Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim 4 recites the limitation "the second controller" in line 1. There is insufficient antecedent basis for this limitation in the claim.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 2 is rejected under 35 U.S.C. 103 as being unpatentable over Herschbach as applied to claim 1 above, and further in view of Tada (US 2021/0035528 A1, hereinafter “Tada”).
As to claim 2, Herschbach does not disclose the display device according to claim 1, comprising:
a temperature sensor, configured to sense a temperature of the display panel;
a first controller, configured to control the heat dissipation element; and

wherein the temperature sensor provides a first signal to the first controller according to the temperature (Para. 0081, 0092), and provides a second signal to the second controller (111; Para. 0055).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Tada to include an active heat dissipation element in the device disclosed by Herschbach. The motivation would have been to correct the brightness change caused by temperature change of light source with high precision (Tada; Para. 0034).
Claim(s) 3 is rejected under 35 U.S.C. 103 as being unpatentable over Herschbach and Tada as applied to claim 2 above, and further in view of Jee et al. (US 2023/0215322 A1, hereinafter “Jee”).

However, Wu (Fig. 3) discloses wherein the temperature sensor (20) is disposed between the display panel (10) and the heat dissipation element (8; Para. 0028, 0031).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Wu to arrange the temperature sensors in an array in the device disclosed by Herschbach. The motivation would have been to compensate for each pixel (Wu; Para. 0035).
As to claim 6, Herschbach (Fig. 5) in view of Tada discloses the display device according to claim 2. Wu further teaches wherein the display panel comprises a first substrate (“substrate”; Para. 0004), wherein the light emitting units (501) and the temperature sensor (513) are disposed on the first substrate (Para. 0059).

However, Hisatsugu (Fig. 2) teaches an adhesive layer, disposed between the non-light emitting side of the display panel (24) and the heat dissipation element (41; Col. 8 lines 43-48).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Hisatsugu to use an adhesive layer in the device disclosed by Herschbach. The motivation would have been to attach different parts together (Hisatsugu; Col. 8 lines 45-48).
Claim(s) 12-13 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Herschbach as applied to claims 10 and 16 above, and further in view of Lee et al. (US 2019/0108786 A1, hereinafter “Lee”).
As to claim 12, Herschbach does not expressly disclose the display device according to claim 10, wherein a difference between a refractive index of the light-transmitting layer and a refractive index of the light concentration units is greater than 0.5.
However, Lee teaches wherein a difference between a refractive index of the light-transmitting layer (“air”) and a refractive index of the light concentration units is greater than 0.5 (Para. 0009, the refractive index of air is about 1, therefore 1.8 – 1 is greater than 0.5).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Lee to have a high refractive index layer in the device disclosed by Herschbach. The motivation would have been to control the transmission of light (Lee; Para. 0066).

As to claim 17, Herschbach does not disclose the display device according to claim 16, wherein a thickness of the transparent layer is greater than the second substrate.
However, Lee teaches wherein a thickness of the transparent layer (120) is greater than the second substrate (150; Para. 0086).

Claim(s) 18 is rejected under 35 U.S.C. 103 as being unpatentable over Herschbach as applied to claim 1 above, and further in view of Zhu (US 11,092,719 B1, hereinafter “Zhu”).
As to claim 18, Herschbach does not disclose the display device according to claim 1, wherein a number of the light emitting units is less than a number of the light concentration units.
However, Zhu (Fig. 3A) teaches wherein a number of the light emitting units (315) is less than a number of the light concentration units (355).
It would have been obvious to one of ordinary skill in the art to combine the teaching of Zhu to have fewer light emitting elements in the device disclosed by Herschbach. The motivation would have been to provide different structured light pattern.
