Abstract

The invention discloses an array substrate, a preparation method thereof and a display panel. The array substrate is characterized in that: a passivation layer and an interlayer insulating layer are replaced by a planarization layer; and a source and drain electrode layer and a first electrode layer are combined into a conductive layer, so that a capacitor is directly formed between the first electrode layer and a second active layer. According to the array substrate, the preparation method thereof and the display panel of the invention, two photomasks are saved during preparation of the array substrate. The preparation method has the following advantages that: the preparation process is simplified; resources are saved; and the production efficiency is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display panel. Background technique [0002] With the rapid development of display technology, Organic Light-Emitting Diode (OLED) has become the representative of the new generation of flat display technology due to its advantages of self-illumination, high contrast, thin thickness, wide viewing angle and fast response speed. Among them, the active-matrix organic light emitting diode (Active-Matrix Organic Light Emitting Diode, AMOLED) technology has broad application prospects. [0003] The existing AMOLED display panel mainly includes: a TFT array substrate including a thin film transistor (Thin Film Transistor, TFT) driving circuit, and a plurality of OLED display devices arranged on the TFT array substrate, each of the OLED display devices Controlled by a corresponding TFT. The TFT array substrate of the ...
