METHOD AND APPARATUS FOR CALIBRATING LIQUID CRYSTAL DISPLAY DEVICE

摘要

The embodiment of the invention provides a method and an apparatus for calibrating a liquid crystal display device. The liquid crystal display device comprises a pixel array, each pixel of the pixel array comprises electrodes in inclined arrangement, wherein an inclined orientation of the electrodes in pixels of odd rows is different with an inclined orientation of the electrodes in pixels of even rows; the method comprises: measuring brightness of the pixels of odd rows in a plurality of gray scales and brightness of the pixels of even rows in the plurality of gray scales respectively in a predetermined direction; and adjusting data line voltages of the pixels of odd rows and/or data line voltages of the pixels of even rows, such that in the predetermined direction, in each one of the plurality of gray scales, brightness of the pixels of odd rows is equal to brightness of the pixels of even rows.

主权项

1. A method of calibrating a liquid crystal display device comprising the steps of:
measuring a first brightness of an odd row of pixels of the liquid crystal display device from a predetermined direction for each of a plurality of gray scales, the odd row of pixels having a first data line voltage that can be adjusted to adjust the first brightness of the odd row of pixels; measuring a second brightness of an even row of pixels of the liquid crystal display device from the predetermined direction for each of the plurality of gray scales, the even row of pixels having a second data line voltage that can be adjusted to adjust the second brightness of the even row of pixels; and adjusting at least one of the first data line voltage and the second data line voltage such that the first brightness and the second brightness are equal for each of the plurality of gray scales when measured from the predetermined direction; wherein the liquid crystal display device comprises a pixel array having a plurality of odd rows of pixels and a plurality of even rows of pixels, wherein each pixel of the pixel array comprises one or more electrodes oriented at an angle to a row of pixels, wherein the electrodes of an odd row of pixels have a first orientation and the electrodes of an even row of pixels have a second orientation different from the first orientation.
