Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Chang in view of Jones et al., with the teachings of Son et al., the motivation being to control one or both displays to output individually or simultaneously a screen according to the coupling form of the two display devices, thereby improving user’s experience convenience and usability of the electronic devices. As to Claim 3, Chang in view of Jones et al., as modified by Son et al., disclose wherein the second content image is a partial image of the first content image (Son-fig.7 (705), para.0108). As to Claim 4, Chang in view of Jones et al., as modified by Son et al., disclose wherein the first display device determines whether the second display device is attached by detecting magnetic force between a first magnet provided on one surface of the first display device and a second magnet provided on one surface of the second display device (Son-para.0063, 0068-0069). As to Claim 6, Chang in view of Jones et al. as modified by Son et al. disclose wherein when the second display device is detached from the first display device, the second display device displays the second content image (Jones-para. 0053, 0070; Son-para.0059, 0063) Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chang (US 2010/0124006) in view of Jones et al. (US 2011/0230178), further in view of Son et al. (US 2019/0004764), and further in view of Kim et al. (US 2015/0317120). As to Claim 2, Chang in view of Jones et al., as modified by Son et al. disclose wherein a screen of the first display device is larger than a screen of the second display device (Chang-fig.12, display panel 32 is larger than display panel 42). Chang in view of Jones as modified by Son et al. do not expressly disclose wherein the second content image is an enlarged image of the first content image. Kim et al. discloses a second display displaying second content image that is an enlarged image of a first content image (fig.11, display 1110A displays an enlarged image of a thumbnail of display 1120A; fig.11B; fig.12A, display 1220A displays enlarged image 1221A of image content 1211A of display 1210A; para.0119,0191,0201). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the device disclosed by Chang in view of Jones et al., with the teachings of Kim et al., the motivation being to output content on one or more displays and outputting menus or information associated with any other display.
