Problems solved by technology

like figure 1 As shown, the light 2 emitted by the light source 1 passes through the light guide plate 3 and the microstructure 4 on it, and due to the interface refraction and reflection, it is divided into two light rays 2A and 2B, wherein the light 2A is provided to the display panel 5. light source, and the light 2B directly exits the display module, resulting in a waste of light energy. In this way, the light energy provided by the light source cannot be effectively output as the display light 2C, and the contrast and clarity of this display module are reduced.

Embodiment Construction

[0047] The invention provides a flexible display device. In a preferred embodiment, the flexible display device of the present invention is applied to various flat displays, such as liquid crystal displays, electronic paper and other products.

[0048] figure 2 It is a cross-sectional view of an embodiment of the flexible display device of the present invention. Such as figure 2 As shown, the display device includes a display panel 10 , a light source module 20 and an optical structure film 30 . In this preferred embodiment, the display panel 10 is an electrophoretic display panel. The more common electrophoretic display panels use countless microcapsules stored in a transparent liquid medium to display black and white colors. Each microcapsule is composed of two hemispheres of black and white. The change of these microcapsule balls controls the rotation of these microcapsule balls, so that under the irradiation of external light, the text or image to be displayed is pre...

Abstract

The invention provides a flexible display device. The flexible display device comprises a display panel, a light source module and an optical structure film, wherein the display panel is provided with a light entering surface; the light source module and the display panel are parallelly arranged, and the light source module comprises a light guide plate with an light emitting surface; the light emitting surface faces the light entering surface, and light rays generated by the light source module are projected to the light entering surface from the light emitting surface; the optical structure film is arranged between the display panel and the light source module and is provided with a first surface and a second surface opposite to the first surface; a plurality of platform-shaped optical structures with platform top surfaces are formed on the first surface; and a first translucent glue layer and a second translucent glue layer are formed on the light entering surface and the light emitting surface respectively, the platform top surfaces are glued with one translucent glue, and the second surface is glued with the other translucent glue layer. The structure strengthens the joint between the display panel and the light source module, ensures the excellent flexibility of the whole display device, removes air gaps between the display panel and the light source module and improves the light energy utilization rate.

Description

technical field [0001] The present invention relates to a display device; specifically, the present invention relates to a display device with better flexibility. Background technique [0002] Compared with a traditional cathode ray tube (CRT) display, a flat panel display (FPD) has the advantages of smaller volume and less power consumption. Therefore, in the current trend of focusing on thinner, lighter and smaller volumes in the design of electronic equipment, flat panel displays have gradually replaced traditional CRTs and become the mainstream products in the display market in the 21st century. [0003] There are various types of flat panel displays, among which liquid crystal displays using liquid crystal display (Liquid Crystal Display, LCD) technology are relatively mainstream products at present, and are widely used in the market. In addition to computer monitors, LCD TVs are becoming more and more popular. In addition, products such as electronic paper (Electronic...
