ABSTRACT:
To provide an apparatus of easily generating drive signals in correspondence with various display systems in a test device of a matrix type display device or the like, a drive signal in correspondence with each display system is generated by using at least a module for inputting an image signal, a synchronizing signal and the like, a module for subjecting the image signal to time division and a module for generating a clock signal, even when a display device to be tested is changed, a drive signal corresponding thereto can simply be generated by changing combinations of the modules or changing programs in the modules, exchanging a sequencer chip or the like and higher degree of test and analysis can be performed by adding modules for correcting the image signal, a control module or the like.
