Features and Benefits of DLP TVs
Summary:
The world of TV technology is filled with acronyms like CRT and LCD, but DLP is becoming increasingly familiar to shoppers. DLP stands for Digital Light Processing, a technology pioneered by Texas Instruments in 1987, initially used in projectors and now in TVs.Understanding DLP Technology:
Texas Instruments remains the main producer of DLP technology, with numerous companies licensing it to build products around the TI chipset. Beyond TVs and projectors, DLP is used in unique fields like lithography and imaging.DLP technology differs from others by using a Digital Micromirror Device (DMD) to control over 1.3 million tiny mirrors, each narrower than a human hair. These mirrors tilt to reflect light and create dark and light pixels on the screen.
A color wheel spinning at 120 rotations per second filters the light, producing over 1024 shades of gray. This smooth color gradation makes DLP standout, achieved via color filters illuminated by precisely intense white light.
Key Components of DLP:
1. DMD Chip: Manages mirror movements.2. Color Wheel: Filters colors.
3. Light Source: Illuminates the system.
4. Optics: Directs the light for image projection.
DLP technology is gaining popularity in rear projection TVs, with over two million units sold. More than 50 manufacturers offer DLP models, which captured a 10% market share by 2004. Additionally, smaller front projectors have become essential in business presentations and home theaters.
Advantages of DLP Technology:
- Smooth and Jitter-Free Images: Offers seamless visuals.- No Screen Burn-In: A notable durability advantage.
- High Contrast and Color Depth: Impressive visual quality.
- Compact Design: Lighter and thinner than traditional CRT TVs.
Another benefit of DLP technology is its replaceable light source, potentially offering a longer lifespan than CRT or plasma screens. The light source is easier to replace compared to LCD models, with many user-friendly options available. New LED light sources introduced in 2006 can last up to 20,000 hours.
Disadvantages of DLP Technology:
While there are many advantages, potential buyers should be aware of some drawbacks:- Rainbow Effect: In single-chip designs, this affects color perception.
- Thickness: Not as slim as LCD or plasma displays, even if similarly weighted.
- Noise: Some models have noisy fans.
- Costly Replacement Bulbs: Prices can range from $200 to $500.
Competing Technologies:
DLP's main competitor in rear projection TVs is LCoS (Liquid Crystal on Silicon), which uses a stationary mirror and a liquid crystal matrix for image creation. As these technologies evolve, careful research and review reading are crucial before purchasing.Shopping Tips for DLP TVs:
When buying a DLP TV, understanding the technology and comparing prices is essential. Consider the type of tuner used, as many TVs now handle multiple systems like NTSC, PAL, and SECAM. This feature is vital if you need versatility across formats.Also, examine the connectivity options. Modern TVs usually support signals from cable, satellite, DVD players, VCRs, and even computers. VGA or DVI connections can enable use as a computer monitor, but be cautious with rear projection models due to potential resolution limitations.
Despite recent price drops, DLP TVs are still significant investments. Thorough research ensures not just the best price, but also the best value for your money.
