Problems solved by technology

However, this transflective LCD panel is not suitable for electronic reading
Since electronic reading usually only requires black and white images, and when using the semi-transmissive and semi-reflective liquid crystal display panel for electronic reading, since the backlight consumes more power, the energy consumption of electronic products is relatively large, which is not conducive to improving the use of electronic products. lasting value

Embodiment Construction

[0038] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] The display panel in the embodiment of the present invention includes: several pixel units, each pixel unit includes four sub-pixel units arranged in a matrix, each sub-pixel unit has a reflective area and a transmissive area, and the transmissive area is used to display a color image, The reflective area is used to display black and white images. When the display panel is in the transflective mode, because the transmitted light is brighter, the display panel displays a color image, and every four sub-pixel units correspond to one pixel point; when the display image is in the reflective mode, since there is no Transmitted light, only reflected light is emitted from the reflective area. The display panel displays black and white ...

Abstract

The invention discloses a display panel, which comprises a plurality of pixel units, wherein each pixel unit comprises four sub-pixel units which are arranged in a matrix form; each sub-pixel unit is provided with a reflecting area and a transmission area; the transmission area is used for displaying a color image; and the reflecting area is used for displaying a black-white image. When the display panel is in a half reflecting and half transmitting mode, the transmission light is brighter, so that the display panel displays the color image, and four sub-pixel units form one pixel; and when the display image is in a reflecting mode, transmission light is unavailable, and only reflected light is emitted from the reflecting area, so that the display panel displays a black-white image, one sub-pixel unit constructs one pixel during when the black-white image is displayed, and the resolution of the display panel in the reflecting mode is increased by four times compared with the display panel in the half reflecting and half transmitting mode.

Description

technical field [0001] The present invention relates to the field of displays, in particular to a display panel capable of providing both a semi-reflective and semi-transmissive mode and a high-resolution reflective mode, a display device and a driving method for the display device. Background technique [0002] Liquid crystal display panels have been widely used in electronic devices with display functions, such as computers, televisions, mobile phones, and tablet computers. Existing liquid crystal display panels are mainly divided into three categories: transmissive mode, reflective mode, and transflective mode. Among them, since the semi-transmissive and semi-reflective liquid crystal display panel can be used under the conditions of sufficient light or insufficient light at the same time, the application range is relatively wide. [0003] Please refer to figure 1 , is a schematic cross-sectional structure diagram of a transflective liquid crystal display panel in the p...
