The rear glass window in a vehicle.
A light integrated into the PDA to make viewing information in the dark possible.
A feature employed by many remote controls which illuminates the LCD screen or keypad for use in the dark. The two most common types of backlighting include LED and electroluminescent (EL). Remotes backlit with LEDs are typically bright but uneven with a yellow or green color, while EL panels are smooth with blue, white or green shades. Some EL panels feature various brightness settings. See also: keypad, LCD panel, contrast, ambient light, light sensor, pickup sensor.
Optional illumination function in handheld or e-book reader displays which allows the user to read in the dark.
A light that is placed behind the display to make the display readable in poor lighting conditions.
Light source which is behind the subject - such as when you shoot towards the sun.
LCD displays do not emit light (are not emissive), so they require external light, either from ambient sources (e.g., sunlight) or a backlight behind the LCD. The light from the backlight passes through the LCD to the viewers eyes. Backlights can be LED, EL or CCFL based.
Same as rear window.
The window across the rear of any automobile, regardless of body style, or called the back window.
Light coming from upstage, behind scenery or actors, to sculpt and separate them from the background
a light that is behind the subject pointing towards the camera
Usually an LED, placed in different possible positions, to illuminate a keytop from below.
Bright light behind a subject. It often creates a silhouette effect.
is the light that project towards the camera from behind the principal subject. It may be natural or set up by the photographer to create a backlit subject.
A situation where the primary source of light in a photograph is coming from behind the main subject. The source of light may, or may not, be directly visible. This often leaves the important features "in the dark", and difficult to see clearly. Adjust the exposure accordingly to compensate.
It enables us to use the cellular phone under low light.
A light source which illuminates any transparent or translucent material from behind.
The light source for an active matrix liquid crystal display (LCD), located behind the panel. It is usually made up of several fluorescent lamps, a light guide, reflectors, and brightness enhancing films.
Light coming from behind the subject. Extra lighting may be needed to light the front of the subject if a silhouette effect is to be avoided.
Selectable on/off illumination that lights both the display and keypad on Eagle units for enhanced screen viewing when fishing at night and in low light.
The light off camera used to separate a subject from the background.
An LCD screen that has its own light source from the back of the screen, making the background brighter and characters appear sharper.
to light from behind; usually done to add distinction between the subject and the background
Light coming from behind a subject.
Backlighting is the process of placing a light behind the LCD screen to make it more readable. Backlit screens are quite helpful in both bright conditions and total darkness.
In LIQUID CRYSTAL DISPLAY s (LCDs), a lamp positioned behind a transmissive liquid LCD designed for direct viewing, as is the case for virtually all laptop-computer displays. The PIXEL s of the LCD have varying degrees of opacity, which controls how much light from the backlight reaches the viewer from each point on the screen. [ 10:2600] Contrast with FRONTLIGHT.
is a source of light from behind that light up the display. The three ways are CCFL, LED and EL. See below.
illumination from behind an LCD display; also : the source of such illumination.
The light source for a transmissive LCD. Basically, two techniques are used in transmissive LCD designs, direct lighting and side lighting. Direct-lit backlights use CCFTs (cold cathode fluorescent tubes) and a diffuser panel directly in back of the LC (liquid crystal) layer. Side-lit backlights use CCFTs and a light pipe on one or more of the edges of the display.
A light that illuminates foreground images on a flat screen monitor. This helps make images brighter and easier to see in low-light situations.
Light passed through a clear or translucent copy from behind the image in photographic reproduction.
LCD screens do not produce any light. The light source in a flat-panel display is a fluorescent light tube located at the rear of the panel. Hence its name: backlight.
The illumination for a colour LCD display. Early colour LCD used high voltage fluorescent lamps, newer LCDs now use white LEDs which are much more energy efficient.
A light built into the terminal or reader display that makes it easier to view the display in dimly lit environments.
As the word implies, this is the light source located behind the panel of an AMLCD.
See " Rear window".
Light source installed behind the LCD panel module. Typically cold cathode fluorescent lamps are used. Page Top
Light, particularly sunlight, that illuminates subject on the side opposite the camera. It can fool a camera into underexposing the subject, i.e. making it too dark. Backlight can be countered by increasing the exposure, and can produce very attractive portraits.
Refers to an optional function in which the handheld display glows from behind for easier reading in the dark.
a light source typically placed behind a liquid-crystal display (LCD); several types of backlights are used including electroluminescent (EL) backlights, LED backlights, and cold-cathode fluorescent lamps (CCFLs); EL backlights are very thin, lightweight, and provide an even light; LED backlights consume more power, but offer a longer operating life and are brighter than ELs; CCFL backlights offer low power consumption and a very bright white light.
A technique used to make LCDs easier to read.
This refers to the light in the display and beneath the keypad of phones, which makes the phone or keypad more visible in poor lighting conditions.
Light coming from behind the subject. When light from behind is the main source, the subject is said to be backlit.
(Vision Sensing) A backlight provides even, low-intensity light. It is placed behind the target and aimed directly back towards the camera. The resulting silhouette can be inspected for proper size and shape. Learn more about backlights here.
A light in the display or beneath the keypad of a phone, which makes the display or keypad more visible in poor lighting conditions.
Light coming from behind the subject. When light from behind is the main source of light, the subject is backlit.
