Technical Field

[0001] This utility model relates to the field of TFT liquid crystal module technology, specifically a multi-interface compatible TFT liquid crystal module. Background Technology

[0002] TFT LCD modules are the core components of LCD technology. They consist of an LCD panel, a backlight unit, and a driving circuit. Each pixel is independently controlled by a thin-film transistor (TFT) to achieve high resolution and high contrast. They are widely used in terminal devices such as smartphones, tablets, laptops, televisions, and automotive displays, and dominate in scenarios with high display quality requirements, such as power, transportation, and medical fields.

[0003] Currently, existing TFT LCD modules typically have multiple interfaces to enable compatible electrical connections for various circuits. However, after the interfaces are connected to external wiring, frequent pulling and tugging can cause the external wiring to loosen or even detach from the interfaces, leading to poor connections and instability. This is detrimental to the normal operation of the entire TFT LCD module. Therefore, a multi-interface compatible TFT LCD module is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-interface compatible TFT liquid crystal module to solve the problem mentioned in the background art that the external wiring that makes electrical connections with the interface in the existing TFT liquid crystal module may become loose or even detached during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-interface compatible TFT LCD module includes a backlight insulating panel. An integrated control circuit board is fixedly installed inside a shaped groove on the bottom surface of the backlight insulating panel.

A first fastening bolt is threaded into the circular groove on the top surface of the support. Guide posts are slidably connected to both sides of the movable frame. A push plate is fixedly connected to the side of the guide post closer to the inside of the movable frame. A clamping plate that is slidably connected to the limiting plate is fixedly connected to the side of the guide post away from the inside of the movable frame. A spring is sleeved on the outside of the guide post.

[0007] Preferably, a display screen is fixedly mounted on the top surface of the backlight insulating panel, the display screen and the integrated control circuit board are electrically connected, and a connection bus terminal is electrically connected to the middle position of the front end of the integrated control circuit board.

[0008] Preferably, the front left and right sides of the integrated control circuit board are each welded with an interface body, and there are a total of 6 interface bodies. The number of interface bodies corresponds one-to-one with the number of movable squares.

[0009] Preferably, the backlight insulating panel has round holes at the four corners of its top surface, and a second fastening bolt is threaded into the threaded slot at the front of the top surface of the backlight insulating panel and is connected to the limiting connecting rod.

[0010] Preferably, the clamping plates are arranged in groups of two, for a total of six groups. The lower end of the first fastening bolt penetrates the interior of the limiting plate and extends into the interior of the movable frame. The upper part of the opposite side of the left and right push plates is provided with a bevel structure. The left and right sides of the spring are fixedly connected to the clamping plates and the movable frame, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the inclusion of a support, limiting rod, limiting plate, movable frame, clamping plate, interface body, first fastening bolt, guide post, spring, and push plate facilitates the connection of the multi-interface compatible TFT LCD module to multiple external devices via multiple interface bodies. Under the connection constraints of the backlight insulating panel and upper sliding groove, the wiring connected to the interface body is secured by a multi-position clamping structure composed of the support, limiting rod, limiting plate, movable frame, clamping plate, interface body, first fastening bolt, guide post, spring, and push plate.

[0021] A multi-interface compatible TFT LCD module includes a backlight insulating panel 1. An integrated control circuit board 2 is fixedly installed inside a shaped groove on the bottom surface of the backlight insulating panel 1. An upper sliding groove 3 is provided on the top surface of the backlight insulating panel 1. A support 4 is slidably connected to the inner side of the upper sliding groove 3. A limiting plate 6 extending into the shaped groove on the bottom surface of the backlight insulating panel 1 is fixedly connected to the bottom of the support 4. A movable square frame 7 is fixedly connected to the bottom of the limiting plate 6. A limiting connecting rod 5 is fixedly connected to the top of the support 4. A first fastening bolt 10 is threadedly connected to the circular groove on the top surface of the support 4. Guide posts 11 are slidably connected to both the left and right sides of the movable square frame 7. A push plate 13 is fixedly connected to the side of the guide post 11 closer to the inside of the movable square frame 7. A clamping plate 8 that is slidably connected to the limiting plate 6 is fixedly connected to the side of the guide post 11 away from the inside of the movable square frame 7. A spring 12 is sleeved on the outside of the guide post 11.

[0022] A display screen 14 is fixedly mounted on the top surface of the backlight insulating panel 1. The display screen 14 and the integrated control circuit board 2 are electrically connected. A connection bus terminal 15 is electrically connected to the middle of the front end of the integrated control circuit board 2. The connection bus terminal 15 is designed to assist the TFT LCD module in quickly connecting to external terminal devices. Interface bodies 9 are soldered to both the left and right sides of the front end of the integrated control circuit board 2. There are a total of 6 interface bodies 9. The number of interface bodies 9 corresponds one-to-one with the number of movable frames 7. The reserved equipment of multiple interface bodies 9 can ensure that the entire TFT LCD module is compatible with various external wiring and improve adaptability. Circular holes 17 are opened at the four corners of the top surface of the backlight insulating panel 1. The front threaded slot on the top surface of the backlight insulating panel 1 is threaded with a second fastening bolt 16 that is connected to the limiting link 5. The round hole 17 is used to fix the backlight insulating panel 1, and the second fastening bolt 16 is used to assist in fixing the limiting link 5. There are six sets of clamping plates 8 in pairs. The lower end of the first fastening bolt 10 penetrates the interior of the limiting plate 6 and extends into the interior of the movable frame 7. The upper part of the opposite side of the left and right push plates 13 is provided with a beveled structure. The left and right sides of the spring 12 are fixedly connected to the clamping plate 8 and the movable frame 7, respectively. The beveled structure reserved on the upper part of one side of the push plate 13 is conducive to the downward screwing of the first fastening bolt 10 and the compression of the push plate 13.

[0023] Workflow: The TFT LCD module in this invention requires external power for all its operation. Before use, the entire TFT LCD module can be connected to the power system via the pre-reserved pin terminals on the integrated control circuit board 2, and connected to external terminal devices via the connection bus terminal 15, thus forming a complete display system. This technology is a publicly available prior art. When using this multi-interface compatible TFT LCD module, as the TFT LCD module is stably connected to the external terminal device via the connection bus terminal 15, during normal power-on operation of the external terminal device, the terminal device will send control commands to the TFT LCD module under a stable connection. The module can then receive and interpret the signals and display the corresponding data information on the display screen 14 for viewing. When multiple interface bodies 9 are needed for electrical connection to other external devices, the operator can select the appropriate interface body 9 according to the wiring type required by the other external device, align the connector with the inside of the interface body 9, and insert the corresponding connector, enabling the integrated control circuit board 2 to quickly connect to the external device via the interface body 9. Next, first screw the second fastening bolt 16 outward to loosen the constraint on the limiting link 5. Then, push the bracket 4 and the limiting plate 6 outward along the inside of the upper sliding groove 3 and the irregular groove. The multiple sets of clamps 8 and the movable frame 7 will be adjusted to the position directly in front of the interface body 9, and one set of clamps 8 will move exactly to the position directly above the wiring and the interface body 9. Then, screw the second fastening bolt 16 downward to connect the limiting link 5 with the threaded groove at the front end of the backlight insulating panel 1, and fix the position of the limited link 5 that has moved into place. At this time, under the connection constraint of the bracket 4, the first fastening is... Bolt 10 is adjusted by turning it upwards, removing the original squeezing force on push plate 13. Spring 12 begins to return to its original position, and the two clamping plates 8 move in the same direction with guide post 11 and push plate 13 to move closer together. Once in position, the TFT LCD module can be fixed by clamping the connected wiring pair through the two clamping plates 8, increasing its stability after connection with interface body 9. Subsequently, the corresponding first fastening bolt 10 can be adjusted and limited in the same way according to the actual connection position of the wiring, so that the TFT LCD module has the function of multi-position fixing.
