What is an LCD of Liquid Crystal Diode TV?
Acronyms are a dime a dozen when it comes to technology. Some are now so common place that we don't even ask what they stand for anymore - they have just become a standard, automatic term for something that is common and abundant. But 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.
Now for the technical bit. In case your ever wondered, 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. 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. 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.
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, ipods, 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.
In reality there are not that many company companies in the world that have the resources and economies of scale required for building LCD displays at the ready so you may be surprised at the branding within your branded box.
