Abstract

A display device includes: a power supplying unit which outputs at least one of a high-side output potential and a low-side output potential; a display unit in which pixels are arranged in a matrix and which receives power supply from the power supplying unit; a monitor wire arranged along a column direction of the pixels in the matrix, which has one end connected to at least one pixel inside the display unit, and is for transmitting the high-side potential to be applied to the pixel; and a voltage regulating unit connected to the other end of the monitor wire, which regulates at least one of the high-side output potential and the low-side output potential to be outputted by the power supplying unit, to set a potential difference between the high-side potential and the low-side potential to a predetermined potential difference.

First claim

The invention claimed is:

1. A display device, comprising:
a power supply configured to output at least one of a high-side output potential and a low-side output potential;
a display in which pixels are arranged in a matrix and which receives power from the power supply;
a detecting line which is arranged along a row direction or a column direction of the pixels arranged in the matrix, has one end connected to at least one of the pixels inside the display, and is for transmitt…
