Problems solved by technology

In this case, the pixels of the special-shaped part of the display area can no longer be arranged in a rectangular array, so the number of pixels in each column is not necessarily the same, so the loads (RC) of different data lines are no longer the same, which leads to the difference between the special-shaped

Embodiment Construction

[0066] In practical applications, a conventional display panel is rectangular, and a plurality of pixels are arranged in a matrix in the display panel, and a gate drive circuit and a source drive circuit are provided in the non-display area of ​​the display panel, and the gate drive circuit provides For scanning signals, the source driving circuit provides data signals for each column of pixels. In a conventional display panel, each data line connects to an equal number of pixels in a column. In the actual manufacturing process, the data line will pass through the non-opening area of ​​a column of pixels, so the resistance of the data line itself, as well as the resistance and capacitance between elements such as transistors in the pixel will become the load of the data line. In order to meet some special requirements, the display panel may be designed into other non-rectangular shapes, then the pixel matrix in the display panel will be cut off a part of the pixels at the edge,...

Abstract

The invention discloses an irregular display panel and a display device. The display panel comprises multiple first fixed potential lines and multiple data lines with incompletely same lengths; a display region is divided into multiple display sub-regions along extension directions of the first fixed potential lines, and at least one data line is arranged in each display sub-region; since the lengths of the data lines in different display sub-regions are incompletely same, the different data line lengths means that the pixel amount connected by the data lines is different, and the data line loads are different; therefore, for compensating the load distance between the data lines, and aiming at different display sub-regions, the shorter the data line in the display sub-region is, the greater of the total overlapping area of the data line in the display sub-region and multiple first fixed potential lines is; the capacitance between each data line and the first fixed potential lines is increased, so that the load of the data with less connected pixel amount is increased, the problem that the display of the display panel is non-uniform is improved, and the display effect is promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a special-shaped 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 di...
