LCD display module

Abstract

A liquid crystal display module, consists of one backlight module and one liquid crystal display panel. The backlight module is suitable for emitting at least one of the first color light, one of thesecond color light and one of the third color light, in which the wavelength of the first color light is 450nm to 460nm, and that of the second color light is 520nm to 540nm, the third color light is610nm to 630nm. The liquid crystal display panel consists of one color filter substrate, one active component array substrate and one liquid crystal layer, in which, the color filter substrate has atleast one of the first filtering layer, one of the second filtering layer and one of the third filtering layer, suitable for the transmission of three colors of lights mentioned above. In which, the peakvalue of transmitted light for second filtering layer is 520nm to 540nm, and the half-power frequency width of transmitted light for second filtering layer is 90nm to 120nm, ensure the NTSC ratioof l iquid crystal display module between 72% and 90%.

Description

technical field [0001] The invention relates to a liquid crystal display module, in particular to a liquid crystal display module which can effectively improve the brightness of a liquid crystal display panel. Background technique [0002] Liquid crystal displays have advantages that cannot be achieved by displays made of traditional cathode ray tubes (Cathode Ray Tube, CRT), such as low-voltage operation, no radiation scattering, light weight, and small size. Compared with other flat-panel displays, such as plasma ( Plasma) displays and Electroluminance (EL) displays have become the main subjects of display research in recent years, and are even regarded as the mainstream of displays in the 21st century. [0003] The conventional liquid crystal display includes a backlight module (Backlight Module) and a liquid crystal display panel (Liquid Crystal Display Panel). Wherein, the backlight module has a light source device, which includes light emitting diodes (Light Emitting ...

AI Technical Summary

Problems solved by technology

However, as the purity of the filter layer of the color filter substrate increases, there will be relative disadvantages such as an increase in manufacturing cost, a decrease in the light transmittance of the color filter substrate, and a decrease in the display brightness of the liquid crystal display.

It is worth mentioning that the NTSC ratio displayed by CRT monitors in the past is usually maintained at around 75%, but this display effect is sufficient to meet the needs of ordinary users

In other words, the current design direction of high color purity and high display quality is constantly moving. Although the production cost has been greatly increased, the relative benefit that it can improve is quite limited.
