Pros and Cons of LCD

Liquid-crystal display (LCD) is one of the most popular and widely used forms of display technology in electronic devices. Even if you’re unfamiliar with the technology, chances are you’ve seen or even used an LCD device before. LCD is found in televisions, computer monitors, tablets, watches, smartphones, and more. But like all forms of display technology, it has its own advantages and disadvantages, which we’re going to discuss further in this blog post.

LCDs are capable of displaying either arbitrary images, such as a computer monitor, or fixes images like the numbers on a digital clock. Regardless of which type of images are being displayed, the underlying technology remains the same: a source of light (backlight) emits light through liquid crystals, causing them to form visible colors; thus, producing the image.

LCD Pros:

• Compact, requiring minimal space to integrate into an electronic device (note: this makes it preferable for tablets and other small devices).
• Lightweight.
• Very minimal power consumption. To put the efficiency of LCD into perspective, a typical CCFT backlit display uses 30-50% of the power of a CRT monitor, but an LCD display uses just 10-25%.
• Because it uses such little energy, LCDs emit practically no heat.
• Little-to-flickering on the backlit display.
• Thinner than CRTs and other forms of display technology.
• Expandable to large sizes with ease.
• The LCD grid is capable of improving overall image quality by masking the negative effects of spatial and grayscale quantization.
• LCD monitors and displays are often powered by an external 12V battery, meaning they will continue to operate even if the power goes out.
• Capable of navigating from DVI or HDMI without requiring conversion to analog.

LCD Cons:

• Somewhat limited viewing angle when compared to other forms of display technology.
• Greater color saturation due to its limited viewing angle.
• Brightness distortion may occur around the edges of LCD displays (a phenomenon that usually occurs in older models).
• Limited to a single native resolution.
• Low refresh rate.
• When exposed to high temperatures, LCD monitors and displays may lose some of their contrast.
• Difficult to watch an LCD TV when wearing polarized sunglasses.

As you can see, there are both advantages and disadvantages to LCD technology. However, most people will agree that the pros outweigh the cons. What do you think?
