Beschreibung
Zusammenfassung:	The utility model discloses a power-on aging test device of liquid crystal display modules. The power-on aging test device comprises a test board arranged outside an ageing test box and a data receiving board arranged inside the ageing test box. The test board is connected with the data receiving board through a serial port extension line. The test board comprises a test data transmitting module and a first level conversion module. The data receiving board comprises a second level conversion module, a series-parallel conversion module and a plurality of test ports connected with the liquid crystal display module to be tested. The power-on aging test device has the advantages that by providing the test board outside the ageing test box, continuous running of the test board is guaranteed, and power-on ageing testing is achieved; meanwhile, the test board and the data receiving board are connected through the serial port extension line, spacing between the test board and the data receiving board is greater than 15m, and ageing test convenience is greatly improved.
