| 20090221209 | METHOD OF MANUFACTURING A LIGHT-EMITTING ELEMENT AND METHOD OF MANUFACTURING A DISPLAY SUBSTRATE USING THE SAME - In accordance with one or more embodiments of the present disclosure, a method of manufacturing a light-emitting element includes forming an anode on a substrate, forming a first transport layer including one or more first polar compounds on the anode, forming a first non-polar solvent layer on the first transport layer, forming a first polar solution layer including one or more light-emitting compounds on the first non-polar solution layer, drying a polar solvent of the first polar solution layer and the first non-polar solvent layer so that a light-emitting layer including the one or more light-emitting compounds is formed on the first transport layer and forming a cathode on the light-emitting layer. The cathode is disposed opposite to the anode. As such, damage to the first transport layer may be reduced when forming the light-emitting layer, which may improve the reliability and productivity of a manufacturing process. | 09-03-2009 |
| 20110110176 | ADDRESS CONTROL CIRCUIT AND SEMICONDUCTOR MEMORY DEVICE - An address control circuit is presented for use in reducing a skew in a write operation mode. The address control circuit includes a read column address control circuit and a write column address control circuit. The read column address control circuit is configured to generate a read column address from an address during a first burst period for a read operation mode. The write column address control circuit is configured to generate a write column address from the address during a second burst period for a write operation mode. | 05-12-2011 |

| 20080229364 | System and Method for the Construction of Electronic Program Guide Through Cooperative Transmission of Electronic Program Guide Data - The present invention relates to a system and a method for the construction of EPG service through cooperative transmission of electronic program guide data. The system of the present invention comprises an EPG transmission server transmitting, through a forward path mediated by a broadcasting network, a part of total EPG data to be transmitted to a settop box and data into which request commands for remaining EPG data not transmitted via the broadcasting network are embedded; an EPG head end server transmitting the remaining EPG data in response to user's request through a return path mediated by a communication network; and a settop box equipped with an EPG application which processes the EPG data received from the EPG transmission server and the EPG head end server. The EPG data transmitted via the broadcasting network includes both a service description table and an event information table. The system and the method for the construction of EPG service in accordance with the present invention require a significantly reduced broadcasting bandwidth for the EPG data transmission, compared with the conventional method or system. EPG service construction can be achieved using the broadcasting bandwidth of 2 M or smaller. Also, the system is applicable to various EPG applications without sacrificing user's satisfaction at all. | 09-18-2008 |
| 20100031300 | OPERATING METHOD OF CONTENTS ON DEMAND SYSTEM - A method of effectively operating a Content-On-Demand (COD) system is disclosed. Requests for content are received from COD clients. If the requested content exists in a COD server and the content is content for one-to-one transmission, a session is set up between the COD server and one of the COD clients by providing access information for one-to-one transmission. Thereafter, the requested content is transmitted to the corresponding COD client in a one-to-one transmission manner, and then the session is terminated when the transmission is completed. If the requested content is content for one-to-N transmission, sessions are set up between the COD server and the respective COD clients by providing access information for one-to-N transmission. Thereafter, the requested content is transmitted to the corresponding COD clients in a one-to-N transmission manner when a one-to-N transmission requirement is met, and then the sessions are terminated when the transmission is completed. | 02-04-2010 |
| 20100180317 | Method and device for controlling the point of time of the operation of an application in digital data broadcasting - A device and method for controlling the operating mode of an application included in service data which is transmitted together with a broadcast program, are disclosed. A digital broadcast system includes a digital broadcasting device which transmits service data together with a broadcast program, wherein the service data includes an application which allows a digital broadcasting receiver to perform a particular operation and information associated with the operating mode of the application. The digital broadcast system also includes a digital broadcasting receiver which receives the service data and executes the application when the operating mode of the application is an initial operating mode, and otherwise, waits until there is a service request by a viewer, and then executes the application. The digital broadcast system for broadcasting additional service data together with broadcast programs can arbitrarily select the point of time at which an application provided to a digital broadcast receiver is executed, during the manufacture of contents, so that various types of interactive services can be provided. | 07-15-2010 |
