  • Patent number: 11830407
    Abstract: A fault-tolerant display system includes a dual thin film transistor (TFT) panel with pixel cells having two independently-controlled switching transistors; as such, primary source and gate drivers are operative to drive the display with first TFT transistors, while secondary source and gate drivers are operative to drive the display with second TFT transistors. As the display incorporates an additional TFT within the pixel cell which is driven independently, reliability is increased even at the pixel level. In this way, individual pixels of the LCD panel are driven simultaneously and independently by two pairs of source drivers and gate drivers, such that if one of the driver pairs fails due to some fault, the other driver pair can continue to drive the LCD panel without loss of information despite the failure of the first driver pair.
