Problems solved by technology

The difficulty faced by the existing technology is that by adjusting the doping ratio of red phosphor and green phosphor, although the overall color temperature of the color picture displayed on the LCD TV can be maintained at 10000K
However, when the overall color temperature of the color picture is maintained at 10000K, it usually cannot meet the NTSC standard
If the doping ratio of red phosphor and green phosphor is adjusted again in order to meet the NTSC standard, the overall color temperature of the color picture will no longer be 10000K
Therefore, there will be a dilemma that the color picture cannot meet the overall color temperature of 10000K and meet the NTSC standard at the same time

Abstract

The present invention discloses a display module which comprises a liquid crystal module and a backlight source. The liquid crystal color filter is provided with a color filter with a plurality of penetration ratios. The backlight source is provided with a radiation frequency spectrum which has a plurality of peak values of light intensity. A plurality of color proportional relationships are provided between the plurality of penetration ratios and the plurality of peak values to make that a color image which is generated by a light emitted by the backlight source after penetration the color filter has a prearranged brightness and a prearranged saturation degree. More concretely, the prearranged brightness is that the whole color temperature of the color image is sustained to a Kelvin scale of ten thousand. The prearranged saturation degree satisfies the standard of national television standards committee.

Description

technical field [0001] The invention relates to a display module, in particular to a display module which enables a displayed color picture to have a preset overall color temperature and a preset saturation through a plurality of color ratio relationships. Background technique [0002] With the continuous improvement of manufacturing technology, liquid crystal displays have developed many advantages, such as lightness, thinness, power saving and no radiation. Based on the above characteristics, liquid crystal display has been widely used in various electronic products, such as personal digital assistant (personal digital assistant; PDA), notebook computer, digital camera, digital video camera, mobile phone, computer screen and LCD TV, etc. . However, since the liquid crystal display panel itself cannot emit light, a light source device is required to supply light to the liquid crystal display panel to display images. [0003] As for a liquid crystal television using a liqu...
