[0053] Reference Figure 1 The electronic device 1000 may be a device activated by an electrical signal. For example, the electronic device 1000 may be a mobile phone, a tablet PC, a car navigation system, a game console, or a wearable device, but is not limited to these according to embodiments of this disclosure. Figure 1 An example of which electronic device 1000 is a mobile phone is shown.

The thickness direction of electronic device 1000 may be parallel to a third direction DR3, which intersects the first direction DR1 and the second direction DR2 (e.g., the third direction DR3 is perpendicular or orthogonal to the first direction DR1 and the second direction DR2). Therefore, the front (or top) and rear (or bottom) surfaces of each component constituting electronic device 1000 may be defined based on the third direction DR3.

[0055] The electronic device 1000 can sense input applied from outside itself. External input can be user input. User input can include various types of external input, such as a part of the user's body, light, heat, or pressure.

[0093] The sensor layer 200 can be positioned on the display layer 100 via a continuous process. In this case, the sensor layer 200 can be represented as being directly disposed on the display layer 100. Direct disposal can mean that a third component is not positioned between the sensor layer 200 and the display layer 100. That is, a separate adhesive member may not be positioned between the sensor layer 200 and the display layer 100. In this case, the thickness of the electronic device 1000 can be relatively thin.

[0097] The conductive layer having a single-layer structure may include a metal layer or a transparent conductive layer. The metal layer may include molybdenum, silver, titanium, copper, aluminum, or alloys thereof. The transparent conductive layer may include transparent conductive oxides such as indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), and indium zinc tin oxide (IZTO). Alternatively, the transparent conductive layer may include conductive polymers such as PEDOT, metal nanowires, and graphene.

[0098] A conductive layer with a multilayer structure may include a metal layer. The metal layer may have a titanium / aluminum / titanium three-layer structure. A conductive layer with a multilayer structure may include at least one metal layer and at least one transparent conductive layer.

[0099] At least one of the sensing insulating layer 203 and the covering insulating layer 205 may include an inorganic layer. The inorganic layer may include at least one of alumina, titanium oxide, silicon oxide, silicon oxynitride, zirconium oxide, and hafnium oxide.

[0100] Parasitic capacitance Cb can be generated between sensor layer 200 and second electrode CE. As the distance between sensor layer 200 and second electrode CE becomes closer, the value of parasitic capacitance Cb increases. As parasitic capacitance Cb increases, the ratio of the change in capacitance to a reference value decreases. The change in capacitance can refer to the capacitance through an input unit (e.g., input device 2000, see reference CE). Figure 2 ) or the user's body 3000 (see Figure 2 The change in capacitance that occurs before and after the input.

[0101] The driver chip that processes the signal sensed by sensor layer 200 can perform a leveling operation (or calibration operation) to remove the value corresponding to the parasitic capacitance Cb from the sensed signal. The ratio of the capacitance change to the reference value can be increased by the leveling operation to improve sensing sensitivity.

[0102] However, the ability to remove the value corresponding to the parasitic capacitance Cb varies depending on the specifications of the driver chip. For example, if the maximum parasitic capacitance Cb is about 500 picofarads, and the capacitance value that can be removed from the signal sensed by the sensor layer 200 through the driver chip is about 200 picofarads, the reference value will not be sufficiently reduced by the driver chip. In this case, the change in capacitance is not significant compared to the reference value, and therefore, a failure may occur where the driver chip cannot recognize the change in capacitance as noise or cannot recognize the touch coordinates. According to the inventive concept, the electrode structure of the sensor layer 200 can be modified to provide a maximum value of parasitic capacitance Cb as a fixed value (e.g., a set value or a predetermined value) or smaller. In this case, the accuracy of coordinate recognition can be improved even when the performance of the driver chip is relatively low. This fixed value (e.g., a set value or a predetermined value) can be about 200 picofarads, but is not particularly limited thereto.

[0133] exist Figure 5B In the process, bridging pattern 212B may have a bottom bridging structure in which bridging pattern 212B is positioned below the first cross pattern 212PT1, the second cross pattern 212PT2, and the electrode 211, but according to some embodiments of the inventive concept, the sensor layer 200 (see Figure 4 The structure of the sensor layer 200 is not limited thereto. For example, according to some embodiments of the inventive concept, the sensor layer 200 (see Figure 4 It may have a top bridging structure in which the bridging pattern 212B is positioned on the first cross pattern 212PT1, the second cross pattern 212PT2 and the electrode 211.

[0134] Electrode 211, cross electrode 212, and multiple dummy electrodes 213 can have a mesh structure. Figure 5C In the middle, a portion of the second cross pattern 212PT2, a portion of the electrode 211, and a portion of the plurality of dummy electrodes 213 are in Figure 5C The example is shown below. The opening OP defined by the mesh structure can be connected to the emission region PXA (see example). Figure 3 Stacked.

[0135] According to the inventive concept, a plurality of second portions 211P2, a plurality of second intersecting portions 212P2, and a plurality of third portions 211P3 can be positioned adjacent to each other. The plurality of second portions 211P2, the plurality of second intersecting portions 212P2, and the plurality of third portions 211P3 can have an interdigitated (or alternate, staggered) shape. The length of the boundary facing each other for each of the plurality of second portions 211P2, each of the plurality of second intersecting portions 212P2, and each of the plurality of third portions 211P3 can be increased. Therefore, the mutual capacitance between electrode 211 and the intersecting electrode 212 can be increased. Furthermore, in the user's body 3000 (see...) Figure 2 The change in mutual capacitance before and after the input can be increased. Therefore, the sensor layer 200 (see...) can be improved. Figure 4 ) sensing sensitivity.

[0136] When viewed on a plane, the outermost part of the electrode region BD1, defined by a plurality of second portions 211P2, a plurality of second intersection portions 212P2, and a plurality of third portions 211P3, can have an octagonal shape. For example, the outermost part of the region defined by a plurality of second portions 211P2 surrounding the plurality of second intersection portions 212P2 and the plurality of third portions 211P3 can have an octagonal shape.

[0137] When the region where electrodes 211 and cross electrodes 212 intersect and insulate each other has a rectangular shape by means of portions extending in the first direction DR1 and the second direction DR2 respectively, the spacing between electrodes 211 and cross electrodes 212 increases in the region where the direction of the extension changes from the first direction DR1 to the second direction DR2, thus increasing the deviation in the spacing between electrodes 211 and cross electrodes 212. However, according to the inventive concept, the electrode region BD1 where electrodes 211 and cross electrodes 212 intersect and insulate each other can have an octagonal shape by means of portions extending in the first direction DR1, the second direction DR2, the first cross direction DRa, and the second cross direction DRb respectively. This reduces the deviation in the spacing between electrodes 211 and cross electrodes 212. Therefore, the deviation in the spacing between electrodes 211 and cross electrodes 212 can be reduced. Figure 2 The change in mutual capacitance between electrode 211 and cross electrode 212 before and after input is determined according to the user's body 3000 (see...). Figure 2 The deviation in position of ) can therefore improve the user's body 3000 (see Figure 2 The input uses sensor layer 200 (see) Figure 4 The accuracy of the calculated coordinates can be improved. Furthermore, the sensor layer 200 (see...) can be improved. Figure 4 ) sensing reliability.

[0138] Furthermore, according to the inventive concept, the deviation in the spacing between electrode 211 and cross electrode 212 can be reduced. This can reduce the impact on the sensing input device 2000 (see...). Figure 2 Each of the preceding and following electrodes 211 and the cross electrode 212 is connected to the input device 2000 (see...). Figure 2 The change in mutual capacitance between them is based on the input device 2000 (see...). Figure 2 The positional deviation of the input device 2000 (see [reference]) can be corrected. Figure 2 The use of sensor layer 200 (see) Figure 4 The accuracy of the calculated sensing coordinates can be improved. Furthermore, the sensor layer 200 (see...) can be improved. Figure 4 ) sensing reliability.

[0139] That is, it can prevent (such as when using input device 2000 (see...)) Figure 2 When writing letters or drawing pictures, the changes in capacitance measured within a sensing unit 210 in the input provided in the form of lines are different from each other. Therefore, the linearity of the input can be improved, and the sensor layer 200 (see...) can be improved. Figure 4 ) sensing reliability.

[0140] Multiple dummy electrodes 213 may be arranged around electrode 211 and cross electrode 212, respectively. When multiple dummy electrodes 213 are arranged, the difference in transmittance or reflectance between the portions on which electrode 211 or cross electrode 212 is not positioned can be reduced. Therefore, it is possible to prevent the visual identification of certain boundaries (e.g., the boundary between electrode 211 and cross electrode 212 or the boundary between the portions on which electrode 211 and cross electrode 212 are not positioned) from being visually identified.

[0141] Multiple dummy electrodes 213 can be in a floating state. The floating of multiple dummy electrodes 213 reduces the size of sensor layer 200 (see...). Figure 3 ) and the second electrode CE (see Figure 3 The parasitic capacitance Cb generated between them (see) Figure 3 According to some embodiments of the inventive concept, sensor layer 200 (see...) Figure 3 The parasitic capacitance Cb (see...) Figure 3 The maximum value is provided as a certain value (e.g., a set or predetermined value) or smaller. The ratio of the change in capacitance to a reference value can be increased. Therefore, the sensor layer 200 (see...) can be improved. Figure 3 Sensitivity relative to changes in capacitance.

Figure 2 The signals Sa and Sb provided by the sensor driver SC are supplied to the receiving electrode of the sensor driver SC. In this case, signals Sa and Sb can be referred to as downlink signals. However, this is merely an example. For example, the operation of signals Sa and Sb according to some embodiments of the inventive concept is not limited thereto. For example, in a second mode, each of the plurality of electrodes 211 and the plurality of cross electrodes 212 can be used for providing signals Sa and Sb from the sensor driver SC to the input device 2000 (see [link to inventive concept]).

[0293] Reference Figure 4 and Figure 14C Multiple sensing units 210 can be positioned within the effective area 200A. One sensing unit 210 may include four sub-sensing units 210Ai.

[0294] The multiple lines 220 may include multiple first lines 221 and multiple second lines 222 electrically connected to multiple sub-sensing units 210Ai. Each of the multiple first lines 221 may be connected to two sub-sensing units 210Ai, and each of the multiple second lines 222 may be connected to two sub-sensing units 210Ai.

[0295] According to some embodiments of the inventive concept, a single line 220 can connect to multiple sub-sensing units 210Ai. Even if a sensing unit is divided into multiple sub-sensing units, the number of lines required to provide signals to the sensor layer 200 can be the same as the number of lines when a sensing unit is not divided into multiple sub-sensing units. In this case, since no additional lines are required, the surface area of ​​the peripheral region 200N does not need to be increased. Therefore, a narrow bezel can be achieved.

[0297] Reference Figure 4 and Figure 14D Multiple sensing units 210 can be positioned within the effective area 200A. One sensing unit 210 may include 16 sub-sensing units 210Aj.

[0298] The multiple lines 220 may include multiple first lines 221 and multiple second lines 222 electrically connected to multiple sub-sensing units 210Aj. Each of the multiple first lines 221 may be connected to four sub-sensing units 210Aj. Each of the multiple second lines 222 may be connected to four sub-sensing units 210Aj.

[0299] According to some embodiments of the inventive concept, a single line 220 can connect to multiple sub-sensing units 210Aj. Even if a sensing unit is divided into multiple sub-sensing units, the number of lines required to provide a signal to the sensor layer 200 can be the same as the number of lines when a sensing unit is not divided into multiple sub-sensing units. In this case, since no additional lines are required, the surface area of ​​the peripheral region 200N does not need to be increased. Therefore, a narrow bezel can be achieved.

[0300] According to some embodiments of the inventive concept, the electronic device may include a display layer and a sensor layer. The sensor layer may include electrodes and cross electrodes. The electrodes and cross electrodes may be positioned adjacent to each other. A portion of the electrodes and a portion of the cross electrodes may have an interdigitated shape. The length of the boundary where a portion of the electrodes and a portion of the cross electrodes face each other may be increased. Therefore, the mutual capacitance between the electrodes and the cross electrodes may be increased. In addition, the amount of change in mutual capacitance before and after user input may be increased. Therefore, the sensing sensitivity of the sensor layer may be improved.

[0301] According to some embodiments of the inventive concept, the areas where the electrodes and cross electrodes intersect or intersect each other in a planar view while remaining insulated from each other can have an octagonal shape through portions extending in a first direction, a second direction, a first cross direction, and a second cross direction, respectively. This can reduce the deviation in the spacing between the electrodes and cross electrodes. It can also reduce the deviation in the amount of change in mutual capacitance between the electrodes and cross electrodes before and after the user's input, depending on the position of the user's input. Furthermore, it can reduce the deviation in the amount of change in capacitance between each of the electrodes and cross electrodes and the input device. Therefore, the accuracy of each of the coordinates calculated using the sensor layer and the coordinates of the input device can be improved, and the sensing reliability of the sensor layer can be improved.

[0302] It will be apparent to those skilled in the art that various modifications and deviations can be made to the inventive concept. Therefore, this disclosure is intended to cover modifications and deviations of the invention, provided they fall within the scope of the appended claims and their equivalents. Thus, the true scope of protection of the inventive concept should be determined by the technical scope of the appended claims and their equivalents.
