Abstract (en)

[origin: DE10314268B3] The pixel and sub-pixel defect simulation method uses a programmable pixel defect simulation unit (3) for replacing the red-green-blue signal (10) obtained from the video image data stream with a modified red-green-blue signal (11) which simulates pixel or sub-pixel defects, the timing and duration of the signal replacement controlled for obtaining the pixel or sub-pixel defect at a required point on the display screen. An independent claim for a circuit device for simulation of pixel and sub-pixel defects for a matrix-addressed display is also included.
