Video Technology Review

This technology review will help you understand the different ways of bringing images to life. However it will not tell you which type is the “best”. Harmony Interiors will help evaluate your particular needs and see which one fits your application.

DILA

Direct-drive Image Light Amplifier

The absolute best of the display products. Most famous for their film-like quality front projectors, it is the preferred technology for filmmakers.

D-ILA utilizes a highly sophisticated form of 3-chip, vertically oriented LCOS (liquid crystal on silicon) technology that adds an inorganic alignment layer which both stabilizes the device performance and maximizes chip production. The result is superior resolution, grayscaling, brightness, and color reproduction when compared not only to LCD and DMD (aka DLP™), but also to other existing LCOS systems.

Pros:
Excellent Color Fidelity
Rich black and great contrast ratio

Cons:
Must have a controlled light environment

DLP

Digital Light Processing

DLP TV technology is a revolutionary display solution for video projectors that uses an optical semiconductor to manipulate light digitally. It’s also a proven and dependable technology preferred by leading electronics manufacturers worldwide, with more than 1 million systems shipped since 1996.

DLP TV technology was a breakthrough in eliminating the “screen door” effect of the original LCD projectors.

Pros:
Great price for performance value

Cons:
Must have a controlled light environment
Not as smooth as DILA

Plasma

Big, bright, the breakthrough product for thin televisions. They changed the size and shape of television but are now being phased out by many manufactures. The high end models still have the best picture in flat displays but new many are now subpar.

Pros:
Thin and wall-mountable
Screen can be very large
High brightness and contrast

Cons:
Heavy
Burn-in of static images a concern
May need to buy a separate sound system and TV tuner
Cheaper models have short life span

LCD

Liquid Crystal Display

Used in both front projection and in super-thin TVs, LCD projectors are bright and very affordable. There quality has evolved to compete and surpass Plasma TVs. They were once limited in size, but now all are available over 42″. Contrast ratio and pixilation problems have now been resolved. It is a mature product.

Pros:
Thin and light
Can be easily wall-mounted
No burn-in of static images
Some can double as a computer display
Available in bright versions for projectors

Cons:
Some cheaper models can dim as you angle away from the center of the screen.

LED

Light Emitting Diode

A significant benefit of LED displays over traditional liquid crystal displays (LCDs) is that LEDs do not require a backlight to function. Thus they draw far less power and when powered from a battery, can operate longer on the same charge. Because there is no need to distribute the backlight, an LED display can also be much thinner than an LCD panel. LED-based display devices also can be more effectively manufactured than LCDs and plasma displays.

Pros:
Lighter – thinner
Very energy efficient

Cons:
*EDIT* Not as smooth as DILA *EDIT*

CRT

Cathode Ray Tube

The “old standard”. You know, the one we grew up with! In fact, many are still working. Built for the long haul, these are small screens, but big boxes started it all.

Pros:
Real simulated woodgrain
Can now get 2 for $10 at Goodwill
Unlikely to get stolen

Cons:
Bulky and heavy
Lower resolution
