Transparent OLED Display Module

The module is an elegant combination of a fully transparent PMTOLED Passive Matrix Screen, along with a modest but comprehensive collection of I/O features, including a micro-SD card connector, two general purpose input/output pins (GPIOs) with Dallas 1-Wire Support, Analog Input, and sound generation capability, along with serial communications. Combining a resolution of 128x160 pixels with 65K colours, this display module is a perfect solution for any application requiring a transparent display with a brilliance of color, animation, or images.

Embedded at the heart of the design is the GOLDELOX processor, which is driven by a highly optimised virtual core engine called EVE (Extensible Virtual Engine). Powerful graphics, text, image, animation, and countless more features are built inside the GOLDELOX chip. The GOLDELOX processor is a very capable chip which provides impressive graphics power, programmed with 4D Systems Workshop IDE Software. 4D Systems Workshop enables graphic solutions to be constructed rapidly and with ease due to its design being solely for 4D's graphics controllers. The microOLED module can be programmed in its native 4DGL language, a graphics oriented language allowing the developer to write applications in a high level language, syntax similar to popular languages such as BASIC, C, and Pascal.
