Problems solved by technology

According to the square resistance Rs=resistivity ρ / thickness t, the larger the resistivity ρ value, the larger the square resistance Rs value, which leads to obvious voltage drop in the cathode layer and uneven voltage distribution, which leads to poor uniformity of the display screen , the display effect is not ideal, and for large-size products, the impact is more obvious

Abstract

The invention discloses an organic light-emitting display panel, a display device and a method for manufacturing the display panel. The organic light-emitting display panel includes a display area anda peripheral area surrounding the display area, and includes a base substrate, an organic light emitting unit disposed on the base substrate, and a cathode layer, wherein the cathode layer includes afirst cathode in the display area and a second cathode in the peripheral area, the material conductivity of the second cathode is greater than the material conductivity of the first cathode. According to the scheme of the present application, the contact resistance of the cathode in the peripheral area of the display panel can be reduced, the in-plane voltage drop of the cathode layer can be reduced, and a display effect can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel, a display device and a method for manufacturing the display panel. Background technique [0002] OLED (organic light-emitting diode, organic light-emitting diode) display panel is thin, light, wide viewing angle, active luminescence, continuously adjustable luminous color, low cost, fast response, low energy consumption, low driving voltage, and operating temperature range Wide, simple production process, high luminous efficiency and flexible display and many other advantages, it has been listed as a promising next-generation display technology. [0003] OLED display panels can be classified into PM (Passive Matrix, passive matrix drive) OLED display panels and AM (Active Matrix, active matrix drive) OLED display panels according to different driving methods. An existing organic light-emitting display panel includes an anode, an ...
