Description
本發明涉及一種顯示設備,尤其是一種避免異物進入顯示設備內部的顯示設備。The present invention relates to a display device, in particular to a display device which prevents foreign matter from entering the interior of the display device.
顯示設備已經成為一種廣泛應用於我們日常生活各個領域的簡單、便捷的人機交互媒介。然而,異物(如灰塵)進入顯示設備的內部空間,會影響顯示設備的性能,例如影響光學品質,或使內部元件受損導致使用壽命降低。Display devices have become a simple and convenient human-computer interaction medium widely used in various fields of our daily life. However, foreign matter (such as dust) entering the internal space of the display device will affect the performance of the display device, such as affecting the optical quality, or damaging the internal components and reducing the service life.
為了阻止異物(如灰塵)進入顯示設備的內部空間,可以設置膠帶或泡棉於外框與面板之間、面板與膠框之間。現有的方式是將泡棉或膠帶切割成口字型(如圖1所示)並組裝到顯示設備中,然而,這種設計方式存在嚴重的材料浪費問題,尤其是對於尺寸越大的顯示設備,泡棉的浪費也越嚴重,導致產品生產成本增加。若將泡棉或膠帶切割成矩形再拼接成口字型(如圖2所示),則拼接處間的縫隙會導致無法起到防塵密封的作用。In order to prevent foreign matter (such as dust) from entering the internal space of the display device, tape or foam can be placed between the outer frame and the panel, and between the panel and the tape frame. The existing method is to cut the foam or tape into a square shape (as shown in Figure 1) and assemble it into the display device. However, this design method has a serious problem of material waste, especially for larger display devices, the foam waste is more serious, resulting in increased product production costs. If the foam or tape is cut into rectangles and then spliced into a square shape (as shown in Figure 2), the gap between the splicing will result in the inability to play the role of dustproof sealing.
有鑒於上述問題,依據一實施例,顯示設備包含面板模塊、膠框、防塵部件及外框。膠框承載面板模塊。防塵部件包含黏性層與泡棉層。泡棉層抵頂貼面板模塊,包含彎折的泡棉層通道。黏性層黏貼泡棉層,包含彎折的黏性層通道。外框抵壓防塵部件而限位面板模塊,並使泡棉層的部份覆蓋黏性層通道、黏性層的部份覆蓋泡棉層通道。In view of the above problems, according to one embodiment, a display device includes a panel module, a plastic frame, a dustproof component and an outer frame. The plastic frame carries the panel module. The dustproof component includes an adhesive layer and a foam layer. The foam layer is pressed against the panel module, including a bent foam layer channel. The adhesive layer is attached to the foam layer, including a bent adhesive layer channel.

於一些實施例中,黏性層通道與泡棉層通道的寬度介於0.5 mm至5 mm之間。In some embodiments, the width of the viscous layer channel and the foam layer channel is between 0.5 mm and 5 mm.
於一些實施例中,黏性層通道包含第一黏性層開口與第二黏性層開口,第一黏性層開口位於黏性層的外側邊,第二黏性層開口位於黏性層的內側邊,泡棉層通道包含第一泡棉層開口與第二泡棉層開口,第一泡棉層開口位於泡棉層的外側邊,第二泡棉層開口連位於泡棉層的內側邊。In some embodiments, the adhesive layer channel includes a first adhesive layer opening and a second adhesive layer opening, the first adhesive layer opening is located at the outer edge of the adhesive layer, and the second adhesive layer opening is located at the inner edge of the adhesive layer; the foam layer channel includes a first foam layer opening and a second foam layer opening, the first foam layer opening is located at the outer edge of the foam layer, and the second foam layer opening is located at the inner edge of the foam layer.
於一些實施例中,黏性層包含第一黏性層與第二黏性層,第一黏性層包含第一黏性層凹部,第二黏性層包含第二黏性層凸部,第二黏性層凸部位於第一黏性層凹部內並於第一黏性層凹部與第二黏性層凸部之間形成黏性層通道。In some embodiments, the adhesive layer includes a first adhesive layer and a second adhesive layer, the first adhesive layer includes a first adhesive layer concave portion, the second adhesive layer includes a second adhesive layer convex portion, the second adhesive layer convex portion is in the first adhesive layer concave portion and forms an adhesive layer channel between the first adhesive layer concave portion and the second adhesive layer convex portion.
於一些實施例中,泡棉層包含第一泡棉層與第二泡棉層,第一泡棉層包含第一泡棉層凹部,第二泡棉層包含第二泡棉層凸部,第二泡棉層凸部位於第一泡棉層凹部內並於第一泡棉層凹部與第二泡棉層凸部之間形成泡棉層通道。In some embodiments, the foam layer includes a first foam layer and a second foam layer, the first foam layer includes a first foam layer concave portion, the second foam layer includes a second foam layer convex portion, the second foam layer convex portion is in the first foam layer concave portion and forms a foam layer channel between the first foam layer concave portion and the second foam layer convex portion.
於一些實施例中,黏性層包含第一黏性層與第二黏性層,第一黏性層的一端為第一黏性層凹部,第二黏性層的一端位於第一黏性層凹部而形成黏性層通道。In some embodiments, the adhesive layer includes a first adhesive layer and a second adhesive layer, one end of the first adhesive layer is the first adhesive layer concave portion, and one end of the second adhesive layer is located in the first adhesive layer concave portion to form an adhesive layer channel.
於一些實施例中,泡棉層包含第一泡棉層與第二泡棉層,第一泡棉層的一端為第一泡棉層凹部,第二泡棉層的一端位於第一泡棉層凹部而形成泡棉層通道。In some embodiments, the foam layer includes a first foam layer and a second foam layer, one end of the first foam layer is the first foam layer concave portion, and one end of the second foam layer is located in the first foam layer concave portion to form a foam layer channel.
於一些實施例中,防塵部件更包含一黏著層,黏著層黏貼泡棉層,黏著層包含彎折的一黏著層通道,於外框抵壓防塵部件,黏著層的一部份覆蓋泡棉層通道、泡棉層的一部份覆蓋黏著層通道。In some embodiments, the dustproof component further includes an adhesive layer, the adhesive layer is adhered to the foam layer, the adhesive layer includes a bent adhesive layer channel, the dustproof component is pressed against the outer frame, a portion of the adhesive layer covers the foam layer channel, and a portion of the foam layer covers the adhesive layer channel.
綜合上述,在任一些實施例中當異物(如灰塵)隨著空氣進入泡棉層通道時,異物會掉落於黏性層,並黏附於黏性層上。此外,彎折處作為緩衝空間能延長空氣在泡棉層通道中流動的時間而增加異物掉落於黏性層的比率,並且,異物容易被泡棉層彎折處的內壁面的阻擋而掉落於黏性層,而能有效地減少異物進入顯示設備內部,達到避免異物影響顯示設備性能的效果。而當異物隨著空氣進入黏性層通道時,由於黏性層通道的內壁面具有黏性,且異物容易受黏性層通道彎折處的內壁面阻擋而有效地黏附於黏性層通道的內壁面,而能有效地減少異物進入顯示設備內部,達到避免異物影響顯示設備性能的效果。另外,在一些實施例中,黏性層通道與泡棉層通道會連通顯示設備的內部空間與外部空間。如此,可以使顯示設備的內外壓力平衡,避免因重工(rework)或維修,外框脫離面板模塊或面板模塊脫離膠框,所導致壓力差對顯示設備產生的結構性破壞。又在一些實施例中,當異物(如灰塵)隨著空氣進入泡棉層通道時,異物會掉落於黏著層並黏附於黏著層,並且,異物容易受黏著層通道彎折處的內壁面阻擋而黏附於黏著層通道的內壁面,故能有效地減少異物進入顯示設備內部。In summary, in any of the embodiments, when foreign matter (such as dust) enters the foam layer channel along with the air, the foreign matter will fall on the viscous layer and adhere to the viscous layer. In addition, the bend, as a buffer space, can extend the time for air to flow in the foam layer channel and increase the rate of foreign matter falling on the viscous layer. Moreover, foreign matter is easily blocked by the inner wall surface of the bend of the foam layer and falls on the viscous layer, which can effectively reduce the entry of foreign matter into the display device, thereby achieving the effect of preventing foreign matter from affecting the performance of the display device. When foreign matter enters the viscous layer channel along with the air, the inner wall surface of the viscous layer channel is viscous, and the foreign matter is easily blocked by the inner wall surface of the viscous layer channel bend and effectively adheres to the inner wall surface of the viscous layer channel, which can effectively reduce the entry of foreign matter into the display device, thereby achieving the effect of preventing foreign matter from affecting the performance of the display device. In addition, in some embodiments, the viscous layer channel and the foam layer channel will connect the internal space and the external space of the display device. In this way, the internal and external pressures of the display device can be balanced, avoiding structural damage to the display device caused by the pressure difference caused by the outer frame being separated from the panel module or the panel module being separated from the plastic frame due to rework or maintenance. In some embodiments, when foreign matter (such as dust) enters the foam layer channel along with the air, the foreign matter will fall onto the adhesive layer and adhere to the adhesive layer. Moreover, the foreign matter is easily blocked by the inner wall surface of the adhesive layer channel bend and adheres to the inner wall surface of the adhesive layer channel, thereby effectively reducing the entry of foreign matter into the interior of the display device.

於一些實施例,黏性層32可包含第一黏性層321與第二黏性層322。在此,第一黏性層321與第二黏性層322可為長條狀,且第一黏性層321與第二黏性層322依序沿著外框40的側邊黏貼。第一黏性層321與第二黏性層322的拼接處為黏性層通道320,換言之,黏性層通道320位於第一黏性層321與第二黏性層322之間。In some embodiments, the
請繼續參照圖5,黏性層通道320與泡棉層通道310投影在水平面上的正投影面不會重疊,意即,黏性層通道320與泡棉層通道310於正投影面相互錯位。因此,於一些實施例,如圖6A,於外框40抵壓防塵部件30(包含黏性層32與泡棉層31)而限位面板模塊10時,泡棉層31的一部份會覆蓋黏性層通道320,且黏性層32的一部份會覆蓋泡棉層通道310。並且,於一些實施例,如圖6B所示,當面板模塊10抵壓防塵部件30時,泡棉層31的一部份會覆蓋黏性層通道320,且黏性層32的一部份會覆蓋泡棉層通道310。Please continue to refer to FIG. 5 . The orthographic projection plane of the
進一步地,於一些實施態樣,當外框40抵押泡棉層31與黏性層32時,或面板模塊10抵壓防塵部件30時,泡棉層31受壓而會使與黏性層通道320相重疊部份陷入黏性層通道320而填補部份的黏性層通道320,此時,黏性層32亦受壓而使與泡棉層通道310相重疊的部份陷入泡棉層通道310而填補部份的泡棉層通道310。Furthermore, in some embodiments, when the
如此,如圖4、圖6A及圖6B所示,當異物(如灰塵)隨著空氣進入泡棉層通道310時,異物會掉落於黏性層32,並黏附於黏性層32上。此外,彎折處作為緩衝空間能延長空氣在泡棉層通道310中流動的時間而增加異物掉落於黏性層32的比率,並且,異物容易被泡棉層31彎折處的內壁面31a的阻擋而掉落於黏性層32,而能有效地減少異物進入顯示設備1內部(例如圖4的中空區60)。而當異物隨著空氣進入黏性層通道320時,由於黏性層通道320的內壁面32a具有黏性,且異物容易受黏性層通道320彎折處的內壁面32a阻擋而有效地黏附於黏性層通道320的內壁面32a,而能有效地減少異物進入顯示設備1內部(例如圖4的中空區60)。Thus, as shown in FIG. 4 , FIG. 6A and FIG. 6B , when foreign matter (such as dust) enters the
如此,當空氣通過面板模塊10與外框40之間的防塵部件30,及通過面板模塊10與膠框20防塵部件30之間的防塵部件30時,能有效地降低異物進入面板模塊10、膠框20與外框40之間的空間S或中空區60,從而避免異物影響顯示設備1的性能。In this way, when air passes through the

請參圖9,圖9為一些實施例的防塵部件的組裝流程示意圖。在此,圖9省略膠框20與面板模塊10。在一些實施例中,先裁切使第一黏性層321具有第一黏性層凹部321a,並使第二黏性層322具有第二黏性層凸部322a。再將第一黏性層321與第二黏性層322依序沿著面板模塊10的側邊黏貼成口字型,或沿著膠框20支撐部22的上表面22a黏貼成口字型。或是先僅裁切使第一黏性層321具有第一黏性層凹部321a,且不裁切第二黏性層322。再將第一黏性層321與第二黏性層322(不具有第二黏性層凸部322a)依序沿著面板模塊10的側邊黏貼成口字型,或沿著膠框20支撐部22的上表面22a黏貼成口字型。最後,再將經過裁切的泡棉層31(詳見圖7A)黏貼於經過裁切的黏性層32。Please refer to FIG. 9, which is a schematic diagram of the assembly process of the dustproof component of some embodiments. Here, FIG. 9 omits the
請參照圖10,圖10為一些實施例的圖4中標示B的位置的放大示意圖(二)。在一些實施例中,防塵部件30可更包含黏著層33,且黏著層33黏貼泡棉層31。黏著層33包含彎折的黏著層通道330,於外框40抵壓防塵部件30時,黏著層33的一部份覆蓋泡棉層通道310、泡棉層31的一部份覆蓋黏著層通道330。換言之,泡棉層通道310疊合於黏著層33不具有黏著層通道330的部份,而黏著層通道330疊合於泡棉層31不具有泡棉層通道310的部份。此外,黏著層通道330的內壁面33a具有黏性,異物容易受黏著層通道330彎折處的內壁面33a阻擋而有效地黏附於黏著層通道330的內壁面33a。Please refer to FIG. 10 , which is an enlarged schematic diagram (II) of the position marked B in FIG. 4 of some embodiments. In some embodiments, the
在此,黏著層33例如為雙面皆具有黏性的膠帶,而黏著層通道330為不具膠帶的部份。黏著層通道330的彎折處可以為但不限於階梯型或弧形等形狀。此外,此實施例的防塵部件30可以但不限於設置於面板模塊10與外框40之間,亦可設置於面板模塊10與膠框20(如圖4)之間。Here, the
綜合上述,在任一些實施例中,當異物(如灰塵)隨著空氣進入泡棉層通道310時,異物會掉落於黏性層32,並黏附於黏性層32上。此外,彎折處作為緩衝空間能延長空氣在泡棉層通道310中流動的時間而增加異物掉落於黏性層32的比率,並且,異物容易被泡棉層31彎折處的內壁面31a的阻擋而掉落於黏性層32,而能有效地減少異物進入顯示設備1內部,達到避免異物影響顯示設備1性能的效果。而當異物隨著空氣進入黏性層通道320時,由於黏性層通道320的內壁面32a具有黏性,且異物容易受黏性層通道320彎折處的內壁面32a阻擋而有效地黏附於黏性層通道320的內壁面32a,而能有效地減少異物進入顯示設備1內部,達到避免異物影響顯示設備1性能的效果。另外,在一些實施例中,黏性層通道320與泡棉層通道310會連通顯示設備1的內部空間與外部空間。如此,可以使顯示設備1的內外壓力平衡,避免因重工(rework)或維修時,外框40脫離面板模塊10,或面板模塊10脫離膠框20所導致的壓力差對顯示設備1產生的結構性破壞。又在一些實施例中,當異物(如灰塵)隨著空氣進入泡棉層通道310時,異物會掉落於黏著層33並黏附於黏著層33,並且,異物容易受黏著層通道330彎折處的內壁面33a阻擋而黏附於黏著層通道330的內壁面33a,故能有效地減少異物進入顯示設備1內部。In summary, in any of the embodiments, when foreign matter (such as dust) enters the
