    Abstract: An the LED driving circuit, for driving an the LED load, includes: a bridge rectifier for rectifying an AC input voltage into a DC voltage; a serial capacitor voltage divider coupled to the bridge rectifier, including a plurality of serial capacitors; a half-bridge switch, coupled to the serial capacitor voltage divider; and a controller coupled to the half-bridge switch, for determining whether the DC voltage is higher than a threshold value and for controlling the half-bridge switch in a full-voltage mode or a half-voltage mode. In the full-voltage mode, the plurality of serial capacitors of the serial capacitor voltage divider synchronously supply power to the LED load. In the half-voltage mode, the plurality of serial capacitors of the serial capacitor voltage divider alternatively supply power to the LED load.

    Abstract: The invention provides a method for patterning a flexible substrate. The method for patterning a flexible substrate includes providing a carrier substrate. A release layer is formed on the carrier substrate. A flexible substrate film is formed on the release layer. A plurality of UV blocking mask patterns is formed covering various portions of the flexible substrate film and the release layer. A UV lighting process is performed to expose the flexible substrate film and the release layer not covered by the UV blocking mask patterns, to a UV light. A debonding step is performed so that the various portions of the flexible substrate film directly above the various portions of the release layer, which were not exposed to the UV light, are separated from the carrier substrate.
