the secret from the perspective of color gamut, color rendering and color temperature.

Before introducing the concept of high color gamut, let us first understand the concept of the color gamut. The color gamut refers to the range of colors that can be expressed by the display device. In theory, the larger the color gamut, the more colors that can be displayed. The more colors the human eye sees, the more accurate and realistic the colors are. Specifically, high color gamut projector products have more kinds of colors, making the color transition in the picture more natural, effectively avoiding distortion and color. The situation of the block appears. Moreover, more types of colors can make the screen level more distinct, able to show more details and closer to the real effect.
From the horseshoe color gamut, we can see that the gamut coverage of the projector with HLD light source is very strong, and the solid colors such as red, green, and blue are basically distributed in the periphery of the gamut space, which is beyond sRGB's. Standards, even broader than the market's color gamut of mainstream home projectors, can truly restore color.

Regarding the concept of high color gamut, after the introduction, we must have had a preliminary understanding. For the high gamut projectors on the market, let's take a closer look at the performance of the color gamut. The old projector manufacturer NEC in 2018 The new CU4200WD series educational projector adopts HLD new light source, further enhances its color performance to high color gamut standard, can present richer colors, and enables educational users to obtain a true and rich color performance experience. It is worth mentioning that NEC Education's new product series has been rigorously certified and selected. Currently, it has passed the certification of high color gamut products and became the first projector in the education industry to achieve high color gamut certification. NEC's new series is also designed with LCD panels. The advantage of color is obviously indispensable.

It is not enough for the projector product to have a wider color gamut range, but it is also necessary to achieve accurate color reproduction so that rich colors can make a real effect. It is not difficult to see that the spectral image band of the HLD light source is compared with that of the conventional solid-state light source. The proportion of blue light in the HLD spectrum is lower. It has a more continuous spectral band, better color rendering, and a higher degree of true color reproduction. Even complex teaching courseware can accurately display.
Continuity Spectrum of HLD Light Sources Provides Higher Color Rendering
In addition to the above-mentioned high color gamut and high color rendering feature addition, NEC HLD LCD education projectors are set at a color temperature of 6500K, and the presented screen effects can effectively avoid division growth time, resulting in close viewing. Glare, dazzling and other discomforts, the human eye feels more comfortable.

We see that it is the high color gamut, high color rendering, and suitable color temperature advantages of the HLD light source that make it possible to bring us an outstanding color experience. We have reason to believe that in the future, the HLD will be based on its color aspects. Breakthrough will redefine the projection industry for us, and the NEC HLD LCD education projector series with such outstanding color expression will have the opportunity to lead the ever-changing educational display field again.
