摘要:
A method of utilizing a thin film device as a photosensor. The thin film device comprises a substrate upon which is deposited a charge transport layer, first and second injecting electrodes in low electrical resistance contact with the charge transport layer, the injecting electrodes being laterally spaced from one another, a gate electrode spaced normally from the first and second injecting electrodes and located opposite the first injecting electrode, for controlling injection therefrom, and laterally offset from the second injecting electrode, and a gate dielectric layer separating the gate electrode from the first and second injecting electrodes and the charge transport layer. The method of utilization comprises applying a first electrical bias of a first magnitude to the first injecting electrode, applying a second electrical bias of a second magnitude to the second injecting electrode, inhibiting charge injection from the first injecting electrode by applying a third electrode bias to the gate electrode of a third magnitude, and illuminating the charge transport layer. The photosensor may be selectively operated in a unity gain mode or in a variable gain mode, wherein said unity gain mode is achieved by causing the second magnitude to be greater than the first magnitude and the variable gain mode is achieved by causing the second magnitude to be less than the first magnitude.
摘要:
A thin-film structure on an insulating substrate includes an array of binary control units with an area of at least 90 cm.sup.2 and a density of at least 60 binary control units per cm. One implementation has an area of approximately 510 cm.sup.2, a diagonal of approximately 33 cm, and a total of approximately 6.3 million binary control units. Each binary control unit has a lead for receiving a unit drive signal, to which it responds by causing presentation of a segment of images presented by the array. Each binary control unit can present a segment with either a first color having a maximum intensity or a second color having a minimum intensity. Each binary control unit's unit drive signal causes the binary control unit to present its first and second colors. The substrate can be glass. Each binary control unit can include an amorphous silicon thin-film transistor (TFT) and a storage capacitor. Each binary control unit can be square. The thin-film structure can be used in an active matrix liquid crystal display (AMLCD), monochrome or, with an appropriate filter, color.

Light emitting devices including sub-pixels having different numbers of emissive layers are provided. At least one sub-pixel of a first color may include a single emissive layer, and at least one sub-pixel of a second color may include multiple emissive layers disposed in a vertical stack. Light emitting devices in which different voltages are applied to each sub-pixel or group of sub-pixels are also provided. In some configurations, the voltage to be applied to a sub-pixel may be selected based upon the number of emissive layers in the sub-pixel.
