Description

Display and Fixed Structure

The disclosure relates to a display and a fixing structure applicable to consumer electronic products such as the display.

A general display, especially a computer screen, often includes three parts: a display device, a stand, and a base. The display device is the main body of the display and is used for displaying images. The bracket allows the user to adjust the inclination angle of the display device to achieve the most suitable angle for the user. The base is used to support the machine table to prevent the monitor from tipping over.

Since the main function of the base is to support the machine platform, in accordance with safety regulations, there is a requirement for a 10-degree platform (that is, the shaking range without tipping reaches 10 degrees). As the size of the display device becomes larger, the size of the base also becomes larger. Nevertheless, environmental and external factors may still cause the display to fall, and the display may even fall to the ground if there is no barrier such as a partition wall behind it. This may result in damage to the display or even injury to personnel.

The present disclosure provides a display and a fixing structure applicable to the display, for reducing the possibility of the above-mentioned problems.
