    摘要： A color balancing circuit for a flat panel display such as an electroluminescent display generates a primary current that can be varied to adjust the overall brightness of the display. Three currents related to the primary current by selectable ratios are generated, by current mirror circuits, for example; the ratios can be individually varied to adjust the color balance. Driving currents are generated from the three adjusted currents, by mirroring the adjusted currents, for example, and are used to drive display elements that emit light in the three primary colors. Image brightness and color balance can accordingly be adjusted separately, even though both are adjusted by adjusting the driving current. Circuit size is reduced in that the same primary current is used for all three primary colors.

    摘要： A driving circuit drives a display panel having a matrix of picture elements and electrodes. The driving circuit includes a memory storing compensation data for compensating for position-dependent brightness differences between the picture elements. The brightness differences are due to the stray resistance and capacitance of the picture elements and electrodes. A correction circuit modifies image data according to the compensation data to generate control signals, which are used to control drivers that drive the picture elements via the electrodes. The modified image data produce a display with an even average brightness over the entire display panel.

    摘要： A display panel driver has two driver circuits that drive separate halves of a display panel. Each driver circuit occupies a separate integrated circuit chip. The driver has a screen saving mode in which each driver circuit displays an independent screen saving image that moves in synchronization with a timing signal. The timing signal is generated in one driver circuit and transmitted by a chip-to-chip interface to the other driver circuit. The two screen saving images are thereby coordinated to create what appears to be a single screen saving display.
