P10 Red Color Outdoor LED Scrolling Message Sign CMAX-M5

Q: Is the TV screen good for the LCD or the LCD?: Although the cost of CCFL is not high, it is about ten yuan, but the maintenance staff will certainly open a high price to help you ), The operating voltage is lower (LED in 2V ~ 4V can work, and CCFL tube needs nearly 1200V high voltage to start, so need to use a special inverter circuit to provide high voltage. Inverter circuit is easy to bad.

Q: Led display and led lighting What is the difference?: Application areas are different. Led display mainly in: government square, leisure square, bustling business center, advertising information release card, commercial street, railway station, sports venues (UNILUMIN Universiade) and so on. Led lighting is mainly home, mall, roads and other lighting

Q: Production of LED display the basic raw materials which ah?: PCB, circuit board, drive IC, resistance, exclusion, LED light-emitting diodes, row of pins, row seats, capacitors, three anti-paint, plastic sets of plastic, waterproof plastic, fine screws, copper pillars, magnets, Power cord, connector, switching power supply, frame. Control System.

Q: What is the thickness of the led display?: Commonly used profiles are made of 9cm thickness, ultra-thin can do 5cm, the box to do more than ten centimeters have a few, on-demand custom.

Q: Led display support what video format: In fact, as long as you can play the video player, the display can be displayed! You put the display number of points set up, the video with the storm video playback, as long as the storm video to the LED display display area, the same size can be!

Q: LED display a board dark light how is it?: With a multimeter to measure whether the normal voltage of the unit board, and then measure the power module voltage output is normal, if not, then determine the power module bad.

Q: Comparison between LED display and DLP splicing: LED is a light-emitting diode, is a solid-state semiconductor devices, it can be directly into the energy of light energy.

Q: LED display more than the size of the area must be 380v: LED display itself only need low-voltage DC power supply, whether it is 380V or 220V need to go through the buck and rectifier, which is the screen does not matter. Whether it is to use 380V or 220V depends entirely on the load balance of the power grid considerations, which depends not only on the size of the display, but also on the local grid capacity. In general, LED is weak devices, even if the display area and then large, the total power is also less than where to go, so you can use 220V single-phase power supply, but the power supply cable cross-sectional area to be larger, but the power circuit Much simpler.

Q: LED display applications are what: Securities trading, financial information, airport flight dynamic information display, port, station passengers, sports venues information display, road traffic information display, dispatch command center information display.

Q: IPS screen and LED screen difference: LED is the light-emitting diode, so the so-called LED screen is the concept of confusion, in fact, LCD panel with LED as a backlight, but also useful as a backlight CCFL, CCFL is cold cathode fluorescent tube,
