Abstract

The invention provides a display panel. The display panel comprises thin film transistors arranged in an array mode. The source electrodes and the drain electrodes of the thin film transistors comprise electrode layers, and the electrode layers of the source electrodes or the drain electrodes extend to pixel opening areas and can serve as pixel electrodes. Dielectric layers used for arranging thepixel electrodes are reduced. Compared with the prior art, the display panel has the advantages that photomask manufacturing procedures can be reduced, and cost is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a preparation method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) displays are gradually becoming the mainstream of the display industry due to their advantages of wide viewing angle, high color gamut, and low power consumption. [0003] Currently, TFT (Thin Film Transistor, thin film transistor) whose channel layer is made of metal oxide semiconductor has been widely used in OLED display panels, and top-gate TFT has become the industry's first choice due to its small parasitic capacitance. However, the preparation of the array substrate of the top-gate TFT requires many photomask processes. The current technology requires 8 or more photomasks, and the cost is relatively high. [0004] To sum up, in the prior art OLED display panel manufacturing process, the number of photomasks is large, which is not conducive to saving the pro...
