Winstar provides Character OLED display and Graphic OLED modules. They offer COB/COG/TAB construction PMOLED.
PMOLED do not require any backlight and filtering systems.

PMOLED stands for Passive-Matrix OLED, which relates to the way you control the display. A PMOLED display uses a simple control scheme in which you control each row (or line) in the display sequentially (one at a time).
PMOLED electronics do not contain a storage capacitor and so the pixels in each line are actually off most of the time. To compensate for this you need to use more voltage to make them brighter.

PMOLED displays are restricted in resolution and size. PMOLED displays are usually small (up to 3" typically) and used to display character data or small icons: they are being used in wearable devices, small gadgets and sub displays.

Winstar has formfit replaceable PMOLED displays in her portfolio, to exchange existing STN and FSTN designs.

PMOLED Displays are available in Yellow / Green / Red / White / Blue.

The uOLED-160-G2 compact intelligent display module from 4D Systems brings to life a breath-taking 1.7" PMOLED screen. Driven by the GOLDELOX graphics processor, this flexible embedded graphics solutions is the perfect compact display solution for any application requiring crisp and eye popping colours on a sharply refined screen.

Driven by a highly optimized virtual core engine the GOLDELOX chip integrates powerful graphics, text, image, animation and countless more features. The GOLDELOX is also powerful enough to control and communicate with peripheral devices over SPI, One Wire or Serial Port.

The uOLED-160-G2 offers modest but comprehensive I/O features that can interface to serial, analogue, digital, buttons, joystick, sound generation and Dallas 1-wire devices.

This display module can be programmed in its native 4DGL language (similar to C), using the Workshop 4 IDE Software tool suite. It can also be configured very easily as a serial slave device, for use with your favorite host controller.
