The liquid crystal forms little shutters that polarize the light. They need another permanent polarized light filter in front that is oriented 90 degrees different. This cancels the light completely and makes the display opaque.
The Liquid crystal can be altered electrically.
Contacts inside the glass envelope are a very thin, transparent layer of silver.
The arrangement of the sliver contacts can make the segments of a number display, symbols or pixels.

What light source does an LCD use?
An LCD (Liquid Crystal Display) uses a backlight source to illuminate the screen and display images. This backlight could be a fluorescent light or LED (Light Emitting Diode) depending on the model and technology used in the LCD display.
When can light bend?
Light can bend when it passes through different mediums with varying densities, such as air and water. This bending of light is called refraction. Additionally, light can also bend in the presence of gravitational fields, a phenomenon known as gravitational lensing.
Which light ray will bend the least when red green and blue light rays enter a drop of water?
Red light rays will bend the least when entering a drop of water, as red light has the longest wavelength of the visible light spectrum. Blue light rays will bend the most, as they have the shortest wavelength. Green light rays will bend somewhere in between red and blue.
Does light bend as it passes through materials?
Yes, light can bend as it passes through materials with different optical densities, a phenomenon known as refraction. This bending of light occurs due to the change in speed of light as it transitions from one medium to another.
Does white light reflect or bend?
White light can both reflect and bend. When white light hits a smooth surface, it will reflect off the surface at the same angle it hit it. When white light passes through a different medium like glass, it will bend due to refraction.
Do rainbows bend light?
No. Water droplets bend light to make rainbows.
Will LCD Clocks light up at Night?
LCD displays require an additional light source to light up in the dark. LED displays generate their own light.
Does light bend when it reflects on glass?
no , and its not calld 'bend' its called 'reflected' but its like bend but ITS NOT :)
How does light curve at all?
Light does not bend.
What conditions will bend light?
This phenomenon is called diffraction. when light is incident on the opaque substances having width comparable to wavelength of light then light bend.
What do DLP and LCD stand for?
DLP is digital light processing and LCD is liquid crystal display.
What does light have to do with eyeglasses?
Bend it
If the refraction is large will it bend light more or less?
It will bend more.
What vdoes LCD means in LCD Projector?
LCD = Liquid Crystal DisplayHow a LCD Projector Creates The ImageTo create the image, red, blue, and green light must be shown through their respective LCD screens, then brought together in a prism to form an image. This is done with the use of mirrors. As the light propagates from the metal halide lamp, it is shown through a dichroic mirror. This mirror only lets the red light through it but reflects the rest of the light. The rest of this light goes through another dichroic mirror that only lets the blue light through but reflects the green light. Hence, the red light is shown through a mirror and reflected into its LCD screen while the green light is reflected into its LCD screen. Then, the remaining blue light that passed through the second dichroic mirror is reflected a couple times into its LCD screen. Finally, the three colors are filtered by the gray scale images on the LCD screens to form the desired image, overlapped by the prism and projected onto a screen.
