Referring to fig. 1A and 1B, the display 100 may include a plurality of display units DU1, DU2, DU3, DU4 and at least one photochromic structure PCS for being combined into a display device DD. In this embodiment, the display 100 may be a tiled display device formed by combining a plurality of display units DU1 to DU 4. It should be noted that the display device DD of the present embodiment is composed of 4 display units DU 1-DU 4 (as shown in fig. 1B), but the invention is not limited thereto. In other embodiments, the display device DD may be combined by other numbers of display units. On the other hand, the display units DU1 to DU4 of the present embodiment are illustrated by taking a rectangle as an example, but the present invention is not limited thereto. In other embodiments, the display unit may also be circular, hexagonal, octagonal, or other suitable shape.
Each of the display units DU 1-DU 4 may include a first substrate S1 and a second substrate S2 disposed opposite to each other, and sealant SL1 disposed between the first substrate S1 and the second substrate S2. In some embodiments, a backlight plate, a light emitting diode (e.g., an organic light emitting diode or an inorganic light emitting diode), or a combination thereof may be used as the light emitting sources of the display units DU1 to DU 4. The display units DU 1-DU 4 may be liquid crystal display units, light emitting diode display units or other suitable display units. In bookIn the embodiment, the light intensities of two adjacent display units DU 1-DU 4 are I respectively1And I2(As shown in FIG. 1A, the light intensities of the light beams L1 and L2 emitted from two adjacent display units DU1 and DU2 are I respectively1And I2). In the embodiment, the first substrate S1 may be an active array substrate, and the second substrate S2 may be a color filter substrate, but the invention is not limited thereto.
In the present embodiment, the sealant SL1 may be disposed at the boundary of each of the display units DU1 to DU4, for example, the sealant SL1 may be disposed around each of the display units DU1 to DU 4. The sealant SL1 may be an ultraviolet light curing sealant, an infrared light curing sealant, a thermosetting sealant, or a combination thereof, and the sealant may be acrylic, epoxy resin or acryl epoxy resin, but not limited thereto. In some embodiments, the display units DU 1-DU 4 may include a display medium layer (not shown) disposed in a space defined by the first substrate S1, the second substrate S2, and the sealant SL 1. The display medium layer may be a liquid crystal layer, for example, the medium layer may include liquid crystal molecules that can be rotated or switched by a horizontal electric field (in-plane-switching) or liquid crystal molecules that can be rotated or switched by a vertical electric field (vertical-switching), but is not limited thereto, and may also be other suitable display media such as organic light emitting diodes, inorganic light emitting diodes, and the like.
Referring to fig. 1A and fig. 1C, the photochromic structure PCS may be disposed between the peripheral frame sealant SL1 and the second substrate in each of the display units DU 1-DU 4, and thus, the photochromic structure PCS is disposed around each of the display units DU 1-DU 4, in other words, at the boundary BD between any two adjacent display units DU1 and DU2 in the tiled display device DD, and the light transmittance T% of the photochromic structure PCS and the light intensity I of the two adjacent display units DU1 and DU21、I2Is proportional to the average value of (c). That is, when I of two adjacent display units DU1 and DU21、I2When the average value of the light transmittance is higher, the light transmittance T% of the light-induced discoloration structure PCS is higher, and the light is more transparent; when I of two adjacent display units DU1, DU21、I2The lower the average value of (A), the lower the photochromic structure PCThe lower the light transmittance T% of S, the more opaque. The light transmittance T% of the photochromic PCS structure can be measured by the absorbed light intensity (I)1And I2Average value of) to reduce the brightness difference between the splicing region (e.g. the boundary between two adjacent display units DU1, DU 2) and the display region, so as to avoid the occurrence of an obvious splicing seam between two adjacent display units DU1, DU2, thereby improving the problem of overall picture discontinuity, and improving the viewing quality of the user.
On the other hand, since the light transmittance of the photochromic PCS decreases as the intensity of the absorbed light becomes weaker, even in a state where the display 100 does not display a picture (or a state where the brightness is low), no obvious joint line appears between any two adjacent display units DU1 to DU4, and the viewer is unlikely to see the internal components of the display 100 from the joint area. That is, the display 100 has good quality of the whole screen regardless of whether the display is in a state of displaying the screen or in a state of not displaying the screen. For example, the light intensity (I) absorbed by the photochromic structure PCS1And I2Average value of) is large, the photochromic structure PCS is in a transparent state; and the light intensity (I) absorbed by the photochromic structure PCS1And I2Average of (d) the photochromic structure PCS assumes a dark state.
In some embodiments, the photochromic structure PCS may include an ionic dye compound, for example, a compound represented by the following chemical formula 1. The ionic dye compound has color when not irradiated with light (or has weak light intensity), and free radicals which can initiate polymerization or crosslinking after visible light is absorbed by irradiated light, so that the photochromic structure PCS is in a transparent state or a white state.
[ chemical formula 1]
In chemical formula 1, R1 to R4 may be the same as or different from each other, and each may be independently selected from any one of the group consisting of alkyl (alkyl), aryl (aryl), aralkyl (arylalkyl), alkaryl (alkaryl), alkenyl (alkinyl), alkynyl (alkinyl), alicyclic (alicyclic), heterocyclic (heterocyclic), and allyl (allyl).
In chemical formula 1, D may be selected from any one of the group consisting of methine (methine), polymethine (polymethine), triarylmethane (triarylmethane), indoline (indoline), thiazine (thiazine), xanthene (xanthene), oxazine (oxazine), azine (azine), cyanine (cyanine), carbocyanine (carbocyanine), hemicyanine dye (hemicyanine), rhodamine (rhodamine), and azamethine (azamethine).
In chemical formula 1, B may be selected from any one of the group consisting of xanthene (xanthene) and oxonol (oxonol).
Further, as shown in FIG. 1B, the photochromic structure PCS may be disposed around each of the display units DU 1-DU 4. That is, the vertical projection of the photochromic structure PCS on the first substrate S1 may be substantially similar to the vertical projection of the sealant SL1 on the first substrate S1, but the invention is not limited thereto. Fig. 2 is a schematic top view of a display according to another embodiment of the invention. As shown in fig. 2, the display 100 may optionally include a light-shielding material SM disposed around the display device DD, such that the photochromic structure PCS may be selectively disposed only between any two adjacent display units DU 1-DU 4. The light shielding material SM may be an opaque material such as a material suitable for a black matrix (black matrix).
Please refer to fig. 3. Fig. 3 is a partial cross-sectional view of a display according to another embodiment of the invention. As shown in fig. 3, in some embodiments, the photochromic structure PCS may be a plurality of photochromic structures separated from each other and disposed around each display unit, and when the light intensities of two adjacent display units are different, the light transmittance T% of the photochromic structure PCS may be changed by the absorbed light intensity, so that the light transmittance of the photochromic structure PCS is gradually changed as being away from the boundary between two adjacent display units DU 1-DU 4. In this way, the light transmittance of each photochromic structure PCS can pass through the absorbed light intensity (I)1And I2Average value of) is adjustedThe brightness difference between the splicing region (e.g. the boundary between two adjacent display units DU 1-DU 4) and the display region can be further reduced, so that the continuity of the whole picture is better, and the viewing quality of the user is further improved.
Please refer to fig. 4A to 4C. Fig. 4A to 4C are schematic top views of displays according to still another embodiment of the invention. The photochromic structures PCS may be disposed separately, besides the partial or surrounding display units, in some embodiments, the arrangement of the separated photochromic structures PCS may be in a matrix arrangement (as shown in fig. 4A), but the invention is not limited thereto. In other embodiments, the arrangement of the plurality of photochromic structures PCS separated from each other may be disposed in a staggered manner (as shown in fig. 4B and 4C). In addition, the present invention does not limit the shape or number of the photochromic structures PCS. For example, the photochromic structure PCS may be rectangular (as shown in fig. 4A and 4B) or hexagonal (as shown in fig. 4C).
Referring to fig. 1A, fig. 1C and fig. 5, fig. 5 is a schematic cross-sectional view of a display according to still another embodiment of the invention. The photochromic structure PCS may be disposed in the display units DU 1-DU 4 (in-cell), for example, the photochromic structure PCS is disposed between the sealant SL1 and the second substrate S2 in each of the display units DU 1-DU 4, but the invention is not limited thereto. In other embodiments, the photochromic structure PCS may be disposed on the display units DU 1-DU 4 (on-cell), for example, the photochromic structure PCS may be disposed at the boundary of the display units DU 1-DU 4 (as shown in FIG. 5).
Fig. 6 is a schematic cross-sectional view of a display according to still another embodiment of the present invention, wherein the display 200 is substantially the same as the display 100, except that the sealant SL2 of the display 200 is used as a photochromic structure, so the same or similar elements have the same or similar reference numerals, and the connection relationship, materials and processes of the other components are described in detail in the foregoing, and thus are not repeated herein.
In some embodiments, as shown in fig. 6, the sealant SL2 of the display 200 can be used as a photochromic structure, that is, it adopts or contains the same photochromic as the photochromic structure PCSColor material for light penetration rate and I of sealant SL21And I2Is proportional to the average value of (c). In this way, when the thickness of the sealant SL2 is greater than that of the photochromic structure PCS shown in fig. 1A, the brightness difference between the splicing region (e.g., the boundary between any two adjacent display units DU 1-DU 4) and the display region can be further reduced, so that the continuity of the whole screen is better.
In some embodiments, the display 200 may optionally include a reflective layer RL disposed between the sealant SL2 and the first substrate S1. Therefore, under the condition that the light can be reflected to the light-emitting surface through the reflecting layer RL, the brightness difference between the splicing area and the display area can be further reduced, so that the continuity of the whole picture is better. In some embodiments, the material of the reflective layer RL may include a material capable of reflecting visible light, such as aluminum (Al), silver (Ag), chromium (Cr), copper (Cu), nickel (Ni), titanium (Ti), molybdenum (Mo), magnesium (Mg), platinum (Pt), gold (Au), or a combination thereof.
In summary, in the display of the above embodiments, the photochromic structure is disposed at the boundary between two adjacent display units, and the light transmittance and I of the photochromic structure1And I2Is proportional to the average value of (a), the light transmittance of the photochromic structure can be determined by the intensity of the absorbed light (I)1And I2Average value of) to reduce the brightness difference between the splicing region (e.g., the junction between two adjacent display units) and the display region, and avoid the occurrence of an obvious splicing seam between two adjacent display units, so as to improve the problem of overall picture discontinuity, and improve the viewing quality of users.
