  • Patent number: 11963385
    Abstract: The disclosure provides a local stretch packaging structure, including a substrate, a flexible electronic element, a plurality of light-emitting display elements, and a packaging layer. The flexible electronic element is disposed on the substrate. These light-emitting display elements are disposed on the flexible electronic element. The packaging layer includes a packaging area and a non-packaging area. The packaging area covers the upper surface and sidewalls of these light-emitting display elements. The non-packaging area is directly covered the flexible electronic element that is not disposed with these light-emitting display elements.

  • Patent number: 7977870
    Abstract: An organic light emitting display (OLED) pixel structure is provided to improve the resolution of an OLED without significantly changing the current OLED manufacturing process. With a novel pixel arrangement and circuit layout, an organic light emitting material is evaporated onto a substrate through a mask and thus a plurality of sub-pixels are formed simultaneously while enabling each sub-pixel to correspond to different pixels. Therefore, the area of each sub-pixel is reduced and the resolution of a display is increased.

  • Patent number: 7491592
    Abstract: A thin film transistor device with high symmetry is disclosed, in which the symmetrical structure of transistor is utilized to enable currents flowing in the channels of each transistor formed on a polysilicon film of a specific crystallization direction to pass the same amount of grain boundaries, thereby improving the uniformity of electrical characteristics of the device. By the thin film transistor device of the invention, not only the freedom of circuit design is increased, but also the circuit area of a TFT device occupied is reduced.

  • Publication number: 20070176170
    Abstract: The present invention relates to an organic light-emitting device with an integrated color filter and a method for manufacturing the same. The organic light-emitting device is manufactured with a metal layer depositing process for raising the source/drain layer so that the sidewall area of a pixel electrode formed in a contact hole is reduced and thus the contact resistance of the pixel electrode is decreased for reducing power loss. Moreover, since the sidewall of the contact hole formed by the method of the invention is not overly abrupt, the breaking or cracking of the portion of the pixel electrode formed in the contact hole can be prevented.

  • Patent number: 6639420
    Abstract: A new method to test multiple integrated circuit device designs using a single, probe card design is achieved. The method compriseproviding a plurality of integrated circuit device designs each having a probe pad array comprising a fixed pitch. A first integrated circuit device having a first design is loaded on a probing stage. The first integrated circuit device is probed using a vertical probe card comprising a probe tip array. The probe tip array comprises the same fixed pitch. An automated tester is thereby coupled to the first integrated circuit device. The first integrated circuit device is tested with the automated tester. The steps of loading, probing, and testing are repeated on at least one other integrated circuit device having a differing design than the first integrated circuit device.
