Rugged Notebooks and Tablets - the challenge with display viewability

Rugged notebooks and tablets are designed to withstand the challenges associated with harsh and unpredictable environments. Optimized for mobile workforces whose jobs take them out of the office, on the road, and even into battle, these devices connect users with their networks and applications. The primary downside to these devices is that the slightest amount of sunlight reflection, touch-screen, or non-office lighting conditions creates challenges that wash out the display rendering the image almost unreadable.

Technology Approaches to Improving Display Viewability

Recent improvements in display technology have taken small steps to overcome this limitation. The approach used by most manufacturers has been more "brute force" than sophisticated design. The industry's 'brute force' method calls for simply increasing the display brightness (measured in NITs. By adding additional backlights NIT ratings quickly increased from 250 to 500 - and now to an eye-squinting 1,000 NITs.

Displays that incorporate multiple backlights to generate adequate light (1,000 NITs) to overpower direct sunlight are not the ideal solution one might think. While this is an improvement to standard technology the implementation has numerous weaknesses and customer trade offs which need to be considered before selecting a device for mobile workforces.

► Battery life suffers as more power is required to illuminate the display. To compensate for poor battery

performance, some companies use low voltage or ultra low voltage processors which significantly reduce

processor performance,
or,

they will reduce the bright-ness by over 50% when the unit is undocked.

► Contrast ratio and colour saturation remain low in direct sunlight making it difficult to distinguish fine details such

as text and map details.

► The extra light (NITs) overpowers the LCD pixels causing dark colours to appear grey and the image to become

washed out.

► CCFL backlights dim over time (25% in the first year). The more backlights you have, the more the overall

brightness degrades over time.
