  • Switch frequency adjusting system and method for burst mode of liquid crystal display
    Patent number: 7256762
    Abstract: The invention relates to a method for dynamically adjusting a switch frequency of a burst mode for a liquid crystal display. The method of the invention comprises the steps of: (a) receiving a scan frequency value from a signal source; (b) deriving a switch frequency value of the burst mode according to the scan frequency value; and (c) transmitting the switch frequency value to a lamp controller. According to the method of the invention, the switch frequency value can be obtained through calculation or by a look-up table. The stitch frequency value preferably equals a scan frequency value multiplied by a multiple (N+0.5), wherein N is a positive number. A tolerable range of the switch frequency value of the burst mode is ±20 Hz. The method of the invention utilizes various scan frequency values to adjust the switch frequency value.
