摘要： Die Erfindung betrifft eine Anzeigevorrichtung mit einer Treiberschaltung und einem Flüssigkristall-Display mit mehreren Reihen R und Spalten C. Desweiteren betrifft die Erfindung eine Treiberschaltung zur Ansteuerung eines Displays. Um den Stromverbrauch von Anzeigevorrichtungen zu reduzieren werden Displays im Partial-Anzeigemodus betrieben. Bei der MRA-Technik (Multiple- row-addressing) werden mehrere Reihen p gleichzeitig angesteuert. Die Anzahl der gleichzeitig anzusteuernden Reihen p ist aber für unterschiedlich große Displays unterschiedlich. Bei Betrieb eines Display im Partial-Anzeigemodus ist deshalb ein anderer Wert p für die gleichzeitig anzusteuernden reihen notwendig, als im Fullsize Betrieb, um eine optimale optische Performance zu erreichen. Zur Ansteuerung der Reihen R und Spalten C sind wenigstens p+1 Spannungen notwendig wenn F =G MAX . Da beim Übergang vom Fullsizebetreib zum Partial Anzeige-Modus die Anzahl der gleichzeitig angesteuerten Reihen reduziert wird, ist es auch nicht mehr erforderlich so viele Spannungen zu erzeugen, wie für den Betrieb im Fullsizemodus erforderlich waren. Deshalb wird über eine Schaltvorrichtung beim Übergang zum Partial Anzeige-Modus die nicht mehr benötigten Spannungstreiberstufen abgeschaltet. Dadurch können mit einer Treiberschaltung auch unterschiedlich große Displays angesteuert werden.

摘要： Systems and methods for realizing display drivers, especially OLED drivers having a high efficiency, are disclosed. With a single pass, using an algorithm based on simple equations based on gathered maximum display data, the driver (30) can split an image to be displayed into multiple planes and tiles thus balancing peak current consumption. Furthermore the driver is able to optimize drive time periods in regard of many parameters.

摘要： A passive matrix, electro-luminescent display system has a passive matrix, electro-luminescent display having an orthogonally oriented array of column and row electrodes and an electro-luminescent layer located between the electrodes at the intersection of each column and row electrode forming an individual light-emitting element. Drivers provide separate signals at different times to different groups of row electrodes within the array of row electrodes; wherein the row electrodes of each group simultaneously receive at least two different level signals. A display driver receives and processes the input image signal to provide a presharpened image control signal. Column drivers respond to the presharpened image control signal for simultaneously providing a signal to the multiple column electrodes within the array of column electrodes at the same time signals are provided to the groups of row electrodes so that the concurrence of row and column signals causes individual light-emitting element to produce light.

摘要： In an active matrix electroluminescent display, a plurality of rows of pixels are illuminated, defining at least two bands (10) of rows separated by a non-illuminated band (12). The bands (10) of rows of pixels scroll in the column direction over time, and at most 75 % of the rows are illuminated at any point in time. This method is in essence a double bar scrolling method. By scrolling two bars, the required peak brightness is reduced as the effective overall duty cycle is increased. However, the period of illumination can still remain short, so that motion perception remains improved. The scrolling speed can be halved for the same frame rate or else the frame rate can be increased to reduce flicker.
摘要翻译：在有源矩阵电致发光显示器中，多行像素被照亮，限定由非照明带（12）分隔开的行的至少两个带（10）。像素行的条带（10）随着时间在列方向上滚动，并且在任何时间点最多有75％的行被照亮。这种方法本质上是一种双杠滚动方法。通过滚动两个条，随着有效整体占空比的增加，所需峰值亮度降低。然而，照明时间仍然很短，所以运动感觉仍然得到改善。在相同的帧速率下，滚动速度可以减半，否则帧速率可以增加以减少闪烁。
