Provided are holographic display systems and methods for generating a hologram by compensating for aberrations of a holographic display device. The holographic display system may include a holographic display device and a hologram generating device. The hologram generating device may generate a hologram by propagating hologram segments, using kernels generated by modeling each aberration corresponding to each of hologram plane segments to compensate for aberrations.

Holographic display system and method for generating hologram by compensating for aberration of holographic display device

Provided is a method of generating a hologram, the method including generating a kernel and a neural network configured to model an aberration of a holographic display device, obtaining second image data output from the neural network to which first image data obtained by propagating a first hologram based on the kernel is input, updating the kernel and the neural network based on comparing the second image data and predetermined image data, and generating a second hologram based on the kernel and the neural network.

3D semiconductor memory devices may include a horizontal structure that may be on an upper surface of a substrate and may include first and second horizontal patterns sequentially stacked on the upper surface of the substrate, a stack structure including electrodes stacked on the horizontal structure, a vertical pattern extending through the electrodes and connected to the first horizontal pattern, and a separation structure intersecting the stack structure and the horizontal structure and protruding into the upper surface of the substrate. A lowermost electrode may have first inner sidewalls facing each other with the separation structure interposed therebetween. The second horizontal pattern may have second inner sidewalls facing each other with the separation structure interposed therebetween. A maximum distance between the first inner sidewalls in the first direction may be less than a maximum distance between the second inner sidewalls in the first direction.

Three-dimensional semiconductor memory devices

A mobile terminal and a method of controlling the mobile terminal are disclosed. In the mobile terminal, at least one second application executable in a second operating system different from a first operating system can be searched and provided among at least one first application executable in the first operating system. Accordingly, it is possible to provide a user interface for efficiently managing applications so as to be appropriate for various operating systems.
