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 .
Specification
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. If Applicant fails to provide a sufficiently descriptive title, Examiner will do so upon allowance of the claims.
Claim Objections
Claims 2 and 12 are objected to because of the following informalities: Claims 2 and 12 recite “wherein an operating power of the second light source group to be less than”. Examiner assumes this is a typographical error and Applicant intended to claim “wherein an operating power of the second light source group is less than”. Appropriate correction is required.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-3, 6-8, 11-13, and 16-18 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Dunn (US 2012/0147293).

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.
Claims 4 and 14 are rejected under 35 U.S.C. 103 as being unpatentable over Dunn in view of Kim et al. (US 2004/0174332).
Regarding claim 4, Dunn fails to explicitly disclose wherein the current sensing element comprises resistance detection type sensing elements and magnetic field detection type sensing elements.
However, Examiner takes official notice that the use of resistance detection type sensing elements for current sensing is well known in the art. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the device of Dunn with the well-known resistance detection type sensing elements since such a modification achieves the predictable result of accurately measuring current with conventional sensors.
Kim teaches magnetic field detection type sensing elements (abstract, figs. 1-4, ¶ 47-51, electromagnetic induction sensors disclosed, see also ¶ 101).
Dunn and Kim are both directed to sensors for detecting a backlight malfunction. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the device of Dunn with the device of Kim since such a modification prevents deterioration of the lamps and increases the life expectancy of the lamps (Kim, abstract, ¶ 11).
Regarding claim 14, this claim is rejected under the same rationale as claim 4.
Claims 5 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Dunn in view of Price et al. (US 2008/0100561).
Regarding claim 5, Dunn fails to explicitly disclose wherein the sensing unit comprises a voltage sensing element, the voltage sensing element is configured to detect whether a voltage of the first light source group is greater than a preset voltage range, when the voltage sensing element detects the voltage of the first light source group is greater than the preset voltage range, the first light source group is determined to be abnormal.
Price teaches wherein the sensing unit comprises a voltage sensing element, the voltage sensing element is configured to detect whether a voltage of the first light source group is greater than a preset voltage range, when the voltage sensing element detects the voltage of the first light source group is greater than the preset voltage range, the first light source group is determined to be abnormal (abstract, fig. 2, ¶ 16-18, voltage measured to identify faults, e.g., an increased termination voltage indicates a short in an LED with the number of shorts determined by the excess voltage).
Dunn and Price are both directed to sensors for detecting a backlight malfunction. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the device of Dunn with the device of Price since such a modification manages LED backlight performance (Price, ¶ 7) and provides failure of one or more LEDs is automatically compensated (Price, ¶ 8).
Regarding claim 15, this claim is rejected under the same rationale as claim 5.
Claims 9-10 and 19-20 are rejected under 35 U.S.C. 103 as being unpatentable over Dunn in view of Cheang et al. (US 2005/0242742).
Regarding claim 9, Dunn discloses wherein when the first light source group and the second light source group are arranged outside of the active area of the display panel (figs. 1-3, ¶ 20-28, edge-lit embodiments disclosed).
Dunn fails to explicitly disclose the display system comprises a switching unit and a driving integrated circuit, the driving integrated circuit is connected to the first light source group or the second light source group through the switching unit, when the first light source group has no abnormality, the control unit controls the switching unit to be connected to the first light source group to supply power to the first light source group, when the first light source group is abnormal, the control unit controls the switching unit to be connected to the second light source group to supply power to the second light source group.
Cheang teaches the display system comprises a switching unit and a driving integrated circuit, the driving integrated circuit is connected to the first light source group or the second light source group through the switching unit (abstract, figs. 2-3, ¶ 15-20, redundant light source management system 110 uses to feedback to determine when to activate redundant light source; see also ¶ 23-28, switch system 118 disclosed; activating only one light source at a time is possible),
when the first light source group has no abnormality, the control unit controls the switching unit to be connected to the first light source group to supply power to the first light source group, when the first light source group is abnormal, the control unit controls the switching unit to be connected to the second light source group to supply power to the second light source group (abstract, figs. 2-3, ¶ 15-20, redundant light source management system 110 uses to feedback to determine when to activate redundant light source; see also ¶ 23-28, switch system 118 disclosed; activating only one light source at a time is possible).
Dunn and Cheang are both directed to sensors for detecting a backlight malfunction. Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to combine the device of Dunn with the device of Cheang since such a modification produces light of a desired quality for longer (Cheang, ¶ 3) to extend the life of the system (Cheang, ¶ 4).
Regarding claim 10, Dunn discloses wherein the sensing unit is arranged on the driving integrated circuit, the driving integrated circuit is configured to provide working current to the first light source group (fig. 4, ¶ 29, controllers 515 and 530 may be any type of application-specific integrated circuit).
Regarding claim 19, this claim is rejected under the same rationale as claim 9.
Regarding claim 20, this claim is rejected under the same rationale as claim 10.
