An image sound device is provided. The image sound device includes a housing including an upper end portion that includes an opening and a storage space inside the housing; a display including a display area for displaying video contents; a lifter; a speaker; a motor controller configured to control the lifter wherein the display is positioned at at least three height positions; and a controller configured to control the display to display an image on the display area and output sound.

Image sound device having display portion that can appear/disappear

A three-dimensional semiconductor memory device is provided. The memory device includes a substrate with a cell array region and a connection region adjacent to the cell array region, the connection region including a first pad region and a second pad region; an electrode structure including electrodes stacked on the substrate, the electrode structure including an upper portion forming an upper staircase structure; a first dummy structure laterally spaced apart from the upper portion of the electrode structure and provided on the first pad region; and a second dummy structure laterally spaced apart from the upper portion of the electrode structure and provided on the second pad region. Each of the first dummy structure and the second dummy structure includes a dummy staircase structure, and the first dummy structure is located at higher level than the second dummy structure.

Three-dimensional semiconductor memory device and method of manufacturing the same

An electronic device that is interlocked with a display device and a method for controlling the electronic device are provided. The method includes acquiring an image by photographing an area in which the display device is installed, identifying a display area in which the display device is disposed and a background area of the display device by analyzing the acquired image, acquiring information that relates to a background image of a position at which the display device is installed based on the identified background area, and transmitting the acquired background image information to the display device.

Electronic device and method for controlling the same

The present invention relates to an image sound device having a display portion that can appear/disappear, the device comprising: a housing, the upper end of which is open, and which has a space provided therein; a display portion installed inside the housing to be able to output images; an elevating unit installed inside the housing and below the display portion such that the display portion can be made to protrude through the upper end of the housing; and a motor control portion for controlling the elevating unit such that the display portion can be positioned at two or more heights.

An electronic apparatus includes a display and a processor for controlling the display. In response to the electronic apparatus operating in a first operating mode, the processor displays a content screen including a background image layer with a rear background image of the electronic apparatus and an object layer with a graphic object in the display. In response to receiving a convert command to convert to a second operating mode, the processor decreases a resolution of the content screen displayed in the display and adds a content layer including a content image enlarged gradually from a region of the content screen to the an entirety of the content screen.
