Embodiment 1
[0054] Such as figure 2 As shown, the drive interface of the TCON board of this system is connected with the input interface of the TCON board to be tested, the output interface of the TCON board to be tested is connected with the signal detection interface of the TCON board of the system, and the programming interface of the TCON board of the system is connected with the The programming interface of the TCON board to be tested is connected, the barcode printing control interface of the system is connected with the barcode printer, the test data output interface of the system is connected with the display device, and the display device refers to a computer monitor or an LCD screen.
Embodiment approach 1
[0055] The flow chart of Embodiment 1 is as follows image 3 As shown, the system first burns the firmware program of the TCON board into the TCON board to be tested through the TCON board program burning interface, and then first judges whether the burning is successful. If the burning fails, the system will skip the subsequent test steps and directly output the burning Record failed results and end the test process, thereby saving test time. If the programming is successful, the system will reset or restart the TCON board under test and provide the TCON board under test with the required input excitation signal and power through the TCON board drive interface, and then the system will receive the TCON board under test through the signal detection interface of the TCON board. The output signal of the board, and detect the received signal, and then the system outputs the detection result to the user through the user interaction device or the test data output interface, and con...
Embodiment 2
[0057] Such as Figure 4 As shown, the test data output interface of this system is connected with the existing main board detection system, which is used to realize the detection of TCONLESS main board. The TCON output interface of the TCONLESS main board to be tested is connected to the TCON board signal detection interface of this system, the TCON board program burning interface of this system is connected to the burning interface of the TCONLESS main board to be tested, and the barcode printing control interface of this system is connected to the barcode printer connected. The signal input interface and other signal interfaces of the TCONLESS main board to be tested are connected with the existing main board detection system. Existing motherboard detection system refers to the invention patent of a method and device for automatically detecting the main control board of 4K2K products (application number: 201310277188.X) or LCD TV and LCD driver board detection system (appl...
