The conventional flexible display panel is generally a TN display or a VA display, in which the long axis of the liquid crystal molecules is perpendicular to the display plane, and the transparent conductive layer on the side of the color film substrate is a whole.

Referring to fig. 8, fig. 8 is a schematic structural diagram of a display device according to an embodiment of the present disclosure.
Referring to fig. 8, the transparent conductive layer 22 is used to electrically connect with the compensation circuit 101.
The transparent conductive layer 22 is a conductive transparent film, and in this embodiment, the transparent conductive layer 22 is specifically an Indium Tin Oxide (ITO) film, which has the advantages of high visible light transmittance, high infrared reflectance, good chemical stability, firm bonding of the glass substrate, scratch resistance, and the like, and is an ideal material for the display panel 100. In other embodiments, other materials can be used for the transparent conductive layer 22, which is not limited in this application.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a transparent conductive layer according to a first embodiment of the present disclosure.
Specifically, the transparent conductive layer 22 includes a plurality of transparent electrodes 221 and a plurality of wires 222, the plurality of transparent electrodes 221 are disposed in an insulating manner, and the plurality of wires 222 are electrically connected to the plurality of transparent electrodes 221 respectively. And the plurality of wires 222 are electrically connected with the compensation circuit 101 respectively; the compensation circuit 101 is used for detecting the bending position of the display panel 100 and performing voltage compensation on the transparent electrode 221 at the bending position. It is understood that the transparent conductive layer 22 may not include the plurality of traces 222, and the transparent conductive layer 22 may be disposed on another layer as long as the plurality of transparent electrodes 221 can be electrically connected to the compensation circuit 101.
The compensation circuit 101 is configured to apply the same voltage to the plurality of transparent electrodes 221 when the display panel 100 is not bent, and to apply different voltages to the transparent electrodes 221 at the bent position and the transparent electrodes 221 at the planar position when the display panel 100 is bent.
The preparation method of the transparent conductive layer 22 is not limited. In one embodiment, a continuous ITO layer is deposited on the first substrate 21, and then patterned to form a plurality of transparent electrodes 221 and a plurality of traces 222. The continuous ITO layer is patterned, for example, by a laser cutting or photolithography process. In this embodiment, the transparent conductive layer 22 is prepared by: a mask (not shown) is disposed on one side of the first substrate 21, and the patterned transparent conductive layer 22 is prepared by mask deposition.
As shown in fig. 2, in the first embodiment, the transparent conductive layer 22 is divided into a plurality of strip-shaped transparent electrodes 221, and each strip-shaped transparent electrode 221 is disposed at intervals along the first direction, and each transparent electrode 221 corresponds to a plurality of pixel units.
Specifically, in the present embodiment, the transparent conductive layer 22 is divided into a plurality of stripe-shaped transparent electrodes 221, and the plurality of stripe-shaped transparent electrodes 221 are disposed at intervals along the same direction. The first direction may be a transverse direction, a longitudinal direction or a diagonal direction, which is not limited in this application. A certain gap is formed between each two adjacent transparent electrode strips 221, so that each transparent electrode strip 221 can be used as an independent transparent electrode 221, and the compensation circuit 101 can independently control each transparent electrode strip 221. Preferably, the plurality of stripe-shaped transparent electrodes 221 are identical in size and shape and are disposed at equal intervals. In this embodiment, the transparent conductive layer 22 includes a plurality of strip-shaped transparent electrodes 221 and a plurality of traces 222, that is, the plurality of transparent electrodes 221 and the plurality of traces 222 are disposed on the same film layer.
When the display panel 100 is bent around an axis parallel to the transparent electrode 221, the bent portion 32 may have one or several transparent electrodes 221. The compensation circuit 101 may perform voltage compensation on the transparent electrode 221 of the bending portion 32.
Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a second embodiment of a transparent conductive layer provided in the present application, and fig. 4 is a schematic structural diagram of a bending portion of the transparent conductive layer provided in the present application.
In the second embodiment, the transparent conductive layer 22 is divided into a plurality of block-shaped transparent electrodes 221, and each of the block-shaped transparent electrodes 221 is disposed in a two-dimensional array, and each of the transparent electrodes 221 corresponds to a plurality of pixel units. The number and size of divisions of the transparent conductive layer 22 can be set according to the actual situation.
Specifically, in the present embodiment, the transparent conductive layer 22 is divided into a plurality of block-shaped transparent electrodes 221, and the plurality of block-shaped transparent electrodes 221 are arranged in a plurality of rows and columns, and each block-shaped transparent electrode 221 corresponds to a plurality of pixel units. In order to reduce the gap between the transparent conductive layers 22, in the present embodiment, a transparent insulating layer is used to cover the transparent conductive layers 22, and a plurality of traces 222 are disposed on the surface of the transparent insulating layer away from the transparent conductive layers 22, and each trace 222 is electrically connected to one transparent electrode 221 through a connection hole. That is, the transparent electrodes 221 and the traces 222 are different film layers.
Each block-shaped transparent electrode 221 is individually controlled by the compensation circuit 101, so that voltage compensation can be conveniently performed on each block-shaped transparent electrode 221 individually, and the display effect of the bending part 32 is ensured. When the display panel 100 is bent from any direction, the bent portion 32 may have a plurality of transparent electrodes 221. The compensation circuit 101 may perform voltage compensation on the transparent electrode 221 of the bending portion 32.
As shown in fig. 1, the black matrix 23 is disposed corresponding to the gaps of the plurality of transparent electrodes 221.
Specifically, as shown in fig. 1 to fig. 3, no matter the transparent electrodes 221 are strip-shaped transparent electrodes 221 or block-shaped transparent electrodes 221, a certain distance is provided between the boundaries between two adjacent transparent electrodes 221, in this embodiment, the black matrix is disposed at the boundaries between the transparent electrodes 221, that is, the boundaries between two adjacent transparent electrodes 221 are overlapped with the black matrix 23, so that the size of the opening of the display panel 100 is not changed, and the aperture ratio is not lost.
Referring to fig. 5 and 6, fig. 5 is a schematic diagram illustrating a position of a distance sensor provided in the present application; fig. 6 is a schematic diagram of the arrangement position of the pressure sensor provided in the present application.
The flexible color film substrate 20 further includes a plurality of distance sensors 26 or a plurality of pressure sensors 27, which are electrically connected to the control circuit 10, respectively, and the compensation circuit 101 is configured to detect a bending position of the display panel 100 by detecting a distance change between adjacent distance sensors 26. The pressure sensor 27 is used for detecting the pressure change applied to the display panel 100 to detect the bending position of the display panel 100 and transmit the detected bending position to the compensation circuit 101. A plurality of distance sensors 26 or a plurality of pressure sensors 27 are arranged at intervals on the edge of the first substrate 21 of the flexible color film substrate 20.
Specifically, a plurality of distance sensors 26 are arranged on the edge of the first substrate 21 of the flexible color filter substrate 20, at least one distance sensor 26 is correspondingly arranged on each row of transparent electrodes 221, and at least one distance sensor 26 is correspondingly arranged on each column of transparent electrodes 221. Preferably, one distance sensor 26 is disposed on both sides of each row of the transparent electrodes 221, and one distance sensor 26 is disposed on both sides of each column of the transparent electrodes 221, that is, a plurality of distance sensors 26 are disposed on the periphery of the first substrate 21. In other embodiments, each distance sensor 26 may be disposed corresponding to each transparent electrode 221. When the display panel 100 is bent, the distance between the distance sensors 26 of the bending portions 32 changes, and the compensation circuit 101 can determine the position where the distance changes as the bending position of the display panel 100 according to the distance change, so as to compensate the voltage of the transparent electrode 221 at the bending position to offset the abnormal image when the display panel 100 is bent, thereby ensuring the display effect of the display panel 100.
The specific way for the compensation circuit 101 to individually control each transparent electrode 221 may be: the voltage of the transparent electrode 221 at the bent position is increased or decreased to compensate the transmittance of the transparent electrode 221 at the bent position to be the same as that of the non-bent region.
Similarly, a plurality of pressure sensors 27 may be disposed on the edge of the first substrate 21 of the flexible color filter substrate 20, and the pressure sensors 27 may be disposed in the same manner as the distance sensors 26. When the display panel 100 is bent, the pressure sensor 27 of the bending portion 32 can detect the pressure change, and the compensation circuit 101 can determine the position where the pressure change occurs as the bending position of the display panel 100 according to the pressure change, so as to compensate the voltage of the transparent electrode 221 at the bending position, so as to counteract the image abnormality when the display panel 100 is bent, and ensure the display effect of the display panel 100.
It is understood that the flexible color film substrate 20 may further include other functional layers, which is not limited in this application.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a transparent conductive layer according to a third embodiment of the present disclosure.
In the third embodiment, the compensation circuit 101 is used to detect the bending position of the display panel 100 by detecting the capacitance change between the adjacent transparent electrodes 221. It can be understood that when the display panel 100 is bent, the distance between the adjacent transparent electrodes 221 of the bending portion 32 may change, and thus, the capacitance between the adjacent transparent electrodes 221 of the bending portion 32 may also change. The bending position of the display panel 100 can be detected by detecting the capacitance change between the adjacent transparent electrodes 221.
Further, two adjacent edges of the adjacent transparent electrodes 221 are zigzag-shaped 2211.
Specifically, when two adjacent edges of the adjacent transparent electrodes 221 are arranged in the zigzag shape 2211 from the horizontal shape in the related art, the capacitance between the two transparent electrodes 221 is increased, and the capacitance change is more sensitive, so that the compensation circuit 101 can more easily detect the capacitance change between the two adjacent transparent electrodes 221, and thus when the display panel 100 is bent, the compensation circuit 101 can more easily detect the bending condition and the bending position. So that the compensation circuit 101 can perform voltage compensation on the bent position to make the picture of the display panel 100 reach the same level as the normal position.
When the display panel 100 is bent toward the array substrate 40, the capacitance between the two transparent electrodes 221 becomes large. When the display panel 100 is bent away from the array substrate 40, the capacitance between the two transparent electrodes 221 is reduced. If the capacitance between the transparent electrodes 221 changes, it can be determined that the display panel 100 at the position is bent.
The specific compensation magnitude of the voltage compensation performed by the compensation circuit 101 on the transparent electrode 221 can be obtained through an experimental advance test, and then the specific data of the compensation voltage after the experimental test is stored in the compensation circuit 101. When the display panel 100 is bent, the voltage compensation can be directly performed on the transparent electrode 221 according to the pre-stored compensation data.
Specifically, when the compensation circuit 101 performs a test of the compensation voltage, a corresponding relationship between the bending angle of the display panel 100 and the compensation voltage can be obtained. When the display panel 100 is bent at different angles, the cell thickness of the bent portion 32 is different, and the transmittance of the liquid crystal layer 30 at the bent portion 32 is also different, so that the voltages to be compensated are also different. Therefore, the compensation circuit 101 can first obtain the bending angle of the display panel 100, and then select an appropriate voltage according to the bending angle for compensation. The method of obtaining the bending angle of the display panel 100 is not limited, and the bending angle of the display panel 100 may be obtained by, for example, the pressure sensor 27, the distance sensor 26, or the detection capacitor, or a special angle sensor may be provided on the first substrate 21 to obtain the bending angle of the display panel 100.
By the method for testing the compensation voltage in advance, the bending angle of the display panel 100 can correspond to specific voltage compensation data, and when actual voltage compensation operation is performed subsequently, voltage compensation can be performed directly and correspondingly, so that the operation is convenient, and the compensation is more accurate.
As shown in fig. 8, the present application also provides a display device 300 including: a display panel 100 and a compensation circuit 101, wherein the display panel 100 is the display panel 100 described above, and details thereof are omitted here.

The control circuit 10 is a driving circuit of the display panel and includes a compensation circuit 101. The compensation circuit 101 is configured to apply the same voltage to the plurality of transparent electrodes 221 when the display panel 100 is not bent, and to apply different voltages to the transparent electrodes 221 at the bent position and the transparent electrodes 221 at the planar position when the display panel 100 is bent.
The compensation circuit 101 is used for detecting the bending position of the display panel 100 by detecting the capacitance change between the adjacent transparent electrodes 221; or the compensation circuit 101 is used to detect the bending position of the display panel 100 by detecting the distance change between the adjacent distance sensors 26 or the pressure change received by the pressure sensor 27.
