Display substrate and display device

Abstract

The present invention provides a display substrate, which includes a substrate. The substrate comprises a display area and a non-display area configured to surround the display area. The non-display area is provided with a signal line. The display area is provided with a plurality of light-emitting units. A first electrode layer is also arranged above the substrate. The first electrode layer comprises an electrode part and a transmission part. The electrode part is located in the display area and is arranged above the plurality of light-emitting units. The transmission part is located in the non-display area and is arranged on the upper surface of the signal line. The area of the contact part of the signal line with the transmission part is larger than the orthographic projection area of the above contact part on the substrate. Correspondingly, the invention further provides a display device. According to the technical scheme of the invention, the narrow-frame design can be realized, and the IR drop can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) devices are widely used because of their advantages such as self-illumination, rich colors, fast response, wide viewing angle, light weight, thin thickness, low power consumption, and flexible display. It is worth noting that organic electroluminescent display devices made of organic electroluminescent devices also have great application prospects. [0003] figure 1 It is a structural schematic diagram of a display substrate in an existing organic electroluminescent display device, figure 2 Yes figure 1 The schematic diagram of the contact part between the first electrode layer and the signal line, combined with figure 1 and figure 2 As shown, a plurality of light-emitting units 13 are arranged above the substrate, and a plurality of light-emitting units 13 ...

AI Technical Summary

Problems solved by technology

If the width of the signal line 14 is small, it is beneficial to realize the narrow frame, but it will cause the contact area between the first electrode layer 11 and the signal line 14 to be small, and the contact resistance will increase, thereby increasing the IR drop (resistance voltage drop) , increase the power consumption of the display device; if the IR drop is to be reduced, the contact area between the first electrode layer 11 and the signal line 14 must be increased, and since the length of the signal line 14 is constant, the increase in the contact area is It is necessary to increase the width of the signal line 14, so that narrow borders cannot be realized
