16.2: Advanced TFT-LCD Data Line Reduction Method

A new multiplexing technique has been developed which eliminates 2/3 of the TFT-LCD data lines and column drivers by rearranging horizontally-placed RGB pixels vertically. The method requires three times the number of gate drivers, which in turn are integrated in α-Si silicon onto the glass substrate. This new method has been successfully tested and verified on a 12.1-inch WXGA TFT-LCD panel using only two data driver ICs.

This paper presents a thermal sensor which has been integrated onto an LCD. The sensor uses metal (Mo/Al) film as a temperature detection layer, and its fabrication requires no manufacturing process changes. The sensor shows very good linearity, sensitivity and reliability. Used with a feedback system, the thermal sensor resulted in flicker reduction of nearly 70% over the temperature range 10 °C to 70 °C.
