Device for fixing quantum strip of display and display

A device (20) for fixing a quantum strip (10) of a display and a display belong to the technical field of liquid crystal display. The device (20) comprises: a main body provided with a cavity for containing the quantum strip (10) therein; a matching surface used for clamping the quantum strip (10), the matching surface constituting at least a part of the peripheral wall of the cavity and being capable of closely joining the outer surface of the quantum strip (10); and a connecting structure for fixing the main body onto the display. The main body may be made of an appropriate material in order to put the quantum strip (10) under physical protection and heat-insulated protection, and meanwhile, the main body is fixed at the fixed position of the display. The display comprises the device. The device and the display can prevent the quantum strip from overturning and translating, in order to avoid a negative impact on the light extraction effect of a backlight, and to ensure the display quality of the display; in addition, the main body of the device plays a role of heat protection by wrapping up the quantum strip.
