We are in the very early stages of developing a new product and are attempting to identify the type of LCD screen backlight we want to use. We are using a regular segment LCD glass screen, the type that connects to the PCB via a zebra connector. We have identified a screen on another product that is absolutely beautiful and we're trying to determine what type it is. We suspect it's the backlight that is making the different, that is giving in the high quality look. It appears that the backlight is a solid sheet of light rather than a few single LEDs on the perimeter of the glass.
Here are two example photos and I'm hoping someone here can give some additional information on what kind of screen this is:
Here is another example:
It's the uniform distribution and blue-gray color that we find appealing. I've read that there are three common backlight technologies used:
Of those 3 options I suspect we're wanting a LED backlight. Furthermore there is edge layout and array layout. I'm sure there are even more options. I'm hoping that given the two above images you will be able to determine what backlight technology is used.
