uniform brightness meaning in Chinese
等亮度
Examples
- Mura is a japanese word meaning blemish that has been widely adopted by the display industry to provide a name for low contrast , non - uniform brightness regions , typically larger than single pixels
Mura一词来源于日语,原意为脏污或斑痕,现已被显示器行业普遍接受,专门用来表示一类对比度低、亮度不均匀、面积大于一个像素的面缺陷。 - The outside of this chip adopts boost structure to drive up to seven white leds with the input voltage ranging from 3v to 5v . series connection of the leds provides identical led current resulting in uniform brightness
电路的电源输入在3v 5v变化,采用boost电路结构升压,在极限情况下最多可驱动七个白光led ,由于led串联,因此各led电流完全匹配,亮度一至。 - Due to characteristics of white led such as large forward voltage and high temperature sensitivity , and necessity of uniform brightness requirement of the portable application , specially designed power management ic is needed
由于便携式应用对白光led亮度均匀性的要求,以及白光led自身的正向导通电压大、电学参数离散性大、容易受温度影响等特点,需要设计专门的电源管理芯片来驱动白光led 。 - A high - efficiency white led driver based on charge pump was designed in this paper , which introduces the structure of charge pump to perform the conversion of rising input voltage , drives up four white leds in parallel with regulated constant current and keeps all leds with uniform brightness
本文设计了一种基于电荷泵的高效率白光led驱动电路。它采用电荷泵结构对输入电压进行升压变换,以可调节的恒定电流驱动并联的4只白光led ,并保持每个led的亮度相同。
