Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

Abstract: 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 device includes a housing configured to house the rollable display and configured to roll in and roll out the rollable display along a first direction, and a capacitive sensor including a transmitter and a receiver electrode disposed within the housing and configured to sense the pattern.

Abstract: A light-emitting element ink, a display device, and a method of fabricating the display device are provided. The light-emitting element ink includes a light-emitting element solvent, light-emitting elements dispersed in the light-emitting element solvent, each of the light-emitting elements including a plurality of semiconductor layers and an insulating film that surrounds parts of outer surfaces of the semiconductor layers, and a surfactant dispersed in the light-emitting element solvent, the surfactant including a fluorine-based and/or a silicon-based surfactant.

Abstract: A switching frame includes information on a carrier-to-interference ratio that is included on a first time slot corresponding to a boundary with a previous frame and corresponds to a target coverage area having a first power level, and at least on up/down command information for the carrier-to-interference ratio that is included after the first time slot and has the same power level as the first power level.

Abstract: A method of performing power control in a mobile communication system is disclosed. In the method, power control information is transmitted to a terminal by using a terminal power control threshold of the terminal being changed in due consideration of a communication circumstance in case of that a high-speed data transmission terminal is scheduled during receiving low-speed and voice data from the terminal.
