Background
The LED display screen module consists of an LED lamp bead, a PCB board, a driving IC chip, a plastic sleeve, a capacitor device and the like; the LED display screen module can be divided into a single-color module, a double-color module and a full-color module according to the display color; the full-color LED display screen module is generally applicable to outdoor large screens and indoor display screens.
Because indoor LED display screen module is used for watching more scene of personnel generally, so indoor personnel talk more noisy, and to outdoor LED display screen, outdoor noise is great relatively, consequently need ensure the sound transmission rate of LED display screen module, avoid the sound that LED display screen module sent less and lead to watching personnel to be difficult to hear.
In addition, the LED display screen module is formed by assembling a plurality of display screens, so that line short circuit or other problems easily occur, and the LED display screen module is triggered to catch fire, even a fire disaster is caused; based on the above, it is necessary to ensure that the LED display screen has a certain fireproof performance, so that potential safety hazards can be reduced.
However, when the common LED display screen is used in daily life, there are some problems usually, along with development of technology, a person skilled in the relevant field also optimizes the LED display screen in a large amount, so as to perform more accurate comparison, for example, chinese patent publication No. CN209471670U discloses a sound-permeable LED display screen, which comprises a display screen, wherein the display screen is formed by splicing a plurality of LED display modules, each LED display module is composed of an LED display module, a power supply assembly, an LED box and an LED receiving assembly, the LED display module is mounted on the LED box, the power supply assembly is mounted on the rear surface of the LED box, and the LED display module is provided with a printed board and a plurality of sound-permeable holes; the LED box is a box with large holes, the large holes on the LED box are the supporting, installing and sound-transmitting integrated holes of the LED display module or the large holes are formed in the LED box, and the edges of the LED box are provided with small sound-transmitting holes.
When the display device is used, the arrangement mode of the luminous pixels is changed, so that the area of the sound transmission holes is greatly increased, the space between the luminous pixels is fully utilized to set the sound transmission holes, the good sound transmission requirement is achieved, the wiring of the luminous pixels is not influenced, and the display device has good sound transmission rate and good display function.
However, the LED display screen has some disadvantages in the practical use process:
1. because be equipped with the sound hole on the LED display module, therefore the one side that the LED display module sound hole was close to the LED box is used for gathering sound and is followed the sound hole and is kept away from one side transmission of LED box and go out, from this, although can realize the effect of sound through the sound hole, but the sound hole is the straight hole, consequently only can gather the sound within its aperture scope, there is the limitation when leading to the sound hole to gather sound, and the sound hole can only normally transmit the sound to openly, and can't form the public address, and then lead to the sound volume of transmission less, can't be adapted to noisy environment.
2. Because the LED display screen is easy to cause short circuit and other problems in the use process, and then fire disaster is easy to occur, the prior art does not relate to the fireproof performance of the LED display screen, once a fire condition occurs, the fire condition cannot be controlled in time, so that potential safety hazards exist, and the personal safety of watching staff is influenced.
3. Besides, the display screen is formed by splicing a plurality of LED display modules, the LED display modules are vertically arranged in the normal use process, and the LED display modules which are spliced in the prior art cannot be limited and fixed, so that the LED display modules are easy to incline under the action of gravity, normal use of the LED display modules is affected, the LED display modules are easy to drop and damage, and the cost is affected.
