In terms of module size, a VFD requires backlight, PCB, electronics and mechanical parts to be mounted around its frame. It also needs thick and strong sealing glasses to ensure vacuum encapsulation. All these contribute to the bulky construction and high production cost of a VFD. In contrast, the maximum thickness of an OLED display is just 1.3 mm as it is only made up of a single emissive layer which is sandwiched by two thin glasses. Since an OLED display requires fewer components to drive, customers’ BOM are significantly reduced.
Densitron’s 2×16 (DD-2C16WE-1A, DD-2C16YW-1A) and 2×20 (DD-2C20WE-1A, DD-2C20YW-1A) Character OLEDs are mechanically compatible with VFDs and are available in yellow and white. Red, blue and green colours can be customized. The displays come with in-built font CGROM, user-friendly connector boards that enable easy system integration and Chip-On-Glass configuration. The modules can be configured for 8 or 4 bit parallel/SPI/I2C interface.
USB Evaluation Kits are now available for the Character OLEDs. The displays can be further enhanced through Densitron’s Engineering Design Service which offers options on integrating standard or custom display modules with touch screens, PCBs, Plastics, and/or Keypads.
