  • Patent number: 10658441
    Abstract: A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. Each pixel may include organic layers interposed between an anode and a cathode. The organic layers may emit out-coupled light that escapes the display and waveguided light that is waveguided within the organic layers. A reflector may be placed at the edge of the organic layers to reflect the waveguided light out of the display. The reflector may be located within a pixel definition layer and may be formed from metal or may be formed from one or more interfaces between high-refractive-index material and low-refractive-index material. The reflector may be formed from an extended portion of the pixel anode. The reflector may be formed from light-reflecting particles that are suspended in the pixel definition layer.

  • Patent number: 8009131
    Abstract: A testing system of a liquid crystal display panel including a substrate, a driving circuit, a first testing pad, and a second testing pad is provided. The substrate includes a pixel array whose one side has a pixel testing area. The driving circuit is formed on the substrate and connected to the other side of the pixel testing area for providing a signal to the pixel array. The first testing pad is connected to the driving circuit. The second testing pad is connected to the pixel testing area. The testing method of the liquid crystal display panel includes: respectively testing whether the liquid crystal display panel and the pixel testing area have a defect and accordingly generating a first testing pattern and a second testing pattern; combining the first testing pattern and the second testing pattern to determine whether the defect occurs at the driving circuit or the pixel array.

  • Patent number: 7423447
    Abstract: A method for testing a liquid crystal display panel is provided. The gate drivers are integrated onto the panel. The method includes simultaneously inputting a clock signal, an inverted clock signal, and a pull down signal into clock signal, inverted clock signal, and pull down signal input ends of the gate drivers. Simultaneously input a start pulse into the start pulse input end of the gate drivers to simultaneously turn on the gate lines in the selected area and thus simultaneously turning on the pixels in the selected area. At the same time, input test signals to all the data lines. The method of testing liquid crystal display panels disclosed by the present invention may be performed separately by areas, in which the panel is divided into different sub areas and is tested one area at a time.

  • Patent number: 7199059
    Abstract: A method for removing polymer as an etching residue is described. A substrate with polymer as an etching residue thereon is provided, and a hydrogen-containing plasma is used to treat the substrate. A wet clean step is then performed to remove the polymer from the substrate. The treatment using hydrogen-containing plasma can change the chemical property of the polymer, so that the polymer can be removed more easily in the subsequent wet clean step.
