Display device comprising a light-guide film having a plurality of waveguide parts that have a refractive index

摘要

A display device includes a display panel. A light-guide film is attached to a light-incident surface of the display panel. The light-guide film includes a light reflecting layer, a light exiting layer between the light reflecting layer and the display panel, and waveguide parts situated between the light reflecting layer and the light exiting layer. The light exiting layer has exit openings at positions facing each waveguide part, with each exit opening also facing a sub-pixel unit in the display panel. The display device also includes a light source. An end of each waveguide part is in communication with the light source. The light-guide film replaces a conventional backlight unit such that a thinner design for the display device is possible.

1. A display device comprising:
a display panel; a light-guide film attached to a light-incident surface of the display panel, wherein the light-guide film comprises a light reflecting layer, a light exiting layer between the light reflecting layer and the display panel, and a plurality of waveguide parts between the light reflecting layer and the light exiting layer, wherein the light exiting layer is provided with a plurality of exit openings at positions facing each waveguide part, and wherein each exit opening faces a sub-pixel unit in the display panel; and a light source module, wherein an end of each waveguide part is communicated with the light source module, wherein the waveguide parts have a larger refractive index than the light reflecting layer and the light exiting layer.
