Perhaps one of the most critical applications of displays is in the medical field. Devices like heart rate monitors, MRI machines, and ventilators rely on screens to provide accurate readings and controls. A burned-in display can lead to misinterpretations, which in turn can have dire consequences for patient care. For instance, if a doctor misreads a vital sign on a compromised screen, it might lead to incorrect treatments or dosages.

Many modern displays include dedicated burn-in prevention features like pixel shifting, screen sampling, logo dimming, and screen timeouts. Enable these modes for maximum protection.

What causes screenburn

"Great monitor for value!...Great monitor for the price! Excellent value. Works well paired with my primary monitor in a dual monitor setup for work-from-home purposes. ...Versatile Monitor...Nice addition to my other monitors. Love the LG Electronics brand, because the provide the best value for the money invested."

"This portable monitor is awesome! I work from home some days and am usually at my desk with a dock and monitors. ...There’s also provide support for the portable monitor. The freestanding, portable monitors that do not attach to the actual laptop in a firm fashion can be quite awkward unless you have a large desk available to you."

The most obvious effect is clearly visible ghost images, logos, status bars burned into the display. This looks highly unprofessional and makes the display unsuitable for public usage.

Such non-uniformity severely affects image quality and is unacceptable for medical, military, aerospace, and other applications requiring consistent pixel performance.

Ensuring the longevity and clarity of displays across various sectors is not just about convenience but also about safety, efficiency, and in some contexts, life and death. Proper preventive measures against image burn are essential.

While no display is immune to potential image retention, there are several strategies you can employ to minimize the risks. Here are some best practices for preventing image burn in mission-critical systems:

Fixed UI elements like vitals, charts. Static diagnostic images from X-rays, MRIs etc. Limited screen positioning flexibility.

Old CRT monitors used cathode ray tubes to direct electrons and illuminate phosphor dots on the screen. Much like plasma displays, static bright imagery would age the phosphors prematurely. This caused visible image retention and burn-in on CRT monitors. Modern CRTs have mostly been phased out due to this limitation.

Regularly incorporating these tests throughout the display’s lifetime will help you show, troubleshoot and resolve any image burn-in issues before they become severe.

For unavoidably static content like airport departure terminals, vary info position regularly. Change layouts, colors, backgrounds and themes periodically.

"Sleek looking monitor for gaming...I've used quite a few different gaming monitors in the past but I've always wanted to try out an OLED monitor to see what all the hype is about. ...Amazing OLED Monitor...[This review was collected as part of a promotion.] Best gaming monitor ever. I've owned multiple gaming monitors. "

Certain industrial display applications tend to be more vulnerable to image burn due to unavoidable static content being shown for prolonged periods. These use cases need extra care and prevention:

"Amazing gaming monitor...Gaming just feels so much better on this monitor. Easy to setup . Overall experience best set of monitors I have owned ( I bought 2 )...Incredible monitor...One of the best oled monitors out there. I've tried basically every monitor on the market, and this is the best I've tried thus far. "

LCD panels use a backlight and liquid crystal cells to control light transmission through each pixel. A voltage is applied across each liquid crystal to twist and untwist it, changing how much backlight passes through.

Medical displays will show banding, contouring, and distortion in MRI, X-ray, and other diagnostic images. Digital menu boards and kiosks will have muddied and distorted graphics and videos. Burned phone status bars will be clearly visible across apps.

Monitor customer experiences closely to detect any image retention issues early. Follow up on complaints of uneven display appearance and artifacts. Proactively test those units for permanent burn-in.

Riverdi emphasizes customization, ensuring products fit specific project needs. They utilize high-quality materials and components, combined with their team’s expertise, to deliver tailored solutions.

Additionally, the backlight itself ages non-uniformly in areas that are constantly illuminated, worsening the burn-in effect.

Specialized test patterns like grid, dot matrix, checkerboards – stress the display in diverse ways to uncover subtle image retention issues. Run these patterns for at least 30 minutes per session.

To prevent the adverse effects of image burn, it’s important to thoroughly test industrial grade displays to detect any retention issues early. Here are some tips for effective display burn-in testing:

"I'm a gamer, mostly single player, not competitive, and even though I have a 27" / 144Hz gaming monitor I'm using this monitor as my main screen for my PC and my PS5. ...Excellent quality, very flexible stand set-up, and great option for those wanting a portable OLED screen."

Burned-in areas have permanently degraded light and color output, with lower luminance and contrast compared to unaffected regions. This results in visible unevenness in solid colors, gradients, and images.

Don’t max out brightness unless absolutely needed. Use brightness controls to keep optimal picture quality at lower luminance levels.

Industrial settings often employ monitors and screens for control panels, machinery interfaces, and monitoring systems. These displays are crucial for the safe and efficient operation of equipment. A burn-in can not only disrupt the readability but can also pose safety risks. If an operator misreads a crucial value on a burned-in screen, it might lead to machinery malfunctions or even accidents.

Image burn occurs due to the fundamental limitations of display technologies like LCD, LED, OLED, Plasma, CRT, etc. Prolonged display of static content results in uneven aging of the light-emitting elements in the screen.

Low image quality due to uneven luminance and distortion makes digital signage, kiosks, HMIs and medical displays frustrating to use. Customers will associate these negative experiences with the vendor/provider’s brand.

Prolonged high brightness on select areas of the screen degrades the phosphor coatings faster, while dim areas keep their original luminance longer. This luminance difference creates a permanent burn-in.

Displaying alternating high contrast images can help bring out barely noticeable ghost images. Switch repeatedly between all black and all white screens to identify regions with uneven luminance.

Medical displays and airline HMI systems may show burned-in patient vitals, charts, and maps. Kiosks and menu boards keep menu layouts, pricing, and labels. ATM displays show account info and selection bars.

Such artifacts are unacceptable for commercial systems expected to deliver high image quality 24/7. Customers will perceive such displays as defective and low-grade.

Image burn-in is still an ever-present threat for industrial displays used in mission-critical applications where static content cannot be avoided. This guide covers everything related to display burn-in – what causes it, its impacts, how to test for it, and most importantly, best practices to minimize and prevent permanent damage.

After prolonged use of static content like POS or medical displays, run image burn tests to find any retention. Avoid further use until the display passes burn-in tests.

Riverdi supports a variety of third-party tools to facilitate the development process. This includes GUI building tools, development boards, compilers, and more, such as the EVE Screen Designer from Bridgetech and the Riverdi click from MikroElektronika.

Image burn on OLED displays, each pixel has its own organic light-emitting diodes that illuminate to form the image. When a static UI element or logo is persistently shown in the same area, those specific OLEDs age faster than the rest of the display. This results in visible discoloration in the form of brighter or dimmer patches.

This can lead to dangerous operational situations where users cannot fully rely on display visuals. Permanent image burn therefore raises significant safety concerns for many mission-critical industrial display applications.

"Mid-tier 4K gaming monitor with mediocre HDR...But I was looking hard at some of those FALD monitors, but decided they were too expensive. This monitor has terrible HDR compared to OLED or FALD monitors because the blacks are just a dark grey, but other than that, this has excellent brightness (~500 nits) compared to other non-FALD monitors. ...Whether you're a gamer, content creator, or professional, this LG monitor is versatile and a worthwhile investment for an enhanced computing experience."

For such use cases, make sure to employ all the burn-in mitigation strategies mentioned in this guide. Perform more frequent burn-in testing on higher risk deployments. Keep backup units ready in case displays need to be pulled out for image retention remediation procedures.

Image burn has several detrimental effects on digital signage, HMIs, medical displays, and other industrial grade screens where static content cannot be avoided.

Encourage varied display usage with changing imagery. Frequently alter positioning in different orientations. Mix up content types.

Play back test videos with high contrast scenes like night sky, cityscapes, space nebula, etc. Scan the display closely for any visible artifacts, banding or distortion that move with the video.

Avoid fixed UI elements like persistent status bars. Use rotating animations for icons and buttons. Keep onscreen logos/text/graphics small and reposition them often.

"This is one of the best things that could have happen to laptop users especially those of us that were dragging around an extra monitor while traveling. The sidetrak monitor is that answer to the have to have two monitors crowd. ...Love the monitor, not the cords...If the cords were more flexible, this would improve the functionality greatly. "
