  • Publication number: 20170156191
    Abstract: A system to compensate for luminance degradation of an emissive display is provided. The system employs a combination of a consumption rate limit and temperature to regulate and control display luminance for emissive displays (such as organic light emitting diodes). A consumption rate limit is employed to determine a display luminance ceiling at which to drive the display. By employing the aspects disclosed herein, the display systems may achieve a longer lifetime.

  • Patent number: 6961051
    Abstract: A circuit assembly detects a touch point within a display area. A plurality of light emitters are disposed around a periphery of the display area. A plurality of detectors are disposed around the periphery, each detector being opposed to a respective light emitter. Switching circuitry for connecting the light emitters and detectors in a switching matrix has a plurality of matrix rows and matrix columns. The switching circuitry includes a plurality of row lines, each row line corresponding to a respective matrix row and a plurality of column lines, each column line corresponding to a respective matrix column. Low-side switching transistors selectably couple the light emitters and detectors to the row and column lines, respectively. A common modulated signal is coupled to the anodes of all the light emitters. A detection signal is provided by connecting the collector terminals for the detector phototransistors in common. Consequently, high-side multiplexing circuits are avoided.

  • Patent number: 6762741
    Abstract: This invention provides an automatic brightness control system for display devices, which may have a lighted display, a sensor, and control circuitry. The sensor logarithmically generates a first signal in response to the ambient light near the lighted display. The control circuit selects a display luminance from one or more luminance adjustment sequences having essentially constant ratio steps. The display luminance is a fractional power function of the ambient light near the display. The fractional power function may be adjusted by a constant luminance ratio offset.

  • Patent number: 6690121
    Abstract: A lamp brightness control for a lamp provides backlight illumination for a display. A brightness-to-current translator generates an electrical current command having a magnitude proportional to a desired lamp current that corresponds to a desired brightness. A PWM generator generates a PWM drive signal having a duty cycle determined in response to a control signal. A lamp driver switches power to the lamp in response to the PWM drive signal. A current sensor generates a current feedback signal in response to a flow of current in the lamp. An error amplifier generates the control signal in response to the electrical current command and the current feedback signal, whereby an actual lamp current is substantially equal to the desired lamp current despite any temperature offsets in the PWM generator or the lamp driver, for example.

  • Patent number: 6670781
    Abstract: A flicker reduction method for a lamp assembly includes providing current pulses to a fluorescent lamp in response to a periodic signal such as a ramp voltage. The current pulses illuminate the fluorescent lamp. The method further includes providing at least a predetermined number of current pulses to the fluorescent lamp per period of the periodic signal. A feedback circuit samples current in the fluorescent lamp to ensure that a predetermined number of current pulses have been provided. After the pulses are provided, the circuit is reset for the next cycle of the periodic signal.

  • Patent number: 6563479
    Abstract: This invention provides a resolution control system for a display device, which may have a lighted display and control circuitry. The lighted display may be backlit, frontlit, or emissive. The resolution control system may have two or more digital-to-analog converters, which may be provided by digital-to-analog converter (DAC) circuitry in the control circuitry. The DACs convert data values into an output voltage for controlling an operating parameter, which may be brightness, contrast, and the like. The DACs have a cascade arrangement where the output voltage of one DAC is the input voltage of another DAC.
