The guide frame on which the IR sensor module 940 is mounted may be rotatable. A small motor 970 is provided adjacent to the guide frame 920, and the small motor 970 is rotated to change the inclination angle.

The guide frame may include a plate 927 configured to be rotatable.

Further, it may further include a small motor 970 formed adjacent to the plate 927 and adapted to rotate the plate 927.

The IR sensor module 940 may be mounted on the plate 927 and may be configured to vary the area of the IR beam as the small motor 970 rotates.

The small motor 970 can rotate the small motor 970 in the control unit when the light amount or the signal of the IR beam sensed by the IR sensor module 940 becomes lower than a reference value.

18 is a graph showing the amount of light in the display front space according to the angle formed between the display and the IR beam of the IR light emitting unit.

According to the graph, it can be seen that as the angle of inclination of the IR beam from the IR light emitting part with the display increases, the amount of IR light per square mm increases in the unrecognized area of the overall display. However, when the inclination angle exceeds 45 degrees, it can be seen that the amount of light in the unrecognized area is reduced.

As a result of this experiment, when the display size is 8 inches, the unrecognized area does not exist when the inclination angle is 15 degrees to 25 degrees. When the display size is 13 inches, the inclination angle is 25 degrees to 40 degrees There is no unrecognized area.

Also, depending on the size of the display, the unrecognized area disappears from an IR beam emitted from the IR light emitting part to the display at an angle of about 5 degrees or more, or more than a recognition area distance of 120 mm at the front of the display. In addition, from about 15 degrees or more, the entire unrecognized area disappears beyond the recognition area distance of 70 mm on the front surface of the display.

Accordingly, it is possible to manufacture the display device by fixing the angle formed by the IR beam emitted from the IR light emitting part to the display depending on the size of the display. In addition, it is also possible to make the angle by which the IR beam emerges, as in some of the above embodiments.

The above-described image display apparatuses are not limited to the configurations and methods of the embodiments described above, but the embodiments may be modified such that all or some of the embodiments are selectively combined .
