| 20080231571 | Color Overdrive for Color Sequential Matrix-Type Display Devices - A method and apparatus for increasing the brightness of a color-sequential matrix display, in which the matrix display is addressed on a line-by-line basis, includes dividing a frame period of said matrix display into sub-fields corresponding to the number of light colors being used to sequentially illuminate said matrix display illuminating the display sequentially with said light colors, each for the duration of the corresponding sub-field, and pre-processing the video signal to compensate for errors due to illuminating the display during the addressing time and LC response time. The pre-processing includes determining a direction and an amount of gray scale level change from a preceding sub-field to a current sub-field, and increasing or decreasing the video signal in the current sub-field in dependence on the determined direction of the gray scale level change from the preceding sub-field and by an amount corresponding to a predetermined factor of said determined amount of gray scale level change. | 09-25-2008 |
| 20090091522 | DRIVING AN IN-PLANE PASSIVE MATRIX DISPLAY - A driving circuit for driving an in-plane moving particle device has a pixel (P) comprising movable charged particles (PA). The pixel (P) has a reservoir electrode (RE), a display electrode (DE), and a gate electrode (GE) laterally placed in-between the reservoir electrode (RE) and the display electrode (DE). The driving circuit (DC) comprises a driver (DR), a controller (CO) which receives an input signal (OS) representing an image to be displayed on the moving particle device. The controller (CO) controls the driver (DR) to supply a first voltage difference (VD | 04-09-2009 |
| 20100045205 | REMOTE COLOR CONTROL DEVICE AND LIGHTING SYSTEM - A device is disclosed for wireless control of color of light emitted by a lighting system. The lighting system comprises signal receiving means and means for adjusting the color of light emitted from at least one lighting element, in response to a received color control signal from the device. The device for wireless control comprises means for—generating color information data, said data being indicative of a desired color of light to be emitted by the lighting system, means for modulating a first carrier signal in accordance with the color information data, and means for transmitting said color control signal in the form of a beam of said first modulated carrier signal to the lighting system. | 02-25-2010 |
| 20100053135 | ELECTRONIC DEVICE USING MOVEMENT OF PARTICLES - A method is provided of driving an electronic device comprising an array of device elements, each device element comprising particles which are moved to control a device element state, and each device element comprising a collector electrode, and an output electrode. The method comprises: in a reset phase, applying a first set of control signals to control the device to move the particles to the a reset electrode; and in an addressing phase, applying a second set of control signals to control the device to move the particles from the reset electrode such that a desired number of particles are at the output electrode. The second set of control signals comprises a pulse waveform oscillating between first and second voltages in which the first voltage is for attracting the particles to the reset electrode and the second voltage is for attracting the particles from the reset electrode to the output electrode, and wherein the duty cycle of the pulse waveform determines the proportion of particles transferred to the output electrode in the addressing phase. This control method provides well-controlled packets of particles which are collected in a vortex at the reset electrode before being passed on, in part, towards the output electrode (for example via the gate electrode). | 03-04-2010 |
