High Efficient Anti-noise System for Embedded Advanced Touch on-Cell Display

摘要

This paper proposes a high efficient anti-noise system to improve the LCD interference of ToC type. Chunghwa Picture Tubes, LTD (CPT) has successfully solves the major issue of interference from ToC display which shown the high SNR and widely used at any image pattern. Furthermore, we also develop an "Advanced ToC" design with Sensing Display Driver (SDD) technique. We have successfully developed in ToC 3.5 inch with SDD type and ToC 4.3 inch with SDD in BAST (Brilliant Advanced Super TFT) LCD. This Advanced ToC type not only has high efficient anti-noise system but also has several advantages such as low cost, light weight and low power consumption, and so on.
