Abstract: An embodiment fuel cell including a high temperature polymer electrolyte membrane includes an electrolyte membrane including a phosphoric acid-doped polymer of intrinsic microporosity, a cathode disposed on a first surface of the electrolyte membrane, and an anode disposed on a second surface of the electrolyte membrane, the second surface opposite the first surface.

Abstract: An electroluminescent display device includes an electroluminescent display device includes a substrate; a first pixel row on the substrate including a first plurality of pixels arranged along a first direction; a second pixel row on the substrate including a second plurality of pixels arranged along the first direction, the second pixel row being spaced apart from the first pixel row in a second direction; a first groove between the first and second pixel rows; and a light emitting diode in each pixel of the first and second pixel rows, wherein the first groove includes a first portion at one end of the first pixel row, a second portion at the other end of the first pixel row and a third portion between the first and second portions, and wherein third portion is smaller than the first portion and greater than the second portion.

Abstract: A display apparatus having a digital record function and a method thereof. The display apparatus includes a broadcasting program memory in which a broadcasting program is stored; an up/down reproduction selecting part for selecting reproduction of the broadcasting program stored in the broadcasting program memory; and a controller for controlling the signal processing part to process the broadcasting program corresponding to selection of the up/down reproduction selecting part and display the processed broadcasting program on the display according to a stored temporal order of the stored broadcasting programs.

Abstract: A display apparatus and a channel navigation method thereof are provided. The channel navigation method of a display apparatus using picture-in-picture (PIP), included: processing video signals of a currently tuned channel to be displayed in a main picture; generating a channel list including a sub picture based on the video signal corresponding to a predetermined channel when a channel navigation function is selected; and displaying the generated channel list on an area of the main picture. With this method, a channel list including a PIP picture is displayed on an area of a main picture, so that a user can select a desired channel through broadcasting information and pictures about other channels while viewing the main picture.

Abstract: A method and broadcast receiving apparatus are provided for offering seeing-information. The method includes a determination as to whether a current seeing point change manipulation to change a current seeing point of time into a point of time prior to a current broadcast point of time is input. If a determination is made that the current seeing point change manipulation is input, prior point notice information is displayed as texts on a broadcast to be replayed to give notice that the current seeing point of time is prior to the current broadcast point of time.

Abstract: Provided are a method for offering a selection point number to a recording image and an image reproducing apparatus thereof. The method includes: respectively assigning selection point numbers to the selection points of the recorded image; and displaying information as to the selection points and the selection point numbers assigned to the selection points on an image to be reproduced.
