System and method for testing notebook computer external display port

Abstract

The invention provides a system and method for testing a notebook computer external display port. The system at least comprises an external displayer, a camera device and a notebook computer. The external displayer is connected with the notebook computer through the external display port of the notebook computer and used for displaying a plurality of two-dimension code images. The camera device is connected with the notebook computer and used for shooting images displayed on the external displayer. The notebook computer is used for controlling the external displayer to display the two-dimension code images, and analyzing the images shot by the camera device so as to judge whether the external display port of the notebook computer is normal or not. According to the system and method for testing the notebook computer external display port, the display effect of the external displayer does not need to be checked by persons, and subjective judgment on the display effect is avoided; meanwhile, the external camera is utilized for analyzing the display effect of the external displayer, the testing coverage rate is increased, the testing efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a testing system and method for digital equipment, in particular to a system and method for testing an external display interface of a notebook computer. Background technique [0002] The external display interface of the notebook computer includes video display adaptation interface VGA, high-definition multimedia interface HDMI, high-definition digital display interface Display Port, digital display interface DVI and other types. In the production of notebook computers, it is necessary to test the display effect of the external display interface of the notebook computer. [0003] During the test of the external display interface of the notebook computer, the following problems usually occur: [0004] a. The external display interface is damaged and cannot be switched to the external display; [0005] b. The pins of the external display interface are damaged, resulting in problems such as different colors, stripes, and water ...

AI Technical Summary

Problems solved by technology

[0010] (1) The above test methods require the purchase and maintenance of an external display, which is expensive to purchase and maintain;

[0011] (2) The above test method requires the operator to check the display effect of the external monitor and use the keyboard to input random numbers, which leads to long test time and low efficiency, and increases the labor cost generated by the laptop;

[0012] (3) The above-mentioned test method is mainly to judge the display results artificially, which leads to too strong subjectivity of the test results;

[0013] (4) The foolproofness of the above test method is not enough, the operator often only pays attention to the random numbers, and ignores the observation of the display effect displayed on the external monitor
