Discussion of the Related Art
Terminals may be generally classified into mobile/portable terminals and stationary terminals based on a mobility. The mobile terminals may also be classified into handheld terminals and vehicle mounted terminals depending on whether or not a user can directly carry the terminal.
Mobile terminals have increasingly more functions. Examples of the functions include data and voice communications, capturing images and video using a camera, recording audio, playing music files using a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, the mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.
As the mobile terminals have increasingly more functions, the mobile terminals have been implemented as multimedia players of multiple functions having capturing images and video, playing music files or video, game playing, receiving broadcast, etc.

As one example, the touch-sensitive input may be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the electronic device at a location that is other than the touch screen. On the other hand, the virtual key or the visual key may be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.
The sensing unit 140 is generally configured to sense one or more of internal information of the electronic device, surrounding environment information of the electronic device, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the electronic device 100 or execute data processing, a function or an operation associated with an application program installed in the electronic device based on the sensing provided by the sensing unit 140. The sensing unit 140 may be implemented using any of a variety of sensors, some of which will now be described in more detail.
The proximity sensor 141 may include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the electronic device covered by the touch screen, or near the touch screen.
The proximity sensor 141, for example, may include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, an infrared proximity sensor, and the like. When the touch screen is implemented as a capacitive touch sensor, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may also be categorized as a proximity sensor.
The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like).
In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the electronic device 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.
A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180, the controller 180, and combinations thereof.
In some embodiments, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the electronic device 100 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.
Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 151 is generally configured to output information processed in the electronic device 100. For example, the display unit 151 may display execution screen information of an application program executing at the electronic device 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images.
A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the electronic device 100. The audio output module 152 may also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the electronic device 100.
An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the electronic device 100 may include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.
A signal output by the optical output module 154 may be implemented in such a manner that the electronic device emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the electronic device senses that a user has checked the generated event, for example.
The interface unit 160 serves as an interface for external devices to be connected with the electronic device 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the electronic device 100, or transmit internal data of the electronic device 100 to such external device. The interface unit 160 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.
The identification module may be a chip that stores various information for authenticating authority of using the electronic device 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can be connected with the electronic device 100 via the interface unit 160.
When the electronic device 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the electronic device 100 or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the electronic device there through. Various command signals or power input from the cradle may operate as signals for recognizing that the electronic device is properly mounted on the cradle.

The watch type electronic device 100 according to the embodiment of the invention is a kind of the mobile terminal which the user wears on his/her wrist. The watch type electronic device 100 may include some or all of the components illustrated in
The electronic device according to the embodiment of the invention includes a band 130 which has a curved surface in a longitudinal direction or includes a flexible material. The band 130 may be configured to be detachable from a body 101 of the electronic device using a hinge pin 139.
When the band 130 is made of a material with rigidity, the band 130 may have a curved shape. Alternatively, when the band 130 is made of the flexible material, the band 130 may be configured to be flexible. Hence, the user can wear the band 130 by winding the band 130 on his/her wrist. A mounting part, on which electronic components can be mounted, is provided inside the band 130. The band substrate 185, the audio output module 152, the microphone 122, the optical output module 154, an antenna (not shown), etc. may be mounted on the mounting part.
An integrated circuit (IC) 183 is mounted on the band substrate 185 and controls the audio output module 152, the microphone 122, the optical output module 154, the wireless communication unit 110, etc. mounted on the band 130. When the IC 183 is connected to the body 101, the IC 183 may also control the body 101. The audio output module 152, the microphone 122, the optical output module 154, an antenna 117, etc. may be mounted on the band 130 separately from the band substrate 185, but may be mounted on the band substrate 185 as shown in
As shown in
The audio output module 152, the optical output module 154, and the IC 183 are positioned on the band substrate 185 disposed on one side of the band 130. Also, a terminal connected to an external battery 191 may be positioned thereon. The microphone 122, the antenna 117, the IC 183, and an internal battery 192′ may be mounted on the band substrate 185 disposed on the other side of the band 130. The above arrangement of the band substrate 185 may be changed, and more components including the components noted above may be mounted on the band substrate 185. A slit 132 extending in a longitudinal direction of the band 130 is positioned at the end of the band 130. In the embodiment of the invention, the slits 132 are respectively formed at both ends of the band 130, and each end of the band 130 is divided into two division ends 133 by the slit 132. A number of division ends 133 increases depending on an increase in a number of slits 132.
Even when the band 130 is made of the material with rigidity, the division end 133 may be made of a flexible material. The division ends 133 may bend up and down in a thickness direction of the band 130 and also may bend in different directions.
The band 130 may include a fastening hole 134 extending at the end of the band 130, i.e., at the side of the division end 133 in a width direction of the band 130. The hinge pin 139 is fastened to the fastening hole 134, thereby connecting the band 130 to the body 101. The body 101 includes a hinge hole 101b, through which the hinge pin 139 passes.
The hinge pin 139 passing through the band 130 may be formed of a conductive material and may be electrically connected to a connection ring 188 which is positioned inside the fastening hole 134 and the hinge hole 101b. The connection ring 188 is a ring-shaped member which is positioned inside the fastening hole 134 of the band 130 and is formed of the conductive material. An end of the connection ring 188 may be connected to the band substrate 185 mounted on the band 130.
A clock plate 102 including markings, an hour hand, a minute hand, a second hand, etc. is positioned on a front surface of the body 101. The body 101 includes a band fastening part 101a, which is coupled with the band 130 through the hinge pin 139, at each side of the body 101. The band fastening part 101a includes a pair of fastening protrusions, which are separated from each other by a distance corresponding to a width of the band 130, and the hinge holes 101b formed in the fastening protrusions. As described above, the hinge pin 139 is inserted into the hinge holes 101b and fastens the band 130 to the body 101.
The body 101 may be a clock body having only a function of a general wristwatch. The general wristwatch has the band fastening part 101a so as to replace a band of the wristwatch, and the band 130 can be replaced by inserting the hinge pin 139 into the hinge holes 101b of the band fastening part 101a. Thus, the electronic device according to the embodiment of the invention may be fastened to the general body 101.
In case of the body 101, on the electronic components are not separately mounted, the body 101 may include a battery 192 for driving the clock plate 102. The battery 192 may be used only in a drive of the clock plate 102. The battery included in the band 130 itself may be used to drive the electronic components of the band 130 and used to drive the display unit 151 when the display unit 151 is additionally coupled with the body 101.
Alternatively, as shown in
When the display unit 151 is used as a display of the general wristwatch, the display unit 151 is maintained in a transparent state. Only when information is output through the display unit 151, the display unit 151 may be changed to an opaque or translucent display. A touch sensor 125 is positioned on a front surface of the display unit 151 and may simultaneously perform input and output operations.
When the electronic components are mounted on the body 101, the connection ring 188 is positioned inside the hinge hole 101b for the electrical connection between the electronic components. Hence, the electronic components of the body 101 may be connected to the circuit unit 184 inside the body 101 through the connection ring 188. A function of the electronic device may be expanded through the connection between the body 101 and the bad 130.
For example, when the band 130 is connected to the body 101 having only a display function, wireless communication with a base station, or a call or transmission and reception of data through short range communication can be performed using the antenna 117 included in the band 130. Also, audio information may be output through the audio output module 152 included in the band 130.
In addition to the connection between the band 130 and the body 101 through the end of the band 130, the body 101 may be connected to an external power source through the hinge pin 139 to receive electric power, or may be connected to an external terminal, for example, a computer.

In the embodiment disclosed herein, the security module may be physical media, such as universal integrated circuit card (UICC) (for example, subscriber identification module (SIM) or universal SIM (USIM)), secure micro SD, and a sticker, and may be logical media (for example, embedded secure element (SE) embedded in the electronic device. Data exchange based on single wire protocol (SWP) may be performed between the NFC module and the security module.
When the NFC module operates in the card mode, the electronic device may transfer card information, which has been stored as in an existing IC card, to the outside. More specifically, when the electronic device storing information of a payment card (for example, a credit card and a transportation card) approaches a payment machine, NFC-enabled mobile payment may be performed. When the electronic device storing information of an access card approaches an access machine, an access approval procedure may start. The credit card, the transportation card, the access card, etc. may be mounted on the security module in the applet, and the security module may store information of the cards mounted thereon. The information of the payment card may include at least one of a card number, balance, and details of usage. The information of the access card may include at least one of a user name, a user ID number, and an access history.
When the NFC module operates in the reader mode, the electronic device may read data from an external tag. In this instance, data the electronic device receives from the tag may be coded into a data exchange format defined in the NFC forum. Further, the NFC forum defines four record types. More specifically, the NFC forum defines four record type definitions (RTDs) including smart poster, text, uniform resource identifier (URI), and general control. When the data received from the tag is the smart poster type, the controller 180 may execute browser (for example, internet browser). When the data received from the tag is the text type, the controller 180 may execute a text viewer. When the data received from the tag is the URI type, the controller 180 may execute browser or make a call. When the data received from the tag is the general control type, the controller 180 may perform a proper operation depending on control contents.
When the NFC module operates in the P2P mode, the electronic device may perform P2P communication with other electronic device. In this instance, logical link control protocol (LLCP) may be applied to the P2P communication. A connection may be produced between the electronic device and the other electronic device for the P2P communication. The connection may be divided into a connectionless mode, in which one packet switching is performed and ended, and a connection-oriented mode, in which packet switching is successively performed. Through the P2P communication, data, for example, electronic business cards, contact information, digital photographs, and URL, Bluetooth, a setup parameter for WiFi, etc. may be exchanged through the P2P communication. Because an available distance of the NFC communication is short, the P2P mode may be efficiently used to exchange data of small size.

The display module 260 may include electric lines RL and CL in the active area AA. The electric lines RL and CL may be thin film transistor (TFT) lines. The electric lines RL and CL may include rows RL and columns CL. The rows RL and the columns CL may cross each other. In this instance, the electric lines RL and CL may not be formed in the second deactive area DA2. This may mean that the electric lines RL and CL are formed while avoiding the second deactive area DA2.
In another terms, the electric lines RL and CL may perform a switching function in the active area AA. A switching operation may be performed at coordinates of a matrix formed through the crossing of the rows RL and the columns CL. When the shaft hole 262 is formed in the middle of the display module 260, the matrix coordinates cannot be electrically formed at a location of the shaft hole 262. This is because the shaft hole 262 may be formed as a physically empty space. More specifically, when the shaft hole 262 is formed in the middle of the display module 260, the second deactive area DA2 may be formed around the shaft hole 262. Hence, the electrical matrix coordinates cannot be formed around the shaft hole 262. In other words, the TFT cannot be formed in the shaft hole 262 or the second deactive area DA2.
Because the electric lines RL and CL are formed while avoiding the shaft hole 262 or the second deactive area DA2, current flowing through the electric lines RL and CL may flow throughout the display module 260 without cutoff of the current due to the shaft hole 262 or the second deactive area DA2.

A backlight unit may provide light for the display panel 2602 at one side of the display panel 2602. The backlight unit may provide light for the display panel 2602 from the rear or a lower surface of the display panel 2602. The rear or the lower surface of the display panel 2602 means the side or the surface opposite the surface of the display panel 2602 observed from the outside of the electronic device. The backlight unit may include, for example, a light source 2610, a light guide plate 2607, and optical layers 2604, 2605, and 2606.

The light source 2610 may be positioned on the side of the backlight unit. A direction of light the light source 2610 provides may be different from a direction of light the backlight unit provides for the display panel 2602. For example, the backlight unit may provide light for the display panel 2602 from the rear of the display panel 2602. In this instance, the light source 2610 may provide light in a direction vertical to (or in a direction crossing) the direction of light provided by the backlight unit. Namely, light provided by the light source 2610 changes its path inside the backlight unit and may finally travel toward the display panel 2602. In this instance, the light guide plate 2607 may change a path of light provided by the light source 2610. The light source 2610 may be a light emitting diode (LED) element, for example.
A flexible printed circuit board (FPCB) 2611 may be electrically connected to the light source 2610. The FPCB 2611 may supply the electric power received from the power supply unit 190 to the light source 2610 and may control a switching operation of the light source 2610. When the plurality of light sources 2610 are used, the FPCB 2611 may have a plurality of branches electrically connected to the plurality of light sources 2610.
The light guide plate 2607 may be embedded in the backlight unit. The light guide plate 2607 may be positioned in the rear of the display panel 2602. The light source 2610 may be positioned on one side of the light guide plate 2607. In this instance, the light source 2610 may be separated from the light guide plate 2607 by a predetermined distance. For example, when the backlight unit is positioned under the display panel 2602, the light guide plate 2607 may be positioned under the display panel 2602, and the light source 2610 may be positioned on the side of the light guide plate 2607. In this instance, the light guide plate 2607 may change a path of light provided by the light source 2610 and may make the light travel toward the display panel 2602.
A reflective layer 2608 may be positioned under the light guide plate 2607. The reflective layer 2608 may be positioned adjacent to a lower surface of the light guide plate 2607, or may contact the lower surface of the light guide plate 2607. The reflective layer 2608 may make light, which is incident on the inside of the light guide plate 2607 from the light source 2610, travel toward an upper part of the light guide plate 2607. The reflective layer 2608. The reflective layer 2608 may be formed by processing the lower surface of the light guide plate 2607. The reflective layer 2608 may have a pattern 2608p, so as to improve efficiency of the reflective layer 2608, which makes light incident on the inside of the light guide plate 2607 from the light source 2610 travel toward the upper part of the light guide plate 2607. The pattern 2608p may be formed in the reflective layer 2608. The pattern 2608p may be formed between the light guide plate 2607 and the reflective layer 2608 and may provide a different refractive index for the light guide plate 2607.
The optical layers 2604, 2605, and 2606 may be positioned on the light guide plate 2607. The optical layers 2604, 2605, and 2606 may be positioned adjacent to an upper surface of the light guide plate 2607 and may contact the upper surface of the light guide plate 2607. The optical layers 2604, 2605, and 2606 may focus or diffuse light emitted from the light guide plate 2607, thereby uniformly providing light for the display panel 2602. The optical layers 2604, 2605, and 2606 may include a diffuser 2606 and prisms 2604 and 2605. The diffuser 2606 may be positioned adjacent to the upper surface of the light guide plate 2607, positioned on the upper surface of the light guide plate 2607, or may contact the upper surface of the light guide plate 2607. The diffuser 2606 may evenly distribute light emitted from the light guide plate 2607. One diffuser 2606 or the plurality of diffusers 2606 may be used. The prisms 2604 and 2605 may be positioned adjacent to an upper surface of the diffuser 2606, positioned on the upper surface of the diffuser 2606, or may contact the upper surface of the diffuser 2606. The prisms 2604 and 2605 may concentrate light diffused and emitted from the diffuser 2606 in one direction. Namely, the prisms 2604 and 2605 may provide linearity, which makes light distributed by the diffuser 2606 travel toward the display panel 2602. One prism or the plurality of prisms may be used. In other words, light emitted from the light source 2610 may change its travelling direction through the light guide plate 2607 and the reflective layer 2608, may pass through the optical layers 2604, 2605, and 2606, and may be provided for the display panel 2602.
A frame 2612 may support the components of the display module 260, or may contribute to the structural stability or the coupling stability of the display module 260 by contacting or fixing the components of the display module 260. One frame 2612 or a plurality of frames 2612, 2613, and 2609 may be used.
A cover 2614 may cover at least a portion of the frame 2612 and at least a portion of the components of the display module 260 supported by the frame 2612. The cover 2614 may cover the perimeter of the display module 260, a portion of the front surface or the back surface of the display module 260, or the entire display module 260. The cover 2614 may be positioned along an outer perimeter of the display module 260.
Hence, the display panel 2602 may have a thin profile structure. The display panel 2602 may provide the screen of excellent image quality in spite of the thin profile structure of the display panel 2602. If there occurs a change in the backlight unit or the display panel 2602, the image quality of the screen provided by the display panel 2602 may change. This means that a physical change generated in the display panel 2602 or the backlight unit may result in a change in the image quality of the screen provided by the display panel 2602.

In terms of the light path, light provided by the light source 2610 may enter the light guide plate 2607. In this instance, the light entering the light guide plate 2607 may be reflected on the light guide plate 2607 by the reflective layer 2608. The light emitted on the light guide plate 2607 may travel toward the display panel 2602 by the optical layers 2604, 2605, and 2606. In this instance, a path of a portion of the light, which is provided by the light source 2610 and enters the light guide plate 2607, may change due to the shaft hole 262. Namely, the path of the light, which is provided by the light source 2610, enters the light guide plate 2607, and travels toward the display panel 2602, may be blocked. In other words, a shadow area SA may be formed in the display module 260. The shadow area SA leads to a reduction in the image quality of the display module 260.

The first to third light sources may be positioned adjacent to the side of the light guide plate 2607, or may be sequentially positioned along the perimeter of the display module 260. Further, the fourth to sixth light sources may be positioned adjacent to the side of the light guide plate 2607, or may be sequentially positioned along the perimeter of the display module 260. The fourth to sixth light sources may be positioned opposite the first to third light sources. In other words, the first to third light sources may be symmetrical to the fourth to sixth light sources with respect to the shaft hole 262.
The first to third light sources may be positioned within the range of about 120° with respect to the shaft hole 262, and the fourth to sixth light sources may be positioned within the range of about 120° with respect to the shaft hole 262. In another example, the first to third light sources may be positioned within the range of about 90° with respect to the shaft hole 262, and the fourth to sixth light sources may be positioned within the range of about 90° with respect to the shaft hole 262. The first to third light sources may be positioned opposite the fourth to sixth sources. In other words, the first to third light sources may be symmetrical to the fourth to sixth light sources with respect to the shaft hole 262.
The shadow area SA may be prevented from being formed in the display module 260 through the above-described arrangement of the plurality of light sources. Namely, as described above, the arrangement of the plurality of light sources can greatly improve the image quality of the display module 260.

A plate 2615 may be provided in the rear of the frame 2612. The FPCB 2611 may be positioned between the plate 2615 and the frame 2612 and may be electrically connected to the light source 2610. For example, the FPCB 2611 may be positioned between the plate 2615 and the frame 2612, and one side or both sides of the FPCB 2611 may extend from the FPCB 2611 to the light source 2610.
Referring to
The FPCB 2611 may have a shape corresponding to the FPCB groove 2611h. The fact that the FPCB 2611 corresponds to the FPCB groove 2611h means that the FPCB 2611 may be entirely positioned in the FPCB groove 2611h. For example, the almost entire portion of the FPCB 2611 may be positioned in the FPCB groove 2611h formed in the plate 2615, and the remaining portion of the FPCB 2611 may be positioned in the FPCB groove 2611h formed in the frame 2612. The FPCB 2611 may be electrically connected to the light sources 2610. Hence, a thickness of the display module 260 can be smaller. The fact that the thickness of the display module 260 is smaller may mean that it is difficult to design or arrange the components of the display module 260. The above configuration of the display module 260 described with reference to
