LED BACKLIGHT, PASSIVE AND ACTIVE ENHANCEMENTS TO OEM BACKLIGHTS

After optimizing the optics to the front of the display, the next place to focus for improvement is the LCD backlight. Depending on your requirements and goals for your product this can be done through passive and/or active enhancements.

PASSIVE BACKLIGHT ENHANCEMENTS

Many LCD displays benefit from passive enhancements utilizing more efficient light diffusing films in the optical path by focusing the existing light emitted from the display to the optimal user eye position. Passive Enhancements alone nearly double the light output of many displays.

Two of our primary passive enhancements tools are 3M Vikuiti™ Brightness Enhancement Film (BEF) and Dual Brightness Enhancement Film (DBEF). The BEF materials works by focusing the light to the viewer and the DBEF film is a reflective polarizer which recycles the light that would otherwise be attenuated by the rear polarizer in the display.

We are amongst one of the largest consumers of 3M Vikuiti™ films in North America.

LED BACKLIGHTS AND ACTIVE ENHANCEMENTS

IDS can design and provide almost any commercially available display with an LED version. LED backlight provides increased brightness with less power, operate over a wide temperature range with no warm-up time (instant on in all conditions). Since LEDs are solid state devices, they are more robust in harsh environments.

Benefits of LED Backlights

  • Higher Brightness with less power consumption
  • Less heat to remove from the system
  • Wide Operating Temperatures – Instant On
  • Low Voltage operation for minimal impact on EMI/RFI
  • More robust when subject to mechanical shock and vibration
  • NVIS compatible LEDs for dual mode operation
  • Can be used in direct backlighting application to increase dynamic contrast
  • Long Life Operation and Redundancy
  • No Mercury and ROHS Compliant
