Embodiment Construction

[0116] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0117] When an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may be present. also exist. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may mean that other elements exist between two elements.

[0118] Additionally, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe one element's relationship to another element as shown in the figures. It will be understood that rela...

Abstract

The invention discloses a flexible circuit board which comprises a flexible base material and a detection loop arranged on the flexible base material. The flexible base material is provided with a first side edge area and a central area connected with the first side edge area. The detection loop is provided with a first detection part and a second detection part, the first detection part comprises a wire and is arranged in the first side edge area, and the second detection part comprises two wires and is at least partially located in the central area. One end of the second detection part is connected with the first detection part.

Description

technical field [0001] This disclosure relates to a flexible circuit board and a display device using the same, especially to the wiring of the flexible circuit board. Background technique [0002] The flexible circuit board can simplify the packaging process, reduce the cost and reduce the packaging volume, etc., so it has become a very important technology in the current display device. In addition, the overall market share of curved display devices continues to increase year by year. In order to meet the stress relief of the panel when it is bent, the flexible circuit board usually introduces an inwardly concave shape design. [0003] The flexible circuit board can be punched to form a specific shape. If the cutting position deviates, not only will the appearance fail to meet expectations, it may even cause missed or wrong cuts, which will affect the reliability of the process. Contents of the invention [0004] According to some embodiments of the present disclosure,...
