Conclusion

APPLICANT REBUTTAL: REMARKS
Applicant appreciates the thorough examination of the present application as evidenced by the Office Action of April 25, 2024. In view of the above amendments and following comments and rebuttal arguments, the application is now believed to be in condition for allowance.
I.   Status of the Amendments
Claims 1-20 were previously pending in this application, with claims 1, 14 and 15 being independent.
In response to the Office Action, the features of claim 3 have been incorporated into claims 1, 14 and 15. Claims 3 and 17 have been canceled.
Upon entry of the above amendments, claims 1-2, 4-16 and 18-20 are now pending, among which claims 1, 14 and 15 are independent. II.  Claim rejections under 35 U.S.C. § 103
Claim(s) 1-4, 7, 9-10, 12 and 14-17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Gustafsson et al. (US. Pub. No. 2017/ 0091549, hereinafter" Gustafsson") in view of Hsu et al. (US. Pub. No. 2007/ 0273778 , hereinafter "Hsu"),f urther in view of Lewis et al. (US. Pub. No. 2013/0050642, hereinafter"Lewis").
Claims 4-6, 8, 11, 13 and 18-20 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
Claim 1 now recites:
A display device, comprising:
a display panel, comprising a display region, a first region disposed outside the display region and extending along a first direction, and a second region disposed outside the display region and extending along a second direction, wherein the first direction is intersected
with the second direction; and
a plurality of photoelectric sensor assemblies, each of the photoelectric sensor assemblies being provided with a strip-shaped photosensitive region; wherein one portion of the plurality of photoelectric sensor assemblies are disposed in the first region, extension directions of the photosensitive regions of the portion of the photoelectric sensor assemblies being parallel to the second direction; the other portion of the photoelectric sensor assemblies are disposed in the second region, extension directions of the photosensitive regions of the other portion of the photoelectric sensor assemblies being parallel to the first direction; and each of the photoelectric sensor assemblies is configured to receive an optical signal reflected via eyes of a user and convert the optical
signal into an electric signal,
wherein the photoelectric sensor assemblies are arranged in two rows in each of the first region and the second region along a direction away from the display region, and the two rows of
photoelectric sensor assemblies are staggered.
As acknowledged by the Examiner, Gustafsson fails to disclose the photoelectric sensor assemblies, on this basis, Gustafsson fails to disclose the specific arrangement of the photoelectric sensor assemblies either.
Thus, Gustafsson at least fails to disclose the following distinguishing technical feature in amended claim 1: wherein the photoelectric sensor assemblies are arranged in two rows in each of the first region and the second region along a direction away from the display region, and the two rows of photoelectric sensor assemblies are staggered.
X
The right picture shows the structure in the above distinguishing technical feature. As can be seen from the picture, the photoelectric sensor assemblies comprise two rows that are staggered.
Furthermore, the Examiner alleged that the above distinguishing technical feature that belongs to original claim 3 has been disclosed by FIG. 2A of Hsu.
FIG. 2A
However, as can be seen from FIG.2A of Hsu on the left, only one row of photoelectric sensors 500 are provided at each edge of the display area in Hsu, and Hsu does not disclose providing two rows of photoelectric sensors, let alone disclosing that the two rows of photoelectric sensors are staggered. Thus, Hsu fails to disclose the above distinguishing technical feature, and even the combination of Gustafsson and Hsu cannot provide any enlightenment of adopting the above distinguishing technical feature, either.
The above distinguishing technical feature has not been disclosed by Lewis, and therefore even the combination of Gustafsson, Hsu and Lewis cannot provide any enlightenment of adopting the above distinguishing technical feature, either.
The above distinguishing technical feature is not conventional technical means in the related art, and therefore even the conventional technical means cannot provide any enlightenment of adopting the above distinguishing technical feature, either.
Thus, claim 1 is patentable.
Meanwhile, independent claims 14 and 15 are also patentable over the cited prior art. The dependent claims are therefore also patentable by virtue of their dependencies on the allowable independent claims, as well as for the additional elements recited therein.
Accordingly, Applicant respectfully requests withdrawal of the rejections under 35 U.S.C. § 103.
