[0048] In this specification, when it is mentioned that a certain component (or region, layer, part, etc.) is "above", "connected" or "combined" with another component, it means that it can be directly arranged on or directly connected / combined with another component, or a third component can be arranged between them.

[0049] The same reference numerals refer to the same constituent elements. Furthermore, in the drawings, the thickness, proportions, and dimensions of the constituent elements are exaggerated for the purpose of effective illustration of the technical content. "And / or" includes all but one combination of the relevant constituent elements that can be defined.

[0050] The terms "first," "second," etc., can be used to describe multiple constituent elements, but the constituent elements should not be limited by the terms. The terms are used only to distinguish one constituent element from another. For example, without departing from the scope of the invention, a first constituent element can be named a second constituent element, and similarly, a second constituent element can be named a first constituent element. Singular expressions include plural expressions unless the context explicitly indicates a different meaning.

[0051] Furthermore, terms such as "below," "lower side," "above," and "upper side" are used to describe the relationships between the constituent elements shown in the accompanying drawings. These terms are relative concepts and are explained based on the directions indicated in the accompanying drawings.

[0052] Terms such as “including” or “having” should be understood as: used to specify the presence of features, figures, steps, operations, constituent elements, components or combinations thereof described in the specification, rather than precluding the presence or possibility of one or more other features or figures, steps, operations, constituent elements, components or combinations thereof.

[0053] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, terms identical to those defined in commonly used dictionaries shall be interpreted as having the same meaning as in the context of the relevant art, and are hereby expressly defined unless interpreted as having an ideal or overly formal meaning.

[0054] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0055] Figure 1a This is a perspective view of a display device DD according to an embodiment of the present invention. Figure 1b This is an exploded perspective view of a display device DD according to an embodiment of the present invention.

[0056] The display device DD can be a device that is activated by an electrical signal. The display device DD can include a variety of embodiments. Figure 1a An exemplary illustration shows a display device DD used in a smartphone. However, it is not limited to this; the display device DD can be a large electronic device such as a television or monitor, or a small to medium-sized electronic device such as a mobile phone, tablet computer, car navigation system, game console, or smartwatch.

[0057] The display device DD can display an image IM on a display surface IS parallel to each of the first direction DR1 and the second direction DR2, facing a third direction DR3. The display surface IS of the image IM can correspond to the front surface of the display device DD, and can also correspond to the front surface FS of the window 100. Hereinafter, the display surface, front surface of the display device DD, and front surface of the window 100 will use the same reference numerals. The image IM can obviously include both moving images and still images. Figure 1a The image shown in the image IM example depicts a clock and several icons.

[0058] In this embodiment, the front (or upper) and rear (or lower) surfaces of each component are defined based on the direction of the displayed image IM. The front and rear surfaces may be opposite each other in a third direction DR3, and the normal direction of each of the front and rear surfaces may be parallel to the third direction DR3. The distance between the front and rear surfaces in the third direction DR3 may correspond to the thickness of the display panel 210 in the third direction DR3. Furthermore, the directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 are relative concepts and may be changed to other directions. Hereinafter, the first direction to the third direction refers to the directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3, respectively, with reference to the same reference numerals.

[0059] For example, a display device DD according to an embodiment of the present invention can sense user input TC applied from the outside. User input TC includes various forms of input such as a part of the user's body, light, heat, or pressure. In this embodiment, the user input TC is illustrated as a user's hand applied to the front surface. However, this is an exemplary illustration, and as described above, user input TC can be provided in various forms. Furthermore, the display device DD can also sense user input TC applied to the side or rear surface of the display device DD depending on its structure, and is not limited to any particular embodiment.

[0060] A display device DD according to one embodiment may include a window 100, a display module 200, and a housing 300. In this embodiment, the window 100 and the housing 300 are combined to form the appearance of the display device DD.

[0061] Window 100 may include an insulating panel. For example, window 100 may be constructed using glass, plastic, or a combination thereof.

[0062] As described above, the front surface FS of window 100 defines the front surface of display device DD. The transmissive region TA can be an optically transparent region. For example, the transmissive region TA can be a region with a visible light transmittance of approximately 90% or more.

[0063] The border region BZA can be a region with relatively lower light transmittance compared to the transmission region TA. The border region BZA defines the shape of the transmission region TA. The border region BZA can be adjacent to and surround the transmission region TA.

[0064] The border area BZA can have a predetermined color. The border area BZA can cover the surrounding area NAA of the display module 200, thereby preventing the surrounding area NAA from being recognized from the outside. Alternatively, this is an exemplary illustrated scenario; in a window 100 according to an embodiment of the present invention, the border area BZA can also be omitted.

[0065] The display module 200 can display an image IM and sense an input TC. The image IM can be displayed on the front surface IS of the display module 200. The front surface IS of the display module 200 includes an active area AA and a surrounding area NAA. The active area AA can be an area that is activated according to an electrical signal.

[0066] In this embodiment, the active region AA can be the area for displaying the image IM and simultaneously the area for sensing the input TC. The transmission region TA overlaps at least with the active region AA. For example, the transmission region TA overlaps the entire surface or at least a portion of the active region AA. Therefore, the user can identify the image IM or provide the input TC through the transmission region TA. However, this is an exemplary illustrated scenario, and the area within the active region AA for displaying the image IM and the area for sensing the input TC can also be separated from each other, and is not limited to any particular embodiment.

[0067] The surrounding area NAA can be the area covered by the border area BZA. The surrounding area NAA is arranged adjacent to the active area AA. In one embodiment, the surrounding area NAA can surround the active area AA. Drive circuitry or drive wiring for driving the active area AA can be arranged in the surrounding area NAA.

[0068] One embodiment of the display module 200 may include a display panel 210, an input sensing unit 220, a display driving circuit DIC, and a sensing circuit board FTC.

[0069] The display panel 210 may be a configuration that substantially generates an image IM. The image IM generated by the display panel 210 is displayed on the display surface IS through the transmission area TA, thereby being recognized by the user from the outside.

[0070] The input sensing unit 220 senses the input TC applied from the outside. As described above, the input sensing unit 220 can sense the input TC provided to the window 100.

[0071] The display driver circuit DIC is disposed on the display panel 210. The display driver circuit DIC can be mounted on the display panel 210. The display driver circuit DIC is electrically connected to the display panel 210 and provides electrical signals to the display panel 210 for driving the display panel 210.

[0072] The sensing circuit board (FTC) is electrically connected to the input sensing unit 220. In this embodiment, the sensing circuit board (FTC) may include a flexible circuit board (CF) and a sensing drive circuit (TIC). The flexible circuit board (CF) includes sensing lines (not shown). The sensing lines are electrically connected to the input sensing unit 220 and the sensing drive circuit (TIC). The sensing drive circuit (TIC) may be mounted on the flexible circuit board (CF) in a chip-on-film configuration. The input sensing unit 220 can independently receive electrical signals from the display panel 210 via the sensing circuit board (FTC).

[0073] The housing 300, together with the window 100, defines the appearance of the display device DD. The housing 300 provides a predetermined internal space. The display module 200 can be housed within the internal space.

[0074] The housing 300 may include a material with relatively high rigidity. For example, the housing 300 may include glass, plastic, or metal, or include multiple frames and / or plates constructed using combinations thereof. The housing 300 can stably protect the structure of the display device DD housed within the internal space from external impacts.

[0075] Figure 2a This is a plan view of a display panel 210 according to an embodiment of the present invention. Figure 2b This is an equivalent circuit diagram of pixel PX according to an embodiment of the present invention. Figure 2c This is a plan view of an input sensing unit 220 according to an embodiment of the present invention. Figures 2a to 2c For ease of explanation, some structural elements have been omitted from the illustrations.

[0076] Reference Figure 2a In one embodiment, the display panel 210 may include a base substrate BS, multiple pixels PX, multiple signal lines GL, DL, PL, EL, and a display driving circuit DIC. The display driving circuit DIC may include a gate driving circuit IC1 and a data driving circuit IC2.

[0077] The base substrate BS of the display panel 210 can be defined with an active area AA and a surrounding area NAA. The active area AA can be the area where the image is displayed, and the surrounding area NAA can be the area where driving circuits or driving wiring are arranged.

[0078] The base substrate BS may include an insulating substrate. For example, the base substrate BS may be constructed using a glass substrate, a plastic substrate, or a combination thereof.

[0079] Signal lines GL, DL, PL, and EL are connected to pixel PX to transmit electrical signals to pixel PX. An exemplary illustration shows the gate line GL, data line DL, light emission control line EL, and power line PL among the signal lines included in the display panel 210. However, this is an exemplary illustration; signal lines GL, DL, PL, and EL may also include initialization voltage lines and are not limited to any particular embodiment.

[0080] Reference Figure 2b The signal circuit diagram of one pixel PX among a plurality of pixels is illustrated in an enlarged and exemplary manner. Figure 2b The illustration shows a pixel PX connected to the i-th gate line GLi and the i-th light emission control line ELi.

[0081] Multiple gate lines GL are provided and connected to the gate drive circuit IC1 respectively. The gate drive circuit IC1 sequentially provides gate signals corresponding to the gate lines. Pixel PX can receive the gate signals to turn on / off.

[0082] Data lines DL and GL are insulated and cross each other. Multiple data lines DL are provided and connected separately to the data driver circuit IC2. The data driver circuit IC2 provides the data signals corresponding to the data lines. Pixel PX displays the light corresponding to the data signals in the active area AA.

[0083] A pixel (PX) may include a light-emitting element (EE) and a pixel circuit (CC).

[0084] The pixel circuit CC may include multiple transistors TR1 to TR7 and a capacitor CP. The multiple transistors TR1 to TR7 may be formed by low temperature polycrystalline silicon (LTPS) process or low temperature polycrystalline silicon oxide (LTPO) process.

[0085] The pixel circuit CC controls the amount of current flowing through the light-emitting element EE in response to a data signal. The light-emitting element EE can emit light at a predetermined brightness in response to the amount of current supplied from the pixel circuit CC. For this purpose, the level of the first power supply ELVDD can be set higher than the level of the second power supply ELVSS. The light-emitting element EE can include an organic light-emitting element or a quantum dot light-emitting element.

[0086] Each of the plurality of transistors TR1 to TR7 may include an input electrode (or source electrode), an output electrode (or drain electrode), and a control electrode (or gate electrode). In this specification, for convenience, either the input electrode or the output electrode may be referred to as the first electrode, and the other may be referred to as the second electrode.

[0087] The first electrode of the first transistor TR1 is connected to the first power supply ELVDD via the fifth transistor TR5, and the second electrode of the first transistor TR1 is connected to the anode electrode of the light-emitting element EE via the sixth transistor TR6. In this specification, the first transistor TR1 may be referred to as the driving transistor.

[0088] The first transistor TR1 controls the amount of current flowing in the light-emitting element EE according to the voltage applied to the control electrode of the first transistor TR1.

[0089] The second transistor TR2 is connected between the data line DL and the first electrode of the first transistor TR1. Furthermore, the control electrode of the second transistor TR2 is connected to the i-th gate line GLi. When the i-th scan signal is provided to the i-th gate line GLi, the second transistor TR2 is turned on, thereby electrically connecting the data line DL to the first electrode of the first transistor TR1.

[0090] The third transistor TR3 is connected between the second electrode of the first transistor TR1 and the control electrode of the first transistor TR1. The control electrode of the third transistor TR3 is connected to the i-th gate line GLi. When the i-th scan signal is provided to the i-th gate line GLi, the third transistor TR3 is turned on, thereby electrically connecting the second electrode of the first transistor TR1 to the control electrode of the first transistor TR1. Therefore, when the third transistor TR3 is turned on, the first transistor TR1 is connected in a diode configuration.

[0091] The fourth transistor TR4 is connected between node ND and the initialization power generation unit (not shown). Furthermore, the control electrode of the fourth transistor TR4 is connected to the (i-1)th gate line GLi-1. When the (i-1)th scan signal is provided to the (i-1)th gate line GLi-1, the fourth transistor TR4 is turned on, thereby providing the initialization voltage Vint to node ND.

[0092] The fifth transistor TR5 is connected between the power supply line PL and the first electrode of the first transistor TR1. The control electrode of the fifth transistor TR5 is connected to the i-th light-emitting control line ELi.

[0093] The sixth transistor TR6 is connected between the second electrode of the first transistor TR1 and the anode electrode of the light-emitting element EE. Furthermore, the control electrode of the sixth transistor TR6 is connected to the i-th light-emitting control line ELi.

[0094] The seventh transistor TR7 is connected between the initialization power generation unit (not shown) and the anode electrode of the light-emitting element EE. Furthermore, the control electrode of the seventh transistor TR7 is connected to the (i+1)th gate line GLi+1. When the (i+1)th scan signal is provided to the (i+1)th gate line GLi+1, the seventh transistor TR7 is turned on, thereby providing the initialization voltage Vint to the anode electrode of the light-emitting element EE.

[0095] The seventh transistor TR7 can improve the black level performance of pixel PX. Specifically, when the seventh transistor TR7 is turned on, the parasitic capacitor (not shown) of the light-emitting element EE discharges. Therefore, when achieving black brightness, the light-emitting element EE does not emit light due to the leakage current from the first transistor TR1, thus improving the black level performance.

[0096] In addition, although Figure 2b The illustration shows the seventh transistor TR7 with its control electrode connected to the (i+1)th gate line GLi+1, but the invention is not limited thereto. In another embodiment of the invention, the control electrode of the seventh transistor TR7 may be connected to either the ith gate line GLi or the (i-1)th gate line GLi-1.

[0097] Capacitor CP is positioned between power line PL and node ND. Capacitor CP stores the voltage corresponding to the data signal. When the fifth transistor TR5 and the sixth transistor TR6 are turned on, the amount of current flowing through the first transistor TR1 can be determined based on the voltage stored in capacitor CP.

[0098] In this invention, the equivalent circuit of pixel PX is not limited to Figure 2b The equivalent circuit is shown. In another embodiment of the invention, the pixel PX can be implemented in various forms to make the light-emitting element EE emit light. Although Figure 2b The illustration is based on a PMOS, but is not limited thereto. In another embodiment of the invention, the pixel circuit CC can be configured as an NMOS. In yet another embodiment of the invention, the pixel circuit CC can be configured by a combination of NMOS and PMOS.

[0099] An input sensing unit 220 is disposed on the display panel 210. The input sensing unit 220 can sense external input TC (Tc). Figure 1a And obtain the input TC ( Figure 1a The input sensing unit 220 may include multiple sensing electrodes TX, RX, multiple sensing lines SL1, SL2, SL3, multiple first bridging patterns CP1, multiple second bridging patterns CP2, and multiple sensing pads PDT.

[0100] Multiple sensing electrodes TX and RX are arranged in the active region AA. The multiple sensing electrodes TX and RX may include multiple first sensing electrodes TX and multiple second sensing electrodes RX that receive different electrical signals from each other. The input sensing unit 220 can obtain information about the input TC provided to the active region AA by the change in capacitance between the first sensing electrodes TX and the second sensing electrodes RX.

[0101] The first sensing electrodes TX may include n first sensing electrodes TX1, TX2, TX3, ..., TXn, spaced apart from each other along the second direction DR2 and each extending along the first direction DR1. For convenience, the first sensing electrodes TX are defined below as arranged in n columns. Furthermore, considering the shape of the input sensing unit 220, n can be an integer greater than or equal to 5.

[0102] Each of the first sensing electrodes TX1, TX2, TX3, ..., TXn may include a plurality of first sensing patterns SP1 and a plurality of first connection patterns BP1 arranged along the first direction DR1.

[0103] The first sensing pattern SP1 and the first connecting pattern BP1 can be arranged alternately along the first direction DR1. Each of the first connecting patterns BP1 connects two adjacent patterns in the first sensing pattern SP1.

[0104] The second sensing electrodes RX may include m second sensing electrodes RX1, RX2, RX3, ..., RXm, spaced apart from each other along the first direction DR1 and each extending along the second direction DR2. For convenience, the second sensing electrodes RXm are defined below as arranged in m rows. Hereinafter, m can be an integer greater than 2.

[0105] The second sensing electrode RX can be insulated from the first sensing electrode TX.

[0106] The second sensing electrodes RX1, RX2, RX3, ..., RXm may include a plurality of second sensing patterns SP2 and a plurality of second connecting patterns BP2 arranged along the second direction DR2. The second sensing patterns SP2 and the second connecting patterns BP2 may be arranged alternately along the second direction DR2. Each of the second connecting patterns BP2 connects to two adjacent patterns in the second sensing patterns SP2.

[0107] In this embodiment, the first connection pattern BP1 and the second connection pattern BP2 can be arranged on different layers, while the first sensing pattern SP1 and the second sensing pattern SP2 can be arranged on the same layer. For example, the first connection pattern BP1 can be arranged on a different layer than the second connection pattern BP2, the first sensing pattern SP1, and the second sensing pattern SP2, while the second connection pattern BP2 can be arranged on the same layer as the first sensing pattern SP1 and the second sensing pattern SP2.

[0108] However, this is an exemplary illustration. The first connection pattern BP1 may also be arranged on the same layer as the first sensing pattern SP1 and the second sensing pattern SP2, or the first sensing electrode TX and the second sensing electrode RX may be arranged on different layers. It is not limited to any one embodiment.

[0109] The multiple sensing pads PDT may include multiple first pads T1 and multiple second pads T2. Each of the multiple first pads T1 and multiple second pads T2 may be configured to transmit an externally transmitted electrical signal to each of the first sensing electrode TX and the second sensing electrode RX.

[0110] Multiple sensing lines SL1, SL2, SL3 and sensing pads PDT are arranged in the surrounding area NAA. The sensing pads PDT are connected to the multiple sensing lines SL1, SL2, SL3. The multiple sensing lines SL1, SL2, SL3 include multiple first sensing lines SL1, multiple second sensing lines SL2, and multiple third sensing lines SL3. The first sensing lines SL1 are connected to one end of each of the first sensing electrodes TX1, TX2, TX3, ..., TXn. For example, Figure 2cThe diagram illustrates a first sensing line SL1 connected to one end of TXn-S1, TXn-S2, of the two ends of the first sensing electrodes TXn in the n columns.

[0111] The first sensing line SL1 connects the first pad T1 in the sensing pad PDT to the first sensing electrodes TX1, TX2, TX3, ..., TXn respectively, thereby transmitting the externally provided electrical signal to the first sensing electrodes TX1, TX2, TX3, ..., TXn.

[0112] The second sensing line SL2 is connected to the other end of each of the two ends of the first sensing electrodes TX1, TX2, TX3, ..., TXn. For example, Figure 2c The diagram illustrates a second sensing line SL2 connected to the other end TXn-S2 of the n-column first sensing electrodes TXn. The other end of the first sensing electrodes TX1, TX2, TX3, ..., TXn can be the portion facing one end of the first sensing electrodes TX1, TX2, TX3, ..., TXn. For example, one end TXn-S1 of the n-column first sensing electrodes TXn may face the other end TXn-S2.

[0113] In this invention, a first bridging pattern CP1 connects the first sensing line SL1 to each of the second sensing lines SL2. Specifically, the first sensing line SL1 can be connected to the second sensing line SL2 via the first bridging pattern CP1 to transmit electrical signals.

[0114] Similar to the first sensing electrodes TX1, TX2, TX3, ..., TXn, the first bridging pattern CP1 extends along the first direction DR1. Furthermore, each of the first sensing electrodes TX1, TX2, TX3, ..., TXn overlaps with the first bridging pattern CP1 in the first direction DR1. For example, referring to... Figure 2c The n-column first bridging pattern CP1_n can overlap with the n-column first sensing electrode TXn in the first direction DR1.

[0115] In one embodiment, each of the first bridging patterns CP1 may be arranged closer to one end of the first sensing electrodes TX1, TX2, TX3, ..., TXn than the other end of the first sensing electrodes TX1, TX2, TX3, ..., TXn. For example, referring to... Figure 2c The n-column first bridging pattern CP1_n can be arranged so that one end TXn-S1 is closer to the other end TXn-S2 of the two ends TXn-S1 and TXn-S2 of the n-column first sensing electrodes TXn. However, the embodiments are not limited to this.

[0116] In this invention, the second bridging pattern CP2 connects the first sensing line SL1 to each of the first pads T1. Specifically, the first sensing line SL1 can be connected to each of the first pads T1 via the second bridging pattern CP2, thereby receiving electrical signals provided from the outside.

[0117] The first pad T1 is arranged closer to the second bridging pattern CP2 than the first bridging pattern CP1. In one embodiment, an external electrical signal provided from the first pad T1 can be transmitted to the first sensing line SL1 through the second bridging pattern CP2. The external electrical signal received by the first sensing line SL1 can be transmitted to the second sensing line SL2 through the first bridging pattern CP1.

[0118] Accordingly, the second sensing line SL2 can transmit the same electrical signal as the first sensing line SL1 to the first sensing electrode TX.

[0119] The first sensing electrode TX, which has a relatively longer length than the second sensing electrode RX, is doubly connected to the first pad T1 via the first sensing line SL1 and the second sensing line SL2, thereby maintaining uniform sensitivity according to the region.

[0120] Furthermore, since the first sensing line SL1 and the second sensing line SL2 are connected by the first bridging pattern CP1, an input sensing unit 220 that provides uniform sensitivity across the entire surface of the active region AA can be achieved without increasing the sensing pad PDT.

[0121] In one embodiment, the first bridging pattern CP1 and the second bridging pattern CP2 may each comprise a transparent conductive oxide (TCO). For example, each of the first bridging pattern CP1 and the second bridging pattern CP2 may comprise indium tin oxide (ITO) or indium zinc oxide (IZO).

[0122] Additionally, the third sensing line SL3 is connected to one end of each of the second sensing electrodes RX1, RX2, RX3, ..., RXm. For example, Figure 2c The diagram illustrates a third sensing line SL3 connected to one end RXm-S1 of the two ends RXm-S2 of the m-row second sensing electrodes Rxm. One end of the second sensing electrodes RX1, RX2, RX3, ..., RXm can be a portion relatively adjacent to the sensing pad PDT. For example, one end RXm-S1 of the two ends RXm-S1 and RXm-S2 of the m-row second sensing electrodes Rxm can be arranged closer to the sensing pad PDT than the other end RXm-S2.

[0123] The third sensing line SL3 can connect the second pad T2 in the sensing pad PDT to the second sensing electrodes RX1, RX2, RX3, ..., RXm respectively. The electrical signal provided from the outside can be transmitted from the second pad T2 to the second sensing electrodes RX1, RX2, RX3, ..., RXm through the third sensing line SL3.

[0124] Figure 3a This is a magnified image. Figure 2c The diagram of the RR region. Figure 3b Is with Figure 3a The sectional view corresponding to I-I'. Figure 3c Is with Figure 3a The sectional view corresponding to II-II'. Figure 3d Is with Figure 3a The sectional view corresponding to III-III'.

[0125] In order to explain the multiple first sensing lines SL1, multiple second sensing lines SL2, multiple first bridging patterns CP1 and multiple second bridging patterns CP2, as an example, the n-1 columns of first bridging patterns CP1_n-1 will be explained.

[0126] Reference Figure 2c and Figure 3a The RR region can be the area where the first bridging pattern CP1_n-1 in column n-1 connects the first sensing line SL1_n-1 in column n-1 and the second sensing line SL2_n-1 in column n-1.

[0127] Furthermore, on the plane, the n-1 column of the first bridging pattern CP1_n-1 can overlap with the n-1 column of the first sensing line SL1_n-1, the n column of the first sensing line SL1_n, and the n-1 column of the second sensing line SL2_n-1.

[0128] For convenience, the first sensing line SL1_n-1 in column n-1 can be defined as the first front sensing line SL1-F_n-1 in column n-1 and the first rear sensing line SL1-T_n-1 in column n-1. The first rear sensing line SL1-T_n-1 in column n-1 can be a line extending from the first front sensing line SL1-F_n-1 in column n-1, and the first front sensing line SL1-F_n-1 and the first rear sensing line SL1-T_n-1 in column n-1 can be a single wiring.

[0129] The first front-end sensing line SL1-F_n-1 in column n-1 can extend along the first direction DR1, and the first rear-end sensing line SL1-T_n-1 in column n-1 can extend along the second direction DR2.

[0130] The intersection of the first front-end sensing line SL1-F_n-1 and the first rear-end sensing line SL1-T_n-1 in column n-1 can overlap with the first bridging pattern CP1_n-1 in column n-1.

[0131] In one embodiment, the n-1 column of first front-end sensing lines SL1-F_n-1 can be lines extending along the first direction DR1 and connecting the n-1 column of sensing electrodes TXn-1 and the n-1 column of first bridging patterns CP1_n-1.

[0132] In one embodiment, the n-1 column of first rear end sensing lines SL1-T_n-1 can be lines extending along the second direction DR2 to connect the n-1 column of first bridging patterns CP1_n-1 and their corresponding n-1 column of second bridging patterns.

[0133] See Figure 3b n-1 columns of first bridging patterns CP1_n-1 are arranged on the first sensing insulating layer 221, and n-1 columns of first sensing lines SL1_n-1 are arranged between the second sensing insulating layer 222 and the third sensing insulating layer 223. The n-1 columns of first sensing lines SL1_n-1 can be electrically connected to the n-1 columns of first bridging patterns CP1_n-1 through the first contact hole CT1.

[0134] Reference Figure 3a and Figure 3c The first rear end sensing line SL1-T_n-1 in column n-1 and the second sensing line SL2_n-1 in column n-1 can be arranged between the second sensing insulating layer 222 and the third sensing insulating layer 223.

[0135] In one embodiment, the n-1 column of first rear-end sensing lines SL1-T_n-1 can be electrically connected to the n-1 column of second sensing lines SL2_n-1. Specifically, the n-1 column of first rear-end sensing lines SL1-T_n-1 can be connected to the n-1 column of first bridging pattern CP1_n-1 through the first contact hole CT1, and the n-1 column of second sensing lines SL2_n-1 can be connected to the n-1 column of first bridging pattern CP1_n-1 through the second contact hole CT2.

[0136] That is, in this embodiment, the first rear-end sensing line can transmit the electrical signal received from the first pad T1 to each of the first front-end sensing line and the second sensing line SL2. Accordingly, in the input sensing unit 220 of one embodiment, the first sensing electrode TX is doubly connected to the first pad T1 through the first sensing line SL1 and the second sensing line SL2; however, only the first sensing line SL1 is directly connected to the first pad T1, thereby reducing the number of wires connected to the first pad T1.

[0137] Reference Figure 3dIn one embodiment, n-1 columns of first front-end sensing lines SL1-F_n-1, n columns of first front-end sensing lines, n-1 columns of second sensing lines SL2_n-1 and n-2 columns of second sensing lines SL2_n-2 can be arranged between the second sensing insulating layer 222 and the third sensing insulating layer 223.

[0138] The first sensing line SL1 and the second sensing line SL2 can be arranged on a different layer than the first bridging pattern CP1. Figures 3b to 3d The illustration shows a first sensing line SL1 and a second sensing line SL2 arranged on a second sensing insulating layer 222, and a first bridging pattern CP1 arranged on a first sensing insulating layer 221. However, it is not limited to this case. Alternatively, the first sensing line SL1 and the second sensing line SL2 can be arranged on a first sensing insulating layer 221, and the first bridging pattern CP1 can be arranged on a second sensing insulating layer 222.

[0139] Although not shown, the second bridging pattern CP2 can be disposed on the same layer as the first bridging pattern CP1. More specifically, the second bridging pattern CP2 can be disposed on the first sensing insulating layer 221, thereby connecting each of the first sensing line SL1 and the first pad T1.

[0140] Refer to together Figure 2c and Figure 3d The n-1 columns of first bridging patterns CP1_n-1 and the n columns of first sensing lines SL1_n overlap on a plane. However, the n columns of first sensing lines SL1_n and the n-1 columns of first bridging patterns CP1_n-1 are arranged on different layers with the second sensing insulating layer 222 placed between them, thus insulating the n columns of first sensing lines SL1_n and the n-1 columns of first bridging patterns CP1_n-1. Therefore, the n columns of first sensing lines SL1_n can be directly connected to the n columns of first sensing electrodes TXn and their corresponding first pads T1.

[0141] In addition, on the first bridging pattern CP1_n-1 in column n-1, the first sensing line SL1_n in column n-1 is arranged between the first front sensing line SL1-F_n-1 in column n-1 and the second sensing line SL2_n-1 in column n-1. Therefore, the length of the first bridging pattern CP1_n-1 in column n-1 can be greater than the length of the first bridging pattern CP1_n in column n-1.

[0142] exist Figures 3a to 3d Although the example uses columns n and n-1, this can be applied to different columns of each of the multiple first sensing lines SL1, multiple second sensing lines SL2, and multiple first bridging patterns CP1.

[0143] Figure 4a This is a magnified image. Figure 2c The diagram of the SS region. Figure 4bThis is a magnified image. Figure 2c A diagram of a modified embodiment of the SS region.

[0144] Refer to together Figure 2c and Figure 4a The SS region is the area illustrated by the second sensing line SL2_1, the second sensing line SL2_2, and the third sensing line SL2_3 connected to the other end of each of the first sensing electrode TX1, the second sensing electrode TX2, and the third sensing electrode TX3.

[0145] like Figure 2c As shown, the first sensing line SL1 can be connected to each of the first pads T1 via the second bridging pattern CP2, such that the first sensing line SL1 and the first, second, and third columns of second sensing lines SL2_1, SL2_2, and SL2_3 do not intersect each other. As described above, the second bridging pattern CP2 can be arranged below the first and second sensing lines SL1 and SL2. Therefore, the first sensing line SL1 and the first pad T1 can be connected to the second bridging pattern CP2 via contact holes (not shown).

[0146] To achieve the effect described above, the width of the second bridging pattern CP2 is adjusted to be greater than the sum of the widths of the first column of second sensing lines SL2_1, the second column of second sensing lines SL2_2, and the third column of second sensing lines SL2_3. Therefore, the smaller the width of each of the first column of second sensing lines SL2_1, the second column of second sensing lines SL2_2, and the third column of second sensing lines SL2_3, the smaller the width of the second bridging pattern CP2 can be.

[0147] For example, such as Figure 4a As shown, when each of the first, second, and third second sensing lines SL2_1, SL2_2, and SL2_3 has a row structure, the width of the second bridging pattern CP2 can be minimized.

[0148] However, the embodiments are not limited thereto. See also Figure 4b Each of the first column of second sensing lines SL2_1, the second column of second sensing lines SL2_2, and the third column of second sensing lines SL2_3 can have a structure in which two rows of wiring are connected by a third bridging pattern CP3.

[0149] For example, a column of second sensing lines SL2_1 may include a column of second sub-sensing lines SL2_11 and SL2_12. The column of second sub-sensing lines SL2_11 and SL2_12 can be connected to each other through a third bridging pattern CP3 to transmit the same signal.

[0150] In one embodiment, similar to the first bridging pattern CP1 and the second bridging pattern CP2, the third bridging pattern CP3 can be arranged on the lower layer of the first sensing line SL1 and the second sensing line SL2.

[0151] The two columns of second sensing lines SL2_2 may include two columns of second sub-sensing lines SL2_21 and SL_22. The three columns of second sensing lines SL2_3 may include three columns of second sub-sensing lines SL2_31 and SL2_32. Each of the two columns of second sub-sensing lines SL2_21 and SL_22 and the three columns of second sub-sensing lines SL2_31 and SL2_32 can be connected to each other through a third bridging pattern CP3.

[0152] Figure 5a This is a magnified image. Figure 2c The diagram of the TT region. Figure 5b Is with Figure 5a The sectional view corresponding to IV-IV'. Figure 5c It is a diagram and Figure 5a A diagram of a modified embodiment of the region corresponding to line IV-IV'.

[0153] Refer to together Figure 2c and Figure 5a The TT region can be the area where the first connecting pattern BP1 and the second connecting pattern BP2 intersect. For ease of explanation, Figure 5a The illustration shows two first sensing patterns SP11 and SP12 connected to a first connection pattern BP1 in a plurality of first sensing patterns SP1, and two second sensing patterns SP21 and SP22 connected to a second connection pattern BP2 in a plurality of second sensing patterns SP2.

[0154] Reference Figure 5a and Figure 5b The first sensing patterns SP11 and SP12 and the second sensing patterns SP21 and SP22 are arranged spaced apart from each other on a plane. The first sensing patterns SP11 and SP12 and the second sensing patterns SP21 and SP22 are arranged on the same layer. The first sensing patterns SP11 and SP12 are electrically insulated from the second sensing patterns SP21 and SP22. In this embodiment, the second sensing patterns SP21 and SP22 are illustrated to have a shape integral with the second connecting pattern BP2.

[0155] The first connecting pattern BP1 and the second connecting pattern BP2 may intersect each other on a plane. The first connecting pattern BP1 and the second connecting pattern BP2 may be arranged on different layers on a plane. The first connecting pattern BP1 may include multiple patterns BP11 and BP12 that are spaced apart from each other.

[0156] The first sensing patterns SP11 and SP12 can be interconnected by multiple patterns BP11 and BP12. Therefore, even if one of the multiple patterns BP11 and BP12 is damaged, the electrical connection between the first sensing patterns SP11 and SP12 can be stably maintained.

[0157] Each of the multiple patterns BP11 and BP12 may include a first part B1, a second part B2, and a third part B3. The first part B1 can connect any one SP11 of the first sensing patterns SP11 and SP12 to the second part B2, and the third part B3 can connect the other SP12 of the first sensing patterns SP11 and SP12 to the second part B2.

[0158] In one embodiment, the first portion B1 and the third portion B3 may be disposed between the second sensing insulating layer 222 and the third sensing insulating layer 223. The second portion B2 may be disposed between the first sensing insulating layer 221 and the second sensing insulating layer 222.

[0159] The first sensing patterns SP11 and SP12 can be arranged on the same layer as the second part B2. The first sensing patterns SP11 and SP12 and the second part B2 can be arranged separately from each other. The first part B1 and the third part B3 can penetrate the second sensing insulating layer 222 and be connected to the first sensing patterns SP11, SP12 and the second part B2.

[0160] Additionally, the second portion B2 can be arranged on the same layer as the second connecting pattern BP2. In this embodiment, the second portion B2 is arranged within a predetermined opening (not shown) defined in the second connecting pattern BP2. The second portion B2 is arranged separately from the second connecting pattern BP2 in a plane. The second portion B2 is electrically insulated from the second connecting pattern BP2.

[0161] In this embodiment, the first connection pattern BP1 and the second connection pattern BP2 can be formed using different materials. In this embodiment, the second portion B2 of the first connection pattern BP1 and the second connection pattern BP2 can be optically transparent. The first portion B1 and the third portion B3 of the first connection pattern BP1 can be optically opaque. Specifically, the second portion B2 and the second connection pattern BP2 can include transparent conductive oxide (TCO). For example, the second portion B2 and the second connection pattern BP2 can include indium tin oxide (ITO). The first portion B1 and the third portion B3 can include metals or conductive polymers.

[0162] However, this is an illustrative example. In an input sensing unit according to an embodiment of the present invention, the first connection pattern BP1 may be optically opaque, and the second connection pattern BP2 may be optically transparent. Alternatively, both the first connection pattern BP1 and the second connection pattern BP2 may be optically transparent or optically opaque, or the first connection pattern BP1 and the second connection pattern BP2 may be formed using the same material. An input sensing unit according to an embodiment of the present invention may include various embodiments and is not limited to any one embodiment.

[0163] Figure 5c This is a modified embodiment of the TT region. In this embodiment, the first portion B1 and the third portion B3 can be disposed between the first sensing insulating layer 221 and the second sensing insulating layer 222. The second portion B2 can be disposed between the second sensing insulating layer 222 and the third sensing insulating layer 223.

[0164] The first sensing patterns SP11 and SP12 can be arranged on the same layer as the second part B2. The first sensing patterns SP11 and SP12 and the second part B2 can be arranged separately from each other. The first sensing patterns SP11 and SP12 and the second part B2 can penetrate the second sensing insulating layer 222 and be connected to the first part B1 and the third part B3.

[0165] The input sensing unit according to the present invention can be provided in various shapes as long as the first sensing patterns SP11, SP12 and the second sensing patterns SP21, SP22 are electrically insulated, and is not limited to any one embodiment.

[0166] Figure 6a This is a plan view of an input sensing unit 220-1 according to an embodiment of the present invention. Figure 6b This is a magnified image. Figure 6a A diagram of a portion of the RR' region.

[0167] in addition, Figure 6a and Figure 6b As Figure 2c and Figure 3a In the modified embodiments, the same reference numerals are given to the same configurations as those described above, and detailed descriptions are omitted.

[0168] Reference Figure 6a and Figure 6b The RR' region can be the region where n columns of the first bridging pattern CP1'_n connect n columns of the first sensing line SL1_n and n columns of the second sensing line SL2_n.

[0169] The n-column first sensing line SL1_n can be defined by distinguishing it into n-column first front-end sensing lines SL1-F_n and n-column first rear-end sensing lines SL1-T_n. Therefore, Figure 2c The content described herein can be applied in the same way. Specifically, the n columns of first rear-end sensing lines SL1-T_n can connect the n columns of first bridging patterns CP1'_n and their corresponding n columns of second bridging patterns.

[0170] The n-column second sensing line SL2_n may include the n-column second front-end sensing line SL2-F_n and the n-column second rear-end sensing line SL2-T_n. The n-column second rear-end sensing line SL2-T_n may be a line extending from the n-column second front-end sensing line SL2-F_n, and the n-column second front-end sensing line SL2-F_n and the n-column second rear-end sensing line SL2-T_n may be a single wiring.

[0171] The n-column second rear end sensing line SL2-T_n can connect the n-column first bridging pattern CP1'_n and its corresponding n-column second bridging pattern.

[0172] Therefore, all n columns of first rear-end sensing lines SL1-T_n and n columns of second rear-end sensing lines SL2-T_n can be connected to the n columns of second bridging pattern. Even if any one of the n columns of first rear-end sensing lines SL1-T_n and n columns of second rear-end sensing lines SL2-T_n is damaged, the electrical connection between the first pad T1 and the first sensing electrode TX can be stably maintained.

[0173] Although described with reference to embodiments, those skilled in the art will understand that various modifications and alterations can be made to the invention without departing from the spirit and scope of the invention as set forth in the claims. Furthermore, the embodiments disclosed herein are not intended to limit the technical concept of the invention; the scope of the claims and all technical concepts within their equivalents should be understood as encompassed within the scope of the invention.
