Abstract:
(EN) A light filtering structure, a display substrate, a display panel and a display device are provided. The light filtering structure (111) comprises a first refractive index matching layer (1111), a waveguide layer (1112), a second refractive index matching layer (1113) and a grating layer (1114) that are stacked with one another. The waveguide layer (1112) is located between the first refractive index matching layer (1111) and the second refractive index matching layer (1113). The second refractive index matching layer (1113) is located between the waveguide layer (1112) and the grating layer (1114). Refractive indices of the first refractive index matching layer (1111) and the second refractive index matching layer (1113) are both less than a refractive index of the waveguide layer (1112).
(FR) La présente invention concerne une structure de filtrage de lumière, un substrat d’affichage, un panneau d’affichage et un dispositif d’affichage. La structure de filtrage de lumière (111) comprend une première couche d’adaptation d’indice de réfraction (1111), une couche de guide d’ondes (1112), une deuxième couche d’adaptation d’indice de réfraction (1113) et une couche de réseau (1114) qui sont empilées les unes sur les autres. La couche de guide d’ondes (1112) est située entre la première couche d’adaptation d’indice de réfraction (1111) et la deuxième couche d’adaptation d’indice de réfraction (1113). La deuxième couche d’adaptation d’indice de réfraction (1113) est située entre la couche de guide d’ondes (1112) et la couche de réseau (1114). Les indices de réfraction de la première couche d’adaptation d’indice de réfraction (1111) et de la deuxième couche d’adaptation d’indice de réfraction (1113) sont tous deux inférieurs à un indice de réfraction de la couche de guide d’ondes (1112).
(ZH) 一种滤光结构、显示基板、显示面板及显示装置。该滤光结构(111)包括层叠设置的第一折射率匹配层(1111)、波导层(1112)、第二折射率匹配层(1113)及光栅层(1114),波导层(1112)位于第一折射率匹配层(1111)与第二折射率匹配层(1113)之间,第二折射率匹配层(1113)位于波导层(1112)与光栅层(1114)之间,第一折射率匹配层(1111)及第二折射率匹配层(1113)的折射率均小于波导层(1112)的折射率。
