In the market of display devices, LED monitors and liquid crystal displays (LCD) are two common types, they are different in many ways, each with its own advantages and disadvantages, which makes consumers in the choice of often caught in a dilemma.LCF will be in this article from the display principle, image quality, energy consumption, price and other perspectives to compare and analyse the LED monitors and LCD monitors, in order to better understand their respective characteristics. Their respective characteristics.

First, the display principle

Liquid crystal display (LCD)

Liquid crystal display is a use of the physical properties of liquid crystals to achieve the display function of the device. Liquid crystal molecules in the role of electric field will change the direction of the arrangement, thereby controlling the passage of light or not. LCD display internal backlight, the light emitted by the backlight through the liquid crystal layer and colour filter processing, and ultimately the formation of the image we see. Traditional LCD backlighting is usually a cold cathode fluorescent lamp (CCFL).

LED Display

LED monitor is actually a modified type of LCD monitor. The main difference between it and the traditional LCD monitor is the backlight source.LED monitor uses light emitting diodes (LEDs) as the backlight source, and the brightness and colour of the screen are adjusted through the control of these LEDs. According to the arrangement of LEDs and different control methods, it can be divided into side-entry LEDs and straight-down LEDs.

Second, image quality

1, brightness and contrast

LED display: LED display has an advantage in brightness, especially the straight-down LED display, which is able to achieve a high brightness level, which makes it display more clearly in a strong light environment, such as outdoor or well-lit indoor. In terms of contrast, because LEDs can more precisely control the local dimming of the backlight source, they are able to render deeper blacks and brighter whites, and contrast performance is usually better than that of traditional LCDs.

LCD monitors: Traditional LCD monitors have relatively low brightness and contrast. However, some high-end LCD monitors through technological improvements can also improve the contrast to a certain extent, but the overall visibility in bright light may not be as good as the LED display.

2, colour performance

LED monitors: LED monitors are able to provide richer and more vibrant colours. This is because LED backlighting allows for better wide colour gamut coverage and more natural colour transitions. Especially for displaying high-quality pictures, videos and game screens, LED monitors can present more realistic visual effects.

LCD monitors: the colour performance of ordinary LCD monitors is relatively weak, but some professional-grade LCD monitors through the use of high-quality liquid crystal materials and colour calibration technology, you can also get a good colour accuracy and colour gamut performance, but from the perspective of the overall market, the average level of its colour performance is lower than that of the LED monitor.

Third, energy consumption

LED monitor

LED monitors excel in energy consumption. Due to the high energy efficiency of the LED backlight itself, LED monitors are able to consume less power at the same brightness compared to traditional LCD monitors (especially those using CCFL backlight). This not only helps to save on electricity bills, but also offers certain advantages in terms of environmental protection, which is an important advantage for users who need to use their monitors for long periods of time.

Liquid Crystal Display

Traditional LCD monitors consume relatively high amounts of energy, especially models that use cold cathode fluorescent tubes as the backlight. These tubes require a high voltage to operate and there is some loss in the energy conversion process, resulting in higher overall energy consumption. However, as technology improves, the energy consumption of some new LCD monitors is gradually decreasing, but there is still a gap compared to LED monitors.

Fourth, the angle of view and response time

1, viewing angle

LED monitors: most LED monitors have a wide viewing angle, when viewing the screen from different angles, the brightness and colour of the image changes less, to ensure a better viewing experience. This is very favourable for more than one person at the same time to watch the screen content or the need to use the monitor at different angles.

LCD monitors: LCD monitors have a relatively narrow viewing angle, and when the screen is viewed from the side, the image may be darkened, colour distortion and other phenomena. However, some high-end LCD monitors can improve the viewing angle problem to a certain extent by adopting special liquid crystal arrangement technology.

2, response time

LED monitors: LED monitors usually have a shorter response time, which means that when displaying dynamic images, such as in games or fast-moving video scenes, they can switch pixel colours faster, reducing the phenomenon of shadow dragging and making the picture smoother.

LCD monitors: Traditional LCD monitors have relatively long response times, which may result in ghosting when displaying fast moving images, affecting the viewing experience. However, there are also some high-end LCD monitors that have reduced the response time through technical improvements.

Fifth, price

LED monitor

LED monitors due to its technical advantages and better performance, the price is usually relatively high, especially some high-end LED monitors with high resolution, high refresh rate, wide colour gamut and other features. However, with the popularity of LED technology, the prices of low-end and mid-range LED monitors are gradually decreasing and becoming more affordable.

Liquid Crystal Display

LCD monitors come in a wide range of prices, from low-end to high-end. Comparatively speaking, some ordinary LCD monitors are cheaper, making them an affordable choice for users with limited budgets and not particularly high requirements for display performance.

Sixth, the conclusion

In summary, LED monitors and LCD monitors have their own characteristics. If you are pursuing higher image quality, including better brightness, contrast, colour performance, wider viewing angle and shorter response time, as well as having certain requirements on energy consumption and a relatively sufficient budget, then LED monitors will be a better choice. However, if you have a limited budget and are not very demanding in terms of display performance, and only use it for simple daily office and basic entertainment purposes, LCD monitors can also meet your needs. When choosing a monitor, LCF recommends that you make your decision based on your actual usage scenario, budget and focus on display performance.
