Title (EN) DISPLAY SCREEN CONTROL METHOD AND TERMINAL
(FR) PROCÉDÉ ET TERMINAL DE COMMANDE D'ÉCRAN D'AFFICHAGE
(ZH) 显示屏控制方法及终端
Abstract:
(EN) Provided in the present application are a display screen control method and terminal. detecting whether a terminal meets a low power consumption operation condition, wherein a display screen of the terminal is an OLED display screen, and each pixel unit of the OLED display screen at least comprises a red sub-pixel, a blue sub-pixel, and a green sub-pixel; upon detecting that the terminal meets the low power consumption operation condition, reducing the frequency of any one or two of a red sub-pixel drive signal, green sub-pixel drive signal, and blue sub-pixel drive signal. By reducing the frequency of any one or two of the drive signals, the present invention lowers function performance of a display drive chip, and reduces power consumption accordingly.
(FR) L'invention concerne un procédé et un terminal de commande d'écran d'affichage. L’invention concerne un procédé consistant à : détecter si un terminal répond à une condition de fonctionnement à faible consommation d'énergie, un écran d'affichage du terminal étant un écran d'affichage OLED, et chaque unité de pixel de l'écran d'affichage OLED comprenant au moins un sous-pixel rouge, un sous-pixel bleu et un sous-pixel vert ; lorsqu'il est détecté que le terminal répond à la condition de fonctionnement à faible consommation d'énergie, réduire la fréquence d'un ou de deux signaux quelconques parmi un signal de commande de sous-pixel rouge, un signal de commande de sous-pixel vert et un signal de commande de sous-pixel bleu. En réduisant la fréquence d’un ou de deux signaux quelconques parmi les signaux de commande, l’invention diminue les performances de fonctionnement d'une puce de commande d'affichage et réduit la consommation d'énergie en conséquence.
(ZH) 本申请提供了一种显示屏控制方法及终端。监测终端是否满足低功耗运行条件,其中,所述终端的显示屏为有机发光显示屏,所述有机发光显示屏的每个像素单元至少包括一个红色子像素、一个蓝色子像素和一个绿色子像素。监测到所述终端满足所述低功耗运行条件,降低红色子像素的驱动信号、绿色子像素的驱动信号和蓝色子像素的驱动信号中的任意一个或任意两个的频率。通过降低任意一个或任意两个驱动信号的频率,可以降低显示驱动芯片的功能,因此,能够节省功耗。
