Abstract: The backlight module provided by the present invention utilizes a reflection plate and a Fresnel lens disposed between the light-emitting diode (LED) light source and the reflection plate to form a side-lit LED backlight without a light guide plate, which can simplify optical structure of the backlight. From a point of view, heavy weight and high cost problems of the light guide plate is solved while improving illumination efficiency.

Abstract: Disclosed are a display panel and a manufacturing method thereof. The display panel comprises: a substrate, a plurality of conductive units and a plurality of Mini LEDs. A material of the conductive units is conductive ink, and the conductive ink comprises a prepolymer, a monomer, a conductive filler and a photoinitiator. The viscosity of the conductive ink itself is employed to adsorb the Mini LEDs to improve the transfer accuracy of the Mini LEDs and to prevent the weak adsorption between the Mini LEDs and the conductive units, which affects the electrical connection between the conductive units and the Mini LEDs.
