Full-Color Gray-Scale Processor
Overview
The LC11014-241 is a pseudo gray-scale processor for
TFT-LCD panel displays. It allows TFT-LCD panels with
3, 4, 5 or 6-bit input digital drivers to display the equiva-
lent of 16.7 million colors. It can also be used with XGA
panels in 2-pixel parallel input/output mode.

Features
• Handles 8 bits of input data (256-level gray scale data)
for each of the RGB colors
• Realizes reduced resolution loss (as compared to dither-
ing techniques) by using intra-frame and inter-frame
error diffusion processing
• Incorporates a new full-coloration algorithm, formerly
best done using computers
• Operating mode selection of outputs for 3, 4, 5, or 6-bit
drivers
• Selectable 2-pixel parallel input/output, serial-input par-
allel-output, and serial input/output operating modes
• 40MHz (parallel input/output), 65 MHz (serial input,
parallel output), or 50MHz (serial input/output) maxi-
mum clock frequency
• Can operate independently of the number of displayed
pixels since internal operation is controlled by the hori-
zontal and vertical synchronization signals.
• Power-save function to stop the internal operation pro-
cessing circuits, and output only the clock, sync signals
and control signals
• Supports 5V input signals at 3.3V supply voltage
