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.

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 drive apparatus of a display panel is provided with an anode driver that drives m anode lines CL, a cathode driver that scans n cathode lines RL, and control means. In a process of pre-charging a parasitic capacity Cp of display elements connected to any of the scan lines RL whichever selected by the cathode driver, the control means switches a connection of L of the n scan lines RL and the m anode lines CL to a ground terminal, and applies voltage control with (L/n)×Vccr for application of an initial output voltage of the anode driver at about an EL element drive voltage Vf. In this manner, the parasitic capacity Cp of the EL elements connected to L scan lines RL is pre-charged. With such a drive apparatus of the display panel, without causing to be complicated in configuration, and without increasing the size of the circuit, it becomes possible to set and control a voltage for pre-charging a parasitic capacity of organic EL elements to be any needed voltage or current.
