[0002] With the rapid development of science and technology, wearable devices such as smart watches and bracelets have become an indispensable part of people's daily lives. Due to the frequent contact between wearable products and the human body, the anti-static requirements for wearable products are getting higher and higher. The wearable cover in current wearable products has a step design, that is, steps are formed at the edge and middle area of ​​the cover, making the thickness of the edge of the cover very thin. After installation, when the static electricity of the whole machine is tested, static electricity will enter the whole machine from the thinner edge and cannot be released, which will cause the whole machine to fail the static electricity test and fail to meet the high anti-static requirements of customers.

[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] See also Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a wearable display module 10 with an anti-static cover plate includes: a display screen 100 and a cover plate 200; the cover plate 200 is arranged on one side surface of the display screen 100, and a step structure is arranged on the side of the cover plate 200 away from the display screen 100, so that a groove 210 is formed at the edge of the cover plate 200, and a conductive shielding layer 211 is arranged on the surface of the groove 210.

[0025] It should be noted that the cover plate 200 on the existing display module 100 is usually designed with steps, that is, a groove 210 is formed at the edge of the cover plate, so that the edge of the cover plate is very thin. After the machine is installed, when the whole machine is subjected to an electrostatic test, static electricity will enter the whole machine from the edge and cannot be released. In this way, the electrostatic test of the whole machine will fail and the high anti-static requirements of the customer cannot be met. Therefore, in the present utility model, a conductive shielding layer 211 is provided on the groove 210 at the edge of the cover plate, and the conductive shielding layer 211 plays a shielding role on the static electricity, thereby preventing static electricity from entering the whole machine from the edge. Then, when the electrostatic test is performed, the high anti-static requirements of the customer can be met.

[0026] Preferably, the conductive shielding layer 211 is an ITO (indium tin oxide) layer. The ITO layer is a transparent material, so while playing an anti-static role, it does not affect the appearance of the cover plate 200. The ITO layer plays an electrostatic shielding role.

[0027] Preferably, the conductive shielding layer 211 is a metal layer, for example, copper metal.

[0028] In one embodiment, the display screen includes a polarizer 110, an upper glass 120, and a lower glass 130 stacked in sequence, and an optical glue 140 is disposed between the polarizer 110 and the cover plate 200. The upper glass 120 is a color filter glass, and the lower glass 130 is a thin film transistor glass. Preferably, the optical glue is an OCA (Optically Clear Adhesive, special adhesive) optical glue, which has high light transmittance and good bonding ability.

[0029] Furthermore, an ITO shielding layer is disposed on the entire side of the upper glass 120 facing the cover plate 200. A conductive tape is connected to one edge of the ITO shielding layer. After the wearable device is assembled, the conductive tape connects the ITO shielding layer to the housing of the wearable device, thereby playing an anti-static role.

[0030] Furthermore, one side of the lower glass 130 extends outward relative to the upper glass 120 to form a binding protrusion, and the binding protrusion is bound and connected to the FPC (flexible circuit board) 150. In another embodiment, the ITO shielding layer can also be connected to the grounding wiring on the lower glass 130 through silver paste routing, and then the binding position of the binding protrusion on the lower glass 130 is connected to the grounding wiring on the FPC, thereby achieving an anti-static effect.

[0031] Preferably, the total thickness of the cover plate 200 is 2 mm, and the width of the groove 210 is 1 mm. The thickness of the glass corresponding to the groove 210 is 0.7 mm.

[0032] In one embodiment, a DLC (diamond-like carbon) anti-scratch coating layer is disposed on one side of the cover plate 200 away from the display screen 100. The DLC anti-scratch coating layer has good optical transparency, higher hardness, lower friction coefficient, better wear resistance and anti-scratch ability, so the anti-scratch effect of the cover plate 200 can be improved.

[0033] In one embodiment, the side of the cover plate 200 away from the display screen 100 is also covered with a protective film 160, and a tear handle is provided on the edge of the protective film 160. The protective film 160 isolates and protects the outer surface of the cover plate 200, thereby preventing the cover plate from being stained during production and transportation.

[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.
