Blacks on the Note 3's display look stunning, as the display is physically off when black needs to be displayed due to the
lack of a backlight in the panel's construction.
The keys have ample spacing and make a satisfying click while you type, and there are three
levels of backlight for when you're working in the dark.
I live alone, so reading all night with a light on is not a big concern, but I am excited at the idea
of the backlight in the app.
Then, the
function of backlight began to appear from many manufacturers and technology of production of them was not different from Kindle or Nook.
Normally, this is where we'd criticize the lack
of backlighting for the remote, but with so few controls available, easily learned touch memory makes backlighting unnecessary.
I found the Nookcolor quite comfortable to read on, partly because it's easy to adjust the
brightness of the backlight for pretty much any reading environment.
A new layer of light - modulating cells will «permit pixel - by - pixel
control of backlight intensity.»
While both styles have their pros and cons, full array displays with local dimming (i.e. the ability to turn off specific
zones of backlights at a time) are often preferred by videophiles for their ability to render richer contrast between the lightest and darkest images on screen.
All three readers feature their own version
of backlighting technology, and claim battery life of up to eight weeks, though your mileage may vary depending on your usage pattern.
We can now clearly see the smooth integration of the rear wing into the Panamera's sloping rear hatch and the spoiler that lifts and extends outward from the
base of the backlight glass.
In fact, the number
of Backlight LEDs has roughly doubled (from 36 to an estimated 72 to 82), so the Backlight power has approximately doubled.
On the other hand, the higher Pixels Per Inch lowers the Display Power Efficiency because at higher densities the LCD Backplane circuitry proportionally blocks
more of the Backlight.
While I have no qualms with capacitive buttons myself - in fact I sometimes prefer them - the lack
of backlighting of the back, home and menu buttons can be incredibly frustrating until you've properly learnt the order in which they are arranged.
Unless you have an OLED screen, you're always going to have some
form of backlight which limits the potential contrast; you're stuck with either white on varying degrees of not - quite - dark or gray on almost - black.
The 384 backlight zones are no joke on this monitor if you compare that to the
number of backlight zones in the expensive flagship TVs.
So therefore, you better hope you're not in the dark when trying to turn on the backlight... because hoping you're touching the Settings bar at the top, and then HOPING you're in the right
area of the Backlight bar from there is a joke.
Blacks are truly black with vary a hint
of backlight leakage from the brilliant white portions of the display.
Some owners are reporting an unacceptable level
of backlight bleed, with bright patches appearing at the edges or corners of the display.
Most importantly, eliminating the power demands
of the backlighting needed by conventional LCD displays means that e-paper displays draw negligible power.
Thanks to the IPS panel, the image remains viewable at extremely wide angles, but the luminescence
of the backlight becomes very obvious in angled viewing.
The power consumed by LCD displays is independent of the brightness and color distribution of the images — it only depends on the Brightness
setting of the backlight that illuminates the LCD from behind.
The spectra of an LCD display is just the
spectrum of the backlight filtered through the individual Red, Green and Blue sub-pixel filters within the panel.
Local dimming is a technique that dims
parts of the backlight where it's not necessary and divides it in several zones.
Seeing the brightest highlights of HDR footage able to appear just a pixel away from inky blacks without a
hint of backlight clouding or compromise in the intensity of the bright areas is an immersive OLED trick that never gets old.
OLED used to rule this category but quantum dots, by improving the
purity of the backlight, have allowed LED / LCD TVs to surge forward in color accuracy, color brightness, and color volume, putting them on par with OLED TVs.
However, delivering so much brightness from an edge LED lighting system does mean that the Q7F can't deliver black levels as deep and free
of backlighting clouding issues as Sony's 65XF9005 / 65X900F can.
In any LCD panel, the
presence of a backlight provides some measure of lighting to every single pixel, even when none is required.
The above two pictures illustrate the effect
of the backlight at maximum brightness with a 100 % black image, showing that while black levels on this LCD panel are good, they are not truly black by any stretch of the imagination.
You can also adjust the intensity
of the backlighting with simple button presses, and you can also customize what keys are backlit by picking certain keys.
Of course, this isn't an OLED display, so you'll still notice the distracting glint
of a backlight when wearing it to bed.
Knife - edge blacks and frothing whites still dominate (with the occasional scarlet splash of women's hair and lipstick), and characters often carry a fizzing
nimbus of backlighting, like dark and demented angels.
Evacuating engine - compartment air requires outlets at both sides and under the rear
edge of the backlight.
What seems to be an innovation is the
shape of the backlight, which carries a lot of transverse curvature allowing its intersection with the deck lid to reach a central point, making the upper structure resemble a teardrop in plan view.
It's not a bad looking shape on our tester's 15 - inch alloys, although the severely pinched rear end limits visibility
out of the backlight.
Up until now this has been accomplished almost exclusively by adjusting the materials and
chemistry of the backlight LEDs, OLEDs, and LCD color filters, which is a very difficult and involved process.
The funny thing here is that the
calibration of the backlight isn't so good and as such even at zero brightness, the screen is considerable clear enough for movies indoors.
The touchscreen will be
devoid of any backlight and will be as much receptive to stylus input with a digitizer as it will be to finger presses.
The main issue that Gani faced is the
hue of the backlight, which with its bluish tinge has led to many a sleepless night for him (this he claims is a scientifically proved fact), enough to cause him to act on his own accord.
The reflective display technology uses ambient light sources to display 16 gray level images, so doesn't require the
kind of backlighting used in LCD screens.
