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 mobile terminal or in proximity to the touch screen, which is covered by 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.

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).

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.

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 wireless communication unit 210 may be embedded in the housing, and may transmit and receive images to / from the wireless communication unit 210 of other devices. When the image is received from the other device through the wireless communication unit 210, the projector control unit 280 outputs the received image to the liquid crystal screen in the optical engine 220 so that the received image can be projected on an external screen . The other device may preferably be a mobile terminal.

Specifically, the wireless communication unit 210 can transmit and receive a video image to / from the mobile terminal through a Wi-Di (Wireless Display) communication method.

At this time, the projector control unit may correct the pre-projection image so that the distortion of the projected image is compensated. Preferably, the correction of the pre-projection image may be performed in the image correction unit 281 included in the projector control unit. The pre-projection image is an image input to the optical engine 220 for projection.

When at least one light, for example a ray point beam, is emitted from the light source, the emitted light is converged on a mirror (not shown) of the optical engine. The optical engine optically processes the light converged on the mirror, then reflects the light, and scans the screen so that the image is output.

In Fig. 2D, a plurality of lenses included in the fisheye lens are shown, and Figs. 2E and 2F show an embodiment in which the projection angle of the projector is extended by the fisheye lens.

As shown in FIGS. 2d to 2f, the phenomenon that light emitted from the light source spreads by a fish-eye lens can be realized by three lenses. Each lens curvature is provided as a means to spread light. The emitted light ray may be composed of concave and convex which is refracted by a concave and convex primary lens and refracted by a secondary or tertiary lens. The radius of the secondary curvature is smaller than the radius of the tertiary curvature so that the spread of the light can be made uniform.
