main features
Module standardized size design adopts customized irregular PCB, low current, low heat, high contrast 5000:1, high brightness and high gray, refresh ≥ 1920hz, 12-16bit gray level, and the image presents no delay and no dragging phenomenon;
It is suitable for flexible display of stage background, exhibition hall, indoor conference room, etc., which helps to improve the environment and create a special visual atmosphere;
The box structure adopts high-strength sheet metal sandblasting iron box (plate thickness 2.0), with unique segmented splicing process, which effectively reduces the splicing gap of the screen body;
The module adopts strong magnetic adsorption type installation, which can be slightly adjusted, and the flatness of the screen is good. Power box front maintenance design, special scene, can realize the front installation, with specific tools to meet the front maintenance;
The PCB board adopts flexible board, and the mask / bottom shell adopts superior silica gel material;
The thickness of the module is only 8.6 mm, with ultra-thin design and small space occupation;
Process introduction
The PCB adopts Shengyi PCB, gold deposition process, s1000-2-based materials, special circuit layout, multi-layer board process design, and high-order materials to greatly reduce the "color temperature" phenomenon;
The whole series adopts high contrast black light. When the screen is black, the ink color and luminous angle of the whole screen are consistent. When playing high-definition video, the picture is delicate and soft, and the visual effect is good.
The bottom shell is made of superior silica gel, with good flexibility, high temperature resistance, low temperature resistance, static elimination and strong protection performance;
The PCB board uses copper column welding and back glue to form a lockable base with the bottom shell, which makes the module more firm and reliable;
The single board is equipped with 18 strong magnetic magnets, each with a magnetic content of 2000 GS, which greatly solves the problems of common module degumming and warping, and effectively improves the flatness and use effect of the screen.
Precautions for installation and use
When installing and disassembling the module, it is strictly forbidden to tear the module violently, so as to avoid breaking the copper column with excessive force and damaging the PCB board;
The bending angle of the soft module is between 150 ° and 180 ° and it is strictly forbidden to fold the module repeatedly.
The installation of galvanized square pipe is not recommended, and the flatness of galvanized square pipe cannot be guaranteed. It is suggested that the sheet metal sandblasting iron box with easy installation and good flatness should be used for installation;
Static protection: LED lamp beads and CMOS tubes are relatively sensitive to static electricity, and are easy to be damaged by static electricity. When installing or maintaining the screen, operators need to wear anti-static gloves or bracelets. When operating on the worktable, it is required that the worktable must be covered with thermal antistatic skin, and the worktable and soldering iron and other equipment must be grounded;
The main body and shell of the display screen shall be well grounded, and the grounding resistance shall be less than 3 Ω, so as to achieve the purpose of lightning protection and effectively prevent the occurrence of accidental electric shock, and the installation environment shall avoid strong electromagnetic equipment;

For the configuration and connection of cable, please refer to the maximum power consumption in the actual use of the screen, and follow the professional electrician's advice, correctly connect the power supply, do not carry too much load, resulting in excessive load, and module brightness loss due to voltage attenuation. If it is serious, it will cause frequent tripping and even screen burning;
After the assembly of the display screen body, be sure to use a multimeter to check whether the 220 V AC circuit and each part of the 5 V DC circuit are short circuited, and power on the display screen after confirming that there is no abnormality;
After power on, if abnormal phenomena such as short circuit, trip and wire burning are found, it is not allowed to conduct power on test repeatedly, and circuit problems should be checked in time;
After power on, if several lines of LED display screen are highlighted, the main power should be turned off in time, and the power line and cable of the module should be checked to see if they are in good contact (if the power is not turned off in time, it is easy to cause IC damage);
Switching sequence of LED flexible screen: when the screen is on, turn on the computer first, and then turn on the LED display power; when the screen is off, turn off the LED display power first, and then turn off the computer. Incorrect switching sequence may cause led chip damage;
Try to use the dark computer desktop background to avoid the sudden impact of large current when the LED display screen is turned on and suddenly enters the bright white display state. During the work, the screen should not freeze in some bright pictures for a long time, resulting in a sharp rise in the screen temperature. These behaviors will affect the service life of IC and LED lamp beads;
The LED display screen shall not be in power off state for a long time. Long time power-off state may cause adverse chemical changes in the internal substances of electronic components (such as electrolyte, etc.) and affect the service life of components. It should keep the screen on for at least 2 hours every week;
The LED display screen should not be used in a seriously humid environment. The relative humidity of the environment should be controlled in the range of 20% - 80%. The humidity above 90% RH may have adverse effects on the switching power supply and connecting devices of the screen. If the environment is inevitably wet for a long time (return to South sky, etc.), the correct treatment method is as follows: reduce the brightness of the screen to about 60% in advance Right, slowly increase the brightness in different periods, at least after lighting for more than 2 hours, the normal brightness can be restored to play the video. When the air humidity is less than 60% RH, it is recommended to turn on the screen at least once a week for more than 2 hours; when the air humidity is between 60% RH and 80% RH, it is required to turn on the power for more than 2 hours every day to eliminate the moisture in the screen through the heat generation of the screen itself (the best time is between 7:00 a.m. and 10:00 p.m. or between 6:00 p.m. and 10:00 p.m.); when the air humidity is more than 80% RH or in the humid weather, it is required to turn on the power every day for more than 2 Play the video for more than 8 hours every day to keep the inside of the screen dry.
