    Abstract: An apparatus for channel balancing of a multi-channel analog-to-digital converter of a digital image display comprises a red, a green and a blue analog-to-digital converter for respectively receiving a red, a green and a blue analog signal of an image signal wherein the analog-to-digital converters respectively sample the red, green and blue analog signals through a sampling clock signal and output a corresponding digital signal. A phase difference processing unit is used for estimating the phase differences among the digital signals and outputting corresponding time delay signals according to the phase differences. A clock delay compensation unit is used for receiving the time delay signals and respectively compensating the time delays of the sampling clock signals of the analog-to-digital converters according to the time delay signals, thereby decreasing the phase differences among the digital signals. The present invention also provides a method for channel balancing of a multi-channel analog-to-digital converter of a digital image display.

    Abstract: A method for generating a video clock and an associated target image frame is disclosed. The method generates an output clock signal for outputting a target image frame to a panel according to a frame pixel number and a vertical synchronization signal (Vsync). The target image frame corresponds to a source image frame. The frame pixel number is the number of total pixels included in a predetermined frame format, and the Vsync signal is an input Vsync signal or an output Vsync signal. The period of the output clock signal is the result of the period of the Vsync divided by the frame pixel number. In this manner, the format of the target image frame can remain substantially fixed, and is substantially equal to the predetermined frame format.
