A printed circuit board ('PCB') includes a first pattern structure, a second pattern structure, a third pattern structure, and a fourth pattern structure. The first pattern structure includes a first ground pattern. The second pattern structure includes a first line pattern overlapping the first ground pattern and a second ground pattern electrically insulated from the first line pattern. The third pattern structure includes a third ground pattern overlapping the first line pattern and a second line pattern overlapping the second ground pattern. The fourth pattern structure includes a fourth ground pattern overlapping the second line pattern. Therefore, the PCB may decrease noise.

A method of displaying a three-dimensional ('3D') image includes displaying a left-eye image and a right-eye image on a display panel, the display panel including a first sub pixel, a second sub pixel, a third sub pixel and a fourth sub pixel sequentially arranged in a row direction and driving an active barrier panel to form an opening part configured to transmit light and a barrier configured to block light, the active barrier panel including a first barrier electrode, a second barrier electrode, a third barrier electrode and a fourth barrier electrode respectively corresponding to the first, second, third and fourth sub pixels.

Method of displaying a three dimensional stereoscopic image and a display apparatus for performing the method

A memory controller includes an digitally programmable delay unit having a selectable delay time receiving a read-enable signal and outputting a delayed read-enable signal. The delay time is selected in response to an externally applied delay-control signal. A sampling unit in the memory controller outputs data received from a separate memory, in synchronization with the delayed enable signal. The delay time may be a multiple of the period of a clock signal.

Memory controller

A method and apparatus for detecting a free page of a memory device, and a method and apparatus for decoding an error correction code by using the method and apparatus for detecting a free page are provided. Free page data read from the memory is converted into a converted codeword for inclusion as an element of an error correction code field. The converted codeword is compared to an initially set target codeword to detect an amount of non-identical bits. A page read from the memory is determined to be a free page when the amount of non-identical bits is equal to or less than an initially set threshold value.

Method and apparatus for detecting free page and a method and apparatus for decoding error correction code using the method and apparatus for detecting free page

A display device includes a display panel, and a chassis supporting the display panel, and including a conductive material. The display device includes a circuit board including a signal wiring connected to the display panel to apply a driving signal to the display panel, and a grounding wiring for grounding. The display device includes a connector connected with a signal cable that applies an external signal and is connected to the signal wiring and the grounding wiring of the circuit board. The display device includes an exposed grounding unit exposing part of the grounding wiring on the circuit board, wherein the exposed grounding unit is disposed adjacent to the connector. The display device includes a conductive member which connects the exposed grounding unit with the chassis.

Display device, manufacturing method of the display device, and portable computer having the display device

In a display apparatus and a method of assembling the display apparatus according to one or more embodiments, a printed circuit board is electrically connected to a lower end of a display panel and disposed in a rear surface of a container. A flexible printed circuit board is contained in the container, and light sources are mounted on the flexible printed circuit board. A connection film electrically connecting the printed circuit board and the flexible printed circuit board is disposed on a bottom portion of the container, and one end of the connection film passes through a fixing hole formed through the bottom portion. The one end of the connection film is electrically connected to the printed circuit board disposed in the rear surface. Thus, movement of the connection film may be limited by an inner wall defining the fixing hole.
