[0078] With reference to [Fig. 1] to 6, the present invention proposes an ultra-thin screen 10 with a backlight source, and the ultra-thin screen 10 can be used in automobiles, household appliances, consumer electronics and other fields. In one embodiment, the ultra-thin screen 10 is particularly designed for use in the automotive field as an in-car display device, the display size of which can be between 15.24 and 35.56 cm; it is understood that its specific size is not limited and can be adjusted according to actual needs.

[0079] The ultra-thin screen 10 includes a housing 11 for accommodating various components. In one embodiment, the ultra-thin screen 10 further includes a printed circuit board 140, a backlight assembly 13, a display module 14 and a glass plate 15 housed in the housing 11; the printed circuit board 140, the backlight assembly 13, the display module 14 and the glass plate 15 are housed sequentially in the housing space 11; wherein the printed circuit board 140 is arranged closer to the base plate 110 than to the glass plate 15.

[0080] In one embodiment, the housing 11 comprises a base plate 110 and a plurality of end-to-end side plates 120. The plurality of side plates 120 are connected to the base plate 110, thus forming a housing space 11a provided with an opening 11b. It is understood that at least a portion of the base plate 110 and the side plates 120 are formed as a single piece, or they may be molded separately and then attached together. The printed circuit board 140, the backlight assembly 13, the display module 14, and the glass plate 15 are sequentially housed in the housing space 11a, and the glass plate 15 covers the opening 11b.

[0081] In a specific embodiment, the base plate 110 is rectangular in shape, and the side plates 120 comprise first side plates 121, second side plates 122, third side plates 123 and fourth side plates 124, which are opposite; the first side plates 121 and the third side plates 123 are arranged opposite each other, the second side plates 122 and the fourth side plates 124 are arranged opposite each other; the first side plates 121, the second side plates 122, the third side plates 123 and the fourth side plates 124 are connected end to end, and are connected to the base plate 110 in four different orientations of the base plate 110.The base plate 110, together with the first side plate 121, the second side plate 122, the third side plate 123, and the fourth side plate 124, form a housing space lia. This housing space lia has an opening 11b. It is understood that the base plate 110 is rectangular in shape, meaning that its outer contour is substantially rectangular, and it is not necessary for it to have a standard rectangular shape. The corners may be chamfered or rounded.

[0082] In one embodiment, the base plate 110 comprises a plate body portion 111 and a cover body portion 112. The plate body portion 111 is provided with a through hole 113. The cover body portion 112 closes the through hole 113 and is removably connected and fixed to the plate body portion 111. In one embodiment, the plate body portion 111 is substantially at the same level as a surface of the cover body portion 112 opposite the backlight assembly 13.

[0083] In one embodiment, the dimensions of the through hole 113 are greater than or equal to the dimensions of the printed circuit board 140 in order to allow the printed circuit board 140 to be mounted in the housing space through the through hole 113, and to allow a user to open the cover body portion 112 for maintenance of the printed circuit board 140. In one embodiment, the printed circuit board 140 is glued and fixed to the backlight assembly 13 through the through hole 113, thereby reducing the thickness of the product.

[0084] In one embodiment, the printed circuit board 140 is fixed by fitting to the surface of the backlight assembly 13 opposite the opening 11b.

[0085] In one embodiment, the printed circuit board 140 can be arranged in the immediate vicinity of the surface of the backlight assembly 13 opposite the opening 11b, instead of being fixed by fit to the surface of the backlight assembly 13 opposite the opening 11b.

[0086] In one embodiment, the printed circuit board 140 comprises a board 1401 and a plurality of electronic components 1402 arranged on the board 1401. The plurality of electronic components 1402 are arranged on a surface of the board 1401 opposite the backlight assembly 13. Part of the electronic components 1402 is housed in the housing space 11a, and part of the electronic components 1402 extends through the cover body portion 112 to be exposed outside the housing 11. In this way, the taller electronic components 1402 can be exposed outside the housing 11, thus avoiding the increase in product thickness caused by electronic components entirely contained within the housing space 11a. The taller electronic components 1402 may be terminal blocks.

[0087] In one embodiment, the plate body portion 111 is provided with a first recessed area 111a in three different orientations of the base plate 110, i.e., at least one first recessed area 111a is provided in three different orientations of the base plate 110. A second recessed area 111b (namely a groove) is provided in a different orientation from that in which the first recessed area 111a is provided, the first recessed area 111a having a different function from that of the second recessed area 111b (described below). The second recessed zone 111b is located in a different orientation from the base plate 110 compared to the first recessed zone 11a. The second recessed zone 111b is located near the first side plate 121, and the first recessed zone 111a is located near the second side plate 122, the third side plate 123, and the fourth side plate 124. The second recessed zone 111b extends to the edge of the base plate 110 in its orientation, that is, to the first side plate 121, to facilitate wiring. Furthermore, the second recessed zone 111b extends to the through hole 113 to facilitate electrical connection.

[0088] In one embodiment, the second recessed zone 111b has at least a first depth and a second depth.

[0089] The backlight assembly 13 comprises a first surface 13a and a second surface 13b, which are opposite each other; the first surface 13a is opposite the display module 14, and the second surface 13b is near the display module 14; the first surface 13a of the backlight assembly 13 is bonded and fixed to the base plate 110. It is understood that, while the first surface 13a is bonded to the base plate 110, it is not necessary for the first surface 13a to be fully fitted against the base plate 110, as long as it is ensured that the first surface 13a is at least partially fitted against the base plate 110 to achieve the bonding. More specifically, the surface of the backlight assembly 13 opposite the opening 11b is fixed by a fit to the plate body portion 111.

[0090] In one embodiment, the bonding between the first surface 13a and the base plate 110 is achieved using a first type of adhesive (not shown) and a second type of adhesive (not shown); more specifically, the bonding between the first surface 13a and the plate body portion 111 is achieved using the first type of adhesive and the second type of adhesive. The first type of adhesive is an adhesive having both bonding and support functions, such as 3M Very High Bond (VHB) tape or other commercially available adhesives. The second type of adhesive primarily serves the bonding function, such as a commercially available structural adhesive. During application, it has the advantage of being conformable due to its liquid state and can then be cured to achieve the bond.During bonding, the support effect of the first type of adhesive can cause the first surface 13a to fit against the base plate 110 while ensuring that there is a small gap between the two, in order to facilitate the formation of a space between the two to accommodate other components, such as the printed circuit board 140. In one embodiment, the gap between the base plate 110 (the area not provided by the first recessed area 11a and the second. recessed area 111b) and the backlight assembly 13 is 0.3 to 0.8 mm, which can further be 0.4 to 0.8 mm, 0.5 to 0.8 mm, 0.5 to 0.6 mm.

[0091] In one embodiment, the first type of adhesive comprises a backing sheet and an adhesive layer disposed on two opposite surfaces of the backing sheet; the second type of adhesive is a sand-cured adhesive in the liquid state, preferably a structural adhesive.

[0092] In one embodiment, the first type of adhesive is arranged in at least three different orientations of the base plate 110; the second type of adhesive is arranged between the first type of adhesive. More specifically, the first type of adhesive is arranged in the first recessed area 11a, and the first recessed area 111a becomes a first adhesion zone; the first type of adhesive is arranged in the first recessed area 111a located in three different orientations. The arrangement of the first recessed area 111a facilitates the positioning of the adhesive for the first type of adhesive, thus avoiding random bonding that tilts the backlight assembly 13 relative to the base plate 110 and affects the lighting effect.In one embodiment, the first type of adhesive is in the form of an adhesive strip, and the first type of adhesive inside each first recessed area 111a may be one or more strips, and the first type of adhesive covers at least part of the first recessed area 111a.

[0093] In one embodiment, the thickness of the first type of adhesive is 0.3 to 1 mm; after bonding, the thickness of the first type of adhesive is greater than the thickness of the second type of adhesive; and the distance between the base plate 110 and the backlight assembly 13 is 0.3 to 0.8 mm, i.e. the second type of adhesive has a thickness after hardening of 0.3 to 0.8 mm, which can further be 0.4 to 0.8 mm, 0.5 to 0.8 mm, 0.5 to 0.6 mm.

[0094] The plate body portion 111 is provided with an area having the second type of adhesive, which forms a second adhesion zone. In one embodiment, the second adhesion zones are formed between the first adjacent adhesion zones.

[0095] In one embodiment, the second recessed area 111b is internally provided with an FPC 16, and the FPC 16 is electrically connected to the printed circuit board 140, the backlight assembly 13, and the display module 14; a portion of a side face of one or more of the display module 14 and the backlight assembly 13 is attached, removably (e.g., by snap-fit) or not (e.g., by adhesive), to the side plates 120, and another portion forms a cable passage S with the side plates 120; the cable passage corresponds in position to the second recessed area 111b, and both are located in the same orientation of the base plate 110, i.e. that the cable passage S is located inside the first side plate 121.

[0096] A portion of a side face (a face in the thickness direction) of one or more of the display module 14 and the backlight assembly 13 is glued to the side plates 120. In a specific embodiment, a portion of the side face of the display module 14 is glued to the side plates 120, a portion of the side face of the backlight assembly 13 is glued to the side plates 120, thus, the gluing of their side face portions to the side plates 120 allows the fixed connection of the two to the housing 11, in addition, another portion of the side face is not glued to the side plates 120, thus allowing the formation of a cable passage for the wiring between the two and the side plates 120.

[0097] In one embodiment, the sides of the glass plate 15 are fully bonded to the side plates 120, in order to ensure both fixing and sealing. In some embodiments, the surface of the glass plate 15 may be covered with a protective film 19, such as an explosion-proof film, a privacy film, etc.

[0098] In one embodiment, the backlighting assembly 13 comprises a light bar 132, as well as a reflector 131, a light-conducting plate 133 and a plurality of optical films, which are sequentially layered; the optical films are brightness-enhancing films and / or diffusing films; The light bar 132 is arranged on the side of the light-conducting plate 133 near the cable passage, in order to facilitate the passage of the FPC 16 connected to the light bar 132 through the cable passage and its entry into the second recessed area 111b.

[0099] In one embodiment, the backlight assembly 13 comprises a light bar 132, a reflector 131, a light-conducting plate 133, a lower diffusing film 134, an upper brightness-enhancing film 135, and a double brightness-enhancing (DBEF) film 136, which are layered; the light bar 132 is arranged on one side of the light-conducting plate 133, and a surface of the reflector 131 opposite the light-conducting plate 133 is the first surface 13a; the display module 14 is an LCD module, and the glass plate 15 is fully fitted against the surface of the LCD module. In this way, while optimizing the number of components, the product's function is ensured and the product's thickness is reduced.

[0100] In one embodiment, the distance between the LCD module and the DBEF 136 is 0.5 to 1 mm. The distance can also be 0.5 to 0.8 mm, 0.5 to 0.7 mm, or 0.5 to 0.6 mm.

[0101] In one embodiment, the distance between a surface of the glass plate 15 opposite the display module 14 and a surface of the plate body part 111 opposite the backlight assembly 13 is less than or equal to 15 mm. In addition, the distance between the surface of the glass plate 15 opposite the display module 14 and the surface of the plate body part 111 opposite the backlight assembly 13 is less than or equal to 13 mm.

[0102] In one embodiment, the height of the side plate 120 may exceed the glass plate 15 in order to protect the glass plate 15.

[0103] In one embodiment, the ultra-thin screen 10 is an embedded screen with a thickness less than or equal to 15 mm.

[0104] In one embodiment, the size of said embedded screen is from 15.24 to 35.56 cm.

[0105] In one embodiment, the ultra-thin screen 10 further comprises a base 18 and a connecting element 17, and the base 18 is connected to the housing 11 via the connecting element 17. In one embodiment, the connecting element 17 is connected to the housing 11 by screws. The position of the connecting element 17 screwed to the housing 11 corresponds to the position of the first type of adhesive.

[0106] In one embodiment, the base plate 110 is provided with mounting holes 111c in the first recessed area 111a in two opposite directions; the first type of adhesive covers the mounting holes 111c. When fasteners, such as screws, are installed in the mounting holes 111e, iron filings are likely to fall out after a long period and affect the operation of the product, for example by affecting the normal operation of the printed circuit board 140. This problem can be avoided by covering the mounting holes 111c with the first type of adhesive, and the reuse of the first type of adhesive is also achieved.

[0107] In one embodiment, during the assembly of the ultra-thin screen 10, after the FPC 16 is mounted, the reflector 131 can be glued to the base plate 110. Then, the light-conducting plate 133, the upper / lower diffusing film, the upper / lower brightness-enhancing film, and the DBEF 136 are laminated. After the light bar 132 is mounted, an adhesive is applied so that certain sides of the light bar 132, as well as the laminated light-conducting plate 133, upper / lower diffusing film, upper / lower brightness-enhancing film, and DBEF 136, are glued to the housing 11. Furthermore, the cable passage for the FPC 16 is formed between an unglued area on the side of the light bar 132 and the side plates 120. The module display 14 is positioned at a certain distance from the backlight assembly 13 and fixed to the side plates 120 by adhesive.The FPC16 on the light bar 132 can pass through the cable passage and enter the second recessed area 111b (it is also possible that the FPC 16 passes through the cable passage from the second recessed area 111b to be connected to the light bar 132), and the FPC16 protrudes from the cable passage to be connected to the display module 14 (the module. The display module 14 and the FPC16 can also remain permanently connected at all times. The FPC16 connected to the light bar 132 and the FPC16 connected to the display module 14 are located in the second recessed area 111b, which has the first and second depths, respectively. Then, the glass plate 15 is fully fitted against the display module 14, and all sides of the glass plate 15 are bonded to the side plates 120. Finally, the cover body part 112 is removed, the printed circuit board 140 is bonded to the reflector 131, and the cover body part 112 is replaced.

[0108] In one embodiment, the printed circuit board 140 can be mounted before the reflector 131 is mounted.
