You can usually get replacement screens from eBay and Co. for relatively little money. The problem with self-repair is that it’s usually very difficult, especially in the case of the screen. Even experts who study iFixit regularly have trouble with it over and over again, as you usually have to “dial” your way through the entire device.
And even if you’ve made it to the panel, the issues aren’t necessarily irrelevant. Because with a touch display module (TDM), the associated controller must also be recalibrated and this is not easily possible. According to Windows United, Microsoft wants to fix exactly this problem.
A patent filed in February and published last week states that in the event of TDM failure or damage, the device must either be shipped or disposed of, precisely because the replacement module cannot simply be recalibrated.
Different IDs trigger a recalibration
Microsoft would like to solve the problem with an ID number: the TDM needs to get a unique ID, so the device will know (via a second ID stored locally) when the touch display module has been replaced. Calibration is then triggered. Then the two numbers are reset or adjusted to each other so that the process can be repeated if necessary.
As is customary in such cases, the patent application does not mention a specific field of application or device, but it is obvious that such a solution would offer many advantages, especially in companies with (many ) touch surface devices, as repairs would be faster. and easier to do on the spot.
