Embodiment Construction

[0032] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] The two rows of parallel signal ports are respectively marked as the start (start) port and the end (end) port; the pitch between each terminal of the start port and each terminal of the end port can be the same or different, in the actual layout design In most cases, the spacing of these two rows of ports is different; in addition to satisfying the parallel positional relationship between the start port and the end port, the overall distance should be a certain distance, and this distance is the space for wiring. Along the direction in which the ports are arranged, the start port and the end port may be aligned with each other, or there may be a certain offse...

Abstract

The invention discloses an odd-even alternating equivalent resistance wiring method between parallel ports. The method comprises the following steps of selecting two sets of mutually parallel ports needing to be wired for connection, and dividing index of the ports to be paired into odd indexes and even indexes; setting geometrical and physical parameters of electrical constraint for controlling a wiring process; wiring according to the set electrical constraint; adjusting resistance; and outputting a resistance report form and a resistance graph. When the signal port has mixed signals which are regularly distributed in an odd-even manner, wiring can be efficiently completed at a time, various electrical properties can be automatically met, and design efficiency of a panel layout can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of flat panel display layout design, in particular to a wiring method between parallel ports in the flat panel display layout design. Background technique [0002] There are two driving methods for liquid crystal displays, passive matrix and active matrix. At present, a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display, TFT-LCD), as a representative of the active matrix driving method, has become a mainstream product in LCD applications. The TFT-LCD driving circuit includes a power supply circuit, a timing control circuit, a grayscale circuit, a data driving circuit, a scanning driving circuit and a system interface. [0003] In the layout design stage of the flat panel display, the layout and wiring of the driving circuit is an important work. When designing wiring, in addition to meeting the requirements of minimum line width and minimum line spacing, there are also...
