Patent ID: 8421722

Claim:
A method of transmitting data from a timing controller to a source driving device in a liquid crystal display, comprising the steps of: (a) providing a setup/hold time; (b) transmitting a test pattern from the timing controller to the source driving device using the setup/hold time, wherein the source driving device stores a test pattern corresponding to the transmitted test pattern; (c) returning an acknowledge signal from the source driving device to the timing controller when the test pattern is successfully received and verified by the source driving device; (d) providing a new setup/hold time and repeating Steps (b) and (c) using the new setup/hold time until the test pattern is successfully received by the source driving device; and (e) transmitting image data from the timing controller to the source driving device using the new setup/hold time upon receipt of the acknowledge signal, wherein the image data are different from the test pattern.
