New Charge-Recycling Structure and Driving Scheme for TFT-LCD Source- Driver IC Application

چکیده
New charge-recycling structure and driving scheme for TFT-LCD source-driver IC application are proposed. The number of additional switches for the charge recycling is greatly reduced. An experimental prototype 6-bit source driver with five-level sevenphase charge recycling implemented in a 0.35-μm CMOS technology demonstrates that the quiescent current is only 3.1 mA, dynamic power saving is 75 %, and the settling time, which includes the charge-recycling and data driving, is within 25 μs.

متن کاملTFT-LCD Driver IC Design
With the rapid evolution of liquid crystal display (LCD) television (TV), there is a large demand for developing high resolution, high color depth driver integrated circuits (ICs) [13]. The panel of an LCD-TV is larger, and has higher definition, than that of a computer monitor. As a result, its color quality requires more accuracy. For example, computer monitors have 2 (262,144) or 2 (16,777,2...

− A stepwise driving method was used for reducing the AC power consumption in a TFT-LCD. The AC power takes the largest portion of the total power consumption of a TFT-LCD. Experimental results confirmed that the AC power saving efficiency reached up to 75% when a 5-stepwise driving with each step time of 2μ sec was applied to a 14.1 inchdiagonal XGA TFT-LCD. The second largest component of pow...
