LUT-Based Compensation Model for OLED Degradation

posted on 2023-06-08, 06:36 authored by David Antonio-Torres, Paul F Lister, Paul NewburyPaul Newbury
A compensation model for blue OLED devices, which is based on an OLED degradation model derived from luminance measurements of OLED devices, has been developed; it reduces degradation effects by monitoring the activity of a set of subpixels and adjusting the driving conditions of the blue subpixels of the display accordingly. To evaluate its performance, the compensation model has been embedded in an OLED display controller model, where its implementation is based on a lookup table. Simulations show that even with a reduced number of monitored subpixels, degradation is effectively reduced. B)2005 Society for Information Display

Notes

Originality: Describes a significant step forward from previous work on system-level compensation of Organic Light Emitting Diodes (OLED). A software framework is introduced combining system-level modelling and a novel software interface enabling experimentation with different compensation models and pixel monitoring schemes for adjusting driving conditions for simulated displays. Rigour: To evaluate its performance, the compensation model has been embedded in an OLED display controller model. Simulations run using the framework show that even with a reduced number of monitored subpixels, degradation is effectively reduced, increasing the life of the display by a factor of 2, moving it into a range suitable for commercial use. Significance: High International industrial significance. Makes a new method of compensation for degradation effects possible opening new markets for OLEDs in electronic devices. This is particularly important in the implementation of small mobile device displays such as mobile phones. Impact: Discussion on potential of implementation in display controllers for portable devices with Philips Research Eindhoven. Research based on work with Phillips as part of a FP5 EU proposal. Outlet: The Journal of the Society for Information Display (SID) along with the SID International Symposium Digest of Technical Papers are the top publications in the area of Displays research, with the journal being considered the standard for top international level displays research. Of a similar academic standing to the IEEE Journal of Display Technology they have been established much longer and have a significant industrial research track record. The SID has been in existence since 1962. Citations: Two Google Scholar citations
