Meanwhile, the sensing unit 140 senses at least one of information in the display device, surrounding environment information surrounding the display device, and user information, and generates a corresponding sensing signal. The control unit 180 may control driving or operation of the display device 100 or may perform data processing, function, or operation related to an application program installed in the display device 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the display device or the proximity sensor 141 near the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. 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. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Further, the control unit 180 can control the display device 100 to process different operations or data (or information) according to whether the touch to the same point on the touch screen is a proximity touch or a contact touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. 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). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the operation state of the current display device 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. 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.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. 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.

The display unit 151 displays (outputs) information to be processed in the display device 100. For example, the display unit 151 may display execution screen information of an application program driven by the display device 100, or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

In addition, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image. In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

2 is an exemplary view of a toolbar displayed on the display unit of the display device according to the present specification;

Referring to FIG. 2, it can be seen that a tool bar is displayed at the left corner and the bottom of the screen. In order to realize the function of the input unit 120, the tool bar may display icons capable of controlling various functions. It should be understood that the form of the toolbar shown in FIG. 2 and the number and types of icons included are only exemplary and may vary. However, due to the area where the tool bar is displayed, a part of the content displayed on the screen may be hidden, or a touch input such as handwriting may be limited.

The toolbar according to the present specification may be displayed with an input window for controlling the transparency of the screen.

FIGS. 3 to 4 are reference views for confirming the change of the screen according to the transparency control.

Referring to FIG. 2, the transparency control input window 151-1 can be confirmed. The example shown in Fig. 2 is transparency of 0%. That is, the back screen of the toolbar is not displayed at all.

Referring to FIG. 3, it can be seen that the tool bar is in a translucent state. The example shown in Fig. 3 has transparency of 50%.

Referring to FIG. 4, it can be seen that the tool bar is in a completely transparent state. The example shown in Fig. 4 is 100% transparency. That is, the rear screen of the toolbar is displayed as it is.

Through the transparency control input window 151-1, if the user can confirm contents displayed up to the portion hidden by the tool bar, various input such as handwriting input is possible.

It will be apparent to those skilled in the art that the present specification may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present specification should be determined by rational interpretation of the appended claims, and all changes within the equivalency range of the specification are included in the scope of the present invention.
