I’m trying to change the backlight of a computer monitor to incandescent or halogen. Can I buy a 19” LCD or larger without the backlight, and install my own light source, and where could I purchase it from? If this is not possible is there a 19” or larger monitor that I could easily take apart and try this with. A friend of mine tried this with a Dell 19” monitor, but was unable to get the light to shine through the LCD.
The reason for changing the backlight is I have problems with computers screens giving me headaches within 10 to 15 minutes. All LCD monitors cause this problem including CCFL backlit, LED, and even the iphone. I bought a 23” EIZO EV2336W monitor that is IPS and has no PWM when the brightness is above 20. Unfortunately this did not work.
Based on everything I have tried, I believe that it is the light itself that causes the headaches, and I think it has to do with the uneven spectrum of the light that it produces. I recently purchased a laptop made by SunBook that has a transflective screen. As long as the backlight is off I can use the laptop all day without any problems. The disadvantages are that I need a good light source to read the screen, the screen is only 10 inches, and the screen is black and white. The solution that I believe will work is switching out the backlight with an incandescent or halogen light. I know the incandescent will work since I had the light shine through a laptop LCD and it didn’t give me a headache. I need a larger stand alone monitor at work, and that’s why I tried the 19” monitor.
If I’m unable to get a regular LCD to work then I’ll probably get the 22” transparent LCD sold by Orion, and shine a light through the display. I’m not sure how the quality would be since it is a transparent screen and it costs nearly $700. If anyone has any suggestions I would appreciate it.
Thanks,
Michael
