Abstract

The invention provides a flexible circuit board and a manufacturing method thereof, a display device and a mobile terminal. The flexible circuit board comprises a body and a bending portion arranged on one side of the body. The bending portion is bent along a bending line relative to the body. The bending portion comprises a flexible substrate and a conductive layer. The conductive layer is arranged on the flexible substrate, a first stress groove is arranged in one side surface, facing the flexible substrate, of the conductive layer, a second stress groove is arranged in the other side surface of the conductive layer, and the first stress groove and the second stress groove extend along a direction parallel to a bending line. By using the display device and the mobile terminal of the flexible circuit board, an occupied width of the flexible circuit board can be reduced by bending the bending portion of the flexible circuit board so that frame widths of the display device and the mobile terminal are reduced, and a narrow frame design is realized.

Description

technical field [0001] The present disclosure relates to an electronic device, in particular to a flexible circuit board, a manufacturing method thereof, a display device, and a mobile terminal. Background technique [0002] At present, due to the rapid development of display technology, OLED organic light emitting diode (Organic Light Emitting Diode, OLED) display screen has a large viewing angle, saves power, fast response, no backlight, wide color gamut, high contrast, and overall structure The advantages of thinness and lightness make OLED display screens more and more widely used. [0003] The front side of an OLED display panel is generally divided into an active display area and a non-display area. The effective display area corresponds to the visible area, and the non-display area corresponds to the frame area. In a traditional OLED display panel, since the touch sensing circuit is disposed on the cover plate, it is necessary to electrically connect the touch sensi...
