Problems solved by technology

[0006] However, in the transflective display panel, a transmissive area and a reflective area are set for each pixel, and in a completely dark environment, the reflective area cannot be displayed using the light generated by the backlight, thus greatly reducing the Panel opening ratio

Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, an opposite substrate and a liquid crystal display layer formed between the array substrate and the opposite substrate. The display panel further comprises a first light actuating unit and a second light actuating unit; the first light actuating unit is used for, in a reflecting mode, reflecting a first part, having a first polarizing direction, of light penetrating the liquid crystal display layer and allowing penetration of a second part having a second polarizing direction, and for in a penetrating mode, reflecting a third part, having a first polarizing direction, of light from a backlight module and allowing penetration of a fourth path having a second polarizing direction; the second light actuating unit is used for, in the reflecting mode, absorbing the second part penetrating the first light actuating unit and for, in the penetrating mode, allowing penetration of the light from the backlight module. The display panel has the advantages that the advantages of the reflecting mode and those of the semi-reflecting and semi-transmitting mode are integrated, and disadvantages of both the reflecting mode and the semi-reflecting and semi-transmitting mode are avoided.

Description

technical field [0001] The invention relates to display technology, in particular to a display panel and a display device. Background technique [0002] With the rapid development of display technology, users have higher and higher requirements for display characteristics, such as high contrast, high resolution, and low power consumption. [0003] In order to meet the requirement of low power consumption, reflective display panels that are more suitable for outdoor work have appeared in the prior art, such as billboards and road signs. [0004] However, the reflective display panel has an obvious disadvantage, that is, it cannot display well when the ambient light is weak. [0005] In order to solve the problem of limited application scenarios of reflective panels, a semi-reflective and transflective display panel is proposed in the prior art. Compared with the reflective display panel, the transflective display panel adds a backlight, so it can also display based on the l...
