Contrast ratio determines the quality of a projected image. High brightness alone is not enough.
A New Standard for Mobile Projectors
High Contrast Ratio Is the Key to Crisp, Sharp Image Quality.
enabled by the DLP
where superior visibility is required for charts and small-font documents. The U4 Series offers superior contrast performance
Crisp, Sharp Image Quality: Reason
Black looks truly black.
A high-brightness but low-contrast projector displays a whitish
image with poor visibility. Visibility largely depends on how dark
black is reproduced, and is critical in projecting business and
education materials which involve heavy use of black text and
lines. Higher contrast means more visibility and ensures a crisp
image with pure black text.

Contrast ratio influences the range of
tonal gradation a projector can express.
Contrast ratio is the key factor in sharpness, a crucial quality for projectors used in business and education
TM
projection system. These PLUS projectors deliver incredibly high contrast ratio of 1500:1 and thus crisp, sharp image quality.
Crisp, Sharp Image Quality: Reason Crisp, Sharp Image Quality: Reason
Pictures appear clear and vibrant.
Because of an optical illusion called the Mach band effect, the
human eye perceives a change in brightness between two
neighboring pixels more intensely than the actual change in the
amount of light. High-contrast projectors accurately reproduce
the difference between the lightest and darkest portions of an
image, providing crisp pictures. Look at the photos below. The
photo with the black border appears sharper than the photo
with the white border, even though the photos themselves are
actually the same.
The diagram below describes
how the human eye perceives
the change in brightness
between black and white.

Charts set against photos are
delivered with excellent clarity.
Combined images of colorful charts and photos sometimes look
flat and unclear when projected, even if they look beautiful on
the computer screen. But this never happens with PLUS
projectors. Our projectors’ high-contrast ratio ensures rich tonal
gradations, allowing a chart to stand out sharply from a
background photo.
