Abstract
The present invention discloses a data transfer system and method for a matrix display. The system includes a multi-level timing controller connected to a multi-level input data driver via a multi-level signal bus. A digital input signal necessary for image display is converted into a multi-level signal display data output by an encoder in the multi-level timing controller, transferred to the multi-level input data driver through the multi-level signal bus, and converted into a data driving signal for a display panel by a decoder. According to the present invention, due to the multiple levels, the number of lines between the controller and the data driver can be considerably decreased and data transfer frequency is reduced.
