Abstract: An active matrix device includes a substrate, scan lines, data lines, pixels, electrostatic discharge ring, a circuit board and a electrostatic protection circuit. The scan lines and data lines are disposed on the substrate, in which the data lines cross the scan lines. The pixels are electrically coupled to the data lines and the scan lines. The electrostatic discharge ring is disposed on the substrate. The electrostatic protection circuit is coupled between the electrostatic discharge ring and the circuit board, in which the electrostatic protection circuit prevents the electrostatic current on the circuit board from entering the substrate.
Abstract: An E-ink display panel including a substrate, display pixels, dummy pixels, a display medium and a common electrode is provided. The display pixels are disposed on the substrate and arranged in a matrix for defining a display region. The dummy pixels are disposed on the substrate and adjacent to the display pixels. The display medium is disposed over the display pixels and the dummy pixels. The common electrode is disposed on the display medium. The display medium above the display pixels is driven by the bias voltage between the display pixel and the common electrode such that an image is displayed by the display medium, and display state of the display medium above the dummy pixels is not affected by the bias voltage between the dummy pixel and the common electrode. The dummy pixels are adapted for preventing the display pixels from being damaged directly due to an ESD.
Abstract: An active matrix device including an active region and an ESD protection circuit is provided. The active region includes scan lines and data lines. The ESD protection circuit includes a first power line, a second power line, a first diode and a second diode. The first diode is electrically connected between the scan line/data line and the first power line, and the second diode is electrically connected between the second power line and the scan line/data line. When a positive or negative ESD voltage is applied to the scan lines or the data lines, the ESD current is conducted to the first power line or the second power line through the first diodes or the second diodes, so as to protect the devices and circuits of the active matrix device from being damaged by the ESD zap.
