[Prior Art] In the manufacture of liquid crystal displays (LCDs), many components need to be accurately placed to match the age of the components. Taking the integrated circuit (1C) of the LCD as an example, the drive 1 (: is accurately pressed to the corresponding position of the substrate via a high-temperature and high-pressure pressing process; before the press-fitting, an alignment is required. The action 'solution method is based on (4) the corresponding mechanism on the ic and the substrate, and after the alignment, the mutual face is combined. However, in the coupling process, mechanical or human error is inevitable, and the misalignment is generated. Therefore, it is necessary to observe the offset condition, so as to recalibrate the machine. In the conventional substrate and drive 1C offset condition detection mode, the operator directly observes the pair of the opposite substrate on the drive IC by the microscope. The position on the bit mark. When the offset occurs, the offset condition is estimated first, and the machine is adjusted accordingly. However, as the industrial automation requirements continue to increase, in the LCD manufacturing industry, such as film Flip chip (dlip_Qn_fllm; C()F) substrate and printed circuit board ((4) ^ board; PCB), or drive Ic and substrate _ alignment components need to use a specific device to automatically calculate the offset from the _ cis The adjustment of the machine can be performed at the time of the offset.
