This letter proposes a novel active-matrix (AM) micro light-emitting diode (micro-LED) display architecture featuring fingerprint detection. A new pixel circuit comprising four transistors and one capacitor (4T1C) is proposed to compensate for threshold voltages externally. The AM micro-LED does not need any additional light sources sensors because an LED itself can be used photosensors. 4T1C i...

Colour harmony plays an important role in fine arts, architecture and design. But it can be also important to describe the quality of light sources: the distortion of perceived colour harmony of a set of colour samples under a light source can be a relevant factor by ranking the perceived colour quality of different light sources. In an earlier experimental study[1], we came to the conclusion t...

We report on the development of a realistic dynamic simulation of oncoming headlamp glare in a driving simulator. To our knowledge, no such simulation had been attempted or achieved previously. The simulation is based on superposition of a bright LED display through a beam splitter on the simulator screen and synchronizing the illuminated LED position to the image of the simulated oncoming car....

In order to solve the problems of large rendering load and low frame rate caused by screen power system five-sided LED-CAVE immersive virtual simulation platform, article proposes a 1+N cluster synchronization for Display management system. Configure with high-performance graphics workstations synchronous display cards according size resolution each screen. Through 3D optical tracking positioni...
