Color film substrate, manufacturing method thereof and display device

Abstract

The embodiment of the invention provides a color film substrate, a manufacturing method thereof and a display device, which relate to the technical field of display and can be used for increasing the brightness of the display device, reducing the production complexity and the production cost of the display device and reducing the thickness of the display device. The color film substrate comprises a substrate and a color film which is formed on the surface at a light inlet side of the substrate, the color substrate is provided with at least one continuous light refraction structure, the one light refraction structure corresponds to one group of display view field, the group of the display view field comprises a left eye view field and a right eye view field, light emitted by the left eye view field can be emitted into a left eye view area after passing through the light refraction structure corresponding to the left eye view field, and the light emitted by the right eye view field can be emitted into a right eye view area after passing through the light refraction structure corresponding to the right eye view field. The color film substrate disclosed by the embodiment of the invention is used for manufacturing a display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method thereof, and a display device. Background technique [0002] Stereoscopic image display technology is also called three-dimensional image display technology or 3D (Three Dimensions, three-dimensional graphics) display technology. This technology is dedicated to fully reproducing the three-dimensional information of objective images and displaying stereoscopic images with a sense of depth. The viewer can directly distinguish the distance, depth and other relationships of the scene in the image by watching the 3D image, as if they are personally on the scene, and can obtain a strong visual impact. [0003] At present, 3D stereoscopic display technology has begun to attract more and more people's attention, and has gradually become one of the high-tech related to national economic development and national defense security. 3...

Problems solved by technology

3D stereoscopic display technology can be divided into two types: vision-aided 3D display and naked-eye 3D display according to the implementation method. Among them, vision-aided 3D display refers to the display method in which the 3D display effect can only be seen with the help of vision-aided equipment such as 3D glasses or helmets. 3D display technology is easy to implement, and most of the current 3D displays use vision-aided 3D display technology, but vision-aided 3D displays require viewers to wear vision-aided glasses or helmets to watch, which brings great inconvenience to viewers

However, the disadvantage of using slit gratings to make 3D displays is that the slit gratings are generally composed of light-transmitting white stripes and opaque black stripes. The black stripes of the slit gratings will block part of the light from exiting, thereby cause the brightness of the display to decrease

Compared with the slit grating, the lenticular lens grating is made of transparent material, so it does not block the exit of light, but the production cost of such a lenticular lens grating is high, and it needs to be additionally formed on the color filter substrate. Will greatly increase the production complexity of 3D displays, thus further increasing the production cost
