Abstract:
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 transmitting a high-side potential or a low-side potential to be applied to the at least one pixel; and a voltage regulator connected to the other end of the detecting line and configured to regulate at least one of the high-side output potential and the low-side output potential that are to be outputted by the power supply, to set any one of the following potential differences to a predetermined potential difference: a potential difference between the high-side potential and a reference potential; a potential difference between the low-side potential and a reference potential; and a potential difference between the high-side potential and the low-side potential wherein each of the pixels includes: the high-side potential is applied to one of the second electrode and the other of the source electrode and the drain electrode, the low-side potential is applied to the other of the second electrode and the other of the source electrode and the drain electrode, the display device further comprises: a first power source line and a second power source line, the first power source line electrically connecting the others of the source electrode and the drain electrode of the respective drivers of adjacent pixels in at least one of the row direction and the column direction, and the second power source line electrically connecting the second electrodes of the respective luminescence elements of adjacent pixels in the row direction and the column direction, the pixels receive the power supply from the power supply via the first power source line and the second power source line, and the detecting line is formed in the same layer as the first power source line, wherein the detecting line is separate from scanning lines and data lines of the display device.
