Problems solved by technology

For example, in the process of picking and placing the semi-finished panel, because points P1 and P2 bear the weight of the entire printed circuit board 92 or are accidentally pulled by people, the flexible circuit board 91 is prone to peeling (peeling), resulting in flexible circuit board 91. 94 corners of the circuit break, and eventually lead to abnormal phenomena such as vertical lines

Embodiment Construction

[0028] In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

[0029] In the present invention, the same or corresponding components are represented by the same reference numerals regardless of the figure number, and throug...

Abstract

The invention provides a flexible circuit board and a display device. The flexible circuit board comprises a substrate and a circuit element. The substrate has a functional area and at least two redundant areas on the two sides of the functional area respectively. The circuit element is arranged in the functional area for connecting signal lines and transmitting signals. The circuit element comprises a signal input end and a signal output end. The display device comprises a display panel, a circuit board and the flexible circuit board. The circuit board is electrically connected with the inputend of the functional area, and the display panel is electrically connected with the output end of the functional area. By widening one side of the input end of the flexible circuit board, the problem that the peeling of the two sides of the input end under force directly leads to the circuit breaking of the corner lines on the flexible circuit board is avoided. Furthermore, the crack propagationin the redundant areas can be blocked by arranging through holes, so that the integrity of the corner lines of the flexible circuit board can be protected, and normal picture display of open cells can be ensured.

Description

technical field [0001] The invention relates to the display field, in particular to a flexible circuit board and a display device. Background technique [0002] Such as figure 1 As shown, in the existing panel semi-finished product (open cell) architecture, the input end of the flexible circuit board 91 (COF) is bound to the printed circuit board 92 (PCB), and the output end of the flexible circuit board 91 is bound to the panel 93 , the printed circuit board 92 transmits signals to the panel 93 via the flexible circuit board 91 for display. Today, this architecture is so common that almost all high-definition panels use it. [0003] Such as figure 1 , figure 2 As shown, there is a very serious defect in this panel semi-finished structure. For example, in the process of picking and placing the semi-finished panel, because points P1 and P2 bear the weight of the entire printed circuit board 92 or are accidentally pulled by people, the flexible circuit board 91 is prone ...
