Description

顯示裝置Display device

本發明是有關於一種顯示裝置，且特別是有關於一種在膠框中形成磁性材料的顯示裝置。The present invention relates to a display device, and more particularly to a display device in which a magnetic material is formed in a plastic frame.

隨著科技的發展，顯示裝置被廣泛應用在許多電子產品上，如手機、平板電腦、手錶等。為了提高顯示質量，大尺寸、高解析度、高亮度的顯示裝置應運而生。With the development of technology, display devices are widely used in many electronic products, such as mobile phones, tablet computers, watches and so on. In order to improve display quality, large-size, high-resolution, and high-brightness display devices have emerged.

圖1A是現有顯示裝置的結構示意圖，圖1B是圖1A沿A-A’的剖面示意圖。如圖1A、圖1B所示，顯示裝置100包括背光模組101，與背光模組101相鄰設置有膠框102，背光模組101以及膠框102設置在殼體106上。舉例而言，背光模組101可包含光源、導光板、光學膜片等，殼體106可以是金屬材料或高分子材料，可用於承載背光模組101以及膠框102，也可以作為顯示裝置100的外觀殼體。口字形膠帶103形成於背光模組101及膠框102上，顯示面板104的上下表面上均形成偏光片105，顯示面板104及偏光片105疊設於背光模組101上，並通過口字形膠帶103與背光模組101及膠框102黏貼在一起。由於使用膠帶103將顯示面板104及背光模組101黏貼在一起，使得在進行重新組裝時，需先將膠帶103撕下，且膠帶103無法重複使用，而且，在撕下膠帶103時，容易將背光模組101中的光學膜片撕裂或發生錯位，同時也容易因測試過程中的熱漲冷縮，由於光學膜片被膠帶103固定，容易造成光學膜片撕裂或發生錯位。FIG. 1A is a schematic diagram of the structure of a conventional display device, and FIG. 1B is a schematic cross-sectional view along A-A' of FIG. 1A. As shown in FIG. 1A and FIG. 1B, the display device 100 includes a backlight module 101, a plastic frame 102 is disposed adjacent to the backlight module 101, and the backlight module 101 and the plastic frame 102 are disposed on the housing 106. For example, the backlight module 101 can include a light source, a light guide plate, an optical film, etc. The housing 106 can be a metal material or a polymer material, and can be used to carry the backlight module 101 and the plastic frame 102, and can also be used as the display device 100. The appearance of the shell. The chevron tape 103 is formed on the backlight module 101 and the plastic frame 102. Polarizers 105 are formed on the upper and lower surfaces of the display panel 104. The display panel 104 and the polarizer 105 are stacked on the backlight module 101 and passed through the chevron tape 103 is adhered to the backlight module 101 and the plastic frame 102 together. Since the tape 103 is used to stick the display panel 104 and the backlight module 101 together, the tape 103 needs to be removed first when reassembling, and the tape 103 cannot be reused. Moreover, when the tape 103 is removed, it is easy to remove The optical film in the backlight module 101 is torn or misaligned, and it is also easy to shrink or shrink due to thermal expansion and contraction during the test. Since the optical film is fixed by the tape 103, the optical film is easily torn or misaligned.

因此，如何能夠不使用膠帶而更方便的將顯示面板與背光模組進行組裝，且容易重新加工，提高生產效率，實為目前顯示裝置在製作上亟待克服的課題之一。Therefore, how to assemble the display panel and the backlight module more conveniently without using adhesive tape, easy to reprocess, and improve production efficiency is actually one of the problems to be overcome in the current display device manufacturing.

圖3是本發明另一實施例顯示裝置的剖面示意圖。結合圖2B、圖3所示，與圖2B所示實施例不同之處在於，圖3所示實施例中，第一膠框2021的下表面上形成上凸台2023，第二膠框2022的上表面上形成下凸台2024，在第一膠框2021與第二膠框2022對接時，上凸台2023和下凸台2024之間相互卡接，能夠有效地避免第一膠框2021與第二膠框2022之間發生錯位，能夠更準確地進行對接。3 is a schematic cross-sectional view of a display device according to another embodiment of the invention. With reference to Figures 2B and 3, the difference from the embodiment shown in Figure 2B is that in the embodiment shown in Figure 3, an upper boss 2023 is formed on the lower surface of the first plastic frame 2021, and the second plastic frame 2022 A lower boss 2024 is formed on the upper surface. When the first rubber frame 2021 and the second rubber frame 2022 are butted, the upper boss 2023 and the lower boss 2024 are clamped with each other, which can effectively avoid the first rubber frame 2021 and the second rubber frame 2022. The two plastic frames 2022 are misaligned, which can be more accurately connected.

圖4是本發明又一實施例顯示裝置的剖面示意圖。結合圖3、圖4所示，與圖3所示實施例中的凸台不同之處在於，圖4所示實施例中，第一膠框2021的下表面上形成卡接槽2025，第二膠框2022的上表面上形成卡接條2026，在第一膠框2021與第二膠框2022對接時，卡接條2026和卡接槽2025之間相互卡接，能夠有效地避免第一膠框2021與第二膠框2022之間發生錯位，能夠更準確地進行對接。本實施例中，卡接條2026的形狀為方形，其也可以是倒梯形、弧形等，卡接槽2025的形狀與卡接條2026的形狀相對應。另外，本實施例中以卡接條2026的數量為一條為例，當然，也可以根據膠框202的寬度，設置多條，本發明並不以此為限。4 is a schematic cross-sectional view of a display device according to another embodiment of the invention. 3 and 4, the difference from the boss in the embodiment shown in FIG. 3 is that, in the embodiment shown in FIG. 4, a clamping groove 2025 is formed on the lower surface of the first plastic frame 2021, and the second A clamping strip 2026 is formed on the upper surface of the rubber frame 2022. When the first rubber frame 2021 is connected to the second rubber frame 2022, the clamping strip 2026 and the clamping groove 2025 are clamped to each other, which can effectively avoid the first glue A misalignment occurs between the frame 2021 and the second plastic frame 2022, and the docking can be performed more accurately. In this embodiment, the shape of the clamping strip 2026 is square, which may also be an inverted trapezoid, arc shape, etc., and the shape of the clamping groove 2025 corresponds to the shape of the clamping strip 2026. In addition, in this embodiment, the number of clip strips 2026 is taken as an example. Of course, multiple strips can also be provided according to the width of the plastic frame 202, and the present invention is not limited thereto.

在上述的實施例中，第一膠框2021與第二膠框2022的硬度可為相同或不同，其中，由於第一膠框2021由於要容納顯示面板204，其硬度應較小，邵氏硬度介於80-90A之間。第二膠框2022可以採用傳統的膠框，也可以採用和第一膠框2021相同的材質，邵氏硬度介於80-90A之間。In the above-mentioned embodiment, the hardness of the first plastic frame 2021 and the second plastic frame 2022 may be the same or different. Since the first plastic frame 2021 needs to accommodate the display panel 204, its hardness should be smaller. Between 80-90A. The second plastic frame 2022 can be a conventional plastic frame, or the same material as the first plastic frame 2021, and the Shore hardness is between 80-90A.

本發明的顯示裝置，不僅能夠易於組裝，方便重新加工，且可以節省材料，提高生產效率，而且由於不使用傳統膠帶，還能夠減小顯示裝置的厚度，例如膠帶的厚度，約0.03-0.08mm。The display device of the present invention can not only be easily assembled and reprocessed, but also can save materials and improve production efficiency. Moreover, since traditional tape is not used, the thickness of the display device can be reduced, for example, the thickness of the tape, about 0.03-0.08mm .

當然，本發明還可有其它多種實施例，在不背離本發明精神及其實質的情況下，熟悉本領域的技術人員當可根據本發明作出各種相應的改變和變形，但這些相應的改變和變形都應屬本發明的申請專利範圍所保護的範圍。Of course, the present invention can also have various other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and All deformations should fall within the scope of protection of the patent application of the present invention.
