OLED vs LCD in Video Glasses

OLED

THE SCIENCE
With OLED (organic light emitting diode), a stack of organic polymers, including both emissive and conductive layers, is deposited on a substrate containing a thin-film transistor (TFT) array. An electrical charge passing between the bottom electrodes and an additional transparent layer on the surface of the display stimulates the emissive organic layer, which in turn creates light.

STRENGTHS
Like LCD, OLED requires no backlight or projection lamp. But unlike most LCD 's we've seen to date, an OLED doesn't need to keep its pixel cells partially fired up at all times to be ready to respond to the signal. That's because OLED cells respond so quickly, they can be fully turned off until needed. Signal response time in an OLED is measured in microseconds (a far cry from the several millisecond response times in today's LCDs). Bottom line: Blacks on an OLED should be pretty much as black as black can be, which makes for a bright and dynamic picture with depth that has to be seen to be believed.

OLEDs also promise dramatically reduced power consumption, and much faster screen response times than LCD.

With a depth of only a few millimeters, OLED is one of the thinnest display technologys available - its ultra-slim form factor makes it akin to an architectural element like glass or mirror. Also, variations on the technology, such as transparent OLED, hold the promise of cool, futuristic augmented reality applications.

WEAKNESSES
Manufacturing OLEDs involves several patented technologies, which require costly license fees. This results in the technology being more expensive that LCD.

LCD is a mature technology. OLED technology has barely busted out of the lab. IN addition to Video Glasses OLED displays can be found in digital cameras, GPS units, and portable media players. Two reasons why OLED manufacturing lags behind LCD are low yield (only a small number of panels actually make it past the quality-control stage) and differential aging (the blue pixels in an OLED display tend to lose brightness at a faster rate than red and green ones, which means OLED displays may have a limited lifespan compared to LCD.

LCD

THE SCIENCE
A matrix of thin-film transistors applies voltage to liquid crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals "untwist" to filter light coming from behind the cells. Each pixel comprises a red, green, and blue cell.

STRENGTHS
Image quality is advancing rapidly among LCD manufacturers. Response time, color accuracy, picture uniformity (the ability to deliver consistent brightness and color across the screen), and horizontal viewing windows have (for the most part) improved notably in the latest generation of sets. But the biggest thing LCD may have going for it is that manufacturers are banking on it as the future of mass market television, and have invested mountains of cash in new automated plants that will drive volume up and prices down. This should also drive prices down for Video Glasses Displays.

WEAKNESSES

Many LCDs lose contrast when you're off-axis. Some screens are susceptible to motion blur and judder.
