Abstract

The present invention relates to a liquid crystal display. It possesses several color filters of red, green and blue three pixels and a backlight source. When suppose maximum luminance value of backlight source spectrum is about 1.0, the sum of products of luminance of backlight source spectrum and transmissivity of color filter of blue pixel about less than or equal to 2.0 in wavelength range of 490 nano to 540 nano, so that it can make the transmissivity spectrum of color filter and spectrum of backlight source be coordinated so as to obtain maximum representative colour gamut and can meet correspondent colour coordinate.

Description

technical field

[0001] The present invention relates to a liquid crystal display with high color performance (high gamut), in particular to a liquid crystal display that can use a backlight source other than a fluorescent tube to meet the requirements of human eyes for color performance. Background technique

[0002] Thin film transistor-liquid crystal display module (thin film transistor-liquid crystal display module, TFT-LCD module) has been widely used in various displays, such as figure 1 Shown is a schematic cross-sectional view of a TFT-LCD module. However, due to the influence of the color filter of the TFT-LCD module and the optical characteristics of the liquid crystal, the color performance presented by the TFT-LCD module is less saturated, so the high color reproduction (color reproduction) in the TFT-LCD module ) becomes one of the important characteristic parameters. Therefore, various international standard organizations formulate a variety of color specifica...
