Liquid-crystal displays (LCDs) are found nearly everywhere. Even if you’re unfamiliar with the technology, you’ve probably seen and used an LCD before. From computer monitors and smartphone displays to digital watches, smart appliances and more, countless display devices use LCD technology. There are several different types of LCD technologies, however, one of which is vertical alignment.
The Basics of Vertical Alignment LCD Technology
Vertical alignment is a type of LCD technology that’s characterized by vertically aligned pixels. Like all LCD technologies, it uses liquid organic material for the pixels. Whether it’s a standard high-definition (HD) or ultra-high-definition (UHD) LCD, each of the LCD’s pixels contain liquid material. Vertical alignment LCD technology simply means the liquid pixels run vertically to the glass substrate on which they are used.
How Vertical Alignment LCD Technology Works
As previously mentioned, vertical alignment LCD technology works using vertically aligned liquid pixels, which are generally made of an organic material. When the LCD is turned off, the liquid crystals are perpendicular to the glass substrate. When the LCD is turned on, the liquid crystals receive a voltage that causes them to change to a vertically oriented position. Light created by the backlighting solution can then pass through the liquid pixels, thereby producing images.
Pros and Cons of Vertical Alignment LCD Technology
There are both pros and cons associated with vertical alignment LCD technology. For starters, it’s able to produce stronger black backgrounds than other LCD technologies. In background images where the screen is black, vertical alignment delivers a deep tone that contrasts with the surrounding color or colors.
All LCDs are capable of producing black backgrounds. However, those produced using vertical alignment LCD technology are typically stronger and darker than those producing other LCD technologies. In addition to stronger black backgrounds, vertical alignment LCD technology offers a wider viewing angle than that of other LCD technologies.
With that said, vertical alignment LCD technology suffers in terms of color transitioning. When the display changes from one color to another color, it creates a minimal form of distortion.
After reading this, you should have a better understanding of vertical alignment LCD technology. It’s a relatively new type of LCD technology that involves the use of vertically aligned pixels. The liquid pixels are perpendicular to the glass substrate by default, but when they receive a voltage, they shift their position, thus becoming vertically aligned with the glass substrate.
