[0035] Embodiment 2

[0036] Further, the application also provides a light halo prevention structure of a curved full-laminated touch screen. For a liquid crystal screen assembly, in order to make the liquid crystal screen assembly into a curved screen, the panel of the liquid crystal screen assembly needs to be laminated with a curved touch screen. First, the liquid crystal panel is placed in a fixing clamp. Due to the thinness of the liquid crystal screen, the liquid crystal screen will naturally bend. Then, the center part is laminated with the curved touch screen and gradually extends to both sides, so that the liquid crystal panels on both sides are laminated with the curved touch screen. As shown in Figure 7 , in the case that the liquid crystal glass panel bends to both sides with the same curvature, the stress on the liquid crystal panel will gradually increase, especially the edge parts on both sides. In the case that the liquid crystal panel is forcibly laminated on the touch screen, the liquid crystal molecules in the liquid crystal panel are prone to be damaged, which causes problems such as light halo and light spot in the screen display. Therefore, in order to solve the above problems, the application also provides a structure of a curved full-laminated touch screen, as shown in Figure 8As shown, including the middle curved part and both sides of the flat part, in the production of curved touch screen, still the center of the liquid crystal panel is attached to the center of the curved part, and then gradually extend to both sides of the liquid crystal panel gradually attached to the curved part, when also the middle area of the panel is completely attached to the curved part, the part located on both sides of the liquid crystal panel is no longer bent, but directly attached to both sides of the flat part. In this way, the part on both sides of the liquid crystal panel will not be damaged by bending under stress, and further cause the liquid crystal panel to appear halo, light spot and other display defects. By adding a touch component on the liquid crystal panel, people can directly control according to the position of the finger click, without the need of a handle to play games on the display.
