Why is there still a dim area in the center when the LED lights on four sides?


In some slim light boxes, there are LED lighting on four sides. But the slim light box still has dim area in the center like under  picture. What is it caused by? 


WilLite thinks the main reason is that the light guide plate is not effective. So they want to make up for it by LED lighting on four sides. But when the size of slim light box is a little big, the dim area in the center still is noticeable.


WilLite slim light boxes usually use LED lighting on one side or two sides.  Like A0, B0 and bigger size, WilLite will use LED lighting on two sides. While achieving high bightness, there is no dim area in the center as under picture.
