Switch frequency adjusting system and method for burst mode of liquid crystal display

A switch frequency adjusting system for a burst mode of a liquid crystal display, comprising:

• a receiver for receiving a scan frequency value from a signal source;
• an adjuster electrically connected to the receiver, for deriving a switch frequency value of the burst mode according to the scan frequency value, wherein the switch frequency value of the burst mode equals the scan frequency value multiplied by a multiple (N+0.5), wherein N is a positive number, and a tolerance range of the switch frequency value of the burst mode is less than ±20 Hz;
• and
• a transmitter electrically connected to the adjuster, for transmitting the switch frequency value to a lamp controller.

A liquid crystal display, comprising:

• a liquid crystal display panel, for receiving a scan frequency value to scan the display;
• at least one lamp, for providing light to the liquid crystal display;
• a lamp controller, for controlling the brightness of the lamp according to a switch frequency value of a burst mode;
• and
• a switch frequency adjusting system, comprising:
• a receiver for receiving a scan frequency value from a signal source;
• an adjuster electrically connected to the receiver, for obtaining the switch frequency value according to the scan frequency value, wherein the switch frequency value equals the scan frequency value multiplied by a multiple (N+0.5), wherein N is a positive number, wherein a tolerable range of the switch frequency value is less than ±20 Hz;
• and
• a transmitter electrically connected to the adjuster, for transmitting the switch frequency value to the lamp controller.
