Embodiment 1

[0023] image 3 It is a schematic structural diagram of an alignment mark provided by Embodiment 1 of the present invention. Such as image 3 As shown, the alignment mark 102 is set on the binding area 101, and the alignment mark 102 is used to locate the parts to be bound during the binding process, and the alignment mark 102 is set on the parts to be bound The first gold finger 103 on the top constitutes. A plurality of second golden fingers 104 spaced apart from each other are also arranged on the binding area 101 . Optionally, there are two alignment marks 102 in one binding area 102, wherein one alignment mark 102 is set at one end of the binding area 101, and the other alignment mark 102 is set at the end of the binding area 101. The other end of the binding area 101.

[0024] In practical applications, the components to be bound include flexible circuit boards or printed circuit boards. Gold Finger (Gold Finger) is the interface between the circuit of the printed c...

Embodiment 2

[0028] Figure 5 It is a schematic structural diagram of a circuit board provided by Embodiment 2 of the present invention. see image 3 and Figure 5 , the circuit board includes a substrate 105, and the substrate 105 is provided with a binding area 101, and the binding area 101 is provided with the alignment mark 102 provided in the first embodiment. The alignment mark 102 is used for positioning the components to be bound during the binding process, and the alignment mark 102 is composed of a first golden finger 103 arranged on the components to be bound. A plurality of second golden fingers 104 spaced apart from each other are also arranged on the binding area 101 . Optionally, there are two alignment marks 102 in one binding area 102, wherein one alignment mark 102 is set at one end of the binding area 101, and the other alignment mark 102 is set at the end of the binding area 101. The other end of the binding area 101.

Abstract

The invention discloses a counterpoint label, a circuit board and a display device. The counterpoint label is used for positioning a component to be bound in the binding process; the counterpoint label consists of a first golden finger arranged on the component to be bound. The counterpoint label disclosed by the invention is arranged inside a binding area, so that effective areas of the circuit board are not additionally occupied, relatively more elements and components can be placed on the circuit board, the utilization rate of the circuit board can be increased, and the requirement of narrowing the side of the circuit board can be met.

Description

technical field [0001] The invention relates to the technical field of integrated electric boards, in particular to an alignment mark, a circuit board and a display device. Background technique [0002] figure 1 It is a structural schematic diagram of an alignment mark in the prior art. Such as figure 1 As shown, the alignment mark 102 is set on both sides of the binding area 101 . figure 2 It is a structural schematic diagram of another alignment mark in the prior art. Such as figure 2 As shown, the alignment mark 102 is set under the binding area 101 . The above-mentioned alignment mark is set on the bottom or both sides of the binding area, so that other components can not be set in the area where the alignment mark is set, which will waste a part of the circuit board area, thereby reducing the utilization rate of the circuit board, and making the circuit The volume of the board is too large, which cannot meet the requirements of narrowing the circuit board. Con...
