Disclosed are a display module, a display device and a viewing-angle switching method. The display module includes a backlight module, a display panel, a lower polarizer sheet, a viewing-angle switching element and a transparent cover plate; the viewing-angle switching element and the transparent cover plate are arranged between the display panel and the lower polarizer sheet, and the transparent cover plate is arranged on a side of the viewing-angle switching element that is close to the lower polarizer sheet; the backlight module is configured to supply light that meets a preset condition, the viewing-angle switching element is configured to switch viewing-angle modes of the display module; the viewing-angle modes include; a first viewing-angle mode and a second viewing-angle mode; and a viewing-angle range of the first viewing-angle mode is smaller than a viewing angle range of the second viewing-angle mode.

Display module, display device and viewing-angle switching method

Disclosed are a light guide plate and a display device. The light guide plate includes a flat plate portion and a fixed portion, the fixed portion is arranged around a periphery of the flat plate portion, forms an installation groove for placing optical films in cooperation with the flat plate portion, a surface for forming a bottom of the installation groove in the flat plate portion forms a light emergence surface of the light guide plate; gap structures corresponding to light source particles of a light bar are formed at a first side of the fixed portion, and bottoms of the gap structures form a light incidence surface of the light guide plate which is perpendicular to the light emergence surface; and a surface of the flat plate portion back on to the installation groove forms an installation surface for installing a reflection sheet and the light bar.
