[0002] Since the display module of LCD using IPS technology is sensitive to static electricity, the liquid crystal is easily affected by the static electricity on the surface of the LCD upper substrate and causes problems such as discoloration and uneven display.

When the display module needs to reduce the thickness, the original LCD needs to be washed => thinned => coated => cut. Re-coating increases both time and economic costs. The conductive film used in the traditional process cannot be re-coated after being cut into small pieces. When the coating is damaged during the process, problems such as discoloration and uneven display will occur, leading to increased costs. Utility Model Content

[0030] See also Figures 1 to 8 , shown is a non-film-coated LCD display module assembly fixture in an embodiment of the utility model, including a lower substrate 30 and an upper substrate 20 arranged above the lower substrate 30, a conductive upper polarizer 10 is attached to the surface of the upper substrate 20, the size of the lower substrate 30 is larger than the size of the upper substrate 20, so that the lower substrate 30 is away from the upper surface of the upper substrate 20 to form a dispensing platform 31, the size of the conductive upper polarizer 10 is larger than the size of the upper substrate 20, so that the conductive upper polarizer 10 is away from the upper surface of the upper substrate 20 A solid slurry platform 11 is formed on the lower surface of the substrate 20, and avoidance plates 32 are provided on the sides of the slurry dot platform 31 and the upper substrate 20. The non-film-coated LCD display module assembly fixture also includes a shaping workpiece 40. A side of the shaping workpiece 40 close to the conductive upper polarizer 10, the upper substrate 20 and the lower substrate 30 is recessed to form a first flow groove, and a side of the first flow groove close to the avoidance plate 32 is recessed to form a second flow groove 45, and the size of the second flow groove 45 matches the size of the avoidance plate 32.

[0031] It can be understood that the utility model attaches a conductive upper polarizer 10 to the surface of the upper substrate 20, wherein the resistance of the conductive upper polarizer 10 is 10 7 Ω~10 9 Ω, then a avoidance sheet 32 ​​is provided on the side of the dispensing platform 31 and the upper substrate 20, and a shaping workpiece 40 is provided on the side of the conductive upper polarizer 10, the upper substrate 20 and the lower substrate 30, and the conductive silver paste 60 is dispensed from the shaping workpiece 40, and the conductive silver paste 60 is attached to the side of the conductive upper polarizer 10, the solid slurry platform 11, the side of the upper substrate 20, the avoidance sheet 32, and the dispensing platform 31 from top to bottom. Due to the conductivity and shielding properties of the conductive upper polarizer 10, the lower substrate 30 is connected with the conductive silver paste 60 to release static electricity, so that the formed display module has an anti-static function, so there is no need to plate a conductive film on the surface of the upper substrate 20 as in the prior art, which causes the trouble of later repair; at the same time, due to the setting of the shaping workpiece 40, the conductive silver paste 60 will not be used, so that the conductive silver paste 60 will not flow into the display area of ​​the display module from the gap between the dispensing platform 31 and the upper substrate 20, causing screen necrosis.

[0032] Specifically, in the present embodiment, the shaping workpiece 40 is provided with a flow blocking portion 46 on both sides close to the conductive upper polarizer 10, the upper substrate 20 and the lower substrate 30, and the first flow groove is formed in the flow blocking portion 46; the first flow groove includes a first bonding surface 41 corresponding to the side wall of the conductive upper polarizer 10, a second bonding surface 42 corresponding to the solid slurry platform 11, a third bonding surface 43 corresponding to the side wall of the lower substrate 30, and a fourth bonding surface 44 corresponding to the slurry dot platform 31; the two ends of the avoidance plate 32 are inclined.

[0033] It can be understood that the conductive silver paste 60 is dotted from the top of the shaping workpiece 40 and flows downward along the two flow-blocking parts 46. There is a flow space for the conductive silver paste 60 to flow between the first bonding surface 41 and the side wall of the conductive upper polarizer 10, between the second bonding surface 42 and the solid paste platform 11, between the third bonding surface 43 and the side wall of the lower substrate 30, and between the fourth bonding surface 44 and the dot paste platform 31, so that the conductive silver paste 60 flows through the flow space and is shaped. The shaped conductive silver paste 60 is bonded to the conductive upper polarizer 10, the upper substrate 20, and the lower substrate 30. The plates 30 fit tightly together and have high strength, so that the formed display module is both timely and economical. Due to the setting of the avoidance sheet 32, the conductive silver paste 60 will not flow into the display area of ​​the display module from the gap between the paste dispensing platform 31 and the upper substrate 20 to cause screen necrosis; the inclined settings at both ends of the avoidance sheet 32 ​​can better guide the conductive silver paste 60 to flow from the inclined part into the surface of the avoidance sheet 32, and then flow out from the surface of the avoidance sheet 32 ​​to the paste dispensing platform 31, thereby avoiding the conductive silver paste 60 from getting stuck at the avoidance sheet 32, resulting in poor fluidity.

[0034] Furthermore, two second flow grooves 45 are provided in the shaping workpiece 40 , and each of the second flow grooves 45 corresponds to one avoidance plate 32 ; there are two shaping workpieces 40 , and the two shaping workpieces 40 are respectively arranged at two ends of the slurry dispensing platform 31 .

[0035] It can be understood that two avoidance plates 32 are respectively provided at both ends of the entire display module, and two second flow grooves 45 corresponding to the avoidance plates 32 are provided on each molding workpiece 40. Therefore, a molding workpiece 40 is required at both ends of the entire display module. After the silver paste is fixed with the molding workpiece 40, the molding workpiece 40 can be removed.

[0036] Furthermore, the upper surface of the upper substrate 20 is covered with a glass cover plate 50 , and an optical adhesive layer is provided between the upper substrate 20 and the glass cover plate 50 ; the lower surface of the lower substrate 30 is provided with a lower polarizer (not shown in the figure).

[0037] The above structure can form a complete display module.

[0038] In summary, the non-film-coated LCD display module assembly fixture in the above embodiment of the utility model is provided with a conductive upper polarizer attached to the surface of the upper substrate, wherein the resistance of the conductive upper polarizer is 10 7 Ω~10 9 Ω, then avoidance sheets are provided on the sides of the paste-dotting platform and the upper substrate, and shaping workpieces are provided on the sides of the conductive upper polarizer, the upper substrate and the lower substrate, and the conductive silver paste is dotted from the shaping workpiece, and the conductive silver paste is attached to the side of the conductive upper polarizer, the solid paste platform, the side of the upper substrate, the avoidance sheet, and the paste-dotting platform from top to bottom. Due to the conductivity and shielding properties of the conductive upper polarizer, the lower substrate is connected through the conductive silver paste to release static electricity, so that the formed display module has an anti-static function, so there is no need to plate a conductive film on the surface of the upper substrate as in the prior art, which causes the trouble of later repair; at the same time, due to the setting of the shaping workpiece, the conductive silver paste will not flow into the display area of ​​the display module from the gap between the paste-dotting platform and the upper substrate to cause screen necrosis due to the use of the conductive silver paste.
