摘要:
In one embodiment, a display device having a touch function includes an insulating substrate and a plurality of pixels formed on the insulating substrate and arranged in a matrix of rows and columns. The pixels form a plurality of pixel blocks formed of a plurality of rows and columns of the pixels. A sensor circuit is arranged in a space between adjacent pixels on the insulating substrate and includes a coupling electrode, a detection electrode arranged adjacent to the coupling electrode for forming a coupling capacitance therebetween, and a reading-out circuit to read out a potential of the detection electrode. At least one sensor circuit is arranged in each pixel block. The contact or non-contact by a fingertip or a nib is detected by a potential difference of the detection electrode.
