    Abstract: A pixel includes a first transistor having a first electrode connected to a first node, a second electrode connected to a second node, and a gate electrode connected to a third node. The pixel further includes second and third transistors and first and second capacitors. The second transistor is connected between a data line and the third node and has a gate electrode electrically connected to a first scan line. The third transistor is connected between a first power source line connected to a first driving power source and the first node, and has a gate electrode electrically connected to an emission control line. The first capacitor is connected between the first node and the third node, and the second capacitor is connected between the second node and the third node. A light emitting element is connected between the second node and a second power source line.

    IPC: G06F3/044

    Abstract: In an inspecting method of a display device, the method includes: receiving an analog voltage from an external device; generating a first touch driving signal having a first potential based on the analog voltage; acquiring first raw data for each channel of touch electrodes by supplying the first touch driving signal to the touch electrodes; generating a second touch driving signal having a second potential higher than the first potential by using a charge pump; acquiring second raw data for each channel of the touch electrodes by supplying the second touch driving signal to the touch electrodes; calculating a ratio between the first raw data and the second raw data; and determining the charge pump is normal, based on the calculated ratio being within a designated range.
