Display overdrive method

The OD method for a display is comprised of the following steps:

• having image data provided with gray scale presentation range containing multiple continuously distributed gray scale codes into a display;
• a corresponding gray scale range being set up to contain multiple continuously distributed gray scale codes with each gray scale code within the gray scale presentation range being related to that within the corresponding gray scale range;
• gray scale codes within the corresponding gray scale range being transmitted to an image process module adapted with an OD module to overdrive pixels in the display and a virtual bit module to upgrade gray scale bit;
• and
• the image data being judged as still or dynamite picture and the gamma voltage being overdriven and outputted by the OD module;
• and
• wherein the OD module includes a frame memory unit to store the preceding image, an image comparator to compare images, an OD comparison list process unit to process OD numerical values, a comparison list read only memory unit and a multiplexer to pass image data;
• the image comparator reading the preceding image within the frame memory unit to judge if the frame of the image date relates to a still or dynamic picture;
• the picture being sent to the multiplexer to pass the data in case of a still picture;
• and the OD reference list process unit reading the gamma voltage corresponded to the gray scale code in the reference list read only memory unit and transmitting it to the multiplexer to pass the data in case of a dynamic picture.
