What is a monitor used for? Monitors display anything computer users access: documents, websites, productivity tools, computer-aided design (CAD) programs, photo-editing programs, video games, films, and more.

Researchers from the Fraunhofer IPMS have developed a semi-transparent high resolution OLED microdisplay, that is significantly lighter than conventional combiner-based optical see-through near-to-eye systems. The specification of the display was not disclosed, but one can see it's a monochrome yellow panel.

Mini-LED screens are similar to standard IPS LCD screens, but they use smaller, more numerous LEDs for their backlighting. This means greater image control and contrast, allowing darker blacks and lighter whites.

Computer monitors come with a range of screen technologies including the VA, TN, and IPS types of LCD screens. This guide explores these types of computer displays and their differences.

Just what is a computer monitor? It is the display screen that forms the user interface for the computer. It displays the information the user is accessing and represents the computer’s outputs in response to the user’s inputs.

Best display type

Organic light-emitting diodes (OLEDs) use carbon-based materials to achieve improved image brightness, contrast, and colour ranges. Since these screens don’t require a backlight, they can be made very thin: an ideal feature for laptops.

The monitor offers a brightness of 600 nits (peak), a 0.1 ms response time, and HDMI, DP, Dc and USB interfaces. The lifetime of LG's 30-inch transparent WOLED is quoted at 30,000 hours. Contact us if you're interested in this monitor, or in other solutions based on LG's range of transparent OLED displays (30-inch, 55-inch and soon 77-inch) or BOE's transparent OLEDs.

How do VA panel vs IPS panel specs differ? Though they’re both enduring, common display styles, VA vs IPS monitors are different in terms of speeds, contrasts, and viewing angles.

Today, LG Display is producing large-area transparent OLEDs - in sizes ranging from 30-inch to 77-inch. These are mostly used in signage and commercial settings. Some PMOLED producers are offering small (around 1-2 inch in size) transparent OLEDs.

During Displayweek 2024, Visionox demonstrated many OLED display technologies and panels, and also an interesting microLED prototypes (produced by its subsidiarity Vistar).

OLED technology enables thin, efficient and bright displays and lighting panels. OLEDs are currently used in many mobile devices, some TVs and lighting fixtures. OLED displays offer a better image quality compared to LCD or Plasma displays - and can also be made flexible and transparent.

Towards the end of 2023, Seoul's Metropolitan Government has initiated a new pilot test at Myeong-dong Station that offers an AI-powered translation service for tourists that enables them to communicate with the subway staff through a transparent 55" LG OLED display.

Screen size, resolution, and aspect ratio are key factors when selecting laptops since they directly determine the computer’s size, weight, and how things will be displayed. 720p resolution may be adequate if you prefer a smaller screen and lighter laptop since high definition may have no appreciable effect in a small display. As for aspect ratio, 3:2 laptops can be perfectly suited for working with basic documents, but using one to watch videos at a 16:9 ratio will mean large black bars at the top and bottom.

Earlier this year LG Display started producing its 30-inch 1366*768 transparent OLED panels. China-based CEOLED are now offering a monitor based on this panel.

Taiwan-based PC cases and accessory maker Lian Li is showing a new motorized gaming desk with a built-in  30-inch transparent OLED display.

As noted above, TN vs IPS differences start with their speed. TN displays have far superior response times and refresh rates. Hardcore gamers demand 60 Hz (the image refreshed up to 60 times per second) as a baseline, and TN displays can get up to 540 Hz. These monitors reduce motion blur and the lag between user input and the results onscreen. TN monitors also deliver these advantages at fairly affordable prices with high energy efficiency.

These crystals’ vertical (in the layer stack) active state gives IPS displays wide viewing angles, letting more people in the room see them. IPS monitors also have sharp colour accuracy, making them good choices for creative professionals who need the most true-to-life displays.

What is an LCD monitor? Liquid crystal displays are one of the most common types of monitor. Their titular liquid crystal exists in a semi-liquid state and is very sensitive to temperature changes. Applying heat changes their molecular structure and ability to pass light through.

IPS monitors are the better choice for most professional situations, though. They outperform TN displays in their viewing angles and colour accuracy, which makes them better suited for producing creative works and working in teams or open areas.

When considering VA vs IPS displays, think about their operating environment, the work they’ll be used for, and their cost. Monitors for industrial shop floors won’t need photorealistic, immersive colours and contrasts, but they could require large viewing angles for their wide, open environments. Professional designers should seek the colour capabilities of IPS, and people working with video may also prefer IPS vs VA for its faster speeds.

The three companies started collaborating back in 2020, to realize how OLEDs can benefit aircraft interior design. For this project, LG Display developed aircraft-specific OLED panels, ensuring higher reliability and safety compared to regular OLED panels. The new smart cabin concept includes a 55" OLED panel that is installed at the aircraft entrance, curved OLED at the aircraft's ceiling, 30-inch transparent OLED panels placed in the cabin partitions, and a 27-inch OLED panel in the crew galley.

ViP offers a high improvement in aperture ratio (69% up from 29%) which results in low power consumption and brightness (up to 4X according to Visionox), improved lifetime (up to 6X), improved PPI and more.

High-Density Interconnect (HDI) is an advanced technology used in manufacturing high-density printed circuit boards (PCBs).

The Fraunhofer researchers developed a new semi-transparent OLED-on-silicon microdisplay technology, which enabled the new display. The technology is based on modern and advanced silicon CMOS processes, applied to silicon-on-insulator (SOI) wafers. The new wafer technology can be used to implement very thin circuitry layers. With the help of a specific IC design and an appropriate transfer-to-glass process flow, the transparent OLEDs were enabled.

IPS displays can be more expensive, but they excel in their speeds and colour capabilities. IPS also has wider viewing angles, meaning it’s easier for people to see the display from wherever they are in the room.

Another emerging feature is HDR: High Dynamic Range technology boosts the monitor’s contrast and colour capabilities, though only with HDR-enabled computers and HDR-supported content.

What is an IPS monitor? With in-plane switching LCDs, the crystals sit parallel to the screen’s layers in their default state, and they rotate rather than twist to let light through.

LG Display says that its WOLED TV and gaming displays have been awarded UL's low-plastic verification, given to products in which the plastic usage accounts to less than 5% of their total weight.

As OLED technologies are making inroads into the aerospace industry, LG Display has teamed up with Boeing and LIG Nex1 to introduce a new aircraft smart cabin concept, utilizing the company's latest OLED displays.

Modern TN displays have extremely fast response times and refresh rates, meaning reduced image blurring and near-instant responses to user inputs. This makes them the monitor of choice for competitive video gamers who need lightning-fast performance. Those gamers will also sit directly in front of their monitors and can accept lower colour accuracy, though; TN displays tend to have limited viewing angles and colour ranges compared to IPS.

As the centre stage for the computer, displays continue to be one of the fastest-developing areas of technology. The bendability of OLED displays allows innovations like curved, ultrawide monitors that give the user an immensely immersive experience. OLED technology has further potential in screens embedded in car windows or even foldable screens that could be rolled up like paper.

What is a TN monitor? Twisted nematic liquid crystals are one of the oldest LCD types, and they remain popular today for their high speed and low power consumption. In their ‘normally white’ resting state, the pixel molecules twist into a helix that aligns with the two substrates’ 90° shift in polarisation, allowing light through. Passing a current through the pixel breaks up this helix and blocks light, as with a number’s single ‘dark’ portion on a classic, basic digital clock.

Laptops spearheaded the development of flatscreen computer displays out of necessity: bulky cathode ray tube screens would never have worked for the flat profiles of laptops. These days, laptop displays can be just as powerful and impressive as their desktop counterparts. Along with VA, TN, and IPS LCD screens, laptops also come with OLED and mini-LED screens.

The pilot was successful, and Seoul's Metro expanded the service to 11 stations, throughout Seoul. This is one of the first useful applications of transparent OLED displays, and it is great to see it expanded in Korea. We do not know whether there are any plans to roll out more such displays in Korea.

That straight resting alignment contributes to VA displays’ strong contrasts, letting them produce truer black backgrounds that contrast well with adjacent colours.

This is the first subway service in Korea to install transparent OLEDs (similar projects have already been deployed in China, Russia, and Japan). The idea is that the OLEDs create a "comfortable and smart on-board experience by displaying varied content". LGD initially installed 16 OLED displays on a single train with eight cars running on the inaugural GTX line between Suseo and Dongtan. Going forward, the GTX plans to install OLED panels in all of its trains.

Several companies develop transparent OLED (also referred to as T-OLED) technologies. While there's no inherent technology barrier towards transparent OLED displays, finding actual applications for such displays is not easy.

The DK-07, currently in prototype stage, adopts LG Display's1366x768 transparent WOLED display. The desk is also a PC case. It's not clear what is the use case for the transparent display - the company is saying it can be a secondary display for your computer - and it is also showing a demo in which the transparent OLED displays ocean waves to create a nice effect. The display does not cover the entire desk area, as you can see in the image above.

OLED technology can also be used to make lighting panels - these are thin, area-lit and efficient lighting panels, that can be made transparent. Unlike displays, transparent OLED lighting panels have more immediate applications (embedded in windows, for example). Unfortunately OLED lighting has been a challenging market and currently there's not much R&D for transparent OLED lighting. In April 2012 we posted our hands-on review with a transparent Tabola OLED lighting panel sample.
