The black crystal high-temperature sintering process was first adopted. In addition to the ordinary LCD screen, there is another layer of filter screen, which effectively improves the reflection intensity after the light hits the screen, making the look and feel more comfortable. The filter screen is not ordinary glass, but the inner side of optical glass is sprayed with a special black crystal coating. Due to the effect of black crystal coating, the light transmittance is greatly improved, and the contrast and brightness of LCD are directly improved, which is helpful to improve the display effect and protect the user's vision. The screen is not made by Haier itself, but is made by Samsung. In fact, many brands of notebooks use the screens of Samsung, LG and Philips.
