Abstract:
1. A display comprising: a data electrode for delivering input data; a scan-power electrode; said scan-power electrode delivering at least a first signal and a second signal in operating said display; a reference voltage source; a pixel disposed at the intersect of said scan-power electrode and said data electrode; said pixel comprising: a light emitting element; wherein said light emitting element emits light according to an electrical current supplied thereto; a storage element for holding data information having a first and a second ends; a control circuit being connected to said data electrode, at least a scan-power electrode, said storage element, and said light emitting element; said control circuit comprising a switching element having a high-impedance control terminal, a second terminal, and a third terminal; said high-impedance control terminal being a gate or a base of a transistor; said control terminal is connected to the first end of said storage element; said control circuit writing said data information from said data electrode to said storage element during the period when said first signal is applied to said scan-power electrode; said control circuit, in response to said second signal delivered via the same said scan-power electrode, inhibits data transfer between said data electrode and said storage element when said second signal is applied to said scan-power electrode; wherein said control circuit further comprising a conducting channel for conducting electrical current between said scan-power electrode (S 1 ) and said voltage source via said light emitting element; wherein, in operation of said display, said conducting channel is enabled by applying a drive voltage on said scan-power electrode (S 1 ), and wherein said conducting channel, when enabled, is modulated by said data information through said switching element of said control circuit; wherein, in operation of said display, said conducting channel is inhibited by applying a disabling signal on said scan-power electrode (S 1 ); and wherein said light emitting element is turned off when said conducting channel is inhibited; wherein said conducting channel, when enabled, comprises at least a direct current path not ended on a capacitor in said pixel; wherein, in operation of said display, said enabling and inhibiting operation of said conducting channel are controlled in its entirety by (1) said drive voltage and said disabling signal applied to said scan-power electrode and (2) said modulation by said data information through said switching element when said conducting channel is enabled.
