To generate a sensing signal for controlling the operation of the portable terminal 100. For example, when the portable terminal 100 is in the form of a slide phone, whether the slide phone is opened or closed may be sensed. In addition, it is responsible for sensing functions related to whether the power supply unit 190 is supplied with power or whether the interface unit 170 is coupled to an external device. The sensing unit 140 may include a proximity sensor 141. This will be described later with reference to the touch screen.
The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, wired / wireless headset ports, external charger ports, wired / wireless data ports, memory card ports, ports for connecting devices with identification modules, audio input / output (I / O) ports, Video I / O (Input / Output) port, earphone port, etc. may be included. Here, the identification module is a chip that stores a variety of information for authenticating the use right of the mobile terminal 100, a user identification module (UIM), Subscriber Identity Module (SIM) ), A Universal Subscriber Identity Module (“USIM”), and the like.

Examples of the proximity sensor include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.
In the high frequency oscillation type proximity sensor, when the sensing object approaches the sensor sensing surface in the state of oscillating high frequency wave of oscillation circuit, the oscillation amplitude of the oscillation circuit is reduced or stopped, and this change is converted into an electrical signal. The presence or absence of a will be detected. Therefore, even if a non-metallic material comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.
Even if the proximity sensor is not mounted, the touch screen may be configured to detect proximity of the pointer by a change in electric field according to proximity of the pointer when the touch screen is capacitive.
Therefore, when the pointer is not in contact but is in close proximity on the touch screen, the position of the pointer and the distance between the pointer and the touch screen may be detected. Hereinafter, for convenience of explanation, the act of allowing the pointer to be located close to the touch screen to recognize that the pointer is located on the touch screen is referred to as a "proximity touch", and the act of actually touching the pointer on the touch screen. Will be referred to as "contact touch". In addition, the position of the proximity touch with the pointer on the touch screen refers to a position where the pointer is perpendicular to the touch screen when the pointer is in close proximity touch.
The proximity sensor detects proximity touch and proximity touch patterns (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) Information corresponding to the touch operation and the proximity touch pattern may be output on the touch screen.

Examples of events occurring in the mobile terminal include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than an audio signal or a video signal. For example, the signal may be output in the form of vibration. When a call signal is received or a message is received, the alarm unit 153 may output a vibration to inform this. Alternatively, when a key signal is input, the alarm unit 153 may output a vibration in response to the key signal input. Through the vibration output as described above, the user can recognize the occurrence of the event. Of course, the signal for event occurrence notification may be output through the display unit 151 or the voice output module 152.

It becomes possible.
According to FIG. 7, the upper edge part 421 of the longitudinal side of the outer frame 420 is folded, and the thickness is double. The upper edge portion 421 of the outer frame 420 can effectively prevent the degradation of the rigidity when the bottom support 432 is excluded.
FIG. 8 is a perspective view illustrating that the resin filling unit is filled between the display panel and the outer frame, and FIG. 9 is a partial cross-sectional perspective view of the display module in which the resin filling unit is filled as shown in FIG. 8.
The resin filling part 440 is filled in the gap between the vertical side of the outer frame 420 and the display panel 410. More specifically, the peripheral surface of the vertical side of the display panel 410 is contacted and fixed by the resin filling part 440.
The resin filling part 440 is injected into the liquid phase in a narrow gap between the display panel 410 and the outer frame 420 and is cured by ultraviolet rays or the like. Therefore, the display panel 410 can be prevented from flowing in the left and right directions in the outer frame 420, and the buffer property of the resin itself can be expected. In addition, the method of filling the gap by curing the resin has the advantage that it is easier to assemble than the case of attaching the preformed cushioning member and can fill the gap more completely.
The resin filling part 440 is charged while traveling along the gap between the display panel 410 and the outer frame 420 by a filling tool.
The resin filling part 440 may be formed of a black-based opaque resin material to effectively block light emitted from the circumferential surface of the display panel 410.
The display module and the portable terminal having the same described above are not limited to the configuration and method of the described embodiments, but the embodiments may be all or part of each of the embodiments so that various modifications may be made. It may be configured in combination.
