摘要:
A display apparatus includes a first substrate and a second substrate opposite to the first substrate. The first substrate includes a plurality of color pixels and a white pixel that outputs a second white light having a same gray scale as a first white light formed by mixing light outputted from the plurality of color pixel. The white pixel is activated by a second current that is lower than a first current that activates the color pixels.

Provided are a method of fabricating a light-emitting apparatus with improved light extraction efficiency and a light-emitting apparatus fabricated using the method. The method includes: preparing a monocrystalline substrate; forming an intermediate structure on the substrate, the intermediate structure comprising a light-emitting structure which comprises a first conductive pattern of a first conductivity type, a light-emitting pattern, and a second conductive pattern of a second conductivity type stacked sequentially, a first electrode which is electrically connected to the first conductive pattern, and a second electrode which is electrically connected to the second conductive pattern; forming a polycrystalline region, which extends in a horizontal direction, by irradiating a laser beam to the substrate in the horizontal direction such that the laser beam is focused on a beam-focusing point within the substrate; and cutting the substrate in the horizontal direction along the polycrystalline region.

A nonvolatile memory device comprises a memory cell array, a row selection circuit and a voltage generator. The memory cell array comprises a first dummy memory cell, a second dummy memory cell, and a NAND string comprising a plurality of memory cells coupled in series between a string selection transistor and a ground selection transistor through the first dummy memory cell and the second dummy memory cell. During a read-out operation mode, a dummy read-out voltage is applied to a first dummy wordline coupled to the first dummy memory cell, and to a second dummy wordline coupled to the second dummy memory cell. The dummy read-out voltage has a lower magnitude than a read-out voltage applied to an unselected memory cell during the read-out operation mode.

The flash memory device of the present invention is configured to program a plurality of bits per unit cell, wherein a program condition of a selected bit is set according to whether a program for the most previous bit to the selected bit for programming is skipped or not skipped. As a result, an accurate programming and reading operation is possible even in case a program for a middle bit is skipped.
摘要:
A method for programming a flash memory device including a plurality of memory cells, each storing multi-bit data, includes reading data from selected memory cells. An error of the read data is detected and corrected. Input program data is programmed into the selected memory cells based upon the error-corrected read data.

A light emitting device having a high degree of light extraction efficiency includes a substrate, and a light emitting structure disposed on one surface of the substrate, the substrate having an internal reformed region where the index of refraction differs from the remainder the substrate. The ratio of the depth of the reformed region (distance between the other surface of the substrate and the reformed region) to the thickness of the substrate is in a range of between 1/8 and 9/11.
摘要:
A secure transmission of a device management message via a broadcast (BCAST) channel, by which a BCAST server can securely transmit a device management message including an authentication value to a plurality of terminals via a one way BCAST channel, and accordingly the terminals is not required to use a separate channel for authenticating the device management message received from the BCAST server.
摘要:
A digital Rights Management (DRM), and particularly an apparatus and method of authentication between DRM agents for moving Rights Object (RO) is provided, whereby RO and contents can be moved between DRM agents after a simple authentication therebetween using specific authentication information received from a Rights Issuer (RI), in case where the RO is moved in a user domain or among a plurality of DRM agents.
摘要:
A flash memory system includes a multi-bit flash memory device having a memory cell array including memory cells arranged in rows and columns; a read circuit configured to read data from the memory cell array; and control logic configured to control the read circuit so as to successively read data from a selected memory cell and adjacent memory cells to the selected memory cell in response to a request for a read operation with respect to MSB data stored in the selected memory cell. A compare circuit is configured to compare data read from the adjacent memory cells to the selected memory cell provided from the multi-bit flash memory device and to correct data read from the selected memory cells based upon the comparison result.
