    摘要： A display device includes: a display panel including pixels for displaying a first color, a second color, a third color, and a fourth color; and a signal processor configured to convert an image signal including gradation data of the first to third colors into a first signal including gradation data of the first to third colors and a second signal including a gradation datum of the fourth color and output the first and second signals. When the gradation data of the image signal have the same value, output signals from the signal processor include an output signal in which the gradation data of the first signal and the gradation datum of the second signal have the same value and an output signal in which the gradation data of the first signal and the gradation datum of the second signal have values different from each other by 1.

    摘要： A detection device includes: optical sensors; switching elements, gate lines, and signal lines corresponding to the optical sensors; a detection circuit that is supplied with signals from the optical sensors through the signal lines; and a signal line selection circuit for switching a coupling state between the signal lines and the detection circuit. A drive signal is supplied to the gate lines row by row to bring the switching elements belonging to a predetermined row into a coupled state. The signal line selection circuit couples the signal lines to the detection circuit column by column in a predetermined order in a reading period of the predetermined row. A reset potential is supplied to the optical sensors and the signal lines belonging to the predetermined row after completion of the reading period of the predetermined row and before start of the reading period of a row next to the predetermined row.
