20120001570 | METHOD OF CONTROLLING AN LED, AND AN LED CONTROLLER - 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 whilst 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 utilise 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. | 01-05-2012 |

The effective dielectric constant of the aperture and/or the dielectric constant of the substrate is varied, thereby to vary the light transmission characteristics of the pixel between transmission of at least one frequency in the visible spectrum and transmission of substantially no frequency in the visible spectrum. | 05-03-2012 |
