Abstract

The invention provides an OLED display panel and a manufacturing method thereof. The display panel comprises the following parts of a substrate comprising a color film layer and a first transparent conductive layer, wherein the first transparent conductive layer comprises a first region and a second region, the first region corresponds to a region forming the color film layer, and the second region corresponds to a region forming a gate stack layer; a buffer layer covering the first transparent conductive layer; an active area comprising a first active area and a second active area, wherein the first active area is located above the first region, and the second active area is located above the second region; a gate stack layer located above the second active area; an interlayer dielectriclayer, a second transparent conductive layer, a planarization layer, a color film layer, a second buffer layer, an anode, a pixel defining layer and a light emitting structure.

Description

Technical field [0001] The invention relates to the field of electronic display, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, the development of Organic Light Emitting Diode (OLED) display technology is advancing by leaps and bounds. OLED products have received more and more advantages due to their light and thin, fast response, wide viewing angle, high contrast, and flexibility. The attention and application of the mobile phone are mainly used in the display technology fields such as mobile phones, tablets and TVs. [0003] As the size of the panel increases, the resistance of the signal line becomes non-negligible, resulting in an increase in the voltage drop phenomenon, resulting in uneven brightness of the display panel, and restricting the mass production of large-size OLED display panels. Therefore, it is urgent to solve this problem. Summary of the invention [0004] The ...
