no. 1 approach

[0044] figure 1 An exploded view of the display device 100 according to the first embodiment of the present invention is shown. figure 2 draw figure 1 A partial cross-sectional view of the assembled part M1 of the display device 100 . Such as figure 1 and figure 2 , the display device 100 includes a display panel 110 , a circuit substrate 120 , a grounding pad 130 and a conductive shell 140 . The conductive shell 140 has a protruding portion 150 . The ground pad 130 is located on the circuit substrate 120 . The circuit substrate 120 is electrically connected to the display panel 110 . At least one cutting slit 131 is formed on the circuit substrate 120 and the ground pad 130 at the same time. The cutting slit 131 runs through the ground pad 130 and the circuit substrate 120 at the same time, and the cutting slit 131 defines a plurality of contact portions 132 on the ground pad 130 .

[0045] In this way, when the conductive shell 140 is assembled on the circuit board ...

no. 2 approach

[0053] Figure 4A A front view of the ground pad 230 according to the second embodiment of the present invention is shown. Figure 4B A front view of the protruding portion 250 according to the second embodiment of the present invention is shown. Such as Figure 4A and Figure 4B As shown, the display device of the second embodiment is substantially the same as the display device of the first embodiment, and the difference is that the pattern of the cutting slit 231 is in the shape of "one", that is, the number of the cutting slit 231 is only one. indivual. The cutting slit 231 is linearly formed on the ground pad 230 and the circuit substrate 120 , so that the number of contact portions 232 of the ground pad 230 is two (2*1). The number of contact surfaces 251 of the protruding portion 250 is two (2*1). In the second embodiment, the extreme protrusion 252 is a line edge, which is the intersection of the two contact surfaces 251 of the protrusion 250 . In this way, when ...

no. 3 approach

[0056] Figure 5A A front view of the ground pad 330 according to the third embodiment of the present invention is shown. Figure 5B A front view of the protruding portion 350 according to the third embodiment of the present invention is shown. Figure 5C draw Figure 5B side view. Such as Figure 5A and Figure 5B As shown, the display device of the third embodiment is substantially the same as the display device of the first embodiment, the difference is that the pattern of the cutting slit 331 is "X", that is, the number of the cutting slit 331 is 2, The number of contact portions 332 of the ground pad 330 is four (2*2). The protrusion 350 is a pyramid, for example, a four-sided pyramid, however, the present invention is not limited to the number of corners. The number of contact surfaces 351 of the protruding portion 350 is four (2*2). In the third embodiment, the extremely convex portion 352 is a pointed apex. The vertex is the intersection point of the four conta...

Abstract

The invention discloses a display device which comprises a display panel, a circuit substrate, a grounding pad and a conductive shell. The circuit substrate is in electrical connection with the display panel. The grounding pad is located on the circuit substrate. Slicing seams penetrate through the grounding pad and the circuit substrate. The slicing seams are provided with a plurality of contact parts on the grounding pad. The conductive shell is provided with a protruding portion which presses and bends the contact portions, so that the bent contact portions are attached to the protruding portion.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display device with an electrostatic protection mechanism. Background technique [0002] Electromagnetic Interference (EMI) and Electrostatic Discharge (ESD) often damage components in the display device, and even cause the display device to fail to operate normally. For this reason, a protection mechanism for reducing electrostatic discharge is provided in the display device. For example, one of the protection mechanisms will allow the bottom case to directly touch the ground contact on the flexible printed circuit board of the display panel when the display panel and the bottom case of the display device are assembled, so as to achieve the contact between the bottom case and the ground contact. Electrical conduction. [0003] However, when the display panel is assembled to the bottom case, if the rebound force of the ground pad of the flexible printed circuit board is too lar...
