摘要:
A positive active material for a rechargeable lithium battery is a secondary particle formed of an assembly of primary particles of a nickel-based compound. The positive active material has an average particle diameter ranging from 5.5 μm to 7.5 μm and a specific surface area ranging from 0.40 m2/g to 2.0 m2/g. When the positive active material has an average particle diameter ranging from 11 μm to 13 μm, the positive active material has a specific surface area ranging from 0.15 m2/g to 1.0 m2/g. A rechargeable lithium battery includes the positive active material.

Provided is an apparatus and a method for providing a three-dimensional (3D) broadcasting service that may provide a two-dimensional (2D) fixed broadcasting service using a fixed broadcasting signal or a 2D mobile broadcasting service using a mobile broadcasting signal when a transmitter transmits each of a left image and a right image constituting a 3D image using the fixed broadcasting signal or the mobile broadcasting signal, and the receiver receives the fixed broadcasting signal and the mobile broadcasting signal, or may provide a 3D broadcasting service by composing an image received using the fixed broadcasting signal and an image received using the mobile broadcasting signal into a 3D image.
摘要:
The present disclosure relates to a method and an apparatus for capturing an image in a portable terminal. Upon receiving an image for preview and an image for capture simultaneously by a camera module, the controller simultaneously outputs the image for the preview and the image for the capture to a main controller during a simultaneous output mode. The received image for the preview is displayed and stored for a predetermined time period for a subsequent retrieval, so that when a capture key is pressed to capture a target object, the stored image corresponding to a time point at which the capture key is activated is retrieved and stored.

摘要:
A liquid crystal display according to an exemplary embodiment of the present invention includes: a first substrate and an opposing second substrate; a first pixel electrode and a second pixel electrode disposed in a pixel area, on the first substrate, and including a plurality of branch electrodes; and a liquid crystal layer interposed between the first and second electrodes. Branches electrode of the first pixel electrode and the second pixel electrode are interlaced. The first pixel electrode has an extension disposed adjacent to the center of the pixel area, and a minimum distance between the extension and the adjacent branch electrode is different from an average minimum between the adjacent branch electrodes.
