Background technique

Currently used in photovoltaic devices, plasma displays, organic light-emitting diodes and AMOLED (abbreviation of Active-matrix organic light emitting diode, Chinese full name is active matrix organic light-emitting diode or active matrix organic light-emitting diode), etc. The technology of sealing the sealing system of glue is generally to make the opening of the printing screen according to the design value of the glass glue. For example, the glass glue is 0.5 mm, and the opening of the screen plate is also 0.5 mm, wherein in a printing process, as shown in FIG. 1 As shown, the screen is pressed against the glass by the scraper and pressed into the glass. During the rebound of the screen, the glass glue is subjected to the action of the two sides of the emulsion. The glass glue on both sides is brought up to cause the glass glue on both sides to be higher. A groove will appear in the middle of the upper part, which will result in poor product viscosity and mechanical strength during the subsequent laser sintering process. In the process of printing glass glue, the glass glue has fluidity, so the glass glue will slide after the printing is finished. The glass glue on both sides is highly low, and the upper and lower glass cannot be effectively bonded during the subsequent laser sintering process, which may also cause the mechanical strength of the product to decrease.
