Abstract

The invention relates to a touch screen. The touch screen is characterized by comprising a bottom electrode face, a double-faced glue line, a top electrode face, an optical clear adhesive (OCA) glue line, a panel, and a silicon glue line. The manufacturing process includes the following steps: painting the top electrode face and the bottom electrode face, adhering the top electrode face to the OCA glue line, adhering the bottom electrode face to the double-faced glue line, assembling the top electrode face with the bottom electrode face, and applying the silicon glue line for coating. The touch screen has the advantages that joints among the top electrode face, the bottom electrode face, the OCA glue line, and the panel are covered by the silicon glue line, so that functions of sealing and reinforcing the joint parts of the touch screen are played. Special process and conditions are applied, so that a seal effect of the touch screen reaches an optimum state to meet the storage and work of the touch screen in a high atmospheric pressure environment.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a touch screen that can withstand high pressure environments. Background technique [0002] With the widespread use of touch screens, people's understanding and requirements for touch screens have become more and more stringent. In order to meet the needs of consumers, touch screens must be able to adapt to a variety of harsh environments at the same time, especially military touch screens, which have stricter requirements on product durability. At present, there are touch screens that have begun high-pressure resistance testing. The main testing methods are soft pressure testing, decompression testing, and vacuum testing. question. At this stage, domestic first-tier brands have strict testing and verification procedures for touch screens. The test items include various aspects such as function, durability, appearance, airtightness and so on. The present invention mainl...
