Please note that some of the mentioned types may be considered a sub-category of LED TVs; therefore, some of the names may vary depending on the manufacturer and the market.

Overall, while TN panels are an affordable and fast option, they may not be the best choice for those looking for accurate colour reproduction and wide viewing angles.

An OLED or organic light-emitting diode display isn’t another variation of LED. OLEDs use negatively and positively charged ions for illuminating individual pixels. By contrast, LCD/LED TVs use a backlight that can make an unwanted glow. In OLED display, there are several layers, including a substrate, an anode, a hole injection layer, a hole transport layer, an emissive layer, a blocking layer, an electron transport layer, and a cathode. The emissive layer, comprised of an electroluminescent layer of film, is nestled between an electron-injecting cathode and an electron removal layer, the anode. OLEDs benefit from darker blacks and eschew any unwanted screen glow. Because OLED panels are made up of millions of individual subpixels, the pixels themselves emit light, and it’s, therefore, an emissive display as opposed to a transmissive technology like LCD/LED panels where a backlight is required behind the pixels themselves.

One last word on the size of touch screens: Please note that resistive touch screens don’t exceed 27”; beyond that point, they function poorly.

LCDs have utilized CCFLs or cold cathode fluorescent lamps. An LCD panel lit with CCFL backlighting benefits from extremely uniform illumination for a pretty even level of brightness across the entire screen. However, this comes at the expense of picture quality. Unlike an LED TV, cold cathode fluorescent lamp LCD monitors lack dimming capabilities. Since the brightness level is even throughout the entire array, a darker portion of scenes might look overly lit or washed out. While that might not be as obvious in a room filled with ambient light, under ideal movie-watching conditions, or in a dark room, it’s noticeable. LED TVs have mostly replaced CCFL.

Like TN, IPS or In-plane Switching displays are a subset of LED panels. IPS monitors tend to boast accurate colour reproduction and great viewing angles. Price is higher than on TN monitors, but in-plane switching TVs generally feature a better picture when compared with twisted nematic sets. Latency and response time can be higher on IPS monitors meaning not all are ideal for gaming.

The image quality is top-notch. OLED TVs feature superb local dimming capabilities. The contrast ratio is unrivalled, even by the best of QLEDs, since pixels not used may be turned off. There’s no light bleed, black levels are incredible, excellent screen uniformity, and viewing angles don’t degrade the picture. Unfortunately, this comes at a cost. OLEDs are pricey, and the image isn’t as bright overall when compared to LED panels. For viewing in a darkened room, that’s fine, but ambient lighting isn’t ideal for OLED use.

When manufactured by a reputable, trusted company, both capacitive and resistive touch screen devices will last for a very long time. In fact, most have an average lifespan in excess of a million touches. For the average user, that’s a very long time. With that said, capacitive touch screen devices typically last longer than resistive devices simply because they don’t use pressure to identify touch commands. Without pressure being placed against the interface, capacitive devices are less susceptible to wear and tear, resulting in a longer lifespan.

When it comes to display technologies such as projectors and panels, factors such as resolution and refresh rate are often discussed. But the underlying technology is equally, if not more, important. There are tons of different types of screens, from OLED and LED to TN, VA, and IPS. Learn about the various monitor and television types, from operation to pros and cons!

The most common form of monitor or TV on the market is LCD or Liquid Crystal Display. As the name suggests, LCDs use liquid crystals that alter the light to generate a specific colour. So some form of backlighting is necessary. Often, it’s LED lighting. But there are multiple forms of backlighting.

While there are always exceptions to this rule, most capacitive touch screen devices are made with a glass surface. Resistive touch screens, on the other hand, are made with a synthetic plastic material. Glass allows for the operator’s electrical charge to pass through and into the device, which of course is essential for the overall function of a capacitive device.

They suffer from inferior colour reproduction, meaning that the colours they display may be less accurate and vibrant than other technologies. Additionally, they have poor viewing angles, meaning the picture quality can degrade when viewed from certain angles. This is due to the way the liquid crystal molecules point at the viewer and the orientation of the light polarizers at 90-degree angles.

Please note that some of the mentioned types may be considered a sub-category of Quantum Dot TVs; therefore, some of the names may vary depending on the manufacturer and the market. Also, it's worth mentioning that not all brands use the same technology. Some are using QD films or QD-LEDs, others are using QD-OLEDs, and the list could go on.

LED TVs boast several different benefits. Physically, LED television tends to be slimmer than CCFL-based LCD panels, and viewing angles are generally better than on non-LED LCD monitors. So if you’re at an angle, the picture remains relatively clear nonetheless. LEDs are also extremely long-lasting as well as more energy-efficient. As such, you can expect a lengthy lifespan and low power draw. Chances are you’ll upgrade to a new telly, or an internal part will go out far before any LEDs cease functioning.

Please note that OLED technology can be applied to various displays and devices, and the list mentioned above may not be exhaustive. Also, some types may be considered a sub-category of OLED.

A resistive touch screen has a lower level of touch sensitivity. In other words, you must press your finger against a resistive touch screen harder and more forcefully than a capacitive touch screen. By requiring a more purposeful touch to activate, a resistive touch screen promotes higher input accuracy, makes accidental taps and touches less likely to occur, and lowers the risk of erroneous input commands. The level of touch sensitivity you need is also directly linked to the environment in which the touch screen will be used. For example, a resistive touch screen is the perfect solution on a construction site where water or debris might land on the screen.

The pricing of VA monitors varies, but they are typically more expensive than TN monitors and less costly than IPS or OLED monitors. Overall, VA monitors are an excellent option for those looking for a balance between good picture quality and affordability.

Please note that some of the mentioned types may be considered a sub-category of LCD TVs; therefore, some of the names may vary depending on the manufacturer and the market.

Now that you better understand the various display technologies available, you can make a more informed decision when selecting the best display to fit your needs. Ultimately, the choice depends on specific needs and preferences, including size, resolution, brightness, and colour accuracy.

An IPS display aligns liquid crystals in parallel for lush colours. Polarizing filters have transmission axes aligned in the same direction. Because the electrode alignment differs from TN panels, black levels, viewing angles, and colour accuracy is much better. TN liquid crystals are perpendicular.

On the other hand, capacitive touch screens don’t reflect light. Instead, they maintain a neutral surface when exposed to light, so they don’t create any major or otherwise distracting glare.

While many newer TVs and monitors are marketed as LED TVs, it’s sort of the same as an LCD TV. Whereas LCD refers to a display type, LED points to the backlighting in liquid crystal display instead. As such, LED TV is a subset of LCD. Rather than CCFLs, LEDs are light-emitting diodes or semiconductor light sources which generate light when a current passes through.

It typically costs more to produce a capacitive touch screen device than a resistive device. So, if you’re looking for an inexpensive touch screen device, you may want to stick with a resistive model for this very reason.

LCD is the most common type and uses liquid crystals and either LED or CCFL backlighting. LED TVs are a subset of LCD panels with LED backlighting. TN panels offer a low-cost solution with low response time and input lag, while IPS monitors provide superior colour accuracy and wide viewing angles. VA panels have higher contrast ratios than IPS, but limited viewing angles and OLED TVs offer excellent colour accuracy, infinite contrast ratio, and superior motion handling. QLED TVs use quantum dots to enhance colour accuracy and brightness, making them great for bright rooms.

Both resistive and capacitive touch screen devices are accurate. Of the two, however, the former comes out on top. Resistive touch screen devices offer the highest level of accuracy, with the ability to pinpoint the precise location of your touch commands. Projected capacitive devices come in second, followed by surface capacitive in third place.

QLED TV sets are thus able to achieve many more local dimming zones than other LED TVs. As opposed to uniform backlighting, local dimming zones can vary backlighting into zones for adjustable lighting to show accurate light and dark scenes. Quantum Dot displays maintain an excellent, bright image with precise colour reproduction.

Ultimately, the choice between LED vs VA or any other display technology will depend on your specific needs and preferences, including things like size, resolution, brightness, and colour accuracy.

Resistive touch screen devices are more resistant to water, dust, and debris than capacitive. This doesn’t necessarily mean they’re waterproof (unless stated in specifications). However, you can expect a resistive device to hold uplonger in wet/humid conditions when compared to a capacitive device.

A VA or vertical alignment monitor is a type of LED monitor that features excellent contrast ratios, colour reproduction, and viewing angles. This is achieved by using crystals that are perpendicular to the polarizers at right angles, similar to the technology used in TN monitors. VA monitors are known for their deep blacks and vibrant colours, making them popular for media consumption and gaming.

They also have better viewing angles than TN monitors, meaning that the picture quality remains consistent when viewed from different angles. However, the response time of a VA monitor is not as fast as that of a TN monitor, which can be a concern for those looking to use the monitor for fast-paced action or gaming.

Capacitive touch screenadvantages and disadvantages

The use of multi-touch support allows for greater versatility in terms of control, making it the ideal choice for some industrial and commercial applications. Multi-touch technology can collect multi-point signals at the same time and judge the meaning of each signal, allowing for gesture recognition (like pinching). This is why most smartphones and tablets use projected capacitive screens.

A quantum dot LED TV or QLED is yet another form of LED television. But it’s drastically different from other LED variants. Whereas most LED panels use a white backlight, quantum dot televisions opt for blue lights. In front of these blue LEDs sits a thin layer of quantum dots. These quantum dots in a screen glow at specific wavelengths of colour, either red, green, or blue, therefore comprising the entire RGB (red-green-blue) colour spectrum required to create a colour TV image.

An LCD panel is transmissive rather than emissive. Composition depends on the specific form of LCD being used, but generally, pixels are made up of subpixel layers that comprise the RGB (red-green-blue) colour spectrum and control the light that passes through. A backlight is needed, and it’s usually LED for modern monitors.

As you can see, a wide variety of displays are available on the market today, each with their unique advantages and disadvantages. While many monitors and TVs are referred to by various names, such as LED, IPS, VA, TN, or QLED, many are variations of LCD panels. The specific technology used in a display, such as the colour of backlighting and the alignment of pixels, plays a major role in determining the overall picture quality.

These displays are known for their high refresh rates, ranging from 100Hz to 144Hz or higher. As a result, many monitors marketed towards gamers feature TN technology. The fast response time and low input lag make them ideal for fast-paced action and gaming. However, TN panels have some limitations.

We’re going to get a little bit more technical here. There are two main types of resistive touch screens (4-wire and 5-wire) and two options of technology for capacitive touch screens (surface capacitive and projected capacitive). Among these four types, only one by default supports multi-touch controls: the projected capacitive touch screen. This is in stark contrast to the other devices, which only support single touch. There is one caveat:avcompany has developed a 2-touch resistive controller that only works on 5-wire resistive touch screens.

While capacitive and resistive touch screens have similar pixel resolution, they have different properties when exposed to light. The many individual layers in resistive touch devices make them susceptible to light glare. Whether indoors or outdoors, light will bounce off the top layers of the device to create a blinding glare.

Further segmenting LED TVs down, you'll find TN panels. A TN or twisted nematic display is a type of LED TV that offers a low-cost solution with a low response time and low input lag.

Resistive touch screens and capacitive touch screens support the use of touch commands, but they use different mechanisms to detect them. Resistive touch screens identify the origin of touch by pressing two layers together, whereas capacitive devices work by identifying the electrical charge produced by the operator. Today, we’ll take a closer look at capacitive vs. resistive touch screens, highlighting the key differences between them.
