Problems solved by technology

[0003] However, due to the limitations of the current technological level, the microstructure shapes of the viewing angle improving films on the market are relatively single and regular, which can only improve the angle of the emitted light in a large range, but cannot achieve the angle of the emitted light in a small range. Fine regulation

Abstract

The invention provides an optical film and a display device. The optical film comprises a base material and a plurality of convex parts arranged on the surface of the base material. The convex portion comprises a central plane, a first inclined surface, and a second inclined surface. The central plane is parallel to the surface of the substrate. The first inclined surface is connected with the central plane and is far away from the surface of the base material in a direction far away from the central plane. The second inclined plane is connected between the first inclined plane and the surface of the base material, is located on the side, away from the central plane, of the first inclined plane, and is close to the surface of the base material in a direction away from the central plane. According to the optical film, the light emitting angle can be adjusted more finely, so that the visual angle performance of the display device is optimized.

Description

Technical field [0001] The present application relates to the field of display, in particular, to optical diaphragms and display devices. Background technique [0002] The increased panel size and resolution are the main development directions of Liquid Crystal Display, LCDs and organic Light-Emitting Diode, OLEDs. With the size of the panel and the lifting of the resolution, the large view of the display is getting worse, and the effectiveness of the lighting mode and the device structure is minimized on improving the angle of view. To solve this problem, the industry usually uses an external optical solution to improve the large view of the display. Among them, the most common way is to improve the visual angle of different optical microstructures on the display to improve the purpose of improving the display of the display. [0003] However, due to the restriction of the current process level, the viewing angle used in the market improves the microstructure shape of the membra...
