Description

Technical Field

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

[0002] In the field of home appliances, most appliances have control panel displays, and the display methods vary significantly depending on the price range. In related technologies, the button display scheme for the control panel is often chosen based on the product's price, such as surface-printed patterns or internal light projection displays, resulting in a limited user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a display module and electronic device to address the issue of a monotonous control panel experience.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a display module, including:

[0006] The control panel has multiple button areas on its surface, and each button area has a corresponding printed pattern.

[0007] An adjustment assembly includes a drive mechanism and a light-transmitting element, the light-transmitting element being disposed on the side of the control panel facing away from the button area, and the drive mechanism being pulsatorically connected to the light-transmitting element; and

[0008] The light source assembly includes a first light-emitting element and a second light-emitting element. The emitted light from the first light-emitting element and the second light-emitting element can penetrate at least a portion of the light-transmitting element, and the emitted light from the first light-emitting element can induce the pattern in the button area to light up, so that the display module has multiple display modes.

[0009] Through the above design, the emitted light from the first light-emitting element can induce the pattern in the button area to emit light, and the emitted light from the second light-emitting element can project the hollowed-out pattern of the hollowed-out section onto the control panel, thereby cooperating with the light-transmitting element to realize multiple operation display modes.

[0010] In one embodiment of the first aspect, the light-transmitting element includes a transparent segment and a hollow segment. The driving mechanism is controlled to move one of the transparent segment and the hollow segment to the side of the control panel opposite to the button area. The emitted light of the first light-emitting element can penetrate the transparent segment or the hollow segment and induce the pattern of the button area to light up. The emitted light of the second light-emitting element can penetrate the hollow segment and shine on the button area.

[0011] Through the above design, the display module can achieve multiple operation display modes by switching between the transparent segment and the hollow segment.

[0012] In one embodiment of the first aspect, the display module has a first operating state. When the display module is in the first operating state, the transparent segment is located on the side of the control panel opposite to the button area. The pattern is formed by printing with a photosensitive material. The first light-emitting element emits light, and the emitted light from the first light-emitting element penetrates the transparent segment and induces the pattern to light up.

[0013] With the above design, the pattern in the button area emits light when illuminated by the first light-emitting element, thereby displaying the corresponding operation pattern, which facilitates intuitive operation by the user.

[0014] In one embodiment of the first aspect, the pattern is formed by printing with a photosensitive material.

[0015] Through the above design, the pattern formed by printing with photosensitive material can be illuminated by a set light source.

[0016] In one embodiment of the first aspect, the first light-emitting element is an ultraviolet lamp.

[0017] Through the above design, the first light-emitting element can emit ultraviolet light to the control panel, thereby exciting the photosensitive material pattern to emit light and display.

[0018] In one embodiment of the first aspect, the display module has a second operating state. When the display module is in the second operating state, the cutout section is located on the side of the control panel facing away from the button area, and the second light-emitting element emits light. The emitted light from the second light-emitting element penetrates the cutout section and illuminates the button area.

[0019] Through the above design, most of the light from the second light-emitting element is absorbed by the black background of the hollow section and cannot reach the control panel. However, some light can pass through the hollow section and shine onto the control panel, projecting the hollow button shape onto the control panel. Illuminated button patterns appear on the button area on the outside of the control panel, realizing the user's button operation experience.

[0020] In one embodiment of the first aspect, the display module has a third operating state. When the display module is in the third operating state, the cutout section is located on the side of the control panel opposite to the button area. The first light-emitting element and the second light-emitting element emit light simultaneously. The emitted light from the first light-emitting element penetrates the cutout section and induces the pattern to light up. The emitted light from the second light-emitting element penetrates the cutout section and illuminates the button area.

[0021] Through the above design, the ultraviolet light emitted by the first light-emitting element penetrates into the pattern of the button area on the outside of the control panel. The pattern formed by the photosensitive material is illuminated by the light from the first light-emitting element. At the same time, the white light emitted by the second light-emitting element can pass through the hollow section and shine onto the control panel, projecting the hollow button shape onto the control panel, further improving the display brightness of the pattern of the button area on the outside of the control panel and enhancing the user experience.

[0022] In one embodiment of the first aspect, the drive mechanism includes a motor and two oppositely arranged rollers, the two rollers being connected to both ends of the light-transmitting element, and the motor being drively connected to at least one of the rollers to drive the rollers to wind up the light-transmitting element.

[0023] Through the above design, the rotation of the drum can be performed under the drive of the motor, thereby realizing the winding of the light-transmitting component and satisfying the switching of the operation state of the display module.

[0024] In one embodiment of the first aspect, the drum is provided with a coil spring.

[0025] With the above design, when the motor stops working, the drum automatically returns to its original position under the action of the coil spring, thereby pulling the light-transmitting component and realizing the state switching of the light-transmitting component.

[0026] In one embodiment of the first aspect, the light source assembly further includes a circuit board, on which both the first light-emitting element and the second light-emitting element are mounted.

[0027] The above design enables automatic light emission drive for the first and second light-emitting components.

[0028] In one embodiment of the first aspect, the light source assembly further includes a lampshade covering the side of the circuit board where the first light-emitting element and the second light-emitting element are located, and the light-transmitting element is disposed on the side of the lampshade facing away from the circuit board.

[0029] The above design is used to assemble and fix the circuit board and the adjustment component, and to protect the first light-emitting element and the second light-emitting element.

[0030] Secondly, embodiments of this application also provide an electronic device, including the display module described in any of the above embodiments.

[0031] Through the above design, the electronic device can provide users with a variety of operating experiences through the display module.

[0032] Compared to related technologies, the beneficial effects of this application are as follows: This application provides a display module and electronic device that can provide multiple display operation experiences. The display module includes a control panel, an adjustment component, and a light source component. The control panel surface has multiple button areas with printed patterns. The adjustment component includes a driving mechanism and a light-transmitting element, with the light-transmitting element located on the back of the control panel. The light source component includes a first light-emitting element and a second light-emitting element, and the light from the first and second light-emitting elements passes through the light-transmitting element to illuminate the button areas of the control panel. In this way, users can experience multiple operation modes. For example, when the first light-emitting element is selected, the light from the first light-emitting element penetrates the light-transmitting area, inducing the patterns on the button areas to light up. Or, when the second light-emitting element is selected, the light from the second light-emitting element passes through the cutout section, projecting the cutout pattern onto the button areas, thus achieving multiple user operation experiences.

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the term "and / or" appears, "and / or" merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] In related technologies, the display methods of control panels for various electrical appliances differ significantly depending on the price range. Low-end products often use screen printing or laser engraving due to cost considerations. The advantage is low cost, but the disadvantage is a mediocre user experience, and over time, users' fingers will wear down the button displays, causing operational incompatibility. Mid-range products often use semi-transparent control panels with an internal membrane. When the device is off, the bottom light source is off, and the entire control panel displays no information. When the device is on, LED lights illuminate the membrane, projecting the information onto the control panel. High-end products often use transparent laser-engraved function buttons or a large single membrane, enabling two display modes: screen-off and screen-on. The control panel is sophisticated and offers a good user experience, but the cost is higher. Therefore, due to strict price controls, different users can only experience one operating mode, forcibly differentiating their operating experience, which is detrimental to consumer rights.

[0049] See Figure 1 As shown, in order to improve the above problems, the embodiments of this application provide a display module 100, which can be used to display operations on the control panel 110 of various electronic devices, thereby improving the user experience.

[0050] Continue reading Figure 2 As shown, specifically, the display module 100 includes a control panel 110, an adjustment component 120, and a light source component 130. The control panel 110 displays corresponding device operation information, the light source component 130 emits light to the control panel 110 to illuminate it during operation, and the adjustment component 120 adjusts different display modes according to the user's experience mode settings, working in conjunction with the light source component 130 to achieve different operation modes.

[0051] Furthermore, the outer surface of the control panel 110 is provided with multiple button areas 111, each button area 111 having a corresponding printed pattern.

[0052] Specifically, the outer surface of the control panel 110 serves as the operation control interface of the display module 100. It can be made of a semi-transparent material, allowing it to remain black when not in operation and to emit light when in operation. Each button area 111 can send corresponding control commands to the device upon user touch and press, adjusting the device's operating status and mode. The surface of the button area 111 is printed with patterns using photosensitive material, forming corresponding control symbols or text. In operation, the patterns on the button area 111 illuminate, enhancing the user experience. Conversely, in non-operational mode, the printed patterns on the photosensitive material are invisible to the human eye under natural light, and the control panel 110 remains completely black.

[0053] Continue reading Figure 3 As shown, the adjustment component 120 includes a drive mechanism 122 and a light-transmitting element 121. The light-transmitting element 121 is disposed on the side of the control panel 110 away from the button area 111 and includes a transparent section 1211 and a hollow section 1212. The drive mechanism 122 is connected to the light-transmitting element 121 and drives one of the transparent section 1211 and the hollow section 1212 to be located on the side of the control panel 110 away from the button area 111.

[0054] Specifically, the light-transmitting element 121 is disposed on the bottom side of the control panel 110 and has a film structure. The transparent section 1211 can be a transparent plastic film structure to allow light emitted from a common light source to penetrate the transparent section 1211 and shine onto the control panel 110. The perforated section 1212 can be a sheet-like object with a black background, on which multiple perforations are provided through, and the shape of the perforations is the same as the printed pattern of the button area 111, so that under the illumination of light, the perforated shape of the perforated section 1212 is projected onto the control panel 110, which is convenient for the user to observe and operate.

[0055] Continue reading Figure 4 and Figure 5 As shown, the light source assembly 130 includes a first light-emitting element 131 and a second light-emitting element 132. The light emitted by the first light-emitting element 131 can penetrate the transparent section 1211 and induce the pattern of the button area 111 to light up. The light emitted by the second light-emitting element 132 can penetrate the hollow section 1212 and shine on the button area 111.

[0056] Specifically, both the first light-emitting element 131 and the second light-emitting element 132 are LED (light-emitting diode) beads, enabling single-emitting-emitting-emitting-operation or simultaneous operation of both elements under user control. The number of the first light-emitting element 131 and the second light-emitting element 132 is the same as the number of button areas 111 on the control panel 110, and the first light-emitting element 131 and the second light-emitting element 132 are located on the same vertical line as the corresponding button areas 111, thereby achieving luminous display of the button areas 111. The emitted light from the first light-emitting element 131 can induce the photosensitive material pattern of the button area 111 to emit light, and the emitted light from the second light-emitting element 132 can project the hollowed-out pattern of the hollowed-out section 1212 onto the control panel 110, thus cooperating with the light-transmitting element 121 to achieve multiple operation display modes.

[0057] In one specific embodiment, the display module 100 has a first operating state. When the display module 100 is in the first operating state, the transparent segment 1211 is located on the side of the control panel 110 opposite to the button area 111. The pattern is formed by printing with photosensitive material. The first light-emitting element 131 emits light, and the emitted light of the first light-emitting element 131 penetrates the transparent segment 1211 and induces the pattern to light up.

[0058] Specifically, the user selects the first operating state display mode of the control panel 110 through mode selection. At this time, driven by the drive mechanism 122, the transparent segment 1211 of the light-transmitting element 121 is located between the light source assembly 130 and the control panel 110. The first light-emitting element 131 emits light, and the second light-emitting element 132 is turned off, so that the emitted light from the first light-emitting element 131 penetrates the transparent segment 1211 and shines on the control panel 110. Due to the semi-transparent nature of the control panel 110, light can penetrate the control panel 110 from the bottom side and illuminate the pattern of the button area 111 on the outside of the control panel 110. The pattern formed by the photosensitive material is illuminated by the light from the first light-emitting element 131, thereby displaying the corresponding operation pattern, which facilitates intuitive operation by the user.

[0059] For example, the photosensitive material in this application can be phosphor, phosphorescent powder, quantum well material, etc., and can be selected according to actual needs, as long as it meets the requirements for light reception and display of the pattern.

[0060] Preferably, the first light-emitting element 131 is an ultraviolet LED lamp, which can emit ultraviolet light to the control panel 110, thereby stimulating the photosensitive material pattern to emit light and display.

[0061] Furthermore, the display module 100 also has a second operating state. When the display module 100 is in the second operating state, the hollow section 1212 is located on the side of the control panel 110 facing away from the button area 111, and the second light-emitting element 132 emits light. The emitted light of the second light-emitting element 132 penetrates the hollow section 1212 and illuminates the button area 111.

[0062] Specifically, the second light-emitting element 132 is a white LED light. The user selects the second operating state display mode of the control panel 110 through mode selection. At this time, driven by the drive mechanism 122, the hollow section 1212 of the light-transmitting element 121 is located between the light source assembly 130 and the control panel 110. The first light-emitting element 131 is turned off, and the second light-emitting element 132 illuminates. During the operation of the second light-emitting element 132, most of the light is absorbed by the black background of the hollow section 1212 and cannot reach the control panel 110. However, some light can pass through the hollow section 1212 and shine onto the control panel 110, and continue to pass through the semi-transparent control panel 110, projecting the hollow button shape onto the control panel 110. Illuminated button patterns appear on the outer button area 111 of the control panel 110, realizing the user's button operation experience.

[0063] Furthermore, the display module 100 has a third operating state. When the display module 100 is in the third operating state, the hollow section 1212 is located on the side of the control panel 110 facing away from the button area 111. The first light-emitting element 131 and the second light-emitting element 132 emit light simultaneously. The light emitted by the first light-emitting element 131 penetrates the hollow section 1212 and induces the pattern to light up. The light emitted by the second light-emitting element 132 penetrates the hollow section 1212 and illuminates the button area 111.

[0064] Specifically, the user selects the third operating state display mode of the control panel 110 through mode selection. At this time, driven by the drive mechanism 122, the hollow section 1212 of the light-transmitting element 121 is located between the light source assembly 130 and the control panel 110. The first light-emitting element 131 and the second light-emitting element 132 emit light simultaneously, and most of the emitted light from the first light-emitting element 131 and the second light-emitting element 132 is absorbed by the black film of the hollow section 1212, and can only pass through the hollow section 1212 to shine onto the control panel 110. The ultraviolet light emitted by the first light-emitting element 131 penetrates to the pattern of the button area 111 on the outside of the control panel 110. The pattern formed by the photosensitive material is illuminated by the light from the first light-emitting element 131, thereby displaying the corresponding operation pattern. At the same time, the white light emitted by the second light-emitting element 132 can pass through the hollow section 1212 and shine onto the control panel 110, projecting the hollow button shape onto the control panel 110, further improving the display brightness of the pattern in the button area 111 on the outside of the control panel 110, and improving the user experience.

[0065] Continue reading Figure 6 As shown, in some embodiments, the drive mechanism 122 includes a motor 12211 and two rollers 1222 arranged opposite to each other. The two rollers 1222 are respectively connected to both ends of the light-transmitting element 121. The motor 12211 is drivenly connected to at least one roller 1222 to drive the roller 1222 to wind up the light-transmitting element 121.

[0066] Specifically, two rollers 1222 are respectively disposed on opposite sides of the display module 100, and after being connected to the light-transmitting element 121, they rotate to wind up the light-transmitting element 121. It can be understood that when winding up at one end of the transparent section 1211, the transparent section 1211 of the light-transmitting element 121 is wound onto the roller 1222, while the hollow section 1212 lies flat between the light source assembly 130 and the control panel 110, thus satisfying the second and third operating states of the display module 100. When winding up at one end of the hollow section 1212, the hollow section 1212 of the light-transmitting element 121 is wound onto the roller 1222, while the transparent section 1211 lies flat between the light source assembly 130 and the control panel 110, thus satisfying the first operating state of the display module 100. The motor 12211 is connected to the drum 1222 for transmission, so that the drum 1222 can be rotated under the drive of the motor 12211 to realize the winding operation of the light-transmitting component 121 and meet the switching of the operation status of the display module 100.

[0067] Furthermore, a coil spring is provided inside the roll 1222. The coil spring can continuously provide a large restoring force in a confined space. By providing a coil spring inside the roll 1222, the roll 1222 has a strong restoring force. In this embodiment, the motor 12211 only needs to be connected to one roll 1222. When the motor 12211 drives the roll 1222 to rotate, the light-transmitting element 121 of the other roll 1222 is pulled, causing the other roll 1222 to rotate. When the motor 12211 stops operating, the roll 1222 automatically returns to its original position under the action of the coil spring, thereby pulling the light-transmitting element 121. It can be understood that one restoring stroke of the coil spring is the same as the length of the transparent section 1211 or the hollowed-out section 1212, thus satisfying the state switching of the display module 100.

[0068] In some embodiments, the light source assembly 130 further includes a circuit board 133, on which the first light-emitting element 131 and the second light-emitting element 132 are both mounted.

[0069] Specifically, the circuit board 133 is a PCB (Printed Circuit Board). The first light-emitting element 131 and the second light-emitting element 132 are embedded on the circuit board 133 by a soldering process and are connected to the circuit of the circuit board 133. Thus, the automatic light-emitting drive of the first light-emitting element 131 and the second light-emitting element 132 can be realized through the chip control of the circuit board 133.

[0070] In some embodiments, the light source assembly 130 further includes a lampshade 134, which covers the side of the circuit board 133 where the first light-emitting element 131 and the second light-emitting element 132 are provided, and a light-transmitting element 121 is laid on the side of the lampshade 134 facing away from the circuit board 133.

[0071] Specifically, the lampshade 134 is located on the bottom side of the control panel 110, and two rollers 1222 are respectively installed on both sides of the lampshade 134 to fix the adjustment assembly 120. Through holes 1341 are provided at positions corresponding to each button area 111 on the lampshade 134, so that the emitted light from the first light-emitting element 131 and the second light-emitting element 132 can shine onto the control panel 110 through the through holes 1341.

[0072] Furthermore, springs 135 are provided on the periphery of the first light-emitting element 131 and the second light-emitting element 132. When assembled with the lamp cover 134, the springs 135 are inserted into the through holes 1341 of the lamp cover 134, thereby facilitating the assembly and positioning of the circuit board 133 and the lamp cover 134, and protecting the first light-emitting element 131 and the second light-emitting element 132.

[0073] Embodiments of this application also provide an electronic device, including the display module 100 in any of the above embodiments.

[0074] For example, the electronic device may be a tower fan, table fan, cleaning robot, vacuum cleaner, refrigerator, or other household appliance, and provides users with a variety of operating experiences through the display module 100.

[0075] This embodiment has the display module 100 of any of the above embodiments, and therefore has all the beneficial effects of the display module 100 of any of the above embodiments, which will not be described in detail here.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
