I fear your issue is not unique to the M series model All laptops have a physical weakness!

The Display is a plate of glass and just like a window pane it doesn’t take much for it to be damaged! The risk is people forget they have a book or some hard object sitting on the lid pressing down and when something or someone sits directly on the system or the on the bag which has both objects the display gets damaged.

I would say about a third of the display issues I’ve seen can be traced to compression damage or physical bang/drop breaking the fragile electrical traces within the panel, requiring the replacement of the display assembly.

You obviously don’t know how displays work. There are no “fragile electrical traces” within a display. This issue is usually caused by the display connector cable becoming loose or damaged.

Jeremy Day, no need to be insulting; @danj's answer was correct. There are indeed electrical traces within a display; how else does the signal to light up an individual pixel get from the edge of the screen to the pixel itself? Any flexing of the glass those traces sit on can break those traces and cause functional issues with the display.

@dadibrokeit - Thanks Jerry!

@Jeremy Day - Here's how it works Liquid-crystal display focus on how the electrodes work and how they are wired to the T-CON unit which controls the powering of the thin film transistor (often called TFT) which in turn causes the nematic liquid crystal to alter its state for that given pixel.
