[0002] Touch screen rainbow pattern refers to a color stripe or spot effect that appears on the surface when observing or using the touch screen. This rainbow pattern is usually caused by the refraction, reflection and interference of light on the touch screen surface. Although the rainbow pattern usually does not affect the normal function of the touch screen, it will affect the visual experience to a certain extent. Manufacturers usually reduce the rainbow pattern on the touch screen surface by optimizing the design and production process to improve product quality and user experience.
[0003] The existing technology has the following deficiencies: the rainbow patterns may come from the touch screen itself or from the protective film on the surface of the touch screen. Therefore, during inspection, the staff needs to observe with their eyes to determine whether the rainbow patterns come from the touch screen itself, so as to specify a specific maintenance plan. Since there are many light sources in the real environment and the polarization directions of the light are different, when the staff observes the rainbow patterns on the touch screen surface, they will be affected by stray light of various polarization directions, resulting in unclear rainbow patterns and difficulty in observation, which increases the difficulty of resolution. This not only affects the inspection efficiency of the touch screen, but also easily causes sore eyes to the staff, which is harmful to the staff's health.
