Abstract

An embodiment of the present invention provides a display panel and a display device, including a display area and a peripheral area, the peripheral area includes at least one rounded corner area, and at least one dummy driving unit is located in the rounded corner area and between two gate driving units . The output end of the gate drive unit is electrically connected to the gate line, the first clock signal input end of the gate drive unit is electrically connected to the first clock signal line, and the second clock signal input end of the gate drive unit is electrically connected to the second clock signal Wire connection. The output end of the dummy driving unit is insulated from the gate line, and the first clock signal input end of the dummy driving unit and the second clock signal input end of the dummy driving unit are both insulated from the first clock signal line and the second clock signal line. The display panel and the display device provided by the embodiments of the present invention can maintain the etching uniformity of the rounded corner area by arranging a virtual driving unit between the gate driving units in the rounded corner area, and improve the reliability and good quality of the display panel and the display device. Rate.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] With the application of display technology in smart wearables and other portable electronic devices, the design of electronic products is constantly pursuing the user's smooth user experience. At the same time, it is also increasingly pursuing the user's sensory experience, such as: wide viewing angle, high resolution Features such as high power efficiency, narrow bezels, and high screen-to-body ratio have become the selling points of various electronic products. [0003] In order to further increase the screen-to-body ratio of existing electronic products and continuously improve the use of the space around the camera and earpiece, various design schemes such as "left-sea screen", "non-rectangular screen" and "hole-digging screen" have appeared. As a result, there are many rounded corner areas on the display screen,...
