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
  • 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
  • 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
