图 4是本发明实施例提供的屏幕区域化显示的显示区域示意图,如图 4 所示, LCD背光驱动控制器还可以分组形成两个到三个或者更多个 LCD背 光驱动组, 不同的 LCD背光驱动组对应不同的显示区域, 显示区域可以才艮 据屏幕的大小和分辨率而定, 优选情况下, 划分 2到 3个显示区域较为合 适。 例如, 我们通常用的 5英寸屏幕分辨率为 800*1280像素, 我们可以将 其划分成三个显示区域, 分别是 800*480, 800*320, 800*480分辨率的显 示屏。
图 5是本发明实施例提供的屏幕区域化显示的操作流程图, 如图 5所 示, 具体步骤如下:
步骤 501 : 终端应用屏幕区域化显示功能触发按键。
步骤 502: 主控芯片收到按键命令后, 启动屏幕区域化显示功能, 调用 应用场景, 控制 LCD背光驱动控制器。
步骤 503:主控芯片列出不同的应用场景及其对应的屏幕大小供用户选 择。 用户选择应用场景 1或 2或 3...或 n。
步骤 504: 根据用户选择输出需要显示的屏幕大小。如输出 800*480或 480*320或 800*1280。
概括的来说, 首先用户通过按键触发通知终端启动屏幕区域化显示功 能, 终端的 LCD背光驱动控制器分组使得屏幕能够进行区域化显示。 在节 电模式下,启动应用模式切换触发按键,驱动 LCD背光驱动控制器,使 LCD 背光只点亮特定应用场景下的屏幕, 从而实现终端节电。
图 6是本发明实施例提供的屏幕区域化显示的 LCD背光驱动灯结构图, 如图 6所示, LCD背光驱动控制器是靠 LCD背光灯实现的, LCD背光灯 通常情况放置在显示屏的最下边, LCD背光灯的个数是由屏幕的大小决定 的。 将 LCD背光灯进一步细化分解, 一块 LCD屏幕的 LCD背光灯分解为 2组或 3组 LCD背光灯或更多,分配不同的显示分辨率给不同的 LCD背光 灯点亮的区域, 每组独立控制, 实现单独控制点亮。 其中, 开关只是示意, 在实际应用中该开关可以是一个通用输入 /输出 ( GPIO: General Purpose Input Output )软控开关。
本发明实施例还提供一种计算机可读存储介质, 所述存储介质包括一 组计算机可执行指令, 所述指令用于执行本发明实施例所述的屏幕区域化 显示的方法。
综上所述, 本发明实施例具有以下技术效果: 能够通过将 LCD背光驱 动控制器分组化, 以及配合终端自身主控芯片的预置应用场景, 灵活设置 终端 LCD屏幕显示方式, 实现大屏省电显示, 提升用户体验。
