Methods, apparatuses and systems provide for technology to identify a communication that is to be presented to a user. The technology controls a first plurality of actuators to press a first portion of a light emitting element (LEE) layer against a deformable layer to deform the deformable layer into a shape that represents the communication to be presented to the user, and controls the LEE layer to emit light from the first portion of the LEE layer that is pressed against the deformable layer to illuminate the shape of the deformable layer.

In an example, a display device includes a rollable display including a display side and an opposite non-display side. The rollable display includes a conductive material with a pattern disposed on the non-display side.

The included angles between the orthogonal directions and the corresponding inclined directions are acute angles. A ratio of a difference between the first normal brightness and the second normal brightness to the first normal brightness is less than a ratio of a difference between the first oblique brightness and the second oblique brightness to the first oblique brightness is defined as a second ratio.

A display device includes a main body configured to have a display module to which a user interface is output, a bending module located at a center of a back surface of the main body, and a controller. The controller controls the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module. Then, the controller changes at least one of a size and a position of a display region to which the user interface is output, according to whether a mode is the flat mode, the first bending mode, or the second bending mode.

The electronic apparatus comprises: a display device; an image acquisition device, which is configured to acquire a surrounding image of the display device; and a processor, which is configured to determine a background image of the display device according to the surrounding image, acquire a target range, and a target object in the background image, determine a target image according to the background image, the target range and the target object, and control the display device to display the target image, wherein the target image does not include the target object.

Provided herein may be a display device and a method of controlling a plurality of display devices. The method may include displaying, on a first display device, a first image including a first partial image, a second partial image, and a third partial image, transmitting, by the first display device, a second image including a fourth partial image corresponding to the first partial image, a fifth partial image corresponding to the second partial image, and a sixth partial mage corresponding to the third partial image to a second display device, displaying the second image on the second display device, receiving, by the first display device, a first touch input for a first input interface included in the third partial image, and receiving, by the first display device, a second touch input for at least one of the fourth, fifth partial image, and sixth partial images.

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.
