Abstract:
1. A liquid crystal display device comprising: a liquid crystal display panel; a controller that is configured to receive image data from circuitry external to the liquid crystal display device and to generate a write clock signal defining a write time; and a liquid crystal display driver that is configured to store image data from the controller at a rate defined by the write time of the write clock signal, to generate a scan clock signal having a scan time, and to generate an image signal in response to the stored image data, the image signal having a rate defined by the scan time of the scan clock signal, wherein the liquid crystal display driver scans the image signal into the liquid crystal display panel at the rate defined by the scan time of the scan clock signal to display an image on the liquid crystal display panel, wherein the controller regulates the write time of the write clock signal in response to a comparison of the scan time of the scan clock signal to the write time of the write clock signal, wherein the controller detects the write time of the write clock signal, detects the scan time of the scan clock of the scan clock signal, compares the scan time of the scan clock signal to the write time of the write clock signal, and adjusts the write time of the write clock signal in response to the comparison, and wherein the controller responds to the write time being greater than the scan time by reducing the write time, and responds to the write time being less than the scan time by increasing the write time, so that the controller adjusts the write time of the write clock signal to be equal to the scan time of the scan clock signal.
