Title (EN) SWITCH UNIT, DISPLAY PANEL, MANUFACTURING METHOD THEREOF, AND DISPLAY APPARATUS
(FR) UNITÉ DE COMMUTATION, PANNEAU D’AFFICHAGE, PROCÉDÉ DE FABRICATION ASSOCIÉ, ET APPAREIL D’AFFICHAGE
Abstract:
(EN) A display panel may include a plurality of switch units. Each of the plurality of the switch units include a first electrode (1); a second electrode (2); a third electrode (3); a fourth electrode (4) opposite to the first electrode (1); a piezoelectric material layer (5) between the first electrode (1) and the fourth electrode (4); a connecting electrode (6) above the fourth electrode (4) and electrically insulated from the fourth electrode (4); and a driving transistor comprising a driving gate. The driving gate may be the third electrode (3). An orthogonal projection of the second electrode (2) and an orthogonal projection of the third electrode (3) on a plane of the connecting electrode (6) may overlap the connecting electrode (6) respectively.
(FR) Panneau d'affichage pouvant comprendre une pluralité d'unités de commutation. Chaque unité de commutation comprend : une première électrode (1); une deuxième électrode (2); une troisième électrode (3); une quatrième électrode (4) en regard de la première électrode (1); une couche de matériau piézoélectrique (5) située entre la première électrode (1) et la quatrième électrode (4); une électrode de raccordement (6) disposée au-dessus de la quatrième électrode (4) et isolée électriquement de cette dernière (4); et un transistor d'attaque comprenant une grille d'excitation. La grille d'excitation peut être la troisième électrode (3). Une projection orthogonale de la deuxième électrode (2) et une projection orthogonale de la troisième électrode (3) sur un plan de l'électrode de raccordement (6) peuvent chevaucher respectivement l'électrode de raccordement (6).
