Liquid crystal display apparatus and backlight source generation method

Abstract

The invention pertains to liquid crystal display field, provides a liquid crystal display apparatus and a backlight source generation method, the liquid crystal display apparatus comprises a liquid crystal panel and a backlight system, the system comprises a plurality of luminescent clusters, each cluster comprises three luminescent groups of RGB, each group is composed of a plurality of LED luminescent units with different spectrums. The wide-spectrum liquid crystal backlight source generation method, comprises steps of: setting a plurality of LED luminescent units with different spectrums toform luminescent clusters; selecting a plurality of luminescent units of the luminescent clusters to form the three luminescent groups of RGB, setting drive parameter to each LED luminescent unit according to luminescent color, and executing time sharing drive to the three luminescent groups of RGB in field sequential display mode. The inventive liquid crystal display apparatus has backlight source with wide spectrum, thereby showing approximate real color of natural object, to make it comfortable to observe.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, in particular to a liquid crystal display device and a method for producing a backlight source thereof. Background technique [0002] In the natural world where people live, the spectrum of visible light of objects observed by eyes is rich and often continuous. However, for a liquid crystal display device using a common CCFL or LED backlight, the light emitted by the backlight source is discontinuous in several limited spectral bands. The color we see from the LCD TV is the result of mixing the above discontinuous spectral segments. This method is a simplified processing method for complex colors. It can only basically reproduce the original color of the scene. The color of the actual object has a large difference in the spectral composition. figure 1 , figure 2 , image 3 The difference between the reflection spectrum of the natural object of the same color and the display spectrum of ...

Problems solved by technology

However, the spectral line bandwidth of the backlight RGB LED of the liquid crystal display device is much lower than that of the imaging three primary colors. This kind of spectral line color with a narrow half-peak width to simulate a spectral line color with a wide half-peak width will cause The distortion of the image color of the liquid crystal display device often presents a color that is too green or too red. Although the color gamut of the backlight color of the liquid crystal display device is very wide, the realism of the image is poor, and it is more suitable for continuous spectrum light than people. Compared with the natural environment, there is a big difference
