Abstract: A capacitor divider comprising a plurality of capacitors is used for driving liquid crystal displays. The use of capacitor dividers reduces power consumption, which would be desirable for portable devices. Power consumption is reduced in some embodiments where no static current would flow in the divider.

Abstract: A method and apparatus for gamut color remapping and compensation is provided. In one embodiment, the invention is a method. The method includes receiving input image data. The method further includes determining relationships between the input image data and known correction values. The method also includes interpolating corrections to the image data input based on the known correction values. The method further includes applying interpolated corrections to the input image data to produce normalized image data. In another embodiment, the invention is a method. The method includes measuring color distortion for a video component. The method also includes determining transforms for a set of known correction data points for the video component. The method further includes storing parameters of transforms for the set of known correction data points for the video component.

Abstract: An electronic fluorescent device (EFD) is used as the back light source for a black/white LCD. Where the EFD provides red, green and blue light, the LCD displays multi-color or full-color images. The EFD includes a number of cathodes disposed in a vacuum chamber, an anode, phosphor strips near the anode, and grid electrodes for controlling the timing of the light generation and sequential color addressing. The control system may be such that the transmission rate of the LCD is proportional to the amplitude of the input signal forming an analog system; the EFD then simply provides sequential red, green and blue light pulses of constant intensity. Alternatively, selected pixels of the LCD may be addressed digitally to be either on or off, and the intensities of the red, green and blue pulses provided by the EFD are varied. In both instances, full scale gray tone monochromatic, multi-color or full-color images can be achieved.
