Abstract: Disclosed is a source driver including a sensing circuit capable of sensing whether a short occurred between a data output line and a power line. The source driver may include: an output circuit configured to output a preset voltage to a display panel in a checking mode; and a sensing circuit configured to sense whether data output lines connecting the output circuit and the display panel are shorted, using the preset voltage, and output a sensing result signal.

Abstract: The present invention relates to a circuit board for COF (Chip on Film) package, which is capable of preventing an influence of coupling noise on a core block of an integrated circuit. The circuit board may include: a base film defined a core block region overlapping a predetermined location of a core block within an integrated circuit and having the same area as or larger area than the core block; first routing patterns formed on the base film; and a first block pattern covering the core block region. The first routing patterns may be formed outside the first block pattern at the same layer as the first block pattern.

Abstract: Disclosed are a display device, and a source driver and a packet recognition method thereof. In the display device, when check information of a control data packet of transmitted transmission data is normal, a control data packet of to be restored is updated with a control data packet of a current cycle, and when the check information is abnormal, the control data packet to be restored is maintained, so that it is possible to normally drive a source signal even through there is an error or a change in the control data packet.

Abstract: A flexible circuit board for a display, having a chip-on-film structure, is disclosed. A connection pattern which is selected as a first connection pattern among connection patterns connected to panel contact pads does not reach a cutting line and is confined within a product region. As a consequence, the connection pattern selected as the first connection pattern may be prevented from being exposed on a cutting section along the cutting line, and thus, may be prevented from being changed in its electrical property due to penetration of moisture.
