AMOLED microdisplays continue to show improvement in resolution and optical performance, enhancing their appeal
for a broad range of near-eye applications such as night vision, simulation and training, situational awareness,
augmented reality, medical imaging, and mobile video entertainment and gaming. eMagin's latest development of an
HDTV+ resolution technology integrates an OLED pixel of 3.2 × 9.6 microns in size on a 0.18 micron CMOS backplane
to deliver significant new functionality as well as the capability to implement a 1920×1200 microdisplay in a 0.86"
diagonal area. In addition to the conventional matrix addressing circuitry, the HDTV+ display includes a very lowpower,
low-voltage-differential-signaling (LVDS) serialized interface to minimize cable and connector size as well as
electromagnetic emissions (EMI), an on-chip set of look-up-tables for digital gamma correction, and a novel pulsewidth-
modulation (PWM) scheme that together with the standard analog control provides a total dimming range of
0.05cd/m2 to 2000cd/m2 in the monochrome version. The PWM function also enables an impulse drive mode of
operation that significantly reduces motion artifacts in high speed scene changes. An internal 10-bit DAC ensures that a
full 256 gamma-corrected gray levels are available across the entire dimming range, resulting in a measured dynamic
range exceeding 20-bits. This device has been successfully tested for operation at frame rates ranging from 30Hz up to
85Hz. This paper describes the operational features and detailed optical and electrical test results for the new AMOLED
WUXGA resolution microdisplay.
