Abstract: A method to eliminate caterpillar phenomenon in a scanning LED display is disclosed, wherein each scan line comprises a USW(N) for charging the scan line(N) and a DSW(N) for discharging the scan line(N), the method comprising: turning on the USW(N) to charge the scan line(N) for a first time interval; turning on the DSW(N) to discharge the scan line(N) for a second pre-determined time interval; and turning off the DSW(N) after the second pre-determined time interval is elapsed.

Abstract: A GAMMA adjustment method for a multi-channel driver of a monitor and device thereof are provided. The GAMMA adjustment method converts an m-bit input signal of a high bit signal corresponding to an m-bit simulated GAMMA curve into an n-bit signal of a low bit signal. Then the n-bit signal together with an n-bit input signal are input to a driver component. The driver component compares the two low-bit signals to generate a PWM driver signal supplied to a data channel of the monitor. Since the two n-bit signals of the driver component are of low quantity bit, the driver chooses n-bit digital driver components to greatly reduce an overall layout area of the driver and further to reduce manufacture cost.
