The solid color hard-screen panel is a major breakthrough in the TV's wide color gamut improvement program. By adding nano materials to the display structure, it specifically absorbs the stray light emitted by the backlight, thereby enhancing the purity of the three primary colors of red, green and blue on the basis of achieving a wide color gamut. It makes it have a wide and unrestricted perspective while the colors are more accurate and the picture is more real.
The difference between solid color hard screen and ordinary LCD TV
Let's talk about the principle of TV LCD screen display first. Electronic display devices are based on an important optical principle, namely the additive color mixing method. That is, the colors of the three primary colors (red, green, and blue) can be added in different proportions to mix most of the colors. The difference between the LCD TV and the solid-color hard-screen TV is that there are different processing technologies for the superposition of the three primary colors.
"Quantum dot panel display principle"
Among them, the display structure of the LCD screen is mainly composed of a backlight tube, a liquid crystal glass and a TCON control board. The backlight tube emits uniform white light behind the liquid crystal glass. The LCD TV motherboard sends an LVDS signal to the TCON control board and the TCON control board. The image signal is decoded, and different voltages are used to control the deflection of the liquid crystal at different pixels. The liquid crystals of different pixels are combined, and each pixel has three small blocks of R, G, and B (red, green, and blue). Different degrees of liquid crystal deflection will transmit different degrees of white light, resulting in three small blocks of R, G, and B. Different brightness, mixed together to present a color, and finally presented in front of us.
More quantum dot TVs and OLED TVs on the market are also improved on the basis of ordinary liquid crystal panel display technology, hoping to improve the color performance of the TV and get closer to the real world color, which often needs to be resolved The core contradiction of the impure three primary colors and the narrow color gamut.
"Principle of solid color hard panel display"
Both solid color hard screen technology and traditional quantum dot liquid crystal technology are wide color gamut technologies. However, compared with the quantum dots that emphasize the improvement of the vividness of colors, the solid color hard screen technology mainly focuses on the improvement of the purity of the picture color, which is a "purification" technology of the picture color. Nano-materials are added to the solid-color hard-screen panel, which is specifically used to absorb the stray light emitted by the backlight to improve the purity of the three primary colors of red, green and blue, so that more rich colors can be more accurately and realistically presented. The screen is more advanced than other LCD technologies.
In addition, the solid color hard screen technology also has the advantage of making the TV viewing angle wider and the picture more stable. It is understood that the chromatic aberration of the traditional LCD screen when the viewing angle is greater than 30 degrees will be very obvious, while the solid color hard screen has no chromatic aberration when the viewing angle reaches 60 degrees, maintaining a 100% high color gamut, forming the most realistic image .
