Q: What is the difference between an LED display and an LCD monitor?: Notebook LCD screen commonly used is TFT. TFT (Thin Film Transistor) refers to the thin film transistor, each of the liquid crystal pixels are integrated in the pixel behind the thin film transistor to drive, which can be high speed, high brightness, high contrast display screen information is the best One of the LCD color display devices is now the mainstream display device on laptops and desktops.

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?: LED display and lighting are LED light-emitting diodes as light source. The difference is that the application of LED: LED display using dot matrix, the combination of different colors of light-emitting diodes, through the control system, power system, signal system and other forms of control, composed of LED device array display screen; and LED Lighting is a monochrome diode excitation, the pursuit of brightness, gray and white balance.

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: How to identify the quality of led display quality: Control card is basically 99% of the led display manufacturers are outsourced, the industry is better that is the celebration, superstar, de Puda, Nova, Carter these are used in full-color display more Some, relatively stable stability is better.

Q: LED outdoor display which part of the composition: Outdoor LED display is usually in the form of outdoor media. The main forms include road LED display, LED electronic display, LED full color screen, LED screen, balloon, airship, compartment, large inflatable model.

Q: How do I choose the dot pitch of the LED display?: Installation classification: lifting, hanging, seat, inlay, rotating bracket hanging;

Q: LED display applications are what: Mail, shopping malls and other services in the field of business publicity and information display, advertising media, new products, performances and meetings, exhibitions, LED display large screen as an exhibition organizer to provide one of the important services, indoor large-screen TV applications

Q: Led display speed how to tune: When installing the LED bar screen software, enter the text that needs to be displayed in the blue edit box. After the text editing is finished, click "Frame Properties" to pop up the following dialog box to set the frame properties. Display speed 1 fastest, 16 slowest. After setting the current frame, you can point to "previous frame" or "next frame" to move to another frame. After all the parameters of the frame are set, click the "Exit" button to return to the main window.
