Patent ID: 7956830

Claim:
An organic light-emitting diode (OLED) panel, comprising: a plurality of data lines, each data line selectively transmitting a compensation signal and a data signal; a plurality of scan lines, each scan line transmitting a scan signal, wherein two neighboring data lines and two neighboring scan lines crossing the two neighboring data lines, which define a plurality of pixels, and each pixel comprises: an organic light emitting diode; a driving transistor, having a control terminal, for controlling an amount of current passing through the organic light emitting diode; and a bias switch electrically connected to the data line and the control terminal of the driving transistor in response to the scan signal; a plurality of sampling voltage lines electrically connected to the pixels connecting to the same scan line, each sampling voltage line transmitting a compensation voltage in response to the compensation signals and threshold voltages of the driving transistors and the organic light emitting diodes; and a plurality of compensation voltage lines electrically connected to the pixels connecting to the same scan line, each compensation voltage line adjusting data signals in response to the compensation voltage.
