What to Look For in an LCD TV
Have you ever wondered how they make LCD TVs? Here’s a small taste of what you might be looking for with an easy-to-understand explanation.
The LCD part of an LCD TV stands for liquid crystal diode, a phrase that many people have probably never given a second thought to even though these liquid crystal diodes are prevalent in today’s technology. Liquid crystal displays are used in quite a number of appliances and electronic devices that are used on a daily basis from watches and mobile phones to computer monitors and televisions. Consumers look at them and use them without thinking about the technology it takes to create them.
However, when choosing a new TV set, consumers should begin to explore their options and take a closer look at LCD technology. This is particularly true since many people are opting to purchase televisions with an even wider display capacity such as HD TVs. The price tag is much larger on the larger TVs no matter which type a consumer is purchasing. Therefore, it’s important to understand as much as you can about your LCD TV before making the purchase. It could be that you simply will never use the high end capability of your new televisions, so why pay for the extra capability?
An easy way to consider what liquid crystal diode technology is would be to take a look at all of the items that you use throughout your day that includes a digital display of numbers or letters. Typically this display appears in bright red digits. LCD technology is used in digital clocks that are designed for home use as well as in automobile dashboards. You can also see this type of LCD display on some types of bathroom scales, microwaves, stereos, CD players, DVD players, calculators, and more.
LCD technology typically makes use of a twisted nematic liquid crystal (TN liquid crystal)when used in display applications such as those mentioned above as well as LCD projectors, LCD monitors, and LCD TVs. This crystalline structure has a natural feature that allows it to react to electrical currents. This reaction is what allows the display to appear the way that it does. In essence, the electrical current causes the twisted part of the liquid crystal to untwist resulting in the visual display that is seen with the human eye.
Of course, a lot more goes into the creation of an LCD TV. The TN liquid crystals are placed in between two panes of polarized glass that are perpendicularly aligned. Light is sent through the TN liquid crystals via an internal florescent bulb. The intensity of the light is manipulated and the result is a display that passes through to the outer glass pane. The light causes the TN liquid crystals to untwist in varying degrees resulting in light, dark, and in between shading displays.
And that my friends, in a nutshell is how the marvel of the modern flat LCD television or monitor works. As technology progresses, we will without doubt see new variations and flavors with greater resolutions and features, but this core technology is likely to be the bedrock of out televisual displays for some time to come.
