  • Patent number: 8842141
    Abstract: A method of uniform distribution for increasing a display rate. For data to be displayed, dividing a complete effective output enable (OE) time that is greater than one serial shift cycle into several unit serial shift cycles and uniformly distributing the effective OE time for display. The method implements the uniform distribution of the display time to the maximum extent by using an OE signal under the condition that the whole display time remains unchanged, thereby increasing effective output number of the uniform distribution, uniformly maintaining a display effect and steadily improving a refresh rate effect, so as to effectively increase a display quality and avoid a significant loss of brightness.

  • Patent number: 8456104
    Abstract: A method and system provide for dynamic control of backlighting of a light-transmissive bezel of a display device. A color control signal is received and processed by a processor and control element of the display device to generate a backlighting control signal and transmit the backlighting control signal to the backlighting element of the display device. The backlighting element generates a backlighting color to illuminate the light-transmissive bezel in accordance with the received backlighting control signal; the backlighting control signal adaptively controls the type and the duration of the backlighting color as determined by the color control signal received by the processor and control element.

The input color has an input chromaticity (C1) and an input lightness (Z-*) together forming an input point (202) in a chromaticity-lightness plane. The reproduction color has a reproduction point (210) in the chromaticity-lightness plane, wherein an absolute difference between the input lightness and the output lightness is a decreasing function of at least the chromaticity. An absolute difference between the input chromaticity and the output chromaticity is an increasing function of at least the chromaticity.

  • Patent number: 7911541
    Abstract: A liquid crystal display device includes a four-color conversion circuit with no chromatic changes in which the chromaticity and luminance of input image data are maintained, a four-color conversion circuit with chromatic changes in which the chromaticity and luminance of input image data are not necessarily maintained, and a selector for switching between the outputs from the two conversion circuits according to a level detection signal from a level detection circuit that detects whether the level of input image data is equal to 100% white level or higher. Display data from the selector is supplied to a liquid crystal section that displays an image by four-color pixels of red, green, blue, and white. The image data conversion circuit controls the light emission quantity of a backlight (BL) as white color, and converts input image data so that the level of data displayed on the liquid crystal section becomes uniform.

  • Patent number: 6486923
    Abstract: A color picture display apparatus employs an array of light-emitting diodes or other light-emitting elements emitting different colors. A television signal is converted to monochromatic signals of the different colors. A color converter modifies the monochromatic signals, thereby changing the displayed hues to match the hues that would be displayed on a television screen, to compensate for ambient lighting conditions, or to achieve other desired effects. If each picture element has only a single light-emitting element, the modification preferably avoids unlit gaps in monochromatic areas of the displayed picture.

  • Patent number: 5489950
    Abstract: A red image light signal emitting array, a green image light signal emitting array and a blue image light signal emitting array are driven by separate drivers in accordance with one-line image data at a time. The light signals emitted from the arrays are processed by a light signal combining lens and then are incident to a scanning mirror. The scanning mirror vibrates within a specified range of scan angles at a specified frequency, and while the scanning mirror reciprocates once, one frame of two-dimensional image is formed on a projection surface. The scan angle of the scanning mirror is detected by a detector, and the detector sends a detection signal to a timing signal generating circuit. The timing signal generating circuit is stored with values specified for the respective drivers, and when the detector detects that the scan angle becomes one of the values, the timing signal generating circuit sends a timing signal to the corresponding driver.
