Problems solved by technology

[0002] In the screen inspection production line, it is necessary to perform signal testing on the aging stage of the screen production line, and test the neatly arranged screen arrays one by one through the loading test fixture on the aging trolley; A set of test fixtures can only test one screen at a time. If it is necessary to test all 160 screens in the screen array at the same time, it is necessary to load 160 sets of test fixtures on the aging trolley; and each time the screen of a model is replaced It is necessary to manually update the test program stored in each set of test fixtures. When the screen array is replaced as a whole and the model is changed, the test programs of 160 sets of test fixtures need to be updated one by one; this method is too manual and labor-intensive. , low production efficiency, high production cost

Embodiment 1

[0026] Such as figure 1 As shown, the traditional test fixture can only test one screen at the same time, that is, the traditional test fixture can only realize one-to-one detection; an aging trolley is loaded with multiple sets of test fixtures, when changing the screen model , it is necessary to update the test program one by one for each test fixture on the aging trolley, the operation is extremely cumbersome, the efficiency is low, and the production cost is high.

[0027] Such as figure 2 As shown, in one embodiment of the present invention, a kind of module signal generator based on multi-FPGA parallel output super multi-channel signal is disclosed, including the mainboard 1 comprising the FPGA module, the mainboard 1 has 128 pairs of LVDS resources, the The main board 1 outputs 8 groups of LVDS signals through the LVDS interface, and each group of LVDS signals is configured with 16 pairs of signals; each group of LVDS signals is electrically connected to a sub-board 2...

Embodiment 2

[0034] Such as image 3 As shown, the difference from the first embodiment is that in the second embodiment, after each group of LVDS signals sent from the daughter board 2 is replicated and expanded by the LVDS HUB chip 3, each group of LVDS signals copied will pass through The next-level sub-board 21 comprising the FPGA module is transferred to a new next-level duplication chip 31, which can also be selected to include 2 pairs of LVDS inputs and 10 pairs of LVDS HUB chips for LVDS output; Each group of LVDS signals sent by board 2 is expanded to 100 groups through secondary replication; each group of LVDS signals after secondary replication is electrically connected to a screen to be tested; thereby greatly increasing the number of controls.

[0035] It should be pointed out that in actual production work, each group of LVDS signals can be extended to more levels according to capacity requirements, not limited to two-level replication, so as to greatly increase the number of...

Embodiment 3

[0037] Such as Figure 4 As shown, the difference from the first embodiment is that in the third embodiment, the intermediate electric board 22 is connected between the main board 1 and the sub-board 2 as a transfer station, and each intermediate electric board 22 includes an FPGA module Each of the intermediate electric boards 22 is connected and communicated with the main board 1 through at least 6 pairs of input signals, and each of the intermediate electric boards outputs multiple sets of LVDS signals, and each set of LVDS signals includes at least 5 pairs of signals; each set of LVDS signals is connected to a The sub-board 2 is connected to communicate; realize the expansion connection between the main board 1 and the multi-level sub-board, thereby effectively increasing the number of controls; under this signal structure, it is still only necessary to control, adjust, and modify the test program through the main board 1 to realize aging Unified control of trolleys.
