Disclosed are a display screen and a display screen frame. The display screen includes a display screen frame and a plurality of display modules, the display screen frame includes a plurality of profile rods, the plurality of profile rods are distributed at a preset distance interval, an open slot on a same side surface of each profile rod is provided with a magnetic adsorption piece, and the display module is fixed on the magnetic adsorption piece.

A multi-layer bezel for a flexible information handling system (IHS) display may include a die-cut polycarbonate rectangular frame layer, a die cut low durometer foam layer, aligned with and disposed below the polycarbonate rectangular frame layer and a polymer layer aligned with the polycarbonate rectangular frame layer. In various implementations the rectangular frame layer may have a first open-sided rectangular frame segment and a complementary second open-sided rectangular frame segment. The die-cut polycarbonate may be transparent and back-printed with sensor openings for IHS components. The bezel may be a multi-layer stack-up that is die cut to define the bezel. Alternatively, the bezel may be defined by a domed polyurethane upper layer disposed on the die cut polycarbonate rectangular frame layer on a side of the polycarbonate rectangular frame layer opposite the die cut low durometer foam layer.

The present disclosure provides a frequency converter. The frequency converter includes a box body and a bottom box. A bottom portion of the box body is fixedly connected with a top portion of the bottom box. A top portion of a left side of the box body and a bottom portion of the left side of the box body are fixedly connected to a respective fan. A top portion of a left side of an inner wall of the box body and a top portion of the left side of the inner wall of the box body are fixedly connected to a respective annular plate. One end of an output shaft of each fan is fixedly connected to a rotating rod. One end of each rotating rod away from the fan passes through the box body and extends to an interior of the box body.

The present disclosure relates to the field of display technology, and proposes a flexible display device. The flexible display device includes: a housing, with an opening provided thereon; a winding shaft, arranged in the housing; a flexible display panel, having one end connected to the winding shaft, and an opposite end extending out of the housing through the opening; a support member, having one end connected to the winding shaft, and an opposite end extending out of the housing through the opening, wherein the support member includes a plurality of support bars arranged side by side, and a length direction of the support bars is consistent with an axial direction of the winding shaft, and each of the support bars is provided with a through hole, and the through hole penetrates two end faces of a width direction of the support bars; a plurality of moving members.

A display device includes a main body configured to have a display module to which a user interface is output, a bending module located at a center of a back surface of the main body, and a controller. The controller controls the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature, wherein the second curvature is a maximum curvature of the display module.
