Lcd Monitors: Unveiling The Myths And Misconceptions

LCD stands for Liquid Crystal Display. LCD monitors are flat-panel displays that use liquid crystals to control light passage and create images. They are thinner, more energy-efficient, and cheaper than older monitors. However, they have some drawbacks, such as limited viewing angles and lower image quality when compared to newer display technologies like LED and OLED.

LCD monitors are cheaper than LED monitors

When shopping for a new monitor, you will often come across the terms LCD and LED. But what is the difference between the two?

LCD stands for Liquid Crystal Display. This technology uses liquid crystals, which are substances with properties of both liquids and solids, to create images on a screen. When an electric current is applied, the liquid crystals align to allow or block light, creating the images you see on the display. LCD monitors use cold cathode fluorescent lamps (CCFLs) for backlighting.

LED, on the other hand, stands for Light-Emitting Diode. LED monitors use light-emitting diodes for backlighting instead of traditional fluorescent lights. LED monitors are a type of LCD monitor, and the term "LED monitor" is shorthand for "LED-backlit LCD monitor".

Now that we know the difference between the two, let's discuss why LCD monitors are generally cheaper than LED monitors. Firstly, LCD monitors have been around for longer and are more established in the market. As a result, the production costs are lower, and this savings is passed on to the consumer, making them a more budget-friendly option.

Additionally, LCD monitors have certain advantages over LED monitors that contribute to their lower cost. LCD monitors often have more uniform backlighting across the entire screen, providing consistent lighting. They also tend to emit less blue light, which can be beneficial for reducing eye strain. Moreover, LCD monitors usually come with matte screens, which are effective at reducing glare in bright environments.

However, it is important to note that in recent years, the price gap between LCD and LED monitors has narrowed as LED technology has become more common and accessible. While LCD monitors are generally more affordable, LED monitors offer superior performance in terms of picture quality, energy efficiency, and lifespan. LED monitors provide better contrast ratios, improved color accuracy, and enhanced visual clarity. They are also thinner, more lightweight, and have faster response times compared to LCD monitors.

In conclusion, while LCD monitors are typically cheaper than LED monitors, the price difference has been decreasing as LED technology advances and becomes more widely available. When choosing between the two, consider your specific needs, budget, and intended use to make an informed decision.

LCD monitors require a separate light source

Liquid-crystal displays (LCDs) require a separate light source to produce a visible image. LCDs use liquid crystals, which are substances with properties of both liquids and solids, to create images on a screen. These liquid crystals do not emit light directly and hence require a backlight or reflector to produce images. The backlight is usually the first layer from the back, with the light valves then varying the amount of light reaching the eye by blocking its passage.

LCDs are flat-panel displays that use the light-modulating properties of liquid crystals combined with polarizers to display information. Each pixel of an LCD consists of a layer of molecules aligned between two transparent electrodes, with polarizing filters that block light from passing through. When an electric current is applied, the liquid crystals align to allow or block light, creating the images we see on the display.

LCDs are commonly used in a wide range of applications, including computer monitors, televisions, and mobile devices. They have replaced cathode-ray tube (CRT) displays in almost all applications due to their compact size, low power consumption, and improved energy efficiency.

In the past, most LCDs were backlit with cold cathode fluorescent lamps (CCFLs). However, modern LCD monitors now typically use light-emitting diodes (LEDs) for backlighting, which offer several advantages such as thinner designs, lower power consumption, and longer lifespans. LEDs provide more even lighting compared to CCFLs, resulting in better image quality and energy efficiency.

While LCD refers to the display technology, LED refers to the backlighting technology used in LCD screens. It is important to note that not all LCDs use LED backlighting, and there are other types of backlights available, such as CCFLs and electroluminescent panels (ELPs). LED backlights can be further categorized into white LED backlights and RGB LED backlights, each offering unique advantages and use cases.

In summary, LCD monitors require a separate light source, typically in the form of backlighting, to produce a visible image. This backlighting can be provided by different technologies, with LED backlighting being the most common in modern LCD monitors due to its enhanced performance and energy efficiency.

LCD monitors have a limited viewing angle

The viewing angle of an LCD monitor is the angle at which the display is best viewed. LCD monitors have a limited viewing angle, meaning that the contrast and colour accuracy of the display will decrease when viewed from certain angles. This is due to the use of polarizing filters in LCD displays, which force the backlight to walk in a line before hitting the liquid crystal, which can make the light roll forward instead of walking. When viewed from a large angle, the light has no direct path from the backlight to the viewer's eye, making the image darker as the viewing angle becomes more obtuse.

The viewing angle can be improved by adjusting the contrast voltage, using a better polarizer, choosing the right liquid crystal material, and applying a premium quality orientation layer. The viewing angle can also be improved by changing the display mode, for example, by changing from a twisted nematic (TN) display to an in-plane switching (IPS) display, which offers superior performance and colour gamut with high luminosity.

LCD monitors with a limited viewing angle may be more susceptible to colour distortion and may appear darker when viewed from certain angles. This can be a problem for users who need to view the monitor from different angles or for multiple viewers who are sitting at different angles to the monitor.

LCD monitors with limited viewing angles may be cheaper and more energy-efficient than those with wider viewing angles. They may also have faster response times, making them a better choice for gaming. However, for users who require a wide viewing angle, such as graphic designers or video editors, an LCD monitor with a wider viewing angle may be a better choice.

Overall, while LCD monitors with limited viewing angles may have some advantages in terms of cost and energy efficiency, they may not be suitable for all users, especially those who require accurate colour reproduction and consistent brightness at different viewing angles.

LCD monitors are not suitable for video walls

LCD monitors are not the best option for video walls due to several factors, including size limitations, bezels, and brightness.

LCD video walls typically can't be made as large as LED walls. While they can be configured in different ways, they are restricted by the size of their screens, which limits the overall size of the video wall. LEDs, on the other hand, can be combined in unique ways to create huge displays. For example, one of the largest video walls in the world is an LED display in Beijing, measuring 250m x 30m.

Another issue with LCD monitors in video walls is the bezel, the frame around each individual screen. When multiple LCD panels are combined to form a video wall, the bezels create thin black lines where the screens meet, disrupting the viewing experience. While advancements in bezel reduction technology have resulted in narrower bezels, they are still noticeable, especially when displaying a single large image or a lot of data.

Brightness is another factor to consider when choosing between LCD and LED video walls. LCD video walls are generally not as bright as LED walls, which can be a problem in rooms with large windows and lots of natural light. While lower brightness may be preferable in certain environments, such as control rooms, where excessive brightness can cause headaches and eye strain, it limits the versatility of LCD video walls.

In addition, LCD monitors are unable to perform local dimming due to their consistent lighting. This affects the contrast ratio, which is the difference between the screen's brightest and darkest colours. LED displays, on the other hand, can achieve a higher contrast ratio of 5000:1 compared to the typical 1500:1 for LCDs.

Finally, LCD video walls tend to be more expensive to purchase and maintain than LED walls. The low-end average for an LCD video wall is $5,000-$6,000, while an LED display typically costs $40,000-$50,000.

In summary, while LCD monitors have their advantages, they are not the ideal choice for video walls due to size limitations, bezels, brightness, contrast ratio, and cost.

LCD monitors are not ideal for gaming

While LCD monitors are suitable for casual and less intense gaming, they are not ideal for high-performance and immersive gaming. This is because they often fall short in terms of deep blacks and contrast, which are important for creating vivid and immersive gaming visuals.

LCD monitors use cold cathode fluorescent lamps (CCFLs) for backlighting, which evenly illuminates the entire screen. However, this affects the contrast ratios and depth of blacks in the display. While LCD monitors offer good color accuracy and wide viewing angles, they are not as advanced as LED monitors when it comes to creating immersive gaming experiences.

LED monitors, on the other hand, use light-emitting diodes (LEDs) for backlighting, which generally provides brighter colors and sharper contrast. LED monitors deliver deeper blacks and more accurate colors, enhancing the gaming experience. The two types of LED backlighting are edge-lit and full-array. Edge-lit LED monitors have diodes around the perimeter, while full-array LED monitors have diodes across the entire back panel, offering better lighting control and image quality.

In addition, LED monitors are thinner, more energy-efficient, and have faster response times than LCD monitors. The faster response times are particularly important for reducing motion blur and ghosting, making LED monitors ideal for fast-paced games.

While LCD monitors are generally cheaper and more readily available than LED monitors, LED monitors are the preferred choice for gamers seeking high-performance and immersive gaming experiences.
