Abstract: Provided is a LED backlight module, display screen and detection method of a LED backlight module. The LED backlight module includes a substrate and multiple LED chips arranged on the substrate, one first detection group is arranged on the substrate for each LED chip of more than one LED chip arranged at an interval of N LED chips connected in series, where N is greater than or equal to 0, the first detection group includes a first positive electrode detection point and a first negative electrode detection point, the first positive electrode detection point and the first negative electrode detection point of the first detection group are respectively connected to a positive electrode and a negative electrode of the each LED chip.

Abstract: 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.
