附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还 可以根据这些附图获得其他的附图。
图1为本发明实施例一提供的背板控制架构示意图；
图2为本发明实施例一提供的背板模组结构图；
图3为本发明实施例一提供的盖窗显示设备结构图；
图4为本发明实施例二提供的背板控制架构示意图；
图5为本发明实施例三提供的背板控制架构示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1为本发明实施例一提供的背板控制架构示意图，如图所示，背光控制架构10包括光敏传感器102、控制器104、驱动芯片106及LED灯条108。光敏传感器102通过感受环境光强弱将光信号转化为电信号，并将电信号发送给控制器104。控制器104包括判断单元1042与控制单元1044，判断单元1042接收光敏传感器102发送的电信号后，对信号进行处理匹配，判断设备所处的工作环境和工作状态，并通过控制单元1044向驱动芯片106发送指令。驱动芯片106包括第一驱动单元1062、第二驱动单元1064、第一驱动开关1066及第二驱动开关1068，结合图3，屏幕翻盖3打开时，光敏传感器102感受到的环境光较强，判断单元1042判断设备处于工作状态，控制单元1044向驱动芯片106发送指令，闭合第一驱动开关1066，断开第二驱动开关1068，仅启动第一驱动单元1062；屏幕翻盖3合上时，屏幕翻盖3遮挡光敏传感器102，光敏传感器102感受到的环境光较弱，判断单元1042判断设备处于待机状态，控制单元1044向驱动芯片106发送指令，闭合第二驱动开关1068，断开第一驱动开关1066，仅启动第一驱动单元1064。LED灯条108包括多个依次相邻排布的背光灯1082，其中部分LED背光灯1082组合成第一窗口灯组1080，一种实施方式中，第一窗口灯组1080位于LED灯条108的一端，当然，第一窗口灯组1080也可以位于LED灯条108的其他任意位置。LED灯条108的 全部背光灯1082均通过第一通道132连接至第一驱动单元1062，第一窗口灯组1080的背光灯1082均通过第二通道134连接至第二驱动单元1064，第一通道132与第二通道134为导线组成的实现电学器件之间电连接的介质。
结合图2，若启动第一驱动单元1062，LED灯条108工作发光，光源通过导光片16、反射片18、扩散片14及棱镜片12后形成背光源100，背光源100为面光源，并且背光源100的全部区域被点亮；若启动第二驱动单元1064，第一窗口灯组1080工作发光，光源通过导光片16、反射片18、扩散片14及棱镜片12后仅点亮背光源100的第一盖窗显示区域110。
第一驱动单元1062与第二驱动单元1064分别控制完整的LED灯条108与LED灯条108的部分背光灯1082组成的第一窗口灯组1080的发光情况，从而改变背光源100的发光区域。此设计使显示设备可判断工作环境并根据工作要求对背光源100的发光区域进行控制选择，背光模组10灵活的适应各种工作模式要求，避免不必要的背光源100产生，节省电源消耗，达到降低设备功耗的目的。
图3为本发明实施例一提供的盖窗显示设备结构图，盖窗显示设备包括背光模组1、显示屏2及屏幕翻盖3，其中屏幕翻盖3设有盖窗32。结合图1与图2，背光模组1判断翻盖显示设备的工作状态并按照显示需求驱动背光模组1产生背光光源100，背光光源100穿过显示屏2并在显示屏2的显示区域上显示需要的图像。翻盖显示设备具有两个工作状态，即屏幕翻盖3打开的使用状态与屏幕翻盖3合上的待机状态。当屏幕翻盖3打开时，背光源100的全部区域发光，背光源100穿过显示屏2并在显示屏2全屏显示图像；当翻盖合上时，背光源100的第一盖窗显示区域110发光，背光源100穿过显示屏2并在显示屏2的对应窗盖的区域显示图像。一种实施方式中，背光控制架构10设有屏幕驱动芯片，屏幕驱动芯片控制盖窗显示设备分别处于工作状态与待机状态时显示屏2显示的图像内容。
盖窗显示设备通过屏幕翻盖3的打开与闭合将显示设备的工作状态与待机状态区分，工作状态下显示屏2全屏显示，满足使用需求；待机状态下显示屏2仅显示对应的窗盖32的窗口显示区域，避免多余电源的损耗，保证观影视效的同时又达到降低手机功耗的目的。
图4为本发明实施例二提供的背板模组原理图，如图所示，与实施例一的区别在于，背光源15具有多个盖窗显示区域。一种实施方式中，背光源100具有第一盖窗显示区域110与第二盖窗显示区域120，第一盖窗显示区域110由第一窗口灯组1080提供的光源点亮，第二盖窗显示区域120由第二窗口灯组1280提供的光源点亮，第一窗口灯组1080与第二窗口灯组1280均由第二驱动单元1064控制并同时开关。一种实施方式中，第一窗口灯组1080与第二窗口灯组1280不具有相同的背光灯1082，且第一窗口灯组1080与第二窗口灯组1280的位置不相邻，由此产生的第一盖窗显示区域110与第二盖窗显示区域120不相交且不相邻，当然，第一盖窗显示区域110与第二盖窗显示区域120可以相邻也可以相交。
本实施例提供的背光模组1同样具有适应各种工作环境且节省电源消耗的优点，同时本实施例提供的背光模组1对应装配的显示屏2可以更灵活的显示更丰富的图像，降低设备功耗的同时得到更好的用户体验。
图5为本发明实施例三提供的背板模组原理图，如图所示，与实施例二的区别在于，各窗口灯组由一个对应的驱动单元单独控制。一种实施方式中，驱动芯片106包括第二驱动单元1064与第三驱动单元1065，LED灯条108包括第一窗口灯组1080与第二窗口灯组1280，第二驱动单元1064单独控制第一窗口灯组1080，第三驱动单元1065单独控制第二窗口灯组1280，第一窗口灯组1080与第二窗口灯组1280可以单独开关，即第一盖窗显示区域110与第二盖窗显示区域120可以单独点亮。
本实施例三提供的背板模组相较于实施例二提供的背板模组具有更高的灵活性，能够提高显示效果的同时有效的降低功耗。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易的想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
