OLED-TV Display/Monitor Technology News

Because OLED structures emit their own light, they feature several appealing performance characteristics.
Lower power consumption. With no need for backlights and extra heaters or coolers, eMagin microdisplays consume much less power than other near-eye displays of similar size and resolution. This permits products using OLED displays to operate using only USB port power.

Higher contrast. OLED materials can support the full spectrum of visible light.

A broader color gamut. Typically, eMagin microdisplays deliver more than the standard 24 bits of color (16 million colors) at the same time at any point on the screen. LCDs usually display subsets or pallets of colors or delay-smear changes so a far smaller number of colors is available at any point in time.

High-speed refresh rates. eMagin microdisplays have no problem supporting refresh rates of 30, 50, 60, 70, and even 85 Hz; individual pixels refresh in nanoseconds and there is no flicker.

OLEDs are many times faster than LCDs and even faster than CRTs. Fast motion and rapid eye movement more life-like.

Larger viewing angle. For near-eye applications, the Lambertian characteristics of OLEDs provide greater accommodation for pupil movement and more comfortable viewing  without distortion.

Ease of view. The OLED microdisplays with appropriate optics uniquely permit virtual images that appear realistic and are easy to view for long periods of time.

No need for energy wasting and distorting polarizers. In near-eye applications, chromatic distortion through enlarging optics is reduced. The lack of requirement for polarizers makes obtaining great images with low cost molded optics more practical.

Low cost systems solutions. In general, an OEM using OLED-on-silicon microdisplays will not need to purchase and incorporate lighting assemblies, color converter related Applications Specific Integrated Circuits, or ASICs, or beam splitter lenses as is the case in liquid crystal microdisplays, which also require illumination. Many important display-related system functions can be incorporated into an OLED-on-silicon microdisplay, reducing the size and cost of the system. Non-polarized light from OLEDs permit lenses for many OLED-on-silicon applications that are made of a single piece of molded plastic, which reduces size, weight and assembly cost when compared to the multipiece lens systems used for other microdisplays. System cost relative to competitive products is thus reduced. Because OLED displays are power efficient, they typically require less power at the system level than other display technologies at a given display size and brightness.

Wide operating temperature range. OLEDs offer much less temperature sensitivity at both high and low temperatures than LCDs without requiring heaters or loss of contrast. They turn on instantly and can operate between -55 ºC and 130 ºC. This is an important characteristic for many portable products that may be used outdoors in many varying environmental conditions. It is especially important for military customers. Insensitivity to vibration, shock, and pressure are also important environmental control attributes. eMagin specifies a smaller temperature range on most consumer products to accommodate lower cost packaging.
