Title (EN) SCAN DRIVING CIRCUIT AND DISPLAY APPARATUS
(FR) CIRCUIT DE COMMANDE DE BALAYAGE ET APPAREIL D'AFFICHAGE
(ZH) 扫描驱动电路及显示装置
Abstract:
(EN) A scan driving circuit and a display apparatus. The scan driving circuit comprises several cascaded scan driving units (1), each unit comprising: an input circuit (10) which generates a pull-up control signal (H(n)) and a pull-down control signal (L(n)); a latch circuit (20) which performs pull-up and pull-down on a pull-up control signal point (Q(n)); a processing circuit (30) which generates a present level scan driving signal (Gate(n)); a buffer circuit (40) which drives an output of the present level scan driving signal (Gate(n)); a reset circuit (50) which clears the pull-up control signal point (Q(n)). The scan driving circuit thus increases display apparatus driving flexibility, reduces driving power consumption, and facilitates narrow frame design.
(FR) La présente invention concerne un circuit de commande de balayage et un appareil d’affichage. Le circuit de commande de balayage comprend plusieurs unités de commande de balayage en cascade (1), chaque unité comprenant : un circuit d'entrée (10) qui génère un signal de commande d'excursion haute (H (n)) et un signal de commande d'excursion basse (L (n)) ; un circuit de verrouillage (20) qui effectue une excursion haute et une excursion basse sur un point de signal de commande d'excursion haute (Q (n)) ; un circuit de traitement (30) qui génère un signal de commande de balayage de niveau présent (Grille (n)) ; un circuit tampon (40) qui commande une sortie du signal de commande de balayage de niveau présent (Grille (n)) ; un circuit de réinitialisation (50) qui efface le point de signal de commande d'excursion haute (Q (n)). Le circuit de commande de balayage augmente ainsi la flexibilité de commande de l'appareil d'affichage, réduit la consommation d'énergie de commande, et facilite la conception de cadre étroit.
(ZH) 一种扫描驱动电路及显示装置。扫描驱动电路包括若干级联的扫描驱动单元(1),其包括输入电路(10)产生上拉控制信号(H(n))及下拉控制信号(L(n));锁存电路(20)对上拉控制信号点(Q(n))进行上拉及下拉;处理电路(30)产生本级扫描驱动信号(Gate(n));缓存电路(40)驱动本级扫描驱动信号(Gate(n))的输出;复位电路(50)对上拉控制信号点(Q(n))进行清零,以此提高显示装置驱动的灵活性,而且降低了驱动功耗且利于窄边框设计。
