Abstract: A reflective sheet, a backlight module and a display screen. The reflective sheet includes a first sheet body disposed between a light guide plate and LED light sources, a second and a third sheet bodies respectively formed by bending and extending from upper and lower edges of the first sheet body, a fourth sheet body formed by bending and extending from an edge of the third sheet body. The first, the third and the fourth sheet bodies are enclosed commonly to form a receiving slot where the LED light sources are disposed. The first sheet body has multiple light transmitting holes such that lights of the LED light sources can enter the light guide plate. A surface of the first sheet body except the light transmitting holes can reflect lights leaked from gap regions among the LED light sources back to the light guide plate to increase light utilization rate.

Abstract: The present invention provides a backlight module and an assembly method thereof. The backlight module is structured such that a first double-sized adhesive tape (10) that adhesively bonds a light-source flexible circuit board (5) and a light guide plate (3) is extended in length thereof so that the first double-sized adhesive tape (10) adhesively bonds a diffuser plate (61), the light-source flexible circuit board (5), and the light guide plate (3) together. In comparison with the prior art, the fixation of the diffuser plate (61) can be achieved without adding a connection member and can effectively prevent sliding of the diffuser plate (61) to cause abrasion with the light guide plate (3) that affects optical taste of backlighting and has a simple structure and reduced manufacturing cost. The assembly method of the backlight module allows for easy and efficient completion of the assembly of the backlight module so that the manufacturing cost is reduced and the production efficiency is high.

Abstract: The curvature remotely adjustable curved-surface display device of the present invention has a remotely controllable motor, an active rod, and a slave rod deployed therein. The active rod has a gear and the first slave rod has a rack bar. When receiving a remote control signal transmitted from a remote terminal, the remotely controllable motor can actuate the gear on the active rod to rotate such that the active rod and the first slave rod move close to each other or away from each other. Such a process applies forces to the display panel, thereby carrying out remotely controlling the curvature of the display panel.
