The embodiment of the invention provides a display. The following are detailed below.

An embodiment of the present invention provides a display device, which is shown in fig. 1 and 2, and includes:
a display unit 10; for displaying pictures for viewing by a user;
a backlight module 30; for providing a light source for the display unit 10;
the light adjusting film 20 is arranged between the display unit 10 and the backlight module 30;
the light adjusting film 20 includes a plurality of light adjusting regions a capable of adjusting light independently.
Specifically, the light adjusting film 20 is divided into m rows × n columns of rectangular regions each of which is one light adjusting region a in the manner shown in fig. 2. It should be understood that the dimming area a may also be square or triangular, and in one embodiment of the present application, the dimming area a is rectangular.
The independent control that this application embodiment was carried out through each light modulation area A need not set up the light source that the light and shade degree is different in backlight unit 30, when improving display device contrast, has simplified display device's structure and has reduced display device's structure.
In some embodiments of the present application, light adjusting film 20 comprises: a first substrate 21 and a second substrate 22 disposed opposite to each other, and a polymer liquid crystal layer 25 between the first substrate 21 and the second substrate 22; here, the first substrate 21 and the second substrate 22 are both PI films (polyimide films), and it should be understood that the polymer liquid crystal layer 25 is encapsulated by an encapsulation adhesive at both ends of the first substrate 21 and the second substrate 22.
In some embodiments of the present application, the polymer liquid crystal layer 25 is a polymer dispersed liquid crystal layer or a polymer stabilized liquid crystal layer. The polymer dispersed liquid crystal layer comprises Polymer Dispersed Liquid Crystal (PDLC), and the polymer stabilized liquid crystal layer comprises Polymer Stabilized Liquid Crystal (PSLC); the Polymer Dispersed Liquid Crystal (PDLC) is a liquid crystal droplet with optical anisotropy (optical anisotropy) uniformly dispersed in a polymer network. The Polymer Stabilized Liquid Crystal (PSLC) is also a liquid crystal with optical anisotropy uniformly dispersed in a relatively low concentration polymer, and a common polymer stabilized liquid crystal adopts a cholesteric liquid crystal, and can have bistable characteristics of two states, namely a bright state and a dark state, under an environment without applied voltage.
In one embodiment of the present application, the polymer liquid crystal layer 25 includes a Polymer Dispersed Liquid Crystal (PDLC), and the working principle thereof is as follows: by applying an electric field (e.g., an electric field applied by an integrated circuit), the refractive index matching relationship between the liquid crystal and the polymer in the polymer liquid crystal layer 25 can be adjusted, and the light emitted from the backlight module 30 can be modulated in a scattering or transmission manner. Specifically, the method comprises the following steps: the optical axis orientation of the polymer dispersed liquid crystal microdroplets can be adjusted by applying an electric field, and when the refractive indexes of the two are matched, a transparent state is presented. The electric field is removed and the liquid crystal droplets restore the original state of astigmatism, thereby performing the display. When the light adjusting film 20 is powered off, the polymer dispersed liquid crystal molecules are randomly arranged, so that light cannot penetrate through the film, and the effect is seen as a milky opaque state. When the light adjusting film 20 is powered on, the polymer dispersed liquid crystal molecules in the middle of the film are orderly arranged under the action of an electric field, so that light can penetrate through the film, and the effect is a transparent colorless film.
Further, as shown in fig. 1 and 3, the light adjusting film 20 includes: a first electrode 23 and a second electrode 24 located in each dimming area a; the first electrodes 23 and the second electrodes 24 are arranged at intervals, the number of the first electrodes 23 is equal to that of the second electrodes 24, and further, the first electrodes 23 and the second electrodes 24 in different dimming areas a are arranged independently; the first electrode 23 and the second electrode 24 are used to drive the polymer liquid crystal layer 25 to control the light transmittance of each dimming region a.
It should be understood that, as for the second electrode 24, which may be a common electrode, the second electrodes 24 in all the dimming areas a may be connected into an integral structure; namely: the first electrode 23 is an independent electrode, the second electrode 24 is a common electrode, and each light adjusting area A is independently controlled by adjusting the first electrode 23;
similarly, the first electrodes 23 may be used as a common electrode, and the first electrodes 23 in all the dimming regions a may be connected to form an integral structure; namely: the second electrode 24 is an independent electrode, the first electrode 23 is a common electrode, and the light modulation regions a are independently controlled by adjusting the second electrode 24.
In some embodiments of the present application, the first electrode 23 and the second electrode 24 are located on two sides of the polymer liquid crystal layer 25, the first electrode 23 is disposed on a side close to the first substrate 21, the second electrode 24 is disposed on a side close to the second substrate 22, as shown in fig. 1, the first electrode 23 and the second electrode 24 are both bulk electrodes, that is: the first electrode 23 and the second electrode 24 are independently provided in each light modulation area a.
If the second electrode 24 is a common electrode and is connected as an integral structure, the second electrode 24 is an integral planar structure; if the first electrodes 23 are common electrodes and are connected to form an integral structure, the first electrodes 23 are in an integral planar structure.
It is understood that, in the above three ways, the first electrode 23 and the second electrode 24 both form an electric field in the vertical direction to control the polymer liquid crystal layer 25.
In another embodiment of the present application, in addition to the above-mentioned arrangement of the electrodes, the first electrode 23 and the second electrode 24 may be arranged on the same side of the polymer liquid crystal layer 25; the first electrodes 23 and the second electrodes 24 are sequentially arranged at intervals, and in each light modulation region a, the first electrodes 23 and the second electrodes 24 are strip-shaped electrodes.
In another embodiment of the present application, in addition to the above-mentioned arrangement of the electrodes, the first electrode 23 and the second electrode 24 may be arranged on the same side of the polymer liquid crystal layer 25; the first electrode 23 and the second electrode 24 are located in different layers, the first electrode 23 is close to the polymer liquid crystal layer 25 relative to the second electrode 24, and in each light modulation area a, the first electrode 23 is a strip-shaped electrode and the second electrode is an integral planar electrode.
It is understood that the polymer liquid crystal layer 25 can be controlled by forming a horizontal electric field by the first electrode 23 and the second electrode 24 in the above two ways.
The electrode is set in any of the above manners, and can be adjusted according to actual manufacture and requirements.
In order to reduce the unnecessary influence of the first electrode 23 and the second electrode 24 on the light transmittance of the light modulating film 20 as much as possible, it is preferable to use transparent electrodes for the first electrode 23 and the second electrode 24. For example: the first electrode 23 and the second electrode 24 may be made of a transparent electrode material such as Indium Tin Oxide (ITO), Indium Gallium Zinc Oxide (IGZO), Indium Zinc Oxide (IZO), or the like.

In some embodiments of the present application, the electrode line 50 is made of Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO), wherein the Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO) is a transparent conductive material, so as to avoid the problem of the light transmittance of the light adjusting film 20 being decreased due to the routing of the electrode line 50.
It will be appreciated that indium zinc oxide conducts electricity better than indium tin oxide and is less resistive, and therefore: when the transmission impedance of the electrode wire 50 is too large, the electrode wire 50 made of the indium tin oxide material transmits when the transmission impedance of the electrode wire 50 can meet the transmission requirement by using the indium tin oxide, and the electrode wire 50 made of the indium tin oxide material transmits according to the actual requirement, so that the cost can be reduced while the transmission requirement is met.
It should be understood that the electrode wire 50 may also be other Transparent Conductive Oxide (TCO) materials besides indium zinc oxide and indium tin oxide.
In some embodiments of the present application, the first electrode 23 and the second electrode 24 are each provided with an electrode pattern, the electrode patterns may be in various shapes, and the electrode patterns of the respective electrodes may be identical in pattern and different in size. For example, the shape of the electrode patterns may be rectangular or circular, and in one embodiment of the present application, in order to simplify the manufacturing work and increase the manufacturing efficiency, as shown in fig. 3, the electrode patterns of each first electrode 23 and each second electrode 24 are both rectangular, and the sizes of the electrode patterns are the same.
In some embodiments of the present application, as shown in fig. 1, the backlight assembly 30 includes: the light guide plate 32 includes a light emitting surface, a bottom surface and a side surface, the light emitting surface is located at a side close to the light adjusting film 20, the bottom surface is opposite to the light emitting surface, and the light source 31 is disposed at the side surface.
