Description

Technical Field

[0001] This utility model relates to a display module, and more particularly to an enhanced liquid crystal panel optical bonding display module and a display front module. Background Technology

[0002] Optical bonding technology is a technique that uses optical adhesive to seamlessly bond a liquid crystal panel (LCD) panel to glass. Currently, the structure obtained by first bonding the LCD panel and glass using optical bonding technology, then bonding it to the backlight module and sealing the perimeter with adhesive is called an open cell bonding display module (LCD module). The LCD panel and backlight module together form the LCD display module. Optical bonding technology eliminates air gaps between the LCD panel and glass, significantly reducing light reflection while increasing transmission, resulting in low light leakage and a marked improvement in display brightness and effect. It is now widely used. However, in practical use, existing open cell bonding display modules have weak overall strength due to the lack of protection around the LCD module, leading to the following problems: irreversible deformation upon impact; micro-deformation during mounting, resulting in yellow spots and increased light leakage; and when embedded in the front frame to form the front module of a display, the gap between the outer edge of the glass and the perimeter of the front frame, as well as the front-to-back distance between the glass and the front frame, are uncontrollable, making product quality unreliable. Utility Model Content

[0003] The purpose of this utility model is to provide an enhanced liquid crystal panel optical bonding display module and a display front module, which has good structural strength, is not prone to deformation, yellow spots, light leakage and other defects, and the position between the glass and the front frame is controllable, and the product quality is reliable.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An enhanced liquid crystal panel optical bonding display module includes a liquid crystal display module. The liquid crystal panel of the liquid crystal display module is seamlessly bonded to glass with optical adhesive to form the liquid crystal panel optical bonding display module. The glass extends out of the liquid crystal display module around its perimeter. An upper sheet metal bracket is fixed to the upper side of the liquid crystal display module and is close to the glass. A lower sheet metal bracket is fixed to the lower side of the liquid crystal display module and is close to the glass. Side metal brackets are fixed to both sides of the liquid crystal display module and are close to the glass. Reinforcing adhesive is applied to the gaps between the upper sheet metal bracket and the glass, the gaps between the lower sheet metal bracket and the glass, and the gaps between the side metal brackets and the glass.

[0006] A display front module includes a front frame and an enhanced liquid crystal panel optically bonded display module, wherein the enhanced liquid crystal panel optically bonded display module is locked onto the front frame.

[0007] The advantages of this utility model are:

[0008] This utility model, through the design of upper and lower sheet metal brackets and two side metal brackets, greatly enhances the strength of the overall structure, making it less prone to deformation when subjected to impact, reducing the degree of micro-deformation during hanging, effectively reducing adverse optical phenomena such as yellow spots and increased light leakage. Furthermore, it can effectively absorb the positional deviation caused by the LCD panel during the bonding process with the glass. The gap between the outer edge of the glass and the four sides of the front frame, as well as the front and rear section difference between the glass and the front frame, are controllable, ensuring product quality.

[0015] like Figures 1 to 4 As shown, this utility model proposes an enhanced liquid crystal panel optical bonding display module 50, including a liquid crystal display module 12. The liquid crystal panel of the liquid crystal display module 12 is seamlessly bonded to the glass 11 with optical adhesive to form a liquid crystal panel optical bonding display module 10. Generally, the glass 11 extends a certain length from the liquid crystal display module 12 around its perimeter. As shown in the figure, an upper sheet metal bracket 21 is fixed on the upper side of the liquid crystal display module 12 and is close to the glass 11. A lower sheet metal bracket 22 is fixed on the lower side of the liquid crystal display module 12 and is close to the glass 11. Side metal brackets 23 are fixed on both sides of the liquid crystal display module 12 and are close to the glass 11. The gaps between the upper sheet metal bracket 21 and the glass 11, the gaps between the lower sheet metal bracket 22 and the glass 11, and the gaps between the side metal brackets 23 and the glass 11 are coated with reinforcing adhesive 30.

[0016] Here, the upper sheet metal bracket 21, the lower sheet metal bracket 22 and the side metal bracket 23 are all located close to the glass 11, and there is generally a gap of about 1mm between them and the glass 11, so as to avoid the glass 11 from breaking due to vibration and impact if they are in direct contact.

[0017] like Figure 2 The upper sheet metal bracket 21 includes an upper strip plate 211 and an upper retaining edge 212. The upper strip plate 211 and the upper retaining edge 212 are connected to form an L-shape. Preferably, the upper strip plate 211 and the upper retaining edge 212 are formed into an L-shape by bending a plate. The upper strip plate 211 is provided with an upper locking hole 213. The upper strip plate 211 is located on the upper surface of the liquid crystal display module 12 and is close to the rear side of the glass 11. The upper retaining edge 212 is close to the rear side of the liquid crystal display module 12. The upper locking hole 213 on the upper strip plate 211 is opposite to the fixing hole on the upper surface of the liquid crystal display module 12, so that the upper sheet metal bracket 21 is locked to the upper surface of the liquid crystal display module 12 by a fastener 40 (such as a screw). The fastener 40 passes through the upper locking hole 213 on the upper strip plate 211 and is screwed into the fixing hole on the upper surface of the liquid crystal display module 12.

[0018] like Figure 3 The lower sheet metal bracket 22 includes a flat lower strip 221, the shape of which can be designed according to actual requirements. Figure 3 The lower strip 221 is shown to be slightly narrower than the other half. The lower strip 221 is provided with a lower locking hole 222. The lower strip 221 is located on the lower surface of the liquid crystal display module 12 and close to the rear side of the glass 11. The lower locking hole 222 on the lower strip 221 is opposite to the fixing hole on the lower surface of the liquid crystal display module 12, so that the lower sheet metal bracket 22 is locked to the lower surface of the liquid crystal display module 12 by a fastener 40 (such as a screw). (The fastener 40 passes through the lower locking hole 222 on the lower strip 221 and is screwed into the fixing hole on the upper surface of the liquid crystal display module 12.)

[0019] like Figure 4The side metal bracket 23 includes a side strip 231 and a side retaining edge 232. The side strip 231 and the side retaining edge 232 are connected to form an L-shape. Preferably, the side strip 231 and the side retaining edge 232 are formed into an L-shape by machining. The side strip 231 is provided with a side locking hole 233, and the side retaining edge 232 is provided with an assembly hole 234. The assembly hole 234 is used to be aligned with the matching hole 63 on the front frame 60. The side strip 231 is located on the side of the liquid crystal display module 12. And close to the rear side of the glass 11, the side strip 231 is close to the rear side of the liquid crystal display module 12; the side locking hole 233 on the side strip 231 is opposite to the fixing hole on the side surface of the liquid crystal display module 12, so that the side metal bracket 23 is locked to the side of the liquid crystal display module 12 by the fastener 40 (such as screw) (the fastener 40 passes through the side locking hole 233 on the side strip 231 and is screwed into the fixing hole on the side surface of the liquid crystal display module 12).

[0020] In practice, the fixing holes on the upper and lower surfaces of the liquid crystal display module 12 are generally existing threaded holes. Of course, if the upper and lower surfaces of the liquid crystal display module 12 do not have threaded holes, threaded holes can be opened on the upper surface of the liquid crystal display module 12 according to the upper locking hole 213 and threaded holes can be opened on the lower surface of the liquid crystal display module 12 according to the lower locking hole 222.

[0021] Similarly, the fixing holes on the side of the liquid crystal display module 12 are generally reserved threaded holes. Of course, if there are no threaded holes on the side of the liquid crystal display module 12, threaded holes can be opened on the side of the liquid crystal display module 12 according to the side locking hole 233.

[0022] Preferably, the side locking hole 233 is a horizontally elongated oval hole, that is, compared with the vertical direction, the side locking hole 233 is longer in the front-to-back direction. The design of the horizontally elongated oval hole is used to effectively absorb the positional deviation of the liquid crystal panel of the liquid crystal display module 12 during bonding with the glass 11, and ensure the uniformity of the gap between the glass 11 and the front frame 60 after the reinforced liquid crystal panel optical bonding display module 50 of this utility model is assembled with the front frame 60.

[0023] In this utility model, except for the side lock attachment hole 233 which is an oblong hole, all other holes can be round holes, and there is no limitation thereto.

[0024] like Figure 4 Preferably, the side locking hole 233 is located within the groove 2330 provided on the side strip 231 of the side metal bracket 23. This design ensures that the fastener 40 does not protrude from the side metal bracket 23 after locking, thereby reducing the space occupied by the product.

[0025] In the actual design, the reinforcing adhesive 30 is made of polyurethane (PU). During manufacturing, a strip of reinforcing adhesive 30 is applied between the upper sheet metal bracket 21 and the glass 11, between the lower sheet metal bracket 22 and the glass 11, and between the side metal bracket 23 and the glass 11. Figure 5 The reinforcing adhesive 30 applied between the upper sheet metal bracket 21 and the glass 11 is only shown schematically. This design can further enhance the strength of the overall structure and effectively enhance its ability to resist flexural deformation.

[0026] In this utility model, the upper sheet metal bracket 21 and the lower sheet metal bracket 22 are made of stainless steel, and the side metal bracket 23 is made of aluminum alloy, which is not a limitation.

[0027] In actual production, it is advisable to use machining for the side metal bracket 23, which has the advantage of high manufacturing precision.

[0028] like Figure 5 and Figure 6 The present invention also proposes a display front module 80, including a front frame 60 and the present invention's enhanced liquid crystal panel optical bonding display module 50, which is locked onto the front frame 60.

[0029] like Figure 5 The front frame 60 includes a frame composed of four frame edges 61. Each frame edge 61 extends inward with a protruding edge 62. Matching holes 63 are provided on the protruding edges 62 on both sides. The matching holes 63 on each protruding edge 62 are opposite to the corresponding mounting holes 234 on the side locking edge 232 of the side metal bracket 23, so that the front frame 60 is locked to the side metal bracket 23 on the enhanced liquid crystal panel optical bonding display module 50 of this utility model by means of an accessory 70 (such as a screw), thereby realizing the fixation between the front frame 60 and the enhanced liquid crystal panel optical bonding display module 50 of this utility model (the accessory 70 passes through the matching holes 63 on the front frame 60 and is screwed into the mounting holes 234 on the side metal bracket 23).

[0030] In actual design, matching holes can also be provided on the upper and lower convex edges 62 of the front frame 60. Correspondingly, the corresponding components of the enhanced liquid crystal panel optical bonding display module 50 of this utility model have holes that are aligned with the matching holes, which will not be described here.

[0031] In actual assembly, after the front frame 60 is assembled with the enhanced liquid crystal panel optical bonding display module 50 of this utility model, the enhanced liquid crystal panel optical bonding display module 50 is embedded in the front frame 60. That is, the enhanced liquid crystal panel optical bonding display module 50 is entirely located within the front frame 60, the front surface of the glass 11 is approximately flush with the front surface of the front frame 60, and the outer edges of the glass 11 are separated from the inner surfaces of the front frame 60 by a certain gap. From the actual assembly effect, the above-mentioned structure of the display front module 80 of this utility model makes the gap between the outer edge of the glass 11 and the inner surfaces of the front frame 60 uniform and constant (or controllable), and makes the front-to-back step difference (in the front-to-back direction) between the glass 11 and the front frame 60 controllable and constant.

[0032] In this invention, the front-to-back direction is defined by the structure of the enhanced liquid crystal panel optical bonding display module 50 or the front module 80 of the display (e.g., Figure 5 The glass 11 is located at the front, and the liquid crystal display module 12 is located at the rear. Furthermore, since the front module 80 of this invention is located in front of the display, it is referred to as the "front module".

[0033] The advantages of this utility model are:

[0034] This utility model, through the design of upper and lower sheet metal brackets and two side metal brackets, greatly enhances the overall structural strength, making it less prone to deformation under impact and reducing the degree of micro-deformation during hanging. It effectively reduces adverse optical phenomena such as yellow spots and increased light leakage. Furthermore, it can effectively absorb the positional deviation caused by the LCD panel during the bonding process with the glass, and can control the gap between the outer edge of the glass and the four sides of the front frame, as well as the front and rear section difference between the glass and the front frame, ensuring product quality.

[0035] The above describes the preferred embodiment of this utility model and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solution of this utility model without departing from the spirit and scope of this utility model shall fall within the protection scope of this utility model.
