    Abstract: A display has an array of pixels controlled by display driver circuitry. Gate driver circuitry supplies gate line signals to rows of the pixels. The pixels may be liquid crystal display pixels. Each pixel may have a common electrode voltage terminal. The display may have a transparent conductive film that forms a common electrode voltage layer that overlaps that array and that is shorted to the common electrode voltage terminals of the pixels. Metal common electrode voltage lines may run across the transparent conductive film to reduce resistance. Metal common electrode voltage paths that are coupled to the metal common electrode voltage lines may run along the left and right edge of the display. Common electrode voltage compensation circuits may receive feedback from the metal common electrode voltage paths. There may be two or more common electrode voltage compensation circuits for both the left and right edges of the display.

    Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The first (upper) stage may be a high resolution display panel that is operated at a first refresh rate while the second (lower) stage is a low resolution display panel that is operated at a second refresh rate that is greater than the first refresh rate. In particular, the second stage may be configured to provide localized dimming that is synchronized to one or more moving objects in the video frames to be displayed to help reduce the perceived motion blur. The localized dimming may be provided via insertion of a black image portion that only overlaps with the moving objects, a blanking row that tracks the moving objects, a black frame, etc.

    Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The pixel pitch of the second stage may be greater than the pixel pitch of the first stage to ease alignment tolerances and reduce image processing complexity. The first stage may be provided with straight black masking strips, whereas the second stage may be provided with angled zigzagging black masking strips. The angle of the zigzagging black masking strips and the ratio of the pixel pitch of the second stage to that of the first stage may be selected to maximize optical transmittance while minimizing Moire effects.

    Abstract translation: 显示器可以具有第一级，例如彩色液晶显示级和第二级，例如单色液晶显示级，其串联耦合，使得来自背光的光通过两级。 第二级的像素间距可以大于第一级的像素间距，以减轻对准公差并降低图像处理的复杂性。 第一阶段可以设置有直黑色掩蔽条，而第二阶段可以设置有成角度的锯齿形黑色掩蔽条。 可以选择锯齿状黑色掩模条的角度和第二级的像素间距与第一级的像素间距的比率以使光线透射率最大化，同时最小化莫尔效应。
