Abstract
Methods and related liquid crystal display devices are disclosed that reduce/avoid a tearing effect in displayed images. A scan time of a scan clock signal of a display is detected. A write time of a write clock signal that writes data into a memory for display on the display is detected. The write time is regulated in response to a comparison of the scan time of the scan clock signal to the write time of the write clock signal.
Claims17
A method of operating a display device, the method comprising:
- detecting a scan time of a scan clock signal of the display;
- detecting a write time of a write clock signal that writes data into a memory for display on the display;
- and
- regulating the write time in response to a comparison of the scan time to the write time.

A liquid crystal display (LCD) device comprising:
- a LCD panel;
- a controller that is configured to receive image data from circuitry external to the LCD device and to generate a write clock signal defining a write time;
- and
- an LCD 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 LCD driver scans the image signal into the LCD panel at a rate defined by the scan time of the scan clock signal to display an image on the LCD panel, and
- 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.
