NOVELTY - The structure (100) has a base board (2) divided into a set of regions (21). A set of filtering and sensing modules (4) is distributed on the regions, where the number of filtering and sensing modules is greater than ten. A non-organic filtering element (3) e.g. patterns of silts, filters first magnetic wavelength to obtain second electromagnetic wave. An electromagnetic sensor e.g. solar sensor, is placed under the non-organic filtering element for receiving the second electromagnetic wave. An electron/hole collecting module (5) is electrically connected to the electromagnetic sensor.    USE - Distributed filtering and sensing structure for use in an optical device e.g. image display device, solar cell (all claimed), LCD device, plasma display device, organic-LED display device, LED display device, liquid crystal on silicon (LCOS) display device and touch control display device, for conducting video telephone communication by a user at different places. Can also be used for digital light processing (DLP) display device, dot matrix display (DMD) device and a surface-conduction electron emitter display (SED) device.    ADVANTAGE - The structure has non-organic material such as metallic material, to fabricate the filtering element for prolonging operation life of the electromagnetic filtering element, thus preventing the electromagnetic sensor from being damaged by receiving the electromagnetic waves or charged particles, and hence assuring the distributed filtering and sensing structure or the optical device containing the distributed filtering and sensing structure to be operated normally. The material forming the electromagnetic filtering element by etching techniques can be used to form different patterns such as slits, holes and meshes, desired by the electromagnetic filtering element, thus providing simple manufacturing process.    DETAILED DESCRIPTION - The material forming non-organic filtering element comprises metallic material. An INDEPENDENT CLAIM is also included for an optical device comprising a distributed filtering and sensing structure.
