Information Disclosure Statement
The information disclosure statement (IDS) submitted on 03/18/2024 has been considered by the examiner.
Response to Amendment
Receipt is acknowledged of applicant’s amendment filed 09/23/2023. Claims 1-20 are pending and an action on the merits is as follows.
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) 1, and 19-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Roh, US 20210143223 A1, ids of record) in view of Kamurah et al.( WO 2017033771 A1 ids, of record) (Kamurah ,hereafter).
Regarding claims 1 and 20, Roh discloses a display substrate (100( and a color conversion substrate (Figure 3-Figure 16 and corresponding text), (Figure 4 comprising: a base substrate (second substrate (BS2)); isolation portion (CF2) on a side of the base substrate (BS2), a plurality of pixel apertures(PXA) being defined in the isolation portion (CF2), wherein the plurality of pixel apertures comprise a plurality of first-type pixel (PXA-R) apertures arranged in arrays and a plurality of second-type pixel(PXA-B) apertures arranged in arrays (π71-π73), and a plurality of lines of the first-type pixel apertures and a plurality of lines of the second-type pixel apertures are alternately arranged (See Figure 3); and a color conversion layer(WCL, light control portions),comprising a first color conversion pattern (WCL1), a second color conversion pattern (WCL2), and a transmission pattern (no number), wherein the first color conversion pattern and the transmission pattern are disposed in different first-type pixel apertures, and the second color conversion pattern is disposed in the plurality of second-type pixel apertures; wherein the second-type pixel apertures(PXA-B) are not defined in a first region in the color conversion substrate(BS2) for defining a same line of the first-type pixel apertures (PXA-R), and the first-type pixel apertures(PXA-R) are not defined in a second region in the color conversion substrate (BS2) for defining a same line of the second-type pixel apertures(PXA-B) (π74-π77). Roh fails to disclose that the isolation portion is reflective.
Kamurah discloses a wavelength conversion substrate 20, comprising a substrate 24, a partition wall 21, and a wavelength conversion portion 22. The partition wall 21 has light reflectivity, and can reflect light, which is converted by the wavelength conversion portion 22, to a viewer side, thereby improving the light extraction efficiency.
Therefore it would have been obvious to one of ordinary skill in the art before the effective filing date to modify the display and color conversion substrate of Roh as disclosed by Kamurah wherein the isolation portion is reflective the motivation being to recycle light to improve light extraction and brightness.
Regarding claim 19, the wording for this claim is similar to claim one such that the rejection would apply matis mutandis .
Allowable Subject Matter
Claim 2 is 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. Claims 3 -18 are objected to due to their dependency upon claim 2.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure can be found in the 892 or below:
