continuous grain silicon technology
CGS technology, Continuous Grain Silicon(CG- Si), is a silicon technology developed by Sharp that has a regular crystal structure with uniform grain size and arrangement compared to amorphous silicon.
Continuous Grain Silicon, or silicon with uniform grain size, is characterized by very high electron mobility, which is about 600 times that of amorphous silicon. CGS silicon can be realized in extremely thin layers of less than 3 µm. This makes it possible to produce displays in LTPS technology with smaller pixel sizes and with higher resolutions that can reproduce the UHD format.
The extremely thin CGS technology makes it possible to apply entire scarf circles directly to the display glass. Quasi a second display, which overlays the lower display. Or multi-touch screens and also other functional units such as display controller, LCD interface, memory or image processor could be applied to the glass plate. The ideas range from circuits for Bluetooth and WLANs, for the GPS system and RFID, to circuits for wireless power transmission. On the other hand, the extremely thin CGS technology can also be used in CGS projectors, where it absorbs less light than an LCD layer, for example.
