    Abstract: A touch detection module includes driving electrodes extending parallel to each other, sensing electrodes crossing the driving electrodes, and a touch driver circuit for supplying touch driving signals to the driving electrodes and for detecting touch sensing signals through the sensing electrodes to determine touch position coordinates. The touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame. According to the group driving scheme, the touch driver circuit sorts the driving electrodes into groups, simultaneously drives driving electrodes in a same group among the groups, and drives the groups at different times. According to the sequential driving scheme, the touch driving circuit sequentially drives the driving electrodes.

    Abstract: A design for a scan driver and a display device including the scan driver that is more resilient to electrostatic discharge. Thin film transistors within a stage are designed differently depending on whether or not a gate of the transistor is connected to an external source. Transistors whose gate is connected to an external source is specially designed to withstand electrostatic discharge applied to the gate thereof by one or more of increasing a number of channel areas, decreasing a length of an ohmic bridge, including a resistive element to the gate, decreasing a width of a channel areas, and increasing a width of the active layer.

    Abstract: A display device including: a first substrate including a first base substrate and a lower pad disposed on one end of the first base substrate on a side; a second substrate disposed above the first substrate and including a second base substrate and an upper pad disposed on an end of the second base substrate on the side; a side pad electrically connected to the lower pad and the upper pad; and a sealing member disposed between the first substrate and the second substrate. The sealing member includes an insulating resin and conductive balls dispersed in the insulating resin, and the upper pad and the lower pad are electrically connected to each other through the conductive balls.
