With the increase in user demand, the requirements for the screen-to-body ratio of mobile phones are getting higher. The level of display development in the smartphone industry is extremely high. Over the past few years, there has been a serious pursuit of full-screen devices. We have seen the notch design, waterdrop, punch-hole design, pop-up camera, and other solutions.
