摘要： The present invention teaches a GOA circuit driving method and a GOA circuit driving device. Through the configuration of a buffer capacitor electrically connected to the level shift IC, the level shift IC connects to the buffer capacitor and switches to the transition level during shifting the target clock signals from high to low level or from low to high level. Through the buffer capacitor, the present invention is able to keep the transition level always equal to one half of the sum of the low voltage and the high voltage, thereby maximizing reduction of power consumption and feedthrough effect of the GOA circuit.

摘要： A liquid crystal panel including an array substrate and a color filter substrate which are disposed opposite and multiple fan-out lines and a color resist layer stacked along a direction from the array substrate toward the color filter substrate. The color film substrate is provided with a common electrode layer. A color resist layer and a columnar spacer are mutually abutted to ensure a distance between the array substrate and the color filter. The color resist layer includes a first plane facing the columnar spacer, and the common electrode line or the common electrode layer surrounds the color resist layer and exposes the first plane. When the liquid crystal panel is subjected to a larger external force such that deformation or displacement occurs between the columnar spacer and the color resist layer, the common electrode line and the common electrode layer are not conductive to form a short circuit.

摘要： In a driving system of a display device, wires are arranged on a first connection unit, a second connection unit and a third connection unit and the traces are arranged on a first circuit board, a second circuit board and a third circuit board accordingly. The electrical path is established on the aforesaid circuit boards and the aforesaid connection units. One end of the electrical path is connected to the power supply voltage, and the other end is connected to the input end of a timing controller. When all the connection units are connected, the power supply voltage is inputted to the timing controller via the path, and the timing controller outputs the power supply control signal for controlling the display device to power on. When the connection units are poorly connected, the timing controller outputs a power supply stopping control signal to stop powering the display device.
