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 an audio device which adopts a panel for displaying images at a frame rate, the method comprising:

operating the panel at a first frame rate frequency when the audio device is not processing audio messages;

operating the panel at a second frame rate frequency higher than the first frame rate frequency in response to the audio device processing an audio message associated with receiving or making a phone call; and

reducing current frame rate frequency from the second frame rate frequency to the first frame rate frequency in response to termination of processing the audio message;

wherein the frame rate is measured by reversal of polarity of pixel voltages in alternating intervals.

2. The method of claim 1 being a method for driving an audio device which adopts a serial/parallel RGB (red, green, blue) interface type panel.

3. The method of claim 1 being a method for driving an audio 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.

5. The method of claim 1 being a method for driving a cellular phone.

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

7. A method for driving an audio device, which adopts a panel for displaying images, said method comprising;

operating the panel at a first frame rate frequency when the audio device is not outputting sound corresponding to information received by the audio device associated with a phone call;

operating the panel at a second frame rate frequency higher than the first frame rate frequency in response to the audio device outputting the sound; and

reducing current frame rate frequency of the panel from the second frame rate frequency to the first frame rate frequency in response to termination of the outputting of the sound.

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

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

10. An audio system comprising:

a panel for displaying images at a frame rate;

means for operating the panel at a first frame rate frequency when the audio system is not processing an audio message associated with receiving or making a phone call;

means for operating the panel at a second frame rate frequency higher than the first frame rate frequency in response to the audio system processing the audio message; and

reducing current frame rate frequency from the second frame rate frequency to the first frame rate frequency in response to termination of processing the audio message;

wherein the frame rate is measured by reversal of polarity of pixel voltages in alternating intervals.

11. The audio system of claim 10 wherein the panel is a serial/parallel RGB interface type panel.

12. The audio system of claim 10 wherein the panel is a CPU interface type panel.

13. The audio system of claim 10 being a PDA or a smart phone.

14. The audio system of claim 10 being a cellular phone.

15. The audio system of claim 10 wherein the panel is a TFT LCD panel.

16. The audio system of claim 10 wherein the first frame rate frequency is 60 Hz.
