The flexible liquid-crystal-screen module includes a groove-type middle bezel, a flexible liquid-crystal display and a backlight assembly, wherein, the backlight assembly is fixed at a bottom of a groove of the groove-type middle bezel; the flexible liquid-crystal display is fixed on an opening of the groove of the groove-type middle bezel, and the backlight assembly is spaced from the flexible liquid-crystal display.
In a second aspect, a method of assembling a flexible liquid-crystal-screen module is provided in the embodiments of the present disclosure. The method includes fitting a backlight assembly at a bottom of a groove of a middle bezel; lapping a flexible liquid-crystal display on an opening of the groove of the groove-type middle bezel, the backlight assembly and the flexible liquid-crystal display being spaced from each other.
Accompanying drawings provided herein are used to provide a further understanding of the present disclosure and constitute a part of the present disclosure. Illustrative embodiments of the present disclosure are used to explain the present disclosure, but do not limit the present disclosure. In the drawings:
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are a part, rather than all, of the embodiments of the present disclosure. All other embodiments which can be obtained by a person skilled in the art without paying any creative effort based on the embodiments in the present disclosure belong to the protection scope of the present disclosure.
The technical solutions provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
As shown in
A backlight assembly (Back Light) is an assembly located behind a liquid-crystal display (LCD), and a lighting effect of the backlight assembly directly affects a visual effect of the liquid-crystal display. The liquid-crystal display itself does not emit light, but can display a graphic or a modulation result of light modulated by the liquid-crystal display.
Specifically, the backlight assembly 21 may be fixed to the bottom of the groove of middle bezel 215 by an adhesive 214, and the flexible liquid-crystal display 20 may be fixed to the opening of the groove of the groove-type middle bezel 215 by an adhesive 212, so that the backlight assembly 21 and the flexible liquid-crystal display 20 may be separated from each other without structurally interfering with each other.
In an embodiment, the flexible liquid-crystal display 20 may include a curved-surface cover plate (touch screen) 201, an optical adhesive 202, and an assembly of a curved-surface polarizer and a curved-surface glass, stacked in sequence from top to bottom.
Further, the assembly including the curved-surface polarizer and the curved-surface glass may include, from top to bottom, a curved-surface upper polarizer 203, a curved-surface upper glass 204, a curved-surface lower glass 205, and a curved-surface lower polarizer 206, stacked sequentially. The glass herein can be a liquid-crystal glass which also called an electric control liquid-crystal glass, or an electric control switchable glass, or a switchable glass; the polarizer can be a polaroid, an imaging by a liquid-crystal display must depend on polarized light, and the liquid-crystal display can be provided with a front polaroid and a rear polaroid which are tightly attached to the liquid-crystal glass.
In an embodiment, the backlight assembly 21 may include a backlight reflecting sheet 211, a backlight light-guide plate 210, a backlight diffusing film 209, and a backlight brightness-enhancement film, which are stacked sequentially from bottom to top. The backlight reflecting sheet can reflect light through a back surface of the backlight reflecting sheet. The light-guide plate may be a plate formed of a material of optical acrylic/Poly Carbonate (PC) which has very high reflectivity and does not absorb light; the plate formed of the material may receive light emitted from a lamp and reflect the light, reflected light may be diffused at various angle, and then a reflection condition may be destroyed and the diffused light is emitted from a front surface of the light-guide plate. The diffusing film may refer to a film applied to a backlight assembly. The brightness-enhancement film may be a film or sheet that is applied to the backlight assembly to improve a luminous efficiency.
It should be noted that, in practical applications, a light bar, such as an LED light bar, may be additionally installed at a horizontal parallel position of the backlight light-guide plate 210.
Further, the backlight brightness-enhancement film may include: a backlight lower brightness-enhancement film 208 and a backlight upper brightness-enhancement film 207.
According to the flexible liquid-crystal-screen module provided by the embodiment, the backlight assembly 21 and the flexible liquid-crystal display 20 are spaced from each other, and the backlight assembly 21 is fixed at the bottom of the groove of the groove-shaped middle bezel 215, so that a support in the related art is not required any long to support the backlight assembly 21 and the flexible liquid-crystal display 20 in order to connect the backlight assembly 21 and the flexible liquid-crystal display 20, but the groove-type middle bezel 215 is directly utilized to implement a support function. The area of the backlight assembly 21 is increased under a condition that the size of the groove-type middle bezel is not changed because the support 114 is not required. Moreover, since the backlight component 21 and the liquid-crystal display are spaced from each other, a condition that the liquid-crystal display is unbendable due to limitation of the backlight assembly is eliminated, a planar liquid-crystal display can be replaced by the flexible liquid-crystal display 20 having a curved-surface, display through the flexible liquid-crystal-screen module can be realized on the terminal, and the area of the backlight assembly 21 is increased. Thus, on basis of realizing the flexible liquid-crystal display, the display area which may display contents by the liquid-crystal display is increased, and accordingly, the bezel looks narrower in terms of a display effect.
Corresponding to the above embodiment, this embodiment provides a method of assembling a flexible liquid-crystal-screen module, so as to solve the problem that a liquid-crystal-screen module in the related art cannot display through a flexible liquid-crystal display and the area of the displayed contents is not large, and a display effect of a bezel is difficult to be made narrower. The flow of the method is schematically shown in
Step S11: fitting the backlight assembly 21 at a bottom of a groove of the groove-type middle bezel.
Step S12: lapping the flexible liquid-crystal display 20 on an opening of the groove of the groove-type middle bezel, the backlight assembly and the flexible liquid-crystal display being spaced from each other.

It should be noted that, in practical applications, a light bar may be additionally installed at a horizontal parallel position of the backlight light-guide plate 210, for example, the light bar may be an LED (Light Emitting Diode) light bar.
Further, the backlight lower brightness-enhancement film 208 and the backlight upper brightness-enhancement film 207 may be stacked in this order from bottom to top when the backlight brightness-enhancement film is fitted.
Specifically, a method of assembling the flexible liquid-crystal display 20 may be: stacking sequentially, at the bottom of the curved-surface cover plate 201, the optical adhesive 202 and an assembly of the curved-surface polarizer and the curved-surface glass.
Further, stacking sequentially the optical adhesive 202 and the assembly of the curved-surface polarizer and the curved-surface glass may include: sequentially stacking the optical adhesive 202, the curved-surface upper polarizer 203, the curved-surface upper glass 204, the curved-surface lower glass 205, and the curved-surface lower polarizer 206.
