Claim 28 is rejected under 35 U.S.C. 103 as being unpatentable over Chae et al. (US 20190164945 A1), in view of El-Ghoroury (US 10134802 B2), Liu et al. (CN 104716264 A), Bessho et al. (US 9091415 B2), Chae et al. (Fig. 6-7) (US 20190164945 A1), Chae et al. (Fig. 57) (US 20190164945 A1), Yanagawa et al. (CN 112655099 A), Ko et al. (US 20190304960 A1), Chang et al. (US 20150280075 A1), and Wang (US 8390009 B2) as applied to claim 27 above, and further in view of another different embodiment of Chae et al. (US 20190164945 A1), hereby referred to as Chae et al. (Fig. 26-27A). Regarding claim 28, Chae et al., El-Ghoroury, Liu et al., Bessho et al., Chae et al. (Fig. 6-7), Chae et al. (Fig. 57), Yanagawa et al., Ko et al., Chang et al. and Wang teach the micro LED display device [101, Fig. 11] according to claim 27. Chae et al., El-Ghoroury, Liu et al., Bessho et al., Chae et al. (Fig. 6-7), Chae et al.

Response to Arguments Applicant’s arguments with respect to independent claim 1 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. Applicant argues on pages 5-9, Section: Claim Rejections under 35 U.S.C. 103, in remarks filed February 25, 2026 that the current prior art of record does not teach the amendments to independent claim 1. Examiner agrees with Applicant; However, after a new line of search and consideration of the prior art, the amended limitations of independent claim 1 can be overcome by new considerations of primary reference Chae et al. (US 20190164945 A1), and newly cited source Liu et al. (CN 104716264 A). Applicant argues on page 6, in remarks filed February 25, 2026 that primary reference Chae et al. and secondary reference Jang et al. (US 10879419 B2) do not teach the amended claim 1 limitation of “the second transparent substrate is disposed between the third light-emitting unit and the second light-emitting unit”. Examiner agrees with Applicant; However, after a new line of search and consideration of the prior art, the amended limitation of claim 1 can be overcome by newly cited source Liu et al. (CN 104716264 A). Applicant argues on page 7, in remarks filed February 25, 2026 that primary reference Chae et al. does not teach the amended claim 1 limitation of “ the first embankment structure is overlapped with the second embankment structure along the vertical direction”. Examiner agrees with Applicant; However, after a new line of search and consideration of the prior art, the amendment to independent claim 1 can be overcome by new considerations of primary reference Chae et al. (US 20190164945 A1). Applicant argues on pages 8-9, in remarks filed February 25, 2026 that the current prior art of record does not teach the amended claim 1 limitation of “wherein the carrier, the first light-emitting unit, the first transparent substrate, the second light-emitting unit, the second transparent substrate, and third light-emitting unit are arranged in sequence along the vertical direction”. Examiner agrees with Applicant; However, after a new line of search and consideration of the prior art, the amended limitation of claim 1 can be overcome by newly cited source Liu et al. (CN 104716264 A). Applicant added New claims 25-29, no new matter was added. New claims 25-29 can be overcome by primary reference Chae et al., and secondary reference Wang (US 8390009 B2). Applicant argues on page 9, in remarks filed February 25, 2026 that independent claim 1 should be in condition for allowance, and all dependent claims either directly or indirectly dependent on independent claim 1 should be in condition or allowance. Examiner disagrees with Applicant due to at least the reasons mentioned above.
