Problems solved by technology

[0004] However, the existing double-layer LCD products usually require at least 3 polarizing layers, resulting in low transmittance of the display plane. At the same time, double-layer LCDs usually have high backlight brightness and high power consumption; and the temperature is also high during operation. , has a great influence on TFT characteristics, and is prone to adverse phenomena such as crosstalk and afterimage

Abstract

The invention discloses a display module and a driving method thereof and a display device.The display module comprises a first display panel and a second display panel which are arranged in an up-down stacked mode and further comprises a first polarization layer and a second polarization layer, the first display panel comprises a first upper glass substrate and a first lower glass substrate which are located on the upper surface and the lower surface, the second display panel comprises a second upper glass substrate and a second lower glass substrate which are located on the upper surface and the lower surface, and the first polarization layer is arranged on the upper surface of the first upper glass substrate. The second polarization layer is arranged on the lower surface of the second lower glass substrate or between the first lower glass substrate and the second upper glass substrate. The display module provided by the embodiment of the invention is a double-layer display panel, the display function is realized by adopting the two polarizers, the display panel at the upper layer is used as a main display panel and is a liquid crystal display panel, and the display panel at the lower layer is used for controlling light, so that the contrast ratio of a product can be effectively improved.

Description

technical field [0001] The present application generally relates to the field of display technology, and specifically relates to a display module, a driving method thereof, and a display device. Background technique [0002] With the gradual popularization of liquid crystal displays (Liquid Crystal Displays, LCDs), display technologies compatible with LCDs are also in constant development. [0003] In order to pursue high contrast of the display screen, a double-layer LCD display screen is proposed for LCD products. Due to the superimposed design of the double-layer Cell, the dark part of the screen is darker, thereby improving the contrast of the screen, and the image display is clearer and more visible. Rich in detail. [0004] However, the existing double-layer LCD products usually require at least 3 polarizing layers, resulting in low transmittance of the display plane. At the same time, double-layer LCDs usually have high backlight brightness and high power consumption...
