Since the release of USB in the mid-1990s, different USB versions have been released throughout the years. The main difference between each version is the data transfer speed and the connection types that it's available with. You can see a rundown of the different versions below. USB 3.0 was initially released in 2008, and its name was changed to USB 3.1 Gen 1 after USB 3.1's release in 2013, so both titles can be used interchangeably.

Every day we use many different electronics that require Universal Serial Bus (USB) connections. We constantly use different USB cables and connections, from phones to hard drives to printers. Because of this, monitors include USB hubs so that we can easily connect our external devices, making it easier to work. There are three main types of USB connections you can find on monitors, and each provides different benefits and usages, so it's important to understand how each works.

Images on OLED will not be distorted from the sides and can maintain their quality and readability from nearly any angle. While the most common LCDs don’t.

The degree of opening (twist) of LC is controlled by adjusting the voltage input. When the opening is large, more light can pass through. Therefore, the amount and brightness of the light are controllable.

Given the assembly structure of the backlight layer to the LCD panel, it is a gap between the screen and the frame to a certain degree.

For your quick knowledge, we have recapped the key differences in the following table, then illustrate them in detail point by point.

Many productivity monitors have USB hubs because of these extra features, and if you want to use a laptop with multiple devices, these monitors are great for you. You can also see our recommendation for the best USB-C monitors.

In addition to the flicker phenomenon, OLEDs will cause more obvious irritation to the eyes and even the migraine after a long-time of watching.

In the electric field effect, the nematic liquid crystal molecules will twist, which can block the light passing through, to control the transmission or shielding of the light source from the backlight.

OLED screens are usually characterized by a wider color gamut offering a richer color spectrum and more natural colors. Although, it is necessary to mention ...

Although the overall share of OLED is not large, due to its unique flexible feature, it can meet the needs of curved and foldable screens and is widely used in fashion and emerging electronic products with a small screen,  such as mobile, smart wearables, and VR devices.

*For USB 3.2 Gen 2, the 20 Gbps transfer speed is only possible over USB-C. USB-A and USB-B ports are limited to 10 Gbps transfer speed.

Common Screen Resolutions for Desktop in 2023 · 1920×1080 (22.18%) · 1366×768 (14.04%) · 1440×900 (6.41%) · 1280×720 (5.45%) · 1280×1024 (4.52%).

However, in 2022 SDI Display Week, Meta introduced their new generation VR headset Quest 2, which uses the fast switch LTPS LCD technology. The image persistence is low and almost not noticeable in VR game playing.

IPS LCD vs OLED vsAMOLED

USB-C encompasses the advantages of both USB-A and USB-B. You can use it for data transfer from compatible devices, and you can use it as an upstream port for the rest of the USB hub. USB-C also delivers power, sometimes at a higher rate than a USB-A port, which means it can be a great choice for charging devices.

Some high-end monitors, like the Dell U2723QE, can have multiple USB-C ports, each with a different purpose. Using the U2723QE as an example, one of its USB-C ports is for the DisplayPort Alt Mode, and it supports 65W of power delivery. Another port is simply for power, with 15W of power delivery. Lastly, it also has a USB-C port used as an upstream port as this monitor doesn't have USB-B, so connecting this port to your computer lets you use the entire USB hub.

Wondering about LCD vs. LED display, which one is better? Check out our guide, you'll learn and choose the right one for your business.

USB-C ports also support higher power delivery than USB-A ports, as they support higher amperage, and a USB-C port can support from 7.5 to 240W of power, depending on its USB version and supported voltage. Most USB-C monitors support up to 96W of power delivery, but those with lower power delivery, like 5 to 15W, aren't ideal for laptops because they won't charge them. Even a monitor of 65W of power delivery isn't enough to charge demanding laptops, like those with dedicated GPU, but it's still fine for tablets or less demanding laptops.

USBs have many different capabilities, and they help us transfer data or power up our devices every day. Getting a monitor with a USB hub is very useful if you want extra USB ports to plug your peripherals in. USB-C ports on monitors are also becoming handy if you want to connect a laptop easily. Different USB versions are available with different transfer speeds and power delivery, and each USB version affects the user experience when connecting your devices to the USB hub on your monitor.

The main advantage of USB-C is its ability to support DisplayPort Alt Mode, but it's important to remember that not all USB-C ports on monitors support it. As the name suggests, DisplayPort Alt Mode is an alternative way of sending video signals via DisplayPort. This means that the USB-C port acts as a video port and supports power delivery and data transfer. You can connect a compatible laptop to your monitor via USB-C to display an image from it and charge it using a single cable - if the monitor supports high-power delivery—without having to plug in an external power cable to the laptop. This is extremely useful as some laptops are cutting their HDMI ports and opting for USB-C ports. Instead of getting a USB-C to HDMI adapter, you can plug the laptop directly in via USB-C.

While different types of USB-B connections have their own advantages and disadvantages, monitors mainly have the USB-B connection that's part of the USB 3.0 specification. Unlike the rectangular shape of USB-A connections, these have unique shapes with nine pins and are only backward compatible when you plug an older cable into this newer port design.

At present, AMOLED is widely used in consumer electronics products and is the main OLED technology on the market application.

The main disadvantage of USB-A is that it isn't reversible, and you can only plug it in one way. It doesn't act as a video port, either. This means you can't directly display an image from a device like a laptop through USB-A. However, remember that this is different than transferring video files, which you can still do with a USB-A port, but that's part of the benefits of data transfer.

According to the data from TrendForce, in 2021, the penetration rate of LCD panels in the smartphone industry is 58%, while AMOLED has caught up and reached 42%, as shown in figure 1.

In this article, we are trying to give you a complete guide to their comparison, so that you can understand their differences and then choose your suitable display technology.

Because, in the terminal usage, the working frequency of each pixel for different colors is unequal, in consequence, the diminution rate is inconsistent.

A flat-panel display that is made of an array of cells containing liquid crystals that align to block or transmit light in response to an electric current.

The main purpose of USB-B ports on monitors is to serve as an upstream port for the USB hub. This means it sends data from the rest of the USB ports to your PC. In other words, you need to connect a USB-B to USB-A cable to connect peripherals like your keyboard, mouse, or memory devices to the USB-A ports on your monitor.

The liquid crystal (LC) is placed between two conductive glasses, when power is applied, the electric field is created between two electrodes.

For example, on OLED TVs, burn-in happens on the blue pixels due to high frequent lighting. However, the white screen of OLED TVs will also change due to blue’s diminishing. If we compare the white screen every month, yellowish will be noticed.

Therefore, the burn-in phenomenon inevitably happens on an OLED screen, more obviously on a big screen, and its average service lifespan is shorter than LCD.

For example, if the 1080p LCD screen is replaced with an OLED screen, it is obvious to see the graininesses on the screen. But when the resolution reaches above 2k, this phenomenon is not obvious anymore.

For the same reason, the flexibility of LCD is limited, it can only be bent to a certain angle. The curved screens of the desktop are LCDs, which are only bent to a small degree.

OLED technology is relatively new and in the developing stage, still has a long way to optimize the technology as well as the production processes and yield rate.

Unlike Type A and Type C connections, a Type B connection on a monitor doesn't act as a host but rather a connector between the devices and the computer. Host connectors, like Type A and Type C, are also powered to directly provide power to your device, whereas a USB-B connection isn't powered. There are USB-B Powered ports with two extra pins, but you don't find those on monitors.

Given the OLED screen is self-illuminating, when watching the screen in a dark environment, the light is strong, which causes more damage to the eyes than the light from LCD.

IPS LCD vs OLEDphone

Even though the general cost of OLEDs is almost twice as much as LCD panels,  OLED panels are still popular in high-end TVs or flagship mobile phones, while LCD panels have occupied the largest share in the whole display market.

However, the PMOLED is still facing the problems of high power consumption and short lifespan. Currently, the common size of the display is limited to around 5-inch.

In comparison, in addition to light and thin features, OLEDs can be folded almost as freely as origami. The foldable smartphone is supported by OLED technology.

Three main types of USB connections are found on monitors: USB-A, USB-B, and USB-C. While USB-A and USB-C connectors haven't changed shape over the years, there are a few different types of USB-B connectors, and monitors generally include the USB 3.0 version of USB Type B. You can see the different shapes below.

You may notice when tilting or viewing an LCD monitor from different angles, images become distorted or lose their colors.

As in OLED, it is PWM (Pulse-Width Modulation) dimming, which means controlling the brightness by continuously switching on and off the screen at a certain high frequency till it is imperceptible by the naked eye.

As the nature of the liquid crystal layer cannot be fully closed, when the LCD panel displays black, some light will pass through the color layer. The black shown on the LCD screen is gray, a combination of white and black.

While there's a lot to learn about USB types, this article focuses on the main types of USB connections with monitors and how they affect the user experience.

Hence, in the low brightness status of the OLED, the screen off time is long, the black field interval become obvious, and the screen on and off (flickers) is noticeable by our naked eyes.

Unlike LCD, when OLED displays black, the pixels in the black area can be directly turned off to achieve an almost pure black effect. In another word, In theory, OLEDs have an extreme contrast ratio.

The OLED screen has almost no smear in normal usage except that the white text will produce the smear on a pure black background.

Of course, for your devices to work at the correct USB specification, the cables must also meet your monitor's USB version. You can't use an old USB 1.0 cable on a USB 3.1 device and expect a 10 Gbps transfer speed. Most monitors come with necessary USB cables, but if you need to buy one for your monitor, it's important to ensure you get the cable for the USB version with which your monitor works.

We test the USB capabilities on monitors with a USB hub. We list how many USB-A, USB-B, and USB-C ports it has and what their advertised transfer speeds are. We also measure the power delivery of the USB-C port with a USB-C power meter. Lastly, we list whether or not the monitor supports DisplayPort Alt Mode through its USB-C port. You can see an example of the test with the Dell U3223QE here.

Another advantage of USB-A is that it offers power delivery. Although limited, it's enough power to charge smaller devices like your phone.

As shown in the previous structure comparison, due to the existence of the backlight layer and liquid crystal layer, the LCD screen is thicker than the OLED.

Another difference between the USB versions is their power delivery, which isn't as straightforward as the data transfer speed. For USB 1.0 and 2.0, the max power output is 2.5W (500mA, 5V), and that increased to 4.5W (900mAm, 5V) with USB 3.0. There are different power specifications part of USB 3.1 and newer, but not all are relevant to monitors, as some have to do with dedicated chargers, which we won't cover in this article.

USB-C is the newest USB connection, and it's the most versatile. It's slowly being implemented on various electronic devices, including mice, laptops, and phones. The ports have a rather simplistic, reversible design, so you don't have to struggle to plug something in.

With the knowledge of how both display technology work and their structures, the differences in features can be easy to explain.

Compared with LCD, the OLED screen is a solid-state component, so it can perform better in anti-vibration and low-temperature resistance (normal low operation temperature is -40 ℃).

Monitors only have female USBs, also called receptacles or ports. A male connection is called the plug and is found on devices or cables.

In screen brightness control, for LCD, it is usual to control the brightness directly by adjusting the voltage of the backlight (DC dimming).

At present, given the technology developed more than 3 decades, LCD technology and supply chain is mature, and new technology and solution are still improving and introduced in the market to keep their advantage.

Each type of USB connection has pros and cons, some of which are listed below, but we'll get into more detail about each type below.

However, a new technology In-Plane Switching (IPS) has compensated for the drawback of LCD, the viewing angle of IPS LCD can even reach 170⁰.

The full form of OLED is organic light-emitting diode, which is an organic self-luminous material that emits light by itself without the need for a separate backlight or color filter. Each OLED pixel can be assigned three colors red, green, and blue.

The color of the USB port is supposed to specify which version it has, but this isn't always 100% accurate. Most monitors have blue or teal ports that support USB 3.0 or 3.1. There are symbols to indicate which type of SuperSpeed of data transfer it supports: there's SuperSpeed with 5 Gbps data transfer on USB 3.1 and 3.2, and SuperSpeed+ supports 10 Gbps of data transfer with a USB-A or USB-B port. As mentioned above, a USB-C port can go up to 20 Gbps with SuperSpeed+. You can see examples of each symbol on a monitor below, with the standard SuperSpeed (5 Gbps) on the left and SuperSpeed+ (10 Gbps) on the right.

On top of supporting DisplayPort Alt Mode, some USB-C monitors like the LG 40WP95C-W support Thunderbolt, which is great if you have a MacBook. This allows for higher data transfer and power delivery than other USB-C monitors that support DisplayPort Alt Mode, as long as you're using a Thunderbolt cable. Thunderbolt 3 and 4 use USB-C plugs, but not all USB-C monitors support Thunderbolt.

However, due to the pixel arrangement of OLED, even if two screens have the same resolution, the clarity of the OLED screen will be lower than LCD.

Each pixel of OLED work individually, the pixels turn off and consume no power at all when displaying black and consume different energy while displaying different colors in different brightness.

To adapt to various requirements in the market, different compensatory technologies keep introduced to the market, such as TFT and IPS.

In fact, in PWM dimming, the screen’s brightness is set and not changed. Instead, the lit time of the screen is changing, for example:

While USB-B ports don't serve as many purposes as USB-A and USB-C ports, like charging or video display, they're still important for monitors because they let you use the other USB ports on your monitor.

Because in a project, except for the technology features, there are still many things that need to be considered, like budget, supply resources, etc.

When the voltage is input, the anode current flows through the device, electron holes are formed. Meanwhile, the cathode injects electrons into the circuit.

USB-A is the most common type of connection, and you likely use it the most. The main advantage of these connections is data transfer, and it's what you'll connect your hard drives and memory sticks to. You can also connect your peripherals like keyboards and mice, and having extra ports on your monitor frees up ports on your PC, which is great if you need to connect many devices.

IPS LCD vs OLEDwhich is better for eyes

USB hubs on monitors connect external devices, like memory sticks, laptops, and phones. A Type A connection is great for data transfer, like from a hard drive or memory stick, while Type B connections are generally for data passthrough. Lastly, USB-C is the most versatile connection that supports features like DisplayPort Alt Mode, as it allows video transfer and is also compatible with Thunderbolt.

According to the data from Frost & Sullivan, in 2020, LCD is the absolute mainstream display panel technology, with shipments accounting for 96% of the global display market share.

In addition, the organic and self-emitting nature of OLED material is sensitive to humidity and oxygen concentration, resulting in some pixels degrading faster (decay period) than LCDs.

The cables you might receive with a monitor are usually USB-B to USB-A, USB-C to USB-C, or even USB-C to USB-A cables. Generally speaking, you shouldn't have to worry about the cable you're using with your monitor as it should come with it, or your devices come with their own cables. However, if you need to buy a cable, you can look at its advertised USB version or the color of its plugs to see which version it supports. You can see examples of different cables below.

Its simple structure is beneficial to the production process and cost management in manufacturing. With the fast response feature,  It has great development potential in microdevices for simple displays.

When both meet in the organic light-emitting layer, they become excitons and release photons. Consequently, colors are displayed on the screen.

This driving mode is easier to achieve high brightness, high resolution, high color performance, and low energy consumption.

If the time takes too long, the pixel will not have time to change from color A to color B when the screen is rapidly sliding. As a result, the image remains and the image smear appears visually.

As to the LCD screen, normally it is hard to eliminate the smear, which is also affected by the temperature. The lower the temperature, the more serious the smear happens.

There are also USB ports with a yellow color that are sleep-and-charge ports. These continue powering up your devices even after the monitor or computer has gone to sleep.
