An electrowetting display device is presented. The electrowetting display device includes a first support plate and a plurality of pixel walls over the first support plate. The plurality of pixel walls are associated with an electrowetting pixel. The display device includes a storage capacitor beneath the electrowetting pixel. The storage capacitor includes a first plate, a second plate, and a dielectric material having a variable relative permittivity. The dielectric material is disposed between the first plate and the second plate. The display device includes a controller configured to control the relative permittivity of the dielectric material to set a capacitance value of the storage capacitor. In embodiments, the dielectric material includes at least one of a transition metal dichalcogenide and a thin-film Barium Strontium Titanate (BST).
