Problems solved by technology

The existing technology cannot automatically judge whether there is a "ghost finger" fault on the touch screen, and can only be compared and judged artificially based on the touch operation and touch response, which leads to large judgment errors and low efficiency

Embodiment Construction

[0029] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Please refer to figure 1 ,Should figure 1 Shown is the flow chart of the first embodiment of the touch screen testing method of the present invention.

[0031] to combine image 3 Schematic diagram of the principle, figure 1 The process of testing the touch screen in the embodiment is as follows:

[0032] Step 101: the process starts.

[0033] Step 102: Display multiple touch areas on the touch screen.

[0034] In this embodiment, a plurality of touch areas are firstly displayed on the touch screen before testing. The touch area can be the area that is preset and stored by the tester, and is directly called and displayed from the storage unit during use, or it can be set and displayed by the tester before each test. The number and position of the touch areas can be adjusted according to test re...

Abstract

The invention discloses a test method and a test device of a touch screen. The test method includes displaying a plurality of touch areas on the touch screen, pressing a part of the touch screen or all the touch areas, reading the number of the pressed touch areas as the set number when correctly pressing the corresponding touch areas, then continuous pressing the areas for set time, detecting the pressed touch area number as the actual number after the set time is reached, comparing the actual number with the set number and judging whether the touch screen has faults or not according to comparison results. The test method and the test device achieve automatic detection and judgment of the faults of the touch screen and improve judgment accuracy and detection efficiency.

Description

technical field [0001] The invention relates to the technical field of screen testing, in particular to a touch screen testing method and testing device. Background technique [0002] The touch screen needs to be tested before leaving the factory to detect the quality of the touch screen itself and the stability of the connection with the motherboard. Alternatively, the touch screen also needs to perform corresponding detection after a fault occurs. In the touch screen testing process, it is particularly important for the detection of the touch screen to quickly and accurately determine whether the touch screen is faulty and the type of the fault. [0003] One of the most prone to failures on the touch screen is "ghost fingers", that is, when n touch points on the touch screen are pressed, more than n touch points will appear on the screen, that is, more than the actual number of touch points will appear. touch point. The existing technology cannot automatically judge whe...
