Processing method of ogs capacitive touch screen cover glass

Abstract

The invention relates to a touch screen cutting method for an electronic product, and mainly relates to an OGS (one glass solution) capacitive touch screen cover glass processing method. The OGS capacitive touch screen cover glass processing method comprises the following steps: step 1: manufacturing a protective layer with the thickness of 20-30 mm on a large OGS toughened glass plate, and sequentially drying the protective layer by roasting, exposing and developing the protective layer and toughening a membrane of the protective layer; and step 2: immersing the large OGS toughened glass plate processed in the step 1 into an etching solution with the temperature of 21-25 DEG C for etching the large OGS toughened glass plate into small OGS toughened glass plates. By the OGS capacitive touch screen cover glass processing method, the large OGS toughened glass plate can be etched into the single small OGSs, without a repairing process after the etching process; and the etched single small OGSs are high in size precision and high in qualified rate.

Description

technical field

[0001] The invention relates to a method for cutting and processing a touch screen of an electronic product, in particular to a method for processing an OGS capacitive touch screen cover glass. Background technique

[0002] The traditional capacitive touch screen is composed of two pieces of glass, one is a sensor flat glass with inductive capacitance and its circuit, and the other is a protective glass with high hardness requirements. The OGS technology is a transformational display touch technology, which mainly uses a piece of glass instead of two pieces of glass (or a piece of glass and a piece of film), that is, the capacitive sensor is directly fabricated on the window (cover glass). For the convenience of processing, usually a lot of small pieces of OGS are made on a large piece of strengthened glass, and then the small pieces of OGS are cut out. The cutting process will cause mechanical damage to the edge of the glass, so the small pieces of OGS after...

Embodiment 1

[0029] Step 1: Print an acid-resistant protective layer with a thickness of 20 mm on one of the front and back sides of a large OGS tempered glass plate with a thickness of 0.3 cm, and then sequentially bake and dry the acid-resistant protective layer. Drying is done in an infrared oven. The drying time is 25 minutes and the temperature is 130°C. After baking and drying, exposure, development, and film hardening are performed to form a follow-up on one side of the large OGS tempered glass plate. Etching patterns required when etching small pieces of OGS strengthened glass plates; using the same process steps on the other side of the large piece of OGS strengthened glass plates to form etching patterns required for subsequent etching of small pieces of OGS strengthened glass plates on the other side;

Embodiment 2

[0032] Same as Example 1, the difference is that the thickness of the large OGS strengthened glass plate in the first step is 0.4-0.5 cm; the etching width formed by etching in the second step is 0.6-0.7 cm.

Embodiment 3

[0034] Same as Example 1, the difference is that in the first step, an acid-resistant protective layer with a thickness of 25 mm is screen-printed on one of the front and back sides of the large OGS tempered glass plate.
