Embodiment Construction

[0033] As mentioned in the background technology section, in the prior art, even if the area bound to the control chip on the flexible substrate is bent to the back of the display area through the bending area, the area of ​​the border area is still relatively large, and with the PPI of the flexible display device The higher the height, the larger the bezel area, and the existing narrow bezel design method cannot further realize the narrow bezel.

[0034] The inventor finds that the reason for the above problems is: see figure 1 , figure 1 It is a schematic top view of the flexible substrate in the prior art before it is bent. The flexible display substrate 100 includes a display area (that is, AA area in the figure) 01 and a non-display area 02, such as figure 1 As shown, the non-display area 02 includes the fan-out area 021, the bending area 022, the routing area 023 and the binding area 024. The fan-out area 021 is connected to the display area 01, and various signal lines...

Abstract

The invention provides a flexible display substrate, a flexible display panel and a flexible display device. The flexible display substrate comprises a substrate, wherein the substrate comprises a display region and a non-display region, the non-display region sequentially comprises a bending region, a fan-out region and a binding region along a direction pointing to the non-display region from the display region, namely, a bending region, a fan-out region and a binding region which are included in a frame region of the flexible display substrate provided by the invention, the bending region is arranged among the display region, the fan-out region and the binding region, so that the narrow edge framing process is achieved by bending the bending region, the fan-out region also can be bent to a back surface of a display side of the display substrate by the bending region, the frame region only comprises the bending region and does not comprise the fan-out region, the width of the frame is further reduced compared with the prior art, and the narrow edge framing is further achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display substrate, a flexible display panel and a flexible display device. Background technique [0002] Flexible devices are used more and more widely in modern life. Flexible electronic devices, especially flexible display panels, have attracted more and more attention because of their thinness, bendability, even folding, and good mechanical properties. A flexible display panel is usually fabricated on a flexible carrier. Due to its bending characteristics, it is beneficial to realize a design with narrow borders on all four sides. [0003] In existing flexible displays, in order to increase the screen-to-body ratio of the display area and reduce the edge width below the display area, the area bound to the control chip on the flexible substrate is bent to the back of the display area. That is, the side of the flexible display panel where the control chip i...
