Abstract
A timing controller is provided. A data enable signal in a timing control module is regenerated by a signal regenerating module. A number of vertical valid display rows is regenerated as a vertical valid display period. A total charge time of all rows of pixels in each frame can be increased effectively. A horizontal blanking period is changed sequentially in a row-by-row manner, thereby compensating charge effects of rows of pixels accurately.

A timing controller, comprising:
- a timing control module configured to transmit a data enable signal and pixel data corresponding to the data enable signal and configured to process the pixel data under control of a pixel clock frequency;
- and
- a signal regenerating module configured to be connected to the timing control module to regenerate the data enable signal, wherein the signal regenerating module comprises:
