LCD Driver
The LCD driver can directly drive an LCD panel with 1/8 duty and 1/4 bias or with 1/16 duty and 1/5 bias, this function is
selected by the flag VBIAS. The frame of this LCD driver may select a 64Hz or 128Hz by flag FRAME.
LCD driver uses the voltage of the VLCD pin as the power source. To adjust the view angle, the programmer can select
the real LCD power by the flags VCON0 and VCON1. The flag LCDON is used to turn On/Off the LCD display. Note that
the VLCD voltage must equal or be less than VDD.
Segment/Common to I/O Selection
For the flexible purpose, some of the LCD COMMON and SEGMENT pins are shared with the input/output port.
Both of the HT95L400/40P and HT95L300/30P provide 12 pins to be selected to SEGMENT output pins or I/O pins.
HT95L200/20P provides 8 pins to be selected for COMMON output pins or I/O pins. Both of the HT95L100/10P and
HT95L000/00P provide 4 pins to be selected for SEGMENT output pins or I/O pins.
All of the HT95L400/40P, HT95L300/30P and HT95L200/20P provide the LCD COMMON output pins for 8 COMMON
or 16 COMMON. The description of the relation between segment pins, common pins and I/O pins are shown on the
below.
