Reportedly, Apple's iPad 5 will be up to 33% lighter than its predecessor. The tablet is rumoured to be going into production in July ahead of a September launch, with the Cupertino firm shedding a third of the iPad 4's weight for its latest model. The next generation iPad will keep its 2048 x 1536 Retina display by using a thinner 0.2mm piece of glass. Just one LED light bar will apparently be used for backlighting - the iPad 4 currently uses a 0.25mm glass substrate and two LED light bars. Supply chain sources in Taiwan told DigiTimes that the bezel ...

Recently, a new research has claimed that the so-called ecofriendly LED lights may cause permanent damage to your eyes. The study found that exposure to LED lights can cause irreparable harm to the retina of the human eye. According to Think-Spain.com, once the retina cells are destroyed by prolonged and continuous exposure to LED rays, they cannot be replaced and will not regrow. Researchers said this is caused by the high levels of radiation in the 'blue band' , and is likely to become a global epidemic in the medium term given that computer, mobiles and TV s...

Traditionally Gallium Nitride (GaN) LED devices are produced on either sapphire or silicon carbide (SiC) substrates, due to the good crystal lattice matching between the materials and the GaN, with typically 2” or 4” diameter material being used. Significant effort is being made to grow GaN on ubiquitous larger diameter (6” or greater) silicon wafers, a substrate that offers significant substrate cost reduction, together with the ability to process in automated IC production lines. Reasonable estimates are that potential savings on the order of 80% over tr...
