  • Publication number: 20230217759
    Abstract: A gate-in-panel (GIP) display panel and a device are discussed, which are capable of resolving an output deviation between shift clock lines disposed in a bezel area and easily achieving a narrow bezel. The display panel can include an active area configured to display an image, and a bezel area disposed around the active area. Further, a ground area, a clock line area, a GIP circuit area, and a low-voltage line area can be disposed in the bezel area, and the clock line area can be disposed closest to the active area.

  • Patent number: 9881555
    Abstract: Disclosed is an OLED display device capable of sensing and correcting a progressive bright point defect and a method of driving the same. The OLED display device includes a data driver for supplying an off-driving voltage to a driving transistor for driving a light emitting element in each sub-pixel, and sensing a voltage corresponding to a leakage current of the driving transistor, and a bright point estimator for estimating a progressive bright point of a sub-pixel by comparing a voltage value sensed through the data driver with a reference value, and darkening and correcting the sub-pixel estimated to have the progressive bright point.

  • Patent number: 9754538
    Abstract: Disclosed is a method of driving an organic light emitting display apparatus which, when a defective pixel where at least one organic light emitting diode (OLED) is not normally driven occurs in a plurality of pixels each including two OLEDs, changes input image data corresponding to a data voltage to be supplied to the at least one OLED by using a compensation value.

  • Publication number: 20010037620
    Abstract: Disclosed herewith is a built-up frame for supporting a portable water pool. The built-up frame is attached to the circumferential edge of the portable water pool. The built-up frame includes a plurality of fence rods each having a predetermined length. The fence rods are arranged one after another to form a polygonal shape. Each of the connectors has a through hole. Each pair of the connectors are fitted into the inner ends of two neighboring fence rods, and are overlapped together to be connected to each other at a predetermined angle. A plurality of support rods each have an upper end portion and at least one engaging projection projected from the upper end portion. Each of the support rods is inserted into and vertically supports two overlapped connectors. A plurality of tightening caps each accommodates the upper end portion of each of the support rods, and is each engaged with and disengaged from the upper end portion by rotating the cap by a predetermined angle regardless of direction.
