Abstract:
(EN) A touch display screen (100) and a preparation method, display apparatus and drive method therefor. The touch display screen (100) comprises: a first substrate (101) and a second substrate (102) arranged opposite each other; a first electrode (103) and a second electrode (140) arranged between the first substrate (101) and the second substrate (102) and capable of generating a horizontal electric field when in a powered-up state; a liquid crystal (106) filled between the first substrate (101) and the second substrate (102); and a touch sensing electrode (107) provided at an outer side or an inner side of the second substrate (102). The liquid crystal (106) comprises a nematic phase liquid crystal and a long-chain compound (105) dispersed in the nematic phase liquid crystal and enabling the nematic phase liquid crystal to be in a scattered state. The touch display screen (100) is based on an optical waveguide structure and improves the transmittance of light rays; and conditions for total reflection of light rays are destroyed by the long-chain compound (105), so that liquid crystal molecules are in a scattered state, thereby realizing a display function.
(FR) Un écran tactile (100) et un procédé de préparation, un appareil d'affichage et un procédé de commande associé. L'écran d'affichage tactile (100) comprend : un premier substrat (101) et un second substrat (102) disposés en regard l'un de l'autre; une première électrode (103) et une seconde électrode (140) disposées entre le premier substrat (101) et le second substrat (102) et capable de générer un champ électrique horizontal lorsqu'il est dans un état activé; un cristal liquide (106) rempli entre le premier substrat (101) et le second substrat (102); et une électrode de détection tactile (107) disposée au niveau d'un côté externe ou d'un côté interne du second substrat (102). Le cristal liquide (106) comprend un cristal liquide en phase nématique et un composé à chaîne longue (105) dispersé dans le cristal liquide en phase nématique et permettant au cristal liquide en phase nématique d'être dans un état dispersé. L'écran tactile (100) est basé sur une structure de guide d'ondes optique et améliore la transmittance des rayons lumineux; et les conditions de réflexion totale des rayons lumineux sont détruites par le composé à longue chaîne (105), de sorte que les molécules de cristaux liquides sont dans un état dispersé, réalisant ainsi une fonction d'affichage.
(ZH) 一种触摸显示屏(100)及其制备方法、显示装置和驱动方法,触摸显示屏(100)包括:相对设置的第一基板(101)和第二基板(102);设置在第一基板(101)和第二基板(102)之间,且在加电状态下可产生水平电场的第一电极(103)和第二电极(104);填充在第一基板(101)和第二基板(102)之间的液晶(106);设置在第二基板(102)外侧或内侧的触摸感应电极(107)。液晶(106)包括向列相液晶以及分散在向列相液晶中的可以使向列相液晶形成散射态的长链化合物(105)。触摸显示屏(100)以光波导结构为基础,提高了光线的透过率;通过长链化合物(105)破坏光线全反射的条件使液晶分子呈散射态,由此实现显示功能。
