Difference Between Transparent Display Screen Emitting Front Light and Side Light

Publish Time : Aug 01 2023

Comparison of Transparent LED Display Technologies

Transparent LED displays, using original embedded chip technology and normally emitting LED beads, have long been sought after by professional customers, and the customer groups we face are relatively high-end.

Analysis of Viewing Angles for Transparent LED Displays

Visible angle of normally emitting light: 160 degrees; visible angle of laterally emitting light: 120 degrees.

Comparison of Mixed Colors for Transparent LED Displays

The light emitted by normally emitting LED beads, after being scattered by the fog layer, has no color deviation in all angles; the refraction effect of transparent material on the light emitted by different position LED chips differs for laterally emitting LED beads, resulting in obvious color deviation when viewed from different angles.

UV Resistance of Transparent LED Displays

The anti-UV lamp housing materials of the transparent LED normally emitting fog layer can effectively prevent direct UV damage to the LED chips; UV can pass through the transparent layer of laterally emitting LED and quickly cause chip decay, accelerating the aging of the casing.

Screen Consistency of Transparent LED Displays

Differences in brightness and chromaticity exist in the whole process of LED chip production, cutting and packaging. To ensure consistency, normally emitting transparent LED requires sorting out batches of LEDs with different brightness and chromaticity from a large amount of LED lights. Only products with large output can guarantee that the LED lights used in each transparent screen come from the same batch. Laterally emitting LED just separates colors.

Comparison of Transparency for Transparent LED Displays

Normally emitting: (screen height minus strip width)/screen height> transparency for laterally emitting: (screen height minus strip thickness and LED thickness)/screen height.

Impact Resistance of Transparent LED Displays

Normal emitting can withstand 40N force on four-point plane; laterally emitting can withstand 10N force on four-point line.

Pixel Distance of Transparent LED Displays

Because of their small size, the pixel distance of normally emitting LED can be minimized; for laterally emitting LED, the width and minimum distance of the strip are.
