Color filter structure and liquid crystal display panel using the color filter structure

Abstract

A colour filter structure and a liquid crystal display panel using same. The colour filter structure comprises: a transparent substrate (40), colour filter units (44, 44', 44'') formed on the transparent substrate (40), and black matrixes (46) formed around the colour filter units (44, 44', 44''). Lens modules (48, 48', 48'') are arranged corresponding to the colour filter units (44, 44', 44'') on the transparent substrate (40). This colour filter structure and the liquid crystal display panel using same enable light rays emitted from the colour filter units (44, 44', 44'') to be emitted out via the transparent substrate (40) after being refracted by the lens modules (48, 48', 48''), thereby effectively improving the penetration rate, brightness, and visible angle of the liquid crystal display panel.

Description

technical field [0001] The invention relates to the field of plane display, in particular to a color filter structure and a liquid crystal display panel using the color filter structure. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Most of the liquid crystal display devices currently on the market are backlight liquid crystal display devices, which include a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates, control the liquid crystal molecules to change direction by electrifying or not, and refract the light from the backlight module to produce a picture. Since the liquid crystal display panel itself does not emit light, the light source provid...

AI Technical Summary

Problems solved by technology

During the manufacturing process of the liquid crystal display panel, when bonding the TFT base 502 and the CF substrate 504, it is difficult to strictly align the positions of each color filter unit 542 and each pixel electrode 524, resulting in partial light being unable to pass through. Pass the color filter unit 542, and then cause the brightness of the liquid crystal display panel to decrease, which makes the overall brightness of the liquid crystal display device not high

[0005] At present, two methods are mainly used to increase the brightness of the liquid crystal display device. One method is to increase the luminous amount of the backlight source itself in the backlight module, which can be achieved by increasing the LED power or increasing the number of LEDs, but the increase in LED power Larger or larger numbers will lead to increased power consumption and heat generation of the liquid crystal display device, which is not conducive to the improvement of the quality of the liquid crystal display device; another method is to increase the optical film in the backlight module, although this can improve the performance of the liquid crystal display device. Brightness, but it will increase the thickness of the liquid crystal display device, which is not conducive to thinning, and the cost is relatively high, which is not conducive to cost control
