Abstract:
1. An image display device comprising: a plurality of light emitting elements; a light modulator comprising a plurality of light valves modulating light directed thereto; a plurality of data electrodes for applying data voltages to said light valves; a control circuit comprising circuits connected to said light emitting elements and light valves and a timing sequence that generates and applies recurring control signals on said light emitting elements and said light valves according to said timing sequence; said timing sequence comprising: a recurring signal period comprising a first signal that sets a light valve to a transmission state and a subsequent second signal that decreases the transmission level of said light valve; a third signal decreasing the light intensity of the light emitting element illuminating said light valve, wherein said third signal is no later than said first signal; a fourth signal to increase the light intensity after said second signal; wherein no intervening signal cycle between said third and fourth signals that increases and later decreases the light intensity of said light emitting element; wherein no intervening signal cycle between said first and said second signals that decreases and subsequently increases the transmission of said light valve; no intervening signal cycle between said second and said fourth signals that increases and subsequently decreases the transmission of said light valve; wherein said timing sequence further comprises a fifth signal setting said light valve to the black state that inhibits light transmission; wherein in a cycle ending at said second signal, said fifth signal setting said light valve to the black state precedes said first signal; wherein the time interval between said third and said fourth signals is shorter than the time interval of two image frames.
