Abstract

The present invention relates to device and method for controlling a wireless image display device, in which a communication state between wireless transmitter/receiver is informed to a user and a transmission side Tx antenna and a reception side Rx antenna are controlled for providing an optimum transmission/reception radio.

Claims

1. A method for controlling a wireless image display device comprising the steps of:

wirelessly receiving a data transmitted from a transmitter which provides an image signal;

determining a transmission/reception ratio of the data received;

comparing the transmission/reception ratio of the data to a preset reference value; and

adjusting the antenna according to a result of the comparison.

2. The method as claimed in claim 1, wherein the preset reference value of the transmission/reception ratio is set by a user as the user desires, or set in a default.

3. The method as claimed in claim 1, wherein the step of antenna adjusting includes antenna adjustment automatic or manual modes.

4. The method as claimed in claim 1, wherein, if the determined transmission/reception ratio is below the preset reference value as the result of the comparison, adjusts up/down and left/right direction moving position values and a rotation angle value of the antenna.

5. The method as claimed in claim 4, wherein the adjusted up/down and left/right direction moving position values and the rotation angle value of the antenna and a data transmission/reception ratio transmitted through the antenna adjusted are stored.

6. The method as claimed in claim 5, wherein the stored up/down and left/right direction moving position values and the rotation angle value of the antenna corresponding to the data transmission/reception ratio are reference to adjustment of antenna.

7. The method as claimed in claim 1, further comprising the steps of displaying a transmission/reception ratio or antenna position and direction changed by the antenna adjustment with an OSD data.

8. The method as claimed in claim 1, if the transmission/reception ratio is high the preset reference value, determining whether the user desires to re-adjust the antenna or not;

if the user desires to re-adjust the antenna, re-adjusting the antenna, and storing the transmission/reception ratio of a data obtained by the re-adjustment;

comparing the transmission/reception ratio obtained according to the re-adjustment of the antenna to the transmission/reception ratio in storage; and

adjusting the antenna to a state of having a higher transmission/reception ratio according to a result of the comparison.

9. The method as claimed in claim 7, wherein the displayed position information of antenna is image or numerical value.

10. The method as claimed in claim 1, wherein, if the transmission/reception ratio is below the preset reference value as a result of the comparison, not only the antenna at the receiver, but also the antenna at the transmitter, can be adjusted by means of wireless communication.

11. A device for controlling a wireless image display device comprising:

a receiver for receiving a data from a wireless transmitter which provides an image signal through an antenna;

a transmission/reception ratio determining unit for determining a transmission/reception ratio of the received data;

a memory for storing a preset reference value which meets the transmission/reception ratio; and

a control unit for comparing the transmission/reception ratio of the received data to the preset reference value and adjusting the antenna according to a result of the comparison.

12. The device as claimed in claim 11, wherein the preset value of the transmission/reception ratio is set by a user as the user desires, or set in a default.

13. The device as claimed in claim 11, wherein the control unit sets one of antenna adjustment automatic or manual modes.

14. The device as claimed in claim 11, wherein, if the determined transmission/reception ratio is below the preset reference value as the result of the comparison, the control unit adjusts up/down and left/right direction moving position values and a rotation angle value of the antenna.

15. The device as claimed in claim 11, wherein the memory stores a adjusted up/down and left/right direction moving position values and a rotation angle value of the antenna and a data transmission/reception ratio transmitted through the antenna adjusted.

16. The device as claimed in claim 15, wherein the stored up/down and left/right direction moving position values and the rotation angle value of the antenna corresponding to the data transmission/reception ratio in the memory are reference to adjustment of antenna.

17. The device as claimed in claim 11, further comprising a display unit for displaying a transmission/reception ratio or antenna position and direction changed by the antenna adjustment with an OSD data.

18. The device as claimed in claim 11, wherein the control unit, if the user desires to re-adjust the antenna, re-adjusts the antenna, stores the transmission/reception ratio of a data obtained by the re-adjustment, compares the transmission/reception ratio obtained according to the re-adjustment of the antenna to the transmission/reception ratio in storage, and makes the wireless data communication to be performed in a state of the antenna having a high transmission/reception ratio.

19. The device as claimed in claim 17, wherein the displayed position information of antenna is image or numerical value.

20. The device as claimed in claim 11, wherein the control unit controls a motor mounted to a lower end of the antenna according to the control value for moving an antenna shaft up/down.
