Technical Field

[0001] The utility model relates to the technical field of liquid crystal screens, in particular to a panel-bound liquid crystal display screen. Background Art

[0002] With the popularization of electronic products and the expansion of demand, LCD panel technology continues to develop, not only in terms of size, but also in terms of display effect and performance. The binding technology of LCD screens is an important part of LCD display technology. Traditional binding methods may have the problem of insufficient binding strength, which may lead to easy tearing and separation during use, thus affecting the electrical conductivity of the circuit. Therefore, the development of new binding technologies, such as the binding component design in panel-bound LCD screens, has become the key to improving the performance and stability of LCD screens.

[0003] After searching, the Chinese patent document application number: 202021577250.9 discloses a liquid crystal display screen, wherein the liquid crystal display screen includes a backlight unit and a display panel; the backlight unit includes a substrate, an LED light bar arranged on the substrate, and a light guide plate arranged on the light-emitting side of the LED light bar, and the LED light bar is used to connect with the mainboard; the display panel is connected to the LED light bar and is used to be exposed on the surface of the housing; the display panel is used to receive light emitted from the LED light bar and emitted through the light guide plate, and form a liquid crystal screen; wherein the substrate is concavely arranged and formed with an installation groove for installing the LED light bar.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 The utility model provides a technical solution: a panel-bound liquid crystal display screen, comprising a display screen body 1, a mounting frame 2 is installed around the outer wall of the display screen body 1, a current controller 8 is installed on one side of the display screen body 1, a binding component is arranged on one side of the current controller 8, the binding component comprises an upper binding substrate 9, a lower binding substrate 10, a plurality of conductive ends 12 and a conductive slot 14, one end of the upper binding substrate 9 is bonded and connected with one side of the current controller 8, a plurality of conductive ends 12 are evenly fixedly installed on the other end surface of the upper binding substrate 9, one end of the lower binding substrate 10 is bonded and connected with a panel 11, a plurality of conductive slots 14 are opened on the other end surface of the lower binding substrate 10, the surfaces of the conductive ends 12 and the conductive slots 14 are both coated with conductive glue, and the conductive ends 12 and the conductive slots 14 are connected by a plug-in component, and a heat dissipation component is arranged on the back side of the panel 11;

[0024] When in use, the design of the upper binding base 9 and the lower binding base 10 in the binding assembly makes the connection between the flexible circuit board and the panel 11 more stable. The coordinated use of the conductive end 12 and the conductive groove 14, combined with the application of the conductive glue, not only ensures the reliability of electrical conduction, but also greatly enhances the binding strength, which can effectively prevent tearing or separation during use. The heat dissipation assembly arranged on the back side of the panel 11 can effectively reduce the heat generated by the display screen body 1 during operation, prevent performance degradation or damage due to overheating, and not only extend the service life of the display screen body 1, but also improve its operating stability.

[0025] The plug-in assembly includes a plurality of plug-in rods 13 and a plug-in slot 15. The plurality of plug-in rods 13 are equidistantly installed on the surface of the conductive end 12. One end of the conductive end 12 is plugged into the conductive slot 14 through the plug-in rods 13 and the plug-in slot 15. By using the plurality of plug-in rods 13 and the plug-in slot 15 in coordination, the connection between the conductive end 12 and the conductive slot 14 can be made tighter and more stable. This plug-in method can effectively prevent loosening or separation during use, thereby greatly improving the stability and reliability of the binding.

[0026] An electronic component layer 3 is bonded to the inner wall of the display screen body 1, and a first OCA adhesive layer 4 is bonded to one side of the electronic component layer 3. Through the bonding of the first OCA adhesive layer 4, the internal structure of the display screen body 1 can be made more compact, and unnecessary gaps and spaces can be reduced, which helps to optimize the overall structure and improve the durability and impact resistance of the display screen body 1.

[0027] An ITO coating 5 is provided on one side of the first OCA adhesive layer 4, and a second OCA adhesive layer 6 is adhered to one side of the ITO coating 5. The ITO coating 5 has high light transmittance and can allow more light to pass through, thereby improving the brightness and clarity of the display screen body 1. The provision of the second OCA adhesive layer 6 makes the adhesion between the ITO coating 5 and subsequent components tighter and more stable. The second OCA adhesive layer 6 has excellent adhesion and optical properties, which can ensure a seamless connection between the ITO coating 5 and other parts of the display screen body 1 to prevent falling off or displacement during use.

[0028] One side of the second OCA adhesive layer 6 is connected to a thin film conductor layer 7, and one side of the thin film conductor layer 7 is bonded to one side of the current controller 8. The thin film conductor layer 7 serves as a medium for current transmission and is directly bonded to the current controller 8, which can significantly reduce the current loss during transmission and improve the conductive efficiency, thereby helping to ensure the stable operation of the display body 1 and improving the overall performance.

[0029] The heat dissipation assembly includes a heat dissipation box 16, a micro fan 21 and four heat-conducting columns 19, one end of the four heat-conducting columns 19 is fixedly connected to the back side of the panel 11, and the other end of the heat-conducting column 19 is fixedly connected to the surface of the heat dissipation box 16. A circular groove is opened in the center of the surface of the heat dissipation box 16, and the micro fan 21 is fixedly installed at the inner center of the heat dissipation box 16. The micro fan 21 generates airflow inside the heat dissipation box 16, and an effective heat dissipation channel is formed through the circular groove on the surface of the heat dissipation box 16 and the heat-conducting columns 19. The heat-conducting columns 19 can quickly transfer the heat generated on the panel 11 to the heat dissipation box 16, and then the airflow generated by the micro fan 21 takes the heat away, thereby achieving efficient heat dissipation.

[0030] The heat dissipation assembly also includes a heat absorbing plate 20 and heat dissipation holes 17. The heat absorbing plate 20 is fixedly installed around the inner wall of the heat dissipation box 16. The heat dissipation holes 17 are opened at both ends of the heat absorbing plate 20, and the heat dissipation holes 17 pass through both ends of the heat absorbing plate 20 and penetrate the inner wall of the heat dissipation box 16. Through the heat dissipation holes 17, the airflow generated by the micro fan 21 can be blown more directly onto the heat absorbing plate 20, thereby accelerating the convection and dissipation of heat. At the same time, the position of the heat dissipation holes 17 can ensure that the airflow forms an effective circulation inside the heat dissipation box 16, further improving the heat dissipation effect.
