Problems solved by technology

[0002] As the demand for AMOLED has been increasing in recent years, the market has higher and higher requirements for its parameters, and brightness is one of the important indicators. Higher requirements, but due to the voltage drop, the brightness of the screen will decrease on the side away from the integrated circuit, which will lead to poor brightness uniformity of the entire screen

Embodiment approach

[0033] method one:

[0034] Such as figure 1 As shown, a luminescent layer 2, a cathode layer 3, a transparent conductive film layer 4, a polarizer 5 and a protective layer 6 are sequentially arranged on the base substrate 1, wherein the transparent conductive film layer 4 is directly formed on the cathode layer 3 and the cathode layer 3 Electrically connected to achieve the effect of reducing the resistance of the cathode layer 3.

[0035] Method 2:

[0036] Such as figure 2 As shown, a light-emitting layer 2, a cathode layer 3, a polarizer 5, a transparent conductive film layer 4, and a protective film layer are sequentially arranged on the substrate 1, and a plurality of via holes are formed on the polarizer 5, and the transparent cathode layer 3 passes through the via holes. It is electrically connected to the cathode layer 3 , and the projection of the via hole on the base substrate 1 is located within the projection of the pixel definition layer on the base substrate...

Abstract

The invention discloses an AMOLED display panel and a preparation method thereof, and relates to the technical field of display. The AMOLED display panel comprises a substrate, a light emitting layerand a cathode layer are arranged at one side of the substrate respectively, the side, far from the substrate, of the cathode layer is provided with a transparent conductive film, and the transparent conductive film is connected with the cathode layer in parallel. Thus, a current channel is enlarged via electrical connection between the transparent conductive film layer and the cathode layer, the cathode resistance is reduced, voltage drop in the side far from an integrated circuit is reduced, and the brightness of the display panel is more uniform.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an AMOLED display panel and a preparation method thereof. Background technique [0002] As the demand for AMOLED has been increasing in recent years, the market has higher and higher requirements for its parameters, and brightness is one of the important indicators. Higher requirements, but due to the voltage drop, the brightness of the screen will decrease on the side away from the integrated circuit, which will lead to poor brightness uniformity of the entire screen. Contents of the invention [0003] The invention provides an AMOLED display panel and a preparation method thereof. In the AMOLED display panel, the channel of the current is expanded by arranging a transparent conductive film layer electrically connected to the cathode layer, which reduces the resistance of the cathode, thereby making it far away from the integrated circuit. The voltage drop on one side is red...
