刚用单反测试了下我的Dell U2412m(LED背光)和Samsung P2770HD(老式CCFL背光),
测试方法参考:
http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm
快门试了1/2s到1/200s
P2770HD始终没有明暗条纹,偶尔有颜色过渡。之前一直用这个显示器,眼睛没有什么
不适,就是颜色表现力太差。
U2412m在最高亮度的时候,1/40s以上还是能看到明显的明暗条纹(我的条纹是上下间
隔的,不是如上网页左右间隔的),最低亮度时更明显,更多,1/2s快门就能看到。还
是把它卖了算了。

来自主题: Hardware版 - 关于LED背光下的蓝光伤眼问题
CRT表现白色应该是蓝绿红光强度相等(不确定)。白光是人眼的主观感受,可能由不
同组合的光线群组成,显示器用的led和ccfl表现白光的方式可参见:
http://pcmonitors.info/forum/topic/is-w-led-backlighting-bad-re
一般来说,绿光对人眼最好好,人眼对绿光的敏感度也最高,蓝光或频率更高(光子能
量更高)的光对人眼有害。pc显示器用的白光led的发光机制是蓝光led部分光线射出,
部分激发黄绿荧光粉(低能级光子只能由高能级光子激发),产生白光,这样导致了白
光中,蓝光成分过多,看久了会刺激眼睛。

亮度不是问题,可以调低。LED背光毁眼的主要原因是PWM调光机制。只要买flicker
free的显示器就行了。以下是flicker free显示器列表:
http://www.tftcentral.co.uk/articles/flicker_free_database.htm
我以前买过dell u2412,用了两个月眼睛实在受不了给退了。现在用的是eizo ev2436w
。显示方面没的说,操作方面有些不顺手。不过本品厂家保修5年,全亮度范围非pwm调
光,主打护眼功能,还是比较值得买。

你这不是背光的问题吧,是屏幕是镜面屏。换个雾面屏的LED显示器就行,LCD不好找

你好,请问NEC - MultiSync 24" LCD Monitor - Black 是否是flicker
free的显示器,我在您给的网站上没找到。NEC - MultiSync 24" LCD Monitor
Sale: $524.98的价位是否比其他的LED的显示器护眼,更值得入手那,谢谢!

明确型号是多少?
如果列表中没有,那么不能确定是否flicker free。要保险,最好买list里的。
525刀应该算是中高档显示器了,但是“高”不一定在护眼方面,可能在色彩图像表现
方面,你不一定用的着。如果只是打字上网看电影,BenQ BL2411PT就够了,应该不到
300块,这款也是号称专注护眼,16:10的屏幕看文档也不错。

多谢了!

看来北美市场还没大量引进Benq这款,所以比较贵。那你就按照list上的显示器在
Amazon上找,看看哪款价格能接受。如果懒得找的话,就买eizo ev2436w。这款主打护
眼和节能,除了pwm free之外,有两个光学传感器,能根据环境光自动调节亮度。但我
不太喜欢它的自动调节功能,基本每次都是手动调到我想要的亮度。它还有几个预设显
示模式,对于不太懂显示器校准的人来说,比较方便。Bestbuy上这款现在477.49:

do not know which part you are talking about,
and not sure about LCD, I think they still use CCFL as back light,some
small size and new product maybe use LED.
for Plasma Display Panel, lots of FPGA and lots of driver chips on the
backside., the control is relatively complex.
if you wonder the digital signal input/output and signal processing, I
totally know nothing...

random list
1. integrated planar inductor
2. LED (boost) controller IC
3. integrated backlight (CCFL type) DCDC resonant controller IC
4. DCDC IC with very wide input voltage range (such as automotive load dump
capable)
5. integrate DCDC/analog into FPGA
6. long shot: high power DCDC with SiC FET/diode
7. $$$: <1 cent LDO
applications
1. EV
2. energy efficiency (LED lighting etc)
3. renewable energy
4. wearable and flexible electronics
5. IPhone etc

This is a great LCD for gaming or response time. Little off axis issues
like the newer sets suffer. Will use a bit more watts with CCFL lit, but
IMO is a better picture.
