Patent number: 7172922Abstract: A “black” pixel for measuring dark current is produced using carbon-based or pigment-based black photosensitive resist deposited on a support layer that is formed using negative-tone photosensitive resist, both being formed over the light sensitive portion of the black pixel. After an array of pixels is fabricated, a negative-tone resist layer is deposited on the upper insulator formed over the pixels, and a region of the negative-tone resist located over the black pixel is exposed using a first mask. A carbon-based resist layer is deposited on the negative-tone resist layer, and a region of the carbon-based resist located over the black pixel is exposed using a second mask. The negative-tone and carbon-based resists are then developed to remove portions of the layers not located over the black pixel.Type: GrantFiled: August 19, 2002Date of Patent: February 6, 2007Assignee: Tower Semiconductor Ltd.Inventors: Almog Benjamin, Hanan Wolf, Eyal Shevartzberg

Patent number: 6269565Abstract: A viewing device for viewing transparencies comprising a display surface; a source of backlighting that backlights the display surface with linearly polarization axis; member for holding a transparency on the display surface;an optical sensor positioned so that it views the display surface; and polarizer, having a polarizer axis, and suituated between the display surface and the optical sensor. The viewing device is configured such that the polarizer axis is functionallu related to the polarization axis of the polarized light; and the polarized is smaller than the display surface.Type: GrantFiled: June 4, 1997Date of Patent: August 7, 2001Assignee: Smartlight Ltd.Inventors: Dan Inbar, Alex Natanzon, Hanan Wolf, Ben-zion Levi, Eran Shaffir

Patent number: 6178672Abstract: A method for viewing transparencies comprising backlighting a transparency with polarized light and viewing the transparency through a polarizer. Preferably, the polarization axis of the backlighting and the polarization axis of the polarizer are oriented at about 90 degrees to each other. The transparency is oriented so that a substantial amount of polarized backlighting passes through the transparency and the polarizer. Also disclosed are apparatus for viewing a transparency using polarized backlighting.Type: GrantFiled: October 30, 1997Date of Patent: January 30, 2001Assignee: Smartlight Ltd.Inventors: Dan Inbar, Giora Teltsch, Hanan Wolf, Eran Shaffir
