<p>In an active matrix local tunable oscillators (11) are provided as the respective driving means at each picture element (8), e.g. in displays with frequency dependent (optical) properties or effects (dielectrophoresis, dielectric anisotropy). Other applications are sound and vision systems like the singing display which has an acoustic transducer means. Different kinds of oscillators (relaxation oscillators, ring oscillators) may be chosen in which the tuning of frequencies is based on e.g. the variation of a current supplied to a capacitor.</p> |
