Abstract This paper presents thermally adaptive driving (TAD) technology for response time compensation (RTC) of an LCD with an integrated sensor. The TAD is comprised of analog sensor signal conditioning and a digital feedback algorithm. The integrated thermal sensor provides accurate temperature measurement of the liquid crystal layer. The TAD controller has an 8‐step look‐up‐table (LUT), and compensates response time based on the panel temperature. The TAD system reduces response time by nearly 50% over the temperature range 0 ° −; 60 °C.
