  • Patent number: 11955553
    Abstract: Embodiments disclosed herein relate to using an implantation process and a melting anneal process performed on a nanosecond scale to achieve a high surface concentration (surface pile up) dopant profile and a retrograde dopant profile simultaneously. In an embodiment, a method includes forming a source/drain structure in an active area on a substrate, the source/drain structure including a first region comprising germanium, implanting a first dopant into the first region of the source/drain structure to form an amorphous region in at least the first region of the source/drain structure, implanting a second dopant into the amorphous region containing the first dopant, and heating the source/drain structure to liquidize and convert at least the amorphous region into a crystalline region, the crystalline region containing the first dopant and the second dopant.

  • Patent number: 8513897
    Abstract: An OLED display with a current stabilizing device employs a current stabilizing device which is coupled between the driving-voltage line of the data driver and the data-power-supply wires to produce an output voltage higher than the driving voltage by boosting the driving voltage of the data driver, and then to maintain the current of the OLEDs at a constant level by performing current limiting, so that the problem of the current-ununiformity caused uneven luminance of the conventional OLED display can be solved, and the possibility that the luminance of the OLED panel will decay in a short period of time is reduce.

  • Publication number: 20120098809
    Abstract: An icon organic light emitting diode (OLED) display with high uniformity and increased brightness has a driving module, an OLED display module and multiple power control modules. The driving module is connected to the power control modules. The power control modules generate multiple direct current (DC) powers. The OLED display module has multiple OLED units having multiple non-identical shapes and sizes. Each OLED unit is driven by one DC power based on the shape and size of the OLED unit. The OLED units with different sizes and shapes are driven respectively by proper DC powers, thus increased brightness and high uniformity of the OLED display is achieved.

  • Publication number: 20120086626
    Abstract: A feedback structure for an organic light-emitting diode display comprises an organic light-emitting diode panel, a driver chip and a signal transmission line group. The organic light-emitting diode panel includes a signal input terminal group and a signal feedback term connected to the ground. The driver chip includes a power input port connected to an external power source, a signal input port, and a feedback port connected to the ground. The signal transmission line group is electrically connected between the signal input terminal group and the signal output port. By such arrangements, it can ensure a stable segment control signal or avoid damage to the driver chip.
