Abstract: A row-select circuit (118) for an organic light emitting diode display (116) propagates a gating pulse through a shift register. This gating pulse is synchronized with a system clock signal and is used to selectively apply a plurality of broadcast control signals to a selected row of pixels on the display (116). The line scanning circuitry (118) is controlled to clear and autozero the pixels in the display (116) either on line at a time or the entire image frame at a time. According to another aspect of the invention, the clearing of a row of pixels in the display (116) is performed over several line intervals before the row is autozeroed and loaded with new values. According to yet another aspect of the invention, the broadcast control signals may be adapted to achieve the best performance for each display device.

Abstract translation: 用于有机发光二极管显示器（116）的行选择电路（118）通过移位寄存器传播选通脉冲。 该选通脉冲与系统时钟信号同步，并用于选择性地将多个广播控制信号施加到显示器（116）上的选定行像素。 线扫描电路（118）被控制以一次在线清除和自动调整显示器（116）中的像素或一次在整个图像帧处。 根据本发明的另一方面，在行被自动调整并加载新值之前，在几行间隔上执行显示器（116）中的一行像素的清除。 根据本发明的又一个方面，广播控制信号可以适合于为每个显示设备实现最佳性能。
