Abstract: The present disclosure proposes an in-cell touch display panel and a gate driver on array (GOA) circuit. A pre-charging circuit is arranged on an nth stage GOA unit circuit of the GOA circuit and the in-cell touch display panel. A first node controlling signal on a first node of an (n+2)th stage GOA unit circuit is pre-charged, reducing a risk of failure of stage-by-stage signal transmitting arising from poor holding voltage of the GOA unit circuit during the signal suspending and improving reliability of the GOA circuit.

Abstract: The present invention provides a LTPS TFT substrate and a manufacturing method thereof. The LIPS TFT substrate of the present invention includes a metal layer formed on a channel zone so that the metal layer, a source electrode, and a drain electrode can be used as a mask to form LDD zones in a poly-silicon layer in order to save the mask needed for separately forming the LDD zones; further, due to the addition of the metal layer that is connected to the channel zone of the poly-silicon layer, the electrical resistance of the channel zone can be effectively reduced to increase a TFT on-state current. The LTPS TFT substrate manufacturing method of the present invention forms a metal layer on a channel zone at the same time of forming a source electrode and a drain electrode and uses the metal layer, the source electrode, and the drain electrode as a mask to form LDD zones in a poly-silicon layer so as to save the mask needed for separately forming the LDD zones thereby reducing the manufacturing cost and increasing throughput.

Abstract: The present invention provides a GOA circuit of reducing feed-through voltage. An eleventh thin film transistor (T11) and a first capacitor (R1) coupled to the eleventh thin film transistor (T11) in series are added in a pull-down output unit (400). In the output process of the GOA circuit, the eleventh thin film transistor (T11) is activated with the added output control signal (CKF). With the voltage division function of the first resistor (R1), one more falling edge is generated to the waveform outputted by the output end (G(n)). Namely, the waveform outputted by the output end (G(n)) comprises two falling edges. Thereby, the voltage difference before and after the gate of the TFT in the pixel can be decreased to reduce the feed-through voltage and raise the display uniformity of the liquid crystal panel.
