    摘要: A driving circuit drives a display panel having a matrix of picture elements and electrodes. The driving circuit includes a memory storing compensation data for compensating for position-dependent brightness differences between the picture elements. The brightness differences are due to the stray resistance and capacitance of the picture elements and electrodes. A correction circuit modifies image data according to the compensation data to generate control signals, which are used to control drivers that drive the picture elements via the electrodes. The modified image data produce a display with an even average brightness over the entire display panel.

    摘要: In an image display system using an organic EL element, variation of light intensity of pixels on a display panel due to variation of characteristics of a bias transistor for energizing said EL element is improved. An active layer of said bias transistor is formed by polysilicon, and length and width of a gate of said transistor is at least 10 times as large as average diameter of a crystal grain of polysilicon in said active layer.

    摘要: A MOS-FET transistor is produced on a substrate made of glass which has a non single crystal semiconductor film (2'). The average diameter of a crystal grain in said film is in the range between 0.5 times and 4 times of thickness of said film, and said average diameter is 250 .ANG.-8000 .ANG., and said film thickness is 500 .ANG.-2000 .ANG.. The density of oxygen in the semiconductor film (2') is less than 2.times.10.sup.19 /cm.sup.3. A photo sensor having PIN structure is also produced on the substrate, to provide an image sensor for a facsimile transmitter together with the transistors. Said film (2') is produced by placing amorphous silicon film on the glass substrate through CVD process using disilane gas, and effecting solid phase growth to said amorphous silicon film by heating the substrate together with said film in nitrogen gas atmosphere. The film (2') thus produced is subject to implantation of dopant for providing a transistor. The film thus produced has high mobility which provides high speed operation of a transistor, and low threshold voltage of a transistor.

    摘要: An image sensor (10) has a substrate (1), an active layer (3') having a source region and a drain region placed on said substrate (1), a gate insulation layer (4') placed on said active layer, and a gate electrode layer (5') on said gate insulation layer (4'). The active layer (3') is produced by the steps of producing amorphous silicon layer by using disilane gas (Si.sub.2 H.sub.6) through Low Pressure CVD process, and annealing said layer at 500.degree.-650.degree. C. for 4-50 hours in nitrogen gas atmosphere. The gate insulation layer (4') is produced through oxidation of the surface of the active layer at high temperature around 900.degree.-1100.degree. C. The oxidation process at high temperature improves the anneal process and improves the active layer. Thus, an image sensor with uniform characteristics is obtained with improved producing yield rate.
