Abstract
A display module, an LED optical device and a manufacturing method therefor. The display module and the LED optical device each includes a substrate (1), a plurality of light-emitting units (2) arranged on the top surface of the substrate (1), and a packaging layer (3) arranged on the substrate (1) and covering each light-emitting unit (2), where each light-emitting unit (2) includes at least one LED chip, and the packaging layer (3) is configured to transmit light emitted by the LED chip.
Claims21
-22. (canceled)
A display module, comprising:
- a substrate, comprising a chip receiving region and a concave portion extending from the chip receiving region toward a periphery;
- a plurality of light-emitting units, each comprising a plurality of light-emitting elements, arranged in the chip receiving region, and electrically connected to the substrate;
- a black optical layer, arranged on the substrate and not covering upper surfaces of the plurality of light-emitting units, wherein a surface of the black optical layer comprises uneven microstructures;
- and
- a light-transmitting protection layer, arranged on the black optical layer.
An LED light-emitting device, comprising:
- a substrate;
- a plurality of light-emitting units, each comprising a plurality of light-emitting elements, arranged in the chip receiving region, and electrically connected to the substrate;
- a black optical layer, arranged in a gap between the substrate and the plurality of light-emitting units, wherein a height of the black optical layer is less than a height of the light-emitting unit;
- an optical element, arranged on light-emitting surfaces of the light-emitting elements and the black optical layer in a completely fitted manner, wherein a surface of the optical element comprises optical microstructures;
- and
- a light-transmitting protection layer, arranged on the optical element.
An LED display module, comprising:
- a substrate;
- a plurality of light-emitting units, each comprising a plurality of light-emitting elements, arranged in the chip receiving region, and electrically connected to the substrate;
