Embodiment Construction

[0021] In order to illustrate a preferred embodiment of a driving system for an electroluminescent display and a method for implementing display driving, a display panel having a matrix of display elements of 64 rows by 132 columns is taken as an example in the following description. In this matrix, the anodes of the display elements are connected to the anode line A 1 -A 132 , while its cathode is connected to the cathode line B 1 -B 64 . It should be noted that this connection is not a limiting connection of the present invention. For illustrative purposes only, the drive system described here has a connection structure assuming that the cathodes of the electroluminescent elements are connected to the row scan lines, and the anodes are connected to the column drive lines. In general, if equivalent changes are applied on a similar basis, this drive system can also be applied to other panel configurations in which the polarity of the electrodes of the components and the al...

Abstract

A driving system and method used in the electrolumescent display is to reduce the desire of the switch current of the system power based on the principle of charge storage and recirculation. In the electroluminescent display having multi-electroluminescent units arranged in two-dimentional matrix, the positive of the said units in each array is connected to a corresponding positive line while thenegative of said unit is connected to a corresponding negative line. A driving system used to drive the electroluminescent display with an array of controlling circuit while in a driving scheme, it illuminates at least on of said illuminating unit by setting up a circuit route between the power and the earth. Said scheme is to scan each positive line in sequence and drive at lease one negative line during each scanning.

Description

technical field [0001] The present invention relates generally to electroluminescent displays and, more particularly, to drive systems for electroluminescent displays and methods of operating such systems with lower operating requirements and higher response rate performance. Background technique [0002] A typical electroluminescent display (ELD) is a device based on electroluminescent elements arranged in a two-dimensional matrix of rows and columns. Typically, each electroluminescent element in a display has two electrodes of opposite polarity, ie, an anode and a cathode. One of the electrodes is connected to a row line and the other electrode is connected to a column line of the driving circuit of the system. Each electroluminescent element in the matrix is ​​located where the address row and column lines for that particular element intersect. [0003] An electroluminescent element emits light when it conducts an electric current. The phenomenon of luminescence can be...
