Problems solved by technology

[0002] Generally, the polarizing film used for large-screen display is placed or pasted on the LED device, and then a shading cover (or lampshade, sunshade, isolation cover, etc.) is installed on the polarizing film. The hood is significantly higher than the polarizing film, which reduces the display viewing angle

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings by means of specific embodiments:

[0025] Such as figure 1 As shown, the existing polarizing film 3 for large-screen display is placed or pasted on the LED device 9, the LED device 9 is installed on the PCB board 10, there is a substrate 11 between the LED devices, and then on the polarizing film 3 Install a hood 8 (or lampshade, sunshade, isolation cover, etc.). In this way, due to the location problem of the polarizing film, the light shield is obviously higher than the polarizing film, which reduces the display viewing angle.

[0026] Such as figure 2 Shown is a cross-sectional schematic view of the final drive circuit board with polarizing film placed in the present invention. LED light-emitting device 9 is arranged on PCB board 10. Polarizing film 3 is processed into a concave-convex strip structure by molding machine. Polarizing film 3 is made of conve...

Abstract

The invention discloses a polarized LED display screen based on a polarizing film and a forming method of the polarizing film, comprising a PCB board and an LED light-emitting device, the LED light-emitting device is arranged on the PCB board, wherein the polarizing film is concave-convex The strip structure, the polarizing film is pasted on the PCB board and the LED light-emitting device; the light shield is set on the polarizing film between the two LED light-emitting devices. The invention overcomes the problem that the display viewing angle becomes smaller due to the position of the polarizing film, and the polarizing film is processed into a concave-convex shape, so that the shading cover can be embedded downward, thereby increasing the display viewing angle.

Description

technical field [0001] The invention belongs to the field of electronic display, and in particular relates to a polarization-type LED display screen based on a polarizing film and a forming method of the polarizing film. Background technique [0002] Generally, the polarizing film used for large-screen display is placed or pasted on the LED device, and then a shading cover (or lampshade, sunshade, isolation cover, etc.) is installed on the polarizing film. The light shield is significantly higher than the polarizing film, which reduces the display viewing angle. Contents of the invention [0003] The object of the present invention is to provide a polarizing film-based polarized LED display screen and a forming method of the polarizing film, which overcomes the problem that the display viewing angle becomes smaller due to the position of the polarizing film, and processes the polarizing film into a concave-convex shape, so that the light-shielding The cover can be embedde...
