Fixing Burn-In
OLED displays have a number of qualities that make them inherently superior to LCD displays, among them high contrast and response time, however these distinct improvements come with a price, burn-in. OLED materials have a finite lifetime and that lifetime is a function of how much a pixel or sub-pixel is ‘used’, meaning ‘on’. When OLED displays are showing normal content, the images and therefore the brightness of each sub-pixel changes constantly. Each sub-pixel therefore ages at an ‘average’ rate. However when an image, such as a logo remains located in the same position for an extended period, such as on news content or gaming, those pixels stay on at a high level of brightness and age more quickly than others. As they age, the OLED material loses its ability to respond fully and those areas retain part of the image regardless of what is one the screen.
In order t compensate, OLED TV designers have come up with a number of schemes to reduce or eliminate burn-in, with the most common being a periodic shift of the image by one pixel. Given the number of pixels on an OLED TV, this is not noticeable to the user but will move the aging of each pixel closer to the average and reduce potential burn-in. Unfortunately if there is static imagery on the display OLED displays will burn-in as they age, perhaps to a lesser degree with shift compensation, but the materials are finite, so if you use your OLED smartphone for something that causes burn-in, like gaming, you could face some ghostly images as the phones ages.
Rather than live with OLED burn-in issues or having to buy another phone, there is a fix available from a small Canadian company (80mi from Niagara Falls) that has created a device that can fix burn-in on smartphones. The company, IGNIS Innovation (pvt), has released a portable device that can reduce burn-in on OLED smartphones to an imperceptible level in about 90 seconds. The system is based on the company’s algorithms that measure the characteristics of every sub-pixel in the phone’s display and sets up a ‘compensation table’ to adjust the brightness of each. The table acts as an add/subtract number for each pixel that brings areas that have been burned-in back to normal and adjusts the overall display to a uniform brightness for each of the three primary colors.
Using the IGNIS device, a burned-in device can be repaired quickly by local or brand repair shops, although we do not yet have the cost of the unit. The company says the platform and the technology is scalable which means it should be able to perform the same functions for OLED notebooks and monitors, and eventually for OLED TVs. While the adjustment made by the IGNIS device will compensate for the burn-in, more typical repairs would be the replacement of the screen, depending on how severe the issue has become. Under Samsung’s (005930.KS) direct replacement program screen replacement can be an expensive proposition, ranging from $549 for the Galaxy Z Fold 2 (Inner Screen) to $79 for the Galaxy A01, representing 37.9% and 53% of the selling price respectively as quoted by Samsung, so pricing for burn-in repair would likely be a subset of the full screen price.
