Problems solved by technology

Due to the difference in pixel distribution density between the transparent display area and the non-transparent display area, the load on each signal line in the transparent display area is relatively reduced, resulting in the display split screen problem

Abstract

The invention discloses a display panel and a display device. Since the pixel distribution density in the first display area is smaller than the pixel distribution density in the second display area, that is, the number of pixels connected to the first signal line is smaller than the number of pixels connected to the second signal line. The number of connected pixels decreases, which means that the load of the first signal line is lower than the load of the second signal line. Therefore, in order to compensate the load difference between the first signal line and the second signal line, a load compensation unit is set in the first display area for each first signal line, and the more pixels connected to the first signal line, the greater the load The smaller the compensation value of the compensation unit, the higher the load of the first signal line connected to the less number of pixels, the problem of split-screen display of the display panel is improved, and the display effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The commonly used display panels at the present stage can generally be divided into a display area for image display and a non-display area for setting peripheral driving circuits and the like. The pixels distributed in an array in the display area are respectively connected to the driving circuit in the non-display area through a switch element. Usually, each switching element is connected to a scanning line and a data line, the switching element is turned on by receiving the scanning signal of the scanning line, and the pixel is driven to display a certain gray scale by receiving the data signal of the data line. The switching elements are connected to scan lines and data lines in different combinations, so that each pixel can emit light independently. Currently, the display areas of common display panels ar...
