I needed to know the geometry of some common LCD panels for a project I’m working on. I couldn’t find a convenient chart, so I am contributing this one to the Internet. I worked out the X and Y values with some simple trig. An alternative estimation based on resolution multiplied by pixel pitch yields similar results ±0.125”.

Hello Jon,
I’m interested in your data concerning the LCD panel dimensions. Could you tell me more about it? I’ve been trying to get some overview on LCD panel (outer) dimensions.
Please drop me a line!
Thanks,
Guido
hey there and thanks in your information ? I have certainly picked up something new from right here. I did then again experience a few technical issues the use of this site, since I skilled to reload the web site lots of times previous to I could get it to load correctly.
