Title:
発光ディスプレイのための回路および制御方法
Document Type and Number:
Japanese Patent JP2007536585
Kind Code:
A
Abstract:
A circuit for an element of a light-emitting display is proposed. The element comprises a current control means, first and second switching means and a light-emitting means. In one embodiment, a signal holding means is provided. The arrangement of the first and second switching means of the element makes it possible to measure the electrical parameters of the current control means and of the light-emitting means during operation. A light-emitting display having a plurality of elements is furthermore proposed. The light-emitting display has a control circuit and a memory. The measured values of the electrical parameters of the current control means (4) and of the light-emitting means of the elements are used to correct the control signal S that is used to drive the elements. This enables a uniform brightness distribution in the case of voltage actuation and makes it possible to compensate for temporal changes in the light-emitting means. In addition, a method for actuating the elements and the light-emitting display is proposed.
