Patent ID: 7782310

Claim:
A method for displaying frame, suitable for displaying a plurality of frame data in an image signal on a display panel, wherein a vertical blank period is located between every two adjacent frame data in the image signal, the method for displaying frame comprising: displaying a background frame on the display panel during the vertical blank period of the image signal; and displaying one of the frame data on the display panel during the non-vertical blank period of the image signal, wherein the step of displaying the background frame on the display panel during the vertical blank period of the image signal comprises: determining the quantity of a plurality of clock pulses; adding the clock pulses into a gate clock during the vertical blank period, wherein the gate clock is used to provide the timing required by the gate driver of the display panel to drive gate lines; and providing a gate start pulse to the gate driver of the display panel during the vertical blank period; wherein the step of determining the quantity of the clock pulses comprises: calculating the difference between the number of the gate lines of the display panel and the number of the horizontal lines of the frame data, and dividing the result by 2, so as to obtain a first numerical value; subtracting a predetermined value from the first numerical value, to serve as the quantitative value of the clock pulses in the gate clock during the vertical blank period after the gate start pulse; and adding the clock pulses with a quantity of at least twice of the predetermined value into the gate clock during the vertical blank period and before the timing of the gate start pulse.
