Simply speaking, the LED display is composed of a number of display units (unit display panels or unit display cabinets) that can be combined and spliced, together with a suitable controller (main control board or control system). Therefore, a variety of display panels (or unit cabinets) with different control technology controllers can form a variety of LED display screens to meet the needs of different environments and different display requirements. 3. Scanning control board: The function of the circuit board is data buffering, which generates various scanning signals and duty cycle gray level control signals. 5. Transmission cable: The display data generated by the main controller and various control signals are transmitted to the screen by the twisted pair cable. 6. Main controller: buffers the input RGB digital video signal, converts the gray scale, reorganizes, and generates various control signals. 7. Dedicated display card and multimedia card: In addition to the basic functions of the computer display card, it also outputs digital RGB signals and lines, fields, blanking and other signals to the main controller. In addition to the above functions, multimedia can also convert the input analog Video signal into a digital RGB signal (ie, video capture). 8, the computer and its peripherals Plate Non-damaged Desulfator with Smart Pulse, Smart Restorer with Battery Charging Ability.

First, the main components of the LED display (take the more complex synchronous full color screen as an example)
1. Metal structure frame, which functions to form an inner frame, and is equipped with various circuit boards such as display unit boards or modules, and a switching power supply.
2. Display unit: It is the main part of the LED display, which is composed of LED lights and drive circuits. The indoor screen is a unit display panel of various specifications, and the outdoor screen is a module cabinet.
4. Switching power supply: Turn 220V AC into various DC power and supply it to various circuits.

When the lead-acid battery is under using or stored status for a long time, due to factors such as undercharge, self-discharge and environmental temperature changed, its performance will gradually decline, and it might even not be used any more. The main cause of battery failure is that the lead sulfate on battery plate gradually lose activity for the above factors. The crystallization thickens and hardens, cannot be reduced to fluffy lead as recharging, as a result, the battery capacity decreases or to be completely scrapped. This phenomenon is known as [irreversible sulfation".
Battery Charger and Restorer 2-in-1 is a multiple-stage charger with smart pulse maintenance ability. It is a Battery Desulfation Charger with a Automatic battery maintainer's function. This innovative, state-of-the-art battery restorer smartly knows how to restore battery in charging process, Unlike other common chargers on the market, you don't need to select the battery type. It works smartly on any type of 12/24/36/48/60/72-Volt lead-acid battery – VRLA, AGM and Flooded. Proprietary algorithms combined with microprocessor & IC controlled technology measure the battery's voltage and current to automatically determine and deliver the precise pulse frequency and duty cycle based on the size and condition of the individual battery.
Battery Charger And Restorer 2-in-1 is more than a common pulse charger and desulfator. It is a multiple-stage pulse charger with Optimizer and Recover, During the restorative battery charging cycle, VoltaTech's patented, optimized High-frequency pulsing and smartly changeable duty cycle constantly work to minimize and reduce battery sulfation and internal resistance. By reducing the size and number of lead sulfate deposits on the battery plates- the No.1 cause of battery failures, increase capacity and release energy to keep battery in new conditions, your battery will charge deeper, maintain greater reserve capacity and last longer service lifespan– up to 2 times longer.
To reduce the charging links of the battery to be stored, after removal from various military equipment and Military backup power(UPS), the batteries can be directly connected to our smart lead-acid battery emergency support system, which can smartly enter pulse maintenance state after fully charging the battery,The tiny pulse charging current can also offset the self-discharge of battery, and ensure that the battery can be put into emergency use at any time no matter how long it is stored.
