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 sensing signal corresponding thereto. The controller 180 may control driving or operation of the display apparatus 100 or perform data processing, function, or operation related to an application program installed in the display apparatus 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 or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed at an inner region of the display device covered by the screen described above or near the touch screen.

Examples of the proximity sensor 141 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 case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. 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, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected through the proximity sensor 141, and further, provides visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the display apparatus 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. Detect.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the display device 100 or an application program being executed.

Meanwhile, the touch sensor and the proximity sensor described above may be independently or combined, and may be a short (or tap) touch, a long touch, a multi touch, a drag touch on a touch screen. ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. A touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, 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 detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of light change, and thus, the position information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the display apparatus 100. For example, the display unit 151 may display execution screen information of an application program driven by the display apparatus 100, or UI (User Interface) or Graphic User Interface (GUI) 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. The stereoscopic display unit may be a three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glasses-free method), a projection method (holographic method).

Referring to FIG. 2, it can be seen that a toolbar is displayed on the left corner and the bottom of the screen. In order to realize the function of the input unit 120, the toolbar may display icons for controlling various functions. It is to be understood that the shape of the toolbar illustrated in FIG. 2 and the number and type of icons included in the toolbar are merely examples and may be various. However, due to the area where the toolbar is displayed, a part of the content displayed on the screen may be hidden or a touch input such as handwriting may be restricted.

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

3 to 4 are reference diagrams for confirming change of a screen according to transparency control.

Referring to FIG. 2, the transparency control input window 151-1 may be checked. The example shown in FIG. 2 is 0% transparency. In other words, the rear screen of the toolbar is not displayed at all.

Referring to FIG. 3, it can be seen that the toolbar is in a translucent state. The example shown in FIG. 3 is 50% transparency.

Referring to FIG. 4, it can be seen that the toolbar is completely transparent. The example shown in FIG. 4 is 100% transparency. In other words, the rear screen of the toolbar is displayed as it is.

Through the transparency control input window 151-1, if the user can check the content displayed up to the part hidden by the toolbar, various inputs such as a handwriting input are 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 and essential features of the components.
