Title (EN) GRAYSCALE COLOR ELECTRONIC PAPER
(FR) PAPIER ÉLECTRONIQUE COULEUR À ÉCHELLE DE GRIS
(ZH) 一种灰度彩色电子纸
Abstract:
(EN) A grayscale color electronic paper, each pixel structural unit of the electronic paper comprising a base color layer (2) and a grayscale adjusting layer (1), the base color layer (2) being able to display two or more colors, the colors displayed by the grayscale adjusting layer (1) corresponding one to one to the colors displayed by the base color layer (2), and the base color layer (2) and the grayscale adjusting layer (1) having respective driving structures. The base color layer (2) can display colors such as black, white, red, green, blue, cyan, magenta and yellow; and the grayscale adjusting layer (1) has multi-level gray scales, each level of gray scale having a steady state at a zero electric field. The electronic paper balances the degree of difficulty in manufacturing a driving source device and a display structure, reduces manufacturing costs, can achieve a stable display in multi-level gray scales, has a good color gamut range, and can be applied to more application fields.
(FR) Un papier électronique couleur à niveaux de gris, chaque unité structurelle de pixel du papier électronique comprenant une couche de couleur de base (2) et une couche d'ajustement d'échelle de gris (1), la couche de couleur de base (2) capable d'afficher au moins deux couleurs, les couleurs affichées par la couche d'ajustement d'échelle de gris (1) correspondant à l'une des couleurs affichées par la couche de couleur de base (2), et la couche de couleur de base (2) et la couche d'ajustement d'échelle de gris (1) ayant des structures de commande respectives. La couche de couleur de base (2) peut afficher des couleurs telles que le noir, le blanc, le rouge, le vert, le bleu, le cyan, le magenta et le jaune; et la couche d'ajustement d'échelle de gris (1) a des échelles de gris à niveaux multiples, chaque niveau d'échelle de gris ayant un état stable au niveau d'un champ électrique nul. Le papier électronique équilibre le degré de difficulté de fabrication d'un dispositif source de commande et d'une structure d'affichage, réduit les coûts de fabrication, peut réaliser un affichage stable dans des échelles de gris à niveaux multiples, présente une bonne plage de gamme de couleurs, et peut être appliquée à plusieurs champs d'applications.
(ZH) 一种灰度彩色电子纸,该电子纸的每个像素结构单元包括基础颜色层(2)和灰度调节层(1),所述基础颜色层(2)能显示两种或两种以上颜色,所述灰度调节层(1)的显示颜色和所述基础颜色层(2)一一对应,所述基础颜色层(2)和所述灰度调节层(1)具有各自的驱动结构。所述基础颜色层(2)可以显示黑、白、红、绿、蓝、青、品红和黄等颜色;所述灰度调节层(1)具有多级灰度,且在每级灰度都具有零电场下的稳定状态。该电子纸平衡了驱动源器件和显示结构的制作难度,降低制作成本,能实现稳定的多级灰度显示,且具有良好的色域范围,能适应更多应用领域。
