Office Action

§103
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 . Response to Arguments Applicant’s arguments with respect to claim(s) 1 and 15 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. Allowable Subject Matter Claim 9 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The primary reason for the allowance of the claims is the inclusion of the limitation, along with the other claimed features, “wherein every two adjacent ones of the cathodes are provided with one of the touch bonding portions therebetween, some of the touch bonding portions are arranged on hollow portions, and each of the hollow portions is arranged between one of the cathodes and one of the touch electrodes”, as recited in claim 9. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 1-8, 10, 12-15, and 21-25 are rejected under 35 U.S.C. 103 as being unpatentable over Feng (U.S. 2019/0386069 A1, hereinafter refer to Feng) in view of Lee et al. (U.S. 2018/0143729 A1, hereinafter refer to Lee). Regarding Claim 1: Feng discloses a array substrate (see Feng, Figs.1-3 as shown below and ¶ [0002]), comprising: PNG media_image1.png 311 606 media_image1.png Greyscale PNG media_image2.png 448 628 media_image2.png Greyscale PNG media_image3.png 667 563 media_image3.png Greyscale a base (100) (see Feng, Fig.1 as shown above); an intermediate layer (200), disposed on the base (100) and comprising a plurality of pixel units (300) (see Feng, Fig.1 as shown above); and a cathode layer (800), disposed on a side of the intermediate layer (200) away from the base (100), comprising touch electrodes (600), and comprising cathodes (800) corresponding to the pixel units (300) (see Feng, Fig.1 as shown above), wherein a vertical orthographic projection of each of the cathodes (800) on the base (100) covers vertical orthographic projections of two of the pixel units (300) on the base (100) (see Feng, Figs.1-3 as shown above and ¶ [0033]), and each of the touch electrodes (600) is spaced apart from one of the cathodes (800) (see Feng, Fig.1 as shown above). Feng is silent upon explicitly disclosing a plan view wherein each of the touch electrodes surrounds one of the cathodes. For support see Lee, which teaches a plan view wherein each of the touch electrodes (223) surrounds one of the cathodes (210) (note: the top or plan view of Fig.8 of Lee necessarily results the each of the touch electrodes (223) surrounds one of the cathodes corresponding to the pixel units (221)) (see Lee, Fig.2 and 8 as shown below and ¶ [0006]). PNG media_image4.png 308 667 media_image4.png Greyscale PNG media_image5.png 449 636 media_image5.png Greyscale Thus, it would have been obvious to one of ordinary skill in the art before effective filing date of the claimed invention to combine the teachings of Feng and Lee to enable the Feng touch electrodes to surround one of the cathodes corresponding to the pixel units as taught by Lee in order to obtain an OLED display panel with touch sensing electrodes to mitigate and/or obviate the aforementioned problems. Regarding Claim 2: Feng as modified teaches a array substrate as set forth in claim 1 as above.

Regarding Claim 5: Feng as modified teaches a array substrate as set forth in claim 3 as above. The combination of Feng and Lee further teaches wherein the cathode layer (800) further comprises hollow portions (note: the space between cathode layer 800 and touch electrode layer 600 is equivalent to the claimed limitation of “hollow portions”) disposed between the cathodes (800) and the touch electrodes (600) (see Feng, Figs.1 and 3 as shown above); each of the hollow portions surrounds one of the cathodes (800) and is surrounded by one of the touch electrodes (600) (see Feng, Figs.1 and 3 as shown above); and some of the cathode bonding portions (note: edge of cathode layer 800 which is close to the space between cathode layer 800 and touch electrode 600 is considered as equivalent to the claimed limitation of “cathode bonding portions”) are arranged on the hollow portions and spaced apart from the touch electrodes (600) (see Feng, Figs.1 and 3 as shown above). Regarding Claim 6: Feng as modified teaches a array substrate as set forth in claim 3 as above. The combination of Feng and Lee further teaches wherein the cathode layer (800) further comprises hollow portions (note: the space between cathode layer 800 and touch electrode layer 600 is equivalent to the claimed limitation of “hollow portions”) disposed between the cathodes (800) and the touch electrodes (600) (see Feng, Fig.1 as shown above); each of the hollow portions surrounds one of the cathodes (800) and is surrounded by one of the touch electrodes (600) (see Feng, Fig.1 as shown above); and some of the touch bonding portions (612) (note: edge of touch electrode 600 which is close to the space between cathode layer 800 and touch electrode 600 is considered as equivalent to the claimed limitation of “touch bonding portions/612”) are arranged on the hollow portions and spaced apart from the cathodes (800) (see Feng, Figs.1 and 3 as shown above). Regarding Claim 7: Feng as modified teaches a array substrate as set forth in claim 3 as above. The combination of Feng and Lee further teaches wherein the cathode layer further comprises hollow portions (note: the space between cathode layer 800 and touch electrode layer 600 is equivalent to the claimed limitation of “hollow portions”) disposed between the cathodes (800) and the touch electrodes (600) (see Feng, Fig.1 as shown above); each of the hollow portions surrounds one of the cathodes (800) and is surrounded by one of the touch electrodes (600) (see Feng, Fig.1 as shown above); some of the cathode bonding portions (note: edge of cathode layer 800 which is close to the space between cathode layer 800 and touch electrode 600 is considered as equivalent to the claimed limitation of “cathode bonding portions”) are arranged on the hollow portions and spaced apart from the touch electrodes (600) (see Feng, Figs.1 and 3 as shown above); and some of the touch bonding portions (612) (note: edge of touch electrode 600 which is close to the space between cathode layer 800 and touch electrode 600 is considered as equivalent to the claimed limitation of “touch bonding portions/612”) are arranged on the hollow portions and spaced apart from the cathodes (800) (see Feng, Figs.1 and 3 as shown above). Regarding Claim 8: Feng as modified teaches a array substrate as set forth in claim 3 as above. The combination of Feng and Lee further teaches wherein some of the cathodes (210) are not provided with the touch bonding portions therebetween (see Lee, Fig.2 and 8 as shown above). Regarding Claim 10: Feng as modified teaches a array substrate as set forth in claim 3 as above. The combination of Feng and Lee further teaches wherein some of the cathode bonding portions and some of the touch bonding portions are alternately arranged along the second direction (see Lee, Fig.2 and 8 as shown above).

Regarding Claim 13: Feng as modified teaches a array substrate as set forth in claim 1 as above. The combination of Feng and Lee further teaches wherein a cross-sectional shape of each of the cathodes (800) is a regular quadrilateral (see Feng, Figs.1-3 as shown above). Regarding Claim 14: Feng as modified teaches a array substrate as set forth in claim 1 as above. The combination of Feng and Lee further teaches wherein a cross-sectional shape of each of the cathodes (800) is an irregular polygon, and each of the cathodes (800) correspondingly covers light-emitting units (700) of the pixel units (300) and covers a part of a gap between the pixel units (300) (see Feng, Figs.1-3 as shown above). Regarding Claim 15: Feng discloses a display panel, comprising an array substrate (see Feng, Figs.1-3 as shown above and ¶ [0002]), wherein the array substrate comprises: a base (100) (see Feng, Fig.1 as shown above); an intermediate layer (200), disposed on the base (100) and comprising a plurality of pixel units (300) (see Feng, Fig.1 as shown above); and a cathode layer (800), disposed on a side of the intermediate layer (200) away from the base (100), comprising touch electrodes (600), and comprising cathodes (800) corresponding to the pixel units (300) (see Feng, Figs.1-3 as shown above), wherein a vertical orthographic projection of each of the cathodes (800) on the base (100) covers vertical orthographic projections of two of the pixel units (300) on the base (100), and is spaced apart from one of the cathodes (800) (see Feng, Fig.1 as shown above and ¶ [0033]).

Regarding Claim 25: Feng as modified teaches an array substrate as set forth in claim 23 as above. The combination of Feng and Lee further teaches wherein every two adjacent ones of the cathodes (800) are provided with a corresponding one of the touch bonding portions (612) therebetween, some of the touch bonding portions (612) are arranged on hollow portions (note: the space between cathode layer 800 and touch electrode layer 600 is equivalent to the claimed limitation of “hollow portions”), and each of the hollow portions is arranged between a corresponding one of the cathodes (800) and a corresponding one of the touch electrodes (600) (see Feng, Figs.1 and 3 as shown above). Claim(s) 11 is rejected under 35 U.S.C. 103 as being unpatentable over Feng (U.S. 2019/0386069 A1, hereinafter refer to Feng) and Lee et al. (U.S. 2018/0143729 A1, hereinafter refer to Lee) as applied to claim 1 above, and further in view of Kim et al. (U.S. 2024/0224660 A1, hereinafter refer to Kim). Regarding Claim 11: Feng as modified teaches a array substrate as set forth in claim 3 as above; however, The combination of Feng and Lee is silent upon explicitly disclosing wherein materials of the cathodes and the touch electrodes all comprise magnesium-silver alloy. For support see Kim, which teaches wherein materials of the cathodes and the touch electrodes all comprise magnesium-silver alloy (see Kim, ¶ [0120]). Feng discloses the claimed invention except for the materials of the cathodes and the touch electrodes. Thus, it would have been obvious to one having ordinary skill in the art before effective filing date of the claimed invention to combine the teachings of Feng, Lee, and Kim to enable the known material for forming the cathodes and the touch electrodes layers as taught by Kim increase light emitting efficiency, since it has been held to be within the general skill of a worker in the art to select a known material on the base of its suitability, for its intended use involves only ordinary skill in the art.
