[ technical field ] A method for producing a semiconductor device
The utility model relates to a liquid crystal encapsulating device for negative pressure capillary for in aspect of screen packaging technology.
[ background of the invention ]
With the continuous development and progress of the society and the continuous development of computer and multimedia application technologies, the touch screen is widely used as a transparent medium attached to the surface of a display, and has the advantages of easy use, firmness, durability, rapid response, space saving and the like, so that the touch screen is widely used in media tools such as computers or mobile phones and the like. By utilizing the touch screen technology, the operation of media such as a computer or a mobile phone can be realized by touching the interface in the display screen with fingers, so that the input and application programs are greatly simplified, and the zero-distance interactive operation is really realized. However, most touch screens on existing devices are configured by using liquid crystal touch screens. The liquid crystal touch screen adopts an OCA full-lamination adhesive mode which is mainly used for gluing adhesives of transparent optical elements. The liquid crystal screen comprises an LCD screen arranged below and a touch screen arranged on the LCD screen. And gully-shaped capillary tubes are formed around the LCD screen and the touch screen. Because the flowing performance of the viscose in the OCA full-gluing mode is poor, the bonding glue is difficult to fill in a capillary in a gully shape formed by the LCD screen and the touch screen, and bubbles are easy to generate in the capillary. And because the bonding performance of the bonding colloid is not strong, the risk of bounce is generated between the LCD liquid crystal screen and the touch screen inside the bonded touch screen. In addition, OCA full laminating glue mode is to the full subsides of large-size for production efficiency is low, and the cost of labor is high. In order to solve the above-mentioned existing technical problems, a conventional LOAC full-lamination liquid optically clear adhesive has appeared later, which mainly uses a special adhesive for adhering a transparent optical element. The liquid optical transparent adhesive is colorless and transparent, has the light transmittance of more than 98 percent and good bonding strength, can be cured at normal temperature or medium temperature, and has the characteristics of small curing shrinkage rate, yellowing resistance and the like. The liquid optical transparent adhesive is mainly suitable for laminating a large-size touch screen. But the following defects exist in the touch screen which is attached to the curved surface or the complex structure of the touch screen, the touch screen part with higher ink thickness and the touch screen with the attached uneven surface: 1. the LOCA optical cement in the local area is too much, and the LOCA optical cement overflows out of the bonding area and even permeates into the sheet of the backlight source, so that spot-shaped stains are caused on the display picture of the liquid crystal screen, namely the glue overflow phenomenon. 2. The LOCA optical cement is not filled enough, the whole binding surface is not completely covered, and a cavity with air exists in the part of the touch screen which is not changed, and the cavity can enter a display area, so that local picture color abnormity can be caused, namely the phenomenon of glue shortage is avoided. 3. The procedure of the laminating process is relatively complex, the processes of figure dispensing, pre-curing and curing are required, the product needs to be transported to different stations for three times or four times, the labor cost of production is high, and the operation procedure is relatively complex. 4. When the adhesive is dispensed, bubbles are easy to generate in the leveling process, namely the bubble generation phenomenon is generated. 5. In the process of easily generating leveling, the thickness of the leveled glue per unit area is different, namely the glue thickness is not uniform.
