Abstract

The invention discloses a separate type control printed circuit board using for display plate, including the main circuit plate and the subsidiary circuit plate. The main circuit plate stations a control circuit for outputting control signal, and the subsidiary circuit utilizes flexible circuit plate, flexible drop-out plate line and linker to connect with main circuit plate. The subsidiary circuit utilizes TCP of tape coiling type or flexible circuit plate to connect with display plate, and the line on the subsidiary circuit plate can transport or magnify the control signal of main circuit plate to display plate. The invention only need changing the main circuit plateí»s design to achieve modularization, the assemble package is easy and can saving time, and it does not need designing differ implement to match differ circuit plate to bear the weight.

Description

technical field [0001] The present invention relates to a separate control printed circuit board, and in particular to a separate control printed circuit board applicable to a display panel. Background technique [0002] The control printed circuit board (Printed Circuit Board, PCB) is an indispensable basic component of all information electronic products. It acts as the main carrier when installing and plugging various electronic components. A kind of electronic components, by controlling the circuit design of the printed circuit board, the purpose of relay transmission is achieved, so that the functions of various components can be brought into play. [0003] The control printed circuit board can be electrically connected to other substrates or through flexible circuit boards (Flexible Printing Circuit board, FPC), tape carrier packages (Tape Carrier Package, TCP) or flexible cables (FFC). interface. Taking the liquid crystal display module as an example, the source con...
