Abstract

The invention relates to the technical field of display screens, in particular to a flexible circuit board, a manufacturing method of the flexible circuit board, a display screen and electronic equipment. The main board comprises a base material layer and a first conductive layer arranged on one side of the base material layer, and a first insulating layer is arranged on the face, away from the base material layer, of the first conductive layer. The bridging plate comprises a second conductive layer; the blind hole is formed between the first conductive layer and the second conductive layer, the conductive element is arranged on the side wall of the blind hole to achieve electrical connection, and compared with an existing four-conductive-layer design, the flexible circuit board has the advantage that the thickness of the flexible circuit board is greatly reduced. The invention further provides a method for manufacturing the flexible circuit board, a display screen with the flexible circuit board and electronic equipment with the flexible circuit board.

Description

【Technical field】 [0001] The present invention relates to the technical field of display screens, in particular to a flexible circuit board and a manufacturing method thereof, a display screen and an electronic device. 【Background technique】 [0002] AMOLED (Active-matrix organic light-emitting diode, active matrix organic light-emitting diode or active matrix organic light-emitting diode), is a display technology, mainly used in smartphones, and used in AMOLED FMLOC products The flexible printed circuit (FPC) has interference phenomenon caused by the intersection of the touch signal line and the MIPI signal line, which leads to the appearance of random touch points on the product. At present, in order to avoid the interference caused by the intersection of the Touch signal line and the MIPI signal line on the flexible circuit board, some products of AMOLED products adopt the design of 4-layer copper foil layer, so that the MIPI signal and the Touch signal are completely sep...
