摘要： An organic light emitting diode (OLED) display includes at least one shield electrode between a cathode layer and an OLED drive circuit. The OLED drive circuit has at least one thin-film transistor (TFT), and the shield electrode is disposed to correspond to the thin-film transistor and closer to the cathode layer, covering an entire region between the source and drain of the thin-film transistor. The shield electrode is either grounded or tied to the gate of the thin-film transistor, to thereby minimize parasitic capacitances in the pixels of the display to enhance the display performance. The presented architecture enables high density drive circuit integration in amorphous silicon or other technologies, yet preserving a high display aperture ratio.

摘要： A system and method for operating a display at a constant luminance even as some of the pixels in the display are degraded over time. Each pixel in the display is configured to emit light when a voltage is supplied to the pixel's driving circuit, which causes a current to flow through a light emitting element. Degraded pixels are compensated by supplying their respective driving circuits with greater voltages. The display data is scaled by a compression factor less than one to reserve some voltage levels for compensating degraded pixels. As pixels become more degraded, and require additional compensation, the compression factor is decreased to reserve additional voltage levels for use in compensation.
摘要翻译：一种用于以恒定亮度操作显示器的系统和方法，即使在显示器中的一些像素随时间而降低。显示器中的每个像素被配置为当向像素的驱动电路提供电压时发光，这导致电流流过发光元件。通过向各自的驱动电路提供更大的电压来补偿退化的像素。显示数据按照小于1的压缩因子进行缩放，以保留用于补偿退化像素的一些电压电平。当像素变得更加恶化并且需要额外的补偿时，压缩因子被减小以保留用于补偿的附加电压电平。
