WIPO Patent Application WO/2023/195334
Kind Code:
A1
Abstract:
A display/input device 1 comprises: a positive electrode 20 disposed below an operation input surface 30 which is approached or touched by a detection target; a negative electrode 22 disposed so as to face the negative electrode 20; an organic EL layer 21 which is sandwiched between the positive electrode 20 and the negative electrode 22, and which serves as a light emitting unit for emitting light in accordance with a current flowing between the positive electrode 20 and the negative electrode 22; and a control unit 8 which has a light-emission mode for causing the organic EL layer 21 to emit light, and a detection mode in which the positive electrode 20 serves as a detecting electrode for detecting the approach or touch of the detection target, wherein, in the detection mode, the control unit 8 performs first control to open the negative electrode 22, or second control to make the positive electrode 20 and the negative electrode 22 have the same potential.
