[0024] 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.

[0025] A blister packaging structure for protecting FPC components, referring to Figure 1 , including a packaging blister tray 10 and a display module 20 placed in the packaging blister tray 10, the display module 20 is bound with an FPC 30, and one end of the FPC 30 away from the binding to the display module 20 is located outside the display module 20, and the display module 20 and the FPC 30 are respectively fixed on the packaging blister tray 10.

[0026] Reference Figure 2 and Figure 3 The display module 20 includes a cover plate 21, a display screen 22 and a backlight 23 which are arranged in sequence. The size of the cover plate 21 is larger than the size of the display screen 22 and the backlight 23, and the periphery of the cover plate 21 is located outside the display screen 22. The FPC 30 is bound to the display screen 22, and a component area 31 is arranged on the FPC 30. The component area 31 is located on the side of the FPC 30 facing the cover plate 21, and the component area 31 is correspondingly arranged on the bottom side of the cover plate 21.

[0027] Reference Figure 1 and Figure 2 A placement platform 11 is provided on the packaging blister tray 10. The placement platform 11 is formed by being recessed downward along the upper surface of the packaging blister tray 10. The placement platform 11 is used to place the display module 20. The backlight 23 of the display module 20 is placed on the placement platform 11 with the side facing downward. A placement groove 12 is provided on the placement platform 11. The display module 20 is correspondingly placed above the placement groove 12. The components on the back of the backlight 23 can be accommodated in the placement groove 12.

[0028] Reference Figure 2 and Figure 3 The packaging blister tray 10 is provided with an avoidance groove 13 for placing the FPC 30. The avoidance groove 13 is adjacent to the placement groove 12, and the depth of the avoidance groove 13 is greater than the depth of the placement groove 12. After the display module 20 is placed on the packaging blister tray 10, the FPC 30 is correspondingly placed in the avoidance groove 13, and the avoidance groove 13 is opened along the shape of the FPC 30. Since the FPC 30 is bound to the display screen 22, and the display screen 22 and the backlight 23 have a certain thickness, the FPC 30 is a flexible circuit board, and the FPC 30 will sag and be placed in the avoidance groove 13.

[0029] Reference Figure 2 and Figure 3 When the depth of the avoidance groove 13 is not enough, that is, the depth of the avoidance groove 13 is less than the thickness of the display screen 22 and the backlight 23, the component area 31 on the FPC 30 will contact the bottom side of the cover plate 21, thereby causing friction. Therefore, the avoidance groove 13 is opened along the thickness direction of the packaging blister tray 10, and the depth of the avoidance groove 13 reaches the bottom of the packaging blister tray 10. The depth of the avoidance groove 13 is greater than the thickness of the display screen 22 plus the backlight 23, so that when the display module 20 is placed on the placement platform 11, the FPC 30 naturally droops into the placement groove 12, and the component area 31 on the FPC 30 will not contact the bottom side of the cover plate 21.

[0030] Reference Figure 4 The placement platform 11 and the avoidance groove 13 on the packaging blister tray 10 are located on the same straight line. Multiple display modules 20 are placed on the packaging blister tray 10. The placement platforms 11 are set at the positions of the packaging blister tray 10 relative to the multiple display modules 20. The packaging blister tray 10 is provided with avoidance grooves 13 at the FPC 30 positions of the multiple display modules 20. One placement platform 11 and one avoidance groove 13 form a group, and multiple groups of placement platforms 11 and avoidance grooves 13 are evenly distributed along the width direction of the packaging blister platform.

[0031] Further, refer to Figure 4 The outer periphery of the placement platform 11 is provided with positioning blocks 14 for fixing the outer shape of the cover plate 21. The positioning blocks 14 are relatively arranged at the positions of the two long side sections of the placement platform 11. The positioning blocks 14 between two adjacent placement platforms 11 play the role of separating the two placement platforms 11. The outer shape of the cover plate 21 is positioned by the positioning blocks 14, so as to fix the display module 20 on the placement platform 11.

[0032] Further, refer to Figure 4A protective film 211 is attached to the upper surface of the cover plate 21, and a protective film tearing handle 2111 extends outward from one side of the protective film 211. A receiving groove 15 is provided in the packaging blister tray 10 relative to the position of the protective film tearing handle 2111. The receiving groove 15 is connected to the placement platform 11. When the display module 20 is placed on the placement platform 11, the protective film tearing handle 2111 is correspondingly placed in the receiving groove 15.

[0033] 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.
