OLED full-colour microdisplay; image quality and sharpness – in distribution

April 22, 2016 // By Graham Prophet
Specialist distributor Astute Electronics has the MicroOled MDP02 full-colour 1.56 cm (0.61 in.) microdisplay, that uses a unique pixel design to improve colour reproduction.

The 5.4 million dot OLED microdisplay was designed using MicroOled’s low voltage technology. The pixel design comprises four sub-pixels and a large pixel aperture with no black matrix to provide ultra high contrast and excellent image quality and sharpness. The cutting-edge RGBW sub-pixel structure enables the reproduction of colours and shades in greater detail, from shadow to highlights.


Brightness is up to 400 cd/m ². The additional white sub pixel makes the display brighter and more power efficient. There are no contrast or colour changes as the viewing angle changes, thus there is a consistent image even with wide field-of-view optics. Long-range uniformity is better than 96% and pixel-to-pixel uniformity gives homogenous smooth images. The OLED technology also enables sharp images of fast moving objects due to response times of less than 1 msec. The product integrates an individually calibrated look-up table ensuring uniform high image quality in terms of luminance, white point, gamma characteristics and colour reproduction.


Typical applications would be displaying information for head-mounted displays, thermal and digital night vision devices, and electronic viewfinders requiring excellent colour reproduction. They can be connected to a large range of image sensors such as micro-bolometers, low-light digital image sensors, CCD sensors and CMOS sensors.


Specifications include 1300 x 1044 resolution, 9.4 by 9.4 µm pixel size, 12.22 by 9.81 mm active area, 100,000:1 contrast, 25 to 60 frames per second, I ²C interface, 250 mW power consumption in video mode, and -20 to +50˚C or -40 to +70˚C operating temperature.
