The newly added displays have vivid colours, an operating temperature range from -20ºC to 60ºC, low power consumption and are available in sizes ranging from 2 to 4.3in, measuring between 1.3mm and 2mm in thickness. AMOLED technology is based on a multi-layered organic film placed between an anode and cathode on an array of Thin Film Transistors (TFT). By applying an electrical pulse to each transistor in the array, individual pixels will be illuminated.
Compared with traditional backlit transmissive technologies, AMOLEDs consume considerably less power as it is an emissive technology and each of its pixels emits its own light and consumes no power at all when not illuminated. The exact power consumption of an AMOLED display will vary according to the image displayed but it consumes between 25% and 60% less power than that of a panel which employs a conventional display technology, such as TFTs.
Apart from the size and power consumption advantages, an AMOLED display also offers a high contrast ratio (readable in sunlight), a response time of only a few micro seconds and an Unlimited Viewing Angle, making it suitable for many applications including those involving video play-back.
Besides, the new displays come with serial, digital RGB (18 or 24 bit) and MPU interface options with 262K or 16 million colours, and up to WQVGA resolution depending on the panel, this makes them suitable for applications where small TFTs are used.
Densitron’s Product Manager Elijah Ebo states, “Densitron is delighted to provide complimentary Technical Support Assurance on its range of CMEL AMOLED displays. We also offer a series of easy-to-use USB based evaluation kits that facilitate software prototyping and the sampling of the new technology.”
“It is very exciting for Densitron to add this complementary range of AMOLED displays to our extensive solutions. We are very pleased to be working closely with a major partner like CMEL,” comments Densitron Displays’ Managing Director Grahame Falconer.
