LGD new panel effectively enhance color gamut

LG introduced the latest Nano Cell LCD panel at CES 2017. This panel is mainly made by adding a layer of particles with a uniform size of about one nanometer in diameter between the Cell and the polarizer. Usually, the panel uses particles with a diameter of about 12 nanometers. The TV is made with Nano Cell LCD panel, which can absorb the extra light in the light, make the screen display more color purity, and can filter different colors, so that the color has a higher accuracy.

According to the industry, LGD's color filters for increasing the amount of dyes can be used in LCD and OLED TV products. High-end TV products equipped with such color filters are expected to be available in 2018. Process and yield will affect the color gamut of television, but if the proportion of dyes increases, the theoretical color gamut and color uniformity will definitely increase.

For a long time, the raw materials of color filters are mainly pigments, because the dyes are easily sublimated and discolored during the high temperature process. Therefore, although the color gamuts exhibited by the dyes are better, the persistence problem is criticized. Fortunately, academics and industry have developed dyes that can withstand high temperatures. From 2-3 years ago, panel makers began to use color filters that mixed dyes and pigments, so that the two materials can be mutually shortened, and the mixing ratio is different. The home owners are adjusted according to process and technology.
