Method for detecting defects in an active matrix liquid crystal display panel |
摘要 |
Disclosed herein is a method for detecting a defect of an active matrix liquid crystal panel, the method including a step of inputting a data signal for displaying an image having a luminance level lower than a maximum luminance level to a first signal line while inputting a data signal for displaying a black image to a second signal line and a third signal line, the second signal line and the third signal line adjoining the first signal line, thereby causing pixels corresponding to the first signal line to display a single color. According to the method of the present invention, any defective pixel is displayed darker than normal, owing to a decrease in the transmittance, so that point defects such as S-D leak defects can be easily detected.
