Title
(EN) DISPLAY PANEL AND PREPARATION METHOD THEREFOR
(FR) PANNEAU D’AFFICHAGE ET SON PROCÉDÉ DE PRÉPARATION
(ZH) 一种显示面板及其制备方法
Abstract
(EN)
Disclosed are a display panel and a preparation method therefor. The display panel comprises a substrate (1), a light-emitting layer (2), a first inorganic layer (31), a second inorganic layer (32), an organic layer (33) and a third inorganic layer (34). The preparation method for the display panel comprises a substrate (1) evaporation step (S1), a light-emitting layer (2) preparation step (S2), a first inorganic layer (31) preparation step (S3), a mask plate (20) mounting step (S4), a second inorganic layer (32) preparation step (S5), a mask plate (20) removal step (S6), an organic layer (33) preparation step (S7) and a third inorganic layer (34) preparation step (S8). By arranging a linear organic layer (33) in the second inorganic layer (32), the display panel is bendable at the position corresponding to the organic layer (33), and the second inorganic layer (32) on two sides of the organic layer (33) is not bendable; an area, corresponding to the organic layer (33), of the display panel is referred to as a bending area (100), and an area, corresponding to the second inorganic layer (32), of the display panel is referred to as a non-bending area (200); and not only can good bending performance of the bending area (100) be ensured, but water and oxygen resistance of the non-bending area (200) can also be improved, thereby prolonging the service life of the display panel.

La présente invention concerne un panneau d'affichage et son procédé de préparation. Le panneau d'affichage comprend un substrat (1), une couche électroluminescente (2), une première couche inorganique (31), une deuxième couche inorganique (32), une couche organique (33) et une troisième couche inorganique (34). Le procédé de préparation du panneau d'affichage comprend une étape d'évaporation (S1) de substrat (1), une étape de préparation (S2) de couche électroluminescente (2), une première étape de préparation (S3) de couche inorganique (31), une étape de montage (S4) de plaque de masque (20), une seconde étape de préparation (S5) de couche inorganique (32), une étape de retrait de plaque de masque (20), une étape de préparation (S7) de couche organique (33) et une troisième étape de préparation (S8) de couche inorganique (34). En disposant une couche organique linéaire (33) dans la seconde couche inorganique (32), le panneau d'affichage est pliable à la position correspondant à la couche organique (33), et la seconde couche inorganique (32) sur deux côtés de la couche organique (33) n'est pas pliable ; une zone, correspondant à la couche organique (33), du panneau d'affichage est désignée par une zone de flexion (100), et une zone, correspondant à la seconde couche inorganique (32), du panneau d'affichage est désignée par une zone de non flexion (200) ; et non seulement une bonne performance de flexion de la zone de flexion (100) peut être garantie, mais l'eau et la résistance à l'oxygène de la zone de non flexion (200) peuvent également être améliorées, ce qui permet de prolonger la durée de vie du panneau d'affichage.

一种显示面板及其制备方法,显示面板包括基板(1)、发光层(2)、第一无机层(31)、第二无机层(32)、有机层(33)以及第三无机层(34);显示面板的制备方法包括基板(1)蒸镀步骤(S1)、发光层(2)制备步骤(S2)、第一无机层(31)制备步骤(S3)、掩膜板(20)安装步骤(S4)、第二无机层(32)制备步骤(S5)、掩膜板(20)移除步骤(S6)、有机层(33)制备步骤(S7)以及第三无机层(34)制备步骤(S8);通过在第二无机层(32)中设置一直线形的有机层(33),使得显示面板在有机层(33)对应的位置是可弯折的,有机层(33)两侧的第二无机层(32)是不弯折的,进而使得显示面板与有机层(33)对应的区域被称为弯折区(100),显示面板与第二无机层(32)对应的区域被称为非弯折区(200),既可以保证弯折区(100)的弯折性能良好,又可以提高非弯折区(200)的阻水氧能力,延长显示面板的寿命。
