    摘要: A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

    摘要: The present invention relates to a manufacturing method of an integrated circuit (IC) comprising a substrate (10) comprising a pixelated element (12) and a light path (38) to the pixelated element (12). The IC comprises a first dielectric layer (14) covering the substrate (10) but not the pixilated element (12), a first metal layer (16) covering a part of the first dielectric layer (14), a second dielectric layer (18) covering a further part of first dielectric layer (14), a second metal layer (20) covering a part of the second dielectric layer (18) and extending over the pixelated element (12) and a part of the first metal layer (16), the first metal layer (16) and the second metal layer (20) forming an air-filled light path (38) to the pixelated element (12). The air-filled light path (38) is formed by creation of holes in the first dielectric layer (14) and the second dielectric layer (18), filling the holes with sacrificial materials, and removal of the sacrificial materials after deposition and patterning of the second metal layer (20). This yields an IC having a low-loss light path to the pixelated element (12). The light path may act as a color filter, e.g. a Fabry-Perot color filter.
