摘要： An apparatus for driving a light-emitting display controls the light-emission of light-emitting elements in such a manner that a driving current or driving voltage having a prescribed value to be supplied to the light-emitting elements is turned on or off by an on/off signal from a driving unit. The driving apparatus includes a pixel read section for reading the luminance values for the light-emitting elements in a frame period from an image signal and a &Dgr;&Sgr; modulator which operates in a sub-frame period which is 1/n of the frame period according to the luminance values read by the pixel read section. The output of “1” or “0” from &Dgr;&Sgr; modulator is served as the on/off signal. The driving apparatus can further includes a random data generator for providing random luminance values for the individual pixels. In an image displaying operation, the output from the random data generator is directly supplied to the &Dgr;&Sgr; modulator in place of the output from the pixel read section, or otherwise added to the output from the pixel read section. This configuration provides an image with good quality and naturalness in the luminance by the driving at low speed.

摘要： The disclosure concerns a light display panel with a matrix of pixels each comprising three monochrome electroluminescent diodes of three colors. The diodes are controlled by a control circuit delivering electrical power P to each diode, said electrical power being expressed in the form P−k.Pr, wherein Pr is a reference electrical power particular to the diodes of each color and k is a coefficient selected according to the display to be presented. Over the course of time the reference electrical power is subjected to different variations depending on the colors, to compensate for the aging of the diodes.

摘要： A light emitting display device having a plurality of light emitting elements connected to intersecting points of a plurality of anode lines and cathode lines arranged in a matrix. Either one of the anode lines and the cathode lines are used as scanning lines, and the others are used as driving lines. While one of the scanning lines is scanned during a scanning period, a driving source is synchronously connected to one of the driving lines so that a light emitting element connected to an intersecting point of the one scanning line and the one driving line is caused to emit light. Immediately after the scanning period of the one scanning line is started, a first driving source is connected to the one driving line, and subsequently, in exchange for the first driving source, a second driving source is connected to the one driving line.

The unique placement of the current sensing circuit within the boosting circuitry eliminates the need for a separate current regulating circuit, thus minimizing the circuitry needed to provide a constant back lighting LED array of constant luminosity.

摘要： In a first aspect of the invention, a driven element is driven by a static driving element coupled in series with a switching element. The static driving element sets the driving current value. In a second aspect, a plurality of driven elements are driven by respective driving elements, which in turn are driven by respective pre-stage circuits, using a control voltage supplied by a single control-voltage generating circuit. Resistors inserted between the driving elements and pre-stage circuits limit transient current flow to a value within the output capability of the control-voltage generating circuit. In a third aspect, the pre-stage circuits have constant-current output characteristics, and the control-voltage generating circuit is designed to provide the necessary transient current, even when all driven elements are driven simultaneously.
