Title: Formation of image
Inventor: SAKAEDA MASATAKA
IPC: B41J2/44
Filed: 1986-03-19
Abstract: PURPOSE:To control the resolution of an image formed on a photosensitive material by disposing a light defector in an optical conduit for an exposing beam and varying an A.C. signal to be fed to said deflector from the outside. CONSTITUTION:A focus lens 3 focuses a laser flux 2 onto the surface of a drum of photosensitive material 4. When a signal is fed from a signal controller 6, the refractive index of a light deflector 5 disposed in an optical conduit for the laser flux 2 is varied to vary the travelling direction of the laser flux 2 continuously, i.e. vibrate. While the scanning by means of the laser flux 2 being performed, a semiconductor laser 1 is turned on, off to form an image, and when the signal to be fed to the light deflector 5 is varied for a random time interval during the formation of image, the resolution only at a random portion of the image can be varied. In other word, when a signal is fed to the light deflector from the outside so as to vary the travelling direction of an exposing beam, the resolution of image can be controlled.

Abstract: PURPOSE:To decrease off currents by shielding a semiconductor layer mainly consisting of the silicon of a transistor(TR) with the electrodes of the TR exclusive of its channel region, thereby attenuating or shielding the incident light from above with these electrodes. CONSTITUTION:A second non-single crystal silicon film 19 is completely coated with the source electrode 20 and drain electrode 21 and a first non-single crystal silicon film 17 exclusive of the channel region is also coated with the source electrode 20 and the drain electrode 21.

A light shielding film is usually provided on a counter substrate and may be provided on the upper layer of an insulating substrate 10. The incident light from the light source provided above this device is once shielded by the light shielding film and is partly transmitted there through or is repetitively reflected by the level difference of the film, by which the light is made incident on the semiconductor layer of the TFT. The semiconductor layer is, however, coated with the electrodes 20, 21 and, therefore, the incident light is fully or partly shielded.
