Over the past decade, LEDs have taken over the consumer market by storm; and for good reason. Incandescent and Compact Fluorescent Lighting (CFL) are now often seen as a relic from the past. Here are a few reasons why consumers are now using LEDs over any other form of light source. Si...
led和lcd的区别(ThedifferencebetweenLEDandLCD)LCD液晶显示的简称液晶显示器是,液晶的构造是在两片平行的玻璃当中放置液态的晶体,两片玻璃中间有许多垂直和水平的细小电线,透过通电与否来控制杆状水晶分子改变方向,将光线折射出来产生画面。比CRT要好的多,但是价钱较其贵液晶液晶投影机是液晶显示技术和投影技术相结合的...

fluorescent light, or incandescent light. Coatings companies often utilize standard light source light boxes or colorimeters to ensure uniform and comparable measurement results. Especially when it comes to color matching at night, the role of standard light source light boxes is particularly important....
Last but not least, durability is also a feature of chip LEDs. LED chips may have longer life spans than incandescent light bulbs in common situations. What are the Applications of Chip LEDs? The technology of LEDs is constantly evolving. The brightness of the light produced by chip LEDs is...
QLED, Mini-LED, and microLED TVs are all LED TVs The acronym LED stands for "light-emitting diode," a technology that dates back to the 1960s. LED is a tiny digital light bulb that uses semiconductors to produce light, rather than the organic processes used in an incandescent or fluoresce...
