Structure of colorful spectral filter

Abstract

The present invention discloses a color filter structure which is provided with a transparent baseplate; a plurality of pixels are formed on the baseplate, wherein, each pixel is provided with a first color zone, a second color zone and a third color zone, in particular each pixel is an isosceles trapezoid; each two pixels are spliced to a regular hexagon; three identical regular triangles are in rabbet joint inside each isosceles trapezoid; three regular triangles respectively correspond to the first color zone, the second color zone and the third color zone, and after each two pixels are spliced to the regular hexagon on the transparent baseplate, with an arbitrary regular hexagon as the center, six regular hexagons spliced by other pixels in two are faveolately in scarf joint around. The color filter with the structure has good color display effect and can weaken sawtooth in the margin of image when the image is displayed obliquely.

Description

technical field [0001] The invention relates to a color filter technology, in particular to a structure of a color filter. Background technique [0002] Liquid crystal display (LCD) is the current mainstream display, and the color filter part provides color display for the liquid crystal display, and the display device composed of a thin film transistor (thin film transistor) array can display different color images. the goal of. [0003] Referring to FIG. 1 , it is a schematic plan view of a color filter in the prior art. The color filter is composed of a plurality of pixels arranged in an orderly manner, and each pixel is composed of three sub-pixels R (red), G (green) and B (blue). This arrangement is simple in structure and easy to manufacture, but the disadvantage is that assuming that a rectangular area has the same length and width as the length and width of a pixel, each sub-pixel in each pixel of the color filter of this structure Concentrated in one rectangular ...

Problems solved by technology

This arrangement is simple in structure and easy to manufacture, but the disadvantage is that assuming that a rectangular area has the same length and width as the length and width of a pixel, each sub-pixel in each pixel of the color filter of this structure Concentrated in a rectangular area, therefore, it is easy to cause uneven color mixing, and the color display effect is not good

[0005] Referring to Fig. 2, U.S. Patent No. 5,216,414 provides a structure in which sub-pixels are arranged in a mosaic, although each sub-pixel in each pixel of the color filter of this structure is still concentrated in a hypothetical area, but its The sub-pixels are misaligned between adjacent pixels, thus enhancing the color mixing effect

[0006] In addition, in the above examples, there is another problem: because the pixels and sub-pixels of the color filter are arranged in a rectangular grid, when the liquid crystal display needs to display oblique images, the edges of the images Jaggies will be more obvious, especially when the image edge contrast is strong
