Intuitive use of smart applications: With the REX128128D COG OLED module, Raystar adds a rotary switch module, that also uses a projected capacitive touch panel (PCAP), to its OLED portfolio. The active area is 30.0 mm (1.18″) in diameter, and this size makes it suitable for applications operated by rotation or touch, such as coffee machines, audiovisual equipment or smart home devices.
Thanks to a rotary switch and a capacitive touch panel, Raystar’s OLED module is easy to use.
The OLED module uses the SSD1327, a single-chip CMOS OLED/PLED driver with controller, specifically for organic/polymer light-emitting diode dot-matrix graphics display systems, which supports 4-pin SPI and I2C interfaces.
Equipped with a surface hardness of 6H (Mohs hardness scale), the PCAP touch panel acts through the IT7259, a controller with 24/13-channel capacitance sensors that supports both I2C interface and 1-point touch.
The resolution is 128×128 pixels. With white, yellow and sky blue, there are three luminous colors to choose. It also has 4-bit grayscale, which allows 16 shades of gray that can inform about different intensities, for example.
Other specifications:
- Module dimension: Ø56 × 21.56 mm
- Pixel size: 0.210 × 0.210 mm
- Pixel pitch: 0.235 × 0.235 mm
- Display Mode: Passive Matrix
- Duty: 1/128 Duty
