Introduction to Projection TVs
Projection TVs have been a staple in home entertainment since the late 20th century. The basic principle behind a projection TV is simple: it uses a projector to display images onto a screen, rather than relying on a built-in display panel like traditional TVs. This setup allows for larger screen sizes without the necessity of a large, bulky TV unit, making it a favorite among those who desire an immersive viewing experience without compromising on space.
How Projection TVs Work
Understanding how projection TVs work is essential to appreciating their unique benefits and limitations. The core components of a projection TV system include a projector, a screen, and sometimes, a tuner or external device for signal reception. The projector houses the optical engine, which could be a CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), DLP (Digital Light Processing), or LCoS (Liquid Crystal on Silicon), among others. Each of these technologies has its own strengths and weaknesses, affecting the overall picture quality, brightness, and color accuracy of the projected image.
Types of Projection Technologies
- CRT Projectors: These use three CRTs (one for each primary color) to create the image. While they offer excellent color accuracy and a high contrast ratio, they are bulky and heavy.
- LCD Projectors: Utilizing LCD panels to block or allow light to pass through a matrix of pixels, these projectors are generally more compact and lighter than CRT projectors but may suffer from a lower contrast ratio.
- DLP Projectors: DLP technology uses a digital micromirror device (DMD) to reflect light onto the screen. DLP projectors are known for their high contrast ratios, compact size, and relatively low cost.
- LCoS Projectors: This technology combines the benefits of DLP and LCD, offering high contrast ratios, deep blacks, and vibrant colors, but at a higher cost.
