  • LED Backlights Done Right
    LED backlights offer numerous advantages over CCFL backlights. General Digital's serial-parallel design allows the display to be used in the event of LED failure.
  • LED Backlighting: From sidelines to center stage in under 30 years
    Continued advances in design and performance have allowed each new generation of LED backlighting technology to significantly grow the number of relevant applications.
  • Sunlight Readable NVIS-Compatible Displays Excel with LED Backlights
    When discussing display technology that has the capacity to be sunlight readable or night vision goggle compatible-or both-LED backlights invariably enter the picture. Here, we outline the finer points of these technologies and how this trinity works together, allowing General Digital to bring you
  • The Evolution of Switched Capacitor Backlight Drivers in Mobile Phones
    Today the majority of mobile phones use white LEDs to provide backlighting for the color display. Nearly every phone designer strives to drive the backlight with the most efficient, smallest size, and simplest solution available. Typically they decide to implement one of the two most common types
  • Connecting LEDs: Serial vs. Parallel
    When designing a handheld device with a color display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you consider the key parameters – efficiency, brightness matching, LED control and physical size
  • New PCT Compound for LED Reflector Resin
    Light-emitting diodes (LED), as a new light source, are being used more and more as display backlight and general lighting. Due to the increase of brightness and electrical current of LED packaging (PKG), there are demanding requirements of LED re ector resins on heat. and light stability. A high
  • Drive High Intensity White LEDs Efficiently Using the PIC16C781
    High intensity white LEDs are rapidly gaining popularity because of their high light output for relatively low input current. Applications include small flashlights, backlighting, night visibility strobes for pedestrians and bikers, just to mention a few. This Technical Brief dis-cusses how
  • Powering Organic LEDs
    . OLEDs function by placing a series of organic thin films between two conductors. This light emissive technology requires no backlight, so it offers a much simpler architecture than TFT or active matrix LCDs. It also offers a thinner profile, a key consideration in space-constrained portable systems
