Embodiment Construction

[0033] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

[0034] see Figure 4 As shown, an embodiment of the present invention provides a GOA circuit 30 , including a first subunit 31 , a second subunit 32 and a third su...

Abstract

The embodiment of the invention discloses a GOA circuit and a display panel thereof. The GOA circuit includes at least one first subunit, distributed in parallel on both sides of the GOA circuit; at least one second subunit, distributed in the middle of the GOA circuit parallel to the first subunit; the first subunit The width is greater than the width of the second subunit. The display panel includes the above-mentioned GOA circuit and a panel frame glue circuit, the panel frame glue circuit is arranged in parallel above the GOA circuit, and the panel frame glue circuit and the GOA circuit are arranged correspondingly. The invention provides a GOA circuit, which reduces its width by reducing the opening ratio of the middle subunit of the overall circuit of the GOA circuit, which can realize the narrow frame design of the panel while satisfying the problems of curing the frame glue to avoid liquid crystal pollution and puncture. The expansion of the narrow bezel market promotes the progress of narrow bezel panels.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a GOA circuit under a sealant and a display panel thereof. Background technique [0002] At present, the curing of the seal requires ultraviolet (UV) light irradiation. In order to ensure the complete curing of the seal, the areas that the seal may cover are designed as follows: figure 1 The frame glue circuit 10 shown in the figure ensures that the light transmittance is about 50%. figure 1 By figure 2 The frame plastic line sub-unit 11 is composed of graphics. However, considering that the curing of the frame glue is mainly to avoid liquid crystal (Liquid Crystal, LC) pollution and puncture, etc., it is sufficient to ensure the complete curing of the edge of the frame glue without fully curing the frame glue as a whole. [0003] Array substrate line drive (GOA, Gate Driver On Array or Gate On Array) circuit is to use the existing thin film transistor display (TFT-LCD) arra...
