Embodiment 1

[0045] like Figure 1 to Figure 10 As shown, in Embodiment 1 of the present invention, the optical imaging system includes a plurality of bosses 11 and a plurality of grooves 21 corresponding to the plurality of bosses 11, and the plurality of bosses 11 are along the circumference of the lens barrel 10 The plurality of grooves 21 are arranged at intervals along the circumferential direction of the lens 20 .

[0046] According to the above setting, the one-to-one matching arrangement of a plurality of bosses 11 and a plurality of grooves 21 enables the lens 20 to be more embedded in the lens barrel 10, and the contact area between the lens 20 and the lens barrel 10 is larger, thereby better The assembly strength of the lens barrel 10 and the lens 20 has been greatly improved, and the problem that the lens barrel 10 is easily deformed when the lens barrel 10 and the lens 20 are assembled due to the small assembly strength is more effectively avoided, and the optical imaging syst...

Embodiment 2

[0077] like Figure 12 to Figure 18As shown, in the second embodiment of the present invention, the optical imaging system includes a plurality of bosses 11 and a plurality of grooves 21 corresponding to the plurality of bosses 11, the difference between the second embodiment and the first embodiment It lies in the number of bosses 11 and grooves 21 . In the second embodiment, 21 bosses 11 are arranged at intervals along the circumference of the lens barrel 10 , and 21 grooves 21 are arranged at intervals along the circumference of the lens 20 .

[0078] like Figure 14 As shown, different from the first embodiment, in the second embodiment, the projection of the boss 11 on the first plane 30 is an isosceles triangle, and when the distance between the outer surface of the boss 11 and the axis of the lens barrel is the largest The point at point M is point M, and the tangent plane at point M is the first plane 30 . In the above arrangement, the boss 11 is arranged as an isos...

Abstract

The invention provides an optical imaging system and a display device. The optical imaging system includes: a lens cone; a lens disposed inside the lens barrel; a boss arranged on the inner wall surface of the lens cone; a groove formed in the outer wall surface of the lens, wherein the groove is matched with the boss. According to the technical scheme, the problem that in the prior art, due to the fact that the assembling strength of the lens cone and the lens is reduced, the lens cone is prone to deformation during assembling is solved.

Description

technical field [0001] The present invention relates to the imaging field of optical imaging systems, in particular to an optical imaging system and a display device. Background technique [0002] Against the background of the rise of full-screen mobile phones, manufacturers have higher and higher requirements for product appearance and imaging quality. Optical imaging systems are developing in the direction of small size and high pixels, which requires the outer diameter of the lens barrel and lens to be smaller and smaller. However, if the size of the lens barrel is too small, it will not only affect the shaping of the lens barrel, but also affect the MTF (Modulation Transfer Function) yield of the optical imaging system. Due to the reduction of the size of the lens, the wall thickness of the lens barrel will be reduced, which may reduce the assembly strength of the lens barrel and the lens, and the lens barrel will have the risk of assembly deformation, which may lead to...
