Abstract:
A power amplifier includes first and second amplification stages. The first amplification stage is configured to amplify a radio frequency (RF) input signal. The second amplification stage includes at least one transistor configured to amplify an output of the first amplification stage, the second amplification stage being configured to have a capacitance between a gate of the at least one transistor and a first power supply voltage. The capacitance automatically varies with amplitude of the output of the first amplification stage.

Abstract:
A flat panel display capable of preventing a chipping phenomenon of a pixel definition layer, and a method for making the same are disclosed. The flat panel display includes a thin film transistor formed on a substrate; a planarization layer formed on the thin film transistor; a first electrode layer formed on the planarization layer and electrically connected with the thin film transistor through the via hole formed in the planarization layer; a pixel definition layer formed on the planarization layer and in which an opening for at least partially exposing the first electrode layer is formed; an adhesive reinforcement layer formed at least between the planarization layer and the pixel definition layer on the top of the planarization layer; an emitting layer formed on the first electrode layer; and a second electrode layer formed on the emitting layer and the pixel definition layer. The flat panel display has an improved adhesive property between a pixel definition layer and an planarization layer, which prevents a chipping phenomenon of the pixel definition layer.
Abstract:
Disclosed herein is a refrigerator which comprises an icemaker. In the refrigerator, a printed circuit board for ice-making positioned in the icemaker shares some components with a main printed circuit board, or the main printed circuit board receives some components used for the icemaker in place of the printed circuit board for ice-making, thereby providing various effects. The refrigerator comprises an icemaker to perform automatic ice-making operation of freezing water supplied from an outside to produce ice cubes, a first printed circuit board to control a freezing operation for a freezing compartment of the refrigerator, and a power supply unit shared by the icemaker and the first printed circuit board.
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:
An illuminated exterior decorative device for vehicles includes a decorative part and an illuminating part. The illuminating part illuminates the decorative part from behind and includes a light source and a light diffusion portion. The light source of the illuminating part is embedded in the light diffusion portion. The light diffusion portion of the illuminating part is optically transmissive, preferably transparent. The light source is disposed along the edge of the decorative part. The light source includes a plurality of light emitting device (LED). The illuminating part has substantially the same pattern as the decorative part. The decorative part may be provided as metal coating on the illuminating part.
Abstract:
The present invention relates to a washing machine which can selectively performs a water washing and an oil washing by using one washing tub, wherein the washing machine has a self-diagnostic function and a communication function. In accordance with the present invention, the water washing and the oil washing can be performed with respect to one washing tub by completely removing alien material and the oil remaining on the washing tub and deterioration of the laundry can be avoided, while providing economic benefits by using the oil reclaimed by a reclamation process. Further, since the present invention has a self-diagnostic function and remote maintenance function for assisting the user, it has an advantage in that the user can easily finish the maintenance in a shorter time.
Abstract:
Embodiments of methods and apparatus for recording at least two broadcast programs that are consecutive in time can consecutively record the plurality of programs (e.g., consecutively) on a recording medium without a process of creating and recording navigation information between programs. Navigation information for the recorded section can be created and recorded on the recording medium after the consecutive recording of the plurality of programs is completed. Such navigation information can consider the consecutive broadcast programs as a single entity or a plurality of individual entities (e.g., for play back).
Abstract:
An apparatus and method thereof determines a title of a recorded program. After a desired video content that is transmitted through a channel has been recorded upon user's request of timer recording, it is checked if more than one program is scheduled for broadcast on that channel during the preset timer recording interval based on broadcast program time information obtained from the channel. If it is determined that more than one programs is scheduled, the title of the recorded desired video content is determined on the basis of time length, data size, and/or minimum ratio.
