The mobile device thermally insulating protective cover may provide effective thermal protection without sacrificing portability, ease of use, or functional access. The present invention addresses this need by providing a novel solution that combines thermal insulation with physical protection in a form factor suitable for everyday use. The mobile device thermally insulating protective cover may use a combination of passive and active features that allow a mobile device to be cooler when sitting in direct sunlight for prolonged periods of time, preventing a risk of the mobile device being inoperable due to temporary overheating. The inside of the device may comprise cooling channels built into the material, which may also act as shock absorption.

An electronic device includes a display module comprising a display panel emitting light. The display module has a first non-folding region, a folding region, and a second non-folding region defined therein. The folding region is disposed between the first non-folding region and the second non-folding region. A plate has a through-hole defined therein. The through-hole overlaps the folding region in a first direction. In a first region of the plate, a width of the through-hole in a second direction crossing the first direction varies at a first rate along the first direction. In a second region of the plate, the width of the through-hole in the second direction varies at a second rate along the first direction, the second rate is different from the first rate.

Included in the present disclosure is a system, including a screen protector configured to be applied to a first side of a computing device. In some embodiments, the system includes a case configured to be coupled to the computing device in two arrangements. According to some embodiments, in a first arrangement the case is configured to be disposed over the first side of the computing device such that the screen protector is located between an inner surface of the case and the first side of the computing device, the case configured to align the screen protector with at least a portion of a perimeter of the first side of the computing device. In a second arrangement, the case may be configured to be disposed over a second side of the computing device opposite the first side of the computing device.

A glass substrate, a window including the glass substrate, and an electronic device including the window are disclosed. The glass substrate may include a first area where a groove is formed or arranged and a second area substantially continuous with the first area. A difference (CT) between internal tensile stress at a point of a first portion having a minimum thickness and internal tensile stress at a point of a second portion having a maximum thickness may be at most 100 MPa.
