  • Patent number: 11296139
    Abstract: An array substrate for a digital X-ray detector, and an X-ray detector including the same are disclosed, which reduce or minimize a contact resistance between a bias electrode and a PIN diode, and also improve a fill factor of the PIN diode. In the array substrate, a dual bias electrode in which a second bias electrode formed of a transparent conductive material is connected to a first bias electrode that is additionally connected to an upper electrode of the PIN diode, such that total resistance of the bias electrodes is reduced and a line width of the first bias electrode formed of a non-transparent material is reduced, resulting in an increased fill factor of the PIN diode.

  • Patent number: 11209557
    Abstract: An array substrate for a digital X-ray detector, a digital X-ray detector including the same, and a method for manufacturing the same are disclosed. The array substrate reduces a step difference of a PIN diode, removes a bent part from a lower part to reduce characteristic deterioration of the PIN diode, and increases the size of a formation region of the PIN diode to increase a fill factor. To this end, the array substrate allows a source region of an active layer included in a thin film transistor to be in surface contact with a lower electrode of the PIN diode, and disposes the lower electrode over a planarized source region or a base substrate, such that a step difference of the PIN diode is reduced and fill factor is improved.

  • Patent number: 11199635
    Abstract: A digital X-ray detector, a digital X-ray detection device and a manufacturing method thereof are discussed. The digital X-ray detector includes a base substrate including an active region including a plurality of pixel regions, and a gate-in-panel (GIP) region as at least one side region to the active region; a PIN diode disposed in the active region and over the base substrate; a GIP driver disposed in the GIP region and over the base substrate; and a scintillator layer disposed over the PIN diode and the GIP driver so as to overlay the active region and at least a portion of the GIP region. In the present invention, damage of the driver due to X-ray is minimized while a bezel size is minimized.

  • Patent number: 10707251
    Abstract: An array substrate for a digital X-ray detector and the digital X-ray detector including the same are disclosed. The array substrate effectively protects a PIN diode from external moisture or water, maximizes a light transmission region of a PIN diode, and reduces resistance by maximizing the region of a bias wiring. To this end, a closed-loop bias electrode formed to cover a circumferential surface of a PIN diode is used. In detail, the bias electrode includes a closed loop portion and a contact extension portion. The contact extension portion extends from one end of the closed loop portion so as to directly contact an upper electrode, and includes a hollow part therein.
