[0040] Hereinafter, the present disclosure will be described in more detail with reference to the accompanying drawings.

[0041] Figure 1 is a block diagram showing a display device according to an embodiment of the present disclosure. Figure 2 is a diagram explaining Figure 1 the operation of the touch module.

[0042] Referring to Figure 1 and Figure 2 , the display device 10 may include a display module for displaying an image and a touch module for recognizing a user's input action or touch event. The touch module may include a touch driver 300 and a touch sensor 400.

[0043] The display panel driver 100 can drive the display panel 200 to display an image. The display panel driver 100 can receive input image data IMG and an input control signal CONT from an external device (not shown). For example, the input image data IMG can include red image data, green image data, and blue image data. The input image data IMG can include white image data. The input image data IMG can include magenta image data, yellow image data, and cyan image data. The input control signal CONT can include a main clock signal and a data enable signal. The input control signal CONT can further include a vertical synchronization signal and a horizontal synchronization signal.

[0044] The display panel driver 100 can generate a display panel driving signal DPS based on the input image data IMG and the input control signal CONT, and provide the display panel driving signal DPS to the display panel 200. In an embodiment, the display panel driving signal DPS can include a gate signal and a data signal, and the display panel driver 100 can include a gate driver that provides a gate signal to the display panel 200, a data driver that provides a data signal to the display panel 200, and a driving controller that controls the gate driver and the data driver.

[0045] The display panel 200 can include gate lines, data lines, and pixels PX electrically connected to the gate lines and the data lines, respectively.

[0046] The touch driver 300 can drive the touch sensor 400 to sense a touch of the input device 20. The touch driver 300 can generate a touch driving signal TXS and provide the touch driving signal TXS to the touch sensor 400, and receive a touch sensing signal RXS from the touch sensor 400. The touch driver 300 can sense the touch of the input device 20 based on the touch sensing signal RXS. The touch driver 300 can generate touch data TD representing the sensed touch and provide the touch data TD to the display panel driver 100 or an external device.

[0047] The touch sensor 400 can be a capacitive touch sensor that detects a capacitance change caused by a touch of the input device 20. For example, as Figure 2 shown, the input device 20 can be a conductive object such as a user's body or a stylus. The touch sensor 400 can be mounted on one side of the display panel 200 or formed within the display panel 200. For example, the touch sensor 400 can be formed using an OCTA (On Cell Touch AMOLED) method in which the touch sensor 400 is embedded in the display panel 200.

[0048] Figure 3 is a diagram showing Figure 1 the touch module.

[0049] Reference Figures 1 to 3 , the touch sensor 400 may include touch driving lines TX1A to TX1B (as Figure 3 described therein, meaning touch driving lines TX1A to TX3A and TX1B to TX3B) and touch sensing lines RX1 to RX3.

[0050] The touch driving lines TX1A to TX1B included in the touch sensor 400 may extend in a first direction D1, and the touch sensing lines RX1 to RX3 included in the touch sensor 400 may extend in a second direction D2 different from the first direction D1. In an embodiment, the second direction D2 may intersect the first direction D1.

[0051] The touch driving lines TX1A to TX1B may be connected to the touch driver 300 through driving channels (not shown), and the touch sensing lines RX1 to RX3 may be connected to the touch driver 300 through sensing channels (not shown). The touch driver 300 may provide a touch driving signal TXS to the touch driving lines TX1A to TX1B and receive a touch sensing signal RXS from the touch sensing lines RX1 to RX3.

[0052] In an embodiment, as Figure 3As shown, at least two of the touch drive lines TX1A to TX1B can be connected to one drive channel. For example, any one of the touch drive lines TX1A, TX2A, TX3A provided on the first side of the reference line RL and any one of the touch drive lines TX3B, TX2B, TX1B provided on the second side of the reference line RL can be connected to one drive channel, where the second side of the reference line RL is opposite to the first side of the reference line RL. The first side and the second side can correspond to the second direction D2. Therefore, the touch drive lines connected to one drive channel can receive the same touch drive signal TXS. For example, the first touch drive line TX1A on the first side and the first touch drive line TX1B on the second side can be connected to one drive channel and receive the same touch drive signal TXS. For example, the second touch drive line TX2A on the first side and the second touch drive line TX2B on the second side can be connected to one drive channel and receive the same touch drive signal TXS. For example, the third touch drive line TX3A on the first side and the third touch drive line TX3B on the second side can be connected to one drive channel and receive the same touch drive signal TXS. Each of the drive channels connected to different pairs of touch drive lines (for example, connected to a pair of touch drive lines TX1A and TX1B, a pair of touch drive lines TX2A and TX2B, or a pair of touch drive lines TX3A and TX3B) can apply different touch drive signals TXS. Therefore, each pair of touch drive lines TX1A and TX1B, TX2A and TX2B, TX3A and TX3B can receive different touch drive signals TXS.

[0053] Capacitors C11A to C31B (as Figure 3 described, meaning capacitors C11A to C13A, C11B to C13B, C21A to C23A, C21B to C23B, C31A to C33A, and C31B to C33B) can be formed by the touch drive lines TX1A to TX1B and the touch sense lines RX1 to RX3. The positions where the capacitors C11A to C31B are formed can be the positions where the touch drive lines TX1A to TX1B overlap with the touch sense lines RX1 to RX3. For example, the capacitor C11A can be formed on the first side by the first touch drive line TX1A and the first touch sense line RX1. For example, the capacitor C21A can be formed on the first side by the first touch drive line TX1A and the second touch sense line RX2. For example, the capacitor C31A can be formed on the first side by the first touch drive line TX1A and the third touch sense line RX3. In Figures 3 to 5 order to facilitate explanation, the capacitors C11A to C31B are shown at positions different from the positions where they overlap with the touch drive lines TX1A to TX1B and the touch sense lines RX1 to RX3.

[0054] The reference region RR, the first reference region RRA, and the second reference region RRB may be defined by a third touch driving line TX3A on the first side and a third touch driving line TX3B on the second side. The third touch driving line TX3A on the first side and the third touch driving line TX3B on the second side may be the touch driving lines closest to the reference line RL. The reference region RR may be the region between the third touch driving line TX3A on the first side and the third touch driving line TX3B on the second side in the region of the touch sensor 400. The first reference region RRA may be the region on the first side of the reference region RR in the region of the touch sensor 400. The second reference region RRB may be the region on the second side of the reference region RR in the region of the touch sensor 400.

[0055] When the touch sensor 400 is touched by the input device 20, the touch driver 300 may sense changes in the capacitances C11A to C31B, and may sense the touch of the input device 20 based on the changes in the capacitances C11A to C31B.

[0056] Each of the touch sensing lines RX1, RX2, RX3 may include a first sub-sensing line RX1A, RX2A, RX3A provided on the first side and a second sub-sensing line RX1B, RX2B, RX3B provided on the second side.

[0057] Figure 4 It is a diagram for explaining the operation in which the Figure 3 touch sensor is touched by the input device in a point form in the first reference region or the second reference region. Figure 5 It is a diagram for explaining the operation in which the Figure 3 touch sensor is touched by the input device in a line form in the first reference region or the second reference region.

[0058] Refer to Figures 1 to 5 and the touch sensor 400 may be touched by the input device 20 in a point form.

[0059] For example, as shown in Figure 4 , the touch sensor 400 may be touched by the input device 20 in a point form in the first reference region RRA or the second reference region RRB. In this case, the capacitances C11A to C31 may change only at the touch moment. The touch driver 300 may sense the touch of the input device 20 in a point form based on the changes in the capacitances C11A to C31B.

[0060] The touch sensor 400 may be touched by the input device 20 in a line form.

[0061] For example, as shown in Figure 5As shown, the touch sensor 400 can be touched in a line form by the input device 20 in the first reference area RRA or the second reference area RRB. The magnitudes of the capacitances C11A to C31B can vary according to the position. The touch driving lines TX1A, TX2A, TX3A provided in the first reference area RRA can be connected to different driving channels, and the touch driving lines TX3B, TX2B, TX1B provided in the second reference area RRB can be connected to different driving channels. Accordingly, the magnitudes of the capacitances C11A to C33A formed in the first reference area RRA can be different from each other, and the magnitudes of the capacitances C11B to C33B formed in the second reference area RRB can be different from each other. For example, the magnitudes of the capacitances C13A and C12A can be different, and the magnitudes of the capacitances C12A and C11A can be different. Accordingly, the capacitances C12A, C13A with different magnitudes adjacent to the touch position of the input device 20 can change over a certain period of time, and the amount of change in each of the capacitances C12A, C13A can change according to the movement of the input device 20. Correspondingly, the touch driver 300 can sense the touch of the input device 20 in a line form.

[0062] Figure 6 is a diagram explaining Figure 3 the operation in which the touch sensor is touched in a point form by the input device in the reference area. Figure 7 is a diagram explaining Figure 3 the operation in which the touch sensor is touched in a line form by the input device in the reference area.

[0063] Refer to Figure 6 and Figure 7 In, the touch sensor 400 can be touched in a point form or a line form by the input device 20 in the reference area RR.

[0064] Since the touch driving lines TX3A, TX3B provided in the reference area RR are connected to one driving channel, the capacitances C13A, C13B formed by the touch driving lines TX3A, TX3B provided in the reference area RR and the first touch sensing line RX1 can be equal to each other. Similarly, the magnitudes of the capacitances C23A and C23B can be the same as each other, and the magnitudes of the capacitances C33A and C33B can be the same as each other.

[0065] Accordingly, when the touch sensor 400 is touched in a point form by the input device 20 in the reference area RR, the capacitances C13A, C13B with the same magnitude adjacent to the touch position of the input device 20 may change incorrectly at the touch moment. The touch driver 300 may not accurately sense the touch of the input device 20 in a point form.

[0066] In addition, when the touch sensor 400 is touched by the input device 20 in the form of a line in the reference area RR (especially in the second direction D2), the capacitances C13A and C13B of the same size adjacent to the touch position of the input device 20 can change over a certain period of time, and although the input device 20 moves, the change amounts of each of the capacitances C13A and C13B can be the same. The touch driver 300 may not accurately sense the touch of the input device 20 in the form of a line.

[0067] Thus, when at least two of the touch driving lines TX1A to TX1B are connected to one driving channel and the touch sensor 400 is touched by the input device 20 in the form of a point or a line in the reference area RR, the touch driver 300 may not accurately sense the touch of the input device 20.

[0068] For the touch driving lines TX1A to TX1B of the touch sensor 400 according to an embodiment of the present disclosure, in the reference area RR, the capacitances C13A, C23A, and C33A on the first side are different from the capacitances C13B, C23B, and C33B on the second side. Therefore, the touch driver 300 can accurately sense the touch of the input device 20 in the form of a point or a line in the reference area RR. This will be described in detail later in Figure 8 and Figure 9 in.

[0069] Figure 8 and Figure 9 are diagrams showing the touch driving lines and touch sensing lines of a touch sensor according to an embodiment of the present disclosure.

[0070] Referring to Figures 1 to 9 , each of the touch sensing lines RX1, RX2, and RX3 may include first sub-sensing lines RX1A, RX2A, and RX3A provided on the first side of the reference line RL and second sub-sensing lines RX1B, RX2B, and RX3B provided on the second side of the reference line RL, and the first sub-sensing lines RX1A, RX2A, and RX3A may be different from the second sub-sensing lines RX1B, RX2B, and RX3B. In an embodiment, the first sub-sensing lines RX1A, RX2A, and RX3A may have a different structure from the second sub-sensing lines RX1B, RX2B, and RX3B. For example, the first sub-sensing lines RX1A, RX2A, and RX3A may include a first line L1 and a second line L2 at least partially surrounded by the first line L1, and the second sub-sensing lines RX1B, RX2B, and RX3B may include the first line L1. That is, compared with the second sub-sensing lines RX1B, RX2B, and RX3B, the first sub-sensing lines RX1A, RX2A, and RX3A may further include the second line L2.

[0071] Since the first sub-sensing lines RX1A, RX2A, RX3A include the first line L1 and the second line L2, and the second sub-sensing lines RX1B, RX2B, RX3B only include the first line L1, the magnitudes of the capacitances C11A to C33A formed by the first sub-sensing lines RX1A, RX2A, RX3A and the touch driving lines TX1A, TX2A, TX3A are different from the magnitudes of the capacitances C11B to C33B formed by the second sub-sensing lines RX1B, RX2B, RX3B and the touch driving lines TX3B, TX2B, and TX1B. In particular, in the reference region RR, the capacitances C13A, C23A, C33A on the first side may be different from the capacitances C13B, C23B, C33B on the second side. For example, as Figure 8 shown, in the reference region RR, the magnitude of the capacitance C13A formed by the first sub-sensing line RX1A of the first touch sensing line RX1 and the third touch driving line TX3A on the first side may be different from the magnitude of the capacitance C13B formed by the second sub-sensing line RX1B of the first touch sensing line RX1 and the third touch driving line TX3B on the second side.

[0072] Therefore, even when the touch sensor 400 is touched by the input device 20 in the reference region RR, the capacitances C13A, C23A, C33A formed by the first sub-sensing lines RX1A, RX2A, RX3A and the third touch driving line TX3A on the first side and the capacitances C13B, C23B, C33B formed by the second sub-sensing lines RX1B, RX2B, RX3B and the third touch driving line TX3B on the second side can change precisely. Accordingly, the touch driver 300 can precisely sense the touch of the input device 20 in the form of a point in the reference region RR.

[0073] Since the magnitude of the capacitance C13A formed by the first sub-sensing line RX1A of the first touch sensing line RX1 and the third touch driving line TX3A on the first side may be different from the magnitude of the capacitance C13B formed by the second sub-sensing line RX1B of the first touch sensing line RX1 and the third touch driving line TX3B on the second side, the change in the capacitance C13A formed by the first sub-sensing line RX1A of the first touch sensing line RX1 and the third touch driving line TX3A on the first side may be different from the change in the capacitance C13B formed by the second sub-sensing line RX1B of the first touch sensing line RX1 and the third touch driving line TX3B on the second side. Accordingly, the touch driver 300 can precisely sense the touch of the input device 20 in the form of a line in the reference region RR.

[0074] Thus, even if at least two of the touch driving lines TX1A to TX1B are connected to one driving channel and the touch sensor 400 is touched by the input device 20 in the form of a point or a line in the reference area RR, the first sub-sensing lines RX1A, RX2A, RX3A can be different from the second sub-sensing lines RX1B, RX2B, RX3B, so that the touch driver 300 can accurately sense the touch of the input device 20 in the form of a point or a line in the reference area RR.
