Wendy Luiten Philips Research, Eindhoven, the Netherlands INTRODUCTION Active LEDs in a consumer TV product are boosted and dimmed with the video picture content. Boosting and dimming of the LEDs is a powerful means to improve visual experience, either through application of active LEDs in an ambient light feature, or through dimming and boosting of the display LEDs in a … [Read more...]
New Plastic Helps Prevent Phones from Overheating
A new plastic material could significantly reduce problems associated with overheating mobile phones, say researchers from Loughborough University in England. Known as ultra-high molecular-weight polyethylene (UHMWPE), the new plastic, unlike the ones currently used in mobile phone covers, dissipates the heat created by the lithium batteries and reduces the likelihood of … [Read more...]
Advances in Vapor Compression Electronics Cooling
INTRODUCTION Over the last 10 years, there has been a well-documented increase in the energy density of electronic devices. As this energy density has gone up, so has the heat dissipation on electronics packages. In response to this challenge, significant research has taken place to develop chip level cooling systems to meet heat fluxes in excess of 1000W/cm2. As stated … [Read more...]
Thermal Material Provides Both Compressibility and Conformability with Phase-Change Ability
AI Technology, Inc. has released COOL-PAD™ CPR7154, a thermal interface material that dispenses like a thermal pad but exhibits characteristics like that of a grease or gel when device temperatures increase to above 45°C. Ideal for use in LEDs, gaming consoles, laptops and desktop computers, COOL-PAD™ CPR7154 is optimized to accommodate large areas with different heights and … [Read more...]
Flexible Thermoelectric Generator Could Power Wearable Devices Using Body Heat
Researchers have developed a new thermoelectric generator that could replace batteries as a more versatile power source. As interest grows in wearable electronics like Google Glass, smartwatches and fitness trackers, finding a suitable, long-lasting reliable power supply for these devices becomes an increasingly important concern for designers. Now, a team of researchers from … [Read more...]
