When it comes to choosing the right display for your HeyKD kiosk, the panel type will significantly impact the overall image quality. The three main panel technologies—TN (Twisted Nematic), IPS (In-Plane Switching), and VA (Vertical Alignment)—each have their advantages and disadvantages. Understanding these can help you make an informed decision that best suits your needs.

TN (Twisted Nematic) Panel

TN panels are commonly found in gaming monitors due to their rapid response time. They offer a ~1ms response time (gray to gray pixel transition, or ‘GtG’ for short), which eliminates ghosting or trailing behind fast-moving objects. When paired with a high refresh rate, TN panel gaming monitors provide a smooth gaming experience at an affordable price.

However, TN monitors have the worst color reproduction and narrow viewing angles (170° horizontally and 160° vertically), which causes the image to shift in color, contrast, and brightness when viewed at skewed angles. They can be quite bright, and more expensive models will have more vibrant colors, but not as good as those of IPS or VA panel alternatives.

IPS (In-Plane Switching) Panel

IPS panels provide the most accurate and consistent colors as well as wide 178° viewing angles, meaning that you can look at the screen from basically any angle without the image shifting in color and contrast. This makes them ideal for designers or photographers.

Most IPS monitors now have just as fast pixel response time speeds as TN panels (~1 ms), though there are still some slower IPS variants with 4 to 5 ms. For many gamers, even these slower IPS panel monitors will provide a satisfactory fast-paced gaming experience, as ghosting is barely noticeable.

The main downside of IPS monitors is ‘IPS glow.’ If you’re watching particularly dark content in a dark room, you will be able to notice light ‘glowing’ around the corners of the screen. This is an expected side effect caused by the excess light passing through the panel.

VA (Vertical Alignment) Panel

VA panels boast a superior static contrast ratio. While IPS and TN panels usually have a contrast ratio of around 1,000:1, most VA panels have a contrast ratio between 2,500:1 and 3,000:1, with more expensive models offering even higher contrast.

However, this also means that pixels take longer to change from such deep blacks to lighter shades. Consequently, in dark scenes, you get noticeable black smearing behind fast-moving objects, which can be distracting for competitive gaming.

OLED Panels

OLED panels are different from IPS, TN, and VA panels because they don’t rely on a backlight to produce an image; instead, each pixel produces its own light. This allows OLED displays to produce true blacks as pixels can completely turn off. They also offer instantaneous pixel response time and don’t suffer from backlight bleeding, IPS/VA glow, blooming, or similar visual artifacts.

However, OLED panels are susceptible to permanent image burn-in and temporary image retention, and they cannot get as bright as some LED-backlit panels.


Choosing the right panel type for your HeyKD kiosk depends on your specific needs and preferences. If you prioritize fast response times and affordability, a TN panel might be the best choice. If color accuracy and wide viewing angles are more important, an IPS panel would be ideal. If you want superior contrast, a VA panel could be the way to go. And if you want true blacks and instantaneous pixel response time, an OLED panel might be worth considering.
