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 equivalent 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 dithering 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 parallel-output, and serial input/output operating modes

• 40MHz (parallel input/output), 65 MHz (serial input, parallel output), or 50MHz (serial input/output) maximum clock frequency

• Can operate independently of the number of displayed pixels since internal operation is controlled by the horizontal and vertical synchronization signals.

• Power-save function to stop the internal operation processing circuits, and output only the clock, sync signals and control signals

• Supports 5V input signals at 3.3V supply voltage
