A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at effective filing date to a person having ordinary skill in the art to which said subject matter pertains.

Claims 1-8 and 10-16 are rejected under 35 U.S.C. 103 as being unpatentable over Jin (US 20180315803 A1, cited previously) in view of Zeng (CN 110709860 A, cited by Applicant, cited previously) and further in view of Wang (CN 210867853 U)
Regarding claim 1, Jin teaches a display module (at least Fig.10, 4-5,7-9), comprising: a display panel 110 having a display surface and a back surface opposite to the display surface, and having a fingerprint identification area (upper surface 111;[0025]); and a light-transmitting protective film (120 that has a light transmitting hole 121,[0032] OR 215) located on the back surface of the display panel, the light-transmitting protective film includes: a protective layer having a target area (hole area), wherein at least the target area is a light-transmitting area, and the target area at least partially overlaps with the fingerprint identification area; a light-shielding pattern (130) located on a side of the protective layer, wherein the light-shielding pattern defines a plurality of imaging apertures (light penetrating passages 133, [0034],[0036]) , the plurality of imaging apertures are disposed at intervals, and orthogonal projections of the plurality of imaging apertures on the protective layer are at least located in the target area.
Jin teaches the display panel 110 attached to the light shielding layer 130 (fig.5), wherein the attachment has to be a bonding layer/adhesive layer that is transparent to allow light to pass through the light passages 133, since, if the surface 112 that attaches the display 110 to the light shielding pattern 130 is not transparent, then the light is blocked from passing from the display panel 110 to the opening 121 (in Fig.4).
However, Jin does not explicitly teach a light-transmitting adhesive layer located on a side of the light-shielding pattern away from the protective layer, wherein a surface of the light-transmitting adhesive layer away from the light-shielding pattern is in contact with the display panel.
Zeng explicitly teaches a light-transmitting adhesive layer 400 (at least Fig.6, Zeng: include transparent soft rubber layer 400) located on a side of the light-shielding pattern away from the protective layer 500 (fixing component that protects the upper optical layers), wherein a surface of the light-transmitting adhesive layer away from the light-shielding pattern is in contact with the display panel 120 (flexible display screen 120 of the display).

It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention to add the inverted image feature, as disclosed in Wang, in the device of Jin in view of Zeng in in order to achieve a relatively complete image of the object ( Thus, according to the small hole imaging principle, small hole plate 101 on the other side of the object light, can pass through the imaging hole, the image sensor 102 is formed on the object of the inverted image. through each imaging hole of the light can form a corresponding image on the image sensor 102, the plurality of images to splice, can obtain a relatively complete image of the object).
