Computers and laptops are increasingly used at work and at home. As a consequence, the exposure of short wavelength blue light, which is emitted by LED displays, increases too. By its action, light is well-known to enact damage on the neurosensory retina, especially on the underlying structures. In particular, this happens through photothermal, photomechanical, and photochemical mechanisms. Thi...

This paper explains the project which is a special kind of circular rotating 8 LED display. With the help some mechanical assembly, LED count, hardware requirement, and hence overall cost is cut to very affordable price and power is also saved. Also, maintenance and repairing of the display is so easy, that anyone having a little electronics knowledge can take care of this. All the synchronizin...

This position paper argues that more research is needed into identifying key abstractions and reference criteria for multi-purpose display systems. This would enable research in this area to go beyond the development of specific applications and move towards enabling infrastructures that could serve the needs of multiple applications.

Common projection optics use Köhler illumination to achieve a required lighting. These systems always prevent the realization of a compact optical configuration along with a high lumen output. Based on conventional Köhler illumination, a modified Köhler illumination system for LED-based projection display is presented in this paper, which can significantly reduce the system volume while allowin...

The flexible GaN-based light emitting diode (LED) has been fabricated on a plastic substrate for flexible display applications. The epitaxial structures of the GaN LED arrays are transferred onto a flexible substrate using standard soft lithography technology and connected to a source-meter by metal lines. To verify the mechanically and optically stable characteristics of the GaN LEDs on the fl...

In this Paper a micro display for an intraocular vision aid (IOVA) projecting an image of the environment onto the retina is presented. The display comprises an image of an array made out of single LED pixels. It is connected to a CMOS driver circuit using flip-chip technique. Since micro lenses have to be integrated into the substrate material for proper image projection onto the retina the ge...

The paper describes the development and application of several techniques for knowledge extraction from trained ANN models, such as the identification of redundant inputs and hidden neurons, deriving of causal relationships between inputs and outputs, and analysis of the hidden neuron behavior in classification ANN. Example of the application of these techniques is given of the faulty LED displ...

GaN micro-LEDs have been spotlighted as promising candidates for high-speed optical communication, which may become important components in 6G communication blueprint. To achieve a superior network covering sea, land and air we demonstrated cross-medium based on an 80 <tex-math notation="La...
