OLED Panel Pros and Cons. Due to its approach to color and brightness, OLEDs have great contrast ratios. There’s no need to block a backlight, so there’s no worries about light bleeding

The LED for reflected illumination uses one objective lens to perform the role of both an objective and condenser, so the necessary light flux diameter is smaller. With this design, the numerical aperture (NA) is perfectly matched. This results in the optimal focusing of light and collection of light at the sample plane.

LEDs require drivers for two purposes: 1. LEDs are designed to run on low voltage (12-24V), direct current electricity. However, most places supply higher voltage (120-277V), alternating current electricity. An LED driver rectifies higher voltage, alternating current to low voltage, direct current. 2.
