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.

When this pin is low, the LC11011-141 performs no gray scale processing, but rather simply passes the input signals through unchanged. When a low level input on this pin is sampled on the rising edge of the clock, the IC will begin the output of unchanged data two clock cycles later.

Display dot clock input. Data is processed according to this clock signal. Input pins for red, green and blue scale data. SRDATA7, SGDATA7, and SBDATA7 are the MSBs. SRDATA0, SGDATA0, and SBDATA0 are the LSBs. Horizontal and vertical synchronization signal inputs. These are the sources for the Hsync and Vsync signals. These are also used to control data processing. These are low level active signals. Horizontal data valid period signal input. Set this pin high during periods when the horizontal data is valid. If this signal is not used, tie it high, and set the input data to zero during the horizontal blanking period. LCD control inputs. Input control signals that must be matched to the data signal timing. These are the sources for the CTL signals. If the CTL [0:1] signals are not used, there is no need to input the SCTL [0:1] signals. CLKSEL is the dot clock output selection. It is used to select the output mode of the dot clock signal output pin. If CLKSEL is low: A signal with the same phase as the SCLK pin is output from the CLK pin. If CLKSEL is high: A signal with the opposite phase from the SCLK pin is output from the CLKB pin. Continued on next page. No. 5041-5/7 LC11011-141 Continued from preceding page.
