Abstract:
A spatially non-uniform electrode structure is proposed for controlling a spatially non- uniform electric field driving a tunable liquid crystal lens. The spatially non-uniform electrode structure enables the generation of a predetermined spatially non-uniform electric field profile where complex capacitive coupling between multiple different electrically floating neighboring electrode segments is employed for the generation of the electrical field of desired form by supplying an initial electric potential to a limited number of electrodes.
Abstract:
Gate lines are formed on an insulating substrate, and data lines crossing the gate lines are formed. The gate lines and the data lines are insulated from each other and intersect each other to define pixel areas. A thin film transistor including three terminals of a gate electrode, a source electrode and a drain electrode is formed in each pixel area. A direction control electrode and a pixel electrode are also formed in each pixel area. The thin film transistor switches the direction control electrode. The pixel electrode is electronically floating and capacitively coupled with the direction control electrode.
Abstract:
A display device according to an exemplary embodiment of the present inventive concept includes: a substrate (110); a data line (171), a gate line (121) and a thin film transistor disposed on the substrate (110); a common electrode (270) and a pixel electrode (191) disposed on the thin film transistor and overlapping each other with an insulating layer (250) interposed therebetween; a roof layer (360) formed to be separated from the pixel electrode (191) and the common electrode (270) so to form a microcavity (305) therebetween, the roof layer (360) having an injection hole (307) partially exposing the microcavity (305); a liquid crystal layer (310) filling the microcavity; an overcoat (390) formed on the roof layer (360) to cover the injection hole (307) and to seal the microcavity (305). The pixel electrode (191) includes an auxiliary electrode (193) that is formed on the data line (171), the auxiliary electrode overlapping and being insulated from the data line (171).
