Description

Technical Field

[0001] This utility model relates to the technical field of fully laminated display modules, and particularly to an anti-backlight detachment device for a fully laminated display module. Background Art

[0002] A fully laminated display module (also known as "full lamination" or "OGS - One Glass Solution") is a display manufacturing technology that reduces the air gap between traditional touch screen layers, thereby improving the display effect and user experience. In a traditional touch screen structure, there is usually an air layer between the touch sensor layer and the LCD or OLED display layer. This design can cause light refraction and reflection problems, affecting the clarity and color performance of the screen. Generally, the laminated structure of a fully laminated display module consists of a touch screen + optical adhesive + liquid crystal display panel + backlight. In this way, the touch screen is adhered to the liquid crystal display panel, and the backlight is suspended under the liquid crystal display panel, making it easy for the backlight to separate and fall off. Especially for large-size modules, the backlight is relatively heavy and more likely to fall off. At the same time, the existing display module has poor heat dissipation efficiency, which easily leads to a continuous increase in the internal temperature, and then causes the internal structure to expand due to heat, resulting in a shift in the position between the internal structures, making the local brightness uneven, as well as image distortion or blurring. Content of the Utility Model

[0003] Based on this, in view of the above technical problems, it is necessary to provide an anti-backlight detachment device for a fully laminated display module. Through the positioning and reinforcement components, the connection between the backlight glue frame and the cover plate can be strengthened, avoiding the backlight glue frame from falling off under the action of gravity, resulting in the loss of support for the internal structure and causing the internal parts to fall and separate. Moreover, the fixing components are located outside the VA area and will not affect the display effect.

[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions:

The heat dissipation component is arranged on the peripheral sides of the upper glass sheet and the lower glass sheet of the liquid crystal display panel for heat dissipation and temperature reduction. The heat dissipation component includes: a heat-conducting edge, a heat dissipation plate, and a heat-conducting block. By means of the heat dissipation component, the heat dissipation efficiency is improved, and it is avoided that the temperature inside the backlight rubber frame is too high, causing the internal structure to expand due to heat, resulting in the displacement of the positions between the internal structures, leading to uneven brightness, as well as image distortion or blurring.

[0033] A backlight rubber frame 1, on which a lower polarizer 11 is provided. On the top of the lower polarizer 11, a lower glass sheet of the liquid crystal display panel 12 is provided.

[0036] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0038] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0039] Please refer to Figure 1-2, An anti-backlight detachment device for a fully laminated display module, comprising: a backlight rubber frame 1, a lower polarizer 11 is provided on the backlight rubber frame 1, a lower glass sheet of the liquid crystal display panel 12 is provided on the top of the lower polarizer 11, an upper glass sheet of the liquid crystal display panel 13 is provided on the top of the lower glass sheet of the liquid crystal display panel 12, an upper polarizer 14 is provided on the top of the upper glass sheet of the liquid crystal display panel 13, a cover plate 15 is provided above the upper polarizer of the backlight rubber frame 1, and a touch sensor 18 is provided on the bottom of the cover plate 15; a reinforcement component, which is arranged outside the backlight rubber frame 1 and is used for supporting and fixing the backlight rubber frame 1. The reinforcement component includes: a steel sheet 2, a double-sided adhesive 21, and a soft foam 22; steel sheets 2 are respectively provided on the opposite sides of the outside of the backlight rubber frame 1, double-sided adhesives 21 are respectively provided between the tops of the two steel sheets 2 and the bottom of the touch sensor 18, and soft foams 22 are respectively provided between the bottom of the backlight rubber frame 1 and the inner bottom walls of the two steel sheets 2.

[0040] The display module is composed of the lower polarizer 11, the lower glass sheet of the liquid crystal display panel 12, the upper glass sheet of the liquid crystal display panel 13, and the upper polarizer 14. The cover plate 15 and the touch sensor 18 form a touch control module. The display module and the touch control module are used together. The backlight rubber frame 1 is used to support the above structures, and the reinforcement component is used to reinforce the backlight rubber frame 1 to prevent the backlight rubber frame 1 from falling off.

[0041] On the basis of Embodiment 1, the two steel sheets 2 are arranged in a right-angled Z-shaped structure, and the two steel sheets 2 are symmetrically arranged. The backlight rubber frame 1 is located between the two right angles of the two steel sheets 2. The soft foam 22 is made of polyethylene foam material as a whole, and the double-sided adhesive 21 is made of acrylic material as a whole.

[0042] When installing the backlight rubber frame 1, the double-sided adhesive 21 is pasted on the tops of the two steel sheets 2, and the steel sheets 2 are connected to the bottom of the touch sensor 18 through the double-sided adhesive 21 to support the backlight rubber frame 1 and prevent the backlight rubber frame 1 from falling off. Subsequently, the two steel sheets 2 are respectively placed on the opposite sides of the backlight rubber frame 1 so that the backlight rubber frame 1 is located between the two steel sheets 2, and the soft foam 22 made of polyethylene foam material is pasted between the bottom of the backlight rubber frame 1 and the inner bottom of the steel sheet 2. The soft foam 22 made of polyethylene foam material has strong heat insulation and buffering performance, can isolate external heat conduction, and plays a buffering role during collisions. The double-sided adhesive 21 made of acrylic material has strong adhesion, and tearing off the double-sided adhesive 21 will not leave glue marks, and has strong heat resistance and long service life, avoiding the situation that the adhesion is reduced due to heat, resulting in unstable connection between the steel sheet 2 and the touch sensor 18, and further causing the backlight rubber frame 1 to fall off. Moreover, "Z"-shaped steel sheets can be pasted around or on both sides of the backlight rubber frame 1 to support the backlight rubber frame 1, and the supported part needs to be outside the VA area of the display module so as not to affect the display effect.

[0043] On the basis of Embodiment 1, please refer toFigures 3-6 Further, it also includes a heat dissipation component, which is arranged on the peripheral sides of the upper glass 13 and the lower glass 12 of the liquid crystal display panel for heat dissipation and temperature reduction. The heat dissipation component includes: a heat-conducting edge 3, a heat dissipation plate 31 and a heat-conducting block 32. By means of the heat dissipation component, the heat dissipation efficiency is improved, thermal expansion is reduced, and it is avoided that the internal structure of the display module expands due to heat, resulting in position deviation and uneven brightness.

[0044] A heat-conducting edge 3 is arranged on the peripheral sides of the upper glass 13 and the lower glass 12 of the liquid crystal display panel. The inner wall of the heat-conducting edge 3 is attached to the lower polarizer 11, the lower glass 12 of the liquid crystal display panel, the upper glass 13 of the liquid crystal display panel and the lower glass 12 of the liquid crystal display panel. Heat dissipation plates 31 are respectively arranged on the opposite sides of the two steel sheets 2. Heat-conducting blocks 32 are respectively fixedly connected to the opposite sides of the heat-conducting edge 3. The heat-conducting edge 3 is made of a flexible heat-conducting silica gel material, and the inside of the heat-conducting edge 3 is arranged in a honeycomb shape. A plurality of heat dissipation fins 33 are respectively fixedly connected to the opposite sides of the two heat dissipation plates 31. The plurality of heat dissipation fins 33 are equidistantly distributed. Through holes 34 are respectively formed in the opposite sides of the backlight rubber frame 1 and the steel sheet 2. The opposite ends of the two heat-conducting blocks 32 respectively penetrate through the through holes 34 and are connected to the two heat dissipation plates 31.

[0045] When the display module is in use, heat will be generated. Since the added steel sheet 2 will affect heat dissipation, a large amount of this heat will gather in the space between the backlight rubber frame 1, the touch sensor 18 and the steel sheet 2, which will further cause the temperature of the display module to rise. The heat dissipation edge 3 absorbs the heat dissipated by the display module. The heat dissipation edge 3 is attached to the display module, increasing the contact area, and can better absorb the heat dissipated by the display module. Then the heat is transferred to the heat-conducting block 32, and then the heat is transferred from the heat-conducting block 32 to the heat dissipation plate 31. The heat is dissipated to the external air through the heat dissipation plate 31. The setting of the heat dissipation fins 33 can increase the heat dissipation area and improve the heat dissipation efficiency. Furthermore, it can avoid the thermal expansion of other objects such as the lower polarizer 11, the lower glass 12 of the liquid crystal display panel, the upper glass 13 of the liquid crystal display panel and the upper polarizer 14, resulting in position deviation between them, affecting uneven brightness and normal display function. The heat dissipation edge 3 restricts structures such as the lower polarizer 11, the lower glass 12 of the liquid crystal display panel, the upper glass 13 of the liquid crystal display panel and the upper polarizer 14, reducing the expansion coefficient. When the structure expands, it will squeeze the peripheral heat dissipation edge 3. The honeycomb structure inside the heat dissipation edge 3 buffers the expansion length, and the heat dissipation edge 3 made of heat-conducting silica gel material has good heat conductivity and buffering function, and can protect the internal structure of the display module.

[0046] Wherein, an optical bonding adhesive 16 is provided between the top of the upper polarizer 14 and the touch sensor 18. The optical bonding adhesive 16 has the same size as the upper polarizer 14. The upper polarizer 14 is connected to the touch sensor 18 through the optical bonding adhesive 16, further reducing the air gap between the upper polarizer 14 and the touch sensor 18, thereby improving the display effect.

[0047] Wherein, a backlight light-shielding adhesive 17 is provided between the top of the backlight rubber frame 1 and the bottom of the lower polarizer 11. The size of the backlight light-shielding adhesive 17 is equal to the inner bottom of the backlight rubber frame 1. The backlight rubber frame 1 is adhered to the bottom of the lower polarizer 11 through the backlight light-shielding adhesive 17. In this pasting scheme, since the backlight rubber frame 1 is suspended on both sides of the backlight light-shielding adhesive 17 and there is no blocking wall on the backlight rubber frame 1, the backlight rubber frame 1 and the lower polarizer 11 are easily separated.

[0048] The usage process of the automatic column passing device provided by the present utility model is as follows: When installing the backlight rubber frame 1, double-sided adhesive 21 is pasted on the top of two steel sheets 2, and the steel sheets 2 are connected to the bottom of the touch sensor 18 through the double-sided adhesive 21, so as to support the backlight rubber frame 1 and prevent the backlight rubber frame 1 from falling off. Subsequently, the two steel sheets 2 are respectively placed on the opposite sides of the backlight rubber frame 1, so that the backlight rubber frame 1 is located between the two steel sheets 2, and a soft foam 22 is pasted between the bottom of the backlight rubber frame 1 and the inner bottom of the steel sheet 2. The soft foam 22 made of polyethylene foam material has strong heat insulation and buffering properties, can isolate external heat conduction, and play a buffering role during collision. The double-sided adhesive 21 made of acrylic material has strong adhesion, will not leave glue marks when the double-sided adhesive 21 is torn off, has strong heat resistance and a long service life, avoids the reduction of adhesion caused by heat, resulting in unstable connection between the steel sheet 2 and the touch sensor 18, and further causing the backlight rubber frame 1 to fall off. Moreover, "Z"-shaped steel sheets can be pasted around or on both sides of the backlight rubber frame 1 to support the backlight rubber frame 1, and the supported part needs to be outside the VA area of the display module, so as not to affect the display effect. The upper polarizer 14 is connected to the bottom of the optical bonding adhesive 16 through the optical bonding adhesive 16, further reducing the air gap between the upper polarizer 14 and the cover plate 15, so as to improve the display effect. The backlight rubber frame 1 is pasted to the bottom of the lower polarizer 11 through the backlight light-shielding adhesive 17. In this pasting scheme, since the backlight rubber frame 1 is suspended on both sides of the backlight light-shielding adhesive 17 and there is no barrier wall on the backlight rubber frame 1, the backlight rubber frame 1 and the lower polarizer 11 are easily separated, resulting in the backlight rubber frame 1 falling off. Moreover, the supported area of the two steel sheets 2 is far from the VA area to prevent affecting the display effect. The heat dissipation edge 3 absorbs the heat dissipated by the display module. The heat dissipation edge 3 is attached to the display module to increase the contact area, and can better absorb the heat dissipated by the display module, and then transfer the heat to the heat conduction block 32. Subsequently, the heat is transferred from the heat conduction block 32 to the heat dissipation plate 31, and the heat is dissipated to the external air through the heat dissipation plate 31. The setting of the heat dissipation fins 33 can increase the heat dissipation area and improve the heat dissipation efficiency, thereby avoiding the thermal expansion of other objects such as the lower polarizer 11, the lower glass sheet of the liquid crystal display panel 12, the upper glass sheet of the liquid crystal display panel 13, and the upper polarizer 14, causing the positions between them to shift, affecting the uneven brightness and normal display function. The heat dissipation edge 3 restricts structures such as the lower polarizer 11, the lower glass sheet of the liquid crystal display panel 12, the upper glass sheet of the liquid crystal display panel 13, and the upper polarizer 14, reducing the expansion coefficient. When the structure expands, it will squeeze the surrounding heat dissipation edge 3, and the honeycomb structure inside the heat dissipation edge 3 buffers the expansion length. Moreover, the heat dissipation edge 3 made of heat-conducting silica gel material has good heat conductivity and buffering function, and can protect the internal structure of the display module.
