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.
Claims19
A lighting module, comprising:
- a carrier;
- a first metal circuit layer extending along a first direction and disposed on the carrier;
- a first transparent conductive layer extending along the first direction and covering the first metal circuit layer;
- a first insulating layer disposed on the first transparent conductive layer, wherein two sides of the first insulating layer are respectively defined as a first side and a second side;
- a second transparent conductive layer including a first conductive portion and a second conductive portion, wherein the first conductive portion is connected to the first transparent conductive layer and covers one portion of the first insulating layer, the second conductive portion is disposed on another portion of the first insulating layer, and a pitch is defined between the second conductive portion and the first conductive portion;
- a second metal circuit layer including a first circuit portion and a second circuit portion, wherein the first circuit portion covers the first conductive portion, the second circuit portion covers the second conductive portion, and a groove is formed between the second circuit portion and the first circuit portion;
- a bonding structure layer including a first bonding portion and a second bonding portion, wherein the first bonding portion is disposed between a surface of the first insulating layer and the first circuit portion, and the second bonding portion is disposed between the surface of the first insulating layer and the second circuit portion;
- and
- a plurality of lighting units arranged corresponding to the groove, wherein a positive electrode and a negative electrode of each of the lighting units are connected to the first circuit portion and the second circuit portion, respectively.
A display panel, comprising:
- a carrier, wherein a display area and a non-display area are defined on the carrier;
- a plurality of wiring parts disposed on a surface of the display area, wherein each of the wiring parts has an extension portion, and the extension portion extends to the non-display area;
- and
- a light-absorbing layer disposed on the non-display area, wherein a height of the light-absorbing layer is greater than a height of the wiring parts, and the light-absorbing layer covers the extension portions and is at least more than 12 μm in thickness;
- wherein a plurality of lighting units are disposed on the display area, and two sides of a bottom portion of each of the lighting units are respectively connected to the wiring parts.
