Abstract
Abstract— A new low‐image‐lag drive method is proposed for large‐size LCTVs, taking into account the input signal and inter‐field differential signal dependence of the response time. It was shown that the gray‐level response time was 30–60 ms, which is 2–3 times as long as the ON‐OFF bi‐level response time, and was expressed as a linear function of the input voltage. With the new level adaptive overdrive (LAO) method, the response time was reduced to 17 ms, which is about one‐half to one‐third that of the conventional method and is satisfactory for TV applications. A 10.4‐in. panel has been used to verify the effect of LAO on image quality. Moving images have been clearly observed using the LAO method.
