Method for testing LCD panel

摘要

A method for testing an LCD panel is proposed. The method includes: dividing a scanning period into a first sub-period and a second sub-period; in the first sub-period, inputting a first scanning signal to a first set of scan lines, inputting a first testing signal to a first set of data lines, and inputting a second testing signal to a second set of data lines; and in the second sub-period, inputting a second scanning signal to a second set of scan lines, inputting a first scanning signal to a first set of scan lines, inputting a second testing signal to a first set of data lines, and inputting a first testing signal to a second set of data lines. By using the procedure, the present invention uses the testing method in the cell process to test the image blur phenomenon. This can improve the testing ability and raise the yield.

主权项

1. A method for testing a liquid crystal display (LCD) panel, comprising:
in a lighting testing procedure utilized in a cell process, dividing a plurality of scan lines of the LCD panel into a first set of scan lines and a second set of scan lines, and dividing a plurality of data lines of the LCD panel into a first set of data lines and a second set of data lines; periodically inputting a scanning signal to the first set of scan lines and the second set of scan lines, where a scan period is divided into a first sub-period and a second sub-period; in the first sub-period, inputting a first scanning signal to the first set of scan lines, inputting a first testing signal to the first set of data lines, and inputting a second testing signal to the second set of data lines; in the second sub-period, inputting a second scanning signal to the second set of scan lines, inputting the second testing signal to the first set of data lines, and inputting the first testing signal to the second set of data lines; wherein the first testing signal and the second testing signal respectively provide a first display image and a second display image, and the first display image and the second display image have different colors so as to show different chessboard-like images on the liquid crystal display panel respectively in the first sub-period and the second sub-period; wherein the first testing signal provides a white image and the second testing signal provides a black image; the LCD display panel is electrically connected to a lighting testing device, and the lighting testing device is utilized to provide the first scanning signal, the second scanning signal, the first testing signal, and the second testing signal.
