Problems solved by technology

[0005] However, although the existing color filter 100 can display color images, its basic pixels 121, 122, 123 have fewer color types, only red, green, and blue. In practical applications, the basic pixels 121, 122 may be The color gamut that can be displayed by the composite pixel composed of 123 and 123 is not wide enough
In addition, since each basic pixel 121 / 122 / 123 only allows light of one color to pass through, the existing color filter 100 has low energy utilization efficiency of the backlight light source, which may lead to insufficient brightness of the liquid crystal display.

Embodiment Construction

[0013] see image 3 and Figure 4 , a preferred embodiment of the present invention is a color filter 200, the color filter 200 is used in a liquid crystal display, which includes a substrate 20, a light shielding portion 21, a filter portion 22 and an electrode layer 23 .

[0014] The substrate 20 is a transparent smooth flat plate made of glass, and other parts of the color filter 200 are stacked on the substrate 20 . The light-shielding portion 21 is a mesh structure made of light-shielding materials such as black resin film or chrome film, and is used to prevent light leakage and unnecessary reflection between pixels of the liquid crystal display. The shading portion 21 has a plurality of fine regular triangular grids (not shown), wherein every six adjacent regular triangular grids share a vertex to form a regular hexagonal grid group (not shown).

[0015] The filter part 22 is composed of red (red, abbreviated as R in the figure), green (green, abbreviated as G in the ...

Abstract

The invention discloses a colored optical filter comprising a substrate and a filter part formed on the substrate. The filter part comprises a plurality of composite pixels for displaying the colors, wherein each compound pixel comprises six basic pixels in different colors; and colored emitting light rays can be formed by mixing the emitting light rays in six colors formed through the six basic pixels.

Description

technical field [0001] The invention relates to a color filter, in particular to a color filter with an improved pixel structure. Background technique [0002] LCD screens are widely used in both work and life. Since the liquid crystal layer itself encapsulated in the liquid crystal display can generally only present black and white under the action of an electric field, color images must be displayed through the color filter installed on it. Therefore, the color filter is an important part of the liquid crystal display One of the most important parts. [0003] see figure 1 and figure 2 , a conventional color filter 100 generally includes a substrate 10 , a light shielding portion 11 , a filter portion 12 and an electrode layer 13 . The substrate 10 is a transparent and smooth flat plate made of glass, and the light-shielding portion 11 is formed on the substrate 10, which is a matrix structure with a plurality of fine rectangular grids made of light-shielding materials...
