The Difference Between LED Transparent Display Positive Light-Emitting and Side Light-Emitting

1. Technology comparison of transparent LED display

LED transparent display, using the original embedded SMD technology and normal light-emitting lamp beads, the technology has long been sought after by professional customers, and the customer groups we face are relatively high-end.


2. Angular analysis of transparent LED display

Viewing angle for positive light-emitting: 160 degrees; viewing angle for side light-emitting: 120 degrees.

3. Mixing color comparison of transparent LED display

Positive light-emitting LED beads scattered light through the fogging layer, no color deviation from all angles; side light-emitting LED beads transparent material on different positions of the LED chip issued by the light refraction effect is not the same, from different angles there will be obvious color deviation phenomenon.


4. Anti-UV of transparent LED display

Transparent LED positive light-emitting atomization layer and anti-UV lamp shell material, manufactured by our China led display screen,  can effectively prevent UV light from directly harming the LED chip; LED side light-emitting UV light through the transparent layer directly to the LED chip, which will make the chip quickly decay, the shell accelerated aging.

5. The display consistency of transparent LED display

LED chips from wafer production to cutting into chips and then packaged into LEDs throughout the process, there will be differences in brightness and chromaticity, transparent LED positive light-emitting in order to ensure consistency, the need to sort out from a large number of LED lights in batches of different brightness and chromaticity, only a large number of products, to ensure that each LED transparent display used by the LED lights from the same batch. And side light-emitting is simply separate colors.


6. Transparent comparison of transparent LED display

Positive light-emitting: (Display height minus the width of the light bar) / Display height > side light-emitting transparency: (Display height minus the thickness of the light bar and LED thickness) / Display height.

7. Impact resistance of transparent LED display

Positive light-emitting four-point plane force, impact resistance of 40N; side light-emitting four-point linear force, impact resistance of 10N.

8. Pixel distance of transparent LED display

In our commercial led display screen, Positive light-emitting LED due to the small size, the spacing can be achieved at a minimum of 2.5mm; side light-emitting LED width of 3.1mm, the minimum spacing of 3.9mm.
