Problems solved by technology

Nevertheless, the length of the flexible circuit board will still increase with the increase in the size of the display panel, especially for a display panel of more than 10 o'clock, the length of a single flexible circuit board is too long, and the precision requirement is quite high, and The manufacturing and alignment processes of flexible circuit boards are not easy to control, so the price of flexible circuit boards is too expensive, and the loss of pass rate is very high, which is not conducive to the development and application of portable panels

Abstract

This invention provides a soft CB connection structure including a base plate, multiple driving circuits set on the base plate, at least an open-front set at the back of the base plate, a connector in the open-front and multiple soft circuit boards connecting the driving circuits and the connector.

Description

technical field [0001] The invention relates to a connection structure of a flexible circuit board, in particular to a connection structure of a flexible circuit board of a portable panel. Background technique [0002] Flexible circuit board is a kind of flexible circuit board. Because it can greatly reduce the space occupied by the circuit board, it has been widely used in various electronic products, especially portable and thin Electronic products, including mobile phones, digital cameras, portable VCD / DVD and car monitors, etc. Flexible circuit boards are mostly used as a connector in practical applications, connected between different circuit components, such as between the display panel and the signal control circuit, to transmit image signals to the display panel, and control the display panel The screen above is displayed. [0003] refer to figure 1 , figure 1 It is a schematic diagram of a known flexible printed circuit board connection structure. Such as figu...
