摘要： Some embodiments provide a full-color display module and display device. The full-color display module includes at least two light-emitting layers. Any one of the at least two light-emitting layers includes a substrate and a plurality of light-emitting portions encapsulated on the substrate. A type of any one of the plurality of light-emitting portions is one of a red light-emitting portion, a green light-emitting portion, and a blue light-emitting portion. The at least two light-emitting layers are successively laminated in a laminating direction and form a plurality of pixel points. Any one of the plurality of pixel points is a surrounding area on the full-color display module, which is surrounded by a surrounding curved surface. The surrounding area of the any one of the plurality of pixel points includes at least one red light-emitting portion, at least one green light-emitting portion, and at least one blue light-emitting portion.

摘要： The disclosure provides an LED white light device, including a blue light chip and phosphors. The blue light chip has a band of (455-470) nm. The phosphors include a dual-band yellow phosphor and a red phosphor having an excited light peak wavelength range of (610-660) nm. The yellow phosphor and the red phosphor are mixed according to a proportion of 1:(0.03-0.2) and cover the blue light chip, such that blue light emitted by the packaged LED white light device has a peak wavelength range of (450-465) nm. The disclosure also provides a preparation method of an LED white light device and an LED backlight module adopting the above LED white light device. The disclosure achieves the effects of blue light prevention, high color gamut and pure white simultaneously, the color uniformity and consistency are good, and a blue-green-red three-color continuous spectrum is provided, which is closer to a solar spectrum.

摘要： An LED bracket, LED bracket array, LED device and LED display screen are disclosed. The LED bracket includes a PCB circuit substrate and an insulating material. The PCB circuit substrate includes at least two electrically insulated electrode regions. Each electrode region includes a top electrode region, a side electrode region and a bottom electrode region. The side electrode region connects the top electrode region and the bottom electrode region into an integrated structure. The side electrode region is a side surface sunk from outside to an inner part of the PCB circuit substrate. The insulating material is filled in the side electrode region. An upper end surface and a lower end surface of the insulating material do not exceed an upper surface and a lower surface of the PCB circuit substrate. A thickness of the insulating material is less than a thickness of the PCB circuit substrate.
