Advantages & Disadvantages of LCD Technology
Liquid Crystal Display (LCD) technology, while we cannot live without it, comes with some advantages as well as some disadvantages. While earlier technologies were more reliant on Cathode Ray Tube (CRT) technology, LCD technology generally surpasses CRT technology for most applications. Yet, LCD technology continues to evolve and change. As mobile devices and smartphones emerge, many applications are now reliant on LCD touch screen technology. The fact remains, LCD technology is very much needed to display our powerful online graphics, video, and text solutions.
Advantages of LCD Technology
LCD technology, in its advancement over recent years, has proven to be advantage-rich, with the migration from CRT technology; however, LCD has its advantages and disadvantages from CRT as well. First, let's take a look at some advantages of LCD technology:
- Does not rely on phosphors
- Easy disposal
- Energy efficient, low-power
- Excellent contrast
- Immune to screen image burn-in
- Lightweight and compact
- Low flicker rates
- Screens are available in a vast range of sizes
- Sharp resolution and imagery
- Superior resolution
- Used in battery-powered electronics
- Uses a smaller pixelated format
Along with so many other advantages to LCD technology, researchers are continuing to improve the technology as they have for so long. The LCD of the future is predicted to absorb and convert light sources to create energy.
Disadvantages of LCD Technology
Even though LCD technology is used primarily in smartphones, tablets, and new devices, earlier CRT technology holds its own in many ways. Below are some disadvantages of LCD technology, where CRT technology is actually better:
When To Use What
- The color and contrast from various viewing angles is inconsistent
- Features poor black on dark imagery
- Motion blur is common
- With brightness from backlighting, imagery may appear flat
- Pixel-based display may be stuck on screen
- Fixed resolution
- Newer technology costs more
- Imagery not as good with analog interface
The types of technology you select ultimately depends on your needs, applications, and desires. For image quality in the engineering workplace, users gravitate toward LCD technology while photographers, artists, and television producers will lean toward CRT for display. These fields involve an area where viewing angles are critical, and LCD technology presents a problem here.
For new mobile devices, the decision is made. Most mobile phones use LCD along with Thin Film Transistor (TFT). Watch for bright colors, accurate imagery, and clear visibility in selecting LCD products. There are various manufacturers using different methods to produce LCD screens, and quality varies. If display matters, review LCD products carefully.
