A blind deconvolution algorithm based on the Richardson -Lucy deconvolution algorithm is presented. Its performance in the presence of noise is found to be superior to that of other blind deconvolution algorithms. Results are presented and compared with results obtained from implementation of a Weiner filter blind deconvolution algorithm. The algorithm is developed further to incorporate functional forms of the pointspread function with unknown parameters. In the presence of noise the point-spread function can be evaluated with 1.0% error, and the object can be reconstructed with a quality near that of the deconvolution process with a known point-spread function.
In this paper measurements on several types of active matrix polymer LED (AMPLED) displays will be presented. The issues of image uniformity and polymer aging will be addressed by pixel circuit designs.
A new optical feedback pixel circuit is presented that enables a high degree of differential ageing correction, has low power consumption compared to standard AMOLED pixel circuits and enables a high degree of non‐uniformity correction. The circuit operation and the technology used to construct it will be described and results presented.
Abstract— We have developed a new multi‐head polymer OLED ink‐jet‐printing technology to make large‐screen OLED television displays. This printer is used to make a 13‐in.‐diagonal 16:9‐format polymer‐OLED prototype driven by an LTPS active matrix with a pixel circuit which compensates for TFT threshold‐voltage variations. A novel scrolling‐bar addressing scheme is used to reduce motion artifacts and to make sparkling images with a high local peak brightness. The scalability of the polymer‐OLED technology to larger sizes for television applications is discussed.
