Specifically, the display device 1 according to the embodiment of the present invention includes a display unit 11 for displaying a plurality of images by dividing one screen into a plurality of areas, a display unit 11 for displaying a pointing signal And a plurality of signal sensing units 12 for sensing the signal. The plurality of signal sensing units 12 may determine whether or not the pointing signal is sensed according to whether the reception angle of the pointing signal is within a predetermined allowable range. For example, when the receiving angle of the pointing signal falls within the allowable range of the signal detecting unit 12, the pointing signal can be detected. On the other hand, when the receiving angle of the pointing signal exceeds the allowable range of the signal detecting unit 12 The pointing signal can not be detected. The display device 1 can determine the area to which the user points by using the plurality of signal sensing parts 12 corresponding to the respective areas. For example, the area where the receiving angle of the pointing signal is the largest among the plurality of signal detecting units 12 within the allowable range may be determined as a pointing area by the user.

1, the screen of the display unit 11 includes four areas: a first screen 111, a second screen 112, a third screen 113, and a fourth screen 114 ) So that different images can be displayed for each area. If the pointing signal from the pointing device 2 is received in the area of the second screen 112, the number of the signal sensing parts 12 in which the receiving angle of the pointing signal falls within the allowable range It is possible to determine that the two screens 112 are pointing.

2, the screen of the display unit 11 includes nine areas: a first screen 111, a second screen 112, a third screen 113, a fourth screen 114, the fifth screen 115, the sixth screen 116, the seventh screen 117, the eighth screen 118 and the ninth screen 119 to display different images for respective areas . If the position where the pointing signal from the pointing device 2 is received belongs to the area of the ninth screen 119, the number of the signal sensing parts 12 in which the reception angle of the pointing signal falls within the allowable range, It is possible to determine that the screen 119 is pointing. The display apparatus 1 can perform an operation corresponding to the pointing signal with respect to the image displayed in the area determined by the user to be pointing.

3 is a block diagram showing a configuration of a display device 1 according to an embodiment of the present invention. The display device 1 may be implemented as a TV, a monitor, or the like. The display device 1 may include a display unit 11, a plurality of signal sensing units 12, and a control unit 13.

The display unit 11 can display a plurality of images on a plurality of areas of the screen. The display device 1 can set the number of divided areas or the size of divided areas from one screen. The display unit 11 can display an image in various ways such as a panel type LCD, a PDP, an OLED, and a UHD. The display unit 11 displays an image based on the image signal processed by the image processing. The video signal may be, for example, a broadcast signal of a TV. The broadcast signal can be broadcast by a method of over-the-air broadcast, cable broadcast, satellite broadcast, and the like. The broadcast signal has a plurality of channels. As another embodiment, the video signal may be received, for example, from a video device such as a DVD player, a BD player, received from a PC, received via a network such as the Internet, received via a network such as Bluetooth Wi- Or may be received from a memory such as a storage medium. Image processing may include, for example, modulation, demodulation, multiplexing, demultiplexing, analog to digital conversion, digital to analog conversion, decoding, encoding, image enhancement, scaling, and the like.

The signal sensing unit 12 is arranged to correspond to a plurality of areas, and senses a pointing signal from the pointing device. The signal sensing units 12 may be arranged in the same number in each area or may be arranged such that the signal sensing units 12 are spaced the same distance. For example, when the pointing device is an infrared ray transmitter for outputting infrared ray, the signal detector 12 may be an infrared ray receiver for receiving infrared ray output from the pointing device.

4 is a block diagram showing a configuration of a display device 1 according to another embodiment of the present invention. The display device 1 may include a display unit 11, a signal sensing unit 12, a control unit 13, and a UI generation unit 14.

The UI generation unit 14 displays an item that allows selection of any one of a plurality of areas displayed on the screen. For example, when the screen is divided into two areas and two images are displayed, as shown in Fig. 7, each area can be displayed as items of the first screen and the second screen. The control unit 13 can determine the area to point to the area corresponding to the UI item selected by the user.

5 to 6 are views showing details of an operation of determining an area to which a display device 1 according to an embodiment of the present invention is pointing. The screen of the display unit 11 is divided into a plurality of areas, that is, a first screen 111, a second screen 112, a third screen 113 and a fourth screen 114, Images can be displayed. The plurality of signal sensing units 12 are arranged along the edge of the screen and are divided into respective areas corresponding to the first screen 111, the second screen 112, the third screen 113 and the fourth screen 114 Respectively. The plurality of signal sensing units 12 may sense a pointing signal received on the screen at each fixed position.

First, with reference to FIG. 5, determination of an area to be pointed according to the degree of reception of a pointing signal will be described. The degree of reception of the pointing signal is higher in the region where the signal sensing portion 12 having the reception angle of the pointing signal among the plurality of signal sensing portions 12 corresponding to each region is within the allowable range . For example, since the reception angle of the signal sensing unit 12 for sensing the pointing signal determines whether or not the reception angle of the pointing signal is within the allowable range at the fixed position of the signal sensing unit 12, The closer the distance from the reception position of the signal to the signal sensing unit 12, the higher the reception degree, and the longer the distance, the lower the reception degree. 5, when the position where the pointing signal from the pointing device 2 is received belongs to the area of the first screen 111, the signal sensing part 12 (see FIG. 5) in which the reception angle of the pointing signal falls within the allowable range, , That is, the first screen 111 having the highest degree of reception of the pointing signal can be determined to be pointing.

Next, with reference to FIG. 6, description will be made of determination of a pointing area when there are a plurality of areas having similar degree of reception of the pointing signal. 6, when the pointing signal from the pointing device 2 is received in the boundary area between the first screen 111 and the second screen 112, the first screen 111 and the second screen 112 Since the number of the signal sensing units 12 in which the reception angle of the pointing signal of the second screen 112 is within the allowable range is similar to the reception sensitivity of the pointing signal among the first screen 111 and the second screen 112 It may be difficult to determine the highest area. In this case, as shown in Fig. 7, after displaying the UI items 31 and 32 of the first and second screens having similar degree of reception of the pointing signal, an area corresponding to the UI item selected by the user is pointed As shown in FIG.

Referring to Fig. 8, it is explained that the display apparatus 1 receives and operates the pointing signal from the pointing device. First, in operation S201, the display unit 11 displays a plurality of images in a plurality of areas of the screen. For example, as shown in FIG. 1, the screen of the display unit 11 may be divided into four regions to display four images, or the screen of the display unit 11 may be divided into nine regions And nine images can be displayed. Next, in operation S202, a plurality of signal sensing units 12 arranged to correspond to a plurality of regions sense the pointing signal from the pointing device. Next, in operation S203, the control unit 13 determines which area of the plurality of areas the pointing signal sensed by the plurality of signal sensing units 12 points to. For example, as shown in FIG. 1, when the pointing signal from the pointing device 2 is received in the area of the second screen 112, It is possible to determine that the second screen 112 having the largest number of points 12 is pointing. 2, when the position at which the pointing signal from the pointing device 2 is received belongs to the area of the ninth screen 119, the signal sensing unit 120, which receives the pointing signal within the allowable range, It is possible to determine to point to the ninth screen 119 having the greatest number of game players 12.

Next, in operation S403, it is determined whether or not there are a plurality of areas having similar degree of reception of the detected pointing signal. If there are a plurality of areas having similar reception levels, the control unit 13 determines an area to be pointed according to the user's selection (S404). 6, the position where the pointing signal is received from the pointing device 2 corresponds to the boundary area between the first screen 111 and the second screen 112, and the first screen 111, And the number of the signal sensing units 12 in which the reception angle of the pointing signal of the second screen 112 is within the allowable range is similar to that of the reception of the pointing signal among the first screen 111 and the second screen 112 If it is difficult to determine the area having the highest degree, the area to be pointed can be determined according to the user's selection. If there is no similar area, the controller 13 determines a pointing area of the plurality of areas to which pointing of the pointing signal is highest (step S405). Next, the control unit 13 performs an operation corresponding to the pointing signal with respect to the image displayed in the determined area (S406).
