Problems solved by technology

In the existing special-shaped display panel 20, the number of TFTs connected to the source data lines in the display area corresponding to the left and right sides of the notch 25 is compared with the number of TFTs connected to the source data lines in the display area corresponding to the notch 25. This makes the load (loading) of the source data lines on the left and right sides larger than the load of the source data lines corresponding to the notch 25, resulting in a high probability of uneven brightness in the area near the notch 25. Mura phenomena, such as bright or dark lines appearing at the junction of notch 25, such as figure 2 as shown by the dotted line in

Abstract

The invention provides a special-shaped display panel and display device capable of improving the Mura phenomenon. The special-shaped display panel comprises a display area used for displaying imagesand provided with a notch formed through special-shaped cutting, and a non-display area comprising a surrounding wiring area and a notch area corresponding to the notch of the display area, wherein the display area is divided into several common electrode areas according to the extending of at least one side of the notch area, and at least two of the common electrode areas have different common voltage configurations. The special-shaped display panel and display device can improve the Mura phenomenon and improve the display quality.

Description

technical field [0001] The present application relates to a display technology, in particular to a special-shaped display panel and a display device capable of improving the Mura phenomenon. Background technique [0002] With the development of smart phones and tablets, the screen-to-body ratio is getting bigger and bigger, and it is further developing towards a full screen, and the display screen has also developed from the original rectangular display area to a rectangular display area with a notch. A display panel with such a display area is also called a special-shaped display panel. [0003] figure 1 A schematic diagram of a conventional rectangular display panel 10 is shown. Such as figure 1 As shown, the display panel 10 includes a rectangular display area 11 and a non-display area 12 , and the non-display area 12 includes a peripheral wiring area 121 and a chip 122 . [0004] In the display area 11, the number of thin film transistors (thin film transistor, TFT) ...
