0.91 inch In Cell Display, In Cell Touch Panel OLED 128x32

Model No. REX012832M-CTP

This new 0.91” graphical OLED display features in-cell PCAP touch panel. Structure wise, in-cell touch has the touch sensor embedded in OLED display. Thanks to its single layer structure, the display is thinner and brighter than module with out-cell touch. The in-cell touch panel of this model supports 4-area touch detection and horizontal scrollbar.

This In-Cell Touch OLED display boasts 10000:1 high contrast ratio. Logic voltage ranges from 3V-3.5V (typical 3.3V). The display is working within -40°C~+80°C temperature range; storage temperature covers from -40°C~85°C. OLED display with in-cell PCAP touch is a good fit for wearable device, smart appliances, medical equipment, etc.

Symbol

Function

VCI

Power supply pin for touch analog driving. VCI must be greater than or equal to VDD.

VSS

Ground pin.

VCC

Power Supply for Display. Most positive voltage. Connect to external source.

VSL

This is segment voltage (output low level) reference pin.
When external VSL is not used, connect externally to VSS. When external VSL is used, connect with resistor and diode to ground

DCDCEN0

Enable output pin for external DCDC circuit. NC if not used

DCDCEN1

Enable input pin for external DCDC circuit. Tie low if not used.

VDD

Power supply pin for core logic operation.

This pin outputs RAM write synchronization signal.
It should be kept NC if it is not used.

DCS

This pin is the chip select input connecting to the MCU for display interface.

TCS

This pin is the chip select input connecting to the MCU for touch.

RES#

This pin is the reset signal input for display interface.

TRES

This pin is the reset signal input for touch.

This pin is Data/Command control pin for display interface.
In I2C mode, this pin acts as SA0 for slave address selection.

E/RD#

In I2C mode, this pin acts as SA1 for slave address selection.

IRQ

Interrupt signal for touch reporting.

TD0

Serial Data Input/Output and clock for Touch
In SPI mode TD2 serves as SDOUT, TD1 serves as SDIN, and TD0 serves as the serial clock SCLK.
In I2C mode TD2 and TD1 should be tied together and serve as SDA and TD0 is the serial clock SCL. External pull up resistors.

TD1

TD2

VSS

Ground pin.

The serial clock input for display interface.

The serial data input for display interface.

BS3

VCOMH

COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
