Abstract

The invention discloses a display device and a flattening control method of the display device. The display device includes: a display panel including a first non-bending area, a bending area and a second non-bending area arranged along a first direction; a folding assembly including a first middle frame, a second middle frame and a hinge The first non-bending area is fixed on the first middle frame; the second non-bending area is fixed on the second middle frame, and the hinge part connects the first middle frame and the second middle frame; at least one strain sensing unit , part of the area of ​​the strain sensing unit is located in the non-bending area, and part of the area is located in the bending area; the strain sensing unit includes a resistor, and when the display panel is in a flat state, it can detect whether there is a fold in the bending area through the resistance change of the resistor. A drive assembly, connected with the first middle frame and / or the second middle frame, when there is a crease in the bending area, it can drive the first middle frame and / or the second middle frame to move along the first direction to flatten the fold creases, so as to achieve the purpose of improving the crease of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display device and a flattening control method of the display device. Background technique [0002] With the development of communication technology and social media, new challenges are presented to the function of mobile phones. At present, users pursue large-sized mobile phone screens, aiming to have a better experience in entertainment activities such as games and videos, but carrying large-sized mobile phones brings inconvenience to users. At this time, the folding screen came into being, and the folding area can take into account the user's needs for a large-size display and easy portability. [0003] In the prior art, the display device can be bent along the bending axis, but after the display device is restored from the bent state to the flattened state, there may be creases in the bending area due to the influence of stress, and the existence of the The ...
