Evaluation of an organic light-emitting diode display for precise visual stimulation.

Evaluation of the Effect of Protective Sleeve on Output Intensity of Light Emitting Diode Light Cure Units

Aim: The purpose of this study was to compare the difference in the output intensity of Light Emitting Diode (LED) light cure (LC) devices with and without a protective sleeve and its clinical significance.  Materials and Methods: The output intensity of 152 LC units in dental offices across the state of Odisha were examined. The collection of related information included an average number of e...

Holographic head-mounted display with RGB light emitting diode light source.

A compact head-mounted holographic three-dimensional display with an RGB light-emitting diode (LED) light source is developed. Issues regarding full-color holographic image design and the quality associated with the use of an LED light source are investigated. The accommodation effect and background noise in the proposed system are discussed based on experimental observation.

White organic light-emitting diodes prepared by a fused organic solid solution method

This letter demonstrates a white organic light-emitting diode sOLEDd with high color stability fabricated by using a single organic white-emitting layer. The dopants were introduced prior to the device fabrication process through organic solid solution process formed by high-temperature and high-pressure fusion process. A high band gap organic material, a-naphthlyphenylbiphenyl diamine, was ado...

On the origin of high quality white light emission from a hybrid organic/ inorganic light emitting diode using azide functionalized polyfluorene†

Comparative evaluation of the effect of Light Emitting Diode (LED) and Quartz Tungsten Halogen (QTH) light curing units on color stability of Filtek Z350 XT

Introduction:Discoloration of the resin-based composites is a common problem in restorative dentistry. There are many factors associated with the discoloration of dental materials in the oral environment. The purpose of this study was to evaluate the color changes in a nano-composite cured with a quartz-tungsten-halogen (QTH) and light emitting diode (LED) unit. Methods:80 disk-shaped specim...
