We offer a wide range of PLED alphanumeric modules. An OLED (Organic-Light-Emitting-Diode) is an light emitting diode whose emissive electroluminescent layer is composed of a film of organic compounds. The layer usually contains a polymer substance that allows suitable organic compounds to be deposited. They are deposited in rows and columns onto a flat carrier by a simple “printing” process. The resulting matrix of pixels (or custom segments) can emit light of different colors. As significant benefit of OLED displays over traditional liquid crystal displays is that OLEDs do not require a backlight. So the low power consumption is ideal for handheld products. In general there are basically two different technologies available. Small molecules displays often involves vacuum deposition, which makes the production process more expensive

Most of our modules operate within the wide temperature range (-20°C to +70°C) without negative voltage. A contrast-voltage of ~ 4,5 Volt is required (against Vdd). The twist of 240° results in excellent contrast and improved viewing cone. We use a 16pin version PCB with optional pins for the LED-backlight (A/K). Our modules have LED-limit-resistances already on board. These resistors can be changed or bridged easily. If neccessary, the power consumption and brightness can be optimized as per customer's request. The metal bezel is set on ground. If neccessary, our PCB is prepared for disconnection. In addition to our wide range of alphanumeric modules in standard STN technology, we have recently introduced
