发明名称 Display substrate and display device
摘要 A display substrate comprising a plate, for example a glass plate, on which display elements, e.g. pixels comprising pixel electrodes and thin-film-transistors, and an acoustic transducer, e.g. a microphone, speaker or buzzer, formed from thin film layers over a cavity, are formed. The cavity may be provided by powderblasting through the depth of the glass plate. The display substrate with integrated acoustic transducer may be incorporated in a display device, e.g. a liquid crystal display device. Also described is a discrete acoustic transducer, comprising a plate of an insulating material, a cavity in the plate, a plurality of layers that have been deposited on the plate, and a moveable member formed from the deposited layers and positioned over the cavity.
