LASER BACKLIGHT PLATE

摘要

A laser backlight plate includes a laser source, a light guide plate, least one reflective layer, and at least one light divergent structure. The laser source is configured for providing a laser beam. The light guide plate has a light emission surface, a backlight surface, and at least one side surface. The backlight surface is disposed opposite to the light emission surface, and the side surface extends between the light emission surface and the back light surface. The reflective layer at least partially covers the backlight surface and the side surface, and is configured for reflecting the laser beam impinging on the reflective layer to the light emission surface. The light divergent structure is configured for diffusing the laser beam, which is incident on the light guide plate from the light divergent structure, and is reflected to the light emission surface by the reflective layer.
