Color dispersing unit, and liquid crystal display device

Abstract

The invention relates to a color light-splitting component and a liquid crystal display device using the component. The color light-splitting component provided by the invention includes a grating with a plurality of grating unit groups, the grating unit groups being composed of at least one grating unit, the grating unit being used for separating incident white light into red light, green light and blue light to exit, the grating using piezoelectric materials; a plurality of drive control units corresponding connected to the plurality of grating unit groups, the drive control units enabling the piezoelectric materials to deform so that the grating span of the grating unit changes. The color light-splitting component of the invention can replace the filter, and realize the colorization display of the liquid crystal display device.

Description

【Technical field】 [0001] The invention relates to a color light splitting element and a liquid crystal display device using the color light splitting element. 【Background technique】 [0002] The liquid crystal display device is a passive display device. In order to achieve the effect of color display, it is necessary to provide a color filter device. The color filter device can cooperate with other components such as electrodes and liquid crystal panels to realize color display. [0003] see figure 1 , a color filter device 1 of the prior art includes: a substrate 10, a plurality of black matrices 12 are periodically arranged on the substrate 10, and a red filter element 13, a green filter element 14, a blue filter element Element 15 and conductive material 11 attached to the three color filter elements 13, 14 and 15. [0004] The above-mentioned color filter device 1 will attach required red filter elements 13, green filter elements 14 and blue filter elements 15 between ...

Problems solved by technology

However, when the light passes through the pigments of the red filter element 13, the green filter element 14, and the blue filter element 15, the light component of the light will be reduced, thereby reducing the brightness of the display.

[0006] In addition, the above-mentioned color filter device 1 cannot ensure that the above-mentioned color filter elements 13, 14, and 15 are neatly distributed on the surface of the substrate 10 in sequence, and it is easy to make adjacent filter elements overlap each other, resulting in overlapping regions 16, or It is the phenomenon that the distance between adjacent filter elements is too large, resulting in light leakage

In addition, the tiny protrusions or depressions produced on the surfaces of the filter elements 13, 14, and 15 make the color shades uneven when the light passes through the protrusions or depressions.

[0007] The uneven color depth produced by the color filter device will seriously affect the display quality of the liquid crystal display device
