Title (EN) DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
(FR) PANNEAU D'AFFICHAGE ET SON PROCEDE DE FABRICATION, ET DISPOSITIF D'AFFICHAGE
(ZH) 显示面板及其制作方法、显示装置
Abstract:
(EN) A display panel and a manufacturing method therefor, and a display device. The display panel comprises a plurality of display units (1), and each of the display units (1) comprises a first substrate (10) and a second substrate (20) oppositely arranged. The first substrate (10) comprises a first base substrate (101), and a first electrode (102), an electrostrictive layer (103) and a reflection groove (104) arranged thereon. The second substrate (20) comprises a second base substrate (201), and a second electrode (202) and a reflection cavity (203) arranged thereon. A support (30) is arranged between the first base substrate (101) and the second base substrate (201) to keep the distance therebetween unchanged. The reflection groove (104) has a recessed portion (1041). The reflection cavity (203) has a protruding portion (2031), and the surface of the recessed portion (1041) of the reflection groove (104) matches the surface of the protruding portion (2031) of the reflection cavity (203). The first electrode (102) and the second electrode (202) are configured to form an electric field, and the electrostrictive layer (103) can be deformed under the action of the electric fields in the direction perpendicular to the first base substrate (101), so that the recessed portion (1041) of the reflection groove (104) and the protruding portion (2031) of the reflection cavity (203) can be switched between the mode where a gap (431) is formed therebetween and the mode where the surfaces of both are closely attached.
(FR) L’invention concerne un panneau d’affichage et son procédé de fabrication, et un dispositif d’affichage. Le panneau d'affichage comprend une pluralité d'unités d'affichage (1), et chacune des unités d'affichage (1) comprend un premier substrat (10) et un second substrat (20) agencés de manière opposée. Le premier substrat (10) comprend un premier substrat de base (101), et une première électrode (102), une couche électrostrictive (103) et une rainure de réflexion (104) disposée sur celui-ci. Le second substrat (20) comprend un second substrat de base (201), et une seconde électrode (202) et une cavité de réflexion (203) disposés sur celui-ci. Un support (30) est disposé entre le premier substrat de base (101) et le second substrat de base (201) pour maintenir la distance entre eux. La rainure de réflexion (104) a une partie évidée (1041). La cavité de réflexion (203) a une partie saillante (2031), et la surface de la partie évidée (1041) de la rainure de réflexion (104) correspond à la surface de la partie saillante (2031) de la cavité de réflexion (203). La première électrode (102) et la seconde électrode (202) sont configurées pour former un champ électrique, et la couche électrostrictive (103) peut être déformé sous l'action des champs électriques dans la direction perpendiculaire au premier substrat de base (101), de sorte que la partie évidée (1041) de la rainure de réflexion (104) et la partie en saillie (2031) de la cavité de réflexion (203) peut être commuté entre le mode dans lequel un espace (431) est formé entre eux et le mode dans lequel les surfaces des deux sont étroitement fixées.
(ZH) 提供一种显示面板及其制作方法、显示装置。该显示面板包括多个显示单元(1),每个显示单元(1)包括彼此相对设置的第一基板(10)和第二基板(20)。第一基板(10)包括第一衬底基板(101)以及设置在其上的第一电极(102)、电致伸缩层(103)和反射凹槽(104)。第二基板(20)包括第二衬底基板(201)以及设置在其上的第二电极(202)和反射腔体(203)。在第一衬底基板(101)和第二衬底基板(201)之间设置支撑物(30),以使得其间的距离保持不变。反射凹槽(104)具有凹陷部(1041),反射腔体(203)具有凸起部(2031),反射凹槽(104)的凹陷部(1041)的表面和反射腔体(203)的凸起部(2031)的表面相匹配。第一电极(102)和第二电极(202)被配置来形成电场,电致伸缩层(103)在电场的作用下可在垂直于第一衬底基板(101)的方向上发生变形,使得反射凹槽(104)的凹陷部(1041)和反射腔体(203)的凸起部(2031)可在其间形成有间隙(431)和两者表面紧密贴合之间进行转换。
