  • Patent number: 7070269
    Abstract: An apparatus and method for recording an image using a transfer-type recording mechanism are such that a layer of an intermediate transfer element is removably formed on a surface of an intermediate transfer medium. The intermediate transfer element includes an ultraviolet stabilizer and a powder mixture. The intermediate transfer layer is capable of being dissolved and swelled by applying an ink liquid on the intermediate transfer medium and enables a viscosity of the ink liquid residing thereon to be increased. An image is produced on the intermediate transfer medium by supplying the ink liquid thereon. The image is then transferred to the recording medium, so that a high quality image is produced without any blurring, mixing or penetration of the ink liquid.

  • Publication number: 20060109025
    Abstract: A testing method for an array substrate is disclosed which includes a first measuring step of operating a line electrode driver circuit 15 and a row electrode driver circuit 16 like in a normal display mode while implementing writing in/reading out of a test video signal to and from supplemental capacitors 13, and a second measuring step of implementing writing in/reading out of the test video signals to and from a video bus 163 while rendering TFTs 11 of a pixel section 18 and analog switches 162 of the row electrode driver circuit 16 to be held turned off. Obtaining a difference between a measured result of the first measuring step and a measured result of the second measuring step allows only a pixel component and a row electrode component with no driver component to be derived, whereupon discrimination is implemented for the presence of or the absence of electric defects in the pixel section.

  • Patent number: 6630840
    Abstract: Each of analogue switches (ASW1 to ASWn) enters a non-conductive state (namely, Off state) by using two kinds of off-voltages Vbs which are different voltages. In this state, a test signal stored in a supplemental capacity (13) is kept during a desired time period and then red it. The waveforms of the two test signals corresponding to the two kinds of the off-voltages Vbs are compared to each other. By using the comparison result, it is possible to detect a presence of off-leak defect in an array substrate fabrication process and to easily distinguish the off-leak defect from other types of defects.
