[0025] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0026] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. For the purpose of simplicity, the description of a particular example below will not necessarily be repeated with each different example. Clearly, however, it is contemplated that where different examples are described, that the features and characteristics of one example can be applied to other examples. Furthermore, many of the components and / or processes described herein are functional entities that can be implemented using either source code or object code, firmware, or microcode, as are known to those skilled in the art, for implementation on one or more computer platforms.

[0027] A panel assembly 100 according to a first embodiment of the present application will be described below with reference to the drawings.

[0028] As Figure 1 and Figure 2As shown, according to the panel assembly 100 of the first aspect of the present application, comprising: a panel body 1 and a display module 2, the panel body 1 is formed with a display area 11, the display area 11 includes a character display area 111 and a non-character display area 112, in the thickness direction of the panel body 1, the thickness of the character display area 111 is less than the thickness of the non-character display area 112, the display module 2 is arranged on the back side of the panel body 1 and is used for emitting light to the character display area 111.

[0029] Wherein, since the thickness of the character display area 111 is less than the thickness of the non-character display area 112, the character display area 111 has good light transmittance compared with the non-character display area 112, therefore, when the display module 2 emits light to the character display area 111, at least part of the light received by the character display area 111 can pass through the character display area 111 to display the corresponding characters on the front wall of the panel body 1, so as to show the numbers and icons on the character display area 111 to the user, and facilitate the user to obtain the running state of the air conditioner.

[0030] Wherein, by directly arranging the character display area 111 on the panel, the film structure for focusing light to form characters in the related art is omitted, the number of parts of the display module 2 can be reduced, such as the two gaps between the film and the cavity and the panel in the related art, and in the present application, there is only one cooperation gap between the display module 2 and the panel body 1, and it can be understood that with the reduction of the cooperation gap, the risk of light leakage and light channeling at the cooperation gap is also reduced. Therefore, by arranging the character display area 111 on the panel, the light leakage and light channeling problems caused by too many cooperation gaps can be reduced, so as to improve the clarity of the displayed characters of the character display area 111. At the same time, only the character display area 111 needs to be thinned on the display area 11, so as to reduce the area of the thinned area on the panel body 1, thereby reducing the injection bulging problem caused by too many thinned areas, so as to improve the production yield of the panel body 1.

[0031] According to the panel assembly 100 of the first aspect of the present application, by arranging the character display area 111 on the panel, the light leakage and light channeling problems caused by too many cooperation gaps can be reduced, so as to improve the clarity of the displayed characters of the character display area 111, and at the same time, the area of the thinned area on the panel body 1 can be reduced, thereby reducing the injection bulging problem caused by too many thinned areas, so as to improve the production yield of the panel body 1.

[0032] According to some embodiments of the present application, the back of the display area 11 is formed with a plurality of character line grooves 1111 open to the display module 2, the display module 2 is used to emit light to the character line grooves 1111, and the plurality of character line grooves 1111 jointly constitute a character display area 111. That is, the display module 2 emits light into the character line grooves 1111, and the light can be focused well through the character line grooves 1111, so that the light forms a specified character shape and is finally displayed on the front wall of the panel assembly 100, so as to improve the clarity of the displayed characters on the front wall of the panel body 1. Wherein, the characters of specified shape can be formed by a single character line groove 1111 or a plurality of character line grooves 1111 in cooperation, which is not specifically limited here.

[0033] In some embodiments, the front walls of the character display area 111 and the non-character display area 112 are coplanar. Thus, the light passing through the character line grooves 1111 can be more intuitively limited on the front wall of the panel body 1, so as to ensure that the user can accurately and directly obtain the displayed character information, and at the same time, the consistency of the front wall of the panel body 1 can be better ensured, and the aesthetic degree of the panel body 1 is improved.

[0034] According to some embodiments of the present application, the plurality of character line grooves 1111 at least includes a mode line groove and a temperature line groove. Therefore, the display module 2 can form a mode icon on the panel body 1 by emitting light into the corresponding mode line groove, and the display module 2 can also form a temperature number on the panel body 1 by emitting light into the corresponding temperature line groove, so that the user can clearly and accurately know the current running mode and temperature of the air conditioner through the panel body 1.

[0035] Specifically, the mode line groove can include icons of cooling, heating, dehumidifying, fresh air and the like, so that by controlling the display module 2 to emit light into the corresponding mode line groove, the icon of the corresponding mode can be displayed on the panel body 1, so as to facilitate the user to clearly and accurately judge the running mode of the current air conditioner. The temperature line groove can include a plurality of digital characters, such as a plurality of "8" characters, and each digital character can display any one of 0 to 9 by controlling the display module 2 to emit light into the corresponding temperature line groove, so that the current temperature can be displayed through the cooperation of the plurality of digital characters, so as to facilitate the user to clearly and accurately know the set temperature of the current air conditioner and the like.

[0036] According to some embodiments of the present application, in the thickness direction of the panel body 1, the thickness range t of the character display area 111 satisfies: 0 < t ≤ 0.8mm. Among them, it can be understood that the thickness of the character display area 111 is inversely proportional to its light transmittance, that is, the thicker the thickness of the character display area 111, the worse the light transmittance of the character display area 111, and the thinner the thickness of the character display area 111, the better the light transmittance of the character display area 111. Therefore, by controlling the thickness of the character display area 111 within the range of not more than 0.8mm, the character display area 111 has a relatively thin thickness size, so as to ensure the light transmittance of the character display area 111, thereby improving the clarity of the character display area 111 displaying the air conditioner information. For example, the thickness of the character display area 111 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, etc.

[0037] According to some embodiments of the present application, the back of the non-character display area 112 is provided with a light shielding material layer. Among them, it can be understood that the display module 2 is located at the back side of the display area 11, the display module 2 emits light forward, the light shielding material layer is arranged between the display area 11 and the display module 2, and the light shielding material layer can absorb light. The light emitted by the display module 2 can be prevented from shining on the back of the non-character display area 112, that is, the light emission of the non-character display area 112 can be avoided through the light shielding material layer, so as to ensure that only the character display area 111 emits light, thereby avoiding the display of the character display area 111 being blurred due to the light emission of the non-character display area 112, and improving the clarity of the display area 11 displaying the running information of the air conditioner.

[0038] In some embodiments, the character display area 111 is composed of a plurality of character line grooves 1111, so that during the coating process of the light shielding material layer, the light shielding ink can be prevented from entering the character line groove 1111, and the coating difficulty of the light shielding material layer can be reduced. Among them, the light shielding material layer can be fixed on the panel body 1 by pad printing, silk printing, hot stamping, pasting and the like, which is not limited here.

[0039] According to some embodiments of the present application, the back of the panel body 1 is formed with a recessed positioning groove 12, and the display area 11 is formed on the inner bottom wall of the positioning groove 12 facing the display module 2. Therefore, during the assembly of the display module 2, the display module 2 can be installed by aligning the positioning groove 12, such as inserting the front end of the display module 2 into the positioning groove 12, so as to reduce the positioning difficulty during the installation of the display module 2, thereby improving the installation efficiency of the display module 2 while ensuring the installation position accuracy of the display module 2. In addition, the positioning groove 12 facilitates the positioning of the coating position of the light shielding material layer on the non-character display area 112, thereby reducing the difficulty of coating the light shielding material layer on the non-character display area 112, and improving the coating efficiency of the light shielding material layer.

[0040] According to some embodiments of the present application, the display module 2 comprises a display panel 21 and a reflection cavity 22, the reflection cavity 22 is arranged between the display panel 21 and the panel body 1, the side of the display panel 21 facing the reflection cavity 22 is provided with a light emitting part, the reflection cavity 22 is formed with a light cavity 221 opposite to the character display area 111, the light emitting part is located in the light cavity 221, and the wall surface of the reflection cavity 22 away from the display panel 21 abuts against the back surface of the display area 11. It should be noted that the light emitted by the light emitting part is separated into multiple independent character shapes by the multiple light cavities 221, so that the light emitted by the light emitting part can be limited to the corresponding character shape by a single light cavity 221 or multiple light cavities 221, that is, the light emitted by the light emitting part first enters the light cavity 221, and then enters the corresponding area of the character display area 111 after being focused by the light cavity 221, and since the reflection cavity 22 abuts against the back surface of the display area 11, the light focused by the reflection cavity 22 can be prevented from leaking and light channeling through the gap between the reflection cavity 22 and the panel body 1. Therefore, the light emitted by the light emitting part can be well focused by the reflection cavity 22, and the light emitted by the display module 2 can be well prevented from leaking or light channeling by the abutting cooperation of the reflection cavity 22 and the panel body 1, so that the clarity of the character display area 111 in displaying characters can be improved.

[0041] According to some embodiments of the present application, the back surface of the panel body 1 is formed with a recessed positioning groove 12, the display area 11 is formed on the inner bottom wall of the positioning groove 12 facing the display module 2, and one end of the reflection cavity 22 away from the display panel 21 is located in the positioning groove 12. Therefore, in the assembly of the display module 2, after the reflection cavity 22 is installed on the display panel 21, the front end of the reflection cavity 22 can be inserted into the positioning groove 12 in alignment, so that the positioning difficulty in the installation of the display module 2 can be reduced, and the installation efficiency of the display module 2 can be improved while ensuring the installation position accuracy of the display module 2.

[0042] According to some embodiments of the present application, in the direction from the display area 11 to the display panel 21, the inner peripheral surface of the positioning groove 12 extends obliquely towards the direction away from the center of the display area 11. The inner peripheral surface of the positioning groove 12 here refers to the inner wall surface of the positioning groove 12 surrounding the outer peripheral side of the reflection cavity 22 in the direction perpendicular to the front-rear direction. Therefore, in the process of inserting the front end of the reflection cavity 22 into the positioning groove 12, the inner peripheral surface of the positioning groove 12 can provide a good guiding effect for the reflection cavity 22 to correct the positional deviation in the installation process of the reflection cavity 22, thereby facilitating the reduction of the installation difficulty of the display module 2.
