TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
COLUMN ROW DRIVER LSI FOR A DOT MATRIX GRAPHIC LCD
The TOSHIBA T6K04 is a driver for a small or medium scale dot
matrix graphic LCD. It has a 8 bit interface circuit. It generates
all timing signals for display with on−chip oscillator. It receives 8
bit data from a MPU, laches the data to on−chip RAM, and
display the image on LCD (The data on the display RAM
correspond to the dots of display.). It has 128 column driver
outputs and 64 row driver outputs so as to drive 128 dots by 64
dots LCD on a single. The other functions, It has resistors to
divide bias voltage, power supply OP−Amp, DC−DC converter
(doubler, tripler, quadrupler) and contrast control circuit so as to
drive LCD with a single power supply.
