摘要： A display system provides automatic and manual brightness control. A brightness controller varies the luminance of the display based upon ambient light as sensed by an ambient light sensor. The brightness control varies the luminance of the display between the minimum luminance at a minimum illuminance to a maximum luminance at a maximum illuminance. Preferably, a user input device selectively varies the maximum illuminance at which the display displays said maximum luminance and selectively alters the minimum luminance which is displayed at the minimum illuminance.

摘要： A rush current preventing circuit for a liquid crystal display that is suitable for eliminating a rush current at the time of applying an initial power to the liquid crystal display includes an output enable signal generator generating an output enable signal to control outputs of the gate drive integrated circuits. A start output enable signal generator generates a start output enable signal having at least a desired interval of disable pulse at the time of applying an initial power. An output enable signal switching device switches the output enable signal and the start output enable signal in accordance with the start output enable signal.

摘要： A display system generally comprises an ELD including a plurality of pixels each activated by a voltage across an inner and outer electrode. A controller applies voltages to each of the pixels via the inner and outer electrodes at a refresh rate to illuminate the pixels. The controller varies the voltage and refresh rates of each of the plurality of pixels in order to provide varying levels of brightnesses of the pixels.

摘要： When a forward bias is applied between a selected unit electrode of scanning electrodes and a selected unit electrode of data electrodes to cause a selected pixel concerning both of the selected unit electrodes to emit light, and a reverse bias is applied between nonselected unit electrodes of the scanning electrodes and nonselected unit electrodes of the data electrodes, thereby preventing crosstalk caused by a semi-excited state of the nonselected pixels, all of the scanning electrodes and all of the data electrodes are short-circuited once, immediately before a predetermined unit electrode of the data electrode, which should be selected in accordance with selection of each of the unit electrodes of the scanning electrodes, is selected, to set all of the pixels at a zero bias.

摘要： An AMEL display is formed and operated in a manner to provide enhanced gray scale or color operation. The AMEL display is operated over consecutive illumination frames which are partitioned into a plurality of passes. The desired illumination intensity for a given pixel during each illumination frame is determined and the pixel is activated for a substantially equal duration in each pass to provide the desired illumination level for each frame. Each pass has an associated illumination profile signal composed of a plurality of discrete steps for selectively passing a number of illumination pulses to each active EL cell in the display in accordance with a pixel activation voltage loaded into each active EL cell. The pixel activation voltage and illumination profiles cooperate to distribute the number of illumination pulses in a substantially equal fashion in each pass of an illumination frame. Pixel driver circuits are disclosed for operating the pixel in accordance with the disclosed illumination methods.
