Method and system of testing result displayed on terminal screen
A screen display and test terminal technology, which is applied in the direction of digital output to display devices, static indicators, TVs, etc., can solve the problems of difficulty in displaying results in local areas, low accuracy, and complex systems, so as to reduce the amount of transmitted data and reduce Processing link, the effect of simplifying the system

Embodiment 1
[0059] see figure 2 The method for testing terminal screen display provided by the present invention specifically includes the following steps:
[0060] Step 101: The terminal internally converts the screen display results into data and saves them. The saved data is actually the image of the screen display results in memory in a certain way;
[0061] Taking a monochrome screen as an example, each pixel on the screen is represented by 1 bit, "1" means black, "0" means white, and the bits of all pixels on the screen follow a certain order (such as from Arranged together from top to bottom, from left to right), you can get an array, which is the screen data area, which can be considered as a virtual screen;
[0062] In order to further improve efficiency, usually the terminal will internally synchronize the results into data and save them while displaying the results on the screen. Of course, in actual applications, it may not be synchronized, but it will not affect the test ef...
Embodiment 2
[0077] see image 3 , the present invention also provides another method for testing the screen display of the terminal. The difference from Embodiment 1 is that the terminal directly transmits the screen display result data to the control device, and the control device extracts the data in the area to be compared. The method specifically includes the following steps:
[0078] Step 201: The terminal internally converts the screen display results into data and saves them;
[0079] Step 202: the terminal transmits the saved screen display result data to the control device;
[0080] Step 203: After receiving the data, the control device extracts the data in the area to be compared by masking or other processing methods;
[0081] Step 204: The control device compares the extracted data in the area to be compared with the data of the correct display result of the area to be compared that is pre-stored in the control device using the same conversion method as in step 201.
Embodiment 3
[0083] see Figure 4 , the present invention also provides another method for testing the screen display of the terminal, which is different from the second embodiment in that the terminal processes the screen display result data before transmitting it to the control device, so as to reduce the amount of data transmission between the terminal and the control device , the method specifically includes the following steps:
[0084] Step 301: The terminal internally converts the screen display results into data and saves them;
[0085] Step 302: The terminal first processes the saved screen display result data, such as compression processing, and then transmits it to the control device;
[0086] Step 303: After receiving the data, the control device first restores the screen display result data, such as decompression processing, and then uses masking or other processing methods to extract the data in the area to be compared;
[0087] Step 304: The control device compares the ext...
