As vantagens da retroiluminação LED em Displays de painéis planos
What does LEDs have over any other backlighting source? The three most important concerns any Notebook designer has to resolve are power, even lighting, and weight. LEDs beat all other solutions hands down.
- Power equals heat and power reduces battery life time between charges.
LEDs are a cool light source, the lamination to heat ratio is even better that that of fluorescent lighting. As a result LEDs provide more light per watt.- LEDs are chips. They are small and can be placed in a matrix pattern behind the panel to deliver an even uniform field of light across the entire viewing surface of the panel. Other sources like bulbs and tubes will generate hot spots (where the light is brighter) and producing an even field of light to the panel can be tricky and costly.
- Once again, LEDs are chips. Small and light weight. LEDs are the winners today and will remain so for some time to come.
