Abstract

The invention discloses a curvature adjustable composite back board used in a curvature adjustable liquid crystal display device. The composite back board comprises a fixing plate (110), a back board body (120) and at least two stretching and retracting control devices (170), wherein the back board body (120) comprises a middle part (121) fixed to the fixing plate (110), the stretching and retracting control devices (170) are arranged between the back board body (120) and the fixing plate (110) and arranged on the two sides of the middle part (121) respectively, and the distance between the back board body (120) and the fixing plate (110) is controlled through stretching or retracting of the stretching and retracting control devices (170) so that the bending curvature of the back board body (120) can be adjusted. The invention further discloses a curvature adjustable backlight module. The distance between the back board body and the fixing plate is adjusted through stretching or retracting of the stretching and retracting control devices (170) so that the bending curvature of the liquid crystal display device can be adjusted.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a composite backplane and a backlight module with adjustable curvature. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of Flat Panel Display. Among many flat panel displays, Liquid Crystal Display (LCD for short) has high space utilization efficiency and low consumption. Power, no radiation and low electromagnetic interference and many other superior features have become the mainstream of the market. [0003] A liquid crystal display device generally includes a liquid crystal display panel (Liquid Crystal Panel) and a backlight module (Black Light Module, BL for short). Since the liquid crystal display panel itself does not have the characteristic of self-illumination, the backlight module must be arranged under the liquid crystal display panel to provide the...
