  • 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.

  • Patent number: 7944145
    Abstract: A character display module comprises a character organic light emitting diode panel, a printed circuit which is electrically connected to the character organic light emitting diode panel, a drive controller which is disposed on the printed circuit board to drive and control the character organic light emitting diode panel, and a frame which is used to position the character organic light emitting diode panel on the printed circuit board. Therefore, such an arrangement provides a lighter, thinner, high quality, cost-saving and energy-saving character display module.
