Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] One embodiment of the present invention provides a guide film, referring to figure 1 , the guide film in this embodiment includes a transparent substrate layer 1 and a microstructure layer 2 disposed on one side of the transparent substrate layer 1 , that is, the light-emitting surface. The transparent substrate layer 1 is a flat plate structure with a thickness less than or equal to 300 μm. The microstructure layer 2 includes several microstructures 2...

Abstract

The present invention provides a guide film and an LED display screen with the application of the guide film. The guide film comprises a transparent substrate layer and a microstructure layer which is arranged the light out surface of the transparent substrate layer and comprises a plurality of microstructures used for transmitting the incident light which goes through the transparent substrate layer to a particular direction or particular angle, thus the emergent angle of the light of the LED display screen with the application of the guide film can be adjusted, the emergent light is irradiated to a below area as much as possible, and the viewing comfort and brightness of a viewer are improved. Since only the light out surface of the LED of the LED display screen provided by the invention is equipped with the guide film, the fabrication and installation process is relatively simple, and the guide film is suitable for an LED which is subjected to secondary light distribution and an SMD type LED.

Description

technical field [0001] The invention relates to the technical field of semiconductors, and more specifically relates to an orientation film and an LED display screen using the orientation film. Background technique [0002] Currently, display screens using LEDs (Light Emitting Diodes, light emitting diodes) as backlight sources have been widely used in various fields such as stadiums, surveillance, entertainment, and outdoor advertising. Among them, when installing the LED display, in order to prevent the sight of people who are far away from the LED display from being blocked by people who are close to the LED display, the LED display needs to be hung at a relatively high position for the view of the side below it. people watch. However, due to the large light emitting angle of the LED and the uncontrollable projection direction of the LED light, the light emitted to the top of the LED display cannot be received by human eyes, resulting in waste of energy and loss of brigh...
