Consultants, architects, integrators, and end users must establish their priorities when buying a led wall tiles. What are the critical factors that will enter making that decision: price, components, and length of warranty; percentage of free spare parts; reputation of supplier for references?
“Common Cathode”, refers to the common cathode power supply, in fact, is a led display energy-saving technology, refers to the use of common cathode way to power the led display, that is, the use of led beads R, G, B (red, green, blue) to separate the power supply, accurate respectively for R, G, B beads to allocate current voltage, due to R, G, B (red, green, blue). G, B (red, green, blue) lamp beads required by the best working voltage and current is not the same, so that the current will first go through the lamp beads and then to the IC cathode, the forward voltage drop will be reduced, the on-state internal resistance will become smaller.
Refresh rate is the number of times the electron beam is repeatedly scanned to the image on the screen. The higher the refresh rate, the better the stability of the displayed image (screen). The display monitor refresh rate will directly determine the price, but because the refresh rate and resolution of both constraints, so only in high resolution to achieve a high refresh rate so that the monitor can be called its excellent performance.
Foshan Nationstar is a national key high-tech enterprise specializing in the R&D, production, and sales of led and led application products. Company started its business in led packaging in 1976 and is one of the earliest led manufacturers in China.
The rising trends towards interactive media have led to the increasing demand for outdoor led billboard, driving market growth and creating opportunities for led screens. Innovative led billboard technology has spread widely due to the availability of superior brightness and longer shelf life of leds over lcd displays.
The led display system is composed of three parts: the main control circuit, the data distribution circuit, and the led drive circuit. The host control circuit generates the corresponding control signal, and stores the display data from the computer display card in the frame memory, and then transmits the display data to the data distribution circuit.
