Embodiment Construction

[0020] The present invention provides a flexible and foldable display panel, such as figure 1 As shown, the display panel includes: at least two non-folding regions 1, and a folding region 2 located between two adjacent non-folding regions 1, and both sides of the folding region 2 are respectively connected with two adjacent non-folding regions 1 , forming an integrated structure.

[0021] Each of the non-folding regions 1 is provided with a GOA (Gate On Array circuit, array substrate row drive) circuit unit 3, wherein the at least two non-folding regions 1 (that is, all non-folding regions 1 of the display panel) contain the single All the GOA circuit units 3 in the display panel, and the GOA circuit units 3 in the two non-folding regions 1 are electrically connected. Of course, the folding area 2 may not contain the GOA circuit unit 3 .

[0022] Since the GOA circuit unit 3 is only arranged in the non-folding area 1, and the GOA circuit unit 3 is not provided in the foldin...

Abstract

The invention provides a flexible and foldable display panel. The display panel comprises at least two non-folding areas and a folding area which is located between two adjacent non-folding areas, andthe two sides of each folding area are connected with two adjacent non-folding areas to form an integrated structure; GOA circuit units are arranged in all the non-folding areas, wherein the non-folding areas include all GOA circuit units of the display panel, and the GOA circuit units in any two non-folding areas are electrically connected. When the flexible and foldable display panel is bent, the GOA circuit units can be prevented from being injured, and the displaying effect of the display panel is guaranteed.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible and foldable display panel. Background technique [0002] AMOLED (Active Array Organic Light Emitting Diode Display) screens have strong competitiveness in the new era of displays due to their thinness, high contrast, and foldability. Flexible folding technology requires that the performance characteristics of the flexible display device do not drift greatly under the action of stress, that is, the mobility of the thin film transistor in the panel cannot drop too severely, the threshold voltage of the N-type thin film transistor cannot drift to a negative value, and the P-type thin film transistor cannot drift to a negative value. The threshold voltage of the transistor cannot drift to a positive value, and the off current of the thin film transistor cannot be too high. When the flexible display device is bent, it may cause damage to the GOA circuit, and then...
