Abstract: A technique for removing vertical stripe artifacts generated in a Liquid Crystal Display (LCD) panel, more particularly a technique for compensating for and removing an inter-channel offset voltage of a column driver, which causes the vertical stripe artifacts, is disclosed. An offset voltage generated in each channel for driving each pixel of the LCD panel is detected for a whole signal path and offset voltages detected for all channels are compared and extracted according to a given timing sequence by a common signal comparator, thereby preventing the offset of the detection comparator and reducing a chip size of the column driver in contrary to the prior art. Moreover, an inter-channel offset voltage is detected in a digital circuit mode, thereby compensating for process variations in a semiconductor chip manufacturing process in circuit terms.

Abstract: Inbound Roamer Multimedia Messaging Systems (“IRMMS”) are described that transfer Welcome Multimedia Messages (“MM”) (“WMM”) or Welcome Roaming Content (“WRC”) to devices of inbound roamers. The IRMMS transfers MMs to inbound roamers without involving components of the corresponding home network (HPMN). The MMs include text messages, music clips, voice clips, video clips, photographs, and drawings, but are not so limited. Use of the IRMMS eliminates payment by a VPMN with which a subscriber is roaming to the subscriber's HPMN because components of the HPMN are not included in the transfer of the MMs. Thus, charges typically incurred by the VPMN for transmission of free WMM/WRC sent to the inbound roamer via the HPMN are avoided.
