[0078] Figure 1 is a perspective view showing an electronic device according to an exemplary embodiment of the present disclosure, and Figure 2 is a diagram showing an exemplary embodiment according to the present disclosure Figure 1 In the following, reference will be made to Figure 1 to Figure 2 An electronic device according to an exemplary embodiment of the present disclosure is described.
[0079] Reference Figure 1 , the electronic device according to the present exemplary embodiment may be the electronic watch 1000. According to another embodiment, the electronic device may be an electronic device that displays an image, for example, a mobile phone, a tablet computer, a monitor, a head-mounted display, a television, and the like.
[0080] The electronic watch 1000 may include a watch assembly 900 and a tape STR. The watch assembly 900 displays an image IM having predetermined information in a first direction DR1. In the present disclosure, the first direction DR1 may be referred to as a vertical direction or a thickness direction, for example, along a normal line of a face of the watch assembly 900. The image IM may include, for example, an image implementing a conventional analog watch, such as a clock hand indicating the current time, an icon of an application executed by an application processor, or an execution screen of an application.
[0081] The watch assembly 900 is attachable to and detachable from the band STR. The user can wear the band STR on his / her wrist to wear the electronic watch 1000 on the wrist. The use of the band STR should not be limited to the user's wrist. That is, the shape of the band STR can be modified so as to be worn on the user's arm or placed around the user's neck, or the band STR can be used to replace the watch stand for mounting the watch assembly 900 to another electronic device.
[0082] like Figure 2 As shown, the watch assembly 900 may include a display module 200 and an electronic module 100. The display module 200 includes a display panel 400 and a touch module 800. In this exemplary embodiment, the touch module 800 may be omitted. The touch module 800 may be integrally provided with the display module 200 or replaced with a keyboard.
[0083] Display module 200 generates Figure 1 The image IM shown. The display module 200 may include, for example, an organic light emitting display panel, a liquid crystal display panel, or an electrophoretic display panel. The touch module 800 senses external input. The external input may be a touch event or a hovering event generated by a user's finger or a stylus. The touch module 800 should not be limited to or thereby. That is, the touch module 800 may be an electrostatic capacitive touch module, an acoustic wave touch module, or an optical touch module.
[0084] The electronic module 100 may include various functional modules to operate the watch assembly 900. The electronic module 100 may include at least one of the following: a control module 10, a wireless communication module 20, an image input module 30, a sound input module 40, a sound output module 50, a memory 60, an external interface 70, a power module 80, and a camera module 90. The modules are mounted on a printed circuit board and are electrically connected to each other through a flexible printed circuit board.
[0085] The control module 10 controls the overall operation of the electronic watch 1000 and processes data. For example, the control module 10 activates or deactivates the display module 200, and outputs input image data to the display module 200. The control module 10 activates or deactivates the touch module 800, and controls the display module 200, the image input module 30, the sound input module 40, and the sound output module 50.
[0086] The wireless communication module 20 uses Bluetooth or WiFi connection to send and receive wireless signals to and from another terminal. The wireless communication module 20 uses a universal communication line to send and receive sound signals. The wireless communication module 20 includes a transmitter 24 that sends a signal after modulating the signal, and a receiver 22 that demodulates the signal applied thereto.
[0087] The image input module 30 processes the input image data to convert the input image data into image data that can be displayed by the display module 200. The sound input module 40 receives an external sound signal through a microphone during a recording mode or a voice recognition mode, and converts the sound signal into electrical sound data. The sound output module 50 converts the sound data provided from the wireless communication module 20 or the sound data stored in the memory 60, and outputs the converted sound data to the outside.
[0088] The external interface 70 serves as an interface to an external charger, a wired / wireless data port, a card slot (eg, a memory card, a SIM / UIM card, etc.) The power module 80 supplies power required for the overall operation of the watch assembly 900 .
[0089] Figure 3 is an exploded cross-sectional view showing an electronic watch according to an exemplary embodiment of the present disclosure.
[0090] Reference Figure 3 , the display module 200 of the watch assembly 900 can be connected to the belt STR so as to be attachable to and detachable from the belt STR. In more detail, a connection space CS is defined in the belt STR, and the display module 200 is accommodated in the connection space CS of the belt STR. In the present exemplary embodiment, the display module 200 may include an electronic module substrate 110, a window member 300, a display panel 400, and a housing 500.
[0091] The electronic module substrate 110 may be, but is not limited to, a printed circuit board, and various electronic components may be mounted on the electronic module substrate 110 to implement the electronic module 100 (see Figure 2 For example, the electronic module substrate 110 may include passive elements (eg, capacitors, resistors, etc.), active elements (eg, a microprocessor including an integrated circuit, a memory chip, etc.), and wires connecting the above elements.
[0092] In the present exemplary embodiment, the housing 500 accommodates the display panel 400 and the electronic module substrate 110 so as to protect the display panel 400 and the electronic module substrate 110 from external impact. An accommodating space 510 is defined in the housing 500, and the display panel 400 and the electronic module substrate 110 are accommodated in the accommodating space 510. The housing 500 is accommodated in the coupling space CS with STR to couple the display panel 400 and the electronic module substrate 110.
[0093] The display panel 400 displays an image in a first direction DR1. The display panel 400 may include a first display area DA1, and a second display area DA2 that is distinguished from the first display area DA1 in a horizontal direction, for example, the first display area DA1 and the second display area DA2 are adjacent to each other in the horizontal direction. In the present disclosure, the term "plane" used herein means an imaginary surface perpendicular to the first direction DR1, and the term "horizontal direction" used herein means a direction substantially parallel to the plane. When viewed in a plan view, the first display area DA1 surrounds the second display area DA2. The first display area DA1 displays an image IM (see Figure 1 ), and the second display area DA2 displays a second partial image PI2 of the image IM.
[0094] The window member 300 is disposed on the display panel 400. The window member 300 is coupled to the housing 500 to define a receiving space 510, or is coupled to the display panel 400 through an adhesive member.
[0095] The window member 300 includes a transparent material that transmits the first partial image PI1 and the second partial image PI2. The window member 300 includes a rigid glass material or a transparent polymer having flexibility.
[0096] The window member 300 includes a first window area WA1 and a second window area WA2 horizontally separated from the first window area WA1. The first and second window areas WA1 and WA2 overlap the first and second display areas DA1 and DA2, respectively, in the first direction DR1.
[0097] In this exemplary embodiment, the window member 300 has a dome shape. The window member 300 includes a flat lower surface and a convex upper surface. When viewed in a plan view, the window member 300 has an elliptical shape or a substantially circular shape. The upper surface of the window member 300 may be, but is not limited to, a two-dimensional curved surface. In other words, the upper surface of the window member 300 may be curved in at least two directions substantially parallel to the plane surface. Since the window member 300 has a dome shape, the electronic watch 1000 provides the user with an image having an improved three-dimensional effect, a sense of immersion (or immersion) and image fidelity.
[0098] When viewed in a plan view, the first window area WA1 is defined to be further outward than the second window area WA2. The first window area WA1 is defined at the edge of the window member 300, and the second window area WA2 is defined at the center of the window member 300. For example, the first window area WA1 and the second window area WA2 may be concentric, and the first window area WA1 may be outside the second window area WA2 and, for example, completely surround the second window area WA2. Since the window member 300 has a dome shape, the second thickness of the second window area WA2 is thicker than the first thickness of the first window area WA1.
[0099] The first partial image PI1 and the second partial image PI2 are transmitted through the first window area WA1 and the second window area WA2. Since the first window area WA1 and the second window area WA2 have convex upper surfaces, the first partial image PI1 and the second partial image PI2 are enlarged by the first window area WA1 and the second window area WA2. In more detail, the first window area WA1 enlarges the first partial image PI1 by M1 times, and the second window area WA2 enlarges the second partial image PI2 by M2 times. Since the second window area WA2 is defined at the center, "M2" is greater than "M1". Each of M1 and M2 is greater than zero (0). In the present exemplary embodiment, the first partial image PI1 and the second partial image PI2 are enlarged or reduced depending on the thickness, refractive index and curvature of the window member 300, and therefore the first partial image PI1 and the second partial image PI2 may be distorted. However, as described later, the display panel 400 according to the present exemplary embodiment prevents the first partial image PI1 and the second partial image PI2 from being distorted by the window member 300.
[0100] Figure 4 is a cross-sectional view showing a display module according to an exemplary embodiment of the present disclosure.
[0101] See also Figure 4 , the display panel 400 may include a base layer 410 and pixels disposed on the base layer 410. In the present exemplary embodiment, the pixels include a first pixel PX1 disposed in the first display area DA1, and a second pixel PX2 disposed in the second display area DA2.
[0102] The second pixel PX2 is smaller in size than the first pixel PX1. Figure 4As shown, the first length L1 of the first pixel PX1 in the horizontal direction is longer than the second length L2 of the second pixel PX2 in the horizontal direction. In the present exemplary embodiment, the first distance P1 in the horizontal direction between the first pixels PX1 adjacent to each other may be greater than the second distance P2 in the horizontal direction between the second pixels PX2 adjacent to each other. However, according to an embodiment, the first distance P1 may be equal to the second distance P2. Since the second length L2 is less than the first length L1, the second partial image PI2 is relatively reduced when displayed when compared with the first partial image PI1. Therefore, when the first partial image PI1 and the second partial image PI2 are transmitted through the window member 300, image distortion caused by the second partial image PI2 being magnified more than the first partial image PI1 can be prevented, and thus the display quality of the display module 200 can be improved.
[0103] In the present exemplary embodiment, the number of the second pixels PX2 per unit area of the second display area DA2 (hereinafter referred to as the pixel number PN2) may be greater than the number of the first pixels PX1 per unit area of the first display area DA1 (hereinafter referred to as the pixel number PN1). Therefore, the area of the display panel 400 through which the second partial image PI2 is displayed is relatively smaller than the area of the second partial image PI2. Therefore, image distortion caused by the second partial image PI2 being magnified more than the first partial image PI1 can be prevented, and thus the display quality of the display module 200 can be improved.
[0104] In the present exemplary embodiment, the following equation may be satisfied: PN2 / PN1=M2 / M1. The image enlargement is proportional to the ratio M1 and M2 of the first window area WA1 and the second window area WA2, and is inversely proportional to the number of pixels per unit area of the first display area DA1 and the second display area DA2. Therefore, when the above equation is satisfied, image distortion may be effectively prevented.
[0105] The first image data ID1 is provided to the first display area DA1. The first image data ID1 includes data provided to the first pixel PX1 to display the first partial image PI1. The second image data ID2 is provided to the second display area DA2. The second image data ID2 includes data provided to the second pixel PX2 to display the second partial image PI2.
[0106] In this exemplary embodiment, the display module 200 may further include a controller. The controller is disposed on the base layer 410 or on the display printed circuit board 205 (see Fig.19 ). The controller is controlled from the control module 10 (see Figure 2) receives first input image data having information about a first partial image PI1, and second input image data having information about a second partial image PI2, and compensates for the grayscale values of the first input image data and / or the second input image data to generate first image data ID1 and second image data ID2, thereby compensating for a brightness difference between a first pixel PX1 and a second pixel PX2, the brightness difference being caused by a size difference between the first pixel PX1 and the second pixel PX2. For example, since the size of the first pixel PX1 is larger than the size of the second pixel PX2, the brightness of an image (or light) displayed in the first pixel PX1 may be higher than the brightness of an image displayed in the second pixel PX2 with the same grayscale value. Therefore, the controller relatively increases the grayscale value of the second input image data and generates the second image data ID2 to prevent image distortion caused by uneven brightness. Therefore, the brightness difference caused by the size difference between the first pixel PX1 and the second pixel PX2 may be reduced, and thus the brightness of the first pixel PX1 and the second pixel PX2 may be uniform.
[0107] In the above description, it has been described that the first partial image PI1 and the second partial image PI2 (reference Figure 3 ) The display panel 400 may be distorted due to a thickness difference of the window member 300, but the above-described embodiments and the embodiments described below should not be limited to the display panel 400. The first partial image PI1 and the second partial image PI2 are enlarged or reduced by the thickness, refractive index, and curvature of the window member 300. Therefore, the display panel 400 may be deformed in various shapes to prevent the first partial image PI1 and the second partial image PI2 from being distorted due to the thickness, refractive index, and curvature of the window member 300.

In the present exemplary embodiment, the ratio between the areas of the first to third subpixels SPX1 to SPX3 of the second pixel PX2 and the areas of the first to third subpixels SPX1 to SPX3 of the first pixel PX1 may be substantially equal to the ratio between the areas of the second pixel PX2 and the areas of the first pixel PX1.

[0137] Each of the lower electrode LE and the upper electrode UE may include a conductive material. In more detail, each of the lower electrode LE and the upper electrode UE may be a transparent electrode, a semi-transparent electrode, or an opaque electrode (or a reflective electrode). In addition, each of the lower electrode LE and the upper electrode UE may have a single-layer structure of a single material or a plurality of different materials, or a multi-layer structure of layers formed of different materials.
[0138] When each of the upper electrode UE and the lower electrode LE is a transparent electrode or a semi-transparent electrode, each of the upper electrode UE and the lower electrode LE may include, for example, Li, Ca, LiF / Ca, LiF / Al, Al, Mg, BaF, Ba, Ag, compounds thereof, or mixtures thereof (e.g., a mixture of Ag and Mg), each of which is optically thin; or a transparent metal oxide (e.g., indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium tin zinc oxide (ITZO)), Mo, Ti, etc. When each of the upper electrode UE and the lower electrode LE is a reflective electrode, each of the upper electrode UE and the lower electrode LE may include, for example, Ag, Mg, Cu, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca, LiF / Ca, LiF / Al, Mo, Ti, compounds thereof, or mixtures thereof (e.g., a mixture of Ag and Mg), each of which is optically thick.
[0139] In the present exemplary embodiment, the first sub-pixel SPX1 may be a rear surface light-emitting type or a front surface light-emitting type. In the case where the first sub-pixel SPX1 is a rear surface light-emitting type, the lower electrode LE may be a transparent or semi-transparent electrode, the upper electrode UE may be a reflective electrode, and red light may leave to the outside through the lower electrode LE. In the case where the first sub-pixel SPX1 is a front surface light-emitting type, the lower electrode LE may be a reflective electrode, the upper electrode UE may be a transparent or semi-transparent electrode, and light may leave to the outside through the upper electrode UE.
[0140] In the present exemplary embodiment, the first sub-pixel SPX1 may have a non-inversion structure or an inversion structure. In the case where the first sub-pixel SPX1 has a non-inversion structure, the lower electrode LE is an anode, the upper electrode UE is a cathode, and the voltage applied to the lower electrode LE is higher than the voltage applied to the upper electrode UE. In contrast, in the case where the first sub-pixel SPX1 has an inversion structure, the lower electrode LE is a cathode, the upper electrode UE is an anode, and the voltage applied to the lower electrode LE is lower than the voltage applied to the upper electrode UE.

The first subpixel SPX1 may be, for example, a red subpixel, and the organic light emitting layer OL may include a red organic light emitting layer.
[0143] Fig.11A and Fig. 11B is a plan view showing a first pixel and a second pixel according to an exemplary embodiment of the present disclosure, and Fig. 12A and Fig. 12B are respectively along Fig.11A and Fig. 11B Cross-sectional views taken along lines II' and II-II' are shown.
[0144] See also Fig.11A and Fig. 11B , each of the first to third sub-pixels SPX1 to SPX3 of the first pixel PX1 and the second pixel PX2 may include a sub-light emitting area defined therein. In more detail, the first to third sub-light emitting areas SEA1 to SEA3 are defined in the first to third sub-pixels SPX1 to SPX3, respectively. In the present exemplary embodiment, the area of the light emitting area may be defined by the sub-light emitting area of each pixel.
[0145] In more detail, the first to third sub-light emitting areas SEA1 to SEA3 of the first pixel PX1 may form a first light emitting area of the first pixel PX1, and the sum of the areas of the first to third sub-light emitting areas SEA1 to SEA3 of the first pixel PX1 may be defined as the area of the first light emitting area. Similarly, the first to third sub-light emitting areas SEA1 to SEA3 of the second pixel PX2 may form a second light emitting area of the second pixel PX2, and the sum of the areas of the first to third sub-light emitting areas SEA1 to SEA3 of the second pixel PX2 may be defined as the area of the second light emitting area.
[0146] In the present exemplary embodiment, the inequality: (ES1 / PS1)<(ES2 / PS2) may be satisfied. "PS1" represents a first pixel area, "ES1" represents an area of a first light emitting region of the first pixel PX1, "PS2" represents a second pixel area, and "ES2" represents an area of a second light emitting region of the second pixel PX2. In other words, in the case of a ratio of a light emitting area to a pixel area, the second light emitting area ratio of the second pixel PX2 may be greater than the first light emitting area ratio of the first pixel PX1.
[0147] Therefore, the area difference between the first and second light emitting regions is reduced, and thus the brightness difference caused by the difference between the first and second pixel areas can be reduced. Therefore, the brightness of the first and second pixels PX1 and PX2 becomes uniform.
[0148] See also Fig. 12A and Fig. 12B , the first pixel PX1 and the second pixel PX2 include a first black matrix BM1 and a second black matrix BM2, respectively. The first black matrix BM1 overlaps the first pixel PX1 in the first direction DR1, and defines first to third sub-light emitting areas SEA1 to SEA3 of the first pixel PX1. The second black matrix BM2 overlaps the second pixel PX2 in the first direction DR1, and defines first to third sub-light emitting areas SEA1 to SEA3 of the second pixel PX2. In the present exemplary embodiment, the first black matrix BM1 has an area greater than that of the second black matrix BM2.
[0149] In this exemplary embodiment, the radial direction of the first black matrix BM1 is The first width on the black matrix BM2 is greater than the radial direction of the second black matrix BM2. The first width of the first black matrix BM1 is equal to the second width of the first black matrix BM1 in the radial direction. The sum of the widths Lb1 and Lb2 of the portions facing each other on the first black matrix BM1 corresponds to that of the first sub-light emitting area SEA1 of the first pixel PX1. Similarly, the second width of the second black matrix BM2 corresponds to the width of the second black matrix BM2 in the radial direction. The sum of the widths Lb3 and Lb4 of the portions facing each other on the upper side corresponds to each other, so that the first sub light emitting area SEA1 of the second pixel PX2 is disposed between the portions of the second black matrix BM2.
[0150] In this exemplary embodiment, the tangential direction of the first black matrix BM1 is The third width on the upper side is substantially equal to the tangential direction of the second black matrix BM2. The third width corresponds to the sum of widths Lc1 to Lc4 of a portion of the first black matrix BM1 overlapping the imaginary line IML1 that passes through the first pixel PX1 and is substantially parallel to the tangential direction. Similarly, the fourth width corresponds to the sum of the widths Lc5 to Lc8 of the portion of the second black matrix BM2 overlapping the imaginary line IML2 that passes through the second pixel PX2 and is substantially parallel to the tangential direction. In addition, the third width may be a tangential direction of the first black matrix BM1 disposed between sub-pixels adjacent to each other among the first to third sub-pixels SPX1 to SPX3 of the first pixel PX1. The fourth width may be a tangential direction of the second black matrix BM2 between adjacent sub-pixels in the first to third sub-pixels SPX1 to SPX3 of the second pixel PX2. The width on (i.e., one of Lc5, Lc6, Lc7 and Lc8).
[0151] like Fig. 12A and Fig. 12B As shown, the first pixel PX1 includes a first pixel defining layer PDL1. The first pixel defining layer PDL1 defines first to third sub-light emitting areas SEA1 to SEA3 of the first pixel PX1. In more detail, since only a portion of the organic light emitting layer OL corresponding to the lower electrode LE1 exposed and not covered by the first pixel defining layer PDL1 emits light, the first to third sub-light emitting areas SEA1 to SEA3 may be defined to correspond to the lower electrode LE1 exposed and not covered by the first pixel defining layer PDL1. In other words, the first pixel defining layer PDL1 may expose the lower electrode LE1 through the first light emitting area.
[0152] Similarly, the second pixel PX2 includes a second pixel defining layer PDL2. The second pixel defining layer PDL2 defines first to third sub-light emitting areas SEA1 to SEA3 of the second pixel PX2. In more detail, since only a portion of the organic light emitting layer OL corresponding to the lower electrode LE2 exposed and not covered by the second pixel defining layer PDL2 emits light, the first to third sub-light emitting areas SEA1 to SEA3 may be defined to correspond to the lower electrode LE2 exposed and not covered by the second pixel defining layer PDL2. In other words, the second pixel defining layer PDL2 may expose the lower electrode LE2 through the second light emitting area.
[0153] In the present exemplary embodiment, the first pixel defining layer PDL1 has an area larger than that of the second pixel defining layer PDL2. In addition, the ratio of the area of the first pixel defining layer PDL1 to the first pixel area may be greater than the ratio of the area of the second pixel defining layer PDL2 to the second pixel area. Therefore, the second light emitting area ratio of the second pixel PX2 may be greater than the first light emitting area ratio of the first pixel PX1.
[0154] Therefore, the area difference between the light emitting area of the organic light emitting layer OL of the first pixel PX1 and the light emitting area of the organic light emitting layer OL of the second pixel PX2 is reduced, and thus the brightness difference caused by the difference between the first pixel area and the second pixel area can be reduced. Therefore, the brightness of the first pixel PX1 and the second pixel PX2 becomes uniform.
[0155] Fig.13A and Fig. 13B 2 is a plan view showing a first pixel and a second pixel according to an exemplary embodiment of the present disclosure. Fig.13A and Fig. 13B , the third width and the fourth width may be different from each other. For example, the third width may be greater than the fourth width. In addition, the first width may be greater than the second width.
[0156] In more detail, the sum of the widths Lc1 to Lc4 of the first black matrix BM1 may be greater than the sum of the widths Lc5 to Lc8 of the second black matrix BM2. The width of the second black matrix BM2 in the tangential direction (ie, one of Lc1, Lc2, Lc3, and Lc4) may be greater than the width of the second black matrix BM2 disposed between the sub-pixels SPX1 to SPX3 adjacent to each other. The width on (i.e., one of Lc5, Lc6, Lc7 and Lc8).

In more detail, a first minimum distance dc1 which is the smallest between the first sub-light emitting area SEA1 and the center of the display panel 400 may be different from a second minimum distance dc2 which is the smallest between the second sub-light emitting area SEA2 and the center of the display panel 400. The first minimum distance dc1 may be greater than the second minimum distance dc2 and equal to a third minimum distance dc3 which is the smallest between the third sub-light emitting area SEA3 and the center of the display panel 400.

The first to sixth display lines Ld1 to Ld6 are substantially parallel to the radial direction. And arranged in the tangential direction The first to sixth display lines Ld1 to Ld6 are similar to each other, and thus the first and second display lines Ld1 and Ld2 will be described in detail as representative examples. The description of the first and second display lines Ld1 and Ld2 may be similarly applied to other display lines.
[0162] Reference Fig.16 The first display line Ld1 includes a gate line and a data line, and applies a gate signal and a data voltage to the first pixel PX1. The first pixel PX1 displays an image in response to the gate signal and the data voltage from the first display line Ld1.
[0163] The first display line Ld1 is arranged in the tangential direction In the present exemplary embodiment, the first display line Ld1 is disposed between two first pixels PX1 adjacent to each other in the radial direction. The pixel PX2 is spaced apart from the second pixel PX2 and is tangentially spaced apart from the second pixel PX2. In other words, the first display line Ld1 may not be disposed between the second pixel PX2 to the sixth pixel PX6. In the present exemplary embodiment, the first display line Ld1 may be disposed in the radial direction. Overlaps with the second pixel PX2.

[0165] The second display line Ld2 is arranged in the tangential direction Between two adjacent second pixels PX2 and arranged in the tangential direction In the present exemplary embodiment, the second display line Ld2 is disposed between two first pixels PX1 adjacent to each other in the radial direction. The pixel PX3 is spaced apart from the third pixel PX3 and is tangentially spaced apart from the third pixel PX3. In other words, the second display line Ld2 may not be disposed between the third pixel PX3 to the sixth pixel PX6. In this exemplary embodiment, the second display line Ld2 may be disposed between the third pixel PX3 to the sixth pixel PX6. Overlaps with the third pixel PX3.
[0166] In the above structure, in the tangential direction The width of the non-display area NDA2 between the second pixels PX2 adjacent to each other on the horizontal direction and the ... The width of the non-display area NDA3 between the third pixels PX3 adjacent to each other is reduced, and the areas of the second pixel area and the third pixel area are increased. Therefore, the pixel area difference between the first pixel PX1 to the third pixel PX3 is reduced, and the brightness of the first pixel PX1 to the third pixel PX3 becomes uniform.
[0167] Fig.17 is a plan view showing a display panel according to an exemplary embodiment of the present disclosure, and Fig.18 It is shown Fig.17 An enlarged view of the first display line and the second display line is shown.
[0168] exist Fig.17 In the embodiment, the display panel 400 has Fig. 7A The structure and function of the display panel 400 shown are similar to those of the display panel 400, and therefore different features of the additional display lines will be described in detail.

And in the tangential direction 1 to 6 gate lines GL1 to GL6 are similar to each other, the first gate line GL1 and the second gate line GL2 will be described in detail as a representative example. The description of the first gate line GL1 and the second gate line GL2 can be similarly applied to other gate lines. In addition, the first data line DL1 to the k-th data line DLk are similar to each other, and therefore the first data line DL1 will be described as a representative example. The description of the first data line DL1 can be similarly applied to other data lines.
[0171] Reference Fig.18 The first gate line GL1 transmits a first gate signal, and the first data line DL1 transmits a data voltage. The first pixel PX1_1 displays an image in response to the first gate signal provided through the first gate line GL1 and the data voltage provided through the first data line DL1.
[0172] The first data line DL1 is arranged in the tangential direction The first pixels PX1_1 and PX1_k are located between the two first pixels PX1_1 and PX1_k adjacent to each other on the tangential direction.

[0174] Fig.19is a cross-sectional view showing a display module according to an exemplary embodiment of the present disclosure, Fig. 20 It is shown Fig.19 A plan view of the display panel is shown, and Fig.21 It is shown Fig.19 A rear view of the display panel is shown.
[0175] Reference Fig.19 , the first display area DA1 includes a first portion DA11, a second portion DA12, and a bent portion DA13 connecting the first portion DA11 and the second portion DA12. The bent portion DA13 is bent so that the first portion DA11 is folded downward. For example, the first portion DA11 may be connected to the second portion DA12, and may be folded away from the second portion DA12 toward the housing 500 so that the first portion DA11 and the second portion DA12 face each other in the first direction DR1. In other words, the first portion DA11 is folded to allow the second portion DA12 to be inserted between the window member 300 and the first portion DA11.
[0176] Reference Fig.19 , Fig. 20 and Fig.21 , a display surface of the second portion DA12 faces the lower surface 301 of the window member 300. A display surface of the first portion DA11 faces the upper surface of the housing 500. In other words, a lower surface of the first portion DA11 may be opposite to a lower surface of the window member 300.
[0177] In the present exemplary embodiment, the display module 200 may further include a flexible printed circuit board 201 and a display printed circuit board 205. The flexible printed circuit board 201 connects the display panel 400 and the display printed circuit board 205. One end of the flexible printed circuit board 201 is connected to an edge of the first portion DA11, and the other end of the flexible printed circuit board 201 is connected to the display printed circuit board 205. A connection pad is provided at an edge of the first portion DA11. The connection pad connects the wires of the display panel 400 to the flexible printed circuit board 201.
[0178] The second portion DA12 is disposed between the flexible printed circuit board 201 and the window member 300 , and between the display printed circuit board 205 and the window member 300 .
[0179] Since the flexible printed circuit board 201 is connected to the display panel 400 through the pad portion provided on the first portion DA11, a black matrix for preventing the pad portion from being perceived is not required. Therefore, the frame width of the display panel 400 can be effectively reduced.
[0180] Fig. 22 is a cross-sectional view showing a display module according to an exemplary embodiment of the present disclosure.
[0181] exist Fig. 22 In the embodiment, the display module 200 has Figure 3 The structure and function of the display module 200 shown are similar to the structure and function, and therefore the different features of the additional touch module 800 will be described in detail. Fig. 22 , the display module 200 includes a touch module 800 .
[0182] In detail, the touch module 800 is disposed between the window member 300 and the display panel 400. In the present exemplary embodiment, the touch module 800 includes a first touch area TA1 and a second touch area TA2 that are distinguished from each other in a horizontal direction. The first touch area TA1 and the second touch area TA2 are respectively disposed under the first window area WA1 and the second window area WA2. The first touch area TA1 senses a first external input applied to the first window area WA1 to generate a touch signal, and the second touch area TA2 senses a second external input applied to the second window area WA2 to generate a touch signal.
[0183] As described above, the second thickness of the second window area WA2 is greater than the first thickness of the first window area WA1. Therefore, the strength of the second external input applied to the second touch area TA2 after passing through the second window area WA2 may be less than the strength of the first external input applied to the first touch area TA1 after passing through the first window area WA1.
[0184] In the present exemplary embodiment, the sensitivity of the second touch area TA2 may be higher than the sensitivity of the first touch area TA1. Therefore, the touch module 800 may compensate for the difference in intensity between the first external input and the second external input, and thus the touch module 800 may accurately sense the external input. In order to increase the sensitivity of the second touch area TA2 to be higher than the sensitivity of the first touch area TA1, the size of the touch electrode, the number of touch electrodes per unit area, the distance between the touch electrodes, the processing of the touch signal and the sensing signal may be controlled.
[0185] Fig.23A It is shown Fig. 22 An enlarged cross-sectional view of the touch module is shown, and FIG. 23B to FIG. 23D is a plan view showing a touch module according to an exemplary embodiment of the present disclosure.
[0186] Reference Fig.23A , the touch module 800 includes a base layer 810 and touch electrodes disposed on the base layer 810. In the present exemplary embodiment, the touch electrodes include a first touch electrode TE1 disposed in a first touch area TA1, and a second touch electrode TE2 disposed in a second touch area TA2.
[0187] The touch module 800 may be, for example, a self-capacitive type or a mutual-capacitive type. The first touch electrodes TE1 and the second touch electrodes TE2 may be deformed, arranged, and connected corresponding to the type of the touch module 800 .
[0188] In the present exemplary embodiment, the size of the first touch electrode TE1 may be greater than the size of the second touch electrode TE2. A third length L3 of the first touch electrode TE1 in the horizontal direction may be greater than a fourth length L4 of the second touch electrode TE2 in the horizontal direction.
[0189] Reference Fig. 23B , the first electrode area of the first touch electrode TE1 may be greater than the second electrode area of the second touch electrode TE2, and the distance between two first touch electrodes TE1 adjacent to each other may be substantially equal to the distance between two second touch electrodes TE2 adjacent to each other. In the present exemplary embodiment, each of the first touch electrode TE1 and the second touch electrode TE2 may have a substantially square shape.
[0190] In the present exemplary embodiment, the number of second touch electrodes TE2 per unit area may be greater than the number of first touch electrodes TE1 per unit area. Therefore, the intensity difference between the first external input and the second external input may be compensated, and thus the touch module 800 may accurately sense the external input.
[0191] See also Fig.23C , the third distance P3 in the horizontal direction between the two first touch electrodes TE1 adjacent to each other may be greater than the fourth distance P4 in the horizontal direction between the two second touch electrodes TE2 adjacent to each other, and the first electrode area of the first touch electrode TE1 and the second electrode area of the second touch electrode TE2 may be equal to each other, but they should not be limited thereto or thereby. That is, the third distance P3 and the fourth distance P4 may be equal to each other. Therefore, the intensity of the fringe field formed between the second touch electrodes TE2 adjacent to each other may be greater than the intensity of the fringe field formed between the first touch electrodes TE1 adjacent to each other. Therefore, the intensity difference between the first external input and the second external input can be compensated, and thus the accuracy of the touch module 800 regarding the external input can be improved.
[0192] See also Fig.23D , the first sensing signal DS1 is applied to the first touch area TA1. The first sensing signal DS1 may be a signal provided to the first touch electrode TE1 to sense a first external input. Similarly, the second sensing signal DS2 is applied to the second touch area TA2. The second sensing signal DS2 may be a signal provided to the second touch electrode TE2 to sense a second external input.
[0193] In this exemplary embodiment, the touch module 800 may further include a sensing controller 830. The sensing controller 830 is disposed on the base layer 810, the display printed circuit board 205 (see Fig.19 ) or electronic module substrate 110 (see Fig.19 ). The sensing controller 830 includes a first sub-sensing controller 831 and a second sub-sensing controller 832. The first sub-sensing controller 831 and the second sub-sensing controller 832 generate a first sensing signal DS1 and a second sensing signal DS2, respectively, and receive a first touch signal TS1 and a second touch signal TS2, respectively.
[0194] The first touch electrode TE1 of the first touch area TA1 outputs a first touch signal TS1 in response to the first sensing signal DS1, and the second touch electrode TE2 of the second touch area TA2 outputs a second touch signal TS2 in response to the second sensing signal DS2. The sensing controller 830 calculates coordinates of an external input using the first and second touch signals TS1 and TS2.
[0195] The first sub-sensing controller 831 and the second sub-sensing controller 832 may generate the first sensing signal DS1 and / or the second sensing signal DS2 to have different strengths so that the strength difference between the first external input and the second external input is compensated. For example, since the strength of the first external input is greater than the strength of the second external input, the first sub-sensing controller 831 and the second sub-sensing controller 832 may increase the strength of the second sensing signal DS2. Therefore, the strength difference between the first external input and the second external input may be compensated, and thus the accuracy of the touch module 800 with respect to the external input may be improved.
[0196] The present disclosure should not be limited to this or thereby. In the present exemplary embodiment, the intensity of the first sensing signal DS1 and the intensity of the second sensing signal DS2 may be the same as each other, and the first sub-sensing controller 831 and the second sub-sensing controller 832 may process the first touch signal TS1 and the second touch signal TS2 based on the intensity difference between the first external input and the second external input. Therefore, the intensity difference between the first external input and the second external input may be compensated.

In more detail, the conductive portions CP each having a width in the range of several hundred nanometers to several hundred micrometers may cross each other to form a mesh shape. An opening OP may be defined between the conductive portions CP. The transmittance and resistance of the first sensor pattern TSP1 and the second sensor pattern TSP2 may be determined according to the size of the opening or the width of the conductive portion CP.

[0206] Reference Fig.25A , the touch module 800 includes a first touch area TA1, a second touch area TA2, and a third touch area TA3. The touch module 800 has an elliptical shape, for example, a substantially circular shape. The first to third touch areas TA1 to TA3 are defined to correspond to the shape of the touch module 800.
[0207] In more detail, the first touch area TA1 to the third touch area TA3 are arranged in the radial direction. The first touch area TA1 to the third touch area TA3 are sequentially arranged. The boundaries of the first touch area TA1 to the third touch area TA3 have an elliptical shape or a substantially circular shape. When viewed in a plan view, each of the first touch area TA1 and the second touch area TA2 has a ring shape, and the third touch area TA3 has a circular shape. The circumferences of the first touch area TA1 to the third touch area TA3 become smaller in the order of the first touch area TA1, the second touch area TA2, and the third touch area TA3.
[0208] Fig.25B is a plan view showing a touch module according to an exemplary embodiment of the present disclosure.
[0209] For the convenience of explanation, Fig.25B Some components of the touch module are omitted. Fig.25B The touch module 800 may further include touch wires. The touch wires may include, for example, first, second, and third touch wires Lt1, Lt2, and Lt3 connected to the first, second, and third touch electrodes TE1, TE2, and TE3, respectively.
[0210] In the present exemplary embodiment, each of the first to third touch electrodes TE1 to TE3 includes a A pair of sides and substantially parallel to the tangential direction A pair of sides.
[0211] The first to third touch lines Lt1 to Lt3 are substantially parallel to the radial direction. And in the tangential direction The first to third touch lines Lt1 to Lt3 are similar to each other, and thus the first touch line Lt1 and the second touch line Lt2 will be described as representative examples. The description of the first touch line Lt1 and the second touch line Lt2 may be similarly applied to the third touch line Lt3.
[0212] In the present exemplary embodiment, the first touch line Lt1 applies a sensing signal to the first touch electrode TE1 and receives a touch signal from the first touch electrode TE1. In response to the sensing signal from the first touch line Lt1, the first touch electrode TE1 outputs a touch signal corresponding to the self capacitance changed by the external input.
[0213] The first touch line Lt1 is arranged in the tangential direction In the present exemplary embodiment, the first touch line Lt1 is disposed between two first touch electrodes TE1 adjacent to each other in the radial direction. In the tangential direction, the second touch electrode TE2 is spaced apart from the second touch electrode TE2. In other words, the first touch line Lt1 may not be disposed between the second touch electrode TE2 and the third touch electrode TE3.
[0214] In the present exemplary embodiment, the second touch line Lt2 applies a sensing signal to the second touch electrode TE2 and receives a touch signal from the second touch electrode TE2. In response to the sensing signal from the second touch line Lt2, the second touch electrode TE2 outputs a touch signal corresponding to the self capacitance changed by the external input.
[0215] The second touch line Lt2 is arranged in the tangential direction In the present exemplary embodiment, the second touch line Lt2 is disposed between two second touch electrodes TE2 adjacent to each other in the radial direction. In the tangential direction, the third touch electrode TE3 is spaced apart from the third touch electrode TE3. In other words, the second touch wire Lt2 may not be disposed between the second touch electrode TE2 and the third touch electrode TE3. In the present exemplary embodiment, the first touch wire Lt1 is disposed in the radial direction. The electrode TE2 overlaps with the second touch electrode TE2.
[0216] In the above structure, in the tangential direction The width of the non-touch area NTA2 between two second touch electrodes TE2 adjacent to each other in the vertical direction can be reduced. Therefore, the resolution and sensitivity of the touch module 800 can be improved. Similarly, the width of the non-touch area NTA2 between two second touch electrodes TE2 adjacent to each other in the vertical direction can be reduced. The width of the non-touch area NTA3 between two third touch electrodes TE3 adjacent to each other is reduced. Therefore, the sensitivity of the touch module 800 can be improved.

The crown sensor 620 senses the rotation or movement of the crown shaft 631 in the horizontal direction, or senses the position of the crown shaft 631 to output a crown signal. As an example, the electronic module substrate 110 uses the crown signal to control the display module 200. The user rotates the crown 630 or moves the crown 630 in the horizontal direction to control the display module 200.

Accordingly, the display quality of the display module 200 can be improved. In addition, the first radius of curvature r1, the second radius of curvature r2, and the third radius of curvature r3 may satisfy the following relationship: r1 > r2 > r3.

For example, when the jth side length Lj is 1 and the (j+1)th side length Lj+1 is 0.8, (M, N) satisfying the equation may be (8, 10) or (12, 15). Since the jth pixel PXj and the (j+1)th pixel PXj+1 satisfy the equation, the relative boundary BL of the jth display area DAj and the (j+1)th display area DAj+1 may be substantially parallel to the second direction DR2.
