Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.

A display device according to an embodiment of the present invention will be described below with reference to fig. 1 to 6.

The display device may be applied to various electric appliances, including but not limited to: electric rice cooker, water purifier, coffee machine, food processor, washing machine, water heater, refrigerator or vending machine, etc.

As shown in fig. 1, the display device includes: a light-transmitting plate 220, a texture layer 121, a pattern layer 130, a light-shielding layer 140 and a light-emitting device 300.

The texture layer 121, the pattern layer 130, and the light-shielding layer 140 are disposed on the outer surface side of the light-transmitting plate 220, and the light-emitting device 300 is disposed on the inner surface side of the light-transmitting plate 220.

The light-transmitting plate 220 can transmit light, the light is emitted from the light-emitting device 300 inside, at least a portion of the light is transmitted through the light-transmitting plate 220 and is emitted onto the pattern of the pattern layer 130, and the pattern forms a larger contrast difference with other surrounding areas, so that the user can clearly see the pattern.

The light-transmitting panel 220 forms at least part of the housing of the apparatus to which the display device belongs, in other words, the light-transmitting panel 220 may be part of the housing of the apparatus to which the display device belongs.

It should be noted that, in the related art, it is necessary to design an independent substrate to carry the pattern layer 130, the light shielding layer 140, and the like, so that when the display device is assembled to the electrical apparatus, an independent assembly structure of the substrate needs to be considered, and a sufficiently large installation position needs to be reserved at a position where the display device is located, which affects a spatial layout design of the electrical apparatus.

In the display device according to the embodiment of the present invention, the pattern layer 130 and the light shielding layer 140 are directly disposed on the device housing, so that a part of the assembly structure at the position can be omitted, and the occupied installation space is smaller.

The pattern layer 130 includes a plurality of patterns, which may be marks such as figures or words, such as a washing machine, for example, the pattern layer 130 may include patterns for characterizing washing and dewatering, and words for characterizing water amount; in the case of a rice cooker, the pattern layer 130 may include a pattern for representing a cooking mode. Each pattern may correspond to a key, for example the light emitting device 300 inside the pattern may be provided with corresponding control keys.

The light-shielding layer 140 is used to cooperate with the pattern layer 130 to shield other regions of the pattern layer 130 where no pattern is disposed, so as to prevent light from passing through these regions, and thus when the light-emitting device 300 emits light, only the pattern is illuminated to contrast with other regions.

The light-shielding layer 140 includes a light-transmitting region disposed opposite to the pattern on the pattern layer 130.

Thus, the light emitted from the light emitting device 300 can be irradiated to the pattern of the pattern layer 130 through the light transmitting region of the light shielding layer 140, so that the pattern is lighted; the other regions of the pattern layer 130 where no pattern is provided are shielded by the light-shielding layer 140 and are not lit.

It should be noted that, in the actual process, it is necessary to ensure that the pattern of the pattern layer 130 is aligned with the transparent region of the light shielding layer 140, so as to prevent incomplete pattern display or light leakage at the edge of the pattern.

In actual processing, the light-transmitting area of the light-shielding layer 140 may be set smaller than the pattern of the pattern layer 130, that is, the light-shielding layer 140 may be set at a blank position relative to the pattern layer 130, so as to reduce the requirement of alignment accuracy between the pattern layer 130 and the light-shielding layer 140 and ensure that the edge of the pattern layer 130 is not light-tight.

The light-shielding layer 140 is attached to the outer surface of the light-transmitting plate 220, and it is understood that the pattern corresponding to the light-transmitting region of the light-shielding layer 140 in the pattern layer 130 may also be attached to the outer surface of the light-transmitting plate 220. The outer surface of the light-transmitting panel 220 refers to the side of the light-transmitting panel 220 facing the outer surface of the electrical device.

The pattern layer 130 and the light-shielding layer 140 are disposed on the back surface of the texture layer 121, the front surface of the texture layer 121 faces a user, and the texture layer 121 serves to shield the pattern layer 130 therebelow, so that when the light-emitting device 300 does not emit light, the pattern of the pattern layer 130 is displayed in black when the pattern layer 130 is viewed through the texture layer 121.

The light emitting device 300 is installed on the inner surface of the transparent plate 220, and when the light emitting device 300 is powered on, it can emit light to the transparent plate 220.

Correspondingly, the irradiation direction of the light is as follows: the light emitting device 300, the transparent plate 220, the light shielding layer 140, the pattern layer 130 and the texture layer 121.

In the related art, the pattern layer 130 and the light-shielding layer 140 are respectively disposed on both sides of the substrate. In this way, the substrate needs to be pasted on both sides by the glue 160, and the alignment between the light-shielding layer 140 and the pattern layer 130 is ensured, which is difficult to operate and difficult to ensure the yield.

The display device of the utility model comprises a texture layer 121, a pattern layer 130, a light shielding layer 140 and a transparent plate 220 in sequence from outside to inside, i.e. the pattern layer 130 and the light shielding layer 140 are arranged on the same side of the transparent plate 220. Therefore, the process of surface mounting can be reduced, and the production efficiency during processing is improved.

On the other hand, the texture layer 121, the pattern layer 130 and the light-shielding layer 140 are all disposed on the outer surface side of the light-transmitting plate 220, so that the number of film sheets can be reduced, which can reduce the power of the light-emitting device 300 or reduce the brightness of the light-emitting device 300, and prolong the life of the light-emitting device 300.

According to the display device provided by the utility model, the texture layer 121, the pattern layer 130 and the light shielding layer 140 are directly arranged on the outer surface of the equipment shell, so that the surface mounting process can be reduced, the production efficiency in processing is improved, part of assembly structures at the positions can be omitted, the occupied installation space is smaller, the shielding effect is good when the whole display device is not lightened, and the pattern is displayed more clearly when the display device is lightened.

In some embodiments, the light shielding layer 140 is adhered to the transparent plate 220. The light-shielding layer 140 may be adhered to the outer surface of the transparent plate 220 by glue 160. The pattern exposed from the light-transmitting region of the light-shielding layer 140 may be adhered to the outer surface of the light-transmitting plate 220.

In actual implementation, the pattern layer 130 may be formed on the back surface of the texture layer 121 by inkjet printing, and the inkjet-formed pattern layer 130 has better definition, color reproducibility, saturation and hiding effect.

The light shielding layer 140 may be an ink layer, the ink layer is silk-screened on the back of the texture layer 121, and then the pattern layer 130 is formed on the back of the texture layer 121 by spray-painting, a pattern is formed in a partial region of the back of the texture layer 121, the light shielding layer 140 is silk-screened on the back of the texture layer 121, a white space is left in a region where the pattern is located, a light transmitting region is formed, and in order to prevent light leakage at the edge of the pattern, the light shielding layer 140 may coincide with the edge of the pattern into a part.

The texture layer 121 includes a plurality of layers, and at least two layers are different in color. Thus, a better fuzzy shielding effect can be achieved.

In some embodiments, the texture layer 121, the pattern layer 130, and the light-shielding layer 140 may be transferred to the light-transmitting plate 220 through a compounding and transfer process.

In the actual processing process, a PET (polyester resin) film may be processed, as shown in fig. 2, the PET film 100 includes a PET layer 110, a texture layer 121, a pattern layer 130, and a light shielding layer 140, and the PET layer 110, the texture layer 121, the pattern layer 130, and the light shielding layer 140 are sequentially stacked.

The process of processing the PET film sheet 100 may include the steps of:

silk-screen printing a texture layer 121 on the back of the PET layer 110, and in the actual processing process, forming the texture layer 121 attached to the back of the PET layer 110 on the back of the PET layer 110 through multi-degree silk-screen printing according to needs;

spraying patterns on the surface of the texture layer 121, which is away from the PET layer 110 (the surface is the back surface of the texture layer 121), to form a pattern layer 130, wherein the shapes of the patterns can be set according to a control function;

and (3) silk-screening a light shielding layer 140 on the surface of the pattern layer 130, which is far away from the texture layer 121, and arranging a light transmitting area in the area, which is just opposite to the pattern, of the light shielding layer 140 to form the PET membrane 100.

For the processed PET film 100, the PET film 100 may be transferred to the transparent plate 220, and the light-shielding layer 140 may be attached to the transparent plate 220.

In the actual manufacturing process, the PET film 100 may be bonded to the transparent plate 220, for example, the light shielding layer 140 is bonded to the transparent plate 220 by the glue 160.

Of course, more layers may be provided between the PET film sheet 100 and the light-transmitting plate 220.

For example, as shown in fig. 3, the display device may further include a PVC (polyvinyl chloride) layer, the light shielding layer 140 is adhered to the PVC layer 150, and the PVC layer 150 is adhered to the light-transmitting plate 220.

In the actual processing process, the PET film 100 may be bonded to the PVC layer 150 by the glue 160, and then the PVC layer 150 may be bonded to the light-transmitting plate 220 by the glue 160.

The additional arrangement of the PVC layer 150 can increase the flatness of the transparent plate 220, so that the light-shielding layer 140 is bonded more stably.

As shown in fig. 4, after the PET film sheet 100 is bonded to the light-transmitting plate 220, the PET layer 110 is directly removed.

The texture layer 121 of the display device thus functions as an outermost layer of the entire display device and also functions to protect the pattern layer 130 of the inner layer.

The following specifically describes embodiments of the present invention from two different implementation perspectives.

First, the light-transmitting plate 220 may be made of a light-transmitting material.

For example, the light-transmitting plate 220 may be made of glass, and the light-transmitting plate 220 may be a glass plate.

The glass plate has good light transmittance, so that the power of the light-emitting device 300 at the inner side can be set to be lower, which is beneficial to reducing the power of the whole electrical equipment and prolonging the service life of the light-emitting device 300.

For this embodiment, the corresponding light emitting device 300 may include various structural forms.

First, the light emitting device 300 includes: light guide plate 310, side light emitting element 320, conductive foam 330 and circuit board 340.

As shown in fig. 5, the light guide plate 310 is located on an inner surface of the light-transmitting plate 220, the inner surface of the light-transmitting plate 220 is a side surface of the light-transmitting plate 220 facing away from the light-shielding layer 140, and the inner surface of the light-transmitting plate 220 is opposite to the top surface of the light guide plate 310.

As shown in fig. 6, the top surface of the light guide plate 310 facing away from the conductive foam 330 may further be provided with light guide textures 312, and the light guide textures 312 may guide the irradiation direction of the light after penetrating through the light guide plate 310.

The light guide plate 310 may be made of acryl (polymethyl methacrylate) material. Thus, the light guide plate 310 has good light transmittance and low hardness, and is not easy to scratch the upper glass plate, and particularly, the glass plate is not abraded in the long-term use process.

The side light emitting elements 320 are mounted on a first side surface of the light guide plate 310, the side light emitting elements 320 are used for emitting light to the light guide plate 310, and the side light emitting elements 320 may be LED light emitting modules.

The side light emitting element 320 is electrically connected to the circuit board 340, and the circuit board 340 is used to supply power to the side light emitting element 320 and control a light emitting state of the side light emitting element 320.

The conductive foam 330 is sandwiched between the light guide plate 310 and the circuit board 340.

It can be understood that the circuit board 340 is provided with touch keys, and when the conductive foam 330 is compressed, the corresponding touch keys can be triggered.

In actual use, each pattern in the pattern layer 130 may be correspondingly provided with the light emitting device 300, when a target pattern is pressed, the light guide plate 310 corresponding to the target pattern moves downward, the conductive foam 330 is compressed, so that the circuit board 340 generates a control command corresponding to the target pattern, and the target pattern is lighted to indicate a user.

As shown in fig. 5 and 6, the pins 321 of the side light emitting device 320 are electrically connected to the circuit board 340, the pins 321 of the side light emitting device 320 can be soldered to the circuit board 340, and the height of the portion of the pins 321 of the side light emitting device 320 between the light guide plate 310 and the circuit board 340 is less than the height of the conductive foam 330, and the conductive foam 330 is spaced apart from the pins 321. The light guide plate 310 is disposed obliquely with respect to the circuit board 340, and a distance from one end of the light guide plate 310 away from the pins 321 to the circuit board 340 is greater than a distance from the other end of the light guide plate 310 to the circuit board 340.

Thus, when the display device is mounted on the whole electrical equipment, the contact area between the light guide plate 310 and the light-transmitting plate 220 is larger, and the light passing rate is higher.

The first side surface of the light guide plate 310 is used for light entering, and the top surface of the light guide plate 310, which faces away from the conductive foam 330, is used for light exiting.

In some embodiments, as shown in fig. 6, the bottom surface (the surface opposite to the light exit surface) of the light guide plate 310 is provided with a reflective layer 311, and the bottom surface of the light guide plate 310 facing the conductive foam 330 is provided with a reflective layer 311. The light thus guided into the light guide plate 310 may be reflected toward the top surface.

In some embodiments, the light guide plate 310 is provided with a light reflecting layer 311 on the surfaces other than the first side surface and the top surface. In this way, more light emitted from the side light emitting elements 320 may be reflected toward the light-transmitting panel 220.

The reflective layer 311 may include reflective paper attached to the light guide plate 310. The reflective paper is low in cost and convenient to assemble.

Second, the light emitting device 300 includes: nixie tubes and ITO touch control films.

The nixie tube is arranged on the inner surface of the light-transmitting plate, and the ITO touch control film is clamped between the light-transmitting plate and the nixie tube.

The light emitting device 300 may further include: the circuit board can also be installed to the below of charactron, and the charactron is connected with the circuit board electricity. The circuit board is used for supplying power to the nixie tube and controlling the light-emitting state of the nixie tube.

Second, the light-transmitting plate 220 may be made of a non-light-transmitting material.

The light-transmitting plate 220 may be made of a non-light-transmitting material, for example, the light-transmitting plate 220 may be made of metal, the light-transmitting plate 220 may be a metal plate, and the metal plate is provided with light-passing holes formed in an array, where an area where the light-passing holes are formed is opposite to the pattern, that is, the light-transmitting plate 220 is provided with the light-passing holes in the area opposite to the pattern.

The plurality of light passing holes may be arranged in a rectangular array, for example, the metal plate is provided with 10 × 10 arrays of light passing holes. The diameter of the light through holes can be smaller than 3mm, and the distance between the light through holes can be smaller than 3 mm. For example, the diameter of the light-passing holes may be 1mm, and the interval between the light-passing holes may be 1.5 mm.

Thus, the light emitting device 300 of this structure may be used for an electric appliance including a metal case.

The specific structure of the light-emitting device 300 can refer to the description of the above embodiments.

Third, the light emitting device 300 includes: a nixie tube 360 and a touch device 350.

The touch device 350 is sandwiched between the transparent plate 220 and the nixie tube 360, and the touch device 350 may be a touch spring 351.

It can be understood that, since the texture layer 121, the pattern layer 130 and the light shielding layer 140 are disposed on one side of the outer surface of the transparent plate 220, the inner surface of the transparent plate 220 has no pattern layer 130 or light shielding layer 140, and the touch spring 351 with low cost can be selected to reduce the production cost.

The light emitting device 300 may further include: the circuit board, the circuit board can also be installed to the below of charactron 360, charactron 360 and circuit board electricity are connected. The circuit board is used for supplying power to the nixie tube 360 and controlling the light-emitting state of the nixie tube 360.
