Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and more specifically to a liquid crystal display screen that complies with electrostatic testing. Background Art

[0002] The industry now has higher and higher requirements for anti-static of AMOLED smart watch projects. Some customers have required the ability to resist external static electricity to reach 15KV to 18KV. Therefore, the traditional solution of dissipating static electricity and preventing static electricity damage is no longer economical. At present, some solutions use a rubber ring structure between the cover and the display module, but this structure is relatively soft and easy to deform. Although it can meet the requirements in anti-static tests, it is easy to be damaged by external static electricity in actual use due to the deformation of the rubber ring, thereby damaging the smart watch and reducing the competitiveness of the product.

[0027] The utility model provides a liquid crystal display screen that complies with electrostatic testing, comprising a circular display module, a table cover is arranged above the circular display module, and an annular plastic protective shell is arranged below the table cover in a non-visible area, the plastic protective shell completely covers and wraps the outer side surface of the circular display module, the plastic protective shell comprises an abutment portion arranged at the top and a protective portion arranged below the abutment portion, the outer edge of the abutment portion is longer than the outer edge of the protective portion to form a step, the outer side surface of the abutment portion is flush with the outer side surface of the table cover, and the inner side surface of the protective portion is flush with the outer side surface of the circular display module.

[0028] The abutment part is used to support the watch cover and limit the position, and the protection part is equivalent to forming a barrier wall, which can effectively separate static electricity from the internal components. Put the watch cover on the plastic protective shell, and then press the plastic protective shell and the watch cover together with the whole machine casing through glue. This makes it very good to make the plastic protective shell firmly stick to the watch cover, play a role in blocking static electricity, and pass the test to meet the customer's static electricity requirements. The plastic protective shell is not easy to deform, and will not cause static electricity injuries due to deformation during actual use, thereby protecting the smart watch and improving the competitiveness of the product.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

In this embodiment, the circular display module 1 is blocked by the plastic protective shell 3, and the FPC led out of the circular display module 1 is marked in the figure. The plastic protective shell 3 includes an abutment portion 31 arranged at the top and a protective portion 32 arranged below the abutment portion 31. The outer edge of the abutment portion 31 is longer than the outer edge of the protective portion 32 to form a step, and the outer side surface of the abutment portion 31 is flush with the outer side surface of the table cover 2, and the inner side surface of the protective portion 32 is flush with the outer side surface of the circular display module 1. The abutment part 31 is used to support the watch cover 2 and limit the position, and the protection part 32 is equivalent to forming a barrier wall, which can well separate static electricity from the internal components. The watch cover 2 is put on the plastic protective shell 3, and then the plastic protective shell 3 and the watch cover 2 are pressed together with the whole machine casing through glue. This makes it very good to make the plastic protective shell 3 firmly adhere to the watch cover 2, play a role in blocking static electricity, and can meet the customer's static electricity requirements through testing. The plastic protective shell 3 is not easy to deform, and will not cause static electricity injuries due to deformation during actual use, thereby protecting the smart watch and improving the competitiveness of the product.

[0031] Furthermore, the thickness of the protection portion 32 is 0.68 mm.

[0032] Furthermore, the thickness of the abutting portion 31 is 0.2 mm.

[0033] Furthermore, the outer diameter of the abutting portion 31 is 45 mm.

[0034] Furthermore, the inner diameter of the abutting portion 31 is 41.6 mm.

Since the optical glue 22 is directly coated on the lower surface of the table cover 2 and extends to the lower surface of the ink layer 21, instead of being directly attached to the lower surface of the table cover 2 by using an optical glue 22 tape as in the traditional technology, the lower surface of the optical glue 22 can be formed into a smooth surface, and there is no height difference on the lower surface of the optical glue 22, so that the table cover 2 will not generate bubbles and edge yellow spots when it is attached, avoiding display abnormalities, thereby reducing the probability of defective products and significantly reducing production and manufacturing costs, thereby improving product competitiveness, thereby meeting the growing quality requirements of enterprises.
