[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. The features and exemplary embodiments of various aspects of the present application will be described in detail below.

[0050] Figure 1 Schematic diagram of the cross-sectional structure of a display module in the prior art. Figure 1 As shown, in the prior art, a decorative film layer structure 40 is added on the basis of the structure of the screen body 10, the polarization optical element 20 and the cover plate structure 30 stacked in sequence to achieve the effect of environmental integrated display. However, due to the low transmittance of the polarization optical element 20, according to research, the transmittance of the polarization optical element 20 can only reach 42%-45%, so it has a greater impact on the amount of outgoing light from the screen body 10 reaching the human eye. In addition, the transmittance of the cover plate structure 30 is about 92%-93%, and the transmittance of the decorative film layer structure 40 is also about 50%. In summary, the overall transmittance of the environmental integrated display module of such a structure can only reach about 20%, which affects the display effect of the display module. Therefore, in order to achieve the set display effect, the power consumption of the display module is usually greatly increased, thereby increasing the operating cost of the display device.

[0051] In view of this, the present application provides a display module and an assembly method thereof, and an intelligent display system, so as to improve the problem of high power consumption of the environment-integrated display module in the prior art.

[0052] Figure 2 The cross-sectional structure diagram of the display module in one embodiment of the present application. The display module only includes a screen body 10 and a decorative film layer structure 40 stacked in sequence. The screen body 10 includes a first display screen body portion D1 located on the display side surface of the screen body 10. The decorative film layer structure 40 is located on the light-emitting side of the first display screen body portion D1. Figure 1 In contrast, in this embodiment, no polarizing optical element is included between the screen body 10 (ie, the first display screen body portion D) and the decorative film layer structure 40 .

[0053] In this embodiment, the polarization optical element 20 with a transmittance of 42%-45% and / or the polarization optical element 20 with a transmittance of 42%-45% are provided. 92～93％ ofThe cover plate 30 is removed, and only the decorative film structure 40 with a transmittance of about 10% to 90% is retained on the display side surface of the screen body 10, so that the transmittance of the display module in this area is significantly improved. Transmittance refers to the proportion of light that can penetrate the layers of the display module and reach the observer's eyes after passing through the display module. When the transmittance increases, it means that when the outgoing light is constant, more light will enter the observer's eyes.

[0054] In one embodiment, preferably, the transmittance of the decorative film structure 40 is about 30% to 85%. For example, it can be 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80% or 85%. More preferably, the transmittance is 45%-75%, which is better.

[0055] In one embodiment, the screen 10 is an organic light emitting diode (OLED) display screen. The display principle of this type of display screen is as follows: under a certain voltage drive, the organic material of the light emitting material layer emits light through the injection and recombination of carriers, and the emitted light enters the human eye after passing through multiple film layers of the screen 10. Therefore, when the transmittance of the display module is significantly improved, the light emitting material layer emits less light to achieve the same display effect as before, that is, the light emitting material layer has a correspondingly lower demand for external electrical energy, thereby reducing the power consumption of the display module in this area and reducing the operating cost of the display device.

[0056] In one embodiment, the screen body 10 is a liquid crystal display screen. In a liquid crystal display screen, the power consumption of the display module is mainly the power consumption of the backlight module and the liquid crystal layer itself. The backlight module is responsible for providing enough light to illuminate the liquid crystal layer so that the image is visible. When the transmittance of the display module is improved, the backlight module only needs to generate less light to ensure that enough light penetrates the multiple film layers of the screen body 10 and illuminates the liquid crystal layer, which makes the backlight module consume less electricity, thereby reducing the power consumption of the entire liquid crystal display module and reducing the operating cost of the display device.

[0057] In one embodiment, optionally, the screen body 10 may also be an organic light emitting diode display screen (Organic Light Emitting Diode, OLED).

[0058] In one embodiment, there is no cover structure between the screen body 10 and the decorative film layer structure 40 , so that the glass structure of the display module is reduced, thereby improving the safety of the display module.

[0059] In one embodiment, at least one side surface of the decorative film layer structure 40 has a decorative texture. For example, the decorative film layer structure 40 has a decorative texture on the display side surface to achieve an environmental integrated display effect. In one embodiment, the decorative texture includes wood grain, leather grain, fabric grain and metal brushed grain.

[0060] In one embodiment, the decorative film layer structure 40 includes a base layer and a decorative texture layer having a decorative texture along the thickness direction of the display module.

[0061] In one embodiment, the decorative texture layer is located on the side of the base layer close to the screen body 10. Optionally, the decorative texture layer is a patterned ink layer. Further optionally, the patterned ink layer is a multi-layered ink layer, and the desired decorative texture, such as wood grain, leather grain, etc., is formed by the multi-layer ink layer.

[0062] In one embodiment, the decorative film layer structure also includes a microstructure layer arranged on the side of the base layer away from the screen body 10 (the first display screen body portion D1), and the microstructure layer may have a patterned structure formed by methods such as embossing and etching; for example, the surface of the microstructure layer is formed with a concave-convex structure to simulate the touch of wood grain, leather grain, fabric grain or metal brushed grain.

[0063] In one embodiment, the decorative texture of the decorative film layer structure 40 is formed by screen ink printing technology. The decorative texture is prepared by screen ink printing technology. The decorative texture can play a decorative and concealing role, so that the display module is integrated with the interior of the venue, and the overall style is more coordinated and consistent, which is more in line with the aesthetic needs of modern users.

[0064] Figure 3 FIG. 1 is a schematic diagram of a cross-sectional structure of a display module in another embodiment of the present application. Figure 3 As shown, the decorative film layer structure 40 includes a base layer 410, a decorative texture layer 420, and a microstructure layer 430 which are sequentially stacked on the display side surface of the screen body 10 (the first display screen body portion D1). The base layer 410 and the microstructure layer 430 can be made of polyethylene terephthalate (PET) material, and the decorative texture layer 420 can be made of ink material, and the decorative texture of the decorative film layer structure is formed by screen ink printing technology. The surface of the microstructure layer 430 is an uneven structure corresponding to the decorative texture, which is used to form the touch of the decorative film layer structure 40.

[0065] In one embodiment, the display side surface of the screen body 10 only includes the first display screen body portion D1. Figure 4 Take this as an example to illustrate. Figure 4 FIG. 1 is a top view of a display module in another embodiment of the present application. Figure 4As shown, the first display screen body D1 of the display area of ​​the display module presents a relatively regular rectangle. It should be understood that Figure 4 The first display screen body D1 of the display module shown is generally an area with lower display effect requirements. Therefore, for this area, removing the polarization optical elements that affect the transmittance of the display module is beneficial to improving the overall transmittance of the display module, thereby reducing the power consumption of the display module in this area, and further reducing the operating cost of the display device.

[0066] In one embodiment, the display module further includes a support structure 50 , and the support structure 50 is located on a surface of the screen body 10 away from the display side.

[0067] Figure 5a This is a top view of a display module in another embodiment of the present application. Figure 5b for Figure 5a The cross-sectional structure diagram of the display module along the AA' direction is shown in FIG. Figure 5a As shown, the display side surface of the screen body 10 only includes the first display screen body D1, and the first display screen body D1 presents a special-shaped structure, and the decorative film layer structure 40 covers the screen body 10 (the first display screen body D1) and the area outside. In addition, there is a non-display area on both sides of the first display screen body D1. Figure 5b As shown, in the thickness direction of the display module, the first display screen body D1 includes a stacked screen body 10 and a decorative film layer structure 40 located on the display side surface of the screen body 10, and a support structure 50 located on the side of the screen body 10 away from the decorative film layer structure 40. Figure 5b As shown, the decorative film structure 40 not only covers the first display screen body D1, but also covers two non-display areas adjacent to the first display screen body D1. This arrangement can better integrate the appearance decoration effects of the display area and the non-display area, and achieve a better environmental integrated display effect.

[0068] In one embodiment, the above-mentioned display module is used in wearable devices such as watches. Such devices generally do not have high requirements for display effects. By replacing the polarization optical element 20 and the cover structure 30 of the display module with a decorative film layer structure 40, the power consumption of the display module can be reduced, thereby effectively extending the battery life of the wearable device.

[0069] Figure 5c for Figure 5a The bottom view of the display module is shown.

[0070] In one embodiment, Figure 5b and Figure 5cAs shown, the support structure 50 of the display module mainly includes a bracket 501 and a cushioning layer 502. The bracket 501 is the main supporting part of the display module, and the cushioning layer 502 is located on the surface of the bracket 501 on the side close to the screen body 10. The bracket 501 and the cushioning layer 502 together provide stable support and protection for the display module, ensuring that the display module can work normally and prolong its service life.

[0071] Figure 6a This is a top view of a display module in another embodiment of the present application. Figure 6b for Figure 6a The cross-sectional structure diagram of the display module along the BB' direction is shown in FIG. Figure 6a As shown, the screen body 10 includes not only the first display screen body D1 but also the second display screen body D2. Figure 5b The display module shown is similar to that shown in FIG. 1 . In the thickness direction of the display module, Figure 6b The display module shown includes a screen body 10 and a decorative film structure 40 stacked in sequence in the first display screen body D1, and includes a screen body 10 and a polarization optical element 20 stacked in sequence in the second display screen body D2.

[0072] This embodiment can meet different display requirements of the screen body at the same time by setting different areas on the surface of the screen body 10, and the different areas respectively include a decorative film layer structure 40 and a polarization optical element 20. Specifically, for the first display screen body D1 with lower display effect requirements, replacing the polarization optical element 20 with a decorative film layer structure 40 can effectively improve the overall transmittance of the display module, thereby reducing the power consumption of the display module in this area, thereby reducing the operating cost of the display device. For the second display screen body D2 with higher display effect requirements, the structure of the polarization optical element 20 in the existing structure is still maintained, which can achieve a higher display contrast and better display effect. Therefore, in this embodiment, by setting the decorative film layer structure 40 and the polarization optical element 20 in different areas, it is possible to take into account the display effect requirements of the same screen body 10 and the requirements of low power consumption operation of the display module while achieving environmental integrated display.

[0073] In one embodiment, the polarizing optical element 20 includes a polarizing plate. Since the polarizing plate has a specific polarization direction, it can control the polarization direction of light and only allow light with the same polarization direction as the polarizing plate to pass through. This helps to reduce reflected light, thereby improving the contrast of the screen 10 and improving the display effect. Therefore, in areas where high display effect requirements are required, it is necessary to retain the polarizing optical element 20.

[0074] In one embodiment, the display module further includes a cover structure 30 , and the cover structure 30 is located on a side of the polarization optical element 20 away from the screen body 10 .

[0075] In one embodiment, the display module further includes an optical adhesive layer 60 , which is located on the first display screen body D1 and between the decorative film structure 40 and the screen body 10 , and is used to attach the decorative film structure 40 to the screen body 10 .

[0076] In one embodiment, Figure 6b As shown, the display module also includes an optical adhesive layer 60, which is located in the second display screen body portion D2, and the optical adhesive layer 60 is located between the polarization optical element 20 and the screen body 10, and between the cover structure 30 and the polarization optical element 20, for completing the attachment between the screen body 10, the polarization optical element 20 and the cover structure 30.

[0077] In one embodiment, the power consumption per unit area of ​​the first display screen body is lower than that of the second display screen body. Optionally, the overall power consumption of the display module can be reduced by optimizing the refresh rates of the first display screen body and the second display screen body. For example, the refresh rates of the screens in various areas can be adjusted according to actual needs and specific application environments of the display module, thereby reducing the overall power consumption of the display module.

[0078] In one embodiment, the screen body 10 includes a plurality of display screen body parts, specifically, a first display screen body part D1 and a second display screen body part D2.

[0079] In one embodiment, the screen body 10 includes two display screen bodies, namely a main screen 11 and a first sub-screen 12 , wherein the first display screen body D1 serves as the first sub-screen 12 , and the second display screen body D2 serves as the main screen 11 .

[0080] In this embodiment, the main screen 11 is used as the main display area, and the first sub-screen 12 is used as the sub-display area, and the display contents of the two are different. For example, the main screen 11 and the first sub-screen 12 are used in display devices such as folding mobile phones. The main screen 11 (that is, the second display screen body D2) can be configured with functions such as high resolution and high refresh rate, such as a refresh rate of 60-120 Hz; the first sub-screen 12 (that is, the first display screen body D1) can be configured with low resolution and low refresh rate functions, such as a refresh rate of 0.0167-0.0083 Hz, refreshed approximately every 1-2 minutes, and running a low power consumption working mode. For example, the first sub-screen 12 can display time, standby patterns, and other scenes where the screen changes are not very many and very fast.

[0081] In one embodiment, the area of ​​the first display screen body D1 is smaller than the area of ​​the second display screen body D2. In some embodiments, for the screen body 10 used in display devices such as foldable mobile phones, the area of ​​the main screen 11 is usually larger than the area of ​​the first sub-screen 12, so as to ensure the user's viewing experience while doing a good job of functional zoning.

[0082] In one embodiment, Figure 6b As shown, the decorative film layer structure 40 and the polarizing optical element 20 are disposed in the same layer. Since the first display screen body D1 only has the decorative film layer structure 40, compared with the second display screen body D2 including the polarizing optical element 20 and the cover plate structure 30, the first display screen body D1 can have a thinner module thickness, which is conducive to the lightweight setting of the first sub-screen 12.

[0083] In one embodiment, Figure 6a As shown, the first display screen body D1 also includes an opening area HA. ​​In the actual application of the display device, the opening area HA can be used to place electronic components such as cameras. The periphery of the opening area HA is completely covered by the decorative film structure 40, which is more conducive to the camera being able to see the hidden electronic components without appearing abrupt.

[0084] In one embodiment, as shown in FIG. Figure 6b , Figure 6c As shown, the first display screen body D1 and the second display screen body D2 are an integrated structure.

[0085] In one embodiment, Figure 6a , Figure 6b , Figure 6c and Figure 6d As shown, the display module includes a transition area BA. Specifically, the transition area BA is located between the first display screen body D1 and the second display screen body D2, and the main screen 11 and the first sub-screen 12 are connected through the transition area BA.

[0086] In one embodiment, Figure 6c As shown, the transition area BA is a bending area, and no decorative film layer structure is arranged on the bending area.

[0087] In one embodiment, the transition area BA is also covered with a decorative film structure 40, specifically as follows: Figure 6a , Figure 6b and Figure 6d Such a setting can increase the area of ​​the decorative texture, making the display module more integrated with the environment.

[0088] In one embodiment, the transition area BA is provided with a transition piece, optionally, such as Figure 6b As shown, for the entire screen body 10, the transition piece is the screen body 10 in this area and the decorative film structure 40 thereon; Figure 6d As shown, for a plurality of independent screen bodies, the transition piece 70 may be a supporting structure in the region and the decorative film structure 40 thereon.

[0089] In one embodiment, the transition piece is made of a flexible material, and the screen body 10 is configured to be able to bend at the transition zone. For example, the display module is set on the surface of the component that needs to be deformed, and can be bent at the transition zone, combined with the decorative film layer structure on the bending area, so that the component is more natural.

[0090] In this embodiment, the bending of the transition zone can be a bending during the preparation process of the product, and its bending state remains unchanged after bending; it can also be bent repeatedly, that is, folded during the use of the product, for example, a folding screen mobile phone.

[0091] Figure 7 FIG. 1 is a top view of a display module in another embodiment of the present application. Figure 7 As shown, the screen body 10 includes a first display screen body D1 and a second display screen body D2, and a transition area BA located between the first display screen body D1 and the second display screen body D2, wherein a decorative film layer structure 40 can be used as the transition area between the first display screen body D1 and the second display screen body D2. Figure 6a compared to, Figure 7 The transition area BA of the display module shown is a special-shaped structure, which can be applied to some special scenarios.

[0092] Figure 8a This is a top view of a display module in another embodiment of the present application. Figure 8b for Figure 8a The cross-sectional structure diagram of the display module along the C-C' direction is shown in FIG. Figure 8a and Figure 8b As shown, the display module includes more than one first display screen body, for example, two first display screen bodies. For better distinction, the two first display screen bodies can be referred to as the first display screen body D1 and the third display screen body D3, respectively. In addition, the display module also includes a second display screen body D2, which is located between the first display screen body D1 and the third display screen body D3. Furthermore, the display module includes three display screen bodies, namely, a main screen 11, a first sub-screen 12, and a second sub-screen 13, wherein the first display screen body D1 serves as the first sub-screen 12, the third display screen body D3 serves as the second sub-screen 13, and the second display screen body D2 serves as the main screen 11.

[0093] Continue to refer Figure 8b As shown, along the thickness direction of the display module, the module structure of the first display screen body D3 is the same as the module structure of the first display screen body D1. Specifically, in the first display screen body D1 and the first display screen body D3, the display module includes a screen body 10 and a decorative film layer structure 40 disposed on the display side surface of the screen body 10.

[0094] It should be noted that the display module mentioned in this embodiment can be applied to related products such as smart home appliances or smart homes, so as to realize the display function of the related products.

[0095] In summary, in this embodiment, the area that needs to display more content and has higher display effect requirements is set as the second display screen body D2, and the second display screen body D2 still uses the polarization optical element 20 and the cover structure 30 to achieve a better display contrast and ensure a better display effect; the area that needs to display less content or has lower display effect requirements is set as the first display screen body D1 and the first display screen body D3, and the polarization optical element 20 and the cover structure 30 with lower transmittance are removed from the first display screen body D1 and the first display screen body D3, and a decorative film layer structure 40 with decorative texture and higher transmittance is used to increase the transmittance of the display module in the first display screen body D1 and the first display screen body D3, thereby reducing the power consumption of the display module in this area, thereby reducing the operating cost of the display device.
