Description

Technical Field

[0001] This utility model relates to the field of LCD splicing screen technology, specifically to an LCD splicing screen with infrared touch function. Background Technology

[0002] LCD video walls can be used as individual displays or combined into ultra-large screens. They offer versatile large-screen functionality, adaptable to various needs: single-screen split display, single-screen independent display, and arbitrary combination display; support for digital signal roaming, scaling, stretching, and cross-screen display; setting and running various display presets; and real-time processing of full HD signals.

[0003] A search revealed that patent application number 202221677840.8 discloses a liquid crystal video wall with infrared touch functionality, comprising a liquid crystal screen and a mounting box. The mounting box is disposed on one side of the liquid crystal screen, and an infrared touch frame is provided on one side of the liquid crystal screen. Mounting plates are mounted on both ends of one side of the liquid crystal screen, and each mounting plate has a through groove on its side. Side plates slide on both ends of the mounting box near the liquid crystal screen, and rectangular blocks that fit the grooves are fixed on the opposite sides of the two side plates. A fan is installed at the top center of the mounting box near the liquid crystal screen, and a synchronous movement mechanism for synchronously moving the two side plates is provided inside the mounting box. A support mechanism for supporting the liquid crystal screen is provided between the mounting box and the liquid crystal screen. This utility model does not obstruct the liquid crystal screen after fixing and does not affect its normal use. In addition, the fan can effectively dissipate heat from the liquid crystal screen, thereby improving the performance of the device.

[0004] The aforementioned application documents achieve the corresponding installation through the installation box, but the structure is complex, occupies a large space, has low overall practicality, and requires manual adjustment for subsequent angle adjustments, making it less practical.

[0005] Therefore, we propose a liquid crystal video wall with infrared touch functionality. Utility Model Content

[0013] The ribs further ensure the rigidity of the support structure.

[0014] As a preferred embodiment of this utility model, the card slot is an arc-shaped slot, and the end clip is an arc-shaped clip adapted to the specifications of the card slot;

[0015] The design of the slot and end card shape facilitates the installation of the LCD splicing screen onto the slot at the top of the end column via the end card on the receiving mechanism, ensuring the installation and positioning effect.

[0016] As a preferred embodiment of this utility model, the mounting bracket includes a mounting plate and triangular brackets on its two front walls. The micro motor is fixedly mounted on the outer wall of the right triangular bracket, and mounting holes with opposite positions are provided on the four corners of the mounting plate.

[0020] This utility model provides a liquid crystal video wall with infrared touch control. It has the following advantages:

[0021] This LCD video wall with infrared touch control can be fixedly installed on a wall using a mounting bracket structure. With the help of the various structures on the bracket, a micro motor drives the driven shaft to rotate slowly, thereby driving the mounting and receiving mechanisms at both ends and the LCD video wall to make fine-tuning adjustments to the angle. This achieves fully automatic fine-tuning of the tilt angle of the LCD video wall. At the same time, the mounting and limiting operation is simple, and installation can be achieved by simply placing it in the bracket. This solves the problems of cumbersome manual angle adjustment and low installation efficiency in the past. Attached Figure Description
