Title (EN) COVER FILM AND FLEXIBLE DISPLAY DEVICE
(FR) FILM DE COUVERTURE ET DISPOSITIF D'AFFICHAGE SOUPLE
(ZH) 覆盖膜及柔性显示装置
Abstract:
(EN) Provided is a cover film applicable to flexible display devices. The cover film comprises a light entrance surface (101) and a light exit surface (102). The light entrance surface (101) has multiple recessed portions. The recessed portion comprises an arch-shaped first portion (1031). By arranging multiple arch-shaped recessed portions at the cover film, bending of a flexible display device causes a less extent of change in an optical path, thereby preventing formation rainbow mura or moiré, and accordingly improving user experience. Moreover, since the recessed portions are arch-shaped structures having a certain curvature, the recessed portions can converge light to a certain extent, thereby increasing brightness of a visible region of the flexible display device.
(FR) L'invention concerne un film de couverture applicable à des dispositifs d'affichage flexibles. Le film de couverture comprend une surface d'entrée de lumière (101) et une surface de sortie de lumière (102). La surface d'entrée de lumière (101) comporte de multiples parties en creux. La partie en creux comprend une première partie en forme d'arc (1031). En agençant de multiples parties en creux en forme d'arc au niveau du film de couverture, la courbure d'un dispositif d'affichage souple provoque un changement moindre d'un trajet optique, ce qui évite la formation d'interférences en arc-en-ciel ou de moiré, et ainsi améliore l'expérience de l'utilisateur. De plus, comme les parties en creux sont des structures en forme d'arc ayant une certaine courbure, les parties en creux peuvent faire converger la lumière dans une certaine mesure, ce qui augmente la luminosité d'une région visible du dispositif d'affichage souple.
(ZH) 一种应用于柔性显示装置中的覆盖膜,覆盖膜包括入光面(101)和出光面(102),在入光面(101)上设置有多个凹部,凹部包括第一部分(1031),第一部分(1031)为拱形。通过在覆盖膜上设置多个具有拱形结构的凹部,使得柔性显示装置在折弯过程中,对光路改变较小,可避免出现彩虹纹或水波纹,从而提高了用户体验。另外,由于凹部为具有一定弧度的拱形结构,因此,这些凹部有一定的聚光作用,从而能够提升柔性显示装置的可视区的亮度。
