The left shell and the right shell of the inward-folding flexible screen mobile terminal and the left shell and the right shell of the outward-folding flexible screen mobile terminal are connected through hinges, and the inward-folding flexible screen mobile terminal can be folded and flattened (180 degrees) and can not rotate towards the reverse folding direction after being flattened, namely the outward-folding flexible screen mobile terminal can not perform outward-folding movement, and the outward-folding flexible screen mobile terminal can not perform inward-folding movement.
The report that the mobile terminal of the flexible screen can be folded inwards and outwards is that the mobile terminal can be opened from a folded inwards state to a flattened state and can be opened to more than 180 degrees continuously, for example, the mobile terminal can be opened to 300 degrees or folded outwards. However, for the inward folding part, the inward folding flexible screen mobile terminal can only realize U-shaped folding, so that when the inward folding flexible screen mobile terminal is folded inwards, a wide gap is formed between the folded left and right shells, and the attractiveness is affected. If the inward folding part realizes the drop-shaped abdication to realize that the left and right shells have narrower and equal-width slits when being closed, the left and right shells are required to have sliding strokes at present, but for a large-size flexible screen translation moving terminal, the large-stroke sliding is difficult to realize under the condition of outward folding, the application of the inward folding function in the large-size flexible screen translation moving terminal is influenced,
