Embodiment Construction

[0037] In order to solve the above technical problems, embodiments of the present invention provide a display device and a method for manufacturing an optical film therein. A display device provided by an embodiment of the present invention includes a display panel, a plurality of sub-pixels disposed in a matrix on the display panel, and an optical film disposed on the light-emitting side of the display panel; the body of the optical film is provided with multiple pixels distributed in a matrix. A group of hole structures; each group of hole structures corresponds to a sub-pixel setting; wherein, each group of hole structures has through holes that are inclined in the same direction relative to the plane of the optical film body, and the openings of the through holes gradually increase from the light-incoming side to the light-outgoing side , on a section along the side of the display device and perpendicular to the main body of the optical film, the angle between the first sid...

Abstract

The embodiment of the invention discloses a display panel and a preparing method of optical film of the display panel. In the scheme, because a body of the optical film is provided with hole structures of through holes with identical tilting direction, and all the hole structures comprise at least two tilting directions, the direction of light of corresponding sub-pixels can be controlled by combining the tilting direction and the shape of the through holes and the refractive index of the body of the optical film, a good light split effect is achieved, and the problem that a big viewing angle is poor in impression is improved; meanwhile, if the display panel is subjected to dividing and display with regard with left and right eyes, a good naked eye 3D and double vision effect can be achieved; in addition, the optical film is simple in structure, and the corresponding technology is simple.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a method for preparing an optical film therein. Background technique [0002] At present, most display devices are flat panel displays, and TFT-LCD panels and OLED panels are widely used in the field of flat panel displays due to their good viewing angle and lower power consumption. [0003] The current display devices all have the phenomenon of low brightness or low contrast ratio (Contrast Ratio, CR) at the side viewing angle. Different optical films can be used to disperse the light at the middle viewing angle to both sides through the refraction of light, which can be well improved. The phenomenon of poor viewing angles on both sides has gradually improved the phenomenon of poor viewing angles of current display products. However, the optical films currently used are difficult to control the direction of light propagation, and the problem of poor percep...
