v General Description
ML1001 static LCD COG (chip on glass) driver is 40 segments LCD driver with gold bump. It can be
cascaded to form a single piece of 80 or 120 segments LCD drivers. It targets at custom TN LCD COG
Module product which requires the best quality of TN LCD technology. With the use of ML1001 series
driver, it offers the best contrast, the widest viewing angle, the widest range of operating voltage and the
widest range of operating temperature when compared to the multiplex method.
Our ML1001 includes an internal 32kHz oscillator, a 40-bit shift register, a 40-bit data register, a 16-bit
segment driver, a 24-bit segment driver, two common drivers, a blink control circuit, a power-up reset
circuit and a frequency divider which offer the necessary clock signals for Blink control, segment &
common driver circuit.
Through the DIN pin, the display data is serially shifted into the 40-bit shift register at the rising edge of
DCLK signal. The display data, which is going to be displayed on the attached LCD, is then stored in the
40-bit data register at the rising edge of the LOAD signal.
Other features like blinking of the display data by the BEN and BCLK, disable the internal oscillator by
the OEN, input an external clock signal to the FIN, and enable or disable the segment and common driver
by the SEN1, SEN2, CEN1A and CEN1B, are included.
