What Is a Sub-field Drive on a Plasma TV?
If you are in the market for a Plasma TV, you might have heard of something called a sub-field drive. So, what exactly is a sub-field drive and why is it important?
A sub-field drive is a technology that is used in Plasma TVs to improve their picture quality. Essentially, a Plasma TV works by thousands of tiny cells filled with a mixture of gases that are excited by electrical pulses to create an image. The sub-field drive technology helps these cells turn on and off more quickly, resulting in a smoother and clearer picture.
The sub-field drive works by dividing the screen into smaller sections, or sub-fields, and displaying the image on each one of these sub-fields. So, instead of displaying a full image all at once, the TV displays the image in small chunks, which allows for much faster refresh rates. The sub-field drive technology can display up to ten different sub-fields in a single frame, which results in a smoother and more detailed image.
The amount of sub-fields that a Plasma TV can display is measured in Hz (Hertz). For example, a Plasma TV with a sub-field drive of 600 Hz can display up to 600 different sub-fields per second. This means that the TV can refresh the image on the screen 600 times per second, resulting in a much smoother and clearer picture than a TV with a lower refresh rate.
Another benefit of sub-field drive technology is that it helps reduce motion blur. When you are watching a fast-paced action movie or sports game, you might notice that some parts of the image look blurry or distorted. This is because the TV is not able to keep up with the fast-moving images on the screen. With a sub-field drive, the TV can display each moving object more quickly and accurately, resulting in much less motion blur.
In conclusion, a sub-field drive is an important technology in Plasma TVs that helps improve their picture quality by displaying the image in smaller sections or sub-fields. This technology results in a smoother and more detailed image, and also helps reduce motion blur. So, if you are in the market for a Plasma TV, be sure to look for one with a higher sub-field drive for the best picture quality.
