Claim Rejections - 35 USC § 103
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 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 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Jung, US PGPUB 20200326752 in view of Tanaka et al., US PGPUB 20020093473 hereinafter referenced as Tanaka.
As to claim 1, Jung discloses an electronic device comprising: at least one processor comprising processing circuitry; display driver circuitry including a graphic random access memory (GRAM) ([0132] In an exemplary embodiment, the sum SUM calculated from the partial display mode (i.e., the second display mode MODE2 or the third display mode MODE3) may be stored and updated for each of the first and second display areas AA1 and AA2 in a separate memory device, for example); and
a display panel, wherein the display driver circuitry is configured to: change an image stored in the GRAM from a first image to a second image, the first image being provided from the at least one processor in a first time interval in response to a synchronization signal from the display driver circuitry and the second image being provided from the at least one processor in a second time interval subsequent to the first time interval in response to the synchronization signal ([0076] he timing controller 280 may convert input image data (e.g., the first image data DATA1) provided from the processor 300, and provide converted image data DATA1′ to the data driver 260);
on a condition that a time length between a start timing of a last scanning of the first image stored in the GRAM executed in the first time interval and a start timing of an initial scanning of the second image stored in the GRAM is longer than or equal to a reference length, display, on the display panel, the second image, based on executing multiple scans of the second image stored in the GRAM in the second time interval ([0190] the determinator 222 may change a setting value of the area selection signal SEL to another setting value when the change value DIFF exceeds the second reference value (e.g., determine whether the second image data DATA2 having the same pattern continues for a predetermined time or longer)).
Jung does not specifically disclose on a condition that the time length is shorter than the reference length, display, on the display panel, the second image, based on executing a single scan of the second image stored in the GRAM in the second time interval.
However, in the same endeavor, Tanaka discloses on a condition that the time length is shorter than the reference length, display, on the display panel, the second image, based on executing a single scan of the second image stored in the GRAM in the second time interval ([0030] Therefore, the screen is scanned only once in a normal situation, that is, when there is no change in an image to be displayed, and the screen scan is repeated twice or more and only when the display is switched, that is, when there has been a change in an image to be displayed).
Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Jung to further include Tanaka’s scanning method, in order to reduce the power consumption of the device.
As to claim 15, Jung discloses an electronic device comprising: at least one processor comprising processing circuitry; display driver circuitry including a graphic random access memory (GRAM) ([0132] In an exemplary embodiment, the sum SUM calculated from the partial display mode (i.e., the second display mode MODE2 or the third display mode MODE3) may be stored and updated for each of the first and second display areas AA1 and AA2 in a separate memory device, for example); and
a display panel, wherein the display driver circuitry is configured to: change an image stored in the GRAM, from a first image to a second image ([0076] he timing controller 280 may convert input image data (e.g., the first image data DATA1) provided from the processor 300, and provide converted image data DATA1′ to the data driver 260),
the first image being provided from the at least one processor in a first time interval in response to a synchronization signal from the display driver circuitry and the second image being provided from the at least one processor in a second time interval subsequent to the first time interval in response to the synchronization signal ([0147] since the first display area AA1 exceeds the first reference value to be relatively more degraded in the first interval between the first time T1 and the second time T2, the first reference value in the second interval between the third time T3 and the fourth time T4 may become greater so as to match the degree of degradation of the second display area AA2 with the degree of degradation of the first display area AA1);
on a condition that a single scan of the first image stored in the GRAM is executed within the first time interval for displaying of the first image, display, on the display panel, the second image, based on executing multiple scans of the second image stored in the GRAM within the second time interval ([0187] In an exemplary embodiment, in the method of FIG. 12, when the display panel 100 is in an unfolded state, the display device 1000 may be driven in the full display mode (i.e., the first display mode) and generate the first image data DATA1 (i.e., an input image data corresponding to the first and second display areas AA1 and AA2 of the display panel 100) through the processor 300, for example); and
on a condition that multiple scans of the first image stored in the GRAM are executed within the first time interval for displaying of the first image, display, on the display panel, the second image, based on executing a single scan of the second image stored in the GRAM within the second time interval ([0080] In this case, the data driver 260 may generate the data signal DS corresponding to the second display area AA2 based on the converted second image data DATA2′, and the display panel 100 may display an image corresponding to the converted second image data DATA2′ in the second display area AA2.

Therefore, it would have been obvious to one of ordinary skill in the art to modify the disclosure of Jung to further include Tanaka’s scanning method, in order to reduce the power consumption of the device.
