[0062] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments described in the present application document, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the technical solutions of the present application.

[0063] The terms "first", "second", and the like in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0064] In the related art, in order to realize local refresh in a display panel, in addition to increasing the row refresh circuit, a column refresh circuit also needs to be added. The added column refresh circuit is usually placed below the display area and above the bending area. In this way, the length of the lower frame formed between the lower edge of the display area and the bending line of the bending area will be increased accordingly, thereby causing the length of the lower frame to become longer.

[0065] The preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0066] Referring to Figure 1 , Figure 2 and Figure 3 , a display panel in the embodiment of the present application is proposed, which comprises a bending area and display areas and non-bending areas located on both sides of the bending area.

[0067] The display area comprises at least one column refresh signal line. ​​

[0068] The non-bending region includes: at least one column refresh input line and at least one column refresh circuit, wherein the column refresh input line and the column refresh circuit are coupled one-to-one, and the column refresh circuit is configured to provide a refresh control signal to the column refresh input line in response to a signal at the refresh signal terminal.

[0069] A column refresh input line is coupled to at least one column refresh signal line through a bend.

[0070] In this embodiment, the display panel is divided into a display area, a bending area, and a non-bending area from top to bottom. Typically, the bending area is made of a flexible material, and it can be bent around the bending line (e.g., the horizontal central axis). This creates a bottom border between the lower edge of the display area and the bending line.

[0071] In this embodiment of the application, in order to shorten the length of the lower border, the multiple column refresh input lines coupled to the multiple column refresh signal lines and the multiple column refresh circuits that provide refresh control signals for the column refresh input lines are placed in the non-bending area. In this way, the position of the bending line in the bending area can be moved up accordingly, and the distance between the lower edge of the display area and the bending line will be shortened accordingly, thereby shortening the length of the lower border.

[0072] To implement the column refresh function, the aforementioned display area includes multiple column refresh signal lines. Typically, these column refresh signal lines are matched with the data lines in the display area. (See [link to relevant documentation]). Figure 1 As shown, the column refresh signal lines and data lines are arranged alternately in the display area. The update of the data voltage signal in the data line requires a matching column refresh signal line for control. For example, Figure 1 The updates of data voltage signal 1 in data line 1 and data voltage signal 2 in data line 2 are controlled by the column refresh signal line located between data line 1 and data line 2. In this embodiment, after receiving a valid refresh control signal, the column refresh signal line updates the data voltage signal in the coupled data line, thereby updating the brightness of the corresponding display screen. The refresh control signal is generated by the column refresh circuit. During implementation, the column refresh circuit is configured to provide the refresh control signal to the column refresh input line in response to the signal at the refresh signal terminal. Figure 1 To illustrate, when the refresh signal is valid, the switching transistors T1 and T2 in the column refresh circuit are turned on. The control unit Level Shift in the column refresh circuit generates a refresh control signal under the action of the data voltage signal 1 and data voltage signal 2, and provides the refresh control signal to the column refresh input line. Since the display panel includes pixels, and each pixel includes a pixel driving circuit, the pixel driving circuit can update the data voltage signal under the action of the refresh control signal.

[0073] According to the signal direction of the refresh control signal, one column refresh input line is coupled with at least one column refresh signal line through the bending area, that is, the refresh control signal in the column refresh input line is provided to the column refresh signal line of the display area through the bending area for column refresh of the data line of the display area.

[0074] The embodiment of the present application also includes a plurality of refresh groups, each refresh group including at least two adjacent column refresh signal lines, and the column refresh signal lines in each refresh group are connected to the same column refresh fan-out line.

[0075] In order to achieve fast refresh, the plurality of column refresh signal lines in the embodiment of the present application are divided into a plurality of refresh groups, each refresh group including at least two adjacent column refresh signal lines, for example, one refresh group including two column refresh signal lines, four column refresh signal lines, eight column refresh signal lines, etc. It should be noted that the plurality of column refresh signal lines belonging to the same refresh group are connected to the same column refresh input line, that is, the refresh control signals in all column refresh signal lines of the same refresh group are also the same signal.

[0076] In order to better connect the column refresh signal line and the column refresh input line, referring to Figure 2 The bending area includes a plurality of column refresh adapter lines.

[0077] The column refresh adapter line is arranged between the column refresh input line and the column refresh signal line.

[0078] The column refresh input line, the column refresh adapter line and the column refresh signal line are one-to-one coupled.

[0079] In the embodiment of the present application, in order to effectively shorten the length of the lower frame, referring to Figure 2 The bending area includes a plurality of column refresh adapter lines, the column refresh adapter line is arranged between the column refresh input line and the column refresh signal line, in order to achieve transmission of the refresh control signal, the column refresh input line, the column refresh adapter line and the column refresh signal line are one-to-one coupled.

[0080] Exemplarily, referring to Figure 2As shown, the column refresh input line 1 of the non-bending area is coupled with the column refresh signal line 1 of the display area through the column refresh transition line 1 of the bending area and the column refresh signal line 2 of the display area is coupled with the column refresh transition line 2 of the bending area, the column refresh input line 3 of the non-bending area is coupled with the column refresh signal line 3 of the display area through the column refresh transition line 3 of the bending area, the column refresh input line 4 of the non-bending area is coupled with the column refresh signal line 4 of the display area through the column refresh transition line 4 of the bending area, the column refresh input line 5 of the non-bending area is coupled with the column refresh signal line 5 of the display area through the column refresh transition line 5 of the bending area, and the column refresh input line 6 of the non-bending area is coupled with the column refresh signal line 6 of the display area through the column refresh transition line 6 of the bending area. It should be noted that the column refresh input line 1 is coupled with the column refresh circuit 1, and the column refresh input line 1 can be electrically connected with a refresh group of the display area, and the refresh group can include at least two column refresh signal lines. The column refresh input line 2 is coupled with the column refresh circuit 2, and the column refresh input line 2 can be electrically connected with a refresh group of the display area, and the refresh group can include at least two column refresh signal lines. The column refresh input line 3 is coupled with the column refresh circuit 3, and the column refresh input line 3 can be electrically connected with a refresh group of the display area, and the refresh group can include at least two column refresh signal lines.

[0081] According to the signal direction of the refresh control signal, the refresh control signal in the column refresh input line is transmitted through the column refresh transition line and then provided to the column refresh signal line of the display area for column refresh of the data line of the display area.

[0082] In an implementable manner, in order to make the length of the lower frame shorter, referring to Figure 3 As shown, the display panel further includes a fan-out area between the display area and the bending area.

[0083] The fan-out area includes column refresh fan-out lines.

[0084] The column refresh fan-out lines are arranged between the column refresh transition lines and the column refresh signal lines.

[0085] The column refresh transition lines, the column refresh fan-out lines and the column refresh signal lines are one-to-one coupled.

[0086] In the embodiments of the present application, the number of column refresh fan-out lines of the fan-out area is the same as the number of column refresh signal lines in the display area. For example, the column refresh fan-out lines are arranged between the column refresh transition lines and the column refresh signal lines. In order to realize the transmission of the refresh control signal, the column refresh transition lines, the column refresh fan-out lines and the column refresh signal lines are one-to-one coupled, that is, the refresh control signal is transmitted through the column refresh input line, then enters the column refresh transition line and the column refresh fan-out line in sequence, and finally is provided to the column refresh signal line of the display area for column refresh of the data line of the display area.

[0087] After introducing the transmission line related to column refresh, the transmission process of data voltage signal in the transmission line related to data line is introduced below.

[0088] Referring to FIG. 1, the display area further includes data lines. Figure 2 Figure 3

[0089] Each refresh group is provided with data lines on both sides.

[0090] In the embodiment of the present application, the display area further includes a plurality of data lines, and the data voltage signal in the data line is updated during the display process, so as to realize the refresh display of different display pictures. In order to facilitate the transmission of signals, each refresh group in the display area is provided with data lines on both sides, as shown in FIG. 1. The refresh control signal in one refresh group is used to provide a data line on one side of the refresh group (for example, the data line on the left side of the refresh group or the data line on the right side of the refresh group), and correspondingly, the refresh control signal in the next refresh group is used to provide a data line on one side of the next refresh group. Figure 2

[0091] At least two data lines are arranged between the above two refresh groups, as shown in FIG. 1, and four data lines are included in one refresh group. Figure 3

[0092] Considering that at least two column refresh signal lines are included in each refresh group, for example, two column refresh signal lines, four column refresh signal lines, eight column refresh signal lines, etc. are included in one refresh group, in the embodiment of the present application, at least two data lines are arranged between the two refresh groups of the display area. When two column refresh signal lines are included in one refresh group, two data lines are arranged between the corresponding two refresh groups; when four column refresh signal lines are included in one refresh group, four data lines are arranged between the corresponding two refresh groups; when eight column refresh signal lines are included in one refresh group, eight data lines are arranged between the corresponding two refresh groups.

[0093] Referring to FIG. 1, the fan-out area further includes data fan-out lines, and the bending area further includes a plurality of data transfer lines. Figure 2

[0094] The data transfer lines, the data fan-out lines and the data lines are one-to-one coupled.

[0095] In the embodiment of the present application, in order to provide the data voltage signal for the data line of the display area, the fan-out area further includes data fan-out lines, and the bending area further includes a plurality of data transfer lines, and the data transfer lines, the data fan-out lines and the data lines are one-to-one coupled.

[0096] ​​​​​For example, the number of data fan-out lines in the fan-out area is the same as the number of data lines in the display area. For example, a data fan-out line is provided between the data adapter cable and the data line. In order to realize the transmission of data voltage signal, the data adapter cable, the data fan-out line and the data line are coupled one-to-one, that is, the data voltage signal enters the data adapter cable and the data fan-out line in sequence, and is finally provided to the data line of the display area for column refresh.

[0097] See Figure 2 As shown, the data adapter cable 1 in the bend area and the data cable 1 in the display area are coupled together. Figure 3 It can be seen that data adapter cable 1 in the bend area is coupled to data line 1 in the display area via data fan-out cable 1 in the fan-out area. Correspondingly, data adapter cable 2 in the bend area is coupled to data line 2 in the display area via data fan-out cable 2 in the fan-out area, data adapter cable 3 in the bend area is coupled to data line 3 in the display area via data fan-out cable 3 in the fan-out area, data adapter cable 4 in the bend area is coupled to data line 4 in the display area via data fan-out cable 4 in the fan-out area, data adapter cable 5 in the bend area is coupled to data line 5 in the display area via data fan-out cable 5 in the fan-out area, and data adapter cable 6 in the bend area is coupled to data line 6 in the display area via data fan-out cable 6 in the fan-out area.

[0098] For easier wiring in bending areas, please refer to... Figure 2 As shown, the data transfer lines and column refresh transfer lines are arranged alternately.

[0099] During implementation, the addition of multiple column refresh adapters led to a corresponding increase in the routing of the bending area. In order not to increase the width of the bending pitch in the bending area, in this embodiment, the bending pitch of the bending area is reduced to a rectangular strip of 13um.

[0100] See Figure 3 As shown, the data fan-out lines and column refresh fan-out lines are curved.

[0101] To shorten the bottom border and facilitate routing, in this embodiment, the data fan-out lines and column refresh fan-out lines are routed with bends. (See also...) Figure 3 As shown, the data fan-out lines and column refresh fan-out lines are usually arranged alternately in the fan-out area. For example, data fan-out line 1, column refresh fan-out line 1, ... data fan-out line X, column refresh fan-out line X, ... data fan-out line n, column refresh fan-out line n.

[0102] In an embodiment, each of the data fan-out lines comprises a first data fan-out sub-line and a second data fan-out sub-line, and a first included angle is formed between the first data fan-out sub-line and the second data fan-out sub-line, and the first included angle is usually an acute angle or a right angle, and the range of the first included angle is not particularly limited herein. For example, refer to FIG. 2A. Figure 3 As shown in FIG. 2A, the data voltage signal can first pass through the first data fan-out sub-line arranged in the horizontal direction, and then pass through the second data fan-out sub-line arranged in the vertical direction. For example, refer to FIG. 2B. Figure 3 As shown in FIG. 2B, the first data fan-out sub-line X1 arranged in the horizontal direction and the second data fan-out sub-line X2 arranged in the vertical direction, and then the data line is provided to the display area.

[0103] In an embodiment, each of the column refresh fan-out lines comprises a first column refresh fan-out sub-line and a second column refresh fan-out sub-line, and a second included angle is formed between the first column refresh fan-out sub-line and the second column refresh fan-out sub-line, and the second included angle is usually an acute angle or a right angle, and the range of the second included angle is not particularly limited herein. For example, refer to FIG. 3A. Figure 3 As shown in FIG. 3A, the refresh control signal can first pass through the first column refresh fan-out sub-line arranged in the horizontal direction, and then pass through the second column refresh fan-out sub-line arranged in the vertical direction. For example, refer to FIG. 3B. Figure 3 As shown in FIG. 3B, the first column refresh fan-out sub-line X1 arranged in the horizontal direction and the second column refresh fan-out sub-line X2 arranged in the vertical direction, and then the column refresh signal line is provided to the display area.
