Abstract

The automotive display system requires high reliability to the longterm usage and the wide operation temperature range. The performance of the display system relies on the characteristics of a‐Si:H transistors in the driver circuit. We here propose the new a‐Si:H integrated gate driver circuit, where the self‐compensation transistors are intentionally added to stabilize the bias conditions at the extreme environment. The additional pull‐down transistors, only operating at low temperatures, compensate the decreased oncurrent of the circuit at the extreme condition. This consequently improves the reliability of the output characteristics for the display system.
