- 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 power can not be displayed properly
- Make sure that all hardware, including the control system, is fully powered up. (+ 5V, do not reverse, then wrong)
- Q:Is the TV screen good for the LCD or the LCD?
- Whether it is LED TV or LCD TV, their screen itself is LCD (LCD), the real LED display is difficult to use in the field of home TV, because its pixel is too large, high-resolution case is difficult The Now many of the store's dynamic billboard is LED dot matrix screen.
- Q:What is the difference between an LED display and an LCD monitor?
- LED is Light Emitting Diode. LED applications can be divided into two categories: First, LED display; Second, LED single tube applications, including backlight LED, infrared LED and so on. Now on the LED display,
- Q:LED display power supply how to configure how many units with the plate is calculated.
- I with 14 P10, power supply * (0.8-0.9) / each unit board power can be rounded down.
- Q:LED electronic display and P have anything to do
- P generally represents the pixel pitch, and P followed by the value of the two mainly refers to the distance between the pixels, usually called the point spacing. And the smaller the value of this point spacing, the higher the unit pixel, the more clear the display screen.
- Q:How to identify the quality of led display quality
- ircuit board: circuit board manufacturers more, Shenzhen is the gathering of electronic products, procurement of raw materials this piece is very fast, the circuit board is divided into two layers and four layers of board, the thickness of two layers is 1.6. , The quality of the circuit board is the internal conductor of the circuit board, the thickness of the conductor to reach the standard thickness to 1ns or more, because the use of the display in the process of temperature rise and lower, if the conductor thin easy The use of the process of fusing, this will cause a large area of quality problems.
- Q:Production of LED display the basic raw materials which ah?
- LED display (LED panel): LED is light emitting diode, LED abbreviation, referred to as LED. It is a kind of control by the semiconductor light-emitting diode display, the approximate look is by a lot of usually red light-emitting diodes, light off the light to show the characters. Used to display text, graphics, images, animation, market, video, video signals and other information display screen.
- Q:16: 9LED What is the approximate size of the display?
- 16: 9 is only a proportional form, the specific size to be determined according to the area of the display. You display 16 meters long, 9 meters high, is 16: 9 ratio; display length of 10 meters, 5.6 meters high, is also the ratio of 16: 9. So there is no specific size!
- Q:Led display what format can be displayed
- LED display is also flexible, you can achieve: with a TV screen overlay text information, panoramic, close-up, slow motion, effects and other effects of real-time editing and playback (need to configure another non-linear editing equipment) Window display different screen and text functions • to meet the requirements of the use of theatrical performances • graphic effects display function:
