6 Differences Between LCD and LED on Laptops or Monitor PC

The screen is one of the input and output devices of computers, especially laptops, which function to display the output of the computing process on a laptop in the form of a graphical display. The screen is the most vital component of laptops and computers because it functions as a “link” between computer language and human language. For example, you want to know how to find out the bits of your laptop. Since modern computers were created, the screen has had this function, even though computers were still using CLI (Command Line Interface) based commands. Unlike computers and laptops, today that have implemented GUI (Graphical User Interface) based commands.

What is clear, laptop manufacturers can’t use CRT screens or tube screens as laptop components. The reason is only one because it is heavy. This is against the wishes of users who want a “computer” that can be carried anywhere. Therefore, all laptop manufacturers use thin screen technology as a laptop component. In fact, even the most sophisticated computers today also use screens with LED technology to display their computing results.

This thin screen technology is divided into two, namely LED and LCD. Well, often, people do not know the difference between LED and LCD because they both carry thin screen technology. People who are not familiar with the laptop’s hardware will be confused with the following questions: “What type of screen does my laptop use?” “Is it an LCD or LED, or even Slim LED?” “Can the LCD be used to replace my broken laptop LED?” or “Can the LED be used to replace my broken laptop LCD?”

Indeed, at first glance from the physical, LED, and LCD look the same. But apparently, there are differences between the two types of thin screen technology. To answer all the questions above, you need to know the difference between LEDs and LCDs. On this occasion, we will discuss the differences between LEDs and LCDs on laptops. Alright, let’s start the discussion:


LCD stands for Liquid Crystal Display. From the word liquid in its abbreviation, you would have guessed that this LCD screen contains liquid. So, this LCD is composed of molecules of liquid crystal material, which, when aligned and electrified, the liquid can produce light.

In physical appearance, LCD is thicker than LED. Then, the cable slot extends. In addition, the LCD requires a lot of electricity consumption. The electrical power required by the LCD screen is around 22 Watt, and this number can vary depending on the size of the screen used. This makes an LCD screen on the laptop must be connected to the inverter unit. This is one of the reasons why laptops that still adopt LCD technology on the screen have an average battery life that cannot last long. The durability of a laptop battery that uses an LCD is only about one to two hours. In a way, the LCD is known to be wasteful of power.

The way the LCD works is that the screen is lit using a CCFL (Cold Cathode Fluorescent Lamp) tube. When the LCD screen is turned on, the fluorescent tube will form mercury vapor (mercury) low pressure. Although the mercury content in the LCD screen is low, the LCD is still less environmentally friendly because the mercury content still exceeds the minimum limit.

At the beginning of its appearance, the LCD screen has a thin size and is more energy-efficient when compared to a CRT screen or convex screen. LCD technology has also been used over time on TVs, cellphones, computer monitors, laptops, and other electronic devices. Despite this, the LCD does not present the best picture quality. However, for people at that time, the image quality produced by the LCD was quite good. LCD monitor function that can make the size of electronic devices smaller has become a technological sophistication at that time.

When asked about its durability, the LCD has a resistance of approximately 60,000 hours, or only has a life of up to 11 years, if used approximately 15 hours per day.

Manufacturers use LCDs since laptops were first produced in the 90s until around 2008 or 2009. Between these two years, laptop manufacturers have begun to abandon LCD technology and have begun switching to LED technology. If you buy a laptop from 2009 onwards, it is almost certain that the screen used is no longer using an LCD but is already using an LED.


LED stands for Light Emitting Diode. From this, you can interpret that the LED screen is a screen that consists of small tangible electronic diode components that can emit light. LED screens can emit visible light (as we normally see every day) and also that which cannot be seen (for example, such as infrared light used to see in complete darkness). LED (Light Emitting Diode) is a newer technology, more energy-efficient, and also clearer. However, LED is also a component that can emit light emission.

In a way, LED technology is the second generation screen technology used on laptops after LCD. The majority of laptop manufacturers now use LEDs because this technology has more economic power consumption than LCD. The power consumption of the LED screen is approximately 8 Watts, and this number can vary depending on the screen size. As discussed earlier, this is why the laptops output in 2009 and above have an average battery life that is more durable, or the term saves battery.

The way LED works starts from the discovery that electrons flowing in P-N connections also release energy in the form of light and heat energy. LEDs are made to further improve power efficiency when emitting light. To get light emission from semiconductors, LEDs use doping. Doping used is Gallium, Arsenic, and Phosphorus. Different types of doping will produce different colors of light, as well. Currently, the colors of light that are widely used are red, yellow, and green. Although there is a light blue diode, the color is very rare.

Besides saving energy, LED screens to have a much brighter and sharper picture quality than LCD screens. That is because the Dynamic Contrast Ratio on the LED screen is much larger than the LCD. The life of an LED screen is also quite long, which is approximately 100,000 hours, or 18 years if it is used approximately 15 hours per day.

If you look at it physically, you won’t find a significant difference between LCD and LED. Both have minimal thickness. The most obvious technological difference is that the inverter cable’s LED screen has not been used because, indeed, LED technology does not use an inverter.

From the explanation we have said, then we can draw conclusions about the differences between LEDs and LCDs on laptops:

1. LED technology is more economical in electricity consumption than LCD technology

2. The sharpness of the image on the LED screen is higher than the LCD

3. The LED material is more environmentally friendly

4. Longer lifespan for LEDs than LCDs.

5. In terms of Contrast Ratio, these two products have differences. Contrast Ratio is the distance between black and white. The farther the distance, the more real the picture.

6. LED screens are brighter and more realistic in color than LCD screens.

This is our article this time about the differences in LEDs and LCDs on laptops. Hopefully, this article can be your new knowledge about computer hardware, especially laptops. Perhaps, this difference is also one of the tips on choosing a laptop for graphic design. By the way, the cause of a blank laptop screen does not distinguish the screen technology used on your laptop. This is our article this time.

The 5 Main Advantages of IPS Technology

We have already had the opportunity to introduce IPS (In-Plane Switching) technology, talking about the screens of smartphones, televisions, and monitors. The time has come to investigate the topic, to understand what the advantages of using this LCD technology are.

IPS panels have existed for a long time; but they were used, so far, in the professional field (and in particular photographic), for their ability to reproduce colors as faithfully as possible, as well as brilliance and contrast.

Now, LG has included this technology in most of its products (in addition to the aforementioned monitors and smartphones, also for digital signage ) to offer the best image quality. How?


Here are the five main advantages of using IPS.

1. More real colors

More brilliance and contrast (combined with uniform color temperatures) allow you not to lose any image detail. So much that it will seem real: the colors are so similar to the real ones that you will have the feeling of experiencing the film or the program in the first person.

2. Color calibration

LG Display, a company that is part of the LG Electronics group, is the division that deals with the production of screens for all LG products. And that has developed color calibration tests to ensure a more accurate rendering.

3. Greater viewing angle: up to 178ยบ

IPS technology allows you to see the best image from any angle, up to 178 degrees (horizontally but also vertically). Whether you are standing, sitting or lying down, you will not perceive any change in color or loss of parts of the image. This makes the difference, especially when you find yourself in front of the canvas (and friends will queue up to watch the game or the X-Factor final from you).

4. Prevents eye strain

IPS technology allows you to reproduce an image with more details: this helps to avoid eye fatigue. Even the continuous and very rapid refresh of the images allows a more comfortable vision, even of action films and sports shows.

5. Savings

IPS is an ECO-Friendly technology: the light is emitted through high-efficiency LEDs, which allow to considerably reduce energy consumption.

What Do IPS Mean?

IPS is an English acronym meaning In-Plane Switching, literally ” variation in the plan “.

It refers to the technology with which some of the best PC monitors currently available are built.

In fact, compared to a TN panel, an IPS panel has liquid crystals arranged horizontally with respect to the panel surface. The basic operation is the same as in other LCD screens: what changes is the way the crystals react to the current.

In fact, subject to the action of an electric field, the liquid crystals rotate on themselves, but always remaining parallel to the panel.

Presented with the real novelty of LCD screens after the introduction of TN panels, IPS technology managed to overcome their problems.

In fact, IPS monitors have undeniable advantages:

  • greater brilliance and color definition;
  • much wider viewing angles.

These two features, combined with greater black density and color rendering, make IPS panels perfect for professional graphic applications.

Not only that, but IPS are also the displays of many TVs and the screens of most smartphones on the market today.

However, the parallel arrangement of the liquid crystals impairs the reactivity in the rotation of the crystals on themselves. Here are the main defects of IPS monitors:

  • Response times on average higher than a TN monitor
  • low refresh rates, in fact often fixed at 60 Hz
  • higher cost with the same specifications.

In recent years, IPS technology has evolved and it is not difficult to find IPS monitors with high refresh rates and low response times. But the cost goes up accordingly.

Android from A to Z: What is an IPS Screen?

IPS stands for In-Plane Switching.

It is a technology used in the realization of LCD displays that solves some limitations of the previous TN (Twisted Nematic) technology, in particular with regards to viewing angles and fidelity in color reproduction.

In the IPS screens, the liquid crystal molecules move parallel to the panel and not perpendicularly, and this allows viewing angles close to the flat angle, with a consistent and accurate color rendering. To have a demonstration of the goodness of IPS technology, you can refer to a comparison made by Japan Display with TN technology.

Initially, IPS panels were very expensive and intended only for high-end monitors, but over time they have become widespread in the consumer market. In the mobile environment, and in general in touch-based devices, IPS panels were immediately highly appreciated also because they do not lighten or otherwise change the image rendering when touched.

Among the defects of the IPS technology, apart from the price, there were, in particular, the greater response times and the higher energy expenditure than the TN, both problems largely overcome, even if in the gaming field there are still those who prefer the latter, in the light of the fastest response.

What is IPS?

IPS, also known as In-Plane Switching, is a type of screen and vision technology.

Specifically, an IPS panel is a type of TFT LCD (or “active matrix” LCD). LCD, or liquid crystal display, indicates the use of light-modulating properties from unlit liquid crystals to produce flat panels or electronic screens. TFT, which means Thin Film Transistor, is a variant of the LCD monitor created and marketed for its properties of color enhancement, contrast, and black levels. The two most common types of LCD TFTs are the IPS and TN screens.

The TFT LCD screen (IPS monitor with active matrix) was developed by Hitachi in 1996 as a solution to the limits of the late 80s LCD TFT (Twisted Nematic) LCDs, not standard IPS LCDs. The TN screen is known for its viewing angle limitations, such as inversion of colors at extreme angles and low color quality. In contrast, IPS monitors provide wider viewing angles and higher quality color reproduction by making pixels parallel, rather than perpendicular. In an IPS display, the liquid crystals are parallel to the panels when they receive energy. In a TN screen, the crystals are oriented perpendicular to the upper part of the panel. High-performance tablets and smartphones use IPS vision technology because they are often used to view movies, make video chats and store photos. A better viewing angle and color characteristics guarantee better user experience. Creativity professionals benefit from the use of an IPS screen because an IPS LCD with a wider color gamut and wider viewing angles allows for greater aesthetic accuracy and therefore excellent quality.

Other versions of IPS include the following technologies:

  • Super TFT (IPS) for a wider viewing angle
  • Super-IPS (S-IPS) to eliminate the effect of changing colors and improve the pixel refresh rate.
  • Advanced Super-IPS (AS-IPS) for high transmittance
  • Enhanced IPS (E-IPS) for better diagonal viewing angle and reduced response time
  • Horizontal IPS (H-IPS) for an improved contrast ratio and an Advanced True White polarizing film that creates a more natural white color
  • Professional IPS (P-IPS) for true color depth

Is IPS suited to my needs?

An IPS monitor, also known as the In-Plane Switching panel, uses a type of high-quality vision technology typically used in high-performance computer, laptop, tablet, and smartphone screens. IPS offers a better user experience thanks to the wider angle and better color quality, as well as display features evolved over time compared to the introduction of TN effect LCD screens, used a lot in the 90s.

To decide if an IPS monitor is the best choice for your needs, first understand the TFT LCD vision technology. LCD TFT stands for “Liquid Crystal Display” and “Thin Film Transistor” (thin-film transistor). The LCD screen is composed of polarizing material and liquid crystals. TFT LCDs, also known as “an active-matrix “, were born as a variant of LCDs. TFT LCDs improve the color, contrast and response times of passive matrix LCDs.

The two most common types of LCD TFTs are the IPS LCD TFT and TN LCD TFT screens. TNs usually have a faster response time, which guarantees better entertainment experiences for those who watch sports or play video games, but IPS was born to solve TN screen problems, such as reduced viewing angle and the low quality of color reproduction. If you use your laptop or smartphone for creative activities, watching movies and videos, video chatting or uploading photo albums, you should choose an IPS, which gives you the best viewing angle and maximum color accuracy.

What are the qualities of IPS compared to TFT?

IPS (In-Plane Switching) is one of the most common types of TFT LCD screens. The TFT LCD screen improves the image quality of a normal LCD screen thanks to thin-film transistor technology. The IPS LCD screen, a variant of the TFT LCD (active matrix) improves the screen technology ensuring better color reproduction and a wider and more precise viewing angle. TFT LCD IPS technology is widely used for desktop and laptop computers, tablets and smartphones with high performance.

LCD stands for Liquid Crystal Display. It is a type of thin screen that forms a luminous panel display using two layers of polarized panels and a liquid crystal solution. Light is projected through liquid crystals to produce an image, but since liquid crystals are not illuminated, they need a backlight.

TFT LCDs (also known as active matrix LCDs) were created to improve colors, contrast and response time in LCD screens. The two most common types of LCD TFTs are the TFT TN LCDs (not standard IPS) and the IPS TFT LCDs. A monitor with an IPS screen offers improved features such as optimal viewing angles, precise colors, invariable color reproduction, and reduced energy consumption. In summary, IPS is a variant of the TFT LCD that improves the technological limits of TN panels, ie reduced viewing angles and color reproduction.
