Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as Picture 1-1 As shown, in the related art, the side-lit backlight module 0 is usually used to provide incident light for the display panel A. The side-type backlight module 0 may include a light source 01 and a light guide plate 02, wherein the light guide plate 02 is arranged on the light incident side of the display panel A, the light source 01 is arranged on the side of the light guide plate 02, and the light emitted by the light source 01 can pass through the The side surface of the light plate 02 enters the light guide plate, and exits from the light exit side of the light guide plate 02 , and then enters the display panel A.

[0038] For example, when light is incident from a first medium to a second medium, if the...

Abstract

The invention discloses an optical waveguide display device and a making method thereof, and belongs to the technical field of display. The optical waveguide display device comprises two display substrates formed in an opposite mode, liquid crystals located between the two display substrates and a light source arranged on the side face of the display substrates; the liquid crystals have a first refractive index on the condition that voltage is not applied and have a second refractive index on the condition that the voltage is applied, and the first refractive index, the refractive index of the display substrates and the second refractive index are sequentially increased. According to the optical waveguide display device and the making method thereof, the problem that the mode for controlling subregion glowing is single is solved, and the modes for controlling subregion glowing are enriched and used for the optical waveguide display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical waveguide display device and a manufacturing method thereof. Background technique [0002] The optical waveguide display device may include an array substrate and a cover plate shaped into a box, a filler between the array substrate and the cover plate, and a light source arranged on the sides of the array substrate and the cover plate. The filler can be composed of liquid crystal and high molecular polymer. The refractive index of the liquid crystal when no voltage is applied is different from that when voltage is applied, and is the same as that of the high molecular polymer (greater than that of glass). [0003] The display area of ​​the optical waveguide display device may be composed of multiple sub-areas, and when some of the sub-areas emit light and the other part of the sub-areas do not emit light, the display area can display images. In the related art, the ...
