Abstract: A lighting module, an electronic device, and a display panel are provided. The lighting module includes a carrier, a first metal circuit layer, a first transparent conductive layer, a first insulating layer, a second transparent conductive layer, a second metal circuit layer, a bonding structure layer, and a plurality of lighting units. The bonding structure layer is configured to allow the second metal circuit layer to be well bonded to the first insulating layer, so that a resistance value of the lighting module is decreased, and a pressure drop is reduced.

Abstract: A safety needle assembly includes a barrel, a cannula seat mounted in a front open end of the barrel, a needle cannula fixed to the cannula seat, and a plunger. The cannula seat includes a guiding section and a coupling section. A coupling member is formed on a distal end of a connecting rod that extends forward from a front end of the plunger. The connecting rod and the coupling member are twisted when the coupling member is moving forward through the guiding section during forward movement of the plunger. When the coupling member has passed through the guiding section into the coupling section, the connecting rod and the coupling member return to their original positions, and the coupling member couples with the coupling section, allowing the cannula seat and the needle cannula to be withdrawn into the barrel when the plunger is pulled rearward.
