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, 3-7, 9-16, 18 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Zhao et al. (US 2023/0097447 A1) in view of Qin et al. (US 2022/0413342 A1) and Kamada et al. (US 2018/0046031 A1).
Regarding claim 1, Zhao et al. teaches a display device comprising:
a backlight assembly with a mini light emitting diode (LED) (see paragraph [0020] where mini-LED is disclosed) that emit blue light (see paragraph [0020] where blue light is disclosed); and

In this way, the entire plastic frame 16 can be yellow.) mixed with a material used to manufacture the mold frame (see paragraph [0047] where plastic frame 16 is made of a yellow quantum dot material.) and enclosing the backlight assembly (12, [0018] “a backlight light source”),
wherein an inner portion of the mold frame (16; see figure 4A and 4B) is disposed proximate to an inner portion of the backlight assembly (12), such that a portion of the blue light emitted by the mini-LED (12, [0020] “the backlight light source 12 may be a millimeter light-emitting diode (Mini LED)”) strikes the inner portion of the mold frame (16, see Fig. 4B & Fig. 3 where light emitted from 12 may obviously strike or reach 16), and wherein an outer portion of the mold frame (16) is coupled with an inside portion (1112) of a back cover (11) of the display device.
Zhao et al. teaches a mini-LED but does not explicitly teach a plurality of mini LEDs.
Qin et al. (US 2022/0413342 A1) teaches a plurality of mini light emitting diodes (light emitting units 202; paragraph [0051] where mini light emitting diodes are disclosed.)
It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the display device of Zhao et al. to include a plurality of mini LEDs as taught by Qin et al. as an alternative and obvious design choice to achieve a desired illumination output.
Zhao et al. modified by Qin et al. does not explicitly teach wherein the mold frame is configured to affix a position of an optical film between a diffuser and a quantum dot sheet.

Claim(s) 2, 8 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Zhao et al. (US 2023/0097447 A1) in view of Qin et al. (US 2022/0413342 A1) and Kamada et al. (US 2018/0046031 A1) as applied to claims 1, 7 and 15, respectively, above and further in view of Vampola et al. (US 2015/0048395 A1), hereinafter referred to as Vampola’395.
Regarding claim 2, Zhao et al. modified by Qin et al. and Kamada et al. teaches the display device of claim 1, but Zhao et al. does not explicitly teach wherein the yellow phosphor is a yttrium aluminum garnet phosphor. Vampola’395 teaches a yellow phosphor that is a yttrium aluminum garnet phosphor (see paragraph [0026] where YAG phosphor may be used in the wavelength converting material).
It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the display device of Zhao et al. to include yellow phosphor that is a yttrium aluminum garnet phosphor as taught by Vampola’395 as an obvious substitution to convert the emitting light to achieve desired illumination output.
Regarding claim 8 Zhao et al. modified by Qin et al. and Kamada et al. teaches the display device of claim 7, but Zhao et al. does not explicitly teach wherein the yellow phosphor is a yttrium aluminum garnet phosphor.
Vampola’395 teaches a yellow phosphor that is a yttrium aluminum garnet phosphor (see paragraph [0026] where YAG phosphor may be used in the wavelength converting material).
It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the display device of Zhao et al. to include yellow phosphor that is a yttrium aluminum garnet phosphor as taught by Vampola’395 as an obvious substitution to convert the emitting light to achieve desired illumination output.
Regarding claim 17, Zhao et al. modified by Qin et al. and Kamada et al. teaches the display device of claim 15, but Zhao et al. does not explicitly teach wherein the yellow phosphor is a yttrium aluminum garnet phosphor.
Vampola’395 teaches a yellow phosphor that is a yttrium aluminum garnet phosphor (see paragraph [0026] where YAG phosphor may be used in the wavelength converting material).
It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the display device of Zhao et al. to include yellow phosphor that is a yttrium aluminum garnet phosphor as taught by Vampola’395 as an obvious substitution to convert the emitting light to achieve desired illumination output. Claim(s) 20 is rejected under 35 U.S.C. 103 as being unpatentable over Zhao et al. (US 2023/0097447 A1) in view of Qin et al. (US 2022/0413342 A1) and Kamada et al. (US 2018/0046031 A1) as applied to claim 1 above and further in view of Kishimoto et al. (US 2013/0329442 A1).
Regarding claim 20, Zhao et al. modified by Qin et al. and Kamada et al. teaches the display device of claim 1, but Zhao et al. does explicitly teach wherein the [yellow phosphor powder] is mixed with an amorphous thermoplastic polymer material.
Kishimoto et al. teaches a yellow phosphor powder (see paragraph [0078] where YAG:Ce fluorescent substance is disclosed) is mixed with an amorphous thermoplastic polymer material (see paragraph [0078] discloses an amorphous material).
It would have been obvious to one having ordinary skill in the art before the time of the effective filing date of the invention to modify the display device of Zhao et al. to include a yellow phosphor powder mixed with an amorphous thermoplastic polymer material as taught by Kishimoto et al. to rapidly release heat, which is generated when the fluorescent substance is excited from the YAG phosphor power to the outside and to prevent sealing material from being notably deteriorated (see paragraph [0078] of Kishimoto et al).
Response to Arguments
Applicant’s arguments with respect to claim(s) 1-20 have been considered but are moot in view of new grounds of rejection necessitated by applicant’s amendment of independent claims 1, 7 and 15. New reference, Kamada et al. (US 2018/0046031 A1), teaches the limitations of the amended claim independent claims. See rejection above.
Claims 2-6, 8-14 and 16-20 remain rejected based on dependency on a rejected base claim.
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.
