    摘要: The optical proximity detector (10) comprises a flexible substrate (1) on which a plurality of light sources (6) and photodetectors (8) are arranged, consisting of thin, flexible layers of organic semiconductors (3.1, 3.2) and transparent electrodes (2.1, 2.2, 4.1, 4.2). The light sources (6) emit continuous or pulsed light (7) through the transparent electrodes (2.1, 2.2, 4.1, 4.2). An object (9) close to the light-emitting surface of the detector (10) partially reflects this light (7), and a fraction of it reaches an adjacent photodetector (8) that converts this light into an electrical signal. This signal contains information about the proximity of the object (9), and the information can be extracted with an electronic circuit that is either measuring the amount of detected continuous light or demodulating the detected light pulses.
