Description
Technical Field
The invention relates to the technical field of LED display screens, in particular to an LED display screen with a front-back maintenance mechanism of a module.
Background
The LED display screen is a flat-panel display, which is composed of a plurality of LED module panels which are spliced to display various information such as characters, images, video and video signals, and the like, and is a diode which is made of compounds of gallium, arsenic, phosphorus, nitrogen and indium by controlling the display mode of a semiconductor light-emitting diode, and can radiate visible light when electrons are combined with holes, so that the LED display screen can be used for manufacturing the light-emitting diode, is used as an indicator lamp in a circuit and an instrument, or is used for forming a character or digital display, and comprises a gallium arsenide diode Guan Fa red light, a gallium phosphide diode Guan Fa green light, a silicon carbide diode yellow light-emitting diode and an indium gallium nitride diode blue light-emitting diode.
At present, the use of the LED display screen is more and more widespread, and because the LED display screen is limited by the installation environment and the use occasions, a plurality of LED display screens need to be maintained front and back, and the LED display screens maintained front and back are formed by splicing modules, so that the modules are required to be capable of supporting the front and back maintenance.
With the progress of technology, the front-back maintenance mode of the LED display screen module is developed from the earliest maintenance mode of a flip cover and a box taking mode to the currently commonly used twist lock type maintenance (the module is sucked through a magnet and is taken through an air suction tool during maintenance) and magnetic suction type maintenance (the module is taken through a small hole on the front side of the module by inserting a pressing lock behind a hexagonal wrench operation module). For both maintenance modes, a certain limitation exists, the twist lock type is not too small because the twist lock needs to be operated with larger force to be locked, the basic strength of the wrench needs to be met, the limit wrench is 2.5mm in opposite side distance, the wrench is too small to fail, so that the wrench can be inserted only by opening a hole larger than 3.0mm in front of the module, the twist lock type is only applicable to an LED display screen with more than P5mm in point distance, the lamp bead size of the current minimum outdoor LED display screen is 1.5mm by 1.5mm, the usable minimum distance is P4.8mm, the limit wrench cannot be used for the lamp bead with the distance of less than P4.8mm, and the price of the LED lamp bead with the size of 1.5mm is higher than that of the conventional LED lamp bead. The magnet attraction is used for attracting through a magnet, the module is taken through an air suction tool during maintenance, the attraction force of the air suction tool is not large, and can only reach about 5KG, so that the magnet attraction needs to be controlled within 5KG, the situation of small attraction force can only be suitable for the working environment of indoor vertical installation or no vibration of users, the magnet attraction is small in safety coefficient and easy to fall off under the environment of outdoor (wind sand, rain flushing force and the like) vibration (such as a high-speed rail station and the like) or the environment of non-vertical installation of a screen body (such as a backdrop on, the screen body is on the top), accidents are easy to occur, the front and back maintenance cannot be realized for some working environments which cannot be used for twist lock maintenance and magnetic attraction maintenance, the point spacing with the largest using amount of the current LED display screen is between P3mm and P5mm, and even if the situation is done, the risk coefficient is also particularly high.
Therefore, the invention provides a LED display screen with a front and rear module maintenance mechanism and a front and rear module maintenance mechanism, which is suitable for being installed with the diameter of less than P5mm to solve the problems which can not be solved by rotating lock type and magnetic attraction type.
