Embodiment Construction

[0050] figure 1 It is a schematic diagram of a color light guide plate in a preferred embodiment of the present invention. Please refer to figure 1 , the color light guide plate 100 is suitable for color-separating an incident light L. The color light guide plate 100 includes a substrate 110 and a color light output structure 120 . The substrate 110 has a plurality of pixel regions 112 . The colored light output structure 120 is disposed in each pixel region 112 , and the colored light output structure 120 includes: a first nano pattern 122 , a second nano pattern 124 and a third nano pattern 126 . The incident light L is scattered by the first nanopattern 122 into the first color light L1 , is scattered by the second nanopattern 124 into the second color light L2 , and is scattered by the third nanopattern 126 into the third color light L3 .

[0051] Please continue to refer to figure 1 The material of the substrate 110 may be glass or transparent resin, wherein the transp...

Abstract

The invention provides a colour light guide plate which is suitable for incident light color separation and comprises a base plate and a color light output structure, wherein, the base plate is provided with a plurality of pixel areas, and the color light output structure is arranged in each pixel area; the color light output structure comprises a first nanometer pattern, a second nanometer pattern and a third nanometer pattern. The incident light is scattered by the first nanometer pattern to form first color light, is scattered by the second nanometer pattern to form second color light and scattered by the third nanometer pattern to form third color light. The color light guide plate can output the consistent first color light, second color light and third color light having high brightness. Besides, a liquid crystal display device with the color light output structure is also provided.

Description

technical field [0001] The present invention relates to a light guide panel and a display device, and in particular to a color light guide panel (Color Light Guide Panel) and a liquid crystal display device (Liquid Crystal Display Device) with a color light output structure (Color Light Output Structure) . Background technique [0002] With the development of optoelectronic technology and semiconductor manufacturing technology, Flat Panel Display (FPD), such as liquid crystal display device, has gradually become the mainstream of display products. Generally speaking. The liquid crystal display device includes: a backlight module and a liquid crystal display panel, wherein the liquid crystal display panel is composed of a thin film transistor array substrate, a color filter substrate and a liquid crystal layer between the two substrates. [0003] When the existing color filter substrate is used, each single pixel is composed of three sub-pixels, and each sub-pixel is contro...
