Abstract: A touch display device comprises a controller to generate a touch sync signal for controlling timing of a touch sensing period and a display period. A touch panel has a plurality of touch electrodes in a display area of the touch display device. The touch panel generates touch sensing signals indicating whether or not a touch occurs during the touch sensing period. A gate driver supplies gate pulses to gate lines of the touch panel during the display period and supplies a gate line auxiliary drive signal from the first transfer line onto the gate lines during the touch sensing period that mimics the touch drive signal. One or more auxiliary lines supply a supplemental auxiliary drive signal during the touch sensing period that mimics the touch drive signal.

Abstract: A system and method for buying goods and billing agency using short message service are disclosed. If a purchaser transmits goods information to a mobile communication service system using short message service of a mobile phone, the mobile communication service system generates a certification code corresponding to the goods information and transmits it to a shopping mall server and the mobile phone. Then, the shopping mall server and the mobile phone exchange messages and run mutual authentication. Thereby, system construction expense for selling goods and service is decreased, purchasing procedure is simple, and the safe purchase can be done by mutual authentication using the certification code.

Abstract: A method and device for providing a mobile subscriber with access to non-subscriber mobile services via the use of a virtual mobile phone number is disclosed. In one embodiment, the method comprises i) receiving a mobile service request from a user terminal, ii) determining whether or not the user is a home subscriber, iii) requesting that a virtual mobile phone number be provided if the user is a non-subscriber, iv) receiving the virtual mobile phone number from the user terminal, v) providing a corresponding mobile service if the received virtual phone number is verified, and vi) charging for use of the mobile service based on the virtual mobile phone number.

Abstract: A system and method for buying goods using a number based domain and the mobile Internet are disclosed. In one embodiment, the system extracts a shopping mall code from number domain information received from a user terminal. Then, if the extracted shopping mall code exists in a pre-stored shopping mall list, the system connects the user terminal to a shopping mall server via a network, by retrieving a character domain corresponding to the shopping mall code and transmitting purchasing request information to the shopping mall server. Thereby, the connection process of a shopping mall site and the selection process of purchasing goods can be simplified without adding a new system and creating mobile content.
