	Display backlighting system - Patent 6347882
		The display backlighting system of claim 8, wherein the display surface area of the liquid crystal display is parallel to a mounting surface area of the printed circuit board.
		Typically, the goal of backlighting is to route light from a source efficiently and evenly into the planer area (backplane) of a light pipe directly behind the LCD so that it may escape forward through the LCD, giving the appearance of an illuminated display.
		Backlighting requires that light from the light source be emitted into an entrance lens of the light pipe and distributed evenly within the light pipe.

	LCD Backlighting
		The advantages of LED backlighting are its low cost, long life, immunity to vibration, low operational voltage, and precise control over its intensity.
		LED backlights come in a variety of colors, with yellow-green being the most common, and now white is becoming cost effective and very popular.
		LED backlights on LCD modules are generally driven with a dc voltage through a current limiting resistor.

	Creating backlighting in your studio shots
		If you are backlighting your subject you will usually get better results, with less risk of flare, if you avoid using zoom lenses.
		Probably most commercial photographers have a 3'x'3' or larger softbox suspended from the ceiling or fitted to a boom arm, this is usually used slightly behind the subject and angled forward to produce a degree of backlighting as well as toplighting, and this is a good starting point for many subjects.
		Larger softboxes may be needed too, because even a softbox placed as close as humanly possible to the subject needs to be a minimum of three times the subject size if diffused specular highlights are required.

		However, once mastered there is little doubt that backlighting can be magical and will add both drama and visual impact to your photographs and diversity and interest to your portfolio.
		Backlighting will enhance mist, rain and haze adding creativity and atmosphere to landscape images.
		Overexposure is a common problem in backlighting, as the brightly-lit background will overly influence the camera's meter; this will turn the subject very dark, indeed almost silhouette like.

	PhotoNotes.org Dictionary - Backlighting
		Backlighting is particularly difficult for automatic exposure systems in cameras to deal with, since the range of light tends to be so extreme and lenses tend to flare.
		Backlighting can also be a deliberate technique for dramatic effect (a backlit subject with no lighting from the front becomes a silhouette) or to separate the subject from the background.
		Backlighting pushbuttons are commonly indicated on cameras by a backlight icon.

	Compositing Backlighting - Page 1 - General Rendering / Lighting for Maya
		As you can see in the Photoshop layer palette, there is a background, the subject that will be exposed to the glowing backlight, and the first layer that will soon provide the backlight effect that occurs when film is overexposed to light when the subject is in a much dimmer light (in the foreground).
		This technique is pretty much analogous to the way I used to give backlight glows in Toonz (which had NO effects except blurs, level adjustments, color adjustments, and an add function) for digital cel animation production.
		Some things to keep in mind at the lighting before rendering is to have a light from behind the subject since it would be strange to have a backglow when the subject isn't lit from behind at all.

	Backlighting Basics
		When a subject is translucent or semi-translucent, like many jellyfish, comb jellies and salps, backlighting can be effective, especially when the lighting reveals the details of internal organs and other structures.
		Despite the term “backlighting,” it is almost never a good technique to position a strobe directly behind a subject in a direct line with the lens.
		When backlighting with a strobe, I set the strobe in a manual mode and expose a series of frames with my strobe-to-subject distance changing from six inches to one foot to two feet to three feet, and sometimes slightly farther.

	LED-LCD-CCFLs-backlights
		The adoption of LED backlights in these applications promises to reduce the power consumed by backlighting (in the long run, if not always in the near-term LED backlight solutions.) At the same time, LED backlights should alter the backlight’s power supply requirements.
		For backlight systems using smaller chips, Cree has increased the brightness of its green XThin LED chips from 8 mW to 10 mW, for the top radiant flux bins, to better match the high brightness of the company’s blue XT-21 and XT-24 chips.
		The replacement of CCFL backlights with LED backlights is likely to impact the backlight power supply design as it will alter voltage and current requirements for the supply.

		Non-uniform backlighting is usually visible on a fl screen with dim external lighting (this is due to non-linear sensitivity of the human eye), but here you can notice it even on a light background and under bright external light.
		Its irregular backlighting and bad color rendition are no good for work, while its poor response time is going to spoil the picture in dynamic games.

	Design Challenges for Backlighting LCD TVs - Maxim/Dallas
		Also, in some LCD-TV applications, it is necessary to synchronize the slow burst-dimming frequency of the CCFLs to the vertical sync rate to improve the image response of the LCD panel.
		These devices can be configured to drive one lamp per channel (Figure 9), or multiple lamps per channel (Figure 10), which allows the user to adapt the design to meet their cost vs. performance target.
		Although there is a light diffuser placed between the CCFL lamps and the LCD panel to help evenly distribute the backlighting, uneven lamp brightness can still be visible and detract from the quality of the TV image.
