Is it possible for a LCD monitor to display black light?

Q. Can an LCD monitor create a black light effect the same as a black light bulb?

A. Yes and no.

It's basically very possible, as the lighting on a LCD screen is usually thanks to a few tiny cold-cathode fluorescent tubes. These tubes start out by generating "black light" inside the tube, then since most people want while light, the tube makers coat the tubes on the inside with a phosphor that emits while light when struck by UV light.

You can get uncoated CCFL tubes, and with a little careful work you could replace the tubes in your LCD display with the UV-emitting tubes.

But that would be kinda dumb, as the color selecting pixels will not do anything interesting withthe UV. Well, maybe the blue pixels will pass a little of the UV, but that's about it. Now if you were a bee and could see UV, you'd see an image of sorts on the screen. But I assume you're not and you can't do you wont.


Now thinking a bit more about your question, are you asking whether the LCD color pixels, instead of being little color filters backlit with white light, could they be color phosphors backlit with UV? Now that might actually work. Probably been thought of and patented though.


What is the Windows PC monitor equivalent to Apple Mac monitor?
Q. What is the Windows PC monitor equivalent to the Apple Mac monitor?
I'm not talking about programs or software, I'm talking about the actual hardware monitor.

A. Hi Melissa, hope sincerely you are fine.

If you are not talking about software, then certainly you mean the LCD technology behind! The LCD Panel inside iMacs are manufactured by LG, they are made in China and only assembled in California by Apple. For example the 27" LCD in iMac have the following specs: LED-backlit glossy widescreen TFT active-matrix liquid crystal display with IPS technology,
Resolution: 2560 by 1440 pixels,
Typical brightness: 375 cd/m2,
It can be attached to a wall mount, articulating arm, or other VESA-compliant mounting solution using the optional VESA Mount Adapter Kit. Technically speaking, it is really hard to get an equivalent Monitor using this LCD technology in the market presently. I don't find any monitor competing with the Apple LCD technology.

As for the Apple Cinema Display 27" (i.e monitor only) the following can be noted:
27-inch (diagonal viewable image size) thin film transistor (TFT) active-matrix liquid crystal display with in-plane switching (IPS).

Supported resolutions: 2560 by 1440 pixels, 1920 by 1080 pixels, 1280 by 720 pixels
Colors (maximum): 16.7 million
Aspect ratio: 16:9
Viewing angle: 178° horizontal; 178° vertical
Brightness (typical): 375 cd/m2
Contrast ratio (typical): 1000:1
Response time (typical): 12 ms

To get the equivalent for this is really really hard although not impossible. According to my experience, I haven't seen another display equivalent to the Apple Cinema Display. That said, the Apple Cinema Display has it's disadvantages as well for eg it uses a Mini Display Port!

I know that i haven't answer your question by naming to you the exact equivalent monitor but I say that I haven't found anything matching the Apple Cinema Display yet. If you happen to get one that can match Apple's, please do let me know.

I hope that I have been of some help while sharing my experience to you Melissa. Wish you good luck. All the best.
