DOUBLE-SIDED DISPLAY MODULE WITH OPTICALLY FUNCTIONAL FILM

摘要

A double-sided display module with two optically functional films includes a double-sided display panels, a lighting module, and a display controller. The double-sides display panel includes two oppositely disposed display panels, a light guide module, and two optically functional films. Each of the optically functional films includes a first transformation layer, a second transformation layer, a diffusion layer, a brightness enhancement layer, and a polarized layer, and each layer of the optically functional film is attached to each other by transfer-coating process. Therefore, the thickness of the optically functional film can be reduced, so that the cost of manufacturing the double-sided display module with the optically functional films is saved and the volume of the double-sided display module is reduced as well without reducing brightness.

1. A double-sided display module with optically functional films, comprising:
a double-sided display, comprising:
a first display panel;a first optically functional film with a thickness from 0.4 mm to 1.4 mm, the first optically functional film deposited on the first display panel;a light guide module deposited on the first optically functional film;a second optically functional film with a thickness from 0.4 mm to 1.4 mm, the second optically functional film deposited on the light guide module; anda second display panel deposited on the second optically functional film; a lighting module deposited at one side of the double-sided display, the lighting module configured to emit point light to the light guide module of the double-sided display; and a display controller electrically coupled to the first display panel and the second display panel of the double-sided display, the display controller outputting power and signal to the double-sided display;wherein the first optically functional film and the second optically functional film respectively comprise:
a first conversion layer having an upper surface of a prism structure and a flat bottom surface, the first conversion layer configured to convert point light into linear light and output the linear light; a second conversion layer having an upper surface of a prism structure and a flat bottom surface, the second conversion layer deposited onto the first conversion layer and configured to convert the linear light from the first conversion layer into area light and output the area light; and a diffusion layer having a flat upper surface and a flat bottom surface, the diffusion layer deposited onto the second conversion layer and configured to homogenize the area light from the second conversion layer;and wherein both the first optically functional film and the second optically functional film are respectively attached to the light guide module with the first conversion layer;and wherein display screen direction of the first display panel differs 180 degrees from display screen direction of the second display panel.
