Abstract: “The technology of manufacturing display devices such as CRT, LCD & LED displays are advancing at a very fast pace. Due to change in technology, the manufacturing process requirement are also changing. In this paper, we will analyse the multi format signal generators, which are utilised and has the capability to generate signals, compatible for display inspection of SDTV, HDTV, Monitors display inspections. The major job in display inspection is white balance of the device. White balancing is performed on Monochrome signals which are corrupted by intermittent colour transients. The aim of this study is to reduce the colour transients in Grey Scale signals, by observing the waveforms of Grey Scale patterns, generated by a multi format pattern generator. The analysis of waveforms includes the study of waveforms related to Y/colour difference, greyscale , chrominance, and sync level components.”
