摘要： A display device includes a display panel and a first sensor configured to sense a position of a touch of a user and a second sensor configured to sense a pressure of the touch. The first sensor and the second sensor may be provided inside or surrounding an area of the display panel. The second sensor includes a first conductor, a second conductor spaced apart from the first conductor, and configured to form capacitance with the first conductor, and one or more variable resistance elements connected with the first conductor.

摘要： A display device includes a touch panel and a display panel. The touch panel outputs touch sensing signals. At least one of a plurality of touch sensing signals is converted from a time domain to a frequency domain, and then information on a thickness of a common electrode is detected based on a peak of the converted touch sensing signal. As a result, it is possible to inspect whether the common electrode is formed with a uniform thickness without destroying the display device.
