Problems solved by technology

[0004] In addition, even if white light emitting diodes are produced under the same process conditions, the light emitted by different white light emitting diodes will still have different optical characteristics or even greatly differ from each other.
In this way, these optical differences will be directly reflected on the liquid crystal display, so that the liquid crystal display of the same specification will present different display effects, thereby reducing the quality of the liquid crystal display

Abstract

A color filter and a display are disclosed. The color filter includes a base plate, a plurality of colored light-filtering units and a penetration rate adjustment laminated layer. The colored light-filtering units are arranged on the base plate. The penetration rate adjustment laminated layer is arranged on the base plate and covers the colored light-filtering units. The penetration rate adjustment laminated layer comprises a transparent conducting layer and an inorganic dielectric layer. The light penetrating through the color filter can have better luminance performance through adjusting thethickness of the penetration rate adjustment layer, so the display adopting the color filter can have excellent display quality.

Description

technical field [0001] The invention relates to a photoelectric device and its components, in particular to a display device and its filter components, that is, a color filter and a display. Background technique [0002] With the advancement of display technology, people can make their lives more convenient with the assistance of displays. In order to pursue the characteristics of lightness and thinness of displays, flat panel displays (Flat Panel Display, FPD) have become the current mainstream. Among many flat panel displays, Liquid Crystal Display (LCD) has superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. Therefore, LCD is popular among consumers. [0003] Because light-emitting diodes have the advantages of power saving, environmental protection, small size, long life, and fast response speed, etc., light-emitting diodes have gradually become the main backlight source used in li...
