Abstract
An exemplary billboard includes a backlight module, a light transmissive canvas, a pattern layer and a light converging layer. The light transmissive canvas is adjacent to the backlight module. The light transmissive canvas includes a first surface facing the backlight module and a second surface opposite to the first surface. The pattern layer is formed on the second surface. The light converging layer covers the pattern layer and comprises a plurality of microstructures formed thereon distal from the light transmissive canvas.
Claims10
A billboard, comprising:
- a backlight module;
- a light transmissive canvas adjacent to the backlight module, comprising a first surface facing the backlight module and a second surface opposite to the first surface;
- a pattern layer formed on the second surface;
- and
- a light converging layer covering the pattern layer, the light converging layer comprising a plurality of microstructures formed on a surface thereof distal from the light transmissive canvas;
- wherein the backlight module is configured for illuminating the light transmissive canvas, the pattern layer is configured for bearing graphical content, and the light converging layer is configured for converging light emitted from the backlight module and protecting the pattern layer.
A process for manufacturing a billboard, comprising:
- providing a light transmissive canvas having a first surface and a second surface opposite to the first surface, the second surface having a pattern layer formed thereon;
- forming a coating on the second surface to cover the pattern layer;
- forming a plurality of microstructures on a surface of the coating distal from the light transmissive canvas and solidifying the coating via ultraviolet;
- arranging the light transmissive canvas adjacent to a backlight module with the first surface facing a light-emitting surface of the backlight module.
