Title (EN) DOUBLE-SIDED DISPLAY PANEL AND DOUBLE-SIDED DISPLAY DEVICE
(FR) PANNEAU D'AFFICHAGE DOUBLE FACE ET DISPOSITIF D'AFFICHAGE DOUBLE FACE
(ZH) 双面显示面板以及双面显示装置
Abstract:
(EN) A double-sided display panel and a double-sided display device. The double-sided display panel comprises a first substrate (1), a second substrate (2), electrode pairs respectively disposed on the first substrate (1) and the second substrate (2), as well as a color display unit (3), an isolating reflection layer (5), and a black and white display unit (4) that are sequentially arranged between the first substrate (1) and the second substrate (2). The color display unit (3) comprises an electrochromic material; the black and white display unit (4) comprises an electrolyte, and black particles (42) and white particles (43) that have opposite electric charges and are dispersed in the electrolyte; the isolating reflection layer (5) can allow ions in the electrolyte to penetrate through, and reflect light; ions in the electrolyte can penetrate through the isolating reflection layer (5) under the action of the electrode pairs, such that the electrochromic material in the color display unit (3) gains or loses electrons to display color images, and the black particles (42) and the white particles (43) in the black and white display unit (4) are layered according to colors to display black and white images. The double-sided display panel has a simple structure; the two sides thereof do not interfere with each other in displaying and can achieve bistable displaying.
(FR) L'invention concerne un panneau d'affichage double face et un dispositif d'affichage double face. Le panneau d'affichage double face comprend un premier substrat (1), un second substrat (2), des paires d'électrodes respectivement disposées sur le premier substrat (1) et le second substrat (2), ainsi qu'une unité d'affichage en couleur (3), une couche de réflexion isolante (5), et une unité d'affichage en noir et blanc (4) qui sont séquentiellement agencées entre le premier substrat (1) et le second substrat (2). L'unité d'affichage en couleur (3) comprend un matériau électrochromique ; l'unité d'affichage en noir et blanc (4) comprend un électrolyte, et des particules noires (42) et des particules blanches (43) qui ont des charges électriques opposées et qui sont dispersées dans l'électrolyte ; la couche réfléchissante isolante (5) peut permettre à des ions dans l'électrolyte de la traverser, et de réfléchir la lumière ; des ions dans l'électrolyte peuvent pénétrer à travers la couche réfléchissante isolante (5) sous l'action de la paire d'électrodes, de telle sorte que le matériau électrochromique dans l'unité d'affichage en couleur (3) gagne ou perd des électrons pour afficher des images en couleur, et les particules noires (42) et les particules blanches (43) dans l'unité d'affichage noir et blanc (4) sont stratifiées selon les couleurs afin d'afficher des images en noir et blanc. Le panneau d'affichage double face a une structure simple ; les deux côtés de ce dernier n'interfèrent pas l'un avec l'autre en affichage, et peut parvenir à fournir un affichage bistable.
(ZH) 一种双面显示面板以及双面显示装置。该双面显示面板包括第一基板(1)、第二基板(2)、分别设置在所述第一基板(1)和所述第二基板(2)上的电极对、依次设置在第一基板(1)和所述第二基板(2)之间的彩色显示单元(3)、隔离反射层(5)和黑白显示单元(4),彩色显示单元(3)包括电致变色材料,黑白显示单元(4)包括电解液、分散于电解液中的带有相反电荷的黑色颗粒(42)和白色颗粒(43),隔离反射层(5)具有允许电解液中的离子透过以及对光进行反射的性质;电解液中的离子在电极对的作用下能透过隔离反射层(5),以使得述彩色显示单元(3)中的电致变色材料得电子或失电子显示彩色图案、以及黑白显示单元(4)中的黑色颗粒(42)和白色颗粒(43)按颜色分层显示黑白图案。该双面显示面板结构简单,双面显示互不影响,且都可以实现双稳态显示。
