The display device further includes a plurality of first lamp groups 111, where the plurality of first lamp groups 111 are disposed in each display lamp slot 110 in a one-to-one correspondence manner, and are used for independently lighting each display lamp slot 110. The second lamp group 121 is provided in the accommodation groove 120, and when the second lamp group 121 is lighted, the light guide portion 210 emits light, and thus the light guide plate 200 is lighted as a whole.

Specifically, the light guide plate 200 of the present embodiment is made of PS, PC, PVC, or other materials, and has high transparency. The light guide plate 200 specifically includes a light guide portion 210 having a larger thickness, and a light transmitting portion 220 having a smaller thickness than the light guide portion 210, wherein the light guide portion 210 is embedded in the accommodating groove 120, and the light transmitting portion 220 covers the open side of each display lamp groove 110. At least the inside of the light guide portion 210 of the light guide plate 200 is added with a light diffusing powder, which diverges the light irradiated to the light guide portion 210 and guides the light to the light transmitting portion 220 of the light guide plate 200. Thus, only the second lamp group 121 below the light guide portion 210 is lighted, and the entire light guide plate 200 can be lighted.

In a specific scheme of this embodiment, a light film (not shown in the figure) is adhered to the upper side of the light guide plate 200, and a plurality of display icons are printed on the light film, where the display icons are in one-to-one correspondence with the display lamp slots 110 below the light guide plate 200.

The icon layer has a plurality of display icons corresponding to the display lamp slots 110 one by one, and a colored background pattern outside the display icons, and the light guide layer is locally protruded downwards to form a light guide part 210 for realizing light guide to the whole light guide plate 200, and the protective layer covers the upper side of the icon layer to prevent the display icons and the colored background pattern on the icon layer from being scratched and falling off.

In the above-described configuration, as shown by the dotted arrow in fig. 3, when the second lamp group 121 of the display device is lighted, the entire lighting of the light guide plate 200 can be realized by the light guiding effect of the light guide portion 210, thereby integrally lighting the color background pattern. As shown by solid arrows in fig. 3, the corresponding area of the light guide plate 200 can be partially illuminated by matching with the illumination of the first light set 111, so that the brightness of the corresponding displayed icon is improved compared with other displayed icons, and corresponding information is prompted to the user through contrast of brightness and darkness. The finally presented display interface has a large-area background pattern, forms contrast display effects with different brightness, can enrich the picture texture of the display interface, has a display effect similar to an electronic display screen, and improves the use experience of users.

In the present embodiment, the greater the thickness of the light guide plate 200 at the light guide portion 210, the stronger the brightness of the entire light guide plate 200 when the second lamp group 121 is lighted. The receiving groove 120 is provided on the display panel 100 to implement the embedded installation of the light guide part 210, and further the second lamp group 121 may be provided under the light guide plate 200 together with the first lamp group 111. In this way, the first lamp set 111 and the second lamp set 121 may be disposed on the same circuit board, which is advantageous for simplifying a wiring structure for connecting the display device with the power supply device or the control device.

In this embodiment, the first lamp set 111 and the second lamp set 121 are each composed of a plurality of LED lamp beads, and the LED lamp beads are disposed on the bottom walls of the display lamp groove 110 and the accommodating groove 120.

In a further aspect of this embodiment, the lower surface of the light guiding portion 210 has a light guiding structure for guiding light to the light guiding plate 200 covering the area of the display lamp socket 110, that is, the light transmitting portion 220.

Specifically, the light guiding structure controls the light emitted by the second lamp set 121 to deflect towards the direction of the light transmitting portion 220 by utilizing the refraction effect when the light passes through the lower surface of the light guiding portion 210, so that the second lamp set 121 below the light guiding portion 210 can be used to illuminate the whole light guiding plate 200 more effectively.

Further, in the display device provided in the present embodiment, the display lamp sockets 110 are arranged in at least one row along the first direction a and at least two columns along the second direction B perpendicular to the first direction a on the display panel 100. The receiving groove 120 is extended in the first direction a, and the extending length of the receiving groove 120 is the same as the total length of the display lamp grooves 110 arranged in a row. Each display lamp recess 110 is located on the same side of the receiving recess 120.

The light guide plate 200 has two first edges 201 extending in a first direction a and disposed opposite thereto, and two second edges 202 extending in a second direction B and disposed opposite thereto. In order to match the layout of the display lamp slots 110 and the receiving slots 120 on the display panel 100, the light guide 210 is disposed on the light guide plate 200 near one of the first edges 201, and extends from one of the second edges 202 of the light guide plate 200 to the other second edge 202 along the first direction a.

In a specific scheme of this embodiment, six display lamp slots 110 are disposed on the display panel 100, and the six display lamp slots 110 are arranged in a two-row three-column arrangement mode. The receiving groove 120 is provided at the forefront side of the display panel 100, that is, six display lamp grooves 110 are all located at the rear side of the receiving groove 120.

Accordingly, the light guide 210 is disposed near the front first edge 201 of the light guide plate 200, and is inserted into the receiving groove 120. When the second lamp group 121 provided on the bottom wall of the receiving groove 120 is lighted, light may be guided to the rear side by the light guide portion 210 such that the light transmitting portion 220 positioned at the rear side of the light guide portion 210 is also lighted.

In a further aspect of this embodiment, the lower surface of the light guiding portion 210 is a concave curved surface to form the light guiding structure, and the concave depth of the curved surface gradually increases from two sides of the light guiding portion 210 to the middle.

Preferably, as shown in fig. 3 and 4, the lower surface of the light guiding portion 210 is an arc-shaped curved surface extending from one side of the light guiding portion 210 to the other side in an arc shape, and the central axis thereof is parallel to the extending direction of the light guiding portion 210 (i.e., the first direction a in fig. 1 and 2).

More preferably, the central axis of the curved surface is lower than the plane of the second lamp set 121.

In the above-described aspect, the lower surface of the light guide portion 210 is an arc-shaped curved surface, so that the light guide portion 210 has a concave lens-like structure. When the second lamp set 121 is turned on, the curved surface diverges the incident light, and the light emitted by the second lamp set 121 is deflected in the direction of the light-transmitting portion 220 when entering the light-guiding portion 210 from the lower surface of the light-guiding portion 210. Further, the light-transmitting portion 220 can have a certain brightness by utilizing the dispersion effect of the light-scattering powder in the light-guiding portion 210 on the light.

Fig. 5 is a diagram showing the effect of a display interface presented by the display device adopting the structure of the present embodiment. The display device is applied to the washing machine, and can interact with a user when the user sets a washing program to prompt the user of the type of the washing program selected currently.

Specifically, the display interface shown in fig. 5 has eight display icons arranged in two rows and four columns, and the bottom letter "< procedure >" corresponds to the accommodation groove 120 and the second lamp set 121 on the display panel 100. When the user performs the washing course setting, the second lamp set 121 maintains a normally-on state, so that the background pattern in fig. 5 is entirely lighted, thereby providing a rich picture texture. When a user selects a washing course, such as wool washing course, the first lamp set 111 corresponding to the lower part of the displayed icon "wool" is lighted, and the light emitted by the first lamp set 111 is directly transmitted through the light guide plate 200 to further illuminate the area where the displayed icon "wool" is located. The user can determine that the currently selected washing program is the wool washing program by displaying the icon 'wool' on the display interface with higher brightness than other displayed icons.

In a further scheme of the embodiment, the display panel 100 is provided with a concave sinking groove 130, a partition plate 131 is arranged in the sinking groove 130, and the interior of the sinking groove 130 is partitioned into a containing groove 120 and a plurality of display lamp grooves 110. The upper edge of the partition plate 131 is lower than the upper surface of the display panel 100. The light guide plate 200 is installed in the sink 130, and an upper surface of the light guide plate 200 is flush with the surface of the display panel 100 at the outer circumference of the sink 130.

In the above-described scheme, the light guide plate 200 is integrally insert-mounted on the display panel 100 such that the light guide plate 200 is flush with the upper surface of the display panel 100. Therefore, the upper surface of the display device for displaying the display content is integrally flat and attractive.

Particularly, when a lamp film printed with display contents is to be attached to the display panel 100, since not all display contents are located in the area where the light guide plate 200 is located, for example, the display panel 100 has a digital display area outside the sink 130, it is also necessary to attach the lamp film to cover. The light guide plate 200 is provided in a structure of being flush with the upper surface of the display panel 100, a lamp film having a size matching does not need to be cut out separately for the region of the light guide plate 200, but a lamp film having a size matching with the entire size of the display panel 100 can be directly used, and the lamp film can be smoothly attached to the display panel 100. On the one hand, the assembly process of the display device is simplified, and on the other hand, a complete lamp film is directly adhered on the display panel 100, so that the whole attractive and elegant appearance of the display device is facilitated.

In a preferred embodiment of the present embodiment, the side wall of the sink 130 is provided with a limiting groove 132, and the light guide plate 200 is provided with a limiting protrusion 230. The limit protrusions 230 on the light guide plate 200 are installed in a matched manner with the limit grooves 132 on the side walls of the sink 130.

In detail, one limiting protrusion 230 is disposed on each of the two first edges 201 and the two second edges 202 of the light guide plate 200, and the limiting protrusion 230 is disposed at the center of the first edge 201 or the second edge 202 and is flush with the upper surface of the light guide plate 200. The limit grooves 132 are disposed at the upper side openings of the sink 130 and correspond to the positions of the limit protrusions 230 one by one.

In this embodiment, when assembling the display device, it is necessary to mount the light guide portion 210 in alignment with the opening of the accommodating groove 120. However, the transverse cross-sectional dimension of the light guide portion 210 is not completely matched with the opening dimension of the accommodating groove 120, so that the light guide portion 210 and the accommodating groove 120 can be matched for auxiliary positioning, and the light guide plate 200 is fixed by matching the shape of the sinking groove 130 and the light guide plate 200 when the light guide plate is finally installed in place. Meanwhile, through the arrangement of the limiting protrusion 230 and the limiting groove 132, the mounting position of the light guide plate 200 can be further fixed, the light guide plate 200 is prevented from shaking on the display panel 100, and the mounting stability of the light guide plate 200 is improved.

In another preferred scheme of this embodiment, the setting positions of the limiting groove and the limiting protrusion may be exchanged, that is, the limiting protrusion is disposed on the side wall of the sink groove, and the corresponding limiting groove is disposed on the light guide plate. By adopting the structure, the limiting protrusion and the limiting groove can be used for limiting and matching, and the fixing effect is achieved on the light guide plate after the light guide plate is installed.

In this embodiment, the light guide plate 200 is embedded in the display panel 100 of the display device, and the light emitted from the second lamp set 121 below the light guide plate 210 is guided to other areas of the light guide plate 200 by the light guide portion 210 partially protruding on the light guide plate 200, so that the light guide plate 200 can be lit up as a whole. And the first lamp set 111 is matched for further lighting the local area on the light guide plate 200, so that a richer picture sense display effect can be realized through superposition of two light sources, and the use experience of a user is improved.

Example two

As shown in fig. 1 and 6, this embodiment differs from the first embodiment in that: the lower surface of the light guide 210 is a horizontal plane.

In this embodiment, the lower surface of the light guide portion 210 is not provided with a special light guide structure, but is directly configured in a horizontal plane. In comparison with the first embodiment, although the lower surface of the light guide portion 210 is horizontally disposed, the light guide portion 210 cannot refract the incident light, but the light scattering powder added in the light guide portion 210 can diffuse the incident light in the light guide portion 210 by the reflection of the light, so as to guide the light to the light transmitting portion 220, and the light guide plate 200 is illuminated as a whole.

Compared to the first embodiment, since the lower surface of the light guide portion 210 has a horizontal surface structure, it is easier to process and shape.

Example III

As shown in fig. 1 and 7, this embodiment differs from the first embodiment in that: the lower surface of the light guide portion 210 is an inclined surface to form the light guide structure.

Specifically, the inclined surface extends obliquely downward from a side of the light guide 210 away from the display troffer (i.e., left side in fig. 7) toward a direction approaching the display troffer. That is, the thickness of the light guide portion 210 gradually increases from the edge of the light guide plate 200 toward the light transmitting portion 220.

In the above-mentioned scheme, the light emitted by the second lamp set below the light guide portion 210 is incident into the light guide portion 210 in a nearly vertical direction, and when passing through the lower surface of the light guide portion 210, the light is refracted and deflected in the direction of the light transmitting portion 220 (i.e. the right side in fig. 7), so that the light can be guided to the light transmitting portion 220, and the whole light transmitting portion 220 can be illuminated by the light emitted by the second lamp set.

Further, the included angle between the inclined surface and the horizontal plane can be adjusted according to the deflection angle of the required light. For example, when the size of the light guide plate 200 in the second direction B is larger, the angle between the inclined surface and the horizontal surface needs to be set larger in order to ensure that the light can be guided to the region of the light guide plate 200 away from the light guide portion 210.

In this embodiment, the inclined surface is adopted as the light guiding structure instead of the curved surface in the first embodiment, so that the effect of directing the light to the specific Fang Xiangdao light can be achieved, and the brightness of the whole light guiding plate 200 illuminated when the second lamp group is lighted is further enhanced.

Example IV

As shown in fig. 1, 8 to 10, the present embodiment is different from the first embodiment in that: the display lamp sockets 110 are arranged on both sides of the accommodating groove 120, the light guide portion 210 is disposed in the middle of the light guide plate 200, and light is guided to both sides of the light guide portion 210.

Specifically, in the present embodiment, the display lamp sockets 110 are arranged in at least two rows along the first direction a and at least two columns along the second direction B perpendicular to the first direction a on the display panel 100. The receiving groove 120 extends in the first direction a and is disposed between two adjacent display lamp grooves 110, and the extending length of the receiving groove 120 is the same as the total length of the display lamp grooves 110 arranged in a row.

In this embodiment, the light guide plate 200 also has two first edges extending along the first direction a and disposed opposite to each other, and two second edges extending along the second direction B and disposed opposite to each other. In order to match the layout of the display lamp groove 110 and the receiving groove 120 on the display panel 100, the light guide 210 is disposed at a middle region of the light guide plate 200 and extends from one second edge of the light guide plate 200 to the other second edge along the first direction a.

Fig. 8 shows a specific solution of this embodiment, where six display lamp sockets 110 are disposed on the display panel 100, and the six display lamp sockets 110 are arranged in a two-row three-column arrangement mode. The accommodating groove 120 is disposed between the two rows of display lamp grooves 110, that is, the front side and the rear side of the accommodating groove 120 are respectively provided with one row of display lamp grooves 110.

The middle part of the light guide plate 200 is provided with the light guide part 210 embedded in the accommodating groove 120, when the second lamp set arranged on the bottom wall of the accommodating groove 120 is lighted, the light guide part 210 receives the light rays emitted by the second lamp set and guides light to the front side and the rear side simultaneously, so that the regions of the light guide plate 200 positioned at the front side and the rear side of the light guide part 210 are also illuminated.

Further, the lower surface of the light guiding portion 210 of the light guiding plate 200 in this embodiment is also provided with a light guiding structure, and the refraction effect of the light guiding structure on the light is utilized to enhance the light guiding effect on the front and rear sides of the light guiding portion 210.

As a preferable solution of this embodiment, as shown in fig. 9, the lower surface of the light guiding portion 210 is a concave curved surface to form the light guiding structure, and the concave depth of the curved surface from the front and rear sides of the light guiding portion 210 gradually increases toward the middle.

Further preferably, the lower surface of the light guiding portion 210 is an arc-shaped curved surface that extends from the front side to the rear side of the light guiding portion 210 in an arc shape, and the central axis thereof is parallel to the extending direction of the light guiding portion 210, that is, the first direction a.

More preferably, the central axis of the arc-shaped curved surface is lower than the plane of the second lamp group.

In the above-described aspect, the lower surface of the light guide portion 210 is an arc-shaped curved surface, forming a concave lens-like structure. When the light emitted by the second lamp set passes through the curved surface to be refracted, the light diverges under the action of the curved surface, so that the light guide portion 210 deflects at the front and rear sides. In this way, the light is guided to the area of the light guide plate 200 outside the light guide portion 210, so that the light guide plate 200 is integrally illuminated, and the screen sense of the display interface can be enriched as a background light source.

As another preferable aspect of the present embodiment, as shown in fig. 10, the lower surface of the light guide portion 210 extends obliquely upward from the front side to the rear side of the light guide portion 210, and then extends obliquely downward, thereby forming the light guide structure. That is, the thickness of the light guide 210 gradually decreases from the front side to the rear side, and then gradually increases.

Further preferably, the lower surface of the light guide part 210 has an inverted V-shaped structure. When the light beam emitted from the second lamp set below the light guide portion 210 passes through the lower surface of the light guide portion 210, the light beam near the front side of the light guide portion 210 is refracted and deflected in the front side, the light beam near the rear side of the light guide portion 210 is refracted and deflected in the rear side, and the light beams are respectively guided to the front side and the rear side of the light guide plate 200, so that the whole light guide plate 200 is illuminated by the light beam emitted from the second lamp set.

In this embodiment, the display lamp slots 110 are disposed on the front and rear sides of the accommodating slot 120 on the display panel 100, and the lower surface of the light guiding portion 210 has an arc-shaped curved surface or an inverted V-shaped structure, so that the light can be guided to the front and rear sides of the light guiding portion 210 by the refraction of the light. The light guide plate 200 is integrally illuminated as a background light source, realizing a display effect with a richer sense of picture.

Example five

As shown in fig. 1 and 11, this embodiment differs from the first embodiment in that: the display lamp groove 110 is circumferentially arranged on the outer periphery of the accommodating groove 120, and the light guide part is correspondingly arranged in the central area of the light guide plate 200, and is arranged outside the light guide part 210, namely, zhou Daoguang.

Specifically, in this embodiment, the plurality of display lamp slots 110 surrounds the outer side Zhou Buju of the accommodating slot 120 to form at least one circle, the light guiding portion is correspondingly disposed in the middle area of the light guiding plate 200, and the outer periphery of the light guiding portion is a light transmitting portion with a thickness smaller than that of the light guiding portion, so as to cover the open side of the display lamp slots 110.

Fig. 11 shows a specific solution of this embodiment, in which eight display lamp slots 110 are disposed on the display panel 100, and the eight display lamp slots 110 are disposed on the outer periphery of the accommodating slot 120 and just encircle a circle. Accordingly, a light guide portion protruding downward is provided at the center of the light guide plate 200 in this embodiment, and is inserted into the receiving groove 120.

When the second lamp set disposed on the bottom wall of the accommodating groove 120 is turned on, the light guiding portion receives the light emitted by the second lamp set and guides the light to the periphery at the same time, so that the area of the light guiding plate 200 located at the periphery of the light guiding portion is also illuminated.

Further, in this embodiment, the lower surface of the light guiding portion is a concave curved surface to form a light guiding structure. The concave depth of the concave curved surface gradually increases from the peripheral area to the middle area.

Preferably, the lower surface of the light guiding portion is a sphere, and a center of the sphere is preferably lower than a plane of the second lamp set.

In the above-mentioned scheme, the lower surface of the light guiding portion is spherical, so that the light guiding portion 210 has a concave lens-like structure, and can diverge the incident light. When the second lamp group below the light guide part is lighted, the incident light rays approaching to the vertical direction pass through the spherical surface and then deflect towards the peripheral direction of the light guide part, so that the effect of guiding the light rays to the periphery and enabling the light guide plate 200 to be integrally illuminated can be realized.

In this embodiment, the display lamp slots 110 on the display panel 100 are arranged around the outer periphery of the accommodating slot 120, and the light guide portions are correspondingly arranged in the central area of the light guide plate 200 to face outwards Zhou Daoguang, so that the light guide plate 200 can be integrally illuminated, and the display effect of enriching the picture feeling can be achieved by using the light source.

The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the utility model, may be made by those skilled in the art without departing from the scope of the utility model.
