Flexible liquid crystal module and flexible liquid crystal display device

Abstract

The invention provides a flexible liquid crystal module, comprising: a back plate, an LED light bar, a light guide plate and a diffusion plate arranged on the back plate in sequence; the upper surface of the light guide plate is a plane, the lower surface is a curved surface, and the light guide plate is horizontal The direction is divided into multiple array modules, and it is divided into two pieces in the vertical direction towards the LED light bar. Two reflective sheets are respectively pasted on the sides of the two light guide plates in the vertical direction, and a gap is formed between two adjacent light guide plates. In the gap, the two reflectors are connected by at least two elastic components; the LED light strip includes a flexible circuit board and multiple sets of parallel electrical wires and LED chips printed on the flexible circuit board, and the flexible circuit board also has multiple microarrays. The heights of the microarrays are unequal, and the arc shape formed is the same as the lower surface of the light guide plate, which solves the problem of expansion and support when heated, simplifies the structure, and saves the cost.

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
