Touch screen testing method, testing system and stylus for executing touch screen testing method

Abstract

The invention discloses a touch screen testing method, a testing system and a stylus for executing the touch screen testing method. The touch screen testing method comprises the following steps: using the stylus with an adjustable touch area and at least a touch control point on the touch screen; aiming at each of the touch control point, when a touch control inductive signal is outputted by the touch screen, according to the touch control sensing signal, confirming the induction position inducted by the touch screen, and then comparing the error between the induction position and the actual position of the touch control point and a preset value, and determining the minimal touch area supported by the touch control point; at last, according to the acquired minimal touch area of each of the touch control point, determining the minimal touch area supported by the touch screen. According to the method, as the touch area of the adopted stylus is adjustable, the different touch areas can be adjusted to perform testing; the method can accurately determine the minimal touch area supported by the touch screen, so as to provide a test basis for the test standard in the touch screen industry.

Description

technical field [0001] The invention relates to the technical field of touch control, in particular to a method for testing a touch screen, a test system thereof and a touch pen. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. Therefore, as the application range of the touch screen becomes wider and wider, the test standard of the touch screen also needs to be gradually optimized and determined in order to carry out better testing and specification. [0003] As we all know, for touch screens designed and produced by different manufacturers, especially the most common capacitive touch screens at present, the minimum touch areas supported by them are different. The current common method is to directly use the design length between the touch terminals to determine the minimum touch area supported by the touch screen, such as figure 1 As shown, it is a schematic d...

Problems solved by technology

[0005] However, at present, there is no particularly accurate test method and equipment for the smallest finger that the touch screen can support for touch. It is only determined according to the touch distance of the touch screen itself or tested by the feeling of fingers of different sizes.

However, the use of finger tests is neither accurate nor standardized to form industry standards

Moreover, with the development of touch technology, passive touch pens have appeared, such as ordinary pencils, which can realize the touch function. Obviously, it is not accurate and reasonable to determine the minimum touch area supported by the touch screen through the touch feeling of fingers. of
