Abstract: An electronic device and a method for controlling the electronic device are provided. The electronic device includes a substantially circular or oval display, a processor configured to generate content, a display driving unit comprising display driving circuitry including a first driver and a second driver, wherein the display driving unit is configured to control driving of the display, to identify a shape of an area of content which is displayed in the display, to identify the shape of the display, to determine a first area of the display in which the content is to be displayed, to determine a second area of the display in which the content is not to be displayed based on at least a result of the identification, to deactivate at least part of the display driving unit, corresponding to the second area, while activating the display driving unit corresponding to the first area.

Abstract: An electronic device includes a display panel, a gamma circuit, a driving circuit, and a fingerprint recognition sensor. The gamma circuit generates a first set of gray voltages in a normal operation mode and a fingerprint recognition voltage corresponding to a brightness higher than a maximum gray voltage among the first set of gray voltages. The driving circuit displays an image on the display panel based on the first set of gray voltages in the normal operation mode and a fingerprint recognition window on a portion of the display panel based on the fingerprint recognition voltage in the fingerprint recognition mode. The fingerprint recognition sensor recognizes a fingerprint based on reflected light of the fingerprint received through the fingerprint recognition window.

Abstract: A flexible display device includes a flexible display panel, a flexible printed circuit board extending from the display panel, an integrated circuit chip that is mounted on at least one surface of the flexible printed circuit board and is configured to drive the display panel, and a protection member attached to a rear surface of the display panel. When the flexible printed circuit board is flexed to be partially positioned on the rear surface of the display panel, the protection member is positioned between the display panel and the integrated circuit chip. The flexible display device prevents the integrated circuit chip stacked with the display panel from making direct contact with the display panel using the protection member. Thus, even if the display device is deformed into, for example, a flexed or rolled state, it is possible to prevent the display panel from being damaged.

Abstract translation: 柔性显示装置包括柔性显示面板，从显示面板延伸的柔性印刷电路板，安装在柔性印刷电路板的至少一个表面上并构造成驱动显示面板的集成电路芯片，以及 保护构件附接到显示面板的后表面。 当柔性印刷电路板弯曲以部分地位于显示面板的后表面上时，保护构件位于显示面板和集成电路芯片之间。 柔性显示装置防止与显示面板堆叠的集成电路芯片使用保护构件直接与显示面板接触。 因此，即使显示装置变形为例如弯曲或滚动状态，也可以防止显示面板被损坏。
