Low Temperature Polysilicon (LTPS) transistor manufacturing is more complex than amorphous silicon (a-Si) and metal oxide transistor fabrication, requiring additional steps and processes.
While this increases cost, LTPS can deliver hundred-times the mobility of a-Si screens and much higher resolution and pixel density, making it an optimal solution for OLED-based mobile devices, ultra-definition TV and retina display smart phones and tablets. The introduction of larger-scale LTPS plasma enhanced chemical vapor deposition (PECVD) equipment will allow leading panel makers to scale LTPS technology to larger substrates to drive down the cost of these displays.
