The method described has general application to the dynamic row by row image analysis of a matrix of scanned points. Although it will be described with reference to the testing of plasma display panels for defective display points, the methodology could apply to image processing, character recognition and linear scanning applications. Connectivity, chain set-up, dynamic memory allocation and chaining algorithms are described in some detail. As is well known, a plasma display panel consists of man crosspoint each of which can be used to display a picture element (pel) Current methods of testing display panels test each crosspoint to determine whether it can be switched on and switched off (erased).
