Color Reproduction: IPS panels are known for their excellent color reproduction. If your display shows vibrant and accurate colors, it’s likely an IPS panel. On the other hand, if the colors appear washed out, especially when compared to an IPS display, your panel is likely a TN.

Use Software: Some software can help identify your display panel type. For example, programs like AIDA64 can provide detailed information about your display, including the panel type. However, keep in mind that the accuracy of this information depends on the correctness of the data provided by the display manufacturer.

The light from an LED is emitted from an electrical current going through an organic compound. That organic compound is sandwiched between a positively charged anode and a negatively charged cathode. The cathode is rich in electrons, and the anode is rich in electron "holes". Electron holes are areas in an atom where there is no electron.

In the realm of display technologies, two types often stand out: IPS (In-Plane Switching) and TN (Twisted Nematic). Each has its unique characteristics, advantages, and disadvantages. But how can you tell which one your display uses? This blog post will guide you through the process of determining whether your display panel is IPS or TN.

OLED displays can also produce images with higher contrast than the other two technologies. Since all of the OLEDs on the panel can be turned on and off individually, darker areas of the display can go as dark as they need to.

LCD stands for "liquid crystal display". The early roots of LCD displays stretch back to 1888 when German scientist, Friedrich Reinitzer, discovered an odd substance. It was a liquid that had the molecular structure of a solid. It was later named "liquid crystal."  After decades of study, someone eventually saw the potential for this strange substance to be used for displays.

A display is usually judged by its ability to create vibrant colors. This is an area where OLEDs come out on top. Compared to OLED displays, LCD displays often appear washed out and not as saturated. This is why OLED displays are becoming more popular in the smartphone market.

So, when it comes to OLED vs. LCD—or OLED vs. LED—what are the differences? Here's a look at these three display technologies, what makes them different, and which one is the best.

Professional Evaluation: If you’re still unsure about your display panel type after trying the methods above, consider seeking a professional evaluation. A professional can use specialized tools and their expertise to accurately determine your display panel type.

When a voltage is sent through the layers, the electrons and holes migrate toward one another. The holes travel from the anode and they cross the conductive layer, a layer of organic plastic compound that's good at transporting holes.

Next, the light passes through a transparent electrode. The electrode is necessary for the current to pass through the liquid crystal. After the electrode, there's a horizontal polarization filter. Since the light is vibrating on the horizontal plain, it can pass through unphased.

Response Time: While this method is less definitive, it can provide a clue. TN panels generally have faster response times than IPS panels. If your display has a response time of 1ms, it’s likely a TN panel. However, some modern IPS panels also offer fast response times, so this method should be used in conjunction with others.

Full array LED displays come in right behind OLED displays because, like in the case of OLED displays, the LEDs in an LED display can be controlled individually. Full array LED displays use a method called "local dimming", a technique of shutting off LEDs completely in areas that are darker.

When they meet the electron holes, they have to lose that excess energy in order to relax to the ground state for that atom. They release that energy in the form of photos (light particles). From there, the light travels through the red, blue, and green sub-pixels, just like with an LCD display.

OLED stands for "organic light emitting diode." During the 1970s, scientists were experimented with organic materials that can emit light. In 1987, scientists at Eastman Kodak developed an OLED display that consumed a low amount of energy. And in 2007, Sony unveiled the world's first OLED television: the Sony XEL-1.

Before we delve into the identification process, it’s crucial to understand what IPS and TN panels are and how they differ.

The direct-lit arrangement can appear to be similar to full array, but there are some differences. With the direct-lit arrangement, the LEDs are also dispersed evenly throughout the panel, but there are far less of them. Because of this, direct-lit displays can not do local dimming. This arrangement is present on lower-end devices.

Viewing Angles: Another way to identify your display panel type is by checking the viewing angles. IPS panels maintain color accuracy and image clarity even when viewed from extreme angles. In contrast, TN panels will show significant color shifting and degradation in image quality when viewed from the side.

TN (Twisted Nematic) Panels: The TFT TN panel, on the other hand, is recognized for its fast response times, making it the preferred choice for competitive gaming. However, they have poorer color reproduction and narrower viewing angles compared to IPS panels.

Remember, whether a display panel is IPS or TN does not necessarily determine its quality. Each type has its strengths and weaknesses and is suited to different uses. Therefore, it’s essential to choose a display panel type that best fits your needs, whether it’s for professional use, gaming, or general use.

LCD displays come in last place because in order for any pixels to be visible, the entire back panel has to be lit. This means that completely black areas are impossible to achieve.

When it comes to power consumption, OLED scores a win. Since the OLEDs are powered individually, the display only gives power to the ones that need it. Pixels can be turn off completely when there are blacks in the picture.

The light travels through a vertical polarization filter. Only light vibrating on the vertical plane can pass through the filter. The polarized light then passes through a transistor. The transistor is responsible for applying current to the liquid crystal layer.

Determining whether your display panel is IPS or TN can be a bit tricky, especially if you’re not familiar with the technical aspects of display technologies. However, by using the methods outlined in this blog post, you should be able to identify your display panel type with relative ease.

Manufacturer’s Specifications: The easiest way to determine your display panel type is to check the manufacturer’s specifications. This information is usually available on the manufacturer’s website or in the user manual. Look for terms like “IPS” or “TN” in the display or screen section.

LED displays are virtually indistinguishable from LCD displays. The only difference is in how the two types of displays get their light. Instead of using a translucent sheet, LED displays use individually LEDs. There are three primary arrangements of LEDs in the displays.

OLED displays are for those who want the best of all worlds. They produce the best contrast with the most vivid colors. You will be paying the most for the actual device, but the more power efficient display technology will help even out some of that cost.

After the filter, the light gets its color by passing through the red, blue, and green filters of the sub-pixels. From there, the light exits the display and creates the image that the viewer sees.

Full array LED displays come in second place because of the local dimming functionality. Certain LEDs can be completely turned off when the scene calls for blacks. Even though they have this feature, more energy is consumed per LED because the light has to pass through all of the layers of the LCD before reaching the viewers' eyes.

The first LCD displays to be used on consumer devices were on digital clocks back in 1968. The technology developed over the following years, being put into numerous other devices.

On the other side of the OLED, the electrons flow from the cathode. The electrons then flow to the emissive layer, where they meet the holes. Since the electrons are sent through a voltage, they are "excited", meaning that they have an excess of energy.

The liquid crystal layer is next. The current that's generated by the transistor causes the molecules in the liquid crystal to twist 90 degrees. When the molecules are twisted, the polarized light that passes through gets rotated 90 degrees, now vibrating on the horizontal plain.

LCD display panels are divided into layers. The backmost layer is a light source. This is a translucent sheet that disperses light from bulbs at the bottom of the display.

Chances are, the screen that you're reading this article on is either an LED, OLED, or an LCD display. These are just three of the many display types out there in the wild. On the surface, they all seem the same. But deep down, they couldn't be more different.

Each display technology has its benefits and its drawbacks. LCD displays are for people who want to save more money, while LED displays are for people who would like to spend more for a bit more contrast in their picture. You'll spend more on the TV, but it will have a less significant impact on your electricity bill.

Either way you slice it, if you choose the right manufacturer, you will have a great viewing experience no matter what the technology.

In terms of price, LCD displays are typically cheaper. High definition LCD displays can run you no more than a few hundred dollars. Since LED displays offer better contrast over LCD, you can expect there to be an added price premium.

Full array LED displays have the LEDs arranged evenly throughout the display. This is the preferred arrangement on higher-end TVs. There are a lot of LEDs behind the panel, which means that local dimming is possible.

LCDs are the least power efficient. Regardless of the presence of blacks in the scene, the entire panel needs to be lit. This means that the light source is shining at 100% the entire time.

IPS (In-Plane Switching) Panels: The IPS display panel is known for its superior color accuracy and consistency, as well as its wide viewing angles. They are ideal for professional use where color precision is crucial, such as graphic design, photography, and video editing.
