摘要:
An organometallic complex for an organic light-emitting layer and an organic light-emitting diode are provided. A naphthalene derivative as a ligand is introduced to the organometallic complex. The organic light-emitting diode uses the organometallic complex as a phosphorescent host material. The organic light-emitting diode exhibits high current efficiency, high power efficiency and long lifetime when compared to conventional devices using BAlq.

Disclosed is a plasma etching chamber for completely dry-cleaning a film material and particles deposited at the periphery of a wafer through plasma etching while generating plasma at the top to the bottom sides of the periphery of the wafer. A pair of top and bottom anodes facing each other is placed around the periphery of the wafer under the application of radio frequency through a cathode. Alternatively, a top cathode and a bottom anode are placed around the periphery of the wafer while facing each other and a view-ring shields the area of the cathode, the anode and the wafer from the outside. A plasma etching system includes a plurality of the above-structured etching chambers. A handler takes wafers from a plurality of cassette stands or load ports, and posture-corrects the orientation frat locations of the wafers by a wafer alignment unit. The wafers are charged into the plasma etching chambers directly or via load lock chambers. The handler takes the etched wafers from the chambers, and returns the wafers to the cassettes or the load ports directly or via the load lock chambers.

Disclosed is a method for outputting a digital broadcast with a digital broadcast receiver terminal. The method includes storing first digital broadcast data as second digital broadcast data by the digital broadcast receiver terminal from a moment when an incoming call is connected while the first digital broadcast data is outputted and outputting the first and second digital broadcast data simultaneously to a digital broadcast output screen when connection of the incoming call is terminated. According to the method, a portion of a digital broadcast, which a user fails to watch due to an incoming call, is stored and, after the call, outputted on a separate screen.

Disclosed is a method for providing an interactive digital broadcasting service in a mobile communication terminal for receiving digital broadcasting. Digital broadcasting signals including URL information of the digital broadcasting are received and outputted, the URL information from the received digital broadcasting signals is detected, a website of the digital broadcasting is accessed using the detected URL information when a broadcast information request for the digital broadcasting is received from a user, and broadcasting information provided from the website is displayed in a portion of a digital broadcasting output screen. Thus, while watching the digital broadcasting, users can access the Internet, retrieve information relating to broadcasting contents and state their opinion about broadcast programs.
摘要:
The present invention relates to an infrared rays touch screen apparatus using an array of infrared elements in two opposite sides comprising: a plurality of infrared rays transmitting elements arranged sequentially in a first direction; a plurality of infrared rays receiving elements arranged sequentially in the first direction and in the opposite side of the plurality of infrared rays transmitting elements to receive infrared rays transmitted from the plurality of infrared rays transmitting elements; and a touch control unit which is operated in a first scan control mode which controls the plurality of infrared rays receiving elements and the plurality of infrared rays transmitting elements such that each infrared rays receiving element receives infrared rays from the infrared rays transmitting elements arranged in the opposite side and which is operated in a second scan control mode which controls such that each infrared rays receiving element receives infrared rays from the infrared rays transmitting elements arranged diagonally to the infrared rays receiving element; wherein the touch control unit detects the first touch coordinates of the first direction by the operation in the first scan control mode, and detects the second touch coordinates of the second direction perpendicular to the first direction on the basis of the first touch coordinates of the first direction and a preliminary coordinates of the first direction detected by the operation in the second scan control mode. Accordingly, the single-touch and multi-touch are able to be sensed by a plurality of infrared rays transmitting elements and infrared rays receiving elements arranged which are arranged in the two opposite sides on the screen, thereby the manufacturing cost can be reduced significantly.
