Full-Color Gray-Scale Processor
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.
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.
