<P>PROBLEM TO BE SOLVED: To stabilize operation of a display capable of input and output. <P>SOLUTION: In each pixel of an I/O display 1, light-emitting operation displaying images and light-receiving operation detecting light irradiated from the outside are performed. During the light-emitting operation, a switch 11 is conducted, an EL element 12 emits light, and charges are charged to a parasitic capacity 13. When the operation method is changed over, from the light-emitting operation to the light-receiving operation, during the light-emitting operation up to then, the charge charged to the parasitic capacity 13 is extracted, and then the light-receiving operation is performed. During the light-receiving operation, the switch 11 is nonconductive, and the light from the outside is detected, on the basis of leakage current generated by the EL element 12, according to the light being irradiated from the outside. The invention can be applied to displaying of images and to a display capable of detecting light from the outside. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
