[0003] The current GDL circuit (array substrate line drive, Gate Driver Less) is applied to ultra-high-definition large-size products, but due to changes in customer consumption needs, factory technical requirements, and progress in process capabilities, the screen resolution is increased, the frame width is reduced, and the The screen-to-body ratio of the screen is a trend. For a screen of the same size, increasing the resolution means that the size of each pixel becomes smaller; this requires the GDL circuit to ensure performance and safety in a limited space, and to play its due role. Some functions; but due to design reasons, such as timing control and the control connection of multiple signals to transistors, the number of transistors in the GDL circuit is as many as dozens, resulting in the GDL circuit layout design not meeting the frame specifications. Requirements; therefore, it is necessary to re-modify the GDL circuit design to reduce the space occupied by the GDL circuit as much as possible under the condition of satisfying the driving capability, so as to meet the requirements of narrow frame and high resolution
