Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
An embodiment of the utility model provides a flexible display panel, as shown in fig. 2, can include:
a display element 100 and a driving unit 50 disposed on the first surface a of the flexible substrate 20; the method can also comprise the following steps: a support substrate 200 disposed on a second surface B opposite to the first surface a of the flexible substrate 20; the position of the support substrate 200 corresponds to the binding position C of the driving unit 50.
First, in the embodiment of the present invention, the supporting substrate 200 may be a single-layer substrate, or may be a composite structure composed of at least two layers of substrates. When the driving unit 50 is bound (binding) at the driving unit binding position C of the flexible display panel, the driving unit 50 can be supported by the support substrate 200, thereby avoiding the phenomenon of binding misalignment caused by deformation of the flexible display panel. Therefore, regardless of whether the support substrate 200 is composed of one or more layers, the support substrate 200 should be a hard substrate so that it can have a role of being manufactured. The utility model discloses do not limit to the material that constitutes this stereoplasm base plate.
Second, the display unit 100 may be different according to the type of the flexible display panel. For example:
when the flexible display panel is an organic light-Emitting Diode (OLED), the display unit 100, as shown in fig. 3, may at least include:
a pixel electrode 101, an organic material functional layer 40, and a cathode 102, which are sequentially disposed on the first surface a of the flexible substrate 20. Due to the special material of the organic material functional layer 40, an encapsulation layer (not shown) for encapsulating the organic material must be formed after the display structure is manufactured.
Further, the display unit 100 may further include a Thin film transistor 103 (TFT) between the first surface a of the flexible substrate 20 and the pixel electrode 101. The drain electrode 1031 of the thin film transistor is electrically connected to the pixel electrode 101.
The embodiment of the present invention is described by taking an organic electroluminescent diode as an example for a flexible display panel.
Third, the thin film transistor 103 is a semiconductor unit having a switching characteristic, and may be, for example, an amorphous silicon thin film transistor, a low-temperature polysilicon thin film transistor, an oxide thin film transistor, an organic thin film transistor, or the like, which is not limited herein.
The thin film transistor 103 may be a top gate type or a bottom gate type, and is not limited thereto. Wherein, the top gate and the bottom gate are determined by the positions of the gate and the gate insulating layer, namely: when the gate of the thin film transistor 103 is close to the flexible substrate 20 and the gate insulating layer is far away from the flexible substrate 20, the thin film transistor is a bottom gate thin film transistor, relative to the flexible substrate 20; when the gate electrode is far away from the flexible substrate 20 and the gate insulating layer is close to the flexible substrate 20, the thin film transistor is a top gate type thin film transistor.
Fourth, in the embodiment of the present invention, the driving unit binding position C is disposed on the array structure 30 having the thin film transistor 103. In this way, the driving unit 50 at the driving unit binding position C can input a control signal to the gate line connected to the gate of the thin film transistor 103 to control the thin film transistor 103 to be turned on or off; in addition, the driving unit 50 may input a data signal to a data line connected to the source of the thin film transistor 103 to control the flexible display panel to display.
The driving unit 50 may include a gate driving module and a data line driving module for inputting signals to the gate lines and the data lines, respectively, or the driving unit 50 may be an integrated driving module for inputting signals to the gate lines and the data lines. For example, when the driving unit 50 includes a gate driving module and a data line driving module, two driving bonding locations C need to be disposed on the flexible display panel to correspond to the gate driving module and the data line driving module, respectively, in which case two support substrates 200 need to be disposed on the second surface B of the flexible substrate 20 to correspond to the driving bonding locations C of the gate driving module and the data line driving module, respectively. For another example, when the driving unit 50 is an integrated driving module, only one supporting substrate 200 is required to be disposed on the second surface B of the flexible substrate 20. Of course, the above is merely an illustration of the number of the supporting substrates 200, and other numbers of the supporting substrates 200 are not illustrated here, but all of them should fall within the scope of the present invention.
An embodiment of the utility model provides a flexible display panel, including setting up in the display element and the drive unit of flexible basement first surface, still including setting up in the supporting baseplate on the second surface relative with flexible basement first surface, this supporting baseplate's position and drive unit bind the position corresponding. Therefore, in the process of driving and binding, the driving unit can be supported through the supporting substrate, and the phenomenon of inaccurate binding alignment caused by deformation of the flexible display panel is avoided. Thereby improving the quality of the product.
In the process of manufacturing the flexible display panel, the flexible substrate 20 is first formed on the carrier substrate 10; then, a structure for display, i.e., a display element 100 is formed on the flexible substrate 20 in sequence; next, by using a laser lift-off process, the flexible substrate 20 is irradiated by ultraviolet laser from the side of the carrier substrate 10, so that the adhesive force between the flexible substrate 20 and the carrier substrate 10 is reduced and the flexible substrate is separated from the carrier substrate 10, thereby forming an independent flexible display panel. Finally, a binding process of the driving unit 50 is performed on the flexible display panel.
The supporting substrate 200 is arranged at the binding position C of the driving unit to support the driving unit, so that the phenomenon of inaccurate binding alignment caused by deformation of the flexible display panel is avoided. In order to improve the production efficiency, it is preferable that the support substrate 200 is a glass substrate. That is, when the laser lift-off process is used, the carrier substrate 10 (which may be made of a glass substrate) other than the carrier substrate 10 corresponding to the drive bonding position C is lifted off, and the carrier substrate 10 corresponding to the drive bonding position C is left to constitute the support substrate 200. Therefore, the need for additional manufacturing steps and processes to manufacture the support substrate 200 in other ways can be avoided, and the manufacturing efficiency can be reduced.
Further, as shown in fig. 4, the flexible display panel may further include a first protective layer 300 disposed on the same layer as the supporting substrate 200 and covering the second surface B of the flexible substrate 20 except for the region where the supporting substrate 200 is located.

Thereby improving the processing efficiency and the fabrication accuracy while reducing or eliminating the gap between the first protective layer 300 and the support substrate 200 as much as possible. In addition, the first protective layer 300 can protect the flexible display panel, reduce the difference between the supporting substrate 200 and the flexible substrate 20, make the back surface of the flexible display panel flat, and avoid the damage to the supporting substrate 200 caused by the difference in transportation or use.

the second protective layer 301 is disposed on the same layer as the supporting substrate 200 and covers the second surface B of the flexible substrate 20 except for the region where the supporting substrate 200 and the first protective layer 300 are located.
Among them, the material constituting the second protective layer 301 may include at least: one of epoxy resin and acrylic resin. Since the material is in a flowing state for a while at a normal temperature, after the second surface B of the flexible substrate 20 is covered with the first protective layer 300, the material may be coated on the second surface B of the flexible substrate 20, and the second protective layer 301 may be formed by curing for a while. Due to the fluidity of the above materials, gaps among the first protective layer 300, the supporting substrate 200 and the second protective layer 301 can be avoided, and the exposed area of the second surface B of the flexible substrate 20 is completely eliminated. Thereby protecting the flexible display panel by the first protective layer 300 and the second protective layer 301. In addition, the second protective layer 301 can also reduce the offset between the support substrate 200 and the flexible substrate 20, so that the back surface of the flexible display panel is flat, and damage to the support substrate 200 during transportation or use due to the offset is avoided.
Further, as shown in fig. 5, the flexible display panel may further include a barrier layer 302 disposed on the surface of the display device 100. The barrier layer 302 may be formed of one or more of UV curable glue, polymethylmethacrylate, polyimide, parylene, polyacrylate, and the like. The barrier layer 302 has a water oxygen barrier function capable of blocking permeation of water vapor and oxygen into the display element 100, thereby preventing the water vapor and oxygen from contacting the surface of the display element 100.
