Abstract
(EN)
Provided are a display panel and a preparation method therefor, and a display apparatus. A surface of an alignment layer is provided with a mesoporous guide film; mesopores that are uniformly distributed in the mesoporous guide film and have the same angle of tilt are used to cause liquid crystal molecules to tilt along the mesopores under the action of an applied voltage and stand in channels of the mesopores, so as to improve the problem of poor reliability being easily caused when the display apparatus realizes stable alignment, thereby reducing the manufacturing cost, increasing the product yield and shortening the processing time.
(FR)
L'invention concerne un écran d'affichage et son procédé de préparation, et un appareil d'affichage. Une surface d'une couche d'alignement est pourvue d'un film de guidage mésoporeux; des mésopores qui sont uniformément répartis dans le film de guidage mésoporeux et ont le même angle d'inclinaison, sont utilisés pour amener des molécules de cristaux liquides à s'incliner le long des mésopores sous l'action d'une tension appliquée et se tiennent dans des canaux des mésopores, de façon à améliorer le problème de faible fiabilité étant facilement provoqué lorsque l'appareil d'affichage réalise un alignement stable, ce qui permet de réduire le coût de fabrication, d'augmenter le rendement du produit et de raccourcir le temps de traitement.
