Description

Technical Field

[0001] This utility model relates to the field of display module technology, and in particular to a product structure for improving edge breakage of OLED screens. Background Technology

[0002] Wearable OLED displays for wearable electronic devices typically include components such as display glass, FPC, driver IC, and protective foam. Organic materials are vapor-deposited inside the OLED display glass. To prevent the organic materials from reacting with air, a curing layer (frit layer) is set around the perimeter between the upper and lower glass layers. This curing layer is very brittle after curing and is easily damaged in the event of drops or impacts, resulting in damage to the display and rendering it unusable. Experiments and tests have shown that when the FPC is bent, the connectors located at the edge of the screen (display glass) are prone to cracking of the curing layer at the edge of the screen when dropped or impacted.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a product structure that improves the edge breakage of OLED screens, thereby reducing the problem of cracking and damage to the curing layer (Frit layer) of the display screen.

[0005] The technical solution of this utility model is as follows: This utility model provides a product structure for improving the edge breakage of an OLED screen, including: an OLED display screen, the OLED display screen including display glass and a module FPC, the display glass and the module FPC being bonded together, a connector being provided on the connection end of the module FPC, a connector steel plate being provided on the back of the connector, a buffer foam being provided on one side of the module FPC on the connector steel plate, and the buffer foam being positioned on the side of the module FPC near the edge of the display glass after bending, the corresponding edge of the buffer foam being flush with the edge of the module FPC, the width of the buffer foam being greater than or equal to one-quarter of the width of the module FPC at its position, the distance between the edge of the buffer foam and the corresponding connector steel plate being 3mm-5mm, and the top surface of the buffer foam exceeding the top surface of the connector steel plate by 0.15mm.

[0006] Furthermore, the cushioning foam has a cushioning thickness of 0.25 mm.

[0007] Furthermore, after compression, the top surface of the cushioning foam is flush with the steel sheet of the connector.

[0008] Furthermore, the length of the cushioning foam is 8mm-15mm.

[0009] Furthermore, the cushioning foam has conductive properties, and copper is exposed on the module FPC at the location where the cushioning foam is attached.

[0010] The beneficial effects of this utility model by adopting the above solution are as follows: by setting buffer foam at the position of the connector steel plate, the connector steel plate can be effectively prevented from colliding with the edge of the display glass and causing the curing layer (Frit layer) to crack, thereby improving the reliability and quality of the product.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please refer to the following: Figures 1 to 4 In this embodiment, the present invention provides a product structure for improving the edge breakage of an OLED screen, including: an OLED display screen, the OLED display screen including a display glass 1 and a module FPC 2, the display glass 1 and the module FPC 2 being bonded together, a connector 3 being provided on the connection end of the module FPC 2, a connector steel sheet being provided on the back of the connector 3, a buffer foam 4 being provided on one side of the module FPC 2 on the connector steel sheet, and the buffer foam 4 being positioned on the side of the module FPC 2 after bending close to the edge of the display glass 1, the corresponding edge of the buffer foam 4 being flush with the edge of the module FPC 2, the width of the buffer foam 4 being one-third of the width of the module FPC 2 at its setting position, the distance between the edge of the buffer foam 4 and the corresponding connector steel sheet being 3mm-5mm, the length being 10mm, and the height of the top surface of the buffer foam 4 exceeding the top surface of the connector steel sheet being 0.15mm, that is, the thickness of the buffer foam 4 being 0.15mm thicker than the thickness of the connector steel sheet.

[0017] Furthermore, the cushioning foam 4 has a cushioning thickness of 0.25mm. After compression, the top surface of the cushioning foam 4 is flush with the connector steel plate. This ensures that after compression, the top surface does not extend beyond the top surface of the connector steel plate, thus avoiding interference with the positive electrode assembly.

[0018] Furthermore, the buffer foam 4 has conductive properties, and the copper exposed at the attachment position of the buffer foam 4 on the module FPC 2 helps to enhance the antistatic performance of the module, allowing static electricity to be discharged through the exposed copper of the module FPC 2, the buffer foam 4, and the back of the display screen.

[0019] In summary, the beneficial effects of this solution are as follows: by placing buffer foam at the connector steel plate position, it is possible to effectively prevent the connector steel plate from colliding with the edge of the display glass, which would cause the cured layer (Frit layer) to crack, thus improving the reliability and quality of the product.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
