`
`DETAILED ACTION
`
`Notice of Pre-AIA or AIA Status
`
`The present application, filed on or after March 16, 2013,
`
`is being examined under the
`
`first inventor to file provisions of the AIA.
`
`Claims 1 and 2 have been amended. Claims 11 and 12 have been amended.
`
`Response to Amendment
`
`Response to Arguments
`
`Applicant’s arguments with respect to claim have been considered but are moot because
`
`the arguments do not apply to the new grounds of the current rejection.
`
`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, notwithstandingthat 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.
`
`Claims 1, 3, 7, 8, 9, 10, 11, and 12 are rejected under 35 U.S.C. 103 as being
`
`unpatentable over Takata US 7800714.
`
`Regarding claim 1, Takata teaches a liquid crystal display device (fig 24)
`
`comprising:
`
`a liquid crystal cell (upper stacked panel), an optical sheet (optical sheets), and a
`
`backlight (lower backlight) disposed apart from one another (fig 24), the backlight (lower
`
`backlight) including alight source (light source, fig 22, 24);
`
`

`

`Application/Control Number: 15/695,701
`Art Unit: 2871
`
`Page 3
`
`a heat absorber (cooling device; pump creating circulation of transparent fluid, fig
`
`24) that is disposed in an airtight circulation channel (channel; space formed between the
`
`stacked panels and the lighting system, fig 24) and cools a coolant (transparent fluid) that
`
`circulates in the airtight circulation channel (channel, fig 24) so as to pass through a first
`
`channel between the liquid crystal cell and the optical sheet (first side channel, figs 24 and
`
`28);and a heat sink (heat sink, fig 24) that is thermally coupled to the heat absorber
`
`(cooling device; pump, fig 24) and exposed to ambient air (as per fig 24; col 20, lines 44—
`
`54, carrying heat away, so as to discharge the heat through a heatsink).
`
`However, Takata does not explicitly disclose in fig 24 a second channel between
`
`the optical sheet and the backlight with the light source of the backlight exposed to the
`
`second channel for the purpose of enabling rapid internal cooling of the light sources.
`
`The fig 22 embodiment of Takata discloses a second channel (channel for airflow,
`
`fig 22) between the optical sheet (optical sheets, fig 22) and the backlight (backlight of
`
`light source, fig 22) with the light source (light source, fig 22) of the backlight (backlight of
`
`light source, fig 22) exposed to the second channel (channel for airflow, fig 22)(col. 20,
`
`lines 20—34) for the purpose of enabling rapid internal cooling of the light sources (col. 20,
`
`lines 20—34)for the purpose of enabling rapid internal cooling of the light sources (col. 20,
`
`lines 20—34).
`
`It would have been obvious to one of ordinary skill
`
`in the art at the time of the
`
`invention to modify the airtight circulation chamber taught in fig 24 of Takata with the
`
`second channel configuration of fig 22 of Takata for the purpose of enabling rapid internal
`
`cooling of the light sources (col. 20, lines 20—34).
`
`

`

`Application/Control Number: 15/695,701
`Art Unit: 2871
`
`Page 4
`
`Regarding claim 3, Takata teaches the liquid crystal display device according to
`
`claim 1, further comprising: an intermediate frame (fig 24; back chassis as better described
`
`in fig 20) for holding the optical sheet (optical sheets, fig 20), wherein the intermediate
`
`frame (back chassis, fig 20) includes an intermediate component (fig 24; channel chassis
`
`for fluid flow) provided with a through hole (passage in side walls at end of intermediate
`
`frame, fig 24) for communicatively connecting the first channel (first side channel, figs
`
`24) and the second channel (second side channel, fig 24).
`
`Regarding claim 7, Takata teaches the liquid crystal display device according to
`
`claim 1, wherein the heat sink (heat sink, fig 24) includes heat—dissipating fins (fins on heat
`
`sink) outside the airtight circulation channel, behind the backlight (backlight).
`
`Regarding claim 8, Takata teaches the liquid crystal display device according to
`
`claim 7, however does not teachin fig 24 further comprising: a fan outside the airtight
`
`circulation channel, behind the backlight, for introducing ambient air into spaces between
`
`the heat—dissipating fins.
`
`Takata teaches in fig 20 a fan (105) outside the airtight circulation channel, behind
`
`the backlight, for introducing ambient air into spaces between the heat—dissipating fins (fig
`
`20; col 20, line 64, col 21, line 4) for the purpose to further cool down the liquid crystal
`
`display.
`
`Although Takata teaches the a fan 105 blowing air at the back chassis, primarily
`
`made of metal, to cool down the liquid crystal display,
`
`it would have been obvious to one
`
`skilled in the art before the effective filing date of the claimed invention to have fan 105
`
`blowing air at the heat—dissipating fins of the heat sink located behind the backlight in fig
`
`24 to further cool down the liquid crystal display.
`
`

`

`Application/Control Number: 15/695,701
`Art Unit: 2871
`
`Page 5
`
`Regarding claim 9, Takata teaches the liquid crystal display device according to
`
`claim 7, wherein the heat sink (heat sink, fig 24) includes a heat—dissipating plate (base
`
`portion of heat sink), the heat—dissipating fins (fins on heat sink) stand on a rear surface of
`
`the heat—dissipating plate (base portion of heat sink), and the backlight (backlight) and the
`
`heat absorber are disposed in front of the heat—dissipating plate (as per fig 24).
`
`Regarding claim 10, Takata teaches the liquid crystal display device according to claim
`
`1, wherein the heat absorber (cooling device; fig 24) is disposed in an uppermost portion of
`
`the airtight circulation channel (channel, fig 24) when the liquid crystal display device stands
`
`vertically (as per fig 24). Although Takata teaches the heat absorber being located in a bottom
`
`portion of the airtight circulation channel,
`
`it would have been an obvious matter of design choice
`
`to locate the heat absorber being located in an upper portion of the airtight circulation channel,
`
`since Applicant has not disclosed that the location of the heat absorber solves any stated problem
`
`or is for any particular purpose and it appears that the invention would perform equally well with
`
`heat absorber being located in a bottom portion of the airtight circulation channel.
`
`Regarding claim 11, Takata teaches the liquid crystal display device according to
`
`claim 1, wherein the light source (light source, fig 22, 24) of the backlight (lower
`
`backlight) includes LEDs (col. 21, lines 23—26), and the backlight (lower backlight) further
`
`includes a light source substrate (light source drive circuit, fig 6) on which the LEDs (light
`
`source, fig 22, 24) are disposed (see fig 24).
`
`Regarding claim 12, Takata teaches the liquid crystal display device according to
`
`claim 3, further comprising: a rear frame (back frame, fig 26) disposed behind the
`
`intermediate frame (fig 24; back chassis as described in fig 20) and holding the light
`
`

`

`Application/Control Number: 15/695,701
`Art Unit: 2871
`
`Page 6
`
`source (light source, fig 22), wherein the rear frame (back frame, fig 26) is provided with a
`
`through hole (passage in side walls at end of back frame, fig 24) for communicatively
`
`connecting the first channel (first side channel, figs 24 and 28) and the second channel
`
`(channel for airflow, fig 22 and 24) by cooperating with the through hole (passage in side
`
`walls at end of back frame, fig 24) of the intermediate frame (fig 24; back chassis as
`
`described in fig 20).
`
`Claim 2 is rejected under 35 U.S.C. 103 as being unpatentable over Takata US
`
`7800714 in view of Lee US 2016/0363709.
`
`Regarding claim 2, Takata teaches the liquid crystal display device according to
`
`claim 1, however, does not teach wherein the optical sheet includes a quantum dot film
`
`including quantum dots that convert a wavelength of light emitted by the light source of
`
`the backlight.
`
`Lee teaches wherein the optical sheet (40) includes a quantum dot film (57)
`
`including quantum dots (57) that convert a wavelength of light emitted the light source by
`
`the backlight (51) for the purpose of enabling deep color and high efficiency by providing
`
`displays with an ideal light source.
`
`It would have been obvious to one of ordinary skill
`
`in the art before the effective
`
`filing date of the claimed invention to include the quantum dots film of Lee in the invention
`
`of Takata for the purpose of enabling deep color and high efficiency by providing displays
`
`with an ideal light source.
`
`Claims 4 and 5 are rejected under 35 U.S.C. 103 as being unpatentable over Takata
`
`US 7800714 in view of Na US 2016/0265759.
`
`Regarding claim 4, Takata teaches the liquid crystal display device according to
`
`claim 1, and providing a fan (105) blowing air at the back chassis and also a fan (106)
`
`

`

`Application/Control Number: 15/695,701
`Art Unit: 2871
`
`Page 7
`
`directly blowing air at the second liquid crystal panel, to cool down the entire liquid crystal
`
`display (col 20, lines 5—11). However, Takata does not explicitly teach a fan disposed in the
`
`airtight circulation channel.
`
`Na teaches in fig 3 a fan (50, blower apparatus) disposed in the airtight circulation
`
`channel (circulation channel) for the purpose of further enhancing diffusing heat and
`
`reducing temperature of an internal of a backlight unit ([0012]) for the purpose of further
`
`enhancing diffusing heat and reducing temperature of an internal of a backlight unit
`
`([0012])-
`
`It would have been obvious to one of ordinary skill
`
`in the art before the effective
`
`filing date of the claimed invention to include the fan of Na in the display of Takata for the
`
`purpose of further enhancing diffusing heat and reducing temperature of an internal of a
`
`backlight unit ([0012]).
`
`Regarding claim 5, Takata teaches the liquid crystal display device according to
`
`claim 4, and wherein the fan (105) is proximate to the heat absorber (cooling device; pump
`
`creating circulation of transparent fluid, fig 24) (col 22, lines 17—32).
`
`Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Takata US
`
`7800714 in view of Kang US 2013/0100374.
`
`Regarding claim 6, Takata teaches the liquid crystal display device according to
`
`claim 1, however, does not teach wherein the heat absorber includes heat—absorbing plates,
`
`and two adjacent heat—absorbing plates among the heat—absorbing plates partially define
`
`therebetween the airtight circulation channel.
`
`Kang teaches a heat absorber includes heat—absorbing plates (136), and two adjacent
`
`heat—absorbing plates (136) among the heat—absorbing plates (136) partially define
`
`

`

`Application/Control Number: 15/695,701
`Art Unit: 2871
`
`Page 8
`
`therebetween the airtight circulation channel (ventilation channels, fig 3C) for the purpose
`
`of further increasing the efficiency of the heat absorber ([0038]) for the purpose of further
`
`increasing the efficiency of the heat absorber ([0038]).
`
`It would have been obvious to one of ordinary skill
`
`in the art before the effective
`
`filing date of the claimed invent tion to include the heat—absorbing plates of Kang in the
`
`display of Takata for the purpose of further increasing the efficiency of the heat absorber
`
`([0038])-
