The bad point is the wrong point. LCD displays the image with different refraction angles of each liquid crystal point. Therefore, when the refraction of a point is not correct, the light will not be correct, and this point is the bad point. Generally speaking, when using solid colors on LCD, if there are any defects, they can be seen immediately. I always look at five colors, namely red, green, blue, white and black.
