Abstract: A camera module. The camera module includes a lens barrel, and a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens having a negative refractive power provided in the lens barrel, and a spacer arranged between the sixth lens and the seventh lens on the optical axis of the camera module. An effective focal length f7 of the seventh lens, an inner diameter d6m of an image-side surface of the sixth spacer, an air interval T67 between the sixth lens and the seventh lens along the optical axis, and a maximum thickness CP6 of the sixth spacer satisfy: 1.0<|d6m/f7|+T67/CP6<8.5.

Abstract: An optical camera lens assembly is provided, including: a lens group, including a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens arranged sequentially along an optical axis from an object side to an image side, where, each of the first, the fourth, and the sixth lens has a positive refractive power, and each of the second, the third, the fifth, and the seventh lens has a negative refractive power; and a plurality of spacing elements, including a third spacing element disposed between the third lens and the fourth lens and in contact with an image-side surface of the third lens; the optical camera lens assembly satisfies: 3.0<(R3+R4)/d3s<5.0.

Abstract: An optical imaging lens assembly is provided, including: an imaging lens group, a plurality of spacing elements, and a lens barrel configured to accommodate the imaging lens group and the plurality of spacing elements comprising a third spacing element that is placed between the third lens and the fourth lens and is in contact with an image-side surface of the third lens. Here, an inner diameter d3s of an object-side surface of the third spacing element, a radius of curvature R5 of an object-side surface of the third lens and a radius of curvature R6 of the image-side surface of the third lens satisfy: 5.0<d3s/(R5+R6)<10.5.

Abstract: Some embodiments of the disclosure provide an optical imaging lens assembly and a display device. The optical imaging lens assembly includes: a lens barrel, a lens, and a microstructure. The lens barrel has a body and a mount hole disposed on the body; the lens is disposed in the mount hole; and an outer wall surface of the body and/or an inner wall surface of the mount hole is provided with the microstructure.
