Some customers report that it is very curious to see a black LED display on the market, because the display screens on the market are mostly white. In fact, this is a kind of LED display packaging technology that is different from white light. As for the specifics, what is the difference between the two? Here we have collected some information, hoping to solve everyone's doubts. Winding Wire For Submersible Motor
This products is made of solid copper wire or enamelled copper wires conductor, polyethylene insulation, polyamide jacket. It has fine performance for water-resistant, electric conducting and acid-alkali-salt resistance. It used to all types water-filled submersible motor or similar working electronics, and applied to standard of environmental-friendly.
The conductor is used the standard of GB/T395 or GB/T6109, and applied to JB/T4014 standard.
The product can be used for Voltage 380V, temperature -10℃-70℃, PH value 6.5-8.5, water pressure 1MPa, light acid-alkali-salt media or oil-media, frequency 50Hz-60Hz, for long time use with stable liability.

First, the concept
1, white light LED display
The LEDs are assembled from plastic holders and illuminating wafers. Due to the low brightness of the early illuminating wafers, engineers have made the plastic holders into a white bowl shape to enhance the focusing and reflection, so as to ensure that the wafers with low brightness achieve a brighter effect. But white light also has shortcomings. When it is black or gray, his light-emitting diode color (white) also participates in the color to be expressed on the electronic display, which produces color distortion (cannot express black, gray, dark green, etc.) ). Engineers compensate for the lack of brightness in the form of loss of color expression.
2, black light LED display
Now, when the brightness of the LED is getting larger and larger, the LED tube has no need to be white to achieve satisfactory results. In order to meet people's requirements for image fidelity, some manufacturers began to develop black LEDs to improve the contrast of LED displays.

Second, the difference between white light and black light LED display
In summary, the black light display is a display made of a plastic LED with a plastic bracket. The black light display has a higher contrast and the background color of the entire screen is more uniform.
As customers demand more and more display and LED display technology continues to advance, black LED display will become one of the mainstream products in the market, we will wait and see.
