Abstract
A method for operating a bidirectional display comprising a substrate, on which a display array consisting of a multiplicity of light-generating image elements and a sensor array consisting of a multiplicity of light-detecting elements are formed, each light-detecting element being assigned at least one light-generating image element, and each light-detecting element having at least a photodetector, a reset switch, a transfer switch, a memory and a select switch. The exposure phase of a light-detecting element between two successive readout phases of the light-detecting element is in this case subdivided into at least two exposure subphases chronologically separated from one another, and the at least one light-generating image element assigned to the light-detecting element is activated at least temporarily between the two exposure subphases of the light-detecting element.
