  • Patent number: 10700136
    Abstract: A pixel structure and an organic light emitting display are disclosed. The pixel structure includes a plurality of pixels which includes a plurality of sub-pixels. At least one pixel forms a pixel unit, and longitudinally adjacent pixel units are arranged in a vertical mirror image, and/or laterally adjacent pixel units are arranged in a horizontal mirror image. The present disclosure may increase the area of mask opening during evaporation, reduce the difficulty of mask production process, and reduce the evaporation process difficulty by a reasonable pixel arrangement structure and allowing sub-pixels of adjacent pixels to share one mask opening to evaporate. It does not need to preset a gap during evaporating the sub-pixels of adjacent pixels of the mask, thereby a real high PPI is achieved while keeping the opening ratio. In addition, the present disclosure can further increase the strength of the mask.

  • Publication number: 20200090679
    Abstract: A device for preventing cables against external damage based on sound source localization comprises a power supply unit, and a sound source sensor unit, a camera unit, a signal processing unit and a wireless communication unit which are electrically connected to the power supply unit. The signal processing unit is connected to the sound source sensor unit, the camera unit and the wireless communication unit. The camera unit is associated with the sound source sensor unit. When the sound source sensor unit recognizes a target signal, the signal processing unit sends a trigger signal to the camera unit, and then the camera unit is triggered to replay a surveillance video to determine whether or not a target really exists. Compared with the prior art, the device has the advantages of being good in safety, high in reliability and the like.

  • Publication number: 20170356079
    Abstract: The present invention provides a linear evaporation source, comprising: a heating chamber for containing a vapor deposition material, a mixing chamber located above the heating chamber and used to mix the vapor deposition material vapor, and a channel used to communicate the heating chamber and the mixing chamber, wherein one end of the mixing chamber communicates with the heating chamber through the channel, and the other end is provided with a plurality of nozzles for spraying the vapor deposition material vapor; and heaters are provided at peripheries of the heating chamber, the mixing chamber, the channel and the nozzles. The linear evaporation source of the present invention can control the thickness of the vapor deposition film to have a better uniformity, because the heating of the vapor deposition material and the mixing of the material vapor are conducted in two independent spaces.

  • Patent number: 9728588
    Abstract: A pixel structure for OLED display is disclosed. The pixel structure includes multi-row pixel unit groups, each pixel unit group includes a plurality of pixel units arranged repeatedly in sequence, and each pixel unit includes a first sub pixel, a second sub pixel and a third sub pixel, wherein the same sub pixels of the pixel units in adjacent two rows are arranged in dislocation in a horizontal direction. The pixel structure can widen the distance between the corresponding openings of the sub pixels when making the corresponding metal mask to enhance the strength of the metal mask that a pixel unit of a smaller size can be produced under the consideration of process condition, so as to improve the resolution of the OLED display.
