Implementation of TFT inspection system using the common unified device architecture (CUDA) on modern graphics hardware

Nowadays, computational power of graphics hardware is strong enough to be used in many applications requiring parallel computing. It can be used any other areas even unrelated to the graphics displays. Following these trends, we adapted this general purpose graphics processing unit (GPGPU) for thin film transistor liquid crystal displays (TFT-LCD) inspection. In this paper, we describe practical system components and the implementation including compute unified device architecture (CUDA) programming. An experimental result compares to the previous system which uses CPU as a main processor.
