This time after iPadmini6 was listed on the market, large-scale mobile phone screens have continued to roll over. The first problem was the previous jelly screen problem, followed by the blurry mobile phone screen, which also made customers very dissatisfied.

Some customers encountered the problem of discoloration and deformation of the mobile phone screen on their new iPadmini machine equipment. When we put pressure on the mobile phone screen of the new generation of iPadmini, bright or discolored spots will occur at specific points on the control panel. This effect will become more pronounced when the tablet displays a dark image or is actually operating in dark mode.

Several customers have the same personal experience. Some people claim that these spots that shouldn't happen also occur on the replaced machines and equipment displayed in the AppleStore.

The modern LCD mobile phone screen is a transmissive design, composed of liquid crystal suspended between polarized glass or other thin film substrates. When the current is increased, the material will align (or more accurately, the liquid crystal changes direction) to allow the light source from the backlight to pass.

However, the structural features of the LCD panel are very susceptible to mechanical equipment, such as lightly pressing the board with any energy. Increasing the immediate working pressure of the display will cause changes in the liquid crystals and their respective alignment in a single resolution, destroying the delicate balance that allows the light source to be transmitted symmetrically. This will cause distortion, discoloration, moire and other effects.

Although it has not been confirmed, the LCD control panel of the iPadmini is likely to be narrower than the internal hardware configuration, so that the light pressure causes the parts to touch the back of the display. According to reports, these "hot spots" are about the same as the sharp edges of the connectors and other protruding parts discovered by iFixit when it disassembled the device recently.

Some Redditors called for the recall of the machine and equipment, although considering that the personal behavior will not have an adverse effect on daily applications, such a situation is unlikely to happen. Apple did not comment on the matter.
