Method and system for driving a light emitting device display

Abstract

A method and system for driving a light emitting device display is provided. The system provides a timing schedule which increases accuracy in the display. The system may provide the timing schedule by which an operation cycle is implemented consecutively in a group of rows. The system may provide the timing schedule by which an aging factor is used for a plurality of frames.

Description

technical field [0001] The present invention relates to display technology, in particular to methods and systems for driving light emitting device displays. Background technique [0002] Active-matrix organic light-emitting diodes (AMOLEDs) utilizing amorphous silicon (a-Si), polysilicon, organic or other drive backplanes have recently been developed due to their advantages over active liquid crystal displays. become more attractive. AMOLED displays utilizing a-Si backplanes have, for example, advantages including low temperature fabrication that expands the utilization of different substrates and enables flexible displays, reducing manufacturing costs. In addition, OLEDs produce high-resolution displays with wide viewing angles. [0003] An AMOLED display includes an array of rows and columns of pixels, each with organic light emitting diodes (OLEDs) and backplane electronics arranged in the row and column array. Because OLED is a current-driven device, the pixel circuit...

Problems solved by technology

[0006] However, since V T The generation cycle "VT-GEN" requires a large time budget to generate accurate threshold voltages for driving TFTs, so this timing schedule cannot be used for large area displays

Furthermore, performing two additional duty cycles (i.e. "C" and "VT-GEN") results in high power consumption and also requires additional control signals resulting in higher implementation costs
