For privacy protection and other reasons, dimming glass is widely applied to structures such as automobile windows, aircraft windows, indoor glass, outdoor glass, projection screens, signboards and the like. According to different control means and principles, the light-adjusting glass can realize the switching between transparent and opaque states of the glass by means of electric control, temperature control, light control, voltage control and other different modes. Such as liquid crystal dimming glass, photochromic glass, etc. The principle of the liquid crystal dimming glass is similar to that of a liquid crystal display screen, when a power supply is turned off, liquid crystals in the glass are irregularly distributed, light rays are scattered, and a fuzzy effect is achieved; when the power is turned on, the liquid crystal is arranged in a direction parallel to the light due to the voltage, so that the light can pass through the glass to form a transparent state. Photochromic glass is composed of a photochromic material and glass, wherein the photochromic material has high sensitivity to specific light (generally ultraviolet light), changes the optical characteristics of the photochromic material when the photochromic material is irradiated by light, and has reversibility, and the material such as AgCl (silver chloride), agBr (silver bromide) and the like is processed into crystals which can form about 15nm in the glass; when the light is blocked and no longer irradiates the material, a reverse reaction occurs and the glass returns to transparent.
The existing dimming glass is mostly liquid crystal dimming glass, the liquid crystal dimming glass achieves the effect of regulating and controlling the light transmittance through the arrangement sequence after the liquid crystal is electrified, when a power supply is turned off, liquid crystals in the liquid crystal dimming glass are irregularly arranged, light rays can be scattered out to show a fuzzy effect, and when the power supply is turned on, the liquid crystals in the liquid crystal dimming glass can be arranged in a direction parallel to the light rays due to voltage, so that the light rays can pass through to form a transparent state. However, due to the limitation of the threshold voltage, the dimming effect of the liquid crystal dimming glass is only two kinds of full-on and full-off, and the adjustment from the full-on state to the full-off intermediate state is difficult to realize.
In addition, in mobile phones, computers, tablet computers and other electronic devices with electronic display screens, due to privacy protection, a peep-proof film is often used, and the peep-proof film uses the optical physical principle of a shutter, and utilizes a grating similar to the shutter to limit light rays within a certain angle, if the horizontal viewing angle exceeds the angle, the visibility is obviously reduced, and the peep-proof effect is achieved, but because the peep-proof film is manufactured into a finished product, the structural parameters of the grating in the peep-proof film are fixed, so that the peep-proof degree of the peep-proof film cannot be adjusted according to actual requirements.
Referring to fig. 1 and 2, fig. 1 shows a schematic diagram of electronic ink, fig. 2 shows a schematic structural diagram of an embodiment of a dimming component according to the present invention, and the dimming component according to the embodiment of the present invention includes a first substrate 100, a second substrate 200, a conductive line 300, and electronic ink 500. The electronic ink 500 includes a plurality of positively charged particles 500a and a plurality of negatively charged particles 500b, the positively charged particles 500a are attracted by negative charges, the negatively charged particles 500b are attracted by positive charges, and the positively charged particles 500a and the negatively charged particles 500b in the electronic ink 500 can be orderly arranged by controlling the releasing positions of the positive charges and the releasing positions of the negative charges. The first substrate 100 and the second substrate 200 are stacked and arranged with the first substrate 100 and the second substrate 200 being spaced apart from each other, i.e., the first substrate 100 and the second substrate 200 form an interlayer space therebetween; the conductive wires 300 are provided with a plurality of conductive wires 300, the plurality of conductive wires 300 are arranged between the first substrate 100 and the second substrate 200, the plurality of conductive wires 300 are arranged in parallel, any two adjacent conductive wires 300 are configured to provide charges with opposite electrical properties, and each conductive wire 300 is configured to be adjustable in input voltage; the electronic ink 500 is filled between the first substrate 100 and the second substrate 200. By arranging a plurality of conductive wires 300 at intervals in an interlayer space formed by the first substrate 100 and the second substrate 200, and filling the electronic ink 500 in the interlayer space, before electrifying, the electronic ink 500 is uniformly dispersed in the interlayer space, so that an opaque effect is formed; after the electric conduction is performed, the conductive wires 300 release charges to the interlayer space between the first substrate 100 and the second substrate 200, the charged particles in the electronic ink 500 are attracted by the charges released by the conductive wires 300 and the conductive wires 300 are close, and as any two adjacent conductive wires 300 are configured to provide charges with opposite electric properties, the positively charged particles 500a and negatively charged particles 500b in the electronic ink 500 are close to different conductive wires 300 respectively, and the space between two adjacent conductive wires 300 is emptied, so that a light transmission effect is formed.
In the above light modulation assembly, a plurality of conductive wires 300 are disposed in a gap between the first substrate 100 and the second substrate 200 which are stacked, each conductive wire 300 is arranged in parallel, any two adjacent conductive wires 300 are configured to provide charges with opposite electrical properties, each conductive wire 300 is configured to have an adjustable input voltage, and the gap between the first substrate 100 and the second substrate 200 is filled with electronic ink 500. When the conductive wires 300 are not electrified, the electronic ink 500 is uniformly dispersed in the gap between the first substrate 100 and the second substrate 200, so that the dimming component is opaque; when the conductive wire 300 is electrified, the positively charged particles 500a in the electronic ink 500 are adsorbed by the conductive wire 300 providing negative charges and gather at the conductive wire 300 providing negative charges, the negatively charged particles 500b in the electronic ink 500 are adsorbed by the conductive wire 300 providing negative charges and gather at the conductive wire 300 providing positive charges, so that the concentration of the electronic ink 500 in a region far from the conductive wire 300 is lower than that of the electronic ink 500 in a region near to the conductive wire 300, the effect of making the light modulation component light-transmitting is achieved, and when the applied voltage is changed, the adsorption degree of the positively charged particles 500a and the negatively charged particles 500b in the electronic ink 500 is also changed, so that the light transmission effect of different degrees is achieved, and the problem that the current light modulation glass is generally only two types of full-on and full-off and the adjustment of the full-off intermediate state is difficult to realize is solved.
When the dimming component is used as a peep-proof film, the conductive wires 300 are arranged to conduct electricity in a partitioned mode, so that the effect of partitioned peep prevention or the effect of regulating and controlling the peep-proof angle is achieved. Specifically, in the interlayer space formed by the first substrate 100 and the second substrate 200, the privacy protection of the partial area can be realized only by electrifying the conductive wires 300 of the partial area, for example, the display screen on the self-service counter of a bank is usually large in size, when strangers exist around the operator, the privacy of the operator is at risk of leakage, and the privacy protection adjustment is performed on the edge area of the display screen, so that the surrounding strangers can be effectively prevented from peeping the privacy of the operator; alternatively, multiple layers of conductive wires 300 are arranged in the thickness direction of the first substrate 100 and the second substrate 200, the arrangement mode of each layer of conductive wires 300 is the same as that in the above embodiment, and the conductive wires 300 of each layer are aligned, after the conductive wires 300 are electrified, the visual angle of the grating structure formed after the electronic ink 500 is attracted by the charges is changed by adjusting the number of layers of the electrified conductive wires 300 (see fig. 3), so that the adjustment of the peep-proof angle can be realized. In addition, by changing one or more parameters of the distance between the first substrate 100 and the second substrate 200, the concentration of the electronic ink 500, and the distribution density of the conductive lines 300, the peep-proof effect of different angles can be formed.
When the dimming component is applied to structures such as automobile windows, aircraft windows, indoor glass, outdoor glass, projection screens and signboards, the degree of light transmission can be adjusted step by step according to actual scene requirements, and the dimming component is not limited to two states of full open or full close. And when the dimming component is applied to the electronic equipment as the peep-proof film, the light transmission degree can be adjusted according to the habit of a user and the requirements of different occasions. For example, the above light modulation assembly is applied to a mobile phone as a peep-proof film, when a user uses the mobile phone in his home, a completely light transmission mode can be selected, and when the user uses the mobile phone in public places, a mode with a higher degree of light impermeability can be selected.
Referring to fig. 4 and 5, fig. 4 is a schematic structural diagram of another embodiment of the dimming component of the present invention, fig. 5 is a front view of the dimming component of fig. 4, in some embodiments, the dimming component further includes a spacer 400, the spacer 400 is disposed between the first substrate 100 and the second substrate 200, and separates a gap between the first substrate 100 and the second substrate 200 into a plurality of mutually isolated blocks, and the electronic ink 500 is dispersed in each block. By arranging the partition 400 to divide the gap between the first substrate 100 and the second substrate 200 into a plurality of blocks, the electronic ink 500 is dispersed in each block, so that when not electrified, the electronic ink 500 is dispersed more uniformly, thereby guaranteeing a uniform light-tight effect, and after electrified, the electronic ink 500 is gathered to different conductive wires 300 in a more uniform manner, thereby avoiding uneven light-tight effect caused by gathering the electronic ink 500 to a certain conductive wire 300.
In some embodiments, the spacers 400 include a plurality of spacers 400, and the plurality of spacers 400 are arranged parallel to each other, so that the electronic ink 500 is further dispersed more uniformly, and a good light-transmitting effect and a good light-non-transmitting effect are ensured.
In some embodiments, the stacking direction of the first substrate 100 and the second substrate 200 is a first direction, the arrangement direction of the plurality of spacers 400 is a second direction, and the size of the spacers 400 in the first direction is greater than the size of the spacers 400 in the second direction. By reducing the size of the spacer 400 in the second direction as much as possible, the projected area of the light modulating element on the first substrate 100 and the second substrate 200 is made smaller, so that the influence of the spacer 400 on the light transmitting effect of the light modulating element is reduced as much as possible.
In some embodiments, the spacer 400 extends from the first substrate 100 to the second substrate 200 in a first direction. By arranging the spacers 400 to extend from the first substrate 100 to the second substrate 200 in the first direction, the concentration of the electronic ink 500 in each block formed by the spacers 400 is kept balanced, and the situation that the concentration of the electronic ink 500 in a part of blocks is too high and the concentration of the electronic ink 500 in a part of blocks is too low due to the transfer of the electronic ink 500 between adjacent blocks, so that the uneven light transmission effect is caused is avoided.
In some embodiments, the spacers 400 are arranged perpendicular to the conductive lines 300. Through arranging the partition 400 and the conductive wires 300 mutually perpendicular, the partition 400 and the conductive wires 300 are combined to form a grid shape, so that the electronic ink 500 presents pixel state distribution after being electrified, and a good light transmission effect is achieved.
In some embodiments, the spacer 400 is OCA (Optically ClearAdhesive) optical cement or polyimide. The OCA optical cement has the characteristics of high clarity, high light transmittance (total light transmittance is more than 99%), high adhesive force, high weather resistance, high water resistance, high temperature resistance, ultraviolet resistance and the like, is easy to control in thickness, can provide uniform spacing, can not cause yellowing, stripping and deterioration after long-time use, and can effectively improve the dimming performance of a dimming component and prolong the service life of the dimming component by using the OCA optical cement as the partition 400. The polyimide spacer 400 can serve as a spacer and also can serve as a buffer for aligning the first substrate 100 and the second substrate 200 at both ends, thereby reducing stress and improving yield.
In the above-described embodiments, the electronic ink 500 includes at least one of a black electronic ink 500 and a color electronic ink 500. The black electronic ink 500 is in an opaque state when completely dispersed, and the degree of light impermeability decreases as the dispersion degree of the black electronic ink 500 decreases, which is easy to change the light transmittance. When the electronic ink 500 includes the color electronic ink 500, the color of the color electronic ink 500 and the location of the block where the color electronic ink 500 is located can be controlled to display the pattern.
In the above embodiment, the conductive line 300 is a transparent conductive line 300. The transparent conductive line 300 has less influence on the light transmission effect, thereby reducing the influence of the conductive line 300 on the light transmission effect. For example, the conductive wire 300 is made of transparent indium tin oxide, and the transparent indium tin oxide has good electrical conductivity and optical transparency, so that the influence on the light transmission effect is reduced on the basis of ensuring the conductive effect, that is, the conductive wire 300 is ensured to release enough charges after being electrified, so that charged particles in the electronic ink 500 are better attracted to gather, and good adjustment of the light transmission effect is achieved.
In some embodiments, the line width of the conductive line 300 is 10 micrometers to 20 micrometers. By controlling the line width of the conductive line 300 to be 10 micrometers to 20 micrometers, the human eye cannot distinguish the conductive line 300 within the line width range, thereby avoiding the conductive line 300 from affecting the light transmission effect. In the above embodiment, the conductive wire 300 is manufactured by the micro flow channel process, and the micro flow channel process is used to operate on the micro size, so as to facilitate the processing of the micro size conductive wire 300.
In some embodiments, the first substrate 100 and/or the second substrate 200 are colorless transparent substrates, and by providing the first substrate 100 and/or the second substrate 200 as colorless transparent substrates, the first substrate 100 and/or the second substrate 200 are prevented from affecting the color of light. For example, when the first substrate 100 and/or the second substrate 200 are glass substrates or PET (polyethylene terephthalate) transparent substrates, the first substrate 100 and/or the second substrate 200 can be used in different situations, such as windows of automobiles, windows of airplanes, indoor glass, outdoor glass, projection screens, signboards, etc., by selecting glass materials suitable for different situations and combining the dimming components formed by the electronic ink 500 with the first substrate 100 and/or the second substrate 200; when the first substrate 100 and/or the second substrate 200 are/is a PET transparent substrate, the peep-proof film made from the foregoing is applied to electronic devices such as a mobile phone, which is beneficial to realizing portability of the electronic devices such as the mobile phone, and is not easy to generate screen breakage.
In some embodiments, the electronic device includes a device main body and a dimming component, where the device main body is provided with a display screen, and the dimming component is attached to one side of the display screen. In the above embodiments, the electronic device includes all the above light adjusting components, so that the electronic device has all the technical effects of the above embodiments, and will not be described herein. The electronic equipment comprises a mobile phone, a computer, a tablet personal computer or other electronic display screens.
