Flexible liquid crystal module and flexible liquid crystal display device

Abstract

The invention provides a flexible liquid crystal module. The flexible liquid crystal module comprises a back plate, LED light strips, light guide plates and diffusion plates, wherein the LED light strips, the light guide plates and the diffusion plate are sequentially arranged on the back plate; the upper surface of each light guide plate is planar, the lower surface of each light guide plate is curved, each light guide plate is divided into multiple array modules in a horizontal direction, each light guide plate facing the vertical direction of the LED light strips is divided into two plates, the side surfaces of every two light guide plates in the vertical direction are attached to two reflective sheets respectively, a gap is formed between every two adjacent light guide plates, and every two reflective sheets are connected through at least two elastic components; each LED light strip comprises a flexible circuit board, and multiple groups of electric conductors and LED chips which are printed on the flexible circuit board and in parallel connection, and each flexible circuit board is provided with multiple micro-arrays, wherein the heights of the micro-arrays are different, but the arc shapes formed by the micro-arrays are equal to the lower surfaces of the light guide plates. Thus, the expansion and support problems during heating are well solved, the structure is simplified, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of flexible liquid crystal displays, and more specifically relates to a flexible liquid crystal module and a flexible liquid crystal display device. Background technique [0002] Flexible liquid crystal module is a component that provides light source for flexible liquid crystal display products, and is one of its key components. Large-size flexible liquid crystal modules have been widely used in many aspects such as computer flexible liquid crystal displays, liquid crystal TVs, and flat outdoor advertisements. The flexible liquid crystal module is arranged under the flexible liquid crystal display to provide evenly diffused light with a certain brightness to the flexible liquid crystal display. By controlling the pixel electrodes on the flexible liquid crystal display, different brightness, different colors and different gray scales can be formed. Color screen. According to the position of the light source, the flex...

AI Technical Summary

Problems solved by technology

Because the thickness of the light guide plate decreases, its thermal expansion and moisture absorption expansion characteristics gradually become prominent. At the beginning, the light guide plate is fixed, and after being heated or absorbing moisture, it will expand, which will deform due to extrusion, which will greatly affect the quality of light. ; At the same time, when the light guide plate expands, the light guide plate may come into contact with the LED light bar

In addition, when heated or expanded due to moisture absorption, because the flexible liquid crystal module is curved, the support for the light guide plate is either very complicated, such as a plastic frame with a complex shape, or the satisfaction of the expanded light guide plate cannot be achieved. effect support
