You might imagine what is behind the faceplate of light-emitting diode windows property displays for lighting up the entire graphic poster. It is a light guide plate, the name with full spelling is light-emitting diode light guide plate, also named light-emitting diode light diffuser panel. Today we explain in detail how it operates inside backlit window displays. Before we begin, let us see the sectional view of an interactive window property display. It is composed of 5 layers similar to a sandwich.
1 The
light-emitting diode light guide's working principle
The light-emitting
diode light diffuser panel on every light-emitting diode windows display is
composed of optical standard acrylic sheet, it employs a high reflectivity and
high tech without light absorption material for laser engaging the higher light
guide point on the optical standard acrylic sheet's bottom surface of real
estate window signs. The optical standard acrylic is utilized to absorb the
light released from the light source to stay on the acrylic's surface. Whenever
the respective light-emitting diode light-guiding points are exposed to light,
the diffusion of the reflected light will take place at different angles, and
then the reflection state is wrecked out from the light guide plate's front
surface. The light guide plate can be consistently illuminated by other light
guide points of various sizes.
2 There are three
significant kinds of light-emitting diode laser guiding plates: ultraviolet
silk printing light-emitting diode laser guiding plate, laser dot light
light-emitting diode light-guiding plate, and line engraved light-emitting
diode light guiding plate.
The life of
light-emitting diode real estate window advertising displays by ultraviolet
sink printing light-emitting diode diffuser panel is around 24 months. This is
because it is ink printing irrespective of how the printing technology is
enhanced; in reality, the printing question yet exists in utilizing. The
temperature varying outside the light-emitting diode will turn it into yellow
bit by bit, then impact the image advertisement's impact at last. Thus, the
real estate light-emitting diode window display is created by laser engraving
light-emitting diode light diffusing panel or the line engraved light-diffusing
plate. The span of life will be greater, around a decade.
According to the manufacturing process, its division can be divided into three categories.
1 Ultraviolet silk
screen printing light guiding plate: simple manufacturing process, low cost,
and short service lifecycle, around 24 months
2 Laser engraving
light guiding plate: the manufacturing process is complex with a high price,
and long service life, of around a decade
3 line engraved or
wire cut light guide: The production procedure is better than the two mentioned
above, with a medium-cost and long service life of around a decade.
