In the construction of urban lighting and beautification, the Transparent LED Screen Display has become one of the emerging and popular LED screen display products due to its permeability, easy installation, and no steel structure required. In recent years, the beautification of the building's glass walls and the curtain walls of outdoor advertising display are also biased use it. Compared with traditional large LED screens, LED transparent screens are lighter in weight, thinner, longer service life, and more convenient to maintain. After all, the construction and beautification of cities now want more eye-catching designs. LED transparent screens can be used to add more gorgeous colors to the building without destroying the overall beautification of the building.
The higher brightness of the LED screen required the higher requirements for the LED lamp chip, and the cost is higher. The indoor environments of LED transparent screens can just use low-brightness. But if it is a semi-outdoor window LED transparent screen or LED glass curtain wall screen, then it required a high-brightness LED transparent screen.
While checking the brightness, should pay attention to whether the light of the LED lamp chip is uniform, and when observing the white light, be sure to pay attention to whether there is a color difference. The presence or absence of color difference is the most important part of distinguishing quality. The price difference of LED transparent screens lies in the quality of the lamp beads.
Many people will ignore the importance of power cables. The level of brightness depends on the size of the current. If the current is large, the wire must be thick enough so that the brightness will be high.
After the LED transparent display has been working for a period of time, touch the LED lamp with your hand to check the temperature is very high or not, it must be that the quality of the led lamp chips is not good or not. The low temperature indicates that the stability of the Led lamp chips is good.
The full solder joints prove that the soldering process is good, and the high brightness proves that the solder is used well; the more serious is the false soldering, which is prone to poor contact and troublesome follow-up maintenance. The more layers of welding, the thicker the circuit, the larger the current that can pass, and the higher the brightness of the display.
There are two ways to make transparent LED screens, one is a positive light and the other is a sidelight. Although the side-emitting light has a relatively high transmittance, the packaging technology of the lamp beads has yet to be tested by the market. The positive-emitting lamp beads are those of the traditional LED display. Aftermarket inspection, the quality is very stable.
If the positive-emitting PCB board is relatively thick, it will affect the transmittance of the LED transparent screen.
