Problems solved by technology

However, due to the setting of the middle area 1, the number of pixels in a column in the display area adjacent to the middle area 1 in the column direction is less than the number of pixels in a column in the remaining display areas, so that the middle area 1 is adjacent in the column direction The length of the PVDD power traces corresponding to one column in the set display area is different from that of the PVDD power traces in the rest of the display area
Due to the IR Drop (voltage drop) in the PVDD power traces, the PVDD high-voltage signals of the PVDD power traces in one column and the PVDD power traces in the other display areas in the display area adjacent to the middle area 1 in the column direction are different. , resulting in uneven display

Abstract

The invention discloses an organic light-emitting display panel and a display device. Power supply wires extend along a row direction, compensating power supply wires crossed with the power supply wires are arranged, via holes are formed in the junctions of the power supply wires and the compensating power supply wires, and the power supply wires are electrically connected with the corresponding compensating power supply wires through the via holes, so that the power supply wires and the compensating power supply wires in electrical connection realize parallel connection, namely equivalently,the power supply wire is in parallel connection with a resistor, and the resistance of the power supply wire can be reduced. Due to the fact that the larger the quantity of the via holes correspondingto the power supply wires with longer lengths is, the more the resistors in parallel connection with the power supply wires with longer lengths are, the resistance of the power supply wires with different lengths can be the same in an error permissible range, and then IR Drops of the power supply wires with different lengths are the same in the error permissible range, and the display uniformityis improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) is one of the hotspots in the field of flat panel display research. With the development of display technology, the screen of flat panel display is gradually developing into a full screen. The full screen has a large screen-to-body ratio and ultra-narrow borders. Compared with ordinary display screens, the viewer's visual effect can be greatly improved. , which has received extensive attention. In order to achieve full-screen display, such as figure 1 In the schematic structural diagram of the organic light emitting display panel shown, a middle area 1 is generally provided in the display area of ​​the organic light emitting display panel, so that the front camera 11 and the earpiece 12 are arranged in the middle area 1 . However, due to the setting ...
