Abstract: Disclosed is an array substrate and a method for manufacturing the same, a liquid crystal display panel, wherein the array substrate includes: a first material layer and a first conductive layer formed on the first material layer, wherein a region of the first material layer that is not covered by the first conductive layer is etched away in whole or in part along a thickness direction. The array substrate can enable an effective gap of a liquid crystal cell to be increased, thereby improving the transmittance of the panel, and meanwhile can ensure that the response time of the liquid crystal display panel containing the array substrate will not be increased.

Abstract: A GOA electric circuit introduces a resistor and a timing signal, which are used to replace a second capacitor in the existing skills. One terminal of the resistor is connected to a constant high voltage level and the other terminal thereof is connected to a gate electrode of a ninth thin-film transistor. A source electrode of the ninth thin-film transistor is electrically connected to the timing signal. In the stage maintaining the output terminal at low voltage level, the voltage level of the second node can be changed between high and low voltage levels as the timing signal is changed, and the voltage level of the second node is pulled down in a specific frequency. This effectively prevents the second node from being at high voltage level for a long time and avoids the problem of threshold voltage shifting, and therefore improves the stability of GOA electric circuit.

Abstract: A gate driving circuit disposed on an array substrate and an LCD using the same are described. The gate driving circuit on the array substrate comprises a plurality of sequentially connected gate driving units. The gate driving circuit unit comprises an input module, a reset module, a latch module and a signal processing module. The signal processing module receives the current inverse stage-transmitting signal XQ(N), the low voltage signal, a second clock signal and a third clock signal to control on/off statuses of two transistors by the current stage-transmitting signal Q(N) so that the two transistors forms Nth gate signal G(N) and gate signal (N+1)th based on the second clock signal and the third clock signal. The present invention utilizes less clock signals and transistors, which is favorable to the narrower LCD's frame design and solves the problem of manufacturing process restriction of the LCD panel.
