[0036] In related technologies, to assist in display or enhance visual effects, a lighting module with a highly integrated design with the electronic paper display panel and driving circuit is generally used. Although the lamp module with an integrated design with the electronic paper display can meet basic lighting needs, it is difficult to replace, upgrade or maintain independently during production or subsequent use, which increases the complexity of production and supply chain management and cannot meet the increasingly changing market demands.

[0037] To address the aforementioned issues, this application provides a lighting module for electronic paper displays, which enables modular and separate installation of the light source component and the electronic paper display. This achieves physical decoupling and independent assembly of the lighting module and the electronic paper display, effectively solving the problems of difficulty in replacing, upgrading, and maintaining traditional integrated lighting modules.

[0038] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0039] Figure 1 This is a schematic diagram of the structure of the display device shown in the embodiments of this application; Figure 2 This is another structural schematic diagram of the display device shown in the embodiments of this application.

[0040] See Figure 1 and Figure 2 The lighting module for electronic paper displays of this application includes a frame 110 and a light source assembly 120.

[0041] The frame 110 includes at least two independent frame units 111, which are connected end-to-end by a detachable connector 112. The frame units 111, as independent components of the frame 110, can be made of metal profiles or injection molded engineering plastics. The connector 112 is mainly used for the mechanical structure of detachably fixing adjacent frame units 111. The connector 112 can be at least one of a snap-fit, bolt, pin, or connecting plate, thereby facilitating disassembly and maintenance between adjacent frame units 111. The frame 110 of this application achieves a modular assembly through a separate design using the frame units 111 and the connector 112.

[0042] Each frame unit 111 has an inner wall with an isolation edge 1111, and the frame 110 forms an upper mounting area 113 and a lower mounting area 114 through the isolation edges 1111. The isolation edge 1111 refers to a protruding edge structure on the inner wall of the frame unit 111. The isolation edge 1111 can be an integrally formed protruding edge structure with the frame unit 111, which divides the mounting area and enhances the overall structural strength of the frame 110. The upper mounting area 113 refers to the top space enclosed by the isolation edge 1111. Adjusting the height of the isolation edge 1111 on the frame unit 111 allows adjustment of the mounting position of the lamp source assembly 120 on the lamp tube module. The lower mounting area 114 refers to the accommodating space formed below the isolation edge 1111. Adjusting the overall size of the frame 110 allows for the matching of different electronic paper display shapes.

[0043] The light source assembly 120 is installed in the upper mounting area 113, and the lower mounting area 114 is used to install the electronic paper display. The light source assembly 120 is a light-emitting unit primarily used to provide illumination. Installing the light source assembly 120 in the upper mounting area 113 enables directional illumination of the electronic paper display installed in the lower mounting area 114. The light source assembly 120 can be an LED light strip.

[0044] The lamp module of this application has a frame 110 assembled from multiple independent frame units 111 via connectors 112 to form a complete frame structure. The isolation edges 1111 on the inner wall of each frame unit 111 form a continuous boundary after assembly, dividing the interior of the frame 110 into upper and lower mounting areas. The lamp source assembly 120 is mounted in the upper mounting area 113, physically isolated from the electronic paper display in the lower mounting area 114 by the isolation edges 1111. When maintenance of the lamp source assembly 120 is required, the corresponding frame unit 111 and connector 112 can be disassembled to replace the components in that area individually, without disassembling the entire lamp module. Through this modular structure, the lamp module of this application can also flexibly adjust its frame size according to the usage scenario, such as by increasing or decreasing the number of frame units 111 to adapt to different display sizes.

[0045] In some embodiments, the lighting module may further include a lampshade 130. The lampshade 130 may be disposed in the upper mounting area 113. The lampshade 130 may be made of polycarbonate or acrylic material. The lampshade 130 can prevent external dust and liquids from contacting the light source assembly. It should be understood that the lampshade 130 is a light-transmitting protective structure, wherein the lampshade 130 may be a transparent, colorless ruler or a colored material, and the lighting color can be changed by utilizing the material color of the lampshade 130. The lampshade 130 and the inner wall of at least one frame unit 111 form a mounting cavity (not shown in the figure), and the light source assembly 120 is disposed in the mounting cavity for installation. The mounting cavity refers to the enclosed space enclosed by the lampshade 130 and the inner wall of the frame unit 111, wherein the lampshade 130 can be installed on the frame unit 111 by a snap-fit ​​or sliding rail structure to form a mounting cavity for installing the light source assembly. The internal space of the cavity and the lower mounting area 114 are physically separated by the isolation edge 1111. The lamp source component 120 is installed in the mounting cavity, which can avoid interference between the electronic paper display and the lamp source component 120.

[0046] When the light source needs to be replaced, only the lamp cover 130 needs to be removed to directly contact the mounting cavity, thereby replacing the light source component 120 in the corresponding mounting cavity without damaging the overall frame structure.

[0047] In some embodiments, the mounting cavity may be disposed around the upper mounting region 113. Distributing the mounting cavity around the upper mounting region 113 means that the mounting cavity is arranged in a surrounding manner along the circumferential edge of the upper mounting region 113. This surrounding design structure provides a continuously distributed accommodating space for the lamp source assembly 120, allowing the light source assembly 120 to uniformly cover the edge of the electronic paper display when operating within the mounting cavity. The lamp source assembly 120 can be fixedly mounted within the mounting cavity using either snap-fit ​​or adhesive methods.

[0048] Traditional lighting modules typically employ single-sided or partial lighting, resulting in concentrated light source distribution and significant attenuation of illuminance in edge areas. This solution achieves uniform circumferential lighting through a ring-shaped mounting cavity, effectively eliminating dark areas at the edges. Furthermore, the detachable connection between the cavity and the frame allows the light source assembly 120 to form an independent module, facilitating individual maintenance or upgrades.

[0049] It is understood that in the lighting module of this application, the distribution position of the light source component 120 can correspond to the electronic paper display on which the lighting module is applied. When the electronic paper display is polygonal, the light source component 120 can emit light from at least one side of the electronic paper display. When the electronic paper display is circular, the light source component 120 can emit light from at least a portion of the side of the electronic paper display.

[0050] In some embodiments, the lighting module may further include a light guide plate (not shown in the figure). The light guide plate is disposed in the upper mounting area 113 and is a plate-shaped optical structure with light conduction and diffusion functions. The light guide plate can be injection molded from acrylic or polycarbonate material and have microstructures etched onto its surface, thereby converting point or line light sources into a uniform surface light field. A gap space (not shown in the figure) can be formed between any side of the light guide plate and any frame unit 111, and the lamp source assembly 120 is installed and fixed within this gap space. The gap space can be achieved by providing limiting protrusions or snap-fit ​​structures on the inner wall of the frame unit 111. These limiting protrusions or snap-fit ​​structures control the position and size of the gap space, thereby controlling the installation position of the lamp source assembly and ensuring that the incident angle of the light from the lamp source assembly 120 matches the light guiding direction of the light guide plate according to a preset relationship, thus meeting the lighting requirements.

[0051] It is understandable that when the lamp source assembly 120 is powered on, the light emitted enters from the side of the light guide plate. Through the total internal reflection effect and the scattering effect of the surface microstructure inside the light guide plate, the linear light is converted into a uniform surface light source, thereby providing illumination for the electronic paper display located in the lower mounting area 114. In addition, the light guide plate also provides protection for the electronic paper display, preventing damage to the display caused by impacts from external objects.

[0052] Traditional electronic paper lighting modules typically use a light source to directly illuminate the display area, which results in an overly bright central area and insufficient edge illumination. This application addresses this by using a side-light-introducing design on a light guide plate, which allows light to be released gradually and evenly during transmission, effectively eliminating the phenomenon of bright and dark stripes.

[0053] This application provides two completely different lighting effects by combining the light source component and the lampshade in the lighting module, as well as combining the light source component and the light guide plate, thereby meeting different production needs.

[0054] In some embodiments, each frame unit 111 is provided with an alignment groove 1112 parallel to the isolation edge 1111. When two adjacent frame units 111 are connected, the connector 112 is inserted into the alignment grooves 1112 of the two adjacent frame units 111 respectively. The alignment groove 1112 can be a linear groove structure opened along the length direction of the frame unit 111, and the size of the alignment groove 1112 matches that of the connector 112. When two adjacent frame units 111 are connected, the connector 112 is simultaneously inserted into the alignment grooves 1112 of the two adjacent frame units 111. Since the alignment groove 1112 is parallel to the isolation edge 1111, when the connector 112 moves along the extension direction of the alignment groove 1112, the inner wall isolation edges 1111 of the adjacent frame units 111 automatically align to the same plane. By using the connector 112 to slide within the alignment groove 1112, the offset between adjacent frame units 111 during installation is effectively prevented. After the connector 112 is fully inserted into the alignment groove 1112, the outer walls of the frame units 111 are flush, ensuring the overall structure is flat. During disassembly, the connector 112 is pulled out in the opposite direction along the groove of the alignment groove 1112, releasing the constraint on the adjacent frame units 111.

[0055] Figure 3 This is a schematic diagram of signal control for a display device shown in an embodiment of this application.

[0056] See also Figure 3 In some embodiments, the lighting module further includes a communication module 140 electrically connected to the light source assembly 120. The communication module 140 includes at least one of a Wi-Fi module, a Bluetooth module, a 4G module, and a 5G module. The communication module 140 is primarily used to establish a wireless data link between the light source assembly 120 and an external control terminal. The electrical connection can refer to signal transmission via a circuit connection, specifically achieved through wire soldering, flexible circuit board wiring, or connector plug-in, and is used to transmit control commands received by the communication module 140 to the light source assembly 120.

[0057] Specifically, the communication module can receive control signals from external terminals via wireless communication protocols. For example, it can receive cloud commands forwarded by a router via a Wi-Fi module, or receive dimming parameters sent by a smartphone via a Bluetooth module. The control signals are then transmitted to the light source component via electrical connection, driving it to adjust brightness, color temperature, or on / off status. Thus, the lighting module can achieve remote control without relying on a physical interface, while also being compatible with multiple communication protocols to meet the needs of different scenarios.

[0058] In some embodiments, the lighting module further includes an environmental sensing module 150 electrically connected to the light source assembly 120. The environmental sensing module 150 includes at least one of a light sensor and an infrared sensor. The environmental sensing module 150 is primarily used to detect external environmental parameters; specifically, it can employ at least one of a light sensor with an integrated light intensity detection unit or an infrared sensor that detects thermal radiation from a human body or object.

[0059] When the environmental sensing module 150 includes a light sensor, it adjusts the brightness of the light source by collecting ambient light intensity data in real time. When the environmental sensing module 150 includes an infrared sensor, it triggers the switching of the light source's operating mode by sensing human activity.

[0060] It is understood that the environmental sensing module 150 forms a closed-loop control circuit with the light source assembly 120 through electrical connection.

[0061] As an example, the environmental sensing module 150 may include both a light sensor and an infrared sensor. When the lighting module of this application is in operation, if the light sensor detects that the ambient light intensity is higher than a set threshold, it reduces the brightness of the lamp source component 120 to reduce energy consumption; if the detected ambient light intensity is lower than the threshold, it increases the brightness of the lamp source component 120 to ensure display quality; when the infrared sensor detects a human body approaching, it activates the lamp source component 120 to enter a high-brightness mode, and automatically switches to a low-power standby state when no human activity is detected within a set time. Through the coordinated operation of the two types of sensors included in the environmental sensing module 150, the lighting module of this application can dynamically adjust its lighting strategy based on composite environmental parameters.

[0062] In this embodiment, the lighting module for electronic paper displays of this application adopts a frame structure composed of detachable frame units and an upper and lower mounting area formed by the isolation edge set by the inner wall of the frame unit. This enables modular and separate installation of the light source component and the electronic paper display, allowing the lighting module to flexibly combine the frame units according to the size or shape requirements of the electronic paper display during the production process. This adapts to the ever-changing customized production needs and the user's personalized adjustment of the lighting effects, achieving the effect of physical decoupling and independent assembly of the lighting module and the electronic paper display. This effectively solves the problem of traditional integrated lighting modules being difficult to replace, upgrade, and maintain.

[0063] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a display device and corresponding embodiments.

[0064] See Figures 1 to 3The display device of this application includes an electronic paper display body 200 and a lighting module 100 as described above. The electronic paper display body 200 is disposed within the lower mounting area 114 of the lighting module 100.

[0065] The electronic paper display body 200 can be a display unit based on electrophoretic display technology. The electronic paper display body 200 can use a flexible or rigid substrate combined with a driving circuit to achieve image information display function. The lighting module 100 is a light source system independent of the electronic paper display body 200. The lighting module 100 provides auxiliary lighting for the electronic paper display body 200 when the display device is operating.

[0066] The lower mounting area refers to the space inside the light module frame used to fix the main body of the electronic paper display. Specifically, it can be achieved by forming a limiting structure through the isolation edge of the frame unit to ensure the optical matching accuracy between the main body of the electronic paper display and the light source component.

[0067] The display device of this application sets the electronic paper display body 200 and the light module 100 as independent modules. The frame 110 of the light module 100 is divided into upper and lower mounting areas by the isolation edge 1111 on the frame unit 111. The light source assembly 120 is installed in the upper mounting area 113, and the structural dimensions of the lower mounting area 114 match the edge of the electronic paper display body 200 to form a limiting fixation. The electronic paper display body 200 is fixed within the lower mounting area 114. When it is necessary to replace or upgrade the light module, only the light module needs to be disassembled independently.

[0068] In some embodiments, the electronic paper display body 200 is provided with a display area 210, and an isolation gap is provided between the edge of the display area 210 and the edge of the isolation edge 1111. The display area 210 refers to the range on the electronic paper display body 200 where the electronic ink layer forms an effective image output. The isolation gap can refer to the non-contact distance between the edge of the display area 210 and the isolation edge 1111 of the border unit 111.

[0069] Specifically, when the electronic paper display body 200 is installed in the lower mounting area 114 of the light module 100, the boundary of the display area 210 is limited to the inside of the isolation gap. This isolation gap can be used to form an air insulation layer when the heat generated by the light source assembly 120 is conducted through the frame unit 111, thereby reducing the heat conduction efficiency and reducing the interference of heat on the electronic paper display body 200.

[0070] In some embodiments, the display device further includes a spacer 300 surrounding the edge of the electronic paper display body 200. The electronic paper display body 200 abuts against the light module 100 via the spacer 300.

[0071] The isolation pad 300 can be made of at least one of silicone, rubber, EVA foam pad, or foam material to achieve elasticity and low thermal conductivity. A physical isolation layer is formed at the contact interface.

[0072] The isolation pad 300 is continuously distributed along the circumferential edge of the electronic paper display body 200. The isolation pad 300 can be distributed by integral molding or segment splicing. By covering all edge contact areas of the electronic paper display body 200, local stress concentration is avoided.

[0073] It is understood that the display device in this application utilizes the isolation pad 300 to absorb mechanical impacts generated during assembly or use through elastic deformation, thereby dispersing the pressure distribution on the contact surface. This can effectively prevent structural damage to the electronic paper display body 200 caused by hard contact. At the same time, the isolation pad can effectively block the heat generated by the light module 100 during operation from being transferred to the electronic paper display body 200, thereby avoiding the impact of the heat generated by the light module during operation on the performance of the electronic ink material, and effectively ensuring the display effect and operational stability of the display device.

[0074] The display device of this application may also include a lighting control module 400 between the lighting module and the main body of the electronic paper display. The lighting control module 400 is used to receive lighting control signals sent by the main body of the electronic paper display 200, or remote control signals received by the communication module 140, or lighting control signals generated by the environmental sensing module 150 based on the detected environmental conditions. The lighting control module 400 converts the received control signals into response control signals for the light source component 120, thereby realizing the control of parameters such as the light color, light effect, and light brightness of the light source component 120.

[0075] The light source component in this application can achieve various special effects lighting such as gradient colors, flashing, flowing water, breathing, seven colors, rising step by step, and marquee.

[0076] In this embodiment, the display device of this application, by adopting a frame structure composed of detachable frame units and forming upper and lower mounting areas by the isolation edges set by the inner walls of the frame units, realizes the modular and separate installation of the light source component and the electronic paper display. This allows the light module to flexibly combine the frame units according to the size or shape requirements of the electronic paper display during the production process, thereby adapting to the ever-changing customized production needs and the user's personalized adjustment of the lighting effects. This achieves the effect of physical decoupling and independent assembly of the light module and the electronic paper display, effectively solving the problem of traditional integrated light modules being difficult to replace, upgrade, and maintain.
