A computer-implemented method includes: identifying, by a computing device, private portions and non-private portions of content displayed on a user device; generating, by the computing device, instructions to modify the display of the content on the user device to mask the private portions of the content, group the private portions of the content together, and group and the non-private portions of the content together; and outputting, by the computing device, the instructions to cause the user device to modify the display of the content on the user device such that the masked private portions of the content are grouped together and the non-private portions of the content are grouped together, wherein the non-private portions are exposed and visible.

A scan driving circuit of a display device includes a first output terminal electrically connected to a first scan line, a second output terminal electrically connected to a second scan line, a first masking circuit electrically connecting the first output terminal and the second output terminal and outputting, as a first scan signal, a second scan signal to the first output terminal, a driving circuit outputting the second scan signal to the second output terminal in response to clock signals and a carry signal, and a second masking circuit masking the second scan signal to a predetermined level in response to the second masking signal, wherein the first masking circuit electrically disconnects the first output terminal from the second output terminal in response to a first masking signal.

Embodiments relate to a display device including two or more sections of pixels in a display area powered by supply voltages in power rails. The display device also includes two or more power detection circuits connected to two or more locations along the power rails to detect local voltages at the locations. Depending on an image being display during a frame, the two or more sections of pixels may cause changes in local voltages at the two or more locations. The detected local voltages are provided to two or more voltage regulators, and the two or more voltage regulators update supply voltages provided to the power rails to compensate for the changes in the local voltages.

An operating method of an electronic device is provided. The method includes measuring an external temperature of the electronic device by using at least one sensor. The method may calculate, from an entire region of a flexible display, a fixed region that is visually exposed to an outside regardless of a screen size of the electronic device, and a variable region that is visually exposed at least in part to the outside in a screen expansion or screen size change state of the electronic device. The method may compare the external temperature with a preset first threshold temperature, thereby determining heating of the variable region in response to the external temperature being less than the first threshold temperature. The method may heat the variable region by controlling at least one of a luminance or a driving frequency of the variable region.

A local-dimming display generally includes a light source configured to generate a backlight, a first display aligned with the light source and having multiple first pixels, wherein each first pixel is configured to selectively pass and block the backlight, and a second display aligned with the first display and having multiple second pixels. A particular pixel is controlled to pass the backlight. The particular pixel corresponds with an aligned pixel and multiple parallax pixels of the first pixels controlled at a first transmit level, and multiple neighboring pixels of the first pixels controlled at one or more second transmit levels. The one or more second transmit levels are less than or equal to the first transmit level. The first pixels cooperating at the first transmit level and the second transmit levels selectively presents the backlight to the second display with a declining intensity pattern in the neighboring pixels.

An embodiment of a display apparatus includes a display panel, a driving controller, and a data driver. In operation the driving controller determines a gain reducing area based on an edge load of input image data corresponding to an edge area of the display panel and compensates a grayscale value of the input image data corresponding to the gain reducing area to generate a data signal. The data driver converts the data signal to a data voltage and outputs the data voltage to the display panel.
