15.2: A 10.4‐in. XGA Low‐Temperature Poly‐Si TFT‐LCD for Mobile PC Applications

Abstract

Abstract A 10.4‐inch TFT‐LCD with XGA resolution has been developed using low‐temperature poly‐Si technology. We have newly developed a circuit construction and a driving method for this LCD. Positive and negative video signals are separately applied to video buslines from two D‐A conversion ICS. The integrated data‐line driver circuits operate with four multiplexing‐blocks and eight‐phase parallel video inputs. The integrated scan‐line driver circuits have shift registers operating at 10V voltage with redundancy function. High aperture ratio of 61% was realized. These result in small data‐line driver circuit width of 3.7mm, low module power consumption of 2.3W, and high reliability.
