Mask and preparation method thereof, color film substrate and preparation method thereof as well as naked-eye 3D (three dimensional) display device and application

Abstract

The invention relates to the technical field of display and discloses a mask and a preparation method thereof, a color film substrate and a preparation method thereof as well as a naked-eye 3D (three dimensional) display device and application. The mask (101) comprises at least one non-photic zone (102) and at least one photic zone (103), wherein a light-transmitting film with non-uniform light transmittance is arranged in each photic zone (103). The naked-eye three-dimensional display effect can be realized by using the color film substrate prepared by the mask and a display device formed by the color film substrate without addition of a slit grating, so that manufacture procedures are reduced, the manufacturing cost is reduced and reduction of an existing device is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask plate and a preparation method thereof, a color filter substrate and a preparation method thereof, a naked-eye 3D display device and its application. Background technique [0002] Three-dimensional image display technology or 3D (Three Dimensions, three-dimensional graphics) display technology is to completely reproduce the three-dimensional information of the objective image and display a three-dimensional image. One of the characteristics of the human eye is that the distance is larger and the distance is smaller, which can form a three-dimensional effect. Through 3D technology, the viewer can distinguish the distance, depth, etc. of the image, as if empathizing, and it looks very similar to the real world. [0003] With the development of science and technology, 3D display technology is more and more applied to people's life. 3D stereoscopic display technology can be ...

AI Technical Summary

Problems solved by technology

3D stereoscopic display technology can be divided into two types: vision-aided 3D display and naked-eye 3D display. Among them, vision-aided 3D display means that the 3D display effect can only be seen with the help of vision-aided equipment such as 3D glasses or helmets, but the vision-aided 3D display needs to watch The viewer wears 3D glasses to watch, which brings great inconvenience to the viewer

However, the slit grating is added to the screen by adding it, which increases the process

[0006] CN104345544B discloses a mask plate, which solves the problem of large via hole size and can meet the requirements of refined wiring, but the color filter substrate prepared by using the mask plate does not have naked-eye 3D display effect

[0007] To sum up, the mask plates currently on the market are only used as the carrier of the original graphics in the exposure process. Although the graphic information on the mask plate can be transferred to the color filter substrate through the exposure and development process, the current The color filter substrate produced by some masks does not have the naked-eye 3D display effect

The existing naked-eye 3D effect is realized by adding a slit grating, which not only increases the manufacturing process and the thickness of the display device, but also increases the manufacturing cost
