Longest battery life
The eyescreen® has ultra-low power consumption, enabling the longest possible battery life for portable video glasses. Its emissive P-OLED technology eliminates the need for a power-hungry back-light and its digital interface and fully digital signal pathway are much more energy efficient than the digital to analogue conversions required with other displays. Typically, the eyescreen® dissipates about a quarter of the power of traditional LCD microdisplays.

Superb moving video images
The full colour eyescreen® has superb moving video images that are free from the distracting flicker and blurring that is often seen with other microdisplays. High switching speeds and persistence of less than a microsecond allow the blur free images, whilst video frame rates of 50 – 120 frames per second eliminate flicker. Vivid pictures, due to the high contrast ratio, and image smoothness with no visible pixelation or ‘chicken wire’ effect, due to the high fill factor are all key features of the P-OLED eyescreen® microdisplay.

Smaller, lighter-weight designs
The highly integrated design of the eyescreen® with display drivers built into the silicon microdisplay chip, eliminates the need for additional driver IC components. This feature together with the emissive P-OLED technology of the eyescreen® which eliminates the requirement for a backlight saves space, power and cost of additional components for product design engineers enabling them to create the stylish, lighter-weight, lower power consuming products of the future.

Fast, robust design-in
Straight-forward, glue-less integration is possible using the eyescreen®. The BT.656 and serial RGB digital video interfaces enable a completely digital signal path and allow product design engineers to focus effort solely on software development. This digital signal path removes the requirement for a power-hungry analogue to digital conversion and eliminates loss in the dynamic range of composite video signals that is associated with analogue to digital conversions.

Enabling Wireless
Developing the first wireless video head-set will be a critical step in the mobile TV revolution. The digital interface and digital display driver ICs of the eyescreen® make it an excellent match for wireless technology and this together with its ultra-low power consumption, which greatly extends battery life, will make ‘eyescreen® enabled’ wireless head-sets as ubiquitous as the ball point pen.

Scaleable technology
P-OLED technology is at an early stage in its development life-cycle. Innovations in technology and processes will lead to rapid improvements in performance, unlike more mature LCD technology where changes have now become incremental. It will be straight-forward to scale-up the eyescreen® to higher pixel counts and wider aspect ratios and although QVGA (4:3 aspect ratio) is currently the standard resolution for video glasses for TV on mobile and personal media players, extension of the eyescreen® range to include WQVGA (widescreen 16:9 aspect ratio) and VGA are planned to keep pace with advances in technology.
