Abstract

An embodiment of the present application provides a display panel and a display device, including: a display area and a non-display area surrounding the display area; the display area includes a semi-transparent display area and a normal display area surrounding the semi-transparent display area on at least three sides area; the translucent display area includes a first sub-pixel and a first pixel drive circuit for driving the first sub-pixel to emit light, the first pixel drive circuit includes a first drive transistor made of an oxide semiconductor, and the first pixel drive circuit is used for for generating driving current; the normal display area includes a second sub-pixel and a second pixel driving circuit for driving the second sub-pixel to emit light; the second pixel driving circuit can compensate the drift of the threshold voltage. The present application uses transistors made of oxide semiconductors with good stability in the semi-transparent display area, which avoids the problem of too many transistors and signal lines caused by the need for threshold compensation function due to the deviation of the threshold voltage of the transistors. Therefore, the light transmittance of the translucent display area is increased.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] With consumption upgrades, consumers' demand for display panels has further increased. Consumers require that the visible area (display area) of the display panel accounts for an increasing percentage of the entire display panel area. For example, in products such as mobile phones, the display panel needs to set up a special area for the conduction of light such as camera modules, light sensors, optical fingerprint recognition modules, dot matrix light sensors, and iris recognition sensors. Therefore, in the existing display panel, holes and slots are made on the display panel to place these devices. However, this will result in a decrease in the screen-to-body ratio of the display panel, and it does not conform to the symmetrical aesthetic design. 【Content of invention】 [0003] In view of this...
