Description

technical field [0001] The application of the present invention relates to the technical field of liquid crystal screen testing, in particular to a multifunctional liquid crystal screen testing machine. Background technique [0002] Usually, there are two ways to test whether a LCD screen is good or bad. One is to test by purchasing the original motherboard corresponding to the LCD screen. This method is not only expensive, easy to break, and extremely inconvenient. The other is a custom-made test rack. The traditional custom-made test rack is bulky, cumbersome to operate, and inconvenient to carry, which greatly affects the test efficiency. At present, the domestic ones are very large, and each test stand can only test one kind of LCD screen. Contents of the invention [0003] The purpose of the application of the present invention is to provide a multifunctional liquid crystal screen testing machine for the above-mentioned deficiencies in the prior art. [0004] The te...
