With the development of photoelectric display technology and semiconductor manufacturing technology, liquid crystal display devices (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) with thin film transistors have become more mature, and have been used more and more widely due to their light weight and convenience in carrying.
However, in the related art, the liquid crystal display device includes a liquid crystal having a gyratory effect and two polarizers having a polarizing effect and a polarizing effect, respectively, and the liquid crystal display device can perform normal display due to the combined effect of the liquid crystal and the two polarizers. Each polarizer layer loses 50% of its light, and the liquid crystal loses some of its light, for example, the twisted nematic liquid crystal has an optical rotation effect of only 80% -90% in the saturated state of the liquid crystal display panel. Accordingly, the display device of the related art has poor light utilization and large power consumption.
Referring to fig. 1, fig. 1 is a schematic view of a partial cross-sectional structure of a display device according to an embodiment of the disclosure. The application provides a display device to solve the technical problems of poor light utilization rate and large power consumption of the display device in the related art.

The light conversion layer 40 is disposed between the carrier substrate 10 and the polarizer 20, and the light conversion layer 40 is configured to convert the preset light into polarized light, and the polarized light is at least partially emitted to the polarizer 20. The micro-rotating assembly 50 supports the light conversion layer 40, and the micro-rotating assembly 50 is configured to rotate the light conversion layer 40 to change the direction of the polarized light emitted to the polarizer 20, so as to adjust the light transmission amount of the polarized light passing through the polarizer 20.
In this embodiment, the carrier substrate 10 may be a flexible substrate, and optionally, the carrier substrate 10 may be made of any one or more of the following materials: polyimide, polyethylene terephthalate (Polyethylene terephthalate, PET), polyethylene naphthalate (Polyethylene naphthalate two formic acid glycol estr, PEN), cyclic Olefin Polymer (COP), polycarbonate (PC), polystyrene (PS), polypropylene (PP), polytetrafluoroethylene (PTFE).

The display device 1 further includes the polarizer 20, and the polarizer 20 is used for polarization detection.
The display device 1 further comprises at least one light emitting member 30 and at least one light conversion layer 40, wherein the light emitting member 30 is configured to emit a preset light, and the light conversion layer 40 is configured to convert the preset light into polarized light at least partially directed to the polarizer 20. In this embodiment, the light emitting member 30 is an ultraviolet light emitting member, the preset light is ultraviolet light, and the light conversion layer 40 is configured to absorb the ultraviolet light and emit the polarized light. In other embodiments, the light emitting member 30 may be a visible light emitting member 30, the preset light is visible light, and the light conversion layer 40 is configured to absorb the visible light and emit the polarized light. The light emitting member 30 is taken as an example of the ultraviolet light emitting member, and should not be construed as limiting the present application. The light emitting member 30 of the present application is an ultraviolet light emitting member, the wavelength of the ultraviolet light is smaller than that of the visible light, and the energy of the ultraviolet light is larger than that of the visible light, and the conversion efficiency of the light conversion layer 40 for converting the ultraviolet light into the polarized light is higher than that of the light conversion layer 40 for converting the visible light into the polarized light.
The display device 1 further comprises the micro-rotating assembly 50, and the micro-rotating assembly 50 is used for supporting the light conversion layer 40. The micro-rotation assembly 50 has a size similar to the size of a Pixel (Pixel) in a conventional liquid crystal display.
The micro-rotating assembly 50 is rotatably connected to the carrier substrate 10, and is capable of driving the light conversion layer 40 to rotate relative to the carrier substrate 10. Wherein, the light conversion layer 40 rotates, and the direction of the polarized light emitted by the light conversion layer 40 also rotates.
The direction of the polarized light means specifically a direction in which a line formed in the polarized light extends in a direction perpendicular to the irradiation direction of the polarized light.
The polarizer 20 has a polarizing axis, and when the polarized light is linearly polarized light, an included angle between a line formed in the linearly polarized light and the polarizing axis is different, the transmission amount of the polarized light on the polarizer 20 is also different. The micro-rotation device can drive the light conversion layer 40 to rotate so as to change the included angle between the line formed in the polarized light and the polarized light axis, thereby changing the transmission amount of the polarized light on the polarizer 20, and achieving the effect of adjusting the brightness and darkness of the color of the picture in the display device 1.

Compared with the technical scheme that the liquid crystal display can normally display only by combining the two layers of polarizers and the liquid crystal in the related art, more light is required to be emitted through the two layers of polarizers 20 and the liquid crystal, and more light is lost. The application only needs to set up the one deck polaroid 20, and need not to set up the liquid crystal and also can reach the regulation the colour of picture and the display effect of bright dark depth in the display device 1, light only need go out through one deck polaroid 20, and the light of loss is less, can improve the light utilization rate of display device 1 is poor, and reduces the consumption of display device 1.
Referring to fig. 1 and fig. 2, fig. 2 is a schematic rotation diagram of a micro-rotation assembly according to an embodiment of the present application. Specifically, when the micro-rotation assembly 50 drives the light conversion layer 40 to rotate by a first angle, the direction of the polarized light is perpendicular to the polarizing axis of the polarizer 20, and the transmission amount of the polarized light on the polarizer 20 is a first transmission amount.
When the micro-rotation assembly 50 drives the light conversion layer 40 to rotate by a second angle, the direction of the polarized light is parallel to the polarizing axis of the polarizer 20, and the transmission amount of the polarized light on the polarizer 20 is a second transmission amount, which is larger than the first transmission amount.
Illustrated in a schematic top-down rotation of the micro-rotational assembly 50 of fig. 2, the solid line portion of the micro-rotational assembly 50 rotates a first angle, and the dashed line portion of the micro-rotational assembly 50 rotates a second angle.
When the direction of the polarized light is perpendicular to the polarization axis of the polarizer 20, the amount of the polarized light absorbed by the polarizer 20 is large, and when the direction of the polarized light is parallel to the polarization axis of the polarizer 20, the amount of the polarized light absorbed by the polarizer 20 is small. Therefore, when the micro-rotation assembly 50 drives the light conversion layer 40 to rotate by a first angle, the display brightness corresponding to the micro-rotation assembly 50 is in a dark state, and when the micro-rotation assembly 50 drives the light conversion layer 40 to rotate by a second angle, the display brightness corresponding to the micro-rotation assembly 50 is in a bright state.
Specifically, the light conversion layer 40 is a plurality of nanorods arranged in an array. The direction of the long axis of the nano rod is the direction of the polarized light. In other words, the direction of the long axis of the nanorods is perpendicular to the polarization axis of the polarizer 20, the display brightness of the region corresponding to the light conversion layer 40 is in a dark state, the direction of the long axis of the nanorods is parallel to the polarization axis of the polarizer 20, and the display brightness of the region corresponding to the light conversion layer 40 is in a bright state.
