[0088] The microphone processes external acoustic signals into electrical voice data. The processed voice data can be utilized in various ways depending on the function (or application running) being performed on the display device (1). Meanwhile, various noise removal algorithms can be implemented in the microphone to remove noise generated during the process of receiving external acoustic signals.

The input device may include mechanical input means or touch input means, such as a button, dome switch, jog wheel, jog switch, etc., located on the rear or side of the display device (1). The touch input means may be formed by a touchscreen layer of the display panel (10).

[0090] The sensor unit may include one or more sensors that sense at least one of information within the display device (1), surrounding environment information surrounding the display device (1), and user information, and generate a corresponding sensing signal. Based on this sensing signal, the main processor may control the operation or function of the display device (1), or perform data processing, functions, or operations related to an application installed on the display device (1). The sensor unit may include at least one of a proximity sensor, an illumination sensor, an acceleration sensor, a magnetic sensor, a gravity sensor (G-sensor), a gyroscope sensor, a motion sensor, an RGB sensor, an infrared sensor (IR sensor: infrared sensor), a fingerprint sensor, an ultrasonic sensor, an optical sensor, a battery gauge, an environmental sensor (e.g., a barometer, a hygrometer, a thermometer, a radiation detection sensor, a heat detection sensor, a gas detection sensor, etc.), and a chemical sensor (e.g., an electronic nose, a healthcare sensor, a biometric sensor, etc.).

[0091] A proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object existing nearby using the force of an electromagnetic field or infrared rays without mechanical contact. Examples of proximity sensors include transmissive photoelectric sensors, direct reflection photoelectric sensors, mirror reflection photoelectric sensors, high-frequency oscillating proximity sensors, capacitive proximity sensors, magnetic proximity sensors, and infrared proximity sensors.

[0092] An ultrasonic sensor can recognize the location information of an object using ultrasound. The main processor described above is capable of calculating the location of an object through information detected by an optical sensor and a plurality of ultrasonic sensors. Since the speed of light and the speed of ultrasound are different, the location of an object can be calculated by utilizing the time it takes for light to reach the optical sensor and the time it takes for ultrasound to reach the ultrasonic sensor.

[0095] A haptic module generates various tactile effects that a user can perceive. The haptic module can provide vibration to the user as a tactile effect. The intensity and pattern of vibrations generated by the haptic module can be controlled by the user's selection or by the settings of the main processor. For example, the haptic module may synthesize and output different vibrations or output them sequentially. In addition to vibration, the haptic module can generate various tactile effects, such as effects caused by stimuli like a pin array moving perpendicularly to the contacted skin surface, air jet or suction force through a nozzle or inlet, brushing against the skin surface, contact with an electrode, and electrostatic force, as well as effects caused by the reproduction of hot and cold sensations using elements capable of endothermic or exothermic reactions. The haptic module can not only transmit tactile effects through direct contact but can also be implemented so that the user can feel tactile effects through muscle sensations such as fingers or arms.

In one embodiment, one end of the terminal portion (80-2b) may be exposed to the outside of the gasket body portion (80-1) depending on the volume change (or height change) of the gasket body portion (80-1). For example, a hole (80-1a) may be formed in the gasket body portion (80-1) into which the terminal portion (80-2b) is inserted. In another embodiment, although not shown in the drawings, it is also possible for the terminal portion (80-2b) to have a form that is completely inserted inside the gasket body portion (80-1).

At this time, the arrangement of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) is not limited to the above and can be arranged in various ways. However, for the convenience of explanation, the following description will focus on the fact that one of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) is positioned at the center of the gasket body section (80-1), and the remaining of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) are positioned on the same arbitrary circumference centered on one of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be).

[0112] The first terminal section (80-2ba) may be positioned at the center of the gasket body section (80-1). Additionally, the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may be arranged radially around the first terminal section (80-2ba). At this time, the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may each be spaced apart from the first terminal section (80-2ba) by the same distance.

[0113] The length of one of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may differ from the length of the other of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be). For example, the length of one of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may be greater or smaller than the length of the other of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be). In another embodiment, the lengths of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may differ from each other. For the sake of convenience of explanation, the following description will focus on cases where the lengths of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) are different from each other.

[0114] In one embodiment, based on FIG. 4a, the length of the second terminal section (80-2bb) may be smaller than the lengths of the first terminal section (80-2ba), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be), respectively. Additionally, the lengths of the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may increase sequentially with respect to each other. The length of the first terminal section (80-2ba) may be greater than the length of the second terminal section (80-2bb) and smaller than the length of the third terminal section (80-2bc). At this time, the lengths of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may vary, although they are not limited to the above.

[0115] Each of the first terminal section (80-2ba), second terminal section (80-2bb), third terminal section (80-2bc), fourth terminal section (80-2bd), and fifth terminal section (80-2be), having the lengths described above, may be arranged in a form inserted inside the gasket body section (80-1). At this time, each of the first terminal section (80-2ba), second terminal section (80-2bb), third terminal section (80-2bc), fourth terminal section (80-2bd), and fifth terminal section (80-2be) may be less than the height of the gasket body section (80-1). In this case, the ends of the first terminal section (80-2ba), the second terminal section (80-2bb), the third terminal section (80-2bc), the fourth terminal section (80-2bd), and the fifth terminal section (80-2be) may be spaced apart from the bottom surface of the gasket body section (80-1).

[0116] The terminal portion (80-2b) described above can generate a signal by contacting a detection portion of a display circuit board located at a distance from the bottom surface of the gasket body portion (80-1) or at the bottom of the gasket body portion (80-1), or through a gap with the detection portion.

[0117] Figure 5 is a rear view schematically showing the location of the display circuit board and gasket illustrated in Figure 3.

[0118] Referring to FIG. 5, one side of the display circuit board (51) may be bent. At this time, the display circuit board (51) may include a first side and a second side. The first side may be a side facing the display panel (10) with reference to FIG. 3, and the second side may be a side facing the bracket (60) with reference to FIG. 3.

[0119] In the above case, the display circuit board (51) can be connected to the main circuit board (not shown) through a connector (CNA). At this time, the connector (CNA) may include a flexible printed circuit. At this time, one end of the connector (CNA) may be attached to the display circuit board (51), and the other end of the connector (CNA) may be connected to the main circuit board (70, see FIG. 2).

[0120] A display circuit board (51) may be placed on the rear of a display panel (10). At this time, the display circuit board (51) may include a detection area (55). Multiple detection areas (55) may be provided. For example, the detection areas (55) may correspond to each gasket (80).

[0121] Each detection area (55) can detect deformation of each gasket (80) that is positioned to correspond to each gasket (80). At this time, each detection area (55) can detect a signal generated according to the deformation of each gasket (80).

[0122] The location and number of the detection area (55) as described above can be determined according to the location and number of gaskets (80) as described above. However, for the convenience of explanation, the following description will focus on the case where six gaskets (80) are arranged.

[0123] A plurality of detection areas (55) may include a first detection area (55-1), a second detection area (55-2), a third detection area (55-3), a fourth detection area (55-4), a fifth detection unit, and a sixth detection area (55-6) that are spaced apart from each other. In this case, the first detection area (55-1), the second detection area (55-2), the fifth detection area (55-5), and the sixth detection area (55-6) may each be placed at the corner portions of the display circuit board (51). Additionally, the third detection area (55-3) and the fourth detection area (55-4) may be placed at the central portion of the display circuit board (51) and may be placed on both sides of the connector (CNA) with the connector (CNA) at the center. The first detection area (55-1) and the second detection area (55-2) can also be placed on both sides of the connector (CNA) with the connector (CNA) as the center, and the fifth detection area (55-5) and the sixth detection area (55-6) can also be placed on both sides of the connector (CNA) with the connector (CNA) as the center.

[0124] FIG. 6a is a circuit diagram schematically showing the gasket and the sensing part illustrated in FIG. 3. FIG. 6b is a cross-sectional view taken along the line AA´ illustrated in FIG. 6a. FIG. 6a is a circuit diagram briefly showing the positions of the sensing part and the gasket illustrated in FIG. 5. FIG. 6b is also a cross-sectional view showing the 1-1 wiring, 2-1 wiring, and 1 gasket illustrated in FIG. 6a.

[0125] Referring to FIG. 6, a gasket (80) may be placed on the sensing unit (56). For example, a plurality of gaskets (80) may be placed on the sensing unit (56). At this time, the plurality of gaskets (80) may be placed spaced apart from each other. For example, the plurality of gaskets (80) may be placed on the first gasket (81), second gasket (82), third gasket (83), fourth gasket (84), fifth gasket (85), and sixth gasket (86) which are placed spaced apart from each other. At this time, the number of gaskets (80) is not limited to the above and may be at least two. In such a case, each gasket (80) may be placed in each sensing area shown in FIG. 5.

[0126] The sensing unit (56) may include a first wiring (56a) and a second wiring (56b) that intersect each other when viewed in a planar view on one side of the display circuit board (51). At this time, the first wiring (56a) and the second wiring (56b) may be electrically insulated from each other. The first wiring (56a) and the second wiring (56b) may each be arranged to overlap at least once with each sensing area (not shown) illustrated in FIG. 5. The first wiring (56a) and the second wiring (56b) may each be provided in multiple numbers to form multiple points where they intersect each other. At this time, the multiple first wirings (56a) may be arranged parallel to each other and may be spaced apart from each other at a certain distance. Additionally, the multiple second wirings (56b) may be arranged parallel to each other and may be spaced apart from each other at a certain distance. In this case, when viewed in a planar view, each first wiring (56a) and each second wiring (56b) may intersect each other at one point. In one embodiment, the first wiring (56a) and the second wiring (56b) may be placed on different layers. For example, one of the first wiring (56a) or the second wiring (56b) may be placed on one of the outer surfaces of the display circuit board (51), and the other of the first wiring (56a) or the second wiring (56b) may be placed on the inside of the display circuit board (51) or on the other of the outer surfaces of the display circuit board (51). At this time, when viewed on a plane, a part of the display circuit board (51) is placed between the first wiring (56a) and the second wiring (56b) at the point where the first wiring (56a) and the second wiring (56b) intersect each other, thereby electrically insulating the first wiring (56a) and the second wiring (56b). In another embodiment, the first wiring (56a) and the second wiring (56b) may be placed on the same layer or at different heights. For example, the first wiring (56a) and the second wiring (56b) may be placed inside the display circuit board (51) so as to be spaced apart from each other in the height direction of the display circuit board (51).At this time, a part of the display circuit board (51) may be placed between the first wiring (56a) and the second wiring (56b) so that they can be electrically insulated from each other. As another embodiment, it is also possible for the first wiring (56a) and the second wiring (56b) to be placed on the same layer and at the same height. For example, the first wiring (56a) and the second wiring (56b) may be placed on the same outer surface of the display circuit board (51) or at the same height inside the display circuit board (51). At this time, it is also possible to place a separate insulating material between the first wiring (56a) and the second wiring (56b) that intersect each other when viewed on a plane so that the first wiring (56a) and the second wiring (56b) are insulated from each other. Additionally, in this case, when viewed in a planar view, at the point where the first wiring (56a) and the second wiring (56b) intersect, one of the first wiring (56a) and the second wiring (56b) may be arranged to extend to the upper or lower part of the other of the first wiring (56a) and the second wiring (56b). That is, at the point where the first wiring (56a) and the second wiring (56b) intersect when viewed in a planar view, one of the first wiring (56a) or the second wiring (56b) may include a bridge that extends from one of the first wiring (56a) or the second wiring (56b), is connected at a different height from one of the first wiring (56a) or the second wiring (56b), and then is connected again to the first wiring (56a) or the second wiring (56b).

[0127] One of the first wiring (56a) and the second wiring (56b) as described above may be placed at a different height from the other of the first wiring (56a) and the second wiring (56b). For convenience of explanation, the following description will focus on the case where the first wiring (56a) is placed on the outer surface of the display circuit board (51), the second wiring (56b) is placed inside the display circuit board (51), and a part of the display circuit board (51) is placed between the first wiring (56a) and the second wiring (56b).

[0128] In one embodiment, at least one of the first wiring (56a) and the second wiring (56b) as described above may have a uniform width in the longitudinal direction. In another embodiment, although not illustrated in the drawings, at least one of the first wiring (56a) and the second wiring (56b) may have different widths at the point where they intersect each other when viewed in a plane. For example, at least one of the first wiring (56a) and the second wiring (56b) may include an electrode formed in a rhombus shape at the point where they intersect each other, with an area larger than that of other parts.

[0129] The sensing unit (56) can detect a signal based on the deformation of the gasket (80) placed in the sensing area. For example, as in one embodiment, the sensing unit (56) can detect the deformation of the gasket (80) based on a change in the distance between at least one of the contact parts of the gasket (80) and the sensing unit (56). Specifically, when the distance between at least one of the contact parts of the gasket (80) and one of the first wiring (56a) or the second wiring (56b) varies, the capacitor between the first wiring (56a) and the second wiring (56b) changes, and the deformation of the gasket (80) can be determined by the touch driving unit (53) calculating this change.

[0130] In another embodiment, the sensing unit (56) can detect deformation of the gasket (80) when at least one of the contact parts of the gasket (80) comes into contact. At this time, the touch driving unit (53) can determine whether the gasket (80) is deformed by detecting a change in the capacitor between the first wiring (56a) and the second wiring (56b) at the point where the first wiring (56a) and the second wiring (56b) intersect each other, as described above.

[0131] In another embodiment, the sensing part (56) may also detect a signal based on the change in distance and contact between at least one of the contact parts of the gasket (80) and the sensing part (56).

[0132] For convenience of explanation, the sensing unit (56) will be described in detail below, focusing on cases where the distance between at least one of the contact parts of the sensing unit (56) and the gasket (80) varies, and where at least one of the contact parts of the gasket (80) contacts the sensing unit (56) to detect whether the gasket (80) is deformed.

[0133] The first wiring (56a) as described above can be determined according to the number of gaskets (80).

In this case, the first wiring (56a) may be extended in a straight line. As another embodiment, the first wiring (56a) may not be in a straight line, and some parts may be in a straight line, while others may be in a bent shape or others may be in a rounded shape.

The sixth gasket (86) may include a first-6 terminal section (86-2ba), a second-6 terminal section (86-2bb), a third-6 terminal section (86-2bc), a fourth-6 terminal section (86-2bd), and a fifth-6 terminal section (86-2be).

At this time, at least one of the 2-1 terminal section (81-2bb), 3-1 terminal section (81-2bc), 2-2 terminal section (82-2bb), 3-2 terminal section (82-2bc), 2-3 terminal section (83-2bb), and 3-3 terminal section (83-2bc) can come into contact with the 1-1 wiring (56a-1) by varying the shape of the 1 gasket body section (not shown) of the 1 gasket (81) according to the position and magnitude of the force applied to the bracket (60). The 1-2 wiring (56a-2) can be arranged to overlap with the 1-1 terminal section (81-2ba), the 1-2 terminal section (82-2ba), and the 1-3 terminal section (83-2ba).

At this time, at least one of the 4-1 terminal part (81-2bd), 5-1 terminal part (81-2be), 4-2 terminal part (82-2bd), 5-2 terminal part (82-2be), 4-3 terminal part (83-2bd), and 5-3 terminal part (83-2be) may come into contact with the 1-3 wiring (56a-3) depending on the position and magnitude of the force applied to the bracket (60).

[0137] Additionally, the 1-4 wiring (56a-4), 1-5 wiring (56a-5), and 1-6 wiring (56a-6) may be placed below the 4th gasket (84), 5th gasket (85), and 6th gasket (86). In this case, the 1-4 wiring (56a-4) may be placed to overlap with the 2-4 terminal section (84-2bb), 3-4 terminal section (84-2bc), 2-5 terminal section (85-2bb), 3-5 terminal section (85-2bc), 2-6 terminal section (86-2bb), and 3-6 terminal section (86-2bc). The 1-5 wiring (56a-5) may be arranged to overlap with the 1-4 terminal section (84-2ba), the 1-5 terminal section (85-2ba), and the 1-6 terminal section (86-2ba). Additionally, the 1-6 wiring (56a-6) may be arranged to overlap with the 4-4 terminal section (84-2bd), the 5-4 terminal section (84-2be), the 4-5 terminal section (85-2bd), the 5-5 terminal section (85-2be), the 4-6 terminal section (86-2bd), and the 5-6 terminal section (86-2be).

[0138] In the above case, the second wiring (56b) may include, from the left side with reference to FIG. 6, the second-1 wiring (56b-1), second-2 wiring (56b-2), second-3 wiring (56b-3), second-4 wiring (56b-4), second-5 wiring (56b-5), second-6 wiring (56b-6), second-7 wiring (56b-7), second-8 wiring (56b-8) and second-9 wiring (56b-9). In this case, when viewed on a plane, the second-1 wiring (56b-1) may overlap with the third-1 terminal section (81-2bc), the fourth-1 terminal section (81-2bd), the third-5 terminal section (85-2bc) and the fourth-5 terminal section (85-2bd). When viewed in a planar view, the 2-2 wiring (56b-2) may overlap with the 1-1 terminal section (81-2ba) and the 1-5 terminal section (85-2ba). Additionally, when viewed in a planar view, the 2-3 wiring (56b-3) may be arranged to overlap with the 2-1 terminal section (81-2bb), the 5-1 terminal section (81-2be), the 2-5 terminal section (85-2bb), and the 5-5 terminal section (85-2be). When viewed in a planar view, the 2-4 wiring (56b-4) may overlap with the 3-3 terminal section (83-2bc), the 4-3 terminal section (83-2bd), the 3-4 terminal section (84-2bc), and the 4-4 terminal section (84-2bd). When viewed in a planar view, the 2-5 wiring (56b-5) may overlap with the 1-3 terminal section (83-2ba) and the 1-4 terminal section (84-2ba). Additionally, when viewed in a planar view, the 2-6 wiring (56b-6) may be arranged to overlap with the 2-3 terminal section (83-2bb), the 5-3 terminal section (83-2be), the 2-4 terminal section (84-2bb), and the 5-4 terminal section (84-2be). When viewed in a planar view, the 2-7 wiring (56b-7) may be arranged to overlap with the 3-2 terminal section (82-2bc), the 4-2 terminal section (82-2bd), the 3-6 terminal section (86-2bc), and the 4-6 terminal section (86-2bd). When viewed in a planar view, the 2-8 wiring (56b-8) can be arranged to overlap with the 1-2 terminal section (82-2ba) and the 1-6 terminal section (86-2ba).When viewed in a planar view, the 2-9 wiring (56b-9) can be arranged to overlap with the 2-2 terminal section (82-2bb), the 5-2 terminal section (82-2be), the 2-6 terminal section (86-2bb), and the 5-6 terminal section (86-2be).

[0139] In the above case, the first wiring (56a) and the second wiring (56b) may intersect at multiple points when viewed on a plane. The points where the first wiring (56a) and the second wiring (56b) intersect each other may be located at the lower part of each terminal section of each gasket (80). That is, based on FIG. 6, the points where the first wiring (56a) and the second wiring (56b) intersect may be located at the lower part of each of the first-1 terminal section (81-2ba) to the fifth-1 terminal section (81-2be). Additionally, a point where the first wiring (56a) and the second wiring (56b) intersect may be arranged at the lower portions of each of the first-2 terminal section (82-2ba) to the fifth-2 terminal section (82-2be), the lower portions of each of the first-3 terminal section (83-2ba) to the fifth-3 terminal section (83-2be), the lower portions of each of the first-4 terminal section (84-2ba) to the fifth-4 terminal section (84-2be), the lower portions of each of the first-5 terminal section (85-2ba) to the fifth-5 terminal section (85-2be), and the lower portions of each of the first-6 terminal section (86-2ba) to the fifth-6 terminal section (86-2be).

[0140] In the above case, the first wiring (56a) and the second wiring (56b) can be connected to a touch driving unit (53, see FIG. 5). In this case, the touch driving unit (53) can detect a change in the capacitor between the first wiring (56a) and the second wiring (56b), which are arranged to intersect each other at the bottom of each terminal, when each terminal comes close to or contacts the second wiring (56b) at the point where the first wiring (56a) and the second wiring (56b) intersect each other. Through this, the touch driving unit (53) can detect a terminal that has come into contact with or has changed distance from the point where the first wiring (56a) and the second wiring (56b) intersect among the plurality of terminals through this change in capacitor.

[0141] Referring to FIG. 3 and FIG. 6a, in the above case, the bracket (60) can be combined with the cover member (50) by applying pressure from the bottom of the display panel (10). At this time, the force can be applied while in contact with the entire outer surface of the bracket (60) (for example, the surface where the main circuit board is placed) or while in contact with each part of a plurality of parts of the outer surface of the bracket (60).

[0142] In the above case, if the force applied to the outer surface of the bracket (60) is not uniform, or if the force applied by the bracket (60) to each gasket (80) due to the force applied to the outer surface of the bracket (60) is not uniform across all gaskets (80), a problem may occur in which at least a part of the display panel (10) or the cover member (50) is damaged. In particular, in the above case, the corners of the display panel (10) or the corners of the cover member (50) may be damaged.

[0143] As described above, when force is applied to the bracket (60), the touch driving unit (53) detects a signal generated by the change in the shape of at least one of the plurality of gaskets (80), thereby detecting and determining the distribution of force applied to the bracket (60), the strength of the force, etc. For example, when a signal is generated from one of the plurality of gaskets (80) (e.g., one of the first gasket (81) to the sixth gasket (86)), it can be determined that the strength of the force applied to the gasket (80) where the signal is generated is greater than that of the other gasket (80) (e.g., another of the first gasket (81) to the sixth gasket (86)), or that the balance of force applied to the gasket (80) where the signal is generated is distorted. In such cases, the distribution of force applied to the bracket (60) can be adjusted, or the area of ​​force applied to the bracket (60) can be moved. As another embodiment, it is also possible to perform the above operation by calculating the number of terminal portions of each gasket (80) that have come into contact with the first wiring (56a) or have a different distance (d) between the first wiring (56a) from the beginning. Specifically, if the number of terminal portions that have come into contact with the first wiring (56a) or have a different distance (d) among one of the terminal portions of the plurality of gaskets (80) is different from the number of terminal portions that have come into contact with the first wiring (56a) or have a different distance (d) among another of the terminal portions of the plurality of gaskets (80), the position and magnitude of the force applied to the bracket (60) can be adjusted so that the two become equal.For example, if the number of terminal portions of the first gasket (81) that are in contact with the first wiring (56a) or whose distance (d) from the first wiring (56a) is variable is greater than the number of terminal portions of the second gasket (82) that are in contact with the first wiring (56a) or whose distance (d) from the first wiring (56a) is variable, it is determined that a greater force is applied to the first gasket (81) portion than to the second gasket (82) portion, and the magnitude of the force applied to the bracket (60) portion where the first gasket (81) is placed can be reduced, or the magnitude of the force applied to the bracket (60) portion where the second gasket (82) is placed can be increased. Alternatively, it is also possible to adjust the magnitude of the force applied to other parts of the bracket (60). On the other hand, if the number of terminal portions of the first gasket (81) that contacts the first wiring (56a) or whose distance (d) from the first wiring (56a) is variable is smaller than the number of terminal portions of the second gasket (82) that contacts the first wiring (56a) or whose distance (d) from the first wiring (56a) is variable, it is determined that a smaller force is applied to the first gasket (81) portion than to the second gasket (82) portion, and the magnitude of the force applied to the bracket (60) portion where the first gasket (81) is placed can be increased, or the magnitude of the force applied to the bracket (60) portion where the second gasket (82) is placed can be decreased. The above method is not limited to the above and may include all methods for determining the magnitude of the force, the location of the force, and the distribution of the force applied to the bracket (60) based on the number and location of terminal portions of each gasket that contact each wiring.

[0144] In the above case, the magnitude of the force applied to the bracket (60) can be adjusted so that the terminal portion of each gasket (80) contacts the first wiring (56a) or the number of terminal portions with varying distance (d) from the first wiring (56a) is maintained at a preset number. For example, when applying force to the bracket (60), the magnitude of the force applied to the bracket (60) can be controlled so that the terminal portion of each gasket (80) contacts the first wiring (56a) at a preset number. At this time, it is also possible to adjust the magnitude of the force, the position of the force, etc., in the same or similar manner as the method described above.

[0145] Therefore, the lifespan of the display device can be increased as damage to the display device does not occur when the bracket (60) is attached. In addition, the display device can display a clear image.

[0146] The display device supports the bracket (60) through a terminal portion placed in the gasket (80), thereby preventing the bracket (60) from moving toward the display panel even when an external force is applied to the bracket (60).

[0147] Meanwhile, the above process can be carried out similarly when a lower cover (90) is placed on a bracket (60), in addition to when a bracket (60) is attached to a display panel (10).

[0148] FIG. 7 is a plan view schematically showing the display panel illustrated in FIG. 1. FIG. 8 is a cross-sectional view schematically showing the display panel illustrated in FIG. 4. FIG. 8 is a cross-sectional view schematically showing a pixel taken along the BB´ line of FIG. 7.

[0149] Referring to FIGS. 7 and 8, the display device (1) may include a display panel (10), a display circuit board (51), a display driver (52), and a touch sensor driver (53). The display panel (10) may be a light-emitting display panel including a light-emitting element. For example, the display panel (10) may be an organic light-emitting display panel using an organic light-emitting diode including an organic light-emitting layer, a micro light-emitting diode display panel using a micro LED, a quantum dot light-emitting display panel using a quantum dot light-emitting diode including a quantum dot light-emitting layer, or an inorganic light-emitting display panel using an inorganic display element including an inorganic semiconductor.

[0150] The display panel (10) may be a transparent display panel that is implemented transparently so that an object or background placed on the lower surface of the display panel (10) can be seen on the upper surface of the display panel (10). Alternatively, the display panel (10) may be a reflective display panel that can reflect an object or background on the upper surface of the display panel (10).

[0151] The display panel (10) described above may include a display area (DA) that implements an image and a surrounding area (PA) arranged to surround the display area (DA). A separate driving circuit, pad, etc. may be arranged in this surrounding area (PA).

[0152] In one embodiment, the peripheral area (PA) may include a pad area (not shown). The pad area may protrude in the -Y direction from the peripheral area (PA) on one side of the display panel (10). A display driving unit (52) may be disposed in the pad area, and a display circuit board (51) may be connected thereto.

[0153] In one embodiment, the display panel (10) may include a bending area (not shown) that is positioned between the pad area and the display area (DA) and is bent. The pad area may be bent in the bending area, and the pad area may be positioned on the lower surface of the panel protection member (PB). The pad area may overlap with the display area (DA) in the thickness direction (Z direction) of the display panel (10). At this time, the pad area may be fixed to the panel protection member (PB) through a panel adhesive member (not shown). The panel adhesive member may be a pressure-sensitive adhesive.

[0154] In another embodiment, the peripheral area (PA) may not include the bending area. In this case, the flexible film may be bent or the display circuit board (51) may be bent. At this time, the panel adhesive member may be arranged in the same or similar manner as described above.

[0155] As another embodiment, it is also possible for both the display panel (10) and the display circuit board (51) not to be bent.

[0156] The display area (DA) may include a plurality of pixels that are display elements, and may display an image through these plurality of pixels. Each of the plurality of pixels may include subpixels. For example, the plurality of pixels may each include a red subpixel, a green subpixel, and a blue subpixel. Alternatively, the plurality of pixels may each include a red subpixel, a green subpixel, a blue subpixel, and a white subpixel.

[0157] A display circuit board (51) can be attached to one edge of the display panel (10).

[0158] The display driving unit (52) can be placed in various parts. For example, the display driving unit (52) can be placed on the substrate (100) of the display panel (10). In another embodiment, the display driving unit (52) can be placed on a flexible film. In yet another embodiment, the display driving unit (52) can be placed on a display circuit board (51). For convenience of explanation, the following description will focus on the case where the display driving unit (52) is placed on the substrate (100).

[0159] The display driving unit (52) receives control signals and power voltages and can generate and output signals and voltages to drive the display panel (10). The display driving unit (52) can be formed as an integrated circuit (IC).

[0160] A display circuit board (51) can be attached to a display panel (10). At this time, the display circuit board (51) and the display panel (10) can be connected in various ways. In one embodiment, the display circuit board (51) and the display panel (10) can be attached to each other using a flexible film. In this case, the flexible film can be connected to the display panel (10) and the display circuit board (51) through an anisotropic conductive film. The display circuit board (51) may be a flexible printed circuit board (FPCB) that can be bent, or a composite printed circuit board that includes both a rigid printed circuit board (PCB) that is rigid and does not bend well and a flexible printed circuit board.

[0161] In another embodiment, one side of the display circuit board (51) may be directly attached to one edge of the display panel (10) using an anisotropic conductive film. For convenience of explanation, the following description will focus on the case where the display circuit board (51) and the display panel (10) are connected through the anisotropic conductive film.

[0162] A touch sensor driver (53) may be disposed on the display circuit board (51). The touch sensor driver (53) may be formed as an integrated circuit. The touch sensor driver (53) may be attached to the display circuit board (51). The touch sensor driver (53) may be electrically connected to the touch electrodes of the touchscreen layer of the display panel (10) through the display circuit board (51).

[0163] The touchscreen layer (TSL) of the display panel (10) can detect a user's touch input using at least one of various touch methods, such as a resistive method or a capacitive method. For example, when the touchscreen layer (TSL) of the display panel (10) detects a user's touch input using a capacitive method, the touch sensor driving unit (53) can determine whether a user has touched by applying driving signals to driving electrodes among the touch electrodes and detecting voltages charged in the mutual capacitance (hereinafter referred to as "mutual capacitance") between the driving electrodes and the sensing electrodes through the sensing electrodes among the touch electrodes. A user's touch may include a contact touch and a proximity touch. A contact touch refers to an object such as a user's finger or a pen directly contacting a cover member placed on the touchscreen layer (TSL). A proximity touch refers to an object such as a user's finger or a pen being positioned close to the cover member, such as hovering. The touch sensor driving unit (53) transmits sensor data to the main processor according to the detected voltages, and the main processor can calculate the touch coordinates where the touch input occurred by analyzing the sensor data.

[0164] A power supply unit for supplying driving voltages to drive the pixels of the display panel (10), the scan driver, and the display driver (52) may be additionally disposed on the display circuit board (51). Alternatively, the power supply unit may be integrated with the display driver (52), in which case the display driver (52) and the power supply unit may be formed as a single integrated circuit.

[0165] The display panel (10) may include a substrate (100), a display layer (DISL), a touchscreen layer (TSL), a functional layer (OFL), and a panel protection member (PB).

[0166] A display layer (DISL) may be disposed on the substrate (100). The display layer (DISL) may be a layer that displays an image and includes pixels. The display layer (DISL) may include a circuit layer equipped with thin-film transistors, a display element layer in which display elements are disposed, and a sealing member for sealing the display element layer.

[0167] The display layer (DISL) can be divided into a display area (DA) and a peripheral area (PA). The display area (DA) may be an area where pixels are arranged to display an image. The peripheral area (PA) may be an area placed outside the display area (DA) that does not display an image. The peripheral area (PA) may be arranged to surround the display area (DA). The peripheral area (PA) may be an area from the outside of the display area (DA) to the edge of the display panel (10). In the display area (DA), not only pixels but also pixel circuits that drive the pixels, scan lines connected to the pixel circuits, data lines, power lines, etc. may be arranged. In the peripheral area (PA), a scan driver for applying scan signals to the scan lines, and fan-out lines connecting the data lines and the display driver (52) may be arranged.

[0168] A touchscreen layer (TSL) may be disposed on a display layer (DISL). The touchscreen layer (TSL) may include touch electrodes and may be a layer for detecting whether a user is touching. The touchscreen layer (TSL) may be formed directly on a sealing member of the display layer (DISL). Alternatively, the touchscreen layer (TSL) may be formed separately and then bonded to the sealing member of the display layer (DISL) through an adhesive layer such as an optically clear adhesive (OCA).

[0169] A functional layer (OFL) may be disposed on the touchscreen layer (TSL). The functional layer (OFL) may include an anti-reflection layer. The anti-reflection layer may reduce the reflectivity of light (external light) incident from the outside toward the display device (1).

[0170] In some embodiments, the anti-reflection layer may be provided as a polarizing film. The polarizing film may include a phase delay film such as a linear polarizer and a λ / 4 plate (quarter-wave plate). The phase delay film may be disposed on a touchscreen layer (TSL), and the linear polarizer may be disposed on the phase delay film.

[0171] In some embodiments, the anti-reflective layer may include a filter layer comprising a black matrix and color filters. The color filters may be arranged in consideration of the color of light emitted from each pixel of the display device (1). For example, the filter layer may include red, green, or blue color filters.

[0172] In some embodiments, the anti-reflection layer may include a destructive interference structure. The destructive interference structure may include a first reflective layer and a second reflective layer disposed on different layers. The first reflected light and the second reflected light reflected from the first reflective layer and the second reflective layer, respectively, may destructively interfere with each other, and accordingly, the external light reflectance may be reduced.

[0173] A cover member (50) may be disposed on the functional layer (OFL). The cover member (50) may be attached to the functional layer (OFL) by a transparent adhesive member, such as an optically transparent adhesive (OCA) film.

[0174] A panel protection member (PB) may be disposed on the lower surface of the display panel (10). The panel protection member (PB) may be attached to the lower surface of the display panel (10) through an adhesive member. The adhesive member may be a pressure-sensitive adhesive (PSA). The panel protection member (PB) may include at least one of a light absorption layer for absorbing light incident from the outside, a cushion layer for absorbing shock from the outside, and a heat dissipation layer for efficiently dissipating heat from the display panel (10).

[0175] A light absorption layer may be placed at the bottom of a display panel (10). The light absorption layer prevents the transmission of light, thereby preventing components placed at the bottom of the light absorption member, such as a display circuit board (51), from being visible from the top of the display panel (10). The light absorption layer may include a light-absorbing material such as a black pigment or a black dye.
