Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to an anti-static structure for strengthening a display module. Background Art

[0002] The display module usually includes a cover plate, a display screen and a backlight. The display screen is usually bound with an FPC. After the FPC is bound to the display screen, the end of the FPC away from the display screen will be bent to the back of the backlight. The current smart terminals have increasingly higher requirements for the anti-static properties of the display module. Therefore, after the FPC is bent to the back of the backlight, it will be grounded to the backlight iron frame to meet the anti-static requirements of the display module.

[0003] However, the FPC in the display module of some projects is shipped unfolded, that is, there is no need to bend the FPC to the back of the backlight. In this way, it is impossible to bend the FPC to the back of the backlight and ground it to the backlight iron frame, making it impossible to meet the anti-static requirements of the display module.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] A reinforced anti-static structure for display module, referring to Figure 1 , including a display screen 10 and a backlight 20 arranged in sequence, the display screen 10 and the backlight 20 are assembled and fixed. The display screen 10 is bound with an FPC 30, the FPC 30 is in an unfolded state, one end of the FPC 30 is bound to the display screen 10, and the end of the FPC 30 away from the display screen 10 is used to connect with a client host to ensure the normal use of the display screen 10.

[0025] Reference Figure 1 Since the FPC30 of the display screen 10 of some projects needs to be rolled out for shipment, the FPC30 cannot be bent to the back of the backlight 20 for grounding connection. Therefore, a grounding leakage copper area 40 for grounding connection is provided on one side of the FPC30. The grounding leakage copper area 40 is formed by extending outward from one end of the FPC30 bound to the display screen 10. The grounding leakage copper area 40 and the FPC30 are integrally formed. The grounding leakage copper area 40 can be bent freely, and the grounding leakage copper area 40 can be bent separately to the back of the backlight 20 and grounded to the iron frame on the back of the backlight 20 to ensure the anti-static function of the display module.

[0026] Reference Figure 1 A U-shaped groove 50 is provided between the ground leakage copper area 40 and the FPC 30 for separation, and the lower end of the U-shaped groove 50 is connected to the outside, so that the ground leakage copper area 40 can be bent separately. The width of the U-shaped groove 50 is 1 mm, that is, the spacing between the ground leakage copper area 40 and the FPC 30 is 1 mm. By providing the U-shaped groove 50 to separate the ground leakage copper area 40 and the FPC 30, the ground leakage copper area 40 can be bent separately to the back side of the backlight 20 for grounding connection, and the ground leakage copper area 40 will not affect the state of the FPC 30 when bending.

[0027] Reference Figure 2 A grounding PAD41 is provided on the back of the ground leakage copper area 40. The grounding PAD41 is used to connect the ground leakage copper area 40 to the back of the backlight 20 to achieve grounding connection. When the ground leakage copper area 40 is bent to the back of the backlight 20, the grounding PAD41 on the ground leakage copper area 40 contacts the back of the backlight 20.

[0028] Reference Figure 2A conductive cloth 60 is provided on the back side of the backlight 20 at a position where the grounding PAD 41 contacts the back side of the backlight 20. The conductive cloth 60 is adhered to the back side of the backlight 20, and the conductive cloth 60 is double-sided adhesive. When the grounding copper leakage area 40 is bent to the back side of the backlight 20, the grounding PAD 41 is correspondingly attached to the conductive cloth 60, so that the grounding copper leakage area 40 is adhered to the back side of the backlight 20, and the grounding PAD 41 and the iron frame on the back side of the backlight 20 are grounded through the conductive cloth 60.

[0029] Further, refer to Figure 2 , the thickness of the conductive cloth 60 is 0.1 mm.

[0030] Further, refer to Figure 2 and Figure 3 An alignment line 70 is provided on the back side of the backlight 20 relative to the outer side of the conductive cloth 60. The alignment line 70 is used to facilitate the alignment of the ground leakage copper area 40 so that the ground PAD 41 can be accurately attached to the conductive cloth 60. The alignment line 70 is arranged in a cross shape. The two outer sides of the upper end of the conductive cloth 60 are both provided with an alignment line 70. The ground leakage copper area 40 is bent to one end of the back side of the backlight 20 to align with the two alignment lines 70, thereby determining the position of the ground PAD 41, so that the ground PAD 41 is attached to the conductive cloth 60.

[0031] Further, refer to Figure 2 A connector 80 is provided at one end of the FPC 30 away from the display screen 10 . The connector 80 is located on the back of the FPC 30 . The connector 80 is used to plug the FPC 30 into the client host to ensure the normal use of the display screen 10 .

[0032] Reference Figure 1 A reinforcing plate 90 is provided on the front side of the FPC 30 relative to the connector 80. The reinforcing plate 90 is a steel sheet and is used to strengthen the strength of the FPC 30 connector 80 so that the connector 80 will not bend when plugged into the client host.

[0033] The anti-static structure is provided with a separate grounding copper leakage area 40 when some projects require the FPC 30 to be unfolded for shipment and this affects the anti-static requirements of the display screen 10. The grounding copper leakage area 40 can be bent freely so that it can be bent to the back of the backlight 20 to achieve grounding connection without affecting the unfolding of the FPC 30, thereby meeting the anti-static requirements of the display module.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
