Abstract

Methods for driving devices capable of displaying images and processing audio messages are provided. A representative method comprises: operating a device capable of displaying images and processing audio messages at a first operating frequency when the device is not processing audio messages; and operating the device at a second operating frequency higher than the first frequency when the device is processing audio messages.

Claims

1. A method for driving a device capable of displaying images and processing audio messages comprising:

operating a device capable of displaying images and processing audio messages at a first operating frequency when the device is not processing audio messages; and

operating the device at a second operating frequency higher than the first frequency when the device is processing audio messages.

2. The method of claim 1 being a method for driving a device which adopts a serial/parallel RGB interface type panel.

3. The method of claim 1 being a method for driving a device which adopts a CPU (central processing unit) interface type panel.

4. The method of claim 1 being a method for driving a PDA (personal data assistant) or a smart phone capable of displaying images and processing audio messages.

5. The method of claim 1 being a method for driving a cellular phone capable of displaying images and processing audio messages.

6. The method of claim 1 being a method for driving a device adopting a TFT LCD panel.

7. A method for driving a device capable of displaying images and processing audio messages, said method comprising:

operating the device at a first operating frequency when the device is not outputting sound corresponding to information received by the device; and

operating the device at a second operating frequency higher than the first operating frequency response to the device outputting such sound.

8. The method of claim 7, further comprising:

reducing the operating frequency of the device responsive to termination of the outputting of the sound.

9. The method of claim 8, wherein reducing comprises reducing the operating frequency to the first operating frequency.

10. The method of claim 7, wherein the device is a cellular phone.

11. The method of claim 7, wherein the information received is a carried by a cellular phone signal.

12. A system capable of displaying images and processing audio messages comprising:

means for operating the system at a first operating frequency when the system is not processing audio messages; and

means for operating the system at a second operating frequency higher than the first operating frequency when the system is processing audio messages.

13. The system of claim 12 further comprising a serial/parallel RGB interface type panel.

14. The system of claim 12 further comprising a CPU interface type panel.

15. The system of claim 12 being a PDA or a smart phone.

16. The system of claim 12 being a cellular phone.

17. The system of claim 12 further comprising a TFT LCD panel for displaying images.
