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.

[LC11011-141]
Features
鈥?Handles 8-bits of input data (256-scale data) for each of
the RGB colors.
鈥?Operating mode selection of three, four, or six bit driver
outputs
鈥?Realizes reduced resolution loss (as compared to
dithering techniques) by using intra- and inter-frame
error diffusion processing.
鈥?Supports both 5 V and low voltage (3.3 V) operation.
鈥?Operates with arbitrary clock frequencies up to 50 MHz
(at 5 V) or up to 30 MHz (at 3.3 V).
鈥?Can operate independently of the number of displayed
pixels since internal operation is controlled by the
horizontal and vertical synchronization signals.
