Abstract:
A display panel includes a first light source, a second light source having a color different from a color of the first light source, a light guide plate converting a point light source generated by the first light source and the second light source into a surface light source, a diffuser plate positioned on an upper portion of the light guide plate and diffusing the surface light source emitted by the light guide plate, and a frame supporting the light guide plate and the diffuser plate and including a protrusion protruded between the diffuser plate and the light guide plate.
Abstract:
A semiconductor memory device has a plurality of gates vertically stacked on a top surface of a substrate, a vertical channel filling a vertical hole that extends vertically through the plurality of gates, and a memory layer in the vertical hole and surrounding the vertical channel. The vertical channel includes a bracket-shaped lower portion filling part of a recess in the top of the substrate and an upper portion extending vertically along the vertical hole and connected to the lower channel. At least one end of an interface between the lower and upper portions of the vertical channel is disposed at a level not than that of the top surface of the substrate.
Abstract:
Disclosed are three-dimensional semiconductor memory devices and methods of fabricating the same. The method includes sequentially forming a sacrificial pattern and a source conductive layer on a substrate, forming a mold structure including a plurality of insulating layers and a plurality of sacrificial layers on the source conductive layer; forming a plurality of vertical structures that penetrate the mold structure, forming a trench that penetrates the mold structure, forming a sacrificial spacer on a sidewall of the trench, removing the sacrificial pattern to form a horizontal recess region; removing the sacrificial spacer, and forming a source conductive pattern that fills the horizontal recess region.
Abstract:
Provided is an image encoding method including generating a first picture reconstructed by using a residual picture and a predicted picture; generating a second picture by applying a first artifact reduction filter to the first picture; determining a picture having a smaller bit-rate distortion cost from among the first and second pictures by comparing a first bit-rate distortion cost of the first picture with a second bit-rate distortion cost of the second picture; generating a third picture by applying an in-loop filter to the determined picture; generating a fourth picture by applying a second artifact reduction filter to the third picture; determining a picture having smaller distortion from among the third and fourth pictures by comparing first distortion of the third picture with second distortion of the fourth picture; and generating, via a processor, a bitstream including information about whether the second artifact reduction filter is applied.
Abstract:
A wafer polishing pad includes a first pad having a first surface configured to receive a platen. A protrusion is disposed on the first surface of the first pad. The protrusion is disposed on an edge region of the first pad in a plan view such that a side surface of the protrusion makes contact with a side surface of the platen when the first pad is disposed on the platen.
Abstract:
A system and method is provided that authenticates a user using hybrid biometrics information, such as a user's image information, a user's voice information, etc. The user authentication method includes: acquiring a number of biometrics information; generating a number of authentication information corresponding to the acquired biometrics information; and performing an integral user authentication based on the by generated authentication information.
Abstract:
An operation method capable of adaptively operating at least one of a Speech To Text (STT) service and a Text To Speech (TTS) service according to setting or user operation and a system thereof are provided. The method includes requesting a specific type of a communication service connection to a reception side terminal by a transmission side terminal, and performing an operation of at least one of a speech to text service providing speech recognition based text and a text to speech service converting the text into speech data between the reception side terminal and the transmission side terminal, and includes one of recognizing speech data provided from the transmission side terminal and converting the speech data into a text based on a first speech process supporting device connected to the transmission side terminal.
Abstract:
A method of performing a voice command function in an electronic device includes detecting voice of a user, acquiring one or more pieces of attribute information from the voice, and authenticating the user by comparing the attribute information with pre-stored authentic attribe information, using a recognition model. An electronic device includes a voice input module configured to detect a voice of a user, a first processor configured to acquire one or more pieces of attribute information from the voice and authenticate the user by comparing the attribute information with a recognition model, and a second processor configured to when the attribute information matches the recognition mode, activate the voice command function, receive a voice command of the user, and execute an application corresponding to the voice command. Other embodiments are also disclosed.
