Abstract
(EN) A display panel (100). By means of changing a routing mode of a sub-pixel data line, a non-display area (102) of a first sub-pixel (110) is provided with a first data line (112), and the first data line (112) is provided with a branch in a display area (101). In addition, the display area (101) of the first sub-pixel (110) is further provided with a second data line (1124). By means of configuring opposite signals for the first data line (112) and the second data line (1124), coupling voltages of the signals of the two data lines for the sub-pixel can counteract one another, thereby solving the problem of vertical crosstalk of an ultra-narrow frame.
(FR) L'invention concerne un panneau d'affichage (100). Grâce au changement d'un mode de routage d'une ligne de données de sous-pixel, une zone de non-affichage (102) d'un premier sous-pixel (110) est dotée d'une première ligne de données (112), et la première ligne de données (112) est dotée d'une ramification dans une zone d'affichage (101). De plus, la zone d'affichage (101) du premier sous-pixel (110) est en outre pourvue d'une seconde ligne de données (1124). Grâce à la configuration de signaux opposés pour la première ligne de données (112) et la seconde ligne de données (1124), les tensions de couplage des signaux des deux lignes de données pour le sous-pixel peuvent s'opposer l'une à l'autre, ce qui permet de résoudre le problème de la diaphonie verticale dans un cadre ultra étroit.
(ZH) 一种显示面板（100），通过改变子像素数据线走线方式，使第一子像素（110）的非显示区（102）具有第一数据线（112），第一数据线（112）在显示区（101）设置分支，另外，第一子像素（110）的显示区（101）还设有第二数据线（1124），通过将第一数据线（112）与第二数据线（1124）设置相反的信号，使两个数据线信号对子像素的耦合电压可以相互抵消，改善超窄边框垂直串扰的问题。
