SEG (column) driver outputs. Support up to 104 x RGB pixels.
Leave unused drivers open-circuit.
COM (row) driver outputs. Support up to 80 rows. Leave unused COM
drivers open-circuit.
When designing LCM, always start from COM1. If the LCM has N pixel
rows and N is less than 80, set CEN to be N-1, and leave COM drivers
[N+1 ~ 80] open-circuit.
Test control. This pin has on-chip pull-up/down resistor. Leave it open
during normal operation.
TST4 is also used as one of the high voltage programming power supply
for OTP operation. For COG design with OTP options, please wire out
TST4 with an ITO trace resistance of 200 or less.
Test I/O pins. Leave these pins open during normal use.
