Problems solved by technology

Due to the long distance between the light source and the light incident surface of the optical fiber, most of the light emitted by the light source cannot be vertically incident on the cross-section of the optical fiber, which cannot meet the high brightness and high definition of today's image display. Degree Requirements
Furthermore, the light source used in the prior art is an incandescent bulb, so when the display screen is made large enough, it will also affect the display effect.
In addition, in terms of realizing color, the optical fiber display device in the prior art is mainly realized by coating the light-emitting end of the optical fiber with color paint, and it is difficult to clearly realize the color display of the image.

Abstract

The invention discloses an optical fiber display light source structure of a hollow conical platform structure. One of the upper bottom surface, the side surface and the lower bottom surface of the hollow conical platform structure is formed by a light source, a reflection cover and an optical fiber connecting surface, wherein a light outgoing surface of the light source is arranged towards the optical fiber connecting surface; a reflection surface of the reflection cover is located at the inner side of the side surface; and the optical fiber connecting surface is provided with an optical fiber connecting region which corresponds to the position of the light source and is the same as the light source in size. The invention further discloses an optical fiber display device comprising the optical fiber display light source structure, an optical fiber and a display panel, wherein the optical fiber is provided with a light incoming end and a light outgoing end; the light incoming end of the optical fiber is connected with the optical fiber connecting region of the optical fiber display light source structure; the axial direction of the light incoming end is vertical to the optical fiber connecting surface; and the display panel is connected with the light outgoing end of the optical fiber and is used for displaying an image. The optical fiber display light source structure can more effectively utilize the light source to further clearly display the image.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical fiber display light source structure and an optical fiber display device. Background technique [0002] A fiber optic display device in the prior art includes a display panel, several optical fibers fixed on the display panel, and a light source located on one side of the light incident surface of the several optical fibers. Due to the long distance between the light source and the incident surface of the optical fiber, most of the light emitted by the light source cannot be incident vertically on the cross-section of the optical fiber, thus failing to meet the high brightness and high definition requirements of today's image display. degree requirements. Furthermore, the light source used in the prior art is an incandescent bulb, so when the display screen is made large enough, the display effect will also be affected. In addition, in terms of realizing color, the ...
