Problems solved by technology

The display panel shown in the figure is divided into a display area and a bending area, wherein the bending area part is composed of a plurality of bending-resistant members (not shown in the figure), but these bending-resistant members cannot play a display role, that is, the bending area are not displayed
In addition, when realizing dynamic bending of OLED displays (such as 180° bending), it should also ensure that it will not fail for a long time, otherwise it will affect the service life of flexible OLEDs.
Limited by the lifespan of OLED displays, true flexibility has not yet been achieved, at least no mass-produced dynamically bending flexible OLED screens have been formed. Therefore, in a long-term period, flexible OLEDs are still the most promising research direction.

Embodiment Construction

[0022] In order to make the purpose, technical solution and effect of the present application more clear and definite, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0023] The present application provides a bendable flexible substrate, in which a deformation layer made of a shape memory material is provided, and the shape memory performance of the deformation layer can be used to realize dynamic bending of the display panel, and can effectively control the display panel. The panel is bent to a predetermined angle to prevent unnecessary tearing of the panel due to excessive bending, thereby prolonging the life of the display panel. At the same time, various anti-bending components are omitted in the bending area, so that TFTs and pixel units can be normally arranged in the bending area, so that the bending area can also be displayed normally.

[0024] see Figure 4 , Figure 4 It is a structural s...

Abstract

The present application discloses a bendable flexible substrate, a display panel, and a display device. The bendable flexible substrate includes a planar region and a bendable region. One side of the bendable region is provided with a deformable layer. The deformable layer is a shape memory The material and the deformable layer are used to drive the bendable region to bend to a predetermined angle under the action of an external force. Through the above method, the present application can realize the dynamic bending of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a bendable flexible substrate, a display panel and a display device. Background technique [0002] With the development of information transmission technology and electronic products, organic light-emitting diode (Organic Light-Emitting Diode, OLED) display has been widely used because of its advantages of high brightness, fast response, low energy consumption, and low cost. application. Among them, flexible OLED displays are gradually attracting attention, and are generally considered to be the next generation of mainstream displays. [0003] In the long-term research and development process, the inventors of the present application found that OLED panels still have obvious defects, such as a much shorter lifespan than LCD displays, which seriously affects the application of OLED panels. In particular, the application of flexible OLED displays is still limited to th...
