  • Patent number: 11817519
    Abstract: A lower electrode of a PIN diode and a second protective layer covering the PIN diode are formed not using separate mask processes, but using the same mask process using the same mask, thereby reducing the number of mask processes and thus increasing process efficiency. Further, the lower electrode of the PIN diode is patterned and then the second protective film covering the PIN diode is patterned such that both the former patterning and the latter patterning are carried out using a single mask process, thereby reduce increase in defects due to foreign materials or stains.

  • Publication number: 20220210345
    Abstract: A digital X-ray detector includes a width of a data line or a gate line extending across a dummy pixel area is smaller than a width of the data line or the gate line extending across an active area, a width of a dummy gate line or a dummy data line extending across the dummy pixel area is smaller than a width of the gate line or the data line extending across the active area, so that static electricity generated during a manufacturing process does not randomly flow into the active area, but rather flows into the dummy pixel area having the lowest capacitance, and the static electricity may be guided not to the active area but to the dummy gate line or dummy data line in the dummy pixel area, thereby minimizing line defects or block luminance deviation defects caused by the static electricity generated during the manufacturing process.
