DISPLAY DEFECTS DETECTION METHOD FOR FLAT-PANEL DISPLAY DEVICE

PROBLEM TO BE SOLVED: To provide a display defects detection method for a flat-panel display device which can detect faulty gray scales, a type of display defects in an FPD, mechanically, with high precision, and in a short time. SOLUTION: In an image in which faulty gray scales, occurring caused by...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a display defects detection method for a flat-panel display device which can detect faulty gray scales, a type of display defects in an FPD, mechanically, with high precision, and in a short time. SOLUTION: In an image in which faulty gray scales, occurring caused by faulty data transmission in a flat-panel display device with n-bit gray-scale display using a method in which data signals are transmitted from a signal source to the flat-panel display device, is displayed, whether the gray scales are good or bad is judged by inspecting only two patterns, or a (2n-1-1) gray scale and a 2n-1gray scale, which are adjacent gray scales.
