Problems solved by technology

[0003] The quality of the mobile phone display directly determines the quality of the mobile phone. With the prevalence of electronic life, the mobile phone is an essential electronic device for everyone. It is also a major problem for the later maintenance of the mobile phone. The most common is the damage of the mobile phone screen, and the mobile phone screen Compression damage is relatively common. In order to improve the service life of mobile phones, the pressure resistance of the screen must be guaranteed. Therefore, after the production of mobile phone screens is completed, it is necessary to conduct sampling tests on them. However, the current test equipment is too simple and the test method is single. , it is not convenient to realize high-precision and high-compatibility testing

Abstract

The invention discloses a mobile phone display screen pressure resistance testing device and a using method thereof. The mobile phone display screen pressure resistance testing device comprises a main frame and a controller, the controller is installed on the surface of the main frame, a pressing device capable of applying pressure at high precision is installed at the top of the main frame, and a testing device capable of converting stations is installed at the bottom of the pressing device; four testing rods are evenly installed outside the testing device, and the controller is electrically connected with the bearing device and the pressing device. The pressing device drives the testing rods to conduct pressure testing on a screen, operation of two modes can be conducted, pressure can be directly applied to the screen till the screen is abnormal, the maximum pressure resistance value of the screen is obtained, a rated pressure value can be set through the pressure sensor, stable pressure application testing is carried out in a required range, the operation modes are rich, the testing selectivity is multiple, the practicability is high, the testing compatibility for different screens is high, meanwhile, the testing device is convenient to change positions, the operation of multi-station testing is simplified, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of display screen testing, in particular to a mobile phone display screen withstand voltage testing device and a use method thereof. Background technique [0002] The phone screen, also called the display screen, is used to display images and colors. The screen size is calculated according to the diagonal of the screen, usually in inches (inch), which refers to the length of the diagonal of the screen. With the increasing popularity of mobile phone color screens, the material of mobile phone screens is becoming more and more important. [0003] The quality of the mobile phone display directly determines the quality of the mobile phone. With the prevalence of electronic life, the mobile phone is a necessary electronic device for everyone. It is also a major problem for the later maintenance of the mobile phone. The most common is the destruction of the mobile phone screen. It is relatively common to be dama...
