Abstract

The embodiment of the invention provides a display panel and a pixel driving method, and relates to the technical field of display. The display panel is provided with a first display area and a seconddisplay area, the light transmittance of the second display area is higher than that of the first display area, and a plurality of second scanning signal lines and a plurality of second data signal lines are arranged corresponding to the second display area. The display panel is provided with a pixel drive circuit, the pixel drive circuit comprises a first driving sub-circuit used for driving pixels in a first display area and a second driving sub-circuit used for driving pixels in a second display area, and the second driving sub-circuit is connected with a second scanning signal line and asecond data signal line; and for one display period, under the condition that the scanning signal received by the second driving sub-circuit is at the conduction level, the data signal received by thesecond driving sub-circuit is converted into the conduction level from the cut-off level. By means of the technical scheme, at least part of the area of the display panel can be pervious to light andcan be displayed.

Description

technical field [0001] The invention belongs to the field of display technology, in particular to a display panel and a pixel driving method. Background technique [0002] With the rapid development of display technology, users have higher and higher requirements for screen-to-body ratio, which makes the full-screen display of display devices attract more and more attention from the industry. [0003] In some electronic devices such as mobile phones and tablet computers, it is necessary to integrate photosensitive elements such as front cameras, earpieces, and infrared sensing elements. In the prior art, slots or holes can be made on the display screen so that external light can enter the photosensitive element under the screen through the slots or holes on the screen. However, none of these electronic devices has a true full screen, and cannot display pictures in various areas of the entire screen. For example, the area corresponding to the photosensitive element cannot di...
