AI Technical Summary

Problems solved by technology

If the difference between the injection amount and the optimum value becomes large, the balance between the refraction index and the driving electric field designed in advance of the liquid crystal display element will collapse, and display defects such as the occurrence of spots and poor contrast will occur.
In particular, it is difficult to control the deviation from the optimum value within a certain range since the optimum liquid crystal injection amount is small in the small liquid crystal display elements that are often used in the recently popular smartphones.
