Abstract

The embodiment of the invention discloses an OLED display panel, which comprises a first substrate, a flat layer, an auxiliary electrode, an anode, a pixel definition layer, a cathode isolation column, an organic light-emitting layer, a cathode and an electrode table, wherein the flat layer is formed on the first substrate; the auxiliary electrode is formed on the first substrate; the anode is formed on the flat layer; the cathode is formed on the organic light-emitting layer and comprises a light-emitting cathode and an isolation cathode; the light-emitting cathode is located on the pixel definition layer and a pixel region; the isolation cathode is located on the cathode isolation column; the light-emitting cathode is separated from the isolation cathode through the cathode isolation column; the electrode table is electrically connected with the auxiliary electrode directly or indirectly; the cathode isolation column is formed on the electrode table; and the electrode table is electrically connected with the light-emitting cathode for the light-emitting cathode to receive voltage on the auxiliary electrode. The embodiment of the invention further discloses a manufacturing methodof the OLED display panel. The OLED display panel has the advantage that the cathode is electrically connected with the auxiliary electrode stably.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display panels are favored by people because of their thinness, energy saving, wide viewing angle, wide color gamut, and high contrast. Display, but also gradually develop to large size. However, due to the large size of the OLED display panel, there is a problem of IR Drop, that is, the problem of voltage drop in the long-distance transmission of voltage, resulting in visually visible Mura (uneven display). To improve this issue, see see figure 1 In the OLED display panel, the auxiliary electrode 121 and the cathode isolation column 150 are produced in the process, and the cathode 146 is isolated by the cathode isolation column 150 so as to achieve independent control of the cathode 146 and reduce the problem of IR Drop. [0003] However, in the OLED di...
