Embodiment Construction
[0049] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.
[0050] In the drawings, certain regions are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when an element such as a region or a substrate is referred to as being "on" or "connected (or called coupled)" or "electrically connected" to another element, it may be directly on the other element. On or with another element (or referred to as coupling) or electrically connected, or intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there...

Description
technical field [0001] The present invention relates to a display, in particular to a gate drive circuit disposed on a gate drive circuit array substrate (Gate OnArray, GOA) and operated in a single-side drive mode and an operation method thereof. Background technique [0002] Generally speaking, when the gate drive circuit 1 disposed on the gate drive circuit array substrate (GOA) operates in a single-side drive mode, as figure 1 As shown, the traditional approach is to input the scan line drive signal (such as figure 1 The second driving signal SD2) in the middle is intercepted, and the scanning line driving signal input from the other side (for example figure 1 in the first drive signal SD1) to drive. [0003] However, the above-mentioned traditional one-side driving method can easily cause bright and dark lines in the horizontal direction to appear in the picture displayed on the display panel PL, seriously affecting the quality of the display picture, and needs to be ...
