IMAGE-CLOCK ADJUSTING CIRCUIT AND METHOD

摘要

An image-clock adjusting circuit and a method thereof are provided to prevent color rolling phenomenon with relatively low cost. A phase comparator(31) compares the phase of the vertical synchronizing signal and the received electric source signal, and generates one or more phase comparison signal. A clock controller(32) controls a first clock width of the pixel clock signal by receiving the phase comparator signal, and the vertical synchronizing signal. A timing generator(32) adjusts the vertical synchronizing signal, and synchronize the vertical synchronizing signal with the power signal by receiving pixel clock signal.
