Disclosed are a source driver capable of achieving high speed and high resolution and a display driving circuit including the same. The source driver may include: a first channel group and a second channel group configured to output source driving signals; a first gradation voltage divider configured to generate first gradation voltages using gamma reference voltages and provide the first gradation voltages to the first channel group; and a second gradation voltage divider configured to generate second gradation voltages having the same level as the first gradation voltages using the gamma reference voltages, and provide the second gradation voltages to the second channel group. The first and second gradation voltage dividers are connected to a gamma reference voltage generator configured to provide the gamma reference voltages, and receive the gamma reference voltages having the same voltage range from the gamma reference voltage generator.

Source driver and display driving circuit including the same

Disclosed is a driver for a display device, which is improved to stably sense pixels. The driver includes a multiplexer configured to output the sensing signal of a first input stage or second input stage, a first switch configured to switch a connection between an odd channel and the first input stage, a second switch configured to switch a connection between an even channel and the second input stage, and a switching circuit configured to switch a connection between a common power line and the first input stage or the second input stage.

Driver for display device

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.

Flexible circuit board for display

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.

Display device, and source driver and packet recognition method thereof

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.

Source driver including sensing circuit and display device using the same

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.
