Apple Files Patent On LED Backlight Technique

Apple certainly is putting a lot of thought into display technology, and if the company continues to come up with interesting products like the iPhone and iPad, having a great display will certainly be essential. The latest patent is titled “LED Backlight Driver Synchronization and Power Reduction”, which was filed just a short while after Apple unveiled its LED-backlit iPad. Apple’s patent looks to use a plurality of LED strings, rather than a single LED string, allowing them to be driven at a higher frequency than that of the LCD refresh signal, avoiding unwanted visual effects like flickering, shimmering or banding on LED-backlit LCD screens. Shimmering is described as a sparkling effect that occurs when a moving dark object meets or intersects with a lighter one. A good example would be when tree leaves are blowing in the wind, the leaves may appear to artificially shimmer at the edges of the leaves.
