Description

液晶显示器和电子设备
【技术领域】
本发明涉及液晶技术领域，特别是涉及一种液晶显示器和电子设备。
【背景技术】
随着技术的发展，液晶显示器已经逐渐成为各种电子设备中，其具有高分辨率彩色屏幕的显示面板。而随着液晶显示面板技术的发展进步，人们对液晶显示面板的显示品质、外观设计、样式、低成本和高穿透率等提出了更高的要求。
而为迎合消费者的需求，目前电子设备设置有多种样式的屏幕，如单屏幕或双屏幕。对于双屏幕的电子设备，其包括主屏幕和副屏幕，主屏幕和副屏幕是互相独立的，其能够单独完成各自的功能，并各自显示不同的数据，提高了用户的体验。然而，在目前的双屏幕电子设备中，在主屏幕和副屏幕的驱动信号控制过程中，都是统一发送驱动信号给主屏幕和副屏幕，即发送驱动信号给主屏幕的同时也发送驱动信号给副屏幕，这也不利于控制双屏幕的驱动信号，容易加大了电子设备的功耗。
综上所述，有必要提供一种液晶显示器和电子设备以解决上述问题。
【发明内容】
本发明主要解决的技术问题是提供一种液晶显示器和电子设备，能够将主屏幕和副屏幕的驱动信号分开控制，有效降低电子设备的功耗。

【附图说明】
图1是本发明电子设备的结构示意图；
图2是本发明液晶显示器的结构示意图。
【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
本发明公开一种电子设备，如图1和图2所示，该电子设备包括液晶显示器，液晶显示器包括主屏幕11、副屏幕12、驱动电路13、受控开关14、电源15、副屏幕扫描电路16和主屏幕扫描电路17。在本实施例中，电子设备优选为手机、平板电脑、IPAD、电视机。
主屏幕11包括主屏幕阵列基板111，主屏幕阵列基板111设置有第一供电信号输入端1111和第二供电信号输入端1112。
副屏幕12包括副屏幕阵列基板121，副屏幕阵列基板121设置有第一供电信号输入端1211和第二供电信号输入端1212。
电源15直接提供供电信号至主屏幕阵列基板121。具体地，电源15设置有第一供电信号输出端151和第二供电信号输出端152，第一供电信号输出端151与主屏幕阵列基板111的第一供电信号输入端1111连接，第二供电信号输出端152与主屏幕阵列基板111的第二供电信号输入端1112连接。在本实施例中，第一供电信号输出端151输出第一供电信号，第二供电输出端152输出第二供电信号，第一供电信号为高电平，第二供电信号为低电平。
电源15通过受控开关13提供供电信号至副屏幕阵列基板121。具体地，受控开关13包括第一受控开关T1和第二受控开关T2，第一受控开关T1包括第一受控端133、第一连接端131和第二连接端132，第二受控开关T2包括第二受控端136、第三连接端134和第四连接端135。第一供电信号输出端151与第一连接端131连接，第二供电信号输出端152与第三连接端134连接。第二连接端132与副屏幕阵列基板121的第一供电信号输入端1211连接，第四连接端135与副屏幕阵列基板121的第二供电信号输入端1212连接，第一受控端133与第二受控端136连接。
在本实施例中，第一受控开关T1和第二受控开关T2均为NMOS管，第一受控开关T1的第一连接端131和第二受控开关T2的第三连接端134为NMOS管的源极，第一受控开关T1的第二连接端132和第二受控开关T2的第四连接端135为NMOS管的漏极，第一受控开关T1的第一受控端133和第二受控开关T2的第二受控端136为NMOS管的栅极。
在其他实施例中，第一受控开关T1和第二受控开关T2均为NPN型三极管，第一受控开关T1的第一连接端131和第二受控开关T2的第三连接端134为NPN型三极管的发射极，第一受控开关T1的第二连接端132和第二受控开关T2的第四连接端135为NPN型三极管的集电极，第一受控开关T1的第一受控端133和第二受控开关T2的第二受控端136为NPN型三极管的基极。
驱动电路14与受控开关13的第一受控端133连接，用于提供第一控制信号或第二控制信号至受控开关13。在驱动电路14提供第一控制信号至受控开关13时，第一受控开关T1和第二受控开关T2闭合，电源15与副屏幕阵列基板121连通，副屏幕阵列基板121获取到供电信号。在驱动电路14提供第二控制信号至受控开关13时，第一受控开关T1和第二受控开关T2断开，电源15与副屏幕阵列基板121不连通，副屏幕阵列基板121不能获取供电信号。
在本实施例中，驱动电路14还用于提供第一触发信号至副屏幕扫描电路16，副屏幕扫描电路16用于扫描副屏幕阵列基板121。具体地，在驱动电路14提供第一控制信号至受控开关13，且提供第一触发信号至副屏幕扫描电路16时，副屏幕扫描电路16响应第一触发电路扫描副屏幕阵列基板121，以令副屏幕12进行动态显示。在驱动电路14提供第一控制信号至受控开关13，且停止提供第一触发信号至副屏幕扫描电路16时，副屏幕扫描电路16停止扫描副屏幕阵列基板121，以令副屏幕12进行静态显示。其中，动态显示和静态显示均为亮态显示，动态显示指屏幕中的画面是动态的，静态显示指屏幕中的画面是静态不动的。
应理解，在驱动电路14停止提供第一控制信号至受控开关13时，第一受控开关T1和第二受控开关T2均断开，电源15无法向副屏幕阵列基板121提供供电信号，此时的副屏幕12不工作，为暗态显示状态。
在本实施例中，驱动电路14还用于提供第二触发信号至主屏幕扫描电路17，主屏幕扫描电路17用于扫描主屏幕阵列基板111。具体地，在驱动电路14提供第二触发信号至主屏幕扫描电路17，主屏幕扫描电路17响应第二触发信号扫描主屏幕阵列基板111，以令主屏幕11进行动态显示。主屏幕11和副屏幕12的动态显示与常规的液晶显示器工作原理一样。
在本实施例中，副屏幕阵列基板121采用像素内嵌存储器设计，在副屏幕12进行静态显示时，像素内嵌存储器能够锁住副屏幕12的画面，让副屏幕12长期处于同一画面，从而使得副屏幕12形成静态显示。静态显示时不需要进行信号刷新，即不需要驱动电路14提供第一控制信号至受控开关13，副屏幕12在静态显示的功耗是动态显示的功耗的十分之一，因此副屏幕12在显示一些诸如钟表这种静态画面的时候功耗会非常低。
综上，本发明的液晶显示器包括主屏幕、副屏幕、驱动电路、受控开关以及电源，副屏幕包括副屏幕阵列基板，主屏幕包括主屏幕阵列基板，电源直接提供供电信号至主屏幕阵列基板，并通过受控开关提供供电信号至副屏幕阵列基板，其中：驱动电路提供第一控制信号至受控开关使得受控开关闭合以令副屏幕阵列基板获取到供电信号，或提供第二控制信号至受控开关使得受控开关断开以令副屏幕阵列基板不能获取供电信号。本发明还公开一种电子设备。通过上述方式，本发明能够将主屏幕和副屏幕的驱动信号分开控制，有效降低电子设备的功耗。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
