[0002] With the development of the times, the requirements of electronic products for human-computer interaction are gradually increasing. Display screens can enable users to obtain information more intuitively and conveniently, so LED displays are widely used in more and more usage scenarios.

[0003] The LED display driver chip is the main part of the LED display imaging system. It integrates components such as resistors, regulators, comparators and power transistors, including LCD modules and display subsystems. It is responsible for driving the display and controlling driving current and other functions. It is divided into two methods: static drive and dynamic drive. The display driver chip can drive various high, medium and low performance, single, dual and full-color display screens according to different performance. It is widely used in various industries and government departments such as telecommunications, postal services, finance, transportation, stadiums, etc. The serial interface is the channel connecting the display driver chip and the display screen. Data is exchanged through the serial line connected to the serial interface. However, traditional serial lines are generally connected by snap-in, which is relatively simple. The interface is easy to loosen during use, which can easily cause the display screen to be distorted. Summary of the Invention

[0022] See also Figure 1-4 The present invention provides a technical solution: an LED display driver chip, comprising a housing 1, an integrated circuit board 3 fixedly connected to the interior of the housing 1 through a column 2, a display driver chip body 4 mounted on the top of the integrated circuit board 3, a serial interface 5 provided on one side of the integrated circuit board 3, and the serial interface 5 extends to the outside of the housing 1 away from one end of the integrated circuit board 3; a fixing sleeve 6 fixedly connected to the outer side of the housing 1, and the fixing sleeve 6 is covered on the outside of the serial interface 5; a fixing mechanism 8 for stabilizing the serial line connector 7 is provided on the top of the fixing sleeve 6, a clamping plate 9 fixedly connected to the outside of the housing 1 in the fixing sleeve 6, and the clamping plate 9 is engaged with a clamping groove 10 provided on the serial line connector 7, so as to improve the connection stability between the serial line connector 7 and the serial interface 5.

[0023] Furthermore, the fixing mechanism 8 includes a pull ring 81, and arc-shaped elastic sheets 82 are symmetrically fixed on both sides of the pull ring 81. The bottom ends of the arc-shaped elastic sheets 82 are fixed with connecting blocks 83. A sliding rod 84 passes through the two connecting blocks 83, and one end of the sliding rod 84 is fixed to the outer wall of the shell 1; a positioning rod 85 is fixed to the bottom of the pull ring 81, and the bottom end of the positioning rod 85 is inserted into the fixing sleeve 6 and the snap-fit groove 10 and is connected with a snap-fit plate 9, which is used to further improve the stability of the serial line connector 7 and the serial interface 5, so that the serial line connector 7 and the serial interface 5 are not easy to loosen, which can ensure continuous data transmission and thus solve the problem of flowery screen on the display screen.

[0024] Furthermore, a sliding hole 86 with two ends communicating is opened inside the connecting block 83 , and the sliding hole 86 is slidably sleeved on the outside of the sliding rod 84 .

[0025] Furthermore, movable grooves 87 are connected to each other on both sides of the positioning rod 85. The internal height of the movable groove 87 is greater than the height of the slide rod 84, and the slide rod 84 can move through the movable groove 87 without hindering the movement of the pull ring 81.

[0026] Furthermore, a first through slot 11 is formed at the top of the fixing sleeve 6 corresponding to the positioning rod 85 , and the first through slot 11 is adapted to fit the positioning rod 85 .

[0027] Furthermore, a second through slot 12 communicating with the engaging slot 10 is formed on the top of the serial line connector 7 . The second through slot 12 is corresponding to the first through slot 11 and has the same specifications.

[0028] Furthermore, a connection groove 13 for engaging with the positioning rod 85 is formed on the engaging plate 9 at a position corresponding to the first through groove 11 .

[0029] Working principle: When the LED display driver chip provided by the present invention is used to connect the serial line connector 7 to the serial interface 5, the pull ring 81 is pulled, the arc-shaped elastic piece 82 is deformed, the height of the arc-shaped elastic piece 82 becomes higher, and the connecting block 83 at the bottom of the arc-shaped elastic piece 82 slides along the slide rod 84, thereby allowing the positioning rod 85 to be pulled out from the first through groove 11. After that, the serial line connector 7 is aligned with the serial interface 5 and connected. At the same time, the snap plate 9 is snapped into the snap groove 10, which can improve the connection between the serial line connector 7 and the serial interface 5. Stability; after the locking plate 9 is engaged with the locking groove 10, the pulling force of the pull ring 81 is released, and the pull ring 81 is prompted to move toward the fixed sleeve 6 under the action of the restoring force of the arc-shaped elastic piece 82, and the pull ring 81 drives the positioning rod 85 to engage with the first through groove 11, the second through groove 12 and the connecting groove 13, thereby further improving the stability of the serial line connector 7 and the serial interface 5, making it less likely for the serial line connector 7 and the serial interface 5 to become loose, ensuring continuous data transmission, and thus solving the problem of screen distortion on the display screen.

[0030] It is worth noting that the entire device is controlled by a master control button. Since the devices matched with the control button are commonly used devices and belong to existing mature technologies, their electrical connection relationships and specific circuit structures will not be described in detail here.
