PD16430A
1/2, 1/3, 1/4 DUTY LCD CONTROLLER/DRIVER
The
碌
PD16430A is an LCD controller/driver that enables the display of LCDs of 1/2 duty, 1/3 duty and 1/4 duty
cycle.
The LCD controller contained in the
碌
PD16430A employs serial data transfer and uses an automatic increment
function for data addresses which eliminates the need to set addresses newly each time.
The LCD driver uses a medium voltage output (14 V max.), which enables higher contrast and a wider viewing angle
even with a 1/3 or 1/4 duty cycle.
By using an on-chip drive bias circuit, it is possible to eliminate the need for external resistors.
