Abstract

The invention discloses a device for testing toughing screens, which is characterized in that the invention comprises computer equipment, a point pressure testing machine, and a measuring control adapting card. The invention also discloses a method for testing the touching screens, which comprises arranging a standard screen whose testing results have been known into the point pressure testing machine, inputting testing parameters into the computer equipment, testing the standard screen according to a test of a testing standard point, obtaining a testing standard value, storing the testing standard value into the computer equipment, arranging a testing touching screen into the point pressure testing machine, deciding and correcting the testing point of the testing screen, and testing the testing point, obtaining the testing results after comparing the testing value with the testing standard value, and storing and outputting the testing results. The invention can be used to eliminate the defects of testing results erroneous judgments due to machine positional errors of the point pressure testing machine, tests aren't limited into moving speeds; quality can be decided through only one test according to the touching screens in different types and dimension specifications.

Description

technical field [0001] The invention relates to a testing device and method, in particular to a touch screen testing device and method. Background technique [0002] With the popularity of computer equipment, input operations are simplified and portability is increased, and touch screens (Touch panels) have been widely used in daily life and can be seen everywhere. For example, a touch screen panel used in a computer screen, a touch tablet used for input, a touch digital tablet used in a computer or a mobile phone, etc., are all embodiments of the touch screen. Due to the delicate touch signal circuit inside the touch screen, an efficient and accurate quality management process must be adopted to ensure the reliability of the touch screen product. Therefore, the traditional manual testing of the touch screen is outdated, and a test device specially designed for the touch screen must be used for the test. [0003] The existing touch screen testing device and method are to c...
