so – a beautiful image...but does it really matter?
The quick answer is yes.
This entire chart (named “CIE 1931”)
represents all of the colors visible to
the human eye. No monitor,
television or projector is yet capable
of recreating all the colors of this
spectrum.
Each display forms a triangle based
on the best “red”, “blue” and “green”
color it can produce from the
spectrum. It can then reproduce any
color within that triangle. Popular
5.6-inch LCD field monitors from
TVLogic, Marshall, iKan and SmallHD
represent a very limited range of the
spectrum (pictured).
The AC7’s OLED color gamut
(pictured) represents a massive
increase in displayed color, resulting
in immediately evident clarity and
accuracy in color reproduction.
Simply put, red tones are more “red”
looking—the same is true for blue
and green tones as well.
so – a beautiful image...but does it really matter?
The quick answer is yes.
When monitoring a high-gamut image on a low-gamut monitor (ie. any current LCD on-camera field
monitor), you are effectively unable to see the true colors that are being captured.
OLED shows you colors that LCDs cannot – meaning you are seeing more of
your image than before.
Like how a high-end set of headphones allows you to hear much ‘further’ into audio by reproducing
more sound frequencies, SmallHD OLED screens let you see much ‘further’ into your true image by
reproducing more wavelengths of light (as opposed to exaggerating it).

Unlike LCD, OLED pixels are like tiny red, blue, and green light bulbs. When they are all turned “off” (to represent “black”), they are
literally producing no light. This is unlike LCD displays which try to “block” light (produced by a backlight) that is always trying to
shine through. That’s why LCDs produce a glow even when attempting to show a completely “black” screen.
Above: Each OLED pixel consists of a red, blue and green LED which create white to the human eye when combined, and turn completely off when black. A literal absence of light makes for super-rich dark tones.
Above: LCD panels achieve colors by placing color filters (similar to lighting gels) over white backlight panels, meaning less efficiency and difficulty achieving pure black.

Above: Simulation of the difference in black level from the AC7 OLED to a traditional LCD.
A display’s contrast ratio is measured by a ratio of how bright a white pixel is compared to how bright a “black” pixel is.
Because OLED’s black pixels are literally off, the contrast ratio is virtually infinity-to-one.

A happy side-effect of such a high contrast ratio is a much higher perceived brightness. The reason for this is that the eye becomes accustomed to such vivid dark values that the bright ones appear extremely bright.
Bit Depth Defined — Color Depth or “Bit Depth” determines how many increments of value (lightness) there are between the
brightest and darkest shades of red, green and blue. Bit depth, unlike color gamut, has nothing to do with how “vivid” the display is.
6-bit panels reproduce 64 levels of color per “channel” (or color). These numbers multiply together to reach the total number of
colors the panel can reproduce. 64x64x64 = 262,144. 8-bit panels have four times the amount of R,G,B shades as 6-bit meaning 256
colors per channel. This means an 8-bit panel achieves 16,777,216 colors — 64 times more colors than a 6-bit panel.
Both the AC7 LCD and OLED panels are 8-bit, meaning they can display16,777,216 actual, measurable colors.
so... what does this actually mean to you?smooth, accurate gradients. here are some to look at.
8-Bit Gradient (256 levels of grey)
This image is an accurate representation of how the AC7 LCD or OLED will display a gradient (unless viewing this page on a 6-bit panel).
8-Bit Photo (256 levels of R, G and B)
This image is an accurate representation of how the AC7 LCD or OLED will display a photo with a natural gradient (unless viewing this page on a 6-bit panel).
6-Bit Gradient (64 levels of grey)
This image represents what the 8-bit gradient (top) looks like when shown on a 6-bit panel that does not have dithering enabled. Note the distinct lines between each shade of grey.
6-Bit Photo (64 levels of R, G and B)
This image represents what the 8-bit photo (top) looks like when shown on a 6-bit panel that does not have dithering enabled. Notice the distinct color banding throughout.
Dithering essentially paints a very fine amount of noise across the entire image which breaks up the banding that would otherwise be very apparent.
6-Bit Gradient (Dithering applied) (64 levels of grey)
This image still only contains 64 levels of grey but with a minor amount of noise applied to the gradient, the banding disappears.
6-Bit Photo (Dithering applied) (64 levels of R, G and B)
This image still only draws from 64 levels of red, green and blue but with a minor amount of noise applied to the entire image, the banding disappears.
A field monitor by nature is meant to be a device that gives you an accurate indication of what the camera is seeing so that there are no surprises when viewing the footage in post-production. This is where the term “confidence monitor” comes from.
Even though a dithered 6-bit image does quite a good job of smoothing out the banding, it still is innately a less-accurate image than what an 8-bit panel can produce, simply because...
6-bit is still only displayingWhile we agree that would be nice, 10-bit panels today are very expensive, bulky and typically reserved for professional color-grading applications. Right now the cost/benefit ratio for a 10-bit field monitor does not make sense to us, but somewhere down the line the industry will see improvement in this area and when it does we will move with it.
This only indicates the hardware driving the panel is capable of 10-bit. NOT that the actual panel is 10-bit. The AC7 has 10-bit panel drive with an 8-bit panel. Which is why we say “8-bit panel” on our marketing materials.
Monitors do not exist in bit-depths this high. These numbers come from multiplying the panel’s native bit-depth by 3 (6bit x 3 = “18bit”). While R, G and B may each contain 6 bits, this does not mean these numbers are simply added together to get the panel’s true bit depth.
Currently, the only available panel in the world that is 5.6 inches and 1280x800 resolution is the one SmallHD first used in the DP6—we know it is a 6-bit panel. One company has claimed it is 8-bit, 16 million colors on their website. This is not true. We’d rather not say this company’s name, we only intend to clarify the matter so that people can make decisions based on facts.

Staying true to the idea of a “confidence monitor,” a large portion of the accuracy of an image is down to its resolution, which is what brought us to start this company to begin with. The AC7 LCD and OLED screens are both HD at 1280x800, providing the ultimate tool for achieving critical focus and accurate exposure.
No constantly burning backlight means lower power usage for OLED technology. AC7-OLED models only draw 10 watts—an amazing reduction in power consumption over other display technologies featuring a similar color gamut – even including competing OLED monitors.
