White LEDs used in backlighting provide illumination for the pixels in liquid crystal displays. The LEDs are typically routed on one or two sides of the displays light diffuser, and biased with 20 mA ...
Malvern, Penna.—Vishay Intertechnology's two new white LED drivers, the SiP12401 boost controller and SiP12501 boost converter, are optimized for backlighting small liquid crystal displays in ...
When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...
Illuminating more than one very bright white LED requires a choice of configuration, either series or parallel. Of course, each configuration has design tradeoffs. A parallel connection requires a ...
Here is an excellent resource, certainly worth bookmarking if you are creating your own LED lighting systems - the LED series/parallel array wizard. It describes itself: The LED series/parallel array ...
Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...
Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
