Abstract

The invention discloses a display panel and a display device. Display areas of the display panel comprise a first area and a second area, wherein the quantity of pixel units in each row in the first area is smaller than the quantity of pixel units in each row in the second area; a scanning line in electrical connection with a first shifting register is positioned in the first area, and a scanningline in electrical connection with a second shifting register is positioned in the second area; the first shifting register and the second shifting register are electrically connected with a first clock signal line; the first shifting register is electrically connected with the first clock signal line by using a resistance compensation unit; or the first shifting register is electrically connectedwith a second clock signal line; the second shifting register is electrically connected with a third clock signal line; an effective signal duty ratio of the second clock signal line is greater thanan effective signal duty ratio of the third clock signal line. According to the technical scheme in the invention, delay time of enabling the first shifting register to output a scanning drive signalto the scanning line positioned in the first area is prolonged, and display uniformity of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] The display panel generally includes a display area for image display and a non-display area for setting peripheral driving circuits. The pixel units arranged in an array in the display area are electrically connected to the driving circuit through switching elements. The current common display panel display The area is generally a regular rectangle, that is, the number of pixel units in each row is basically the same, and the pixel units in a row are simultaneously driven by one scanning line for display. [0003] With the development of display technology and the higher requirements of users for display screens, non-regular special-shaped display screens have appeared one after another, such as a full screen to increase the screen ratio, so that the pixel units in the special-shaped ...
