Disclosed herein is a method for constructing a joint between thin flexible sheets of electromagnetic shielding material. The method includes adhering first sides of multiple first sheets of shielding material to a wall and adhering first sides of multiple second sheets of shielding material to second sides of the multiple first sheets of shielding material. A conductive adhesive or a conductive double-sided adhesive tape may be applied to the first side of each of the first sheets of shielding material and the second sheets of shielding material, the first sheets of shielding material may be arranged to abut each other along at least one first seam, and the second sheets of shielding material may be arranged to abut each other along at least one second seam.

A light emitting diode (LED) package includes: a main body mounted on a substrate; a light emitting diode that is mounted in the main body and emits light; and a lead frame exposed to allow the main body to be selectively top-mounted or side-mounted. A backlight unit includes: a light guide plate configured to allow a light source to proceed to a liquid crystal panel; a light emitting diode (LED) mounted in a main body mounted on a substrate and generating a light source; and an LED package having a lead frame exposed to allow the main body to be selectively top-mounted or side-mounted, and being mounted on the light guide plate.

LED package and a backlight unit comprising said LED package

Provided are a method and apparatus for entropy-encoding/entropy-decoding video data. The method of entropy-encoding video data includes binarizing coefficients of the frequency domain, which are generated by transforming a residual block of a current block into the frequency domain, using different binarization methods and performing binary arithmetic coding on the binarized coefficients. In this way, the coefficients are binarized adaptively according to whether the frequencies of the coefficients are high or low, thereby improving the compression efficiency of the video data.
