摘要： A pixel device is provided, which comprises: (A) an electrochemical transistor device with a source and a drain contact; a gate electrode; an electrochemically active element arranged between, and in direct electrical contact with, the source and drain contacts, which electrochemically active element comprises a transistor channel and is of a material comprising an organic material having the ability of electrochemically altering its conductivity through change of redox state thereof; and a solidified electrolyte in direct electrical contact with the electrochemically active element and the gate electrode and interposed between them in such a way that electron flow between the electrochemically active element and said gate electrode(s) is prevented; whereby flow of electrons between source contact and drain contact is controllable by means of a voltage applied to said gate electrode(s), and (B) an electrochromic device comprising: an electrochromic element comprising (i) a material that is electrically conducting in at least one oxidation state and (ii) an electrochromic material, wherein said materials (i) and (ii) can be the same or different; a layer of a solidified electrolyte which is in direct electrical contact with said electrochromic element; and two electrodes adapted for application of a voltage therebetween; each of said electrodes being in direct electrical contact with a component selected from said electrolyte layer(s) and said electrochromic element, in which pixel device one of said source and drain contacts of the electrochemical transistor device A is in electrical contact with one of the electrodes of the electrochromic device B. Also provided are matrices of such electrochemical pixel devices, and pixelated displays incorporating the matrices. A process for the production of an electrochemical pixel device is also provided.
