Description
本發明關於顯示裝置技術領域,具體地說,是關於一種顯示裝置的組裝結構。 The present invention relates to the technical field of display devices, and in particular to an assembly structure of a display device.
傳統的LCM(Liquid Crystal Display Module,液晶顯示裝置)主要包括背光模塊、顯示模塊以及蓋板,其中,TFT(Thin Film Transistor,薄膜晶體管)基板與CF(Color Filter,彩色濾光板)基板之間用框膠黏接以密封液晶而形成顯示模塊,顯示模塊的上下各設置一張偏光片,上偏光片通過OCA(Optically Clear Adhesive,光學膠)與蓋板黏接,下偏光片通過膠帶與背光模塊黏接。 The traditional LCM (Liquid Crystal Display Module, liquid crystal display device) mainly includes a backlight module, a display module, and a cover plate. Among them, a TFT (Thin Film Transistor) substrate and a CF (Color Filter) substrate are used The frame glue is adhered to seal the liquid crystal to form a display module. A polarizer is provided on the upper and lower sides of the display module, the upper polarizer is adhered to the cover plate through OCA (Optically Clear Adhesive, optical glue), and the lower polarizer is connected to the backlight module through tape Bonding.
在做整機物理測試時,蓋板與背光模塊上會施加受力方向相反的外力。一般情況下,由於蓋板通過OCA和CF基板形成一個整體,而背光模塊通過膠帶與TFT基板形成另外一個整體,這兩個整體之間黏接的強度都大於框膠作用於CF基板與TFT基板的黏接強度,故當兩個相反的外力作用且大於框膠黏接力時,容易使CF基板和TFT基板在框膠黏接位置出現分離或鬆動。現有技術解決此問題的方法 一般是增加框膠的黏接強度,但是,仍存在相當程度的產品不良率。 In the physical test of the whole machine, the cover plate and the backlight module will exert external forces in opposite directions. In general, since the cover plate is formed as an integral body by the OCA and CF substrates, and the backlight module is formed as another integral body by the tape and the TFT substrate, the bonding strength between the two integrals is greater than that of the frame glue acting on the CF substrate and the TFT substrate The bonding strength of the adhesive, so when two opposing external forces act and are greater than the adhesive force of the frame glue, it is easy to make the CF substrate and the TFT substrate separate or loosen at the frame glue adhesion position. Existing techniques to solve this problem Generally, the adhesion strength of the frame glue is increased, but there is still a certain degree of product defect rate.

於一實施例中,如圖5所示,連接塊150更包括下表面151,連接塊150的下表面151通過雙面膠104黏接背光模塊130。詳細來說,連接塊150的下表面151以及第二面板120分別黏附於雙面膠104上。其中,雙面膠104例如是具有遮光功能的遮光雙面膠帶。
In an embodiment, as shown in FIG. 5, the connection block 150 further includes a
於一實施例中,如圖3和圖5所示,連接塊150位於第二面板120的第二面板側邊120a與背光模塊130的背光模塊側邊130a之間,其中,連接塊150與第二面板側邊120a之間具有距離P1,連接塊150與背光模塊側邊130a之間具有距離P2,且距離P1大於距離P2。
In an embodiment, as shown in FIGS. 3 and 5, the
於連接塊150與第二面板120之間設置的距離P1能夠避免連接塊150與第二面板120摩擦或向第二面板120滲膠等問題。
The distance P1 provided between the
於一實施例中,連接塊150可與背光模塊130的至少一側邊齊邊,以使連接塊150的下表面151與上表面152貼附面積最大化。如圖6所示,連接塊150可與背光模塊130的背光模塊側邊130a齊邊。
In an embodiment, the
