In the fiercely competitive mobile phone industry, consumers have continuously improved the appearance, thickness, display effect, battery life and functionality requirements of mobile phones, driving a steady stream of technological innovation, introduction and iteration. Display technology is an important part of many technologies because it directly affects consumers' perception and experience. With the development of OLED screen technology in recent years, the proportion of models using OLED screens has been increasing year by year, among which high-end models are the main ones.
OLED has the characteristics of high contrast, good black performance, wide viewing angle, wide color gamut, power saving, light and thin, and can be bent. It is considered as the next generation of emerging display technology. Of course, behind the high picture quality and good color it brings, OLED screens also have some shortcomings. For example, the most common drop problem encountered by mobile phones: Since OLED screens are thinner than traditional LCD screens, they are more likely to be damaged when dropped, and then problems such as broken screens, bright spots, and mold printing will occur, affecting user experience. However, the drop of the mobile phone is almost inevitable, so an effective mobile phone screen protection scheme becomes crucial for the design engineer.
Due to its multilayer glass structure, hard-screen OLEDs face the severe challenge of falling and broken screens. The high rate of falling and broken screens will cause a lot of repairs. Rogers has specially developed 4790-88 and 4790-79 formulas for hard-screen OLEDs, which can effectively buffer the impact caused by the moment of a drop, thereby reducing the occurrence of broken screens, significantly improving the consumer experience, and reducing the cost of repairing mobile phone manufacturers .
Because flexible OLEDs can achieve curved and even folding designs, their penetration rate in the high-end mobile phone market is growing rapidly. However, because it uses a polymer film as the carrier of the light-emitting layer, when the mobile phone is dropped, the risk of damage to it caused by the instantaneous impact from devices such as the FPC under the screen is high. In addition, the uneven stress distribution under the screen easily leads to visible deformation marks. Rogers Shockpad series foams are specially designed to deal with the problems of impact damage and deformation marks. While providing high-efficiency impact protection, they can effectively disperse stress. They are the best choice for flexible OLED screen underlay materials.
PORON® polyurethane OLED screen bottom liner material can absorb, disperse and isolate the impact energy when the OLED screen is impacted, so as to achieve the best protection for the display and prevent accidental damage.
