First embodiment

During the unfolding process of the flexible screen of the scroll display screen assembly, the unfolding size of the flexible screen needs to be calculated so as to display images in the unfolding area of the flexible screen. If the calculation of the unfolding size of the flexible screen is inaccurate, a black screen may appear when an image is displayed in the unfolding area of the flexible screen, so that the display effect of the flexible screen is affected.

Based on this, this application provides a display screen subassembly to solve the big technical problem of the expansion size calculation error of flexible screen.

In the present embodiment, please refer to fig. 3 and 4, a display screen assembly is provided, which includes a reel mechanism 1, a flexible screen 2, at least one marker 3 and a detecting element 4; optionally, the flexible screen 2 is wound on the reel mechanism 1, and the reel mechanism 1 rotates to drive the flexible screen 2 to expand or contract; the mark body 3 sets up on flexible screen 2, and flexible screen 2 drives the mark body 3 and produces the removal for detecting element 4, and detecting element 4 is used for detecting the mark signal that mark body 3 launched.

Optionally, the marker 3 is disposed on the flexible screen 2, so that the marker 3 and the flexible screen 2 have the same motion state, and the flexible screen 2 drives the marker 3 to move relative to the detecting element 4.

Alternatively, the detecting member 4 is used to detect a marker signal emitted from the marker body 3 to calculate the displacement of the marker body 3 relative to the detecting member 4 from the marker signal.

The marker 3 of the embodiment is arranged on the flexible screen 2, and the unfolding size of the flexible screen 2 can be calculated through the displacement of the marker 3 relative to the detection piece 4, so that the calculation accuracy of the unfolding size of the flexible screen 2 is improved.

In an embodiment, the winding shaft mechanism 1 may include a winding shaft and a driving member, the flexible screen 2 is wound on the winding shaft, an output shaft of the driving member is connected to the winding shaft to drive the winding shaft to rotate through the output shaft of the driving member, and then the flexible screen 2 is wound on the winding shaft through the rotation of the winding shaft. Optionally, the flexible screen 2 can be driven to be unwound through rotation of the reel, so that conversion between two existing states of winding the flexible screen 2 on the reel and unwinding the flexible screen from the reel is realized.

According to the embodiment, the unfolding size of the flexible screen 2 can be calculated through the number of the mark bodies 3 passing through the detection pieces 4 and the mark signals detected by the detection pieces 4, so that the calculation is simplified, and the calculation accuracy of the unfolding size of the flexible screen 2 is improved.

In an embodiment, the distance between the edge of the flexible screen 2 and the detecting element 4 may be the same all the time, and the distance between each marker 3 and the edge of the flexible screen 2 is the same, so that the marker signals emitted by the markers 3 detected by the detecting element 4 are the same, the markers 3 may be conveniently arranged on the flexible screen 2, the calculation may be simplified, and the calculation power resources may be saved.

In one embodiment, as shown in fig. 3, the size and/or shape of the markers 3 are the same, so that the marker signals emitted by the markers 3 are the same, and the size and/or shape of the markers 3 are prevented from affecting the detection accuracy of the detection member 4, so as to improve the calculation accuracy of the expansion dimension of the flexible screen 2.

In one embodiment, the tag body 3 has magnetism, and the detecting member 4 is a hall element, which can detect the magnetic field and its variation. Since the label 3 has magnetism, the label 3 forms a magnetic field around it; when the flexible screen 2 is wound or unwound, the magnetic marker 3 moves along with the flexible screen 2 to generate displacement. The detection piece 4 can detect the change of the magnetic field based on the Hall effect, and calculate the displacement generated by the marking body 3 according to the change rule of the magnetic field so as to calculate the unfolding size of the flexible screen 2; alternatively, the magnitude of the magnetic field strength generated by the marker body 3 may be identified by the marker signal.

Alternatively, the fixed screen 5 may be integrally connected to the unfolded end of the flexible screen 2, or the fixed screen 5 may be spliced to the unfolded end of the flexible screen 2. Alternatively, the fixed screen and the flexible screen may be integrally displayed when the flexible screen is unfolded.
