Display substrate and manufacturing method thereof, display panel and electronic equipment

Abstract

The embodiment of the invention provides a display substrate and a manufacturing method thereof, a display panel and electronic equipment, and belongs to the technical field of display. The display substrate comprises a flexible substrate and at least two sub-pixels arranged on the flexible substrate, wherein at least two sub-pixels are arranged in rows and columns, and each sub-pixel comprises adriving circuit and a light-emitting element; the film layer where the driving circuit is located comprises at least one inorganic layer arranged on the flexible substrate, a spacing area is arrangedbetween the driving circuits of at least part of the adjacent sub-pixels, and the inorganic layer is provided with a groove in the spacing area. The display substrate also comprises an organic layer,wherein the organic layer is filled in the trench. According to the embodiment of the invention, the spacer regions are arranged between the inorganic layer driving circuits of the display substrate,and the inorganic layers in the spacer regions are replaced with the organic layers, so the bending radius of the display substrate can be reduced, and the bending reliability of the display substrateis improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display substrate and a manufacturing method thereof, a display panel and electronic equipment. Background technique [0002] At present, the development of mobile phone screens is changing with each passing day. The screen form has transitioned from the earliest straight display to a full screen, and has been upgraded to a double-sided fixed curvature screen, a four-sided fixed curvature screen, and an inverted button screen. But these product screens cannot be physically changed. The emergence of foldable screens has increased the way the screen changes in a certain sense, but foldable screens can only be folded in a fixed area at present, and the folding method is still relatively single. [0003] Such as figure 1 As shown, the foldable screen is generally designed as a fixed curvature area 101 and a foldable area 102, which can realize the expan...

AI Technical Summary

Problems solved by technology

[0006] Embodiments of the present invention provide a display substrate and its manufacturing method, a display panel, and electronic equipment, which can solve the problem that the existing rollable screen tends to cause the inorganic film layer to break when it is bent, which in turn causes the metal film layer to break and affect the display.
