Example Embodiment
[0052] Example 1
[0053] (1) Cutting, edging and cleaning the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-e glass, high visible light transmittance glass, etc.
[0054] (2) Use a mechanical drill bit or a laser drilling machine to make an exhaust hole with a diameter of 2mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the back substrate glass.
[0055] (3) Use screen printing to make isolation support points on the back substrate glass. A non-crystalline low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a thermal expansion coefficient slightly smaller than the thermal expansion coefficient of the glass panel and an organic solution are used to prepare a paste with rheological properties suitable for screen printing. Then, a screen printing ...

[0062] Example 2
[0063] (1) Cutting, edging and cleaning the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-e glass, high visible light transmittance glass, etc.
[0064] (2) Use a mechanical drill bit or a laser drilling machine to make a 1mm diameter vent hole on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the back substrate glass.
[0065] (3) Use screen printing to make isolation support points on the back substrate glass. A non-crystalline low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a thermal expansion coefficient slightly smaller than that of the glass panel and an organic solution are used to prepare a paste with rheological properties suitable for screen printing. Then, a screen printing method is used to print wet film dots with ...
