  • Patent number: 10797110
    Abstract: Imaging panels and imaging systems that may employ use organic photodiodes or other continuous sensors are discussed. The detector panels discussed may have a non-pixelated organic photodiode disposed above a pixelated backplane. In some embodiments, the sensor panels may also include dielectric structures that create buried vias in the region of contact between the organic photodiode and the thin film transistor (TFT) backplane. In some embodiments, the sensor panels may include dielectric structures that separate neighboring pixels. The dielectric structures may decrease thickness inhomogeneity in active areas of the organic photodiode. Detector panels discussed herein may have decreased sensing lag and current leakage, and improved reliability. Methods for formation of organic photodiodes and of dielectric structures are also discussed.

  • Publication number: 20170062144
    Abstract: A process for forming a capacitor is presented. The process includes providing a laminate including a dielectric layer disposed on a sacrificial substrate, forming a free-standing metallized dielectric layer and packaging the free-standing metallized dielectric layer to form a capacitor. The dielectric layer includes a polyetherimide. The step of forming the free-standing metallized dielectric layer is performed by: (a) disposing a metal layer on the dielectric layer to form a metalized laminate such that a metalized dielectric layer is formed on the sacrificial substrate, and removing the sacrificial substrate to form the free-standing metallized dielectric layer; or (b) removing the sacrificial substrate from the laminate to form a free-standing dielectric layer, and disposing a metal layer on the free-standing dielectric layer to form the free-standing metallized dielectric layer. A capacitor formed by the process is presented.

  • Patent number: 9405150
    Abstract: The present disclosure relates to a technical field of display, and discloses a backlight module fitting platform. The backlight module fitting platform includes a primary platform and a number of first supporting pads located at a surface of the primary platform for supporting the backlight module. The backlight module fitting module further includes a lifting mechanism connected to the first supporting pad and supporting each of the first supporting pads to rise and fall independently. According to the backlight module fitting platform of the present disclosure, independent rise and fall of each of the first supporting pads is adjusted via the lifting mechanism so that the backlight module fitting platform is adapted for fitting of even-back and uneven-back backlight modules and can stably support and fit the backlight modules.
