Abstract
The present invention provides a backlight module and a display device using the backlight module. The present invention has the following advantage: An LED light shadow can be effectively optimized, and an overall display effect of a mini-LED can be improved; a problem of a mini-LED light shadow is optimized without increasing a module thickness and a module power loss as much as possible; and with a same thickness, a design of fewer LED lights can be implemented, and costs of medium- and large-sized mini-LED modules can be reduced.
