Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses a display panel and a preparation method therefor. The display panel comprises subpixels, and each subpixel comprises a drive transistor which comprises a gate medium layer. Each subpixel also comprises a storage capacitor which comprises a capacitor medium layer; a first insulating layer which is disposed between a data line of the display panel and a scanning line of a display panel; and a second insulating layer which is disposed between the data line and a common line of the display panel. The gate medium layer, the first insulating layer, the capacitor medium layer and the second insulating layer are integrated through a halftone mask or the gray scale masking technology to form insulating films with different thicknesses. The thickness of the gate medium layer is less than the thickness of the first insulating layer. The technical scheme of the invention improves the performance of the display panel.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a manufacturing method of the display panel. Background technique [0002] As the resolution and scanning frequency of the display panel increase, the overall load also continues to increase, which in turn leads to an increase in the power consumption of the display panel and a decrease in its service life. The overall load of the display panel is related to its parasitic capacitance. The parasitic capacitance includes the capacitance generated between the data line and the scan line of the display panel. By increasing the thickness of the insulating layer between the data line and the scan line, the parasitic capacitance can be reduced. However, in order to save the process flow of the display panel, the gate dielectric layer in the display panel driving transistor is formed integrally with the insulating layer in a one-step process. The increase in the t...
