INTRODUCTION

The S6D0110 is 1-chip solution for TFT-LCD panel: source driver with built-in memory, gate driver, power IC are integrated on one chip. This IC can display to a maximum of 132-RGB x 176-dot graphics on 65k-color TFT panel.

The S6D0110 also supports bit-operation functions, 8/16-bit high-speed bus interface, and high-speed RAM-write functions enable efficient data transfer and high-speed rewriting of data to the internal GRAM.

FEATURES

? 132-RGB x 176-dot TFT-LCD display controller/driver IC for 65,536 colors (396ch-source driver/176ch-gate driver)

? 16-/8-bit high-speed bus interface and serial peripheral interface (SPI)

? High-speed burst-RAM write function

? Writing to a window-RAM address area by using a window-address function

? Bit-operation functions for graphic processing

- Write-data mask functions in bit units

- Logical operation in pixel unit and conditional write function

? Various color-display control functions

- 65,536 colors can be displayed at the same time (gamma adjust included)

- Vertical scroll display function in raster-row units

? Internal RAM capacity: 132 x 16 x 176 = 371,712 bits

? Internal oscillation and hardware reset

? Structure for TFT-display retention volume (Cst/Cadd structure)

? Alternating functions for TFT-display counter-electrode power supply

- N-line alternating drive of Vcom (Vgoff is also available for N-line alternating drive for Cadd)

? Internal power supply circuit

- Step-up circuit: five to nine times, positive-polarity inversion

- Adjustment of Vcom(Vgoff) amplitude: internal 22-level digital potentiometer

? Operating voltage

? Applying voltage

- VDD to VSS = 1.8 to 2.5 V (non-regulating) (logic voltage range – non-regulated) VDD3 to VSS = 2.3 to 3.3 V (regulating) (logic voltage range – regulated)

- Vci to VSS = 2.5 to 3.3 V (internal reference power-supply voltage)

- Vci1 to VSS = 1.7 to 2.75 V (2.5 x 0.68 ~ 2.75) (power supply for step-up circuits)

? Generating voltage

- For the source driver: AVDD to VSS = 3.5 to 5.5V (power supply for liquid crystal output circuits) GVDD to VSS = 3.0 to 5.0V (reference power supply for grayscale voltages)

- For the gate driver: VGH to VGL = 14 to 30 V, VGH to VSS = +7.0 to +20 V, VgoffL = (VGL+0.5) to –7.5V, VgoffH = ~ to -1.5V

- For the TFT-display counter electrode: Vcom amplitude(max) = 6V, VcomH to VSS(max) = GVDD VcomL to VSS(max) = 1.0 V to -Vci + 0.5 V
