Meanwhile, the orthographic projection of the second electrode 14 of the first liquid crystal cell on the first substrate 11 covers the second spacing region 26, and the orthographic projection of the fourth electrode 24 of the second liquid crystal cell on the first substrate 11 covers the first spacing region 16, i.e. the second electrode 14 and the fourth electrode 24 are spatially staggered. And the orientation direction of the first liquid crystal box is the same as that of the second liquid crystal box, so that the polarization directions of all light incident to the liquid crystal unit can be unified through the first liquid crystal box and the second liquid crystal box, and the light leakage phenomenon is avoided.
In order to ensure that the dimming module is in a bright state and a dark state, in this embodiment, a polarizer is further disposed on one side of the liquid crystal cell, and an absorption axis of the polarizer is the same as an orientation direction of the first liquid crystal cell, that is, the bright state or the dark state of the dimming module can be realized by matching the polarizer with the liquid crystal cell.
In a specific example, the first liquid crystal cell and the second liquid crystal cell are in a normally white mode, the first liquid crystal cell is located at a front end of the second liquid crystal cell in terms of an incident direction of light, the polarizer is located at a rear end of the second liquid crystal cell, and an absorption axis of the polarizer is 0 degree.
When no voltage is applied, as shown in fig. 1, the liquid crystal molecules of the first liquid crystal cell are vertically arranged relative to the first substrate, the liquid crystal molecules of the second liquid crystal cell are vertically arranged relative to the first substrate, and external incident light firstly enters the first liquid crystal cell, enters the second liquid crystal cell through the first liquid crystal cell, and enters the polarizer through the second liquid crystal cell; the polaroid absorbs light parallel to the absorption axis of the polaroid, and the dimming module is in a bright state by transmitting the light vertical to the absorption axis of the polaroid.
When a voltage is applied, as shown in fig. 2, external incident light enters the first liquid crystal cell, in the first liquid crystal cell, liquid crystal molecules covered by an electric field formed by the first electrode and each second electrode are arranged in parallel with respect to the first substrate, and the rest of the liquid crystal molecules are arranged vertically with respect to the first substrate, and enter the second liquid crystal cell through the first liquid crystal cell. That is, all incident lights are unified into polarized lights parallel to the first substrate through the second electrodes and the fourth electrodes which are arranged in a staggered manner, so that the problem of light leakage is effectively solved. When the polarized light parallel to the first substrate enters the polarizer with the absorption axis of 0 degree, the polarized light is absorbed by the polarizer, external incident light cannot penetrate through the dimming module, and the dimming module is in a dark state.
Similarly, in another specific example, the first liquid crystal cell and the second liquid crystal cell are in a normally white mode, the first liquid crystal cell is located at a front end of the second liquid crystal cell in terms of an incident direction of light, the polarizer is located at a front end of the first liquid crystal cell, and an absorption axis of the polarizer is 0 degree.
When no voltage is applied, the dimming module exhibits a bright state, similar to the previous example.
When a voltage is applied, external incident light first enters the polarizer, and the polarizer absorbs light parallel to the absorption axis of the polarizer and transmits light perpendicular to the absorption axis of the polarizer, that is, perpendicular light of the external incident light enters the first liquid crystal cell.
In the first liquid crystal box, liquid crystal molecules of the first liquid crystal covered by an electric field formed by the first electrode and each second electrode are arranged in parallel relative to the first substrate, the rest of the liquid crystal molecules are arranged vertically relative to the first substrate, the liquid crystal molecules parallel to the first substrate absorb incident vertical light, and the liquid crystal molecules vertical to the first substrate transmit the incident vertical light and enter the second liquid crystal box.
In the second liquid crystal cell, liquid crystal molecules of the second liquid crystal covered by the electric field formed by the third electrode and each fourth electrode are arranged in parallel relative to the first substrate, and the rest of the liquid crystal molecules are arranged vertically relative to the first substrate.
Therefore, when voltage is loaded, the external incident light is absorbed by the polarizer, the first liquid crystal box and the second liquid crystal box respectively, the external incident light cannot penetrate through the dimming module, namely, the external incident light passes through the first liquid crystal box and the second liquid crystal box which are the same in orientation direction, and the second electrodes of the first liquid crystal box and the fourth electrodes of the second liquid crystal box are arranged in a staggered mode, so that the problem of light leakage is effectively solved, and meanwhile, the dimming module can be in a bright state and a dark state by matching with the polarizer.
It should be noted that, the present application does not limit the absorption axis angle of the polarizer, and does not limit the orientation directions of the first liquid crystal cell and the second liquid crystal cell, and a person skilled in the art should set the absorption axis angle of the polarizer and the orientation directions of the first liquid crystal cell and the second liquid crystal cell according to the actual application requirement, so as to satisfy that the absorption axis direction of the polarizer is the same as the orientation directions of the first liquid crystal cell and the second liquid crystal cell, which is not described herein again.
In this embodiment, the first liquid crystal cell and the second liquid crystal cell which are stacked, are arranged in a staggered manner by strip electrodes and are controlled in a partitioned manner, and the polarizer of which the absorption axis direction is the same as the orientation direction of the first liquid crystal cell and the orientation direction of the second liquid crystal cell realize the partitioned dimming control of the dimming module.
It should be noted that, the present application does not specifically limit the specific structures of the first electrode and the second electrode of the first liquid crystal cell, and the third electrode and the fourth electrode of the second liquid crystal cell, and in an alternative embodiment, the first electrode is close to the light incident side of the light modulation module relative to the second electrode, or the first electrode is far away from the light incident side of the light modulation module relative to the second electrode; the third electrode is close to the light incident side of the dimming module relative to the fourth electrode, or the third electrode is far away from the light incident side of the dimming module relative to the fourth electrode.
In this embodiment, in terms of the incident direction of light, the first electrode may be an upper electrode of the first liquid crystal cell, and may also be a lower electrode of the first liquid crystal cell; the third electrode may be an upper electrode of the second liquid crystal cell, or may be a lower electrode of the second liquid crystal cell; the zone dimming of the dimming module can be realized.
In order to further enhance the dark state display of the dimming module, in an alternative embodiment, at least one of the first liquid crystal and the second liquid crystal is a dye liquid crystal.
In the present embodiment, a dye liquid crystal is used as the liquid crystal molecules of the first liquid crystal cell and the second liquid crystal cell, that is, the liquid crystal molecules are doped with a dichroic dye, and the dye liquid crystal can better absorb incident light and take on a dark state. Specifically, a guest-host dye liquid crystal in which dichroic dyes are dissolved in a liquid crystal constitutes a liquid crystal in which liquid crystal molecules are host and dichroic dye molecules are guest. The dichroic dye has a characteristic of selectively absorbing light, and thus, the arrangement of dichroic dye molecules may be induced by liquid crystal molecules, thereby controlling absorption and transmission of light. In this embodiment, the dye liquid crystal is a negative liquid crystal molecule, when no voltage is applied, each liquid crystal molecule is perpendicular to the first substrate and the second substrate, and the dye liquid crystal does not absorb external incident light; when voltage is loaded and an electric field is formed, the dye liquid crystals under the action of the electric field deflect along the orientation direction, the dye molecules in the dye liquid crystal molecules rotate along with the liquid crystal molecules and are parallel to the first transparent substrate and the second transparent substrate, and external incident light is absorbed by the dye molecules to present a dark state.
It should be noted that, the dye liquid crystal molecules are not specifically limited in the present application, and may be positive liquid crystal or negative liquid crystal, and meanwhile, the display modes of the first liquid crystal cell and the second liquid crystal cell of the dimming module are not specifically limited in the present application, and may be a normally white mode or a normally black mode.
In an alternative embodiment, the polarizer is located on a side of the liquid crystal cell away from the light incident side.
In this embodiment, consider that the direct exposure of polaroid is when externally incidenting, the easy problem that appears the polaroid ageing and the material characteristic descends when strong ultraviolet irradiation especially, will the polaroid sets up the inboard of module of adjusting luminance can avoid directly receiving external incident light, is favorable to stabilizing the performance of module of adjusting luminance increases the life of module of adjusting luminance.
