Referring to FIG. 3, which is a schematic diagram of arrangement of a pixel structure of an embodiment of an active-matrix organic light-emitting diode (AMOLED) display panel according to the present disclosure.

The AMOLED display panel of the present embodiment includes a plurality of first pixel units 10 and a plurality of second pixel units 20. The first pixel units 10 and the second pixel units 20 are alternately disposed along a horizontal direction and along a vertical direction to form a pixel structure arranged in a matrix manner.

Compared with the prior art in which two sub-pixels, namely, a red sub-pixel and a green sub-pixel in a pixel 1 (as shown in FIGS. 2 and 6) are arranged along a direction that a gate line (Scan) extends, such that each of the red and green sub-pixels requires one of data lines Data, and shares the gate line (Scan), additionally, the sub-pixels are longitudinally arranged as a whole. The AMOLED display panel of the present embodiment is achieved by the first sub-pixel 11 and the second sub-pixel 12 in the first pixel unit a share one of the data lines Data, and by the first sub-pixel 11 and the third sub-pixel 13 in the second pixel unit b share one of the data lines Data, such that a quantity of the data lines Data is reduced, thereby reducing a quantity of fan-out wires, and reducing a space required for wiring in a fan-out area, so as to reduce a size of a lower bezel.

Thin film transistor liquid crystal displays (TFT-LCD) are the main variety of current flat-panel displays. The main driving principle of a TFT-LCD is shown in

SUMMARY OF THE INVENTION

Preferably, the first start signal comprises an initial pulse vertical signal, the initial pulse vertical signal being used as a start-up signal of each refreshed screen of the odd stage gate COF.

The present application arranges the G-COF in the single side drive structure on two sides of the display panel, to increase the space of the wiring of the fan-out area of the fan-out area on the gate side. Please refer to FIG. 2 and FIG. 3. FIG. 2 illustrates a diagram of a structure of a gate driver panel according to an embodiment of the present invention, and FIG. 3 illustrates a diagram of the detailed structure in FIG. 2. As shown in FIG. 2, a display panel 2 has a display area 20, a plurality of odd stage scan lines and even stage scan lines (like an odd stage scan line GL1 and an even stage scan line GL2), arranged sequentially in the display area 20, and non-display area 21 located at two sides of the display area 20. The panel 2 includes a plurality of odd stage gate COFs 210, disposed on a first side 201 of the non-display area 21, wherein each odd stage gate COF has a plurality of odd stage scan output channels Ch_O corresponding to each of the odd stage scan lines respectively; and a plurality of even stage gate COFs 210′, disposed on a second side 202 opposite the first side 201 on the non-display area 21, wherein each even stage gate COF 210′ has a plurality of even stage scan output channels Ch_E corresponding to each of the even stage scan lines respectively.

As shown in FIG. 3, a first odd stage gate COF COF 210_1 of the plurality of odd stage gate COFs 210 sequentially drives each of the odd stage scan output channels Ch_O according to a first start signal STV, and in the first odd stage gate COF 210_1, the first odd stage scan output channel Ch_O_1 outputs a scan drive signal S_Gate1 to a first even stage gate COF 210_1′ of the plurality of even stage gate COFs 210′ through a first odd stage scan line GL1, and uses the scan drive signal S_Gate1 as a second start signal S_ini of the first even stage gate COF 210_1′, to sequentially drive each of the even stage scan output channels Ch_E.

Preferably, the odd stage gate COFs 210 of the plurality of odd stage gate COFs other than the first odd stage gate COF 210_1 drive each odd stage scan output channel Ch_O correspondingly according to another scan drive signal STV′.
