Embodiment Construction

[0053] In order for those skilled in the art to better understand the technical solution of the present invention, a backlight module, a display module, a display method thereof, and a display device of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] At present, most of the double-sided screen display products are simple superposition of two independent display modules, such as figure 1 shown; or, use the light emitted from the hollow area on the back of the first display module to light up the second display module, such as the brand logo.

[0055] figure 1 In terms of thickness and cost, the double-sided screen display product is actually a superposition of two independent display modules. The two independent display modules each include a backplane 1 and a reflective sheet 17 sequentially arranged on the bottom wall of the backplane 1. , light guide plate 3, optical film group ...

Abstract

The invention provides a backlight module, a display module, a display method of the display module and a display device. The backlight module comprises a back plate, a light bar, a light guide plate, a first optical film group and a second optical film group, wherein a light-emitting surface of the light bar is opposite to at least one side edge end surface of the light guide plate; the light guide plate, the first optical film set and the second optical film set are stacked, and the light guide plate is located between the first optical film group and the second optical film group; the back plate comprises a first supporting part, a second supporting part and a third supporting part, and the first supporting part, the second supporting part and the third supporting part are connected in sequence; the first supporting part is used for wrapping and supporting an edge of the first optical film group; the second supporting part is used for supporting the light bar; and the third supporting part is used for wrapping and supporting an edge of the second optical film group. The backlight module is advantaged in that overall thickness and the cost of the backlight module are reduced.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a backlight module, a display module, a display method thereof, and a display device. Background technique [0002] With the continuous development of display technology, there are more and more application scenarios for display screens. As a new display mode, double-sided screen display can realize different display images on the front and back of the same display module. It has a wide range of application scenarios and novel effects. [0003] At present, the double-sided display / double-sided screen display on the market is still in the innovative application stage, and the secondary screen of most double-sided displays is only used to illuminate the brand logo of the terminal product, or realize simple animation display. For these display applications, there is still a lot of room for optimized design in terms of thickness, light effect, display quality, and other...
