Abstract

This article proposes a source driver integrated circuit (SD-IC) with a pixel compensator designed to mini- mize both silicon area and power consumption for organic light-emitting diode (OLED) displays. The proposed SD-IC is capable of driving ultrahigh-deﬁnition (UHD) active-matrix OLED (AMOLED) panels with a one-horizontal-time (1-H time) of 7.2µs while supporting a variable refresh rate (VRR). During VRR activation, the compensator senses the characteristics of the driving thin-ﬁlm transistor
