In general, blue LEDs are used for mini-LED 2D Backlights. However, we have selected to use white LEDs and applied our new design concept, named Multi-Luminance Point Structure. As a result, we have achieved a lower power and thinner module with 1 LED per zone which is suitable for mobile products.
