Recently, we have customers come to consult the customized capacitive touch panel. The 10.1-inch touch screen that customers need to purchase is used in smart homes. Then the customer bought the touch screen from another home and experienced quality problems. So I wanted to change the supplier of touch screens and found us. Therefore, the customer pays great attention to the quality control of the touch screen. He asked how our capacitive touch screens are tested. So let's talk about how to test the capacitive touch screen today?
To determine whether a capacitive touch screen is a good product. It needs to go through a series of system tests before it can be shipped. Then the technical indicators of the capacitive touch screen produced by each touch screen manufacturer are different. And the test software is different. As a professional touch screen manufacturer, we usually get the manual and product source code from the IC supplier and develop the test program ourselves.
Generally, there are three types of specific equipment,
2) to have a communication conversion adapter,
3) to have a test fixture,
Both the computer and the fixture are easy to do. Only the communication adapter can be developed only when the development source code is obtained. Otherwise, there can't use it for testing a simple thing . Now our company does product development and testing, which can quantify the test results. But this amount is not a number, but one or more sets of data. Including the sensing range, the resistance value of the circuit, the communication, and the path short circuit, and the mutual interference value and so on. It depends on how many touch matrices are on your screen.
We generally test the semi-finished products for SENSOR circuit continuity. Ensure that the SENSOR is good before hot pressing. FPC conduction test and finished electrode test.
Accuracy linearity, sensitivity, linearity, response speed, anti-interference ability, compression resistance, high and low temperature resistance, anti-moulding, salt spray, explosion-proof and anti-cracking tests.
