Abstract
A mini light emitting diode (LED) backlight panel is provided, which includes a plurality of backlight sub-panels in a docking way. A light-filling region is disposed between the arbitrary adjacent two backlight sub-panels. Fluorescent powder or quantum dots are filled in the light-filling region. The mini LED backlight panel emits light to excite material of the light-filling region to emit light. Secondly, adopting design solutions of large and small light emitting angles in mixed arrangement on different heights of the light emitting surfaces in the mini LED backlight panel, improving brightness on the splicing position, thereby improving quality of light emitted from the mini LED backlight panel, and meanwhile is advantageous for an ultra-thin design of the backlight module.
