Description

HIGH VOLTAGE LCD DRIVER OUTPUT

SEG1 ~

SEG312

SEG (column) driver outputs. Support up to 104 x RGB pixels.

Leave unused drivers open-circuit.

COM1 ~

COM80

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.

MISC. PINS

VDDX

Auxiliary VDD. These pins are connected to the main VDD bus on chip. They

are provided to facilitate chip configurations in COG and COF applications.

These pins should not be used to provide VDD power to the chip. It is not

necessary to connect VDDX to main VDD externally.

TST4

I/HV

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 Ω or less.

TST2

I/O

Test I/O pins. Leave these pins open during normal use.

TP[5:1]

Test control. Leave these pins open during normal use.

Note: Several control registers will specify “0 based index” for COM and SEG electrodes. In those

situations, COMX or SEGX will correspond to index X-1, and the value ranges for those index

registers will be 0~79 for COM and 0~311 for SEG.
