Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2020-0174107 filed in Korea on December 14, 2020, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a touch display device, and more particularly, to a touch display device with a narrow frame. Background Art

[0004] As the information age progresses, display devices are rapidly developing. Liquid crystal display (LCD) devices and organic light emitting diode (OLED) display devices have been developed and widely used as flat panel displays (FPDs) with a thin profile, light weight, and low power consumption.

[0005] Recently, a touch display device in which a touch panel is provided on a display panel is widely used.

[0006] A touch display device called a touch screen is used as an output device for displaying an image and an input device for receiving a user command by touching a portion of the image. When a user views an image of the display panel and touches the touch panel, the touch panel detects position information of the touched portion and recognizes the user command by comparing the detected position information with the position information of the image.

[0007] A touch panel of a touch display device may be classified into a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type according to a method of detecting position information.

[0008] Capacitive touch panels are widely used due to their excellent durability, long life, easy support for multi-point touch, and high light transmittance.

[0009] Capacitive touch panels can be classified into mutual capacitance type and self-capacitance type. In the mutual capacitance type touch panel, the transmission line and the receiving line are independently formed and the change of the capacitance between the transmission line and the receiving line due to the touch is detected, and in the self-capacitance type touch panel, a voltage is applied to an independent touch electrode in a certain area and the change of the capacitance of the touch electrode due to the touch is detected.

[0010] In a touch panel, since the driving electrodes and the sensing electrodes are formed on the same layer as each other, the touch area requires a wiring area for connecting the wiring of the sensing electrodes or the driving electrodes. The touch area is reduced due to the wiring area and the touch accuracy is deteriorated.

[0011] Therefore, the wiring area is set in the non-display area of ​​the touch panel. However, since the wiring area of ​​the non-display area serves as a frame of the touch panel, a touch panel with a narrow frame needs to be studied. Summary of the invention

[0012] Accordingly, the present disclosure is directed to a touch display device that substantially obviates one or more problems due to limitations and disadvantages of the related art.

[0013] An object of the present disclosure is to provide a touch display device having a narrow frame by eliminating a wiring area in a touch panel.

[0014] Additional features and advantages of the present disclosure will be set forth in the following description, and will in part become apparent from the description, or may be learned through practice of the present disclosure. These and other advantages of the present disclosure will be realized and obtained through the structures specifically pointed out in the written description and claims and the accompanying drawings.

[0015] To achieve these and other advantages, in accordance with the purposes of the present disclosure, as specifically presented and generally described herein, a touch display device includes a touch sensor and has a touch area and a non-display area located on one side of the touch area and containing a touch drive unit, the touch display device including: a plurality of drive electrodes within the touch area, the plurality of drive electrodes being connected to each other by at least one bridge line to form a plurality of row touch drive lines; a plurality of sensing electrodes, the plurality of sensing electrodes intersecting the plurality of drive electrodes within the touch area; and at least one drive wiring extending from at least one bridge line connecting the plurality of drive electrodes, wherein the at least one drive wiring extends from the touch area to the non-display area.

[0031] Figure 1 is a perspective view showing a touch display device according to a first embodiment of the present disclosure.

[0032] exist Figure 1 , the touch display device 100 including the touch sensor TS senses a touch and a touched position by detecting a change in mutual capacitance due to a user's touch through the plurality of touch electrodes 201 to 236 and 310 to 360 during a touch period.

[0033] The touch display device 100 including the touch sensor TS displays an image through a plurality of pixels P each having a light emitting diode 120 during a display period.

[0034] Each of the plurality of pixels includes red, green, and blue sub-pixels SP or red, green, blue, and white sub-pixels SP.

[0035] The touch display device 100 includes a plurality of sub-pixels SP in a matrix form on a substrate 111 , an encapsulation layer 130 over the plurality of sub-pixels SP, and a touch sensor TS over the encapsulation layer 130 .

[0036] The substrate 111 of the touch display device 100 includes a display area AA, and a plurality of sub-pixels SP are disposed in the display area AA to display an image. Each of the plurality of sub-pixels SP includes a pixel driving circuit and a light emitting diode 120 connected to the pixel driving circuit.

[0037] The pixel driving circuit may include a switching thin film transistor (TFT) T1, a driving TFT T2 and a storage capacitor Cst. When a scan signal is supplied to the scan line SL, the switching TFT T1 is turned on to transmit a data signal supplied to the data line DL to the storage capacitor Cst and the gate of the driving TFT T2.

[0038] The driving TFT T2 adjusts a current supplied from a high-level voltage (VDD) line to the light emitting diode 120 in response to a data signal supplied to a gate electrode of the driving TFT T2 to control the amount of light emitted by the light emitting diode 120 .

[0039] Even after the switching TFT T1 is turned off, the driving TFT T2 supplies a constant current due to the voltage charged in the storage capacitor Cst before the data signal of the next frame is supplied to keep the light emitting diode 120 emitting light.

[0044] The cathode faces the anode, and the light emitting layer is interposed between the anode and the cathode.

[0045] When voltage is applied to the anode and cathode of the light emitting diode 120, holes injected from the anode and electrons injected from the cathode are transferred to the light emitting layer to form excitons. When the excitons transition from an excited state to a ground state, light is emitted from the light emitting layer to the outside.

[0046] The encapsulation layer 130 prevents external moisture or oxygen from penetrating into the light emitting diode 120. The encapsulation layer 130 may include a plurality of inorganic layers and a plurality of organic layers therebetween, and may provide the inorganic layer as an uppermost layer.

[0047] The touch sensor TS is disposed on the encapsulation layer 130. The touch display device 100 does not include an additional wiring region where wiring for applying a signal to the touch sensor TS is disposed.

[0048] In the touch display device 100, since a plurality of wirings for transmitting signals between the plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360 are not provided in the non-display area NA ( Figure 2 ) but is set in the touch area TA ( Figure 2 ), so the wiring area including wiring located on one side of the touch sensor TS is omitted.

[0049] Therefore, a touch sensor TS having a narrow frame is provided.

[0050] Figure 2 is a plan view showing a touch sensor of a touch display device according to a first embodiment of the present disclosure, Figure 3 It shows Figure 2 A magnified view of a portion of .

[0051] exist Figure 2 and Figure 3 In the embodiment, the touch sensor TS includes a touch area TA and a non-display area NA. A plurality of driving electrodes 201 to 236 and a plurality of sensing electrodes 310 to 360 are disposed in the touch area TA, and a pad portion is disposed in the non-display area NA.

[0052] The plurality of driving electrodes 201 to 236 include a plurality of unit electrodes connected along the X-axis (horizontal direction) to form a first row of touch driving lines TL1, a second row of touch driving lines TL2, a third row of touch driving lines TL3, a fourth row of touch driving lines TL4, a fifth row of touch driving lines TL5 and a sixth row of touch driving lines TL6.

[0053] For example, the plurality of driving electrodes 201 to 236 having a comb-shaped pattern may be symmetrically connected, and the plurality of driving electrodes 201 to 236 may be connected to each other through the plurality of bridge wires TW1 a to TW6 d to constitute a plurality of electrode rows.

[0054] The plurality of sensing electrodes 310 to 360 , each having a single electrode, has a bar shape extending along the Y-axis (vertical direction).

[0055] The plurality of sensing electrodes 310 to 360 may have a comb pattern alternately disposed with the comb pattern of the plurality of driving electrodes 201 to 236 , such that the plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360 have a comb shape.

[0056] Alternatively, the plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360 having a comb shape may be in a mesh shape having a plurality of openings. The plurality of openings may correspond to the plurality of sub-pixels SP ( Figure 1 )A luminous area that emits light.

[0057] The shapes of the plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360 are not limited to the first embodiment. The plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360 may have various shapes.

[0058] For example, the first to thirty-sixth driving electrodes 201 to 236 and the first to sixth sensing electrodes 310 to 360 are arranged in the touch area TA.

[0061] The twenty-fifth to thirtieth driving electrodes 225 to 230 are connected to each other through fifth bridge lines TW5a to TW5d to form a fifth row of touch driving lines TL5, and the thirty-first to thirty-sixth driving electrodes 231 to 236 are connected to each other through sixth bridge lines TW6a to TW6d to form a sixth row of touch driving lines TL6.

The first to sixth bridge lines TW1a to TW6d may be electrically connected to the first to sixth auxiliary bridge lines TW1a-B to TW6d-B, respectively.

[0063] Since the first to sixth auxiliary bridge lines TW1 a -B to TW6 d -B reduce the resistance of the first to sixth bridge lines TW1 a to TW6 d , the touch sensitivity of the first to sixth bridge lines TW1 a to TW6 d is improved.

[0064] The first sensing electrodes 310 to the sixth sensing electrodes 360 are arranged to intersect the first row of touch drive lines TL1 to the sixth row of touch drive lines TL6. The first sensing electrodes 310 are arranged to intersect the first drive electrode 201, the seventh drive electrode 207, the thirteenth drive electrode 213, the nineteenth drive electrode 219, the twenty-fifth drive electrode 225, and the thirty-first drive electrode 231, and the second sensing electrodes 320 are arranged to intersect the second drive electrode 202, the eighth drive electrode 208, the fourteenth drive electrode 214, the twentieth drive electrode 220, the twenty-sixth drive electrode 226, and the thirty-second drive electrode 232.

[0067] Although for convenience, the plurality of driving electrodes 201 to 236 are illustrated as being divided into blocks of the first driving electrode to the thirty-sixth driving electrode, the first driving electrode 201 is defined as a first-first driving electrode 201a and a first-second driving electrode 201b that are symmetrical to each other, and the first-first driving electrode 201a and the first-second driving electrode 201b are connected to each other via a first-first jumping line JW1a.

[0070] The second driving electrode 202 to the sixth driving electrode 206, the eighth driving electrode 208 to the twelfth driving electrode 212, the fourteenth driving electrode 214 to the eighteenth driving electrode 218, the twentieth driving electrode 220 to the twenty-fourth driving electrode 224, the twenty-sixth driving electrode 226 to the thirtieth driving electrode 230, and the thirty-second driving electrode 232 to the thirty-sixth driving electrode 236 are defined as two driving electrodes symmetrical to each other, and the two driving electrodes are connected to each other through one of the first to sixth jumper wires JW1b to JW1f, JW2b to JW2f, JW3b to JW3f, JW4b to JW4f, JW5b to JW5f, and JW6b to JW6f.

[0071] Therefore, the second to sixth sensing electrodes 320 to 360 are arranged between the second to sixth driving electrodes 202 to 206, the eighth to twelfth driving electrodes 208 to 212, the fourteenth to eighteenth driving electrodes 214 to 218, the twentieth to twenty-fourth driving electrodes 220 to 224, the twenty-sixth to thirtieth driving electrodes 226 to 230, and the thirty-second to thirty-sixth driving electrodes 232 to 236.

[0072] The first-first driving electrodes 201a and the first-second driving electrodes 201b are symmetrically arranged to include comb patterns protruding toward each other. The first sensing electrode 310 includes a comb pattern alternately arranged with the comb pattern of the first-first driving electrodes 201a and a comb pattern alternately arranged with the comb pattern of the first-second driving electrodes 201b.

[0075] Wirings LD1 to LD12 and LS1 to LS6 are disposed in the pad portion of the non-display area NA. The first to sixth drive wirings LD1 to LD6 extend to be connected to the first to sixth bridge lines TW1a to TW6d, respectively, and the first to sixth sense wirings LS1 to LS6 are connected to the first to sixth sense electrodes 310 to 360, respectively.

[0076] The touch driving part PAD is connected to the plurality of row touch driving lines TL1 to TL6 through the plurality of driving wirings LD1 to LD6 to transmit a touch driving signal, and receives a touch sensing signal from the plurality of sensing electrodes 310 to 360 through the plurality of sensing wirings LS1 to LS6.

[0077] Hereinafter, the operation of the touch driving unit PAD will be described in detail. The touch driving unit PAD sequentially applies a touch driving signal to the plurality of driving electrodes 201 to 236 of the touch sensor TS. By sequentially applying the touch driving signal for sensing touch to the plurality of driving electrodes 201 to 236 of the touch sensor TS, capacitance is generated between the plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360.

[0078] The touch driving part PAD receives a touch sensing signal through the plurality of sensing electrodes 310 to 360 according to the touch driving signal applied sequentially to determine the touch input position of the user. The touch sensing signal includes a change in capacitance between the plurality of driving electrodes 201 to 236 and the plurality of sensing electrodes 310 to 360, which is generated by the touch driving signal sequentially applied to the plurality of driving electrodes 201 to 236 of the touch sensor TS according to the touch of the finger.

[0079] The touch driving unit PAD sequentially receives the change in capacitance between the first driving electrode 201 and the plurality of sensing electrodes 310 to 360 through the plurality of sensing electrodes 310 to 360 according to the touch driving signal applied to the first driving electrode 201.

Similarly, the touch driving unit PAD sequentially receives the change in capacitance according to the touch driving signal applied to the other driving electrodes. The touch driving unit PAD sequentially receives the change in capacitance between the last driving electrode 236 and the plurality of sensing electrodes 310 to 360 through the plurality of sensing electrodes 310 to 360 according to the touch driving signal applied to the last driving electrode 236.

[0080] In the touch display device 100 ( Figure 1 ), the first drive wiring LD1 extends from the first-first bridge wire TW1a and the first-second bridge wire TW1b connecting the first drive electrode 201 to the third drive electrode 203, and the second drive wiring LD2 extends from the first-third bridge wire TW1c and the first-fourth bridge wire TW1d connecting the fourth drive electrode 204 to the sixth drive electrode 206.

[0138] Although not shown, the second drive wiring LD2, the fourth drive wiring LD4, the sixth drive wiring LD6, and the seventh drive wiring LD7 to the twelfth drive wiring LD12 may be arranged in a similar manner in the touch area TA ( Figure 2 ) without electrical interference.

[0139] Although the touch display device 100 ( Figure 1 ), the touch sensor TS( Figure 2 ) includes a plurality of driving electrodes 201 to 236 ( Figure 2 ) and a plurality of sensing electrodes 310 to 360 ( Figure 2 ), the number of multiple drive electrodes and multiple sense electrodes may vary within the scope of the present disclosure.

[0140] Therefore, multiple jumpers JW1a to JW6f ( Figure 2 ) and the number and position of the plurality of bridge wires TW1a to TW6d ( Figure 2 ) can be changed according to the design, and the plurality of drive wirings LD1 to LD12 ( Figure 2 ) and the number and position of the plurality of sensing wirings LS1 to LS6 ( Figure 2 ) can vary according to design.

Therefore, when testing the touch sensor TS ( Figure 2 ), the degradation of the pattern can be easily detected.

[0142] A plurality of driving electrodes 201 to 236 ( Figure 2 ) and a plurality of sensing electrodes 310 to 360 ( Figure 2 ) can be divided into a first pattern P1, a second pattern P2, a third pattern P and a fourth pattern P4. The first driving electrode 201, the second driving electrode 202, the third driving electrode 203, the seventh driving electrode 207, the eighth driving electrode 208, the ninth driving electrode 209, the thirteenth driving electrode 213, the fourteenth driving electrode 214, and the fifteenth driving electrode 215 connected to each other through the first-first bridge wire TW1a to the third-first bridge wire TW3a connected to the first driving wiring LD1, the third driving wiring LD3, and the fifth driving wiring LD5 may be defined as a first pattern P1, and the fourth driving electrode 204, the fifth driving electrode 205, the sixth driving electrode 206, the tenth driving electrode 210, the eleventh driving electrode 211, the twelfth driving electrode 212, the sixteenth driving electrode 216, the seventeenth driving electrode 217, and the eighteenth driving electrode 218 connected to each other through the first-third bridge wire TW1c to the third-third bridge wire TW3c connected to the second driving wiring LD2, the fourth driving wiring LD4, and the sixth driving wiring LD6 may be defined as a second pattern P2.

[0144] Since the first pattern P1 and the second pattern P2 are arranged symmetrically to each other, and the third pattern P3 and the fourth pattern P4 are arranged symmetrically to each other, in the touch sensor TS ( Figure 2 )’s testing process can easily detect pattern degradation.

[0145] Therefore, in the touch display device including the touch sensor according to the present disclosure, the plurality of driving electrodes are divided into the first row of touch driving lines to the sixth row of touch driving lines by the first bridge wire to the sixth bridge wire, and at least one driving wiring extends from each of the first row of touch driving lines to the sixth row of touch driving lines. Therefore, the number of the plurality of driving wirings is reduced, and the plurality of driving wirings are arranged between the plurality of driving electrodes within the touch area.

[0146] Furthermore, since a plurality of driving wires are disposed to overlap a plurality of driving electrodes, touch accuracy is improved. Specifically, since regions for a plurality of wires on both sides of the touch area are omitted, a touch sensor having narrow frames on both sides of the touch area TA is provided.

[0147] It is obvious to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure is intended to cover modifications and variations of the present disclosure as long as they are within the scope of the appended claims and their equivalents.
