Is this OLED screen sharp enough to replace an optical viewfinder?

The 5.4 megapixel microdisplay from MicroOLED measures just 0.61-inches diagonal, yet provides S-XGA resolution in full color — at half the power consumption of competing products the company claims.

“The current trend in replacing optics with electronics components fits excellently with our ability to produce this exceptional picture quality in miniature format,” MicroOLED says. “We are really excited by the market potential.”

The Organic Light-Emitting Display is ideal for applications demanding high picture quality, the French firm says, “sharp images with very smooth transitional tones” such as professional camera and camcorder equipment, night vision systems and head-mounted displays used in surgery.

The ultra-compact microdisplay has a 2,560 by 2,048 pixels resolution, and a sub-pixel pitch of 4.7 by 4.7 micrometers — the highest pixel density OLED microdisplay available today, the company claims. “By doubling the pixel density of comparable products, MicroOLED has eliminated the gap between pixels. With no black matrix present, the resulting image resolution is of the highest quality.” The maximum contrast of 100,000:1 and 96 percent uniformity also play key roles in picture quality, it adds.

Founded in 2007, MicroOLED is a privately held company with headquarters, R&D and a new production facility located in Grenoble, France.
