Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a wearable display device. Background Technology

[0002] With the advancement of electronic products and the rapid development of technology, today's flexible wearable display devices are becoming increasingly integrated, smaller in size, and more practical. Breakthroughs in flexible electronics technology have made it possible to manufacture flexible displays with superior performance, simple structure, light weight, low cost, and mass production capabilities.

[0003] In portable electronic devices such as smartphones, smartwatches, and fitness trackers, the displays consume a significant portion of the power and require continuous image display, resulting in high power consumption and frequent charging, which is inconvenient for consumers. Therefore, low power consumption is crucial, but current wearable displays fail to meet these requirements. Summary of the Invention

[0004] In view of this, this application provides a wearable display device to address the technical problem of excessive power consumption of existing wearable display devices.

[0005] In a first aspect, this application provides a backlight module, including:

[0006] Substrate, wherein the substrate is a flexible substrate;

[0007] A light-emitting layer includes light-emitting units and connecting units. The light-emitting unit array is disposed on the substrate, and the connecting units are used to connect the light-emitting units and fix the light-emitting units to the substrate.

[0008] The material of the light-emitting unit includes a long afterglow photoluminescent material, and the material of the connecting unit includes a flexible fiber material.

[0009] In some embodiments, the material of the connecting unit includes at least one of cellulose, polyester, and polyamide;

[0010] And / or, the substrate is made of at least one of polydimethylsiloxane and polyimide.

[0011] In some embodiments, the front view of the light-emitting unit is at least one of a circle, rectangle, ellipse, triangle, and rhombus; and / or

[0012] The front view of the connecting unit is at least one of a straight line, a curve, or a broken line.

[0013] The backlight module provided in this application is assembled using long-afterglow photoluminescent materials and flexible fiber materials. It achieves the purpose of emitting light by exciting the long-afterglow photoluminescent materials with natural light, thus realizing the effect of zero power consumption backlighting. Moreover, it does not require charging, fundamentally solving the high power consumption problem of backlight modules in the prior art.

[0014] Secondly, this application provides a wearable display device, including the backlight module, display module and encapsulation layer described above, wherein the encapsulation layer covers the backlight module and forms an encapsulation space, and the display module is mounted on the side of the encapsulation layer near the light-emitting layer and located outside the encapsulation space.

[0015] In some embodiments, the backlight module has multiple light-emitting areas, the display module is movably mounted on the encapsulation layer, and the position of the display module corresponds to any one of the light-emitting areas.

[0016] In some embodiments, the encapsulation layer is further provided with a one-way light-transmitting layer on the side away from the substrate. The one-way light-transmitting layer is located outside the encapsulation space and is used to transmit light from the outside towards the light-emitting layer and to block the light-emitting layer from emitting light towards the outside.

[0017] When the display module is combined with the unidirectional light-transmitting layer, the light emitted by the light-emitting layer located under the display module is emitted through the display module.

[0018] In some embodiments, a brightness enhancement film layer is provided on the side of the light-emitting layer away from the substrate, and the brightness enhancement film layer is located within the encapsulation space.

[0019] In some embodiments, the display module includes a photodetector for detecting the brightness of the light emitted by the light-emitting layer;

[0020] When the detected brightness is below the threshold, the photodetector issues a warning signal to indicate that the energy of the emitting layer in the current emitting area is insufficient; or

[0021] When the brightness is detected to be below the threshold, the photodetector sends a command to move the display module to another light-emitting area.

[0022] In some embodiments, when the brightness is detected to be below a threshold, the display module moves to another light-emitting area, and the light-emitting layer with insufficient energy receives external ambient light to recharge it. This cycle is repeated to achieve zero power consumption.

[0023] In some embodiments, the wearable display device further includes a transmission component, which includes a driving element and a positioning element. The driving element and the positioning element are both disposed on the encapsulation layer and located outside the encapsulation space. The driving element is used to drive the display module to move from one of the light-emitting areas to another, and the positioning element is used to fix the display module and make the position of the display module correspond to the light-emitting area.

[0024] The wearable display device provided in this application is assembled using long afterglow photoluminescent materials and flexible fiber materials. On the one hand, it effectively improves the stretchability of the wearable display device, and on the other hand, it enables the wearable display device to achieve zero power consumption and no need for charging. The afterglow photoluminescent material absorbs external light (ambient light or sunlight) through the encapsulation layer to store energy, and then the light is emitted through the display module to display the picture and text.

[0048] Firstly, such as Figure 1 As shown, this application provides a backlight module 10, including a substrate 11 and a light-emitting layer 12;

[0049] The light-emitting layer 12 includes light-emitting units 121 and connecting units 122. The light-emitting units 121 are arrayed on the substrate 11, and the connecting units 122 connect each light-emitting unit 121 and fix each light-emitting unit 121 to the substrate 11.

[0050] The material of the light-emitting unit 121 includes a long afterglow photoluminescent material, the substrate 11 is a flexible substrate, and the material of the connecting unit 122 includes a flexible fiber material.

[0051] The backlight module 10 provided in this application uses an environmentally friendly energy-storing self-luminous material—a long-afterglow photoluminescent material. This material absorbs light energy under visible light irradiation and emits the absorbed energy in a low-frequency visible form under dark conditions. This light-emitting principle is called photoluminescence (i.e., the luminescence phenomenon caused by visible light excitation). Thus, the backlight module 10 of this application can absorb natural light to store energy and then emit light without needing to be charged, achieving zero power consumption for the backlight and fundamentally solving the high power consumption problem of the backlight module 10 in the prior art.

[0052] In some embodiments, the light-emitting unit 121 comprises a rare-earth light-emitting material matrix and an activator;

[0053] The rare earth luminescent material matrix includes at least one of Y2O2S, SrAl2O4, CaAl2O4, CaS, Y2O3, CaTiO3, and Sr2MgSi2O7;

[0054] The activator is Dy3+ 、Nd 3+ La 3+ 、Tb 3+ Ti 4+ Eu 2+ Tm 3+ Eu 3+ Mg 2+ Si 4+ Pr 3+ At least one of them.

[0055] It should be noted that Y represents yttrium, O represents oxygen, S represents sulfur, Sr represents strontium, Al represents aluminum, Ca represents calcium, Ti represents titanium, Mg represents magnesium, Si represents silicon, Dy represents dysprosium, Nd represents neodymium, La represents lanthanum, Tb represents terbium, Eu represents europium, Tm represents thulium, and Pr represents praseodymium.

[0056] In applications, long-afterglow photoluminescent materials generally use different rare-earth luminescent material matrices and different activators. Different combinations result in different emission spectrum characteristics, leading to variations in emission color, intensity, and afterglow time. The emission color is typically determined by both the emission color of the rare-earth luminescent material matrix and the emission color of the activator. When the matrix and activator emit light together, color superposition occurs, resulting in several types of long-afterglow photoluminescent materials, including those emitting green, blue, red, and white light.

[0057] Specifically, the long-afterglow photoluminescent material involved in this design is an aluminate system (the rare earth luminescent material matrix is ​​SrAl2O4 and / or CaAl2O4). Its advantages are that it does not contain radioactive substances, is environmentally friendly, has an ultra-long afterglow, high brightness, an afterglow time of more than 1500 minutes, and a service life of more than 10 years.

[0058] In some embodiments, the material of the connecting unit 122 includes a flexible fiber material, and the material of the connecting unit 122 includes at least one of cellulose, polyester, and polyamide.

[0059] Using flexible fiber materials to make the connecting unit 122 can effectively improve the overall stretchability of the backlight module 10, making it suitable for use in flexible wearable display devices. Specifically, the materials include cellulose, polyester, and polyamide, all of which have good flexibility and stretchability.

[0060] In some embodiments, the substrate 11 is a flexible material, and the material of the substrate 11 includes at least one of polydimethylsiloxane and polyimide.

[0061] Using a flexible material as the substrate 11 allows the backlight module 10 to be used in flexible wearable devices, enriching its application scenarios. Specifically, polydimethylsiloxane and polyimide are used as the substrate 11. PDMS and PI have advantages such as simple processing, good elasticity, and good thermal stability.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the front view of the light-emitting unit 121 is at least one of a circle, rectangle, ellipse, triangle, and rhombus.

[0063] In applications, the light-emitting unit 121 can be designed with different shapes, such as square and circular shapes as shown in the figure. The number of materials distributed on the same substrate 11 is the same, but the circular shape has a larger area than the square shape, which can improve the brightness. That is, using different shapes can improve brightness and save costs.

[0064] In some embodiments, such as Figure 1 and Figure 2 As shown, the front view of the connecting unit 122 is at least one of a straight line, a curve, and a broken line.

[0065] In the application, the fabrication process of the light-emitting layer 12 is mainly based on the principle of imprinting a stretchable flexible fiber material with a corrugated or buckle-like shape onto the substrate 11. This corrugated or buckle-like shape helps to release stress during stretching, resulting in a larger strain range. When the pre-strain is released, the connecting unit 122 forms a wave-shaped structure. On the one hand, the light-emitting layer 12 with this structure can adapt to external deformation by changing the wavelength and amplitude of the wave; on the other hand, this wave-shaped design can effectively improve the stretchability of the backlight module 10.

[0066] Secondly, this application provides a wearable display device, such as... Figure 3 As shown, it includes the backlight module 10, the display module 20, and the encapsulation layer 30 mentioned above;

[0067] The encapsulation layer 30 covers the backlight module 10, and the encapsulation layer 30 forms a sealed encapsulation space 300.

[0068] The display module 20 is mounted on the side of the encapsulation layer 30 near the light-emitting layer 12, and the display module 20 is located outside the encapsulation space 300.

[0069] This application provides a wearable display device in which a light-emitting layer 12 provides the light source for a display module 20. The light-emitting layer 12 is composed of a long-afterglow photoluminescent material and a flexible fiber material. The long-afterglow photoluminescent material absorbs ambient sunlight through an encapsulation layer 30 to store energy, and then the light is emitted through the display module 20 to provide backlight, thereby achieving the purpose of zero-power backlight. No charging is required during use, which greatly improves the user's convenience.

[0070] Furthermore, the encapsulation layer 30 is a structure such as transparent glass or a transparent film layer, which facilitates the light-emitting unit 121 within the encapsulation space 300 to absorb external natural light for energy storage.

[0071] In some embodiments, such as Figure 3 and Figure 4 As shown, the backlight module 10 has multiple light-emitting areas, and the display module 20 is movably mounted on the encapsulation layer 30, with the position of the display module 20 corresponding to any one of the light-emitting areas.

[0072] It should be noted that the light-emitting area includes part of the substrate 11 and the light-emitting layer 12, that is, the entire backlight module 10 is divided into multiple light-emitting areas. The position of the display module 20 corresponds to any one of the light-emitting areas. By movably mounting the display module 20 on the encapsulation layer 30, when the energy in the light-emitting area corresponding to the display module 20 is insufficient (the brightness of the emitted light decreases, and after dropping to the threshold), the display module 20 can be moved to another light-emitting area, so that the display module 20 can display the image and / or text in a timely manner, ensuring that the wearable display device can always maintain normal display function.

[0073] In applications, movable installation methods include sliding installation and rolling installation. Specifically, a guide rail can be set on the encapsulation layer 30, and a slider can be set on the display module 20. Through the sliding cooperation between the slider and the guide rail, the display module 20 can be moved on the backlight module 10.

[0074] In some embodiments, such as Figure 3 As shown, a one-way light-transmitting layer 40 is also provided on the side of the encapsulation layer 30 away from the substrate 11. The one-way light-transmitting layer 40 is located outside the encapsulation space 300. The one-way light-transmitting layer 40 is used to transmit light from the outside to the light-emitting layer 12 and to block the light-emitting layer 12 from emitting light to the outside.

[0075] When the display module 20 is combined with the one-way light-transmitting layer 40, the light emitted by the light-emitting layer 12 located under the display module 20 passes through the display module 20.

[0076] By setting a one-way light-transmitting layer 40, light from the external environment (ambient light or sunlight) can pass through the one-way light-transmitting layer 40 and the encapsulation layer 30 and be directed to the light-emitting unit 121 in the encapsulation space 300, where it is absorbed and stored as energy. When the display module 20 is combined with the one-way light-transmitting layer 40, the light-emitting unit 121 located in the light-emitting area under the display module 20 can emit light through the display module 20 to display images and / or text.

[0077] In some embodiments, such as Figure 3 As shown, a brightness enhancement film layer 50 is provided on the side of the light-emitting layer 12 away from the substrate 11, and the brightness enhancement film layer 50 is located within the encapsulation space 300.

[0078] The brightness of the backlight can be improved by using the brightness enhancement film layer 50, the main material of which is a prism light-concentrating anti-reflection film.

[0079] In some embodiments, the display module 20 includes a photodetector for detecting the brightness of the light emitted by the light-emitting layer 12;

[0080] When the brightness is detected to be below the threshold, the photodetector sends a warning signal to indicate that the energy of the light-emitting layer 12 in the current light-emitting area is insufficient.

[0081] It should be noted that this is because the afterglow brightness of the long-afterglow photoluminescent material shows signs of gradual decline. Therefore, the brightness of the long-afterglow photoluminescent material is detected by a photodetector. When the brightness of the long-afterglow material decreases, the corresponding light-emitting area of ​​the display module 20 is switched, so that the light-emitting area after energy storage can continue to display in conjunction with the display module 20, thereby achieving the purpose of cycle.

[0082] In application, the photodetector detects the brightness of the light-emitting unit 121 in the current light-emitting area and reminds the user that the light-emitting unit 121 in the current light-emitting area is low on energy by issuing a warning signal such as a prompt sound or a warning light. The user can move the display module 20 according to the warning signal and manually move the display module 20 to another light-emitting area that has been fully charged, thereby ensuring the display function.

[0083] It should be noted that the brightness value of the light emitted through the light-emitting area can pass through the display module 20. The brightness of the screen and / or text that can be displayed normally in the display area of ​​the display module 20 is the threshold. When the emitted brightness is lower than the threshold, the screen and / or text displayed by the display module 20 will become darker or unclear.

[0084] In another embodiment, the display module 20 includes a photodetector for detecting the brightness of the light emitted by the light-emitting layer 12; when the detected brightness is below a threshold, the photodetector issues a command to move the display module 20 to another light-emitting area.

[0085] This also enables automatic switching of the position of the display module 20, ensuring that the light-emitting area corresponding to the display module 20 can emit sufficient brightness to ensure the normal display of the display module 20.

[0086] In some embodiments, when the brightness is detected to be below a threshold, the display module 20 moves to another light-emitting area, and the light-emitting layer 12 with insufficient energy receives ambient light to recharge. This cycle repeats to achieve zero power consumption. In application, since the display module 20 is provided with a one-way light-transmitting layer 40, the light-emitting layer 12 can only emit light through the display module 20. Similarly, when the display module 20 is located in a light-emitting area, the light-emitting layer 12 in that area is blocked and cannot receive ambient light until the energy of the light-emitting unit 121 is exhausted. When the photosensor detects that the brightness is below the threshold, it will issue a reminder or automatically switch positions, moving the display module 20 to another light-emitting area with full energy. The light-emitting unit 121 in the original light-emitting area with insufficient energy can then receive ambient light to recharge. This cycle repeats until zero power consumption and no recharging is required.

[0087] In some embodiments, such as Figure 5 As shown, the wearable display device also includes a transmission component 60, which moves the display module 20 from the current light-emitting area to another light-emitting area according to the command issued by the photodetector.

[0088] In some embodiments, the transmission assembly 60 includes a drive member 61 and a positioning member (not shown in the figure). Both the drive member 61 and the positioning member are disposed on the encapsulation layer 30 and located outside the encapsulation space 300. The drive member 61 is used to drive the display module 20 to move from one light-emitting area to another light-emitting area, and the positioning member is used to fix the display module 20 and make the position of the display module 20 correspond to the light-emitting area.

[0089] This not only enables the movement of the display module 20, but also ensures that the display module 20 corresponds to the position of the light-emitting area, thus ensuring that the display module 20 can display the image normally.

[0090] Specifically, such as Figure 5 and Figure 6 As shown, the driving component 61 includes a mechanical gear 611 and a roller 612. The roller 612 is disposed on the encapsulation layer 30 and arranged along the length direction of the backlight module 10. The display module 20 is connected to the roller 612, and the mechanical gear 611 is connected to the roller 612. The mechanical gear 611 is used to drive the display module 20 to move on the roller 612. The positioning component includes a latch, which is disposed on the display module 20. When the display module 20 reaches the designated position, the latch locks the position of the display module 20 to fix it in place and prevent it from moving, which would cause the display image to become blurry.

[0091] Furthermore, each light-emitting area is equipped with a corresponding clip to fix the display module 20.

[0092] In applications, such as Figure 5 and Figure 6 As shown, connected to the buckle is a brightness signal transducer 70, which has a brightness signal recognition function. Its working principle is to convert light energy into electrical energy. The brightness signal transducer 70 can recognize the brightness transmission signal of the light-emitting unit 121. The recognized signal can move the buckle. After the buckle is moved, the display module 20 slides under the action of the mechanical gear 611 and the roller 612 to the next buckle, and so on.

[0093] In applications, such as Figure 7 As shown in the figure, the illustration is a schematic diagram of the use of wearable display devices. The wearable display devices mentioned above include, but are not limited to, smartwatches, smart bracelets, etc.

[0094] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0095] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
