Embodiment Construction

[0057] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] The structural representation of the test device embodiment of the present invention is as figure 1 shown. The test device is connected with the PDP chip to be tested, automatically tests the input / output parameters of the PDP chip to be tested, stores and displays the test results. The test device includes: a display terminal, a main processor, a digital logic module, a chip power supply module, a multi-way selection switch and a power pin test module. The main processor connects the chip power supply module through the enable line, controls the chip power supply module to enter the power supply state, and configures the chip power supply module to output working power to the power pins of the PDP chip, that is, the low-voltage logic power supply pin VDL and the high-voltage power supply of the PDP chip Pin VDH.

[0059] The chip power supp...
