Abstract:
A method and device for receiving a digital multimedia broadcasting (DMB) signal in a wireless terminal where an external antenna is detachable from the wireless terminal, an internal antenna is embedded in the wireless terminal, a switch connects one of the external antenna and the internal antenna to a DMB receiver. The DMB receiver receives a DMB signal through one of the external antenna and the internal antenna. A controller controls the switch to connect the internal antenna and transmit the DMB signal to the DMB receiver when the external antenna is detached from the wireless terminal and controls the switch to connect the external antenna to the DMB receiver and transmit the DMB signal to the DMB receiver, when the external antenna is attached to the wireless terminal.
Abstract:
Disclosed herein is a method of fabricating a light emitting diode. The method comprises preparing a substrate, forming a lower semiconductor layer, an active layer and an upper semiconductor layer on the substrate, forming a photoresist pattern over the upper semiconductor layer such that a sidewall of the photoresist pattern is inclined to an upper surface of the substrate, and sequentially etching the upper semiconductor layer, active layer and lower semiconductor layer using the photoresist pattern as an etching mask. With this structure, since the light emitting diode permits light generated in the active layer to be easily emitted to an outside through the sidewalls of the semiconductor layers, it has improved light emitting efficiency.
Abstract:
A manufacturing method using an additional heat-treatment process for a donor film with improved surface roughness. The improved donor film, used in a laser induced thermal imaging method, is capable of enhancing the lifetime of products and reducing the defect rates thereof. A manufacturing method for a donor film according to the invention, includes: providing a donor film comprising a base film, a light-to-heat conversion layer and an organic film; heating the donor film to provide a heat-treated donor film; and cooling the heat-treated donor film. The surface roughness of a donor film can be improved, and the non-uniform distribution of a laser on a region subjected to the LITI process can be minimized to prevent the over- or under-transfer of an transferred organic film, etc., and the non-uniform adhesion of the transferred organic film with an acceptor substrate.

Abstract:
Provided is an antenna apparatus for a portable terminal including a first antenna pattern, and a second antenna pattern formed to correspond to the first antenna pattern, so that the second antenna provides a capacitive coupling along with the first pattern, thereby configuring a divergent type antenna with the second antenna pattern. The antenna apparatus configured in this manner comprises a pair of meander line antennas, whereby the antenna apparatus can efficiently suppress the generation of noise while being easily housed within the terminal. Furthermore, the antenna apparatus has an advantage of easily enhancing a specific absorption ratio (SAR) induced in a human body, which is an important factor for defining the function and quality of an antenna apparatus.
