摘要:
A photoconductive target having a transparent electrode (102) and a photoconductive layer (103) on a transparent substrate (101) is disposed opposite to a plurality of integrated electron emitters having electron emitters (106) and gate electrodes (104). A plurality of electron emitters applying electron beams to the photoconductive target are temporally changed over by an electron emitter selector circuit (107) and a gate selector circuit (108). Thereby, signal charge generated and stored in the photoconductive layer is read. A time-series electric signal corresponding to a spatial distribution of the incident light is generated. A thin imaging apparatus suitable for a larger area is thus provided.

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.

摘要:
An active matrix liquid crystal display is disclosed in which a better image quality is obtained by specifying a relation between voltages (V S , V DMAX ) applied to the liquid crystal display. Also, a better holding characteristic is obtained by selecting the channel resistance R OFF of a thin film transistor (1) in its OFF state to be not smaller than 10¹²Ω.
摘要:
A liquid crystal display panel and a method of driving the display panel are disclosed. The display panel and the driving method can reduce the leakage of a gate driving voltage to a first pixel electrode (9) due to the parasitic capacitance of a thin field transistor (4), and can lessen an adverse effect of noise which is generated at a second pixel electrode by cancelling out the capacitive coupling to the first pixel electrode, on an image displayed by the display panel.

An image display displays image data on an image display part constructed by a display pixel array (18). A moving image signal output circuit (43) and a still image signal output circuit (41) output image signals to the display pixel array (18), and they are provided as circuit configurations independent of each other.
