Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that the defect of the existing curved surface display device is at least that, due to the spacer provided between the backlight module and the display panel, the thickness of the display device is relatively thick, which affects the visual effect; in addition, the current When the curved display device is displaying, the light source emitted by the backlight module is a flat light source, which does not match the curved display panel, so it will affect the curved display effect

Abstract

The embodiment of the invention relates to the technical field of display, and discloses a backlight module and a display device. The backlight module comprises a back plate capable of elastically deforming, a memory structural element connected with the bottom wall of the back plate, and a printed circuit board. An electric heating wire is arranged in the memory structural element. The two ends of the electric heating wire are electrically connected with the printed circuit board to form a heating loop. By means of the technical scheme, the thickness of the display device can be reduced, and the cambered surface display effect of the display device is improved; furthermore, cambered surface display and plane display can be converted, and the application occasions of the display device are enriched.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, and occupies a dominant position in the current flat panel display market. status. [0003] Currently, curved display has become a new development trend of display technology. In the prior art, in order to realize the curved surface display of TFT-LCD, spacers of different heights are usually set between the backlight module and the display panel, and the display panel is bent to a certain arc by controlling the height distribution of the spacers, thereby realizing Surface display. [0004] In the process of realizing the present invention, the inventors found that the defect of the existing curved surface d...
