Abstract
Embodiments of the present disclosure disclose a writable liquid crystal display device, a manufacturing method and a driving method thereof. The writable liquid crystal display device comprises a first substrate and a second substrate arranged opposite to each other, and a liquid crystal molecule layer located between the first substrate and the second substrate. A plurality of pixel units arranged in an array are disposed on the first substrate, and a pixel electrode is arranged in each pixel unit. A piezoelectric transducer connected with the pixel electrode is further arranged in each pixel unit. A surface plasma resonance metal layer is arranged on the pixel electrode. A pressure transfer structure is disposed between the first substrate and the second substrate. One end of the pressure transfer structure is in contact with the second substrate, and the other end of the pressure transfer structure is in contact with the piezoelectric transducer.
