Samsung 

132 RGB SOURCE & 176 GATE DRIVER WITH INTERNAL RAM FOR 65K COLORS TFT-LCD

FEATURES

S6D0110

Preliminary

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

Low-power operation supports:

− Power-save functions such as the standby mode and sleep mode

− Partial LCD drive of two screens in any position

− Maximum 12-times step-up circuit for liquid crystal drive voltage

− Voltage followers to decrease direct current flow in the LCD drive breeder-resistors

− Equalizing function for the switching performance of step-up circuits and operational amplifiers

N-raster row inversion drive (Reverse the polarity of driving voltage in every selected raster row is

possible)

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
