Abstract

The invention discloses an OLED display panel and an OLED display device with the OLED display panel, and relates to the technical field of electroluminescent display. The problems that in the box alignment process of an existing top emitting type OLED display panel, pressure is too large, and an auxiliary electrode and a cathode are prone to being in a short circuit are solved. The OLED display panel comprises an array substrate and a color film substrate, the array substrate is covered with the cathode, the auxiliary electrode is formed on the color film substrate, a contact structure arranged between the color film substrate and the array substrate is further included, the contact structure enables the cathode and the auxiliary electrode to be electrically connected, and the area of the contact position of the contact structure and the array substrate is larger than or equal to the area of the contact position of the auxiliary electrode and the contact structure. The LED display device with the OLED display panel is further provided.

Description

technical field [0001] The invention relates to electroluminescence display, in particular to an OLED display panel and an OLED display device using the same. Background technique [0002] Among flat panel display panels, OLED (Organic Light Emitting Display, Organic Light Emitting Diode) display panel has attracted widespread attention due to its advantages such as self-illumination, fast response, wide viewing angle, high brightness, bright color, and thinness. [0003] According to different light-emitting surfaces, OLED display panels can be divided into two types: top emission and bottom emission. figure 1 The structure of a pixel in a top emission OLED display panel is shown, including an array substrate and a color filter substrate, and the array substrate includes a thin film transistor device layer formed on a first substrate 101 ( figure 1 Not shown in ), anode 103 , pixel defining layer 104 , light emitting layer 105 and cathode 106 , the color filter substrate i...
