Maxik et al., is silent regarding the color conversion substrate configuration and material. the color conversion substrate comprising a plurality of color conversion patterns, the color conversion pattern comprising a matrix material and quantum dots dispersed in the matrix material; the quantum dots are configured to emit light under irradiation of the first light and the second light In the same field of endeavor, Song teaches a color conversion layer comprising a plurality of color conversion patterns, the color conversion pattern comprising a matrix material and quantum dots dispersed in the matrix material (¶ [0030]) in order to improve brightness since quantum dots are known to be a significantly brighter color conversion material. Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the color conversion layer, as disclosed by Song, in the color conversion layer of maxik et al., in order to improve brightness since quantum dots are known to be a significantly brighter color conversion material. The resultant the quantum dots are configured to emit light under irradiation of the first light and the second light of Maxik et al. Furthermore, one of ordinary skill in the art would have been led to using quantum dot technology as a matter of choice. Applicant(s) has not disclosed that the materials is for a particular unobvious purpose, produce an unexpected or significant result, or are otherwise critical and it appears prima facie that the process would possess utility using another configuration (In re Dailey, 357 F.2d 669, 149 USPQ 47 (CCPA 1966)). Regarding Claim 21, Maxik et al., teaches the display panel according to claim 20, wherein a difference between a peak wavelength of the first light and a peak wavelength of the second light is greater than or equal to 10 nm (¶ [0011]). Regarding Claim 22, Maxik et al., as modified by Song teaches the display panel according to claim 20, wherein the color conversion patterns include a first color conversion pattern and a second color conversion pattern (¶ [0030] of Song), the first color conversion pattern comprises a first matrix material and first quantum dots dispersed in the first matrix material, the first matrix material is configured to excite the second light under irradiation of the first light, and the first quantum dots are configured to emit a light of a first wavelength under irradiation of the first light and the second light, the second color conversion pattern comprises a second matrix material and second quantum dots dispersed in the second matrix material (¶ [0030] of Song), the second matrix material is configured to excite the second light under irradiation of the first light, and the second quantum dots are configured to emit a light of a second wavelength under irradiation of the first light and the second light, wherein the first wavelength is different from the second wavelength, and the color conversion patterns include a third color conversion pattern, the third color conversion pattern comprising a third matrix material (¶ [0030] of Song), and the third matrix material is configured to excite a light of a third wavelength under irradiation of the first light, wherein the first wavelength and the second wavelength are different from the third wavelength (¶ [0030] of Song). Motivation to combine would be the same as stated above. 2. Claim(s) 23, 25-26 rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yoon et al., (U.S. Pub. No. 2021/0257575 A1) Regarding Claim 23, Yoon et al., teaches a display panel, comprising: a light-emitting base substrate (100), the light-emitting base substrate (100) comprising a plurality of light-emitting elements (130), and is configured to emit a first light; and a color conversion substrate (400 [Wingdings font/0xE0] “color conversion area,” ¶ [0416]), the color conversion substrate comprising a plurality of color conversion patterns (400 of each plurality of subpixel, ¶ [0390]), the color conversion pattern comprising a matrix material and quantum dots (QD, ¶ [0388]) dispersed in the matrix material, wherein the matrix material is configured to excite a second light under irradiation of the first light, and the quantum dots are configured to emit light under irradiation of the first light and the second light, and wherein a difference between a peak wavelength of the first light and a peak wavelength of the second light is greater than or equal to 10 nm (¶ [0056]). Regarding Claim 25, Yoon et al., teaches the display panel according to claim 23, wherein the color conversion substrate further comprises scattering particles (scattering, ¶ [0392]) dispersed in the matrix material. Regarding Claim 26, Yoon et al., teaches the display panel according to claim 23, wherein the matrix material comprises at least one of: pyridine polymer, carbazole polymer, fluorene oligomer, polythiophene polymer, or polyphenylene vinylene polymer (carbazole, ¶ [0099]). 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 of this title, 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. 3. Claim(s) 24 rejected under 35 U.S.C. 103 as being obvious over Yoon et al., in view of Lazo Martinez et al., herein after referred to as Lazo et al. Regarding Claim 24, Yoon et al., teaches the invention set forth above (see rejection in the corresponding claim(s) above). Yoon et al., is silent regarding a third matrix material is configured to excite a light of a third wavelength under irradiation of the first light, wherein the first wavelength and the second wavelength are different from the third wavelength. In the same field of endeavor, Lazo et al., teaches the color conversion patterns include a first color conversion pattern (CVF1) and a second color conversion pattern (CVF2), the first color conversion pattern comprises a first matrix material and first quantum dots dispersed in the first matrix material, the first matrix material is configured to excite the second light under irradiation of the first light, and the first quantum dots (QD, ¶ [0095]) are configured to emit a light of a first wavelength under irradiation of the first light and the second light, the second color conversion pattern comprises a second matrix material and second quantum dots dispersed in the second matrix material, the second matrix material is configured to excite the second light under irradiation of the first light, and the second quantum dots are configured to emit a light of a second wavelength under irradiation of the first light and the second light, wherein the first wavelength is different from the second wavelength, and the color conversion patterns include a third color conversion pattern (CVF3), the third color conversion pattern comprising a third matrix material, and the third matrix material is configured to excite a light of a third wavelength under irradiation of the first light, wherein the first wavelength and the second wavelength are different from the third wavelength in order to improve and expand the marketability of the display by incorporating a greater variety of light output wavelengths. Therefore, 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 third color conversion pattern as disclosed by Lazo et al., in the device of Yoon et al., in order to improve and expand the marketability of the display by incorporating a greater variety of light output wavelengths. Allowable Subject Matter A. Claim(s) 1-7, 9, 12, 14, 16-17, 19 are allowed over the prior art of record.
