  • Publication number: 20190341527
    Abstract: Provided are a light emitting diode (LED) in which a conductive barrier layer surrounding a reflective metal layer is defined by a protective insulating layer, and a method of manufacturing the same. A reflection pattern including a reflective metal layer and a conductive barrier layer is formed on an emission structure in which a first semiconductor layer, an active layer, and a second semiconductor layer are formed. The conductive barrier layer prevents diffusion of a reflective metal layer and extends to a protective insulating layer recessed under a photoresist pattern having an overhang structure during a forming process. Accordingly, a phenomenon where the conductive barrier layer is in contact with sidewalls of the photoresist pattern having an over-hang structure and the reflective metal layer forms points is prevented. Thus, LED modules having various shapes may be manufactured.

  • Patent number: 9870733
    Abstract: A data signal processing device includes a load calculator and a compensation processor. The load calculator calculates an on-pixel rate (OPR) based on image data signals and positional weight values. The positional weight values are determined based on locations of pixels in a display panel. The OPR is proportional to a frame luminance load, which corresponds to a sum of driving currents for the pixels to emit light in each of a plurality of frames. The compensation processor compensates distorted luminance caused by the frame luminance load based on the OPR.
