Variability of Electroluminescent Displays

Printed passive matrix addressed electrochromic displays

Flexible displays are attracting considerable attention as a visual interface for applications such as in electronic papers and paper electronics. Passive or active matrix addressing of individual pixels require display elements that include proper signal addressability, which is typically provided by non-linear device characteristics or by incorporating transistors into each pixel. Including s...

Subpixel Image Scaling for Color Matrix Displays

The perceived resolution of matrix displays increases when the relative position of the color subpixels is taken into account. ‘Subpixel rendering’ algorithms are being used to convert an input image to subpixel-corrected display images. This paper deals with the consequences of the subpixel structure, and the theoretical background of the resolution gain. We will show that this theory allows a...

Crosstalk and image uniformity in passive matrix polymer LED displays

Passive matrix displays based on polymer and organic light-emitting diodes suffer from crosstalk, when the emission of light from one pixel depends on the operation of another pixel. We use circuit simulation in order to explain the causes of crosstalk and to quantify the consequences. Thrs work analyzes how crosstalk arises from electrode resistance, pixel leakage current, and the location of ...

Crosstalk in passive matrix i polymer r LED displays

Passive matrix displays based on polymer and organic light-emitting diodes (LEDs) suffer from crosstalk, t lk, the emission of lightt from pixels i ls other t than those selected. This article explores the topic of crosstalk both with an approximate i ate but analytic ti model and by means of more exact circuit i simulation in order to explain the causes of crosstalk and to quantify the consequ...
