Problems solved by technology

[0003] Usually, when performing the binding process, first use pressure-sensitive paper to judge the flatness of the binding indenter, and then confirm the binding of several samples. After confirming that there is no problem with the binding of the several samples, the The confirmation result is the benchmark for continuous binding operations. Therefore, real-time monitoring of the position of the binding indenter and the flatness of the display panel binding area cannot be achieved in continuous binding operations. When the binding indenter is tilted or the display panel is bound When the fixed area is uneven, it is easy to cause inaccurate binding alignment, resulting in poor contact or failure of electrical signals between the drive circuit and the display panel, and eventually resulting in waste products
