LC11011-141

Ordering number : EN*5041A CMOS LSI LC11011-141 Computer Image Signal Processing Full-Color Gray-Scale Processor Preliminaly Overview The LC11011-141 is a pseudo gray scale processor for TFT LCD. It allows LCD panels with inputs of three to six bits per RGB to display the equivalent of 16.7 million colors. Package Dimensions unit: mm 3151-QFP100E [LC11011-141] Features Handles 8-bits of input data (256-scale data) for each of the RGB colors. Operating mode selection of three, four, or six bit driver outputs Realizes reduced resolution loss (as compared to dithering techniques) by using intra- and inter-frame error diffusion processing. Supports both 5 V and low voltage (3.3 V) operation. Operates with arbitrary clock frequencies up to 50 MHz (at 5 V) or up to 30 MHz (at 3.3 V). Can operate independently of the number of displayed pixels since internal operation is controlled by the horizontal and vertical synchronization signals.
