Electronic display technology has evolved drastically over the past few decades. No longer are cathode ray tubes (CRT) the de-facto standard. Now, electronic displays such as televisions, computer monitors and tablets typically feature either liquid-crystal display (LCD) or light-emitting diode (LED) technology. In this post, we’re going to take a closer look at the pros and cons of LCD technology.
Arguably, one of the greatest benefits of LCD is its slim, lightweight design. You may recall the old CRT electronic displays from back in the 80s and 90s. Although they were effective at projecting displays, they were far heavier than today’s LCD displays.
Another advantage of choosing LCD is its low power consumption, which subsequently means a lower operating cost for the end user. Just how much power will a LCD display save? LCD monitors that feature a CCFT backlight will use roughly half of the power of a CRT monitor of similar viewing size. If the LCD monitor features an LED backlight, it will use just 10-25% power.
Because they draw significantly less power than other electronic displays, LCD tends to produce very little heat. Why is this important? Well, heat and electronics don’t mix. When displays produce excessive heat over a prolonged length of time, they become susceptible to internal damage. Thankfully, this isn’t a problem with LCD displays, however, as they produce minimal heat when compared to other electronic display technologies.
LCD monitors and other electronic displays typically have little-to-no refresh rate flicker. This is due to the fact that liquid crystal display pixels retain their state between refreshes.
Of course, there are also some “potential” disadvantages associated with LCD technology, such as uneven backlighting. Some older model LCD displays may suffer from uneven backlighting, in which certain areas of the display are brighter than other areas (usually around the edges).
While not a problem that affects all LCD displays, some may have limited viewing angles. This results in varying levels of color, saturation, brightness, and contrast. Much like the aforementioned problem of uneven backlighting, however, it’s usually the older LCD displays that suffer from limited viewing angles.
Liquid crystal display English is LiquidCrystalDisplay, abbreviated as LCD. Its main principle is to use electric current to stimulate liquid crystal molecules to produce dots, lines, and surfaces to form a picture with the lamp on the back.
Advantages of lcd liquid crystal display:
1. Thin body, saving space: Compared with the more bulky CRT display, the LCD display only needs one-third of the space of the former.
2. Power saving, no high temperature: It is a low power consumption product, which can be completely non-hot. Compared with other display screens, high temperature is unavoidable due to imaging technology.
3. No radiation, good health: The LCD screen is completely free of radiation, which is a boon for people who use it at work.
Fourth, the screen is soft and does not hurt the eyes: Unlike CRT technology, the LCD screen does not flicker, which can reduce the damage of the screen to the eyes, and the eyes are not easy to fatigue.
The advantages and disadvantages of LCD
Nowadays, there are many low-priced LCD screens on the market, and many businesses have also touted LCD to the sky. However, LCD has many very obvious advantages, but due to various reasons, the current low-priced LCDs are only belonging to The "low-end" in LCD products has many inherent shortcomings. Let's analyze in detail what are the shortcomings of these LCD screens.
Disadvantages of lcd liquid crystal display:
1. Price
2. Interface
The digital interface of the LCD screen is very cold. In theory, the liquid crystal display is a pure digital device, and the connection with the computer host should also be a digital interface. The advantages of using a digital interface are self-evident.
3. Small viewing angle
4. The response time is too slow
