Abstract
The invention discloses an organic light-emitting display panel and a display device thereof. The non-display area of the organic light-emitting display panel includes a driving chip, the display area includes a first display area and a second display area, and the first display area is located in the second display area and the second display area. between the driving chips; the display area includes a plurality of driving units, the driving units include a first driving unit located in the first display area and a second driving unit located in the second display area; the first source electrode and the first driving unit in the first driving unit The drain electrode is electrically connected to the channel region of the first semiconductor layer through the first connection part; the second source electrode and the second drain electrode in the second driving unit are electrically connected to the channel region of the second semiconductor layer through the second connection part; Wherein, the resistance of the first connection part is greater than the resistance of the second connection part. The present invention solves the problem of uneven display between the first display area and the second display area by setting the resistance of the first connection part in the first display area to be greater than the resistance of the second connection part in the second display area.
Description
technical field [0001] The present invention relates to the field of display technology, and more particularly, to an organic light-emitting display panel and a display device thereof. Background technique [0002] With the rapid development of display technology, large-sized display devices are becoming more and more popular. However, due to the increase in the size of the display device, some display problems caused by it have gradually attracted people's attention. [0003] The display panel of the display device includes a display area and a non-display area arranged around the display area, and pixel units are distributed in an array in the display area. The non-display area includes driving circuits, such as gate driving circuits, source driving circuits, and the like. The power supply signal (VDD) of all pixel units in the display area is provided to each pixel unit by the VDD line of the driving circuit, and the VDD line has a certain resistance. Therefore, the vo...
