Abstract
A flexible circuit board mounted with top-light LEDs and LED control circuits provides a convenient and space efficient way to backlight an LCD. The flexible circuit board may have multiple tabs that are folded such that the top-light LEDs provide light into a light pipe from multiple directions. The top-light LEDs and LED control circuits may be located on the same side of the flexible circuit board for improved cost savings and manufacturability.
