Abstract

The invention discloses a display panel, and the display panel comprises a cathode and an auxiliary electrode connected with the cathode through a plurality of contact holes. In the direction from atleast one boundary of the display panel to the center of the display panel, the distribution density of the contact holes is gradually increased, thereby solving the problem of light emitting uniformity of the display panel.

Description

technical field [0001] The present invention relates to the technical field of display panels, in particular to a display panel. Background technique [0002] Traditional OLED adopts vacuum evaporation technology, which can be mass-produced at present. However, this technology requires the use of a fine mask, resulting in low material utilization; in addition, for large-size panels, the preparation process of the mask is full of challenges. In recent years, printing display technology (ink jet printing, Ink jet printing, IJP) develops rapidly. IJP is the best way to achieve large-scale and low-cost production of OLEDs. [0003] At present, there is a problem of voltage drop when IJP display panels are lit, and this problem has a significant impact on the uniformity of light emission. The industry uses auxiliary electrodes to improve this kind of problem. Although this method can improve the light emission of the device compared with the traditional display panel, because ...
