In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

First, a reference voltage V _ref of a mobile terminal 100 according to an embodiment of the present invention is applied at 2.8 V, and at a very low temperature (-50 ° C) 25 ° C) and 0V at a very high temperature (120 ° C), so that the mobile terminal 100 knows the state of the main battery 191.

If there is no main battery 191, it is recognized as 2.8 V which is the same as the reference voltage V _ref .

Using this principle, a comparator IC is introduced and the threshold voltage (IC threshold voltage) at the comparator is set to 2.6 V (= V3) so that the temperature at the state where the main battery 191 is mounted The voltage in the state of being mounted at normal temperature during the process of being 2.8 V (= V2) which is the voltage in the removed state of the main battery 191 in the vicinity of the room temperature where the voltage at the sensing electrode 193 is 1.4 V is 1.4 The comparator output voltage level in the comparator goes from high to low when the voltage between the voltage V2 in the removed state (V = V1) and the voltage in the removed state (2.8V = V2) And sends a signal to the mobile terminal 100 to recognize that the main battery 191 has been removed. At this time, the main battery 191 becomes the primary main battery 191.

In contrast, when the secondary main battery 191 is inserted, the voltage at the connection point between the main battery 191 and the mobile terminal 100 is 2.8 V The comparator output voltage level is recognized as Low to High when the output voltage of the mobile terminal 100 is equal to or higher than V1 And recognizes that the secondary main battery 191 is inserted.

The temperature sensing electrode 193 of the main battery 191 includes a variable resistor and the resistance R _th of the variable resistor R and the resistance R of the mobile terminal 100, The voltage V _out at the connection point between the main battery 191 and the mobile terminal 100 is calculated by the reference voltage V _ref of the main battery 191.
