摘要： A display device comprising a number of light emitting diodes disposed in a matrix array, a switching element being connected in series with each of the horizontal (row) and the vertical (column) scanning lines; said array being scanned in such a manner that the column lines are scanned with a pulse consisting of a negative part and a subsequent positive part while the row lines which are always biased with a negative voltage of a value smaller than that of the said negative part of the column scanning pulse are scanned with a negative pulse of a value larger than that of the said negative part of the column scanning pulse, a trigger pulse being applied to the gate electrode of the switching elements in synchronization with the column scanning pulse for a column which includes a light emitting diode to be energized, thus a light emitting diode which has been transferred to a conductive state being returned to the non-conductive state by the negative part of the column scanning pulse just before the relevant column is scanned for the second time, a bright display being thereby ensured.

摘要： A solid-state imaging device comprises a scanner IC having a two-dimensional matrix of switching transistors (17), on top of which are deposited a photoconductive film (28) and a transparent electrode (31). The photoconductive film is deposited (29) through an opening (25) in a shield plate or mask plate (26), so that it is not deposited over a scanning shift register (16). The transparent electrode (31) is then formed on top of the photoconductive film, either through the same or a different shield plate, or by photo-etching. Voltages applied to the transparent electrode (31) therefore do not affect the shift register (16).

摘要： In the method of producing photoelectric transducers which method having processes for forming a photoconductive layer on a predetermined substrate which has an irregular surface. The method includes depositing the photoconductive layer in an atmosphere including at least plasma, the predetermined substrate with irregular surface being disposed above a first electrode to which an electrode is opposed, and said photoconductive layer is formed while a negative potential is applied to the first electrode. This enables the photoconductive layer to be formed without breaks or steps, pinholes and so on due to the irregular surface, and therefore, it is possible to provide good photoelectric transducers having a small dark current.

摘要： A thin film phototransistor comprises a source electrode (6), a drain electrode (7), a gate electrode (2), a gate insulating film (3), and a semiconductor layer (4), having no overlapped region between the. gate electrode (2) and the source electrode (6) and/or between the gate electrode (2) and the drain electrode (7). Such a phototransistor has (1) a function as a photosensor and a switching function, (2) a high input impedance, (3) a voltage control function, and (4) a high photocurrent ON/OFF ratio. This thin film phototransistor can be used independently or together with a thin film transistor for picture elements of a one-dimensional or two-dimensional photosensor array, producing satisfactory results.
