Answer
For its beautiful color, high brightness, and long
life.
Advanced laser-powered phosphor display
(ALPD) is a large-format display technology and
the critical technology for laser display. With
laser and luminescent material made of rare
earth, it can provide a high color gamut for laser
TVs, up to 90% of that for human eyes, which is
far higher the 62% of the LED products
performing the best in this aspect on the
market
currently. The most updated laser source
technology ALPD3.0 improves the efficiency by
the optical design and the reliability by the
structure design and material development. The
light source has a super long life span of 20,000
hours, and has been used accumulatively for
100,000 hours.
Throw ratio is the ratio of the distance from the
lens to the screen to the screen width.
The smaller the ratio is, the larger screen it can
be with a same distance. For example, for a
100''
SD image, a ratio of 0.233 needs a distance of
516mm between the lens and the screen, when
a
1.00 ratio needs 2215mm.
A projector with a throw ratio lower than 0.3
can
be regarded as an ultra-short throw one.
A screen is not a must. The projector can be
used
for any flat surface. For better performance,
please apply to a flat wall with only one color,
and a white wall is preferred. Also, using a
recommended screen can provide the best
experience.
Make sure the sensor is not blocked and the
function is active in settings.
1) Make sure the remote is loaded with
batteries
energized;
2) On the Bluetooth setting interface, check
whether the remote is connected; otherwise,
connect it again.
1) It may be of invalid format that the projector
does not support.
