`
`DETAILED ACTION
`
`Specification
`
`1.
`
`The title of the invention is not descriptive. A new title is required that is clearly indicative of the
`
`invention to which the claims are directed.
`
`The following title is suggested: “Liquid Crystal Display Device with White Point Correction”.
`
`Claim Objections
`
`2.
`
`Claims 3 and 7 are objected to because of the following informalities:
`
`Regarding claim 7, On pg. 24, line 8 in claim 7 "the liquid crystal display device" is referenced
`
`when only a "liquid crystal display panel" was previously mentioned. Considering claim 1, it was likely
`
`meant the first instance of "a liquid crystal display panel" on pg. 23, line 22 was meant to be "a liquid
`
`crystal display device".
`
`Regarding claim 3, a group of claim elements (“the light guide panel, the light emitting diodes,
`
`and the flexible circuit substrate” are described as being both “housed in a frame” and being mounted on
`
`the surface of same said frame. The previous term suggests those components would be internal to the
`
`frame while the latter suggests that external but in direct contact. For the purposes of examination, it will
`
`be assumed they are mounted.
`
`Appropriate correction is required.
`
`Claim Rejections - 35 USC § 103
`
`3.
`
`The following is a quotation of 35 U.S.C. 103(a) which forms the basis for all obviousness
`
`rejections set forth in this Office action:

`
`(a) A patent may not be obtained though the invention is not identically disclosed or described as set
`forth in section 102 of this title, if the differences between the subject matter sought to be patented and
`the prior art are such that the subject matter as a whole would have been obvious at the time the
`invention was made to a person having ordinary skill in the art to which said subject matter pertains.
`Patentability shall not be negatived by the manner in which the invention was made.
`
`4.
`
`Claims 1, 7, and 9-11 are rejected under 35 U.S.C. 103(a) as being unpatentable over Myers
`
`(US 20100073390 A1) in view of Morimoto et al. (US 20080245949 A1, hereafter Morimoto).
`
`Regarding claim 1, Myers teaches a liquid crystal display device comprising a liquid crystal
`
`display panel to which an image signal is input, and a backlight provided on one side of the liquid crystal
`
`display panel (Fig. 1, [0010], where the display panel 24 comprises a LCD panel, receives image signals
`
`23, and also comprises a backlight),
`
`wherein information about white tolerance of the light source using the light emitting diode,
`
`indicating one rank of a plurality of ranks assigned to the white tolerance (Fig. 2, [0022], where the EDID
`
`information stored in storage 30 contains information derived from calculations about response curves or
`
`ranks for color information and white point error),
`
`the liquid crystal display device further comprises an image quality processing circuit to which the
`
`information stored in the memory device can be input in order to correct gamma characteristics of the
`
`image signal according to the information (Figs. 2, where method described in [0022] at step 112 involves
`
`generating correction values based upon the calculated values for compensating for white point error
`
`using the scaler/controller 22).
`
`But, Myers does not teach the liquid crystal display device where a light emitting diode is used as
`
`a light source of the backlight and wherein information about the white tolerance of the light source using
`
`the light emitting diode is indicated in a portion of the backlight.
`
`However, this was well known in the art as evidenced by Morimoto (Figs. 3 and 4, [0093]—[0095],
`
`where there are LEDs R, G, and B and where there is a memory 51 e on substrate on the backside of the
`
`substrate with the LEDs that possesses reference information for corrective values). It would have been
`
`obvious to one of ordinary skill in the art at the time of the invention to adapt the backlight of Myers which
`
`

`

`Application/Control Number: 12/699,117
`
`Art Unit: 2692
`
`Page 4
`
`already addresses separate RGB light sources (Myers [0019]) to use light emitting diodes as a standard
`
`choice as suggested by Morimoto. Additionally, the placement of storage of corrective information relating
`
`to the backlight on a structure integral to the backlight enables easy manufacture and factory calibration
`
`of backlight units as well as future easy retrieval and updating of the factory default information.
`
`Regarding claim 7, Myers teaches a liquid crystal display panel comprising a liquid crystal
`
`display panel to which an image signal is input, and a backlight provided on one side of the liquid crystal
`
`display panel (Fig. 1, [0010], where the display panel 24 comprises a LCD panel, receives image signals
`
`23, and also comprises a backlight),
`
`wherein information about white tolerance of the light source using the light emitting diode,
`
`indicating one rank of a plurality of ranks assigned to the white tolerance, is stored in a memory device
`
`(Fig. 2, [0022], where the EDID information stored in storage 30 contains information derived from
`
`calculations about response curves or ranks for color information and white point error),
`
`the liquid crystal display device further comprises an image quality processing circuit to which the
`
`information stored in the memory device can be input in order to correct gamma characteristics of the
`
`image signal according to the information (Figs. 2, where method described in [0022] at step 112 involves
`
`generating correction values based upon the calculated values for compensating for white point error
`
`using the scaler/controller 22).
`
`But, Myers does not teach the liquid crystal display device where a light emitting diode is used as
`
`a light source of the backlight and wherein the memory device containing information about the white
`
`tolerance of the light source using the light emitting diode is located in a portion of the backlight.
`
`However, this was well known in the art as evidenced by Morimoto (Figs. 3 and 4, [0093]-[0095],
`
`where there are LEDs R, G, and B and where there is a memory 51 e on substrate on the backside of the
`
`substrate with the LEDs that possesses reference information for corrective values). It would have been
`
`obvious to one of ordinary skill in the art at the time of the invention to adapt the backlight of Myers which
`
`already addresses separate RGB light sources (Myers [0019]) to use light emitting diodes as a standard
`
`choice as suggested by Morimoto. Additionally, the placement of storage of corrective information relating
`
`

`

`Application/Control Number: 12/699,117
`
`Art Unit: 2692
`
`Page 5
`
`to the backlight on a structure integral to the backlight enables easy manufacture and factory calibration
`
`of backlight units as well as future easy retrieval and updating of the factory default information.
`
`Regarding claim 9, the combination of Myers and Morimoto would show the liquid crystal display
`
`device of claim 7. Myers further teaches the liquid crystal display device wherein the memory device is
`
`electrically coupled to the image quality processing circuit, so that the information stored in the memory
`
`device can be output to the image quality processing circuit (Fig. 1, [0024], where scaler/controller 22 and
`
`storage 30 are connected and information passes from the storage to the scaler/controller 22 and further
`
`on to the host computer 10).
`
`Regarding claim 10, the combination of Myers and Morimoto would show the liquid crystal
`
`display device of claim 1. Morimoto in the combination teaches the liquid crystal display device wherein
`
`the backlight includes a plurality of light emitting diodes dispersed on a surface facing the liquid crystal
`
`display panel (Fig. 4, where the LEDs R, G, and B are dispersed on the substrate and act a backlight for
`
`the liquid crystal unit 2 as shown in Fig. 1b).
`
`Regarding claim 11, the combination of Myers and Morimoto would show the liquid crystal
`
`display device of claim 7. Morimoto in the combination teaches the liquid crystal display device wherein
`
`the backlight includes a plurality of light emitting diodes dispersed on a surface facing the liquid crystal
`
`display panel (Fig. 4, where the LEDs R, G, and B are dispersed on the substrate and act a backlight for
`
`the liquid crystal unit 2 as shown in Fig. 1b).
`
`5.
`
`Claim 2, 3, 6, and 8 are rejected under 35 U.S.C. 103(a) as being unpatentable over Myers
`
`(US 20100073390 A1) in view of Morimoto et al. (US 20080245949 A1, hereafter Morimoto) and
`
`further in view of Bulovic et al. (US 20050088380 A1, hereafter Bulovic).
`
`

`

`Application/Control Number: 12/699,117
`
`Art Unit: 2692
`
`Page 6
`
`Regarding claim 2, the combination of Myers and Morimoto would show the liquid crystal display
`
`device according to claim 1. Morimoto in the combination teaches the liquid crystal display device
`
`according to claim 1 wherein the information indicating the rank of the white tolerance of the light source
`
`using the light emitting diodes is clearly indicated in the circuit substrate (Fig. 3, where corrective data is
`
`stored in the circuit substrate at 51 e).
`
`But, the combination does not teach the liquid crystal display device wherein the backlight
`
`includes at least a light guide panel provided to face the liquid crystal display panel, and a plurality of light
`
`emitting diodes arranged in parallel on a flexible circuit substrate so that the plurality of light emitting
`
`diodes face at least one side of a side wall surface of the light guide panel.
`
`However, this was well known in the art as evidenced by Bulovic (Fig. 1, [0017], where the
`
`substrate 110 also acts as a light guide panel and LEDs disposed on the substrate are facing it). Both
`
`Myers and Bulovic are directed towards the compensation of defects in, among other things, backlighting
`
`using LED arrays. It would have been obvious to one of ordinary skill in the art at the time of the invention
`
`to substitute a flexible substrate for a standard substrate as taught by Bulovic in the liquid crystal panel of
`
`Myers and Morimoto to make the device lightweight.
`
`Regarding claim 3, the combination of Myers, Morimoto, and Bulovic would show the liquid
`
`crystal display device according to claim 2. Morimoto in the combination further teaches wherein the light
`
`guide panel, the light emitting didoes, and the flexible circuit substrate are housed in a frame (Fig. 4,
`
`where the components are a part of substrate 31 on frame 4),
`
`the frame includes a control circuit substrate for driving the light emitting didoes through the
`
`flexible circuit substrate, which is provided on a surface of the frame opposite to a surface on which the
`
`light guide panel, the light emitting didoes, and the flexible circuit substrate are mounted (Fig. 4, [0089],
`
`where the other section 51 of the substrate on the opposite side of frame 4 comprises the driving
`
`circuitry),
`
`an end of the flexible circuit substrate is electrically coupled to the control circuit substrate
`
`through a connector, and the information indicating the rank of the white tolerance of the light source
`
`

`

`Application/Control Number: 12/699,117
`
`Art Unit: 2692
`
`Page 7
`
`using the light emitting diodes is clearly indicated in a portion adjacent to the connector of the flexible
`
`circuit substrate (Fig. 4, where there are the driving current and intensity signal connections).
`
`Regarding claim 6, the combination of Myers, Morimoto, and Bulovic would show the liquid
`
`crystal display device of claim 3. Morimoto in the combination teaches the liquid crystal display device
`
`wherein the information indicating the rank of the white tolerance of the light source using the light
`
`emitting diodes, is displayed at least on one of a front surface and a back surface of the flexible circuit
`
`substrate (Figs. 3 and 4, where the memory 51 e containing reference corrective data is located on the
`
`back surface).
`
`Regarding claim 8, the combination of Myers and Morimoto, would show the liquid crystal
`
`display device according to claim 7. But the combiantion does not teach the liquid crystal display device
`
`wherein the backlight includes at least a light guide panel provided to face the liquid crystal display panel,
`
`a plurality of light emitting didoes provided to face a side wall surface of the light guide panel, and a
`
`flexible circuit substrate on which the plurality of light emitting diodes are mounted.
`
`However, this was well known in the art as evidenced by Bulovic (Fig. 1, [0017], where the
`
`substrate 110 also acts as a light guide panel and LEDs disposed on the substrate are facing it). Both
`
`Myers and Bulovic are directed towards the compensation of defects in, among other things, backlighting
`
`using LED arrays. It would have been obvious to one of ordinary skill in the art at the time of the invention
`
`to substitute a flexible substrate for a standard substrate as taught by Bulovic in the liquid crystal panel of
`
`Myers and Morimoto to make the device lightweight.
`
`Morimoto in the combination further teaches the liquid crystal display device wherein the memory
`
`device is mounted on the flexible circuit substrate (Fig. 3, [0082], where the pixel 31 and memory circuits
`
`51 are both mounted to a substrate comprising the backlight unit 71).
`

`Application/Control Number: 12/699,117
`
`Art Unit: 2692
`

`
`6.
`
`Claim 4 is rejected under 35 U.S.C. 103(a) as being unpatentable over Myers (US
`
`20100073390 A1) in view of Morimoto et al. (US 20080245949 A1, hereafter Morimoto) and further
`
`in view of Bulovic et al. (US 20050088380 A1, hereafter Bulovic) and Liu et al. (US 20100033109 A1,
`
`hereafter Liu).
`
`Regarding claim 4, the combination of Myers, Morimoto, and Bulovic would show the liquid
`
`crystal display device of claim 3. But, the combination does not teach the liquid crystal display device
`
`wherein the information indicating the rank of the white tolerance of the light source using the light
`
`emitting diodes, is clearly indicated by means of a dummy resistance attached to the flexible circuit
`
`substrate.
`
`However, this was well known in the art as evidenced by Liu (Fig. 5, [0030], where the forward
`
`voltage expressed across the voltage divider including RSENJ has information conveys information about
`
`the LED).
`
`It would have been obvious to one of ordinary skill in the art at the time of the invention to
`
`gather information about the LED strings found in the backlight of the liquid crystal display device of
`
`Myers, Morimoto, and Bulovic using a resistance such as taught by Liu to precisely and electrically gather
`
`data about current state of the LED strings.
`
`7.
`
`Claim 5 is rejected under 35 U.S.C. 103(a) as being unpatentable over Myers (US
`
`20100073390 A1) in view of Morimoto et al. (US 20080245949 A1, hereafter Morimoto) and further
`
`in view of Bulovic et al. (US 20050088380 A1, hereafter Bulovic) and Tseng (US 20080307200 A1).
`
`Regarding claim 5, the combination of Myers, Morimoto, and Bulovic would show the liquid
`
`crystal display device of claim 3. But, the combination does not teach the liquid crystal display device
`
`wherein the information indicating the rank of the white tolerance of the light source using the light
`
`emitting diodes, is clearly indicated by means of a bar code printed on the flexible circuit substrate.
`
`However, this was well known in the art as evidenced by Tseng (Fig. 3, [0025], where a bar code
`
`is burned to the display device; [0004], where this bar code may include color information of the device). It
`
`

`

`Application/Control Number: 12/699,117
`
`Art Unit: 2692
`
`Page 9
`
`would have been obvious to one of ordinary skill in the art at the time of the invention to use a bar code to
`
`transfer initial gamma characteristics of the display device as taught by Tseng and capture this
`
`information as the initial panel data for storage in a memory device manufactured separate from the
`
`backlight components. Such an arrangement would provide an easy set of initial values for usage in the
`
`image processing circuit.
