Patent ID: 8350801

Claim:
A display apparatus for performing an image display operation and an image reading operation, the display apparatus comprising: a plurality of pixel sections, wherein: the plurality of pixel sections each include a light output section for outputting first light, and a light receiving section for receiving reflected light obtained as a result of an imaging subject being irradiated with the first light; the plurality of pixel sections are divided into a plurality of groups; each group includes the pixel sections so that each group contains a plurality of pixels; wherein pixel sections adjacent to each other belong to different groups; the light output section outputs the first light and the light receiving section receives the reflected light on a group-by-group basis; and the light output sections belonging to the same group output the first light at the same time and the light receiving sections belonging to the same group receive the reflected light at the same time; wherein among the plurality of pixel sections, the pixel sections belonging to the same group are located discretely from each other; and a control section for controlling a degree of discreteness between the pixel sections belonging to the same group in accordance with a scattering degree of the reflected light, wherein the degree of discreteness refers to how far the pixel sections belonging to the same group are apart from each other.
