Song does not teach where the display substrate further comprises a first color film part between the base substrate and the light emitting member and the first light emitting region, where the first driving unit is located between the first color film part and the base substrate.
Fig. 5 of Choi teaches a bottom-emitting light- emitting unit (Combination of Items PR, PG, PB and PW) comprises a plurality of auxiliary bottom light-emitting devices emitting white light (Paragraph 0038); and the display substrate further comprises: a first color film part (Item 900) located between a base substrate (Item 1010) and a light-emitting member (Combination of Items 700, 800 and 600) and in the first light-emitting region, and the first color film part comprises a plurality of first color filters (Items R, G, B and W) which are in one-to-one correspondence with the auxiliary bottom light-emitting devices, where a driving unit (Item 1061) is located between the first color film part (Item 900) and the base substrate (Item 1010).

It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have where an orthographic projection of the first driving unit on the base substrate does not coincide with an orthographic projection of the bottom emitting light emitting unit on the base substrate because the first drive transistor not coinciding with the bottom light emitting unit allows for the light being emitted from the bottom light emitting unit to travel through the display more efficiently (Nie Paragraph 0054).
Examiner’s Note 2: The Examiner notes that the language of the claim does not specifically define the metes and bounds of what is the first light emitting region and the second light emitting region. Therefore, the Examiner may interpret any region of the display that emits light as being the respective first or second light emitting region even if a single light emitting region includes parts of more than one light emitting unit.

Response to Arguments
Applicant’s arguments, see Applicant’s REMARKS, filed 007/01/2026, with respect to the rejection(s) of claim(s) 1 and 14 under 35 USC 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of Nie.
Examiner’s Note: The Examiner notes that while the overall combination of references previously relied upon to reject previous claims 1 and 14 does not read on amended claims 1 and 14, the Examiner does not agree with all of the Applicant’s specific agreements with regard to the references. Firstly, the Applicant argued that none of Chuang, Choi Nie, Liu, Song and Zhu fail to disclose “the display substrate further comprises a plurality of repeating units distributed in array; the repeating unit comprises the first light emitting region, the second light emitting region and the transparent region. The Examiner disagrees. Both Chuang and Song teach arrays of the three regions, Chuang throughout the entire display and Song along the border between top emission and bottom emission regions of the display device. Secondly, the Applicant argues that Chuang does not teach where the top emitting light emitting unit covers a driving TFT. The Examiner disagrees. Chuang teaches where the driving TFT T1 is included in the pixel circuit and Fig. 5 of Chuang teaches where the top emitting light emitting unit covers the pixel circuit, not just T3 and T4, which are shown in merely one cross section of Fig. 5. In the plan view of Fig. 5, the entire pixel circuit (which includes the driving TFT) is covered by the top emitting light emitting unit. Lastly, the Applicant argues at length about the references failure to teach a top gate transistor and a bottom gate transistor. However, no where in the claim language are a top gate transistor and a bottom gate transistor required. Instead, the claim language is directed to a top emission light emitting unit and a bottom emission light emitting unit which are taught by the references. As such, the Applicant’s specific arguments concerning these three issues are not persuasive.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
