Problems solved by technology

However, when it is applied to a larger-sized display panel, the area of ​​the upper electrode formed by a thin metal layer or a transparent conductive layer needs to be enlarged accordingly, so internal resistance is likely to occur in the far-distance areas on the display panel. The phenomenon of IR drop causes problems in the uniformity of luminous brightness between regions on the display panel, and thus limits the application of organic light-emitting diode displays in large-size display devices.

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a substrate, multiple lower electrodes, a separating layer, multiple light-emitting layers, an upper electrode and at least a first auxiliary electrode. The lower electrodes and the separating layer are arranged on the substrate. The separating layer has multiple pixel region openings and at least one buffer region. The pixel region openings expose the corresponding lower electrodes, respectively. The buffer region is disposed between two adjacent pixel region openings. The light-emitting layers are arranged on the corresponding lower electrodes, respectively. The upper electrode covers the light-emitting layers, the separating layer and the buffer layer. The first auxiliary electrode is provided in the buffer layer.

Description

technical field [0001] The invention relates to a display panel and a manufacturing method thereof, in particular to a display panel with auxiliary electrodes and a manufacturing method thereof. Background technique [0002] Electroluminescent display device (electroluminescent display device) has been expected to replace liquid crystal display and become the next generation due to its characteristics such as no need for color filter, self-illumination (no backlight module required) and low power consumption. Generations of mainstream display technology. Among various electroluminescence displays, an organic light emitting diode display is one of relatively mature technologies at present. [0003] Generally, OLED displays can be classified into top emission OLED displays and bottom emission OLED displays according to their structural design and light emission direction. In the structure of the top-emission organic light-emitting diode display, in order to increase the tran...
