Description

Technical Field

[0001] The utility model relates to a display structure, in particular to a display structure with a decorative function. Background Art

[0002] Generally, if a display product has a decorative requirement, such as a display product that needs to match the wood grain interior of a car, the method is mostly to attach a wood grain decorative panel to the display so that the display and the car interior appear to be integrated.

[0003] When a wood grain decorative plate is attached to a display, a translucent scattering ink layer and a silver reflective layer are usually printed under the wood grain decorative plate. When the display is turned off, the silver ink will reflect external light to present the wood grain pattern; when the display is turned on, the content of the display can be presented through the translucent scattering ink layer. However, in this design, whether the display is turned on or off, the scattering effect of the translucent scattering ink will always exist, causing the pictures or text displayed on the display to become blurred, which seriously affects the user's viewing experience. Utility Model Content

[0004] The utility model aims to provide a display structure, which can solve the problem in the prior art that the display function of the display is affected by scattering caused by a semi-transparent scattering ink layer.

[0005] In order to achieve the above-mentioned object, the utility model provides a display structure. The display structure includes a display layer, a reflective polarizing layer, a dispersed liquid crystal layer and a pattern layer. The reflective polarizing layer is arranged on one side of the display layer. The dispersed liquid crystal layer is arranged on the side of the reflective polarizing layer opposite to the display layer. The pattern layer is arranged on the side of the dispersed liquid crystal layer opposite to the reflective polarizing layer.

[0006] In an embodiment of the present invention, the pattern layer comprises a screen printing layer or an inkjet coating layer.

[0007] In an embodiment of the present invention, the pattern layer includes a plurality of pattern units arranged at intervals.

[0008] In an embodiment of the present invention, each of the pattern units has an inclination angle relative to the boundary of the dispersed liquid crystal layer, and the inclination angle is between 0 degrees and 90 degrees.

[0009] In an embodiment of the present invention, the transmittance of the pattern layer is between 50% and 100%.

[0010] In an embodiment of the present invention, the display structure further comprises a complementary pattern layer, and the complementary pattern layer is disposed between the reflective polarizing layer and the display layer.

[0011] In an embodiment of the present invention, the pattern of the complementary pattern layer corresponds to the pattern of the pattern layer, and the color of the complementary pattern layer is complementary to the color of the pattern layer.

[0012] In an embodiment of the present invention, the reflective polarizing layer includes a reflective brightness enhancement film, a metal grating polarizer or a cholesterol liquid crystal layer.

[0013] In one embodiment of the present invention, the dispersed liquid crystal layer is configured to receive an external voltage, wherein the dispersed liquid crystal layer is in a scattering state when no power is supplied, and is in a transparent state when power is supplied.

[0014] In one embodiment of the present invention, when the dispersed liquid crystal layer is in a scattering state, a plurality of liquid crystal molecules in the dispersed liquid crystal layer are irregularly arranged.

[0015] As described above, the display structure provided by the present invention mainly increases the light utilization rate and light penetration rate of the display layer when the display layer is turned on by combining the design of the reflective polarizing layer with the dispersed liquid crystal layer, thereby preventing the pattern layer from affecting the display effect of the entire display layer. On the other hand, by combining the design of the reflective polarizing layer with the dispersed liquid crystal layer, the external light can be reflected and the light can be homogenized when the display layer is turned off, thereby achieving a visual effect of highlighting the pattern layer.

[0037] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following will specifically cite the preferred embodiments of the present invention and provide a detailed description in conjunction with the attached drawings. Furthermore, the directional terms mentioned in the present invention, such as up, down, top, bottom, front, back, left, right, inside, outside, side, surrounding, center, horizontal, lateral, vertical, longitudinal, axial, radial, topmost or bottommost, etc., are only referenced to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0038] Please also refer to Figure 1 and Figure 2 The display structure 1 of this embodiment mainly includes a display layer 10, a reflective polarizing layer 20, a dispersed liquid crystal layer 30, a pattern layer 40 and a cover plate 50 which are arranged in sequence. That is to say, the reflective polarizing layer 20 and the dispersed liquid crystal layer 30 are located between the display layer 10 and the pattern layer 40, and can provide reflection and scattering functions respectively, so that the display layer 10 can highlight the pattern of the pattern layer 40 when it is closed, and the display layer 10 will not be affected by the pattern layer 40 when it is turned on and can play its good display effect. The cover plate 50 is arranged in front of the pattern layer 40 to protect the components of each layer located behind the cover plate 50.

[0039] Specifically, the display layer 10 is mainly used to provide a display function. The reflective polarizing layer 20 is disposed on one side of the display layer 10. In addition to being used to increase the light utilization rate of the display layer 10 when the display layer 10 is turned on, the reflective polarizing layer 20 can also be used to reflect external light when the display layer 10 is turned off to increase the visibility of the pattern layer 40. In one embodiment, the reflective polarizing layer includes a dual brightness enhancement film (DBEF), a metal grating polarizer, or a cholesterol liquid crystal layer.

[0040] The dispersed liquid crystal layer 30 is disposed on the side of the reflective polarizing layer 20 opposite to the display layer 10. The dispersed liquid crystal layer 30 may be a polymer dispersed liquid crystal layer (PDLC), and the dispersed liquid crystal layer 30 mainly controls the arrangement order of liquid crystal molecules 31 therein through voltage to switch from a scattering state to a transparent state. Specifically, the dispersed liquid crystal layer 30 is connected to an external voltage P1, such as Figure 1 As shown, when the external voltage P1 is turned off, the dispersed liquid crystal layer 30 is not energized, and the liquid crystal molecules 31 are arranged irregularly, so that the dispersed liquid crystal layer 30 looks foggy, so that when light passes through the dispersed liquid crystal layer 30, it can be scattered. Figure 2 As shown, when the external voltage P1 is turned on and the dispersed liquid crystal layer 30 is energized, the liquid crystal molecules 31 are arranged in an orderly manner, so that the dispersed liquid crystal layer 30 appears to be in a transparent state.

[0041] The pattern layer 40 is disposed on the side of the dispersed liquid crystal layer 30 opposite to the reflective polarizing layer 20. In one embodiment, the pattern layer 40 includes a screen printing layer or an inkjet coating. In addition, the pattern layer 40 is a semi-transparent layer and has a certain transmittance. In one embodiment, as Figure 3 and Figure 4As shown, the pattern layer 40 includes a plurality of pattern units 41 arranged at intervals. That is, there is a spacing G1 between any two adjacent pattern units 41, and the spacing G1 can be adjusted according to different optical requirements, so that the pattern units 41 can be arranged at equal intervals or at unequal intervals. In one embodiment, the spacing G1 between two adjacent pattern units 41, the width or transparency of the pattern unit 41 itself can jointly determine the transmittance of the entire pattern layer 40. In this embodiment, the transmittance of the pattern layer 40 is between 50% and 100%. In addition, in one embodiment, the pattern unit 41 can be a twill pattern unit, and the pattern unit 41 has an inclination angle θ relative to the boundary of the dispersed liquid crystal layer 30, and the inclination angle θ is between 0 degrees and 90 degrees, preferably 45 degrees, but not limited thereto. The inclination angle θ can be adjusted according to the display requirements of the display layer 10 to avoid the pattern unit 41 and the display layer 10 from generating interference fringes (Moire). In a specific example, the pattern layer 40 can be a wood grain pattern layer or a pattern layer of other patterns.

[0042] Please refer again Figure 1 , when the display layer 10 and the dispersed liquid crystal layer 30 are both closed, the dispersed liquid crystal layer 30 is in a scattered state. Therefore, external light (such as light L1) can pass through the pattern layer 40 and the dispersed liquid crystal layer 30 in sequence through the cover plate 50, and be reflected by the reflective polarizing layer 20. At this time, the light reflected by the reflective polarizing layer 20 can return to the dispersed liquid crystal layer 30 again, and be scattered by the dispersed liquid crystal layer 30 (such as light L1) and emitted from the pattern layer 40, so that the display layer 10 can highlight the visual effect of the pattern layer 40 when it is in the closed state. Specifically, by closing the dispersed liquid crystal layer 30, the light L1 reflected by the reflective polarizing layer 20 is scattered, so an optical effect similar to anti-glare can be produced, thereby increasing the visibility of the pattern layer 40.

[0043] Please refer again Figure 2 When the display layer 10 and the dispersed liquid crystal layer 30 are both turned on, the dispersed liquid crystal layer 30 is transparent. The light generated by the display layer 10 can directly pass through the reflective polarizing layer 20, the dispersed liquid crystal layer 30, the pattern layer 40 and the cover plate 50 in sequence, so that the content displayed by the display layer 10 can be clearly identified by the user.

[0044] The display structure of the present invention can also have different structural designs. Figure 5 and Figure 6 , Figure 5 and Figure 6 The following are schematic diagrams of a display structure in a closed state and an open state according to another embodiment of the present invention. Figure 1 and Figure 2The display structures 1 shown are substantially the same, the only difference being that Figure 5 and Figure 6 The display structure 2 further includes a complementary pattern layer 40'. The complementary pattern layer 40' is disposed between the reflective polarizing layer 20 and the display layer 10. In the present embodiment, the color of the complementary pattern layer 40' is complementary to the color of the pattern layer 40. For example, the colors of the two may be red and green or yellow and purple with complementary properties, but are not limited to single colors. The pattern layer 40 may be a pattern layer formed by a combination of different colors or a combination of the same color system. In this case, the complementary pattern layer 40' is a complementary pattern layer formed by a corresponding complementary color combination or a complementary combination of the same color system. In one embodiment, the complementary pattern layer 40' is mainly a pattern obtained by image processing the pattern layer 40 using computer software, so the complementary pattern layer 40' can match the pattern layer 40, and a grayscale effect is presented after the two are superimposed. In one embodiment, the complementary pattern layer 40' may also include a screen printing layer or an inkjet coating, and is a translucent pattern with a certain transmittance.

[0045] Therefore, if Figure 5 As shown, when the display layer 10 and the dispersed liquid crystal layer 30 are both closed, the dispersed liquid crystal layer 30 is in a scattered state. Therefore, external light (such as light L4) can pass through the pattern layer 40 and the dispersed liquid crystal layer 30 in sequence through the cover plate 50, and be reflected by the reflective polarizing layer 20. At this time, the light reflected by the reflective polarizing layer 20 can return to the dispersed liquid crystal layer 30 again, and is scattered by the dispersed liquid crystal layer 30 (such as light L5) and then emitted from the pattern layer 40. At this time, the proportion of external light penetrating the display layer 10 and reflected is very small, so the influence of the complementary pattern layer 40' can be ignored, so when the display layer 10 is in the closed state, it can only highlight the original visual effect of the pattern layer 40.

[0046] Another example Figure 6 As shown, when the display layer 10 and the dispersed liquid crystal layer 30 are both turned on, the dispersed liquid crystal layer 30 is in a transparent state. The light generated by the display layer 10 can directly pass through the complementary pattern layer 40', the reflective polarizing layer 20, the dispersed liquid crystal layer 30, the pattern layer 40 and the cover plate 50 in sequence. At this time, the grayscale effect is generated due to the superposition of the complementary pattern layer 40' and the pattern layer 40, and this grayscale effect only affects the display brightness of the display layer 10, and does not affect the visual effect displayed by the display layer 10.

[0047] As described above, the display structure provided by the present invention mainly increases the light utilization rate and light penetration rate of the display layer when the display layer is turned on by combining the design of the reflective polarizing layer with the dispersed liquid crystal layer, thereby preventing the pattern layer from affecting the display effect of the entire display layer. On the other hand, by combining the design of the reflective polarizing layer with the dispersed liquid crystal layer, the external light can be reflected and the light can be homogenized when the display layer is turned off, thereby achieving a visual effect of highlighting the pattern layer.
