Method for testing display data of electronic cipherer COB circuit board

The invention discloses a method for testing display data of an electronic cipherer COB circuit board. The method for testing the display data of the electronic cipherer COB circuit board comprises the steps that a normal display waveform of the display data of the electronic cipherer COB circuit board is preset and stored by a computer; a test display waveform of the display data of the electronic cipherer COB circuit board is acquired by a data acquisition card; the test display waveform is sent to the computer by the data acquisition card; the test display waveform is compared with the normal display waveform by the computer so that whether the test display waveform is normal or not can be judged; a result indicating whether the test display waveform is normal or not is displayed by the computer on a computer display. According to the method for testing the display data of the electronic cipherer COB circuit board, the computer replaces a tester to test the waveform of the display data of an electronic cipherer in a COB circuit board stage, so that the test efficiency is improved and the test result is accurate and reliable.
