Embodiment Construction
[0043] see figure 1 As shown, this figure is a schematic flow chart of the first preferred embodiment of the visual alignment method for non-corresponding substrates of the present invention. The visual alignment method 1 of the non-corresponding substrate includes the following steps:
[0044] Step 11 - providing a first alignment substrate and a second alignment substrate;
[0045] Step 12 - selecting at least two first feature points on the first alignment substrate and calculating at least one first pair of positional points having a relative positional relationship with the at least two first feature points;
[0046] Step 13 - selecting at least two second feature points on the second alignment substrate and calculating at least one second alignment point having a relative positional relationship with the at least two second feature points; and
[0047] Step 14 Select a corresponding position and teach the first alignment substrate to align with the second alignment sub...
