As shown in the figure, the system for testing the external display interface of the test notebook of the present invention comprises a notebook computer 1, an external display 2 and a camera device 3. The external display 2 is connected to the notebook computer 1 through an external display interface; the camera device 3 is connected to the notebook computer 1 through a data line.

The camera device 3 can employ a USB camera or an analog camera.

Specifically, the method for testing the external display interface of the test notebook of the present invention comprises the following steps:

Step S1: switching the display of the notebook computer to the external display mode, and displaying the plural two-dimensional code on the external display screen;

Preferably, since the display effects on the four corners of the display are unstable and susceptible, four four-dimensional codes are displayed on the four corners of the external display to better test the external display interface of the notebook. At the same time, a two-dimensional code is displayed in the center of the external display. Among them, the central two-dimensional code is divided into four parts. The four QR codes of the four corners and the central two-dimensional code can be in any of the following formats:

(1) The four two-dimensional codes of the four corners are black and white two-dimensional codes whose base color is white, and the four parts of the central two-dimensional code are respectively colored two-dimensional codes of red, blue, white and green. ;

(2) The four two-dimensional codes of the four corners are respectively colored two-dimensional codes of red, blue, white and green, and the central two-dimensional code is a black and white two-dimensional code whose base is white.

Among them, the black and white two-dimensional code is used to test the image offset, and the color two-dimensional code is used to test the image heterochromatic. The four parts of the central two-dimensional code can be equal or large.

Step S2: using a camera to capture an image on an external display screen;

Step S3: analyzing the two-dimensional code in the image captured by the camera, and decoding the two-dimensional code, and determining whether the captured image includes all the two-dimensional codes displayed on the external display at the same time;

Specifically, first, the pixel weight is obtained from the RGB values of each primitive point of the two-dimensional code in the captured image, that is, the pixel weight V=R/3 + G/3 + B/3. If V is less than the preset value, V is 0; if V is greater than or equal to the preset value, V is 255. That is, a grayscale two-dimensional code image of the two-dimensional code image in the captured image is obtained. The preset value may be determined according to an operation experience or a structure of a two-dimensional code. For example, if the preset value is 40, then when V<40, V takes a value of 0; when V>=40, V takes a value of 255.

Then, the generated gray-scale two-dimensional code image is decoded, and if all the two-dimensional codes can be decoded, it is determined that the captured image includes all the two-dimensional codes displayed on the external display, if there is one or Some two-dimensional codes cannot be decoded, and it is judged that all the two-dimensional codes displayed on the external display are not included in the captured image.

The principle of judging whether the two-dimensional code can be decoded is as follows: if the background color of the two-dimensional code is not displayed or displayed poorly, the pixel point corresponding to the background color is displayed as black in the gray-scale two-dimensional code image; In the two-dimensional code image, the color of the ground color and the two-dimensional code are both represented as black, which causes the gray-scale two-dimensional code image to be unable to be decoded.

Step S4: If all the two-dimensional codes displayed on the external display are included, it is judged that the external display interface of the current notebook computer is good, and the test ends; otherwise, the process proceeds to step S5;

Step S5: determining whether the test time exceeds the rated test time. If the rated test time is not exceeded, the steps S1-S4 are repeated; if the rated test time is exceeded, it is determined that the external display interface of the current notebook computer is bad, and the test ends.

In summary, the system and method for testing the external display interface of the test notebook computer of the present invention no longer need to manually view the display effect of the external display, and avoid subjective judgment on the display effect; meanwhile, the external camera is used to analyze the external display. The display effect enhances test coverage, improves test efficiency, and reduces labor costs. Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

The above-described embodiments are intended to illustrate the principles of the invention and its effects, and are not intended to limit the invention. Any of the above-described embodiments can be modified by those skilled in the art without departing from the spirit and scope of the invention.
