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 9 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Kim as applied to claim 8 or 12 above, and further in view of An et al. (US 2021/0359066 A1; hereinafter “An”)
In regard to claim 9, Kim teaches a second thin-film transistor (an emission control thin film transistor T6) disposed in each of the plurality of sub-pixel areas and including a second semiconductor layer (a semiconductor layer may include channel areas A6) and a second gate electrode (an emission control gate electrode G6) overlapping the second semiconductor layer (Fig. 5A and paragraphs 69 and 108).
However, Kim doesn’t explicitly teach wherein the first semiconductor layer of the first thin-film transistor includes a silicon semiconductor material, and the second semiconductor layer of the second thin-film transistor includes an oxide semiconductor material.
An teaches a display apparatus (a display apparatus as shown in Fig. 1) (Fig. 1 and paragraph 30), wherein the first semiconductor layer of the first thin-film transistor includes a silicon semiconductor material, and the second semiconductor layer of the second thin-film transistor includes an oxide semiconductor material (at least one of the first to seventh transistors T1 to T7 may include a semiconductor layer including an oxide material, and the others include a semiconductor layer including silicon) (Fig. 4 and paragraph 87).
It would have been obvious to one skilled in the art to combine the teachings of Kim with the teachings of An to have the first semiconductor layer of the first thin-film transistor include a silicon semiconductor material, and the second semiconductor layer of the second thin-film transistor include an oxide semiconductor material since this allows the manufacture of a device having transistors with high reliability, and as such, the display apparatus having high resolution may be implemented as taught by An (paragraph 87).
In regard to claim 19, Kim teaches further comprising: a third thin-film transistor (an emission control thin film transistor T6 in pixel PX1) disposed in the first sub-pixel area and including a third semiconductor layer (as shown in Fig. 4 each pixel contains transistors T1-T7 , therefore, a semiconductor layer may include channel areas A6 located in pixel PX1); and a fourth thin-film transistor (an emission control thin film transistor T6 in pixel PX2) disposed in the second sub-pixel area and including a fourth semiconductor layer (as shown in Fig. 4 each pixel contains transistors T1-T7 , therefore, a semiconductor layer may include channel areas A6 located in pixel PX2).
However, Kim doesn’t explicitly teach the first semiconductor layer and the second semiconductor layer include a silicon semiconductor material, and the third semiconductor layer and the fourth semiconductor layer include an oxide semiconductor material.
An teaches a display apparatus (a display apparatus as shown in Fig. 1) (Fig. 1 and paragraph 30), a first semiconductor layer and a second semiconductor layer include a silicon semiconductor material, and the third semiconductor layer and the fourth semiconductor layer include an oxide semiconductor material (a pixel in a left pixel area CA1 and a pixel circuit of a pixel in a right pixel area CA2 may have a symmetrical structure, therefore, both adjacent pixels PX have at least one of the first to seventh transistors T1 to T7 including a semiconductor layer including an oxide material, and the others include a semiconductor layer including silicon) (Fig. 3, Fig. 4 and paragraphs 64, 87 and 90).
It would have been obvious to one skilled in the art to combine the teachings of Kim with the teachings of An to have the first semiconductor layer and the second semiconductor layer include a silicon semiconductor material, and the third semiconductor layer and the fourth semiconductor layer include an oxide semiconductor material since this allows the manufacture of a device having transistors with high reliability, and as such, the display apparatus having high resolution may be implemented as taught by An (paragraph 87).
Claims 10-11 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim as applied to claim 1, 8 or 12 above, and further in view of Park et al. (US 2019/0148476 A1; hereinafter “Park”).
In regard to claim 10, Kim doesn’t explicitly teach wherein the wiring line includes a same material as a material of the electrode.
Park teaches a display apparatus (a display device as shown in Fig. 1) (Fig. 1 and paragraph 28), wherein a wiring line (a first connection wiring 140) includes a same material as a material of an electrode (the first connection wiring 140 and a second electrode C2 of the storage capacitor Cst both contain titanium (Ti)) (Fig. 10 and paragraphs 100 and 128).
It would have been obvious to one skilled in the art to combine the teachings of Kim with the teachings of Park to have the wiring line include a same material as a material of the electrode since it is well known that conductive material is needed for proper device operation further it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416.
In regard to claim 11, Kim teaches wherein the display apparatus includes a display area (a display area DA) including the plurality of sub-pixel areas (the display area DA and includes a plurality of pixels PX) (Fig. 1 and paragraph 54).
However, Kim doesn’t explicitly teach wherein the display area is foldable or rollable.
Park teaches wherein a display area is foldable or rollable (the display area DA is foldable or rollable as illustrated in FIGS. 18 and 19) (Fig. 18, Fig. 19 and paragraph 198).
It would have been obvious to one skilled in the art at the time to combine the teachings of Kim with the teachings of Park to have a display area is foldable or rollable since the likelihood of the occurrence of a crack will be reduced as taught by Park (paragraph 200).
In regard to claim 20, Kim teaches an electrode (a second electrode Cst2) overlapping and electrically connected to one of a source region (a driving source electrode S1) and a drain region (a driving drain electrode D1) of the first semiconductor layer in the plan view (the second electrode Cst2 overlaps the driving source electrode S1 and is electrically connected to the driving source electrode S1 through the driving voltage line 152) (Fig. 3, Fig. 5A and paragraphs 69 and 125).
Kim doesn’t explicitly teach wherein the wiring line includes a same material as a material of the electrode.
Park teaches a display apparatus (a display device as shown in Fig. 1) (Fig. 1 and paragraph 28), wherein a wiring line (a first connection wiring 140) includes a same material as a material of an electrode (the first connection wiring 140 and a second electrode C2 of the storage capacitor Cst both contain titanium (Ti)) (Fig. 10 and paragraphs 100 and 128).
It would have been obvious to one skilled in the art to combine the teachings of Kim with the teachings of Park to have the wiring line include a same material as a material of the electrode since it is well known that conductive material is needed for proper device operation further it has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice.
