Abstract:
(EN) Provided are a method and device for generating a backlight control signal from backlight data in a liquid crystal display apparatus. The method comprises: configuring a plurality of backlight control cycles within a backlight data cycle of a current frame, respectively generating, according to a sum of weights of backlight data of the current frame and backlight data of preceding one or more frames, backlight control signals for several earlier backlight control cycles of the plurality of backlight control cycles, and generating, according to the backlight data of the current frame, backlight control signals for several later backlight control cycles of the plurality of backlight control cycles (S220).
(FR) La présente invention concerne un dispositif et un procédé destinés à générer un signal de commande de rétroéclairage à partir de données de rétroéclairage dans un appareil d'affichage à cristaux liquides. Le procédé consiste : à configurer une pluralité de cycles de commande de rétroéclairage dans un cycle de données de rétroéclairage d'une trame actuelle, à générer respectivement, conformément à une somme de poids de données de rétroéclairage de la trame actuelle et des données de rétroéclairage d'au moins une trame précédente, des signaux de commande de rétroéclairage pour plusieurs cycles de commande de rétroéclairage antérieurs de la pluralité de cycles de commande de rétroéclairage, et à générer, conformément aux données de rétroéclairage de la trame actuelle, des signaux de commande de rétroéclairage pour plusieurs cycles de commande de rétroéclairage ultérieurs de la pluralité de cycles de commande de rétroéclairage (S220).
(ZH) 一种用于液晶显示设备中由背光数据产生背光控制信号的方法及装置。当前帧背光数据周期内配置多个背光控制周期,分别基于当前帧背光数据与前一帧或前多帧背光数据的权重之和,生成多个背光控制周期中前若干个背光控制周期的背光控制信号,基于当前帧背光数据生成多个背光控制周期中后若干个背光控制周期的背光控制信号(S220)。
