本发明提供一种大小可变的显示屏幕、 移动终端及其实现方法, 为使本发明的目的、 技术方案及效果更加清楚、 明确, 以下对本发明 进一步详细说明。应当理解, 此处所描述的具体实施例仅仅用以解释 本发明, 并不用于限定本发明。
请参阅图 1, 其为本发明的大小可变的显示屏幕的结构框图, 如 图所示, 所述显示屏幕包括: 主显示屏幕 100和折叠屏幕 200; 其中, 所述主显示屏幕 100和折叠屏幕 200之间转动连接,所述主显示屏幕 100和折叠屏幕 200之间设置有用于感应折叠屏幕状态的传感器 300。
本发明的关键是通过折叠屏幕的折叠和展开来改变屏幕显示的 大小: 通过展开折叠屏幕使其显示区域变大, 其显示效果等同于平板 电脑的显示效果; 而通过折叠所述折叠屏幕使显示区域变小, 其显示 效果等同于智能手机的显示效果, 方便携带和拨打电话及发短信等。
其中, 所述传感器 300可以是压接传感器或接近传感器。压接传 感器是通过主屏和折叠屏打开或关闭两个状态使压接传感器形态变 化, 压接传感器可等效成开关, 当折叠屏幕 200展开时, 根据主显示 屏幕 100和折叠屏幕 200之间的挤压的力量使其之间的压接传感器闭 合导通, 这样控制芯片会检测到导通的传感器, 并判定折叠屏幕 200 已展开, 这样控制芯片启动折叠屏幕 200的显示。 同理, 当折叠屏幕 200闭合(也称折叠)时, 主显示屏幕 100和折叠屏幕 200之间的挤 压力消失, 使其之间的压接传感器 300由闭合导通而变为断开, 这样 控制芯片会检测到断开的传感器 300, 并判定折叠屏幕 200已闭合, 控制芯片就关闭折叠屏幕 200的显示。而接近传感器的实现主要是根 据霍尔效应原理来实现的,通过使用开关型霍尔传感器来传感折叠屏 的展开与闭合。 因其原理为现有技术, 这里就不多做赞述了。 具体来说, 请一并参阅图 2, 所述显示屏幕包括: 一个主显示屏 幕 100和两个折叠屏幕 200, 两个折叠屏幕 200分别位于主显示屏幕 100的两侧。所述主显示屏幕 100和折叠屏幕 200之间设置有转轴 310 和柔性电缆 320: 转轴 310用于折叠屏幕进行折叠和展开时的转动; 柔性电缆 320连接在主显示屏幕 100和折叠屏幕 200之间。在本实施 例中, 所述传感器 300为压接传感器 (也称挤压传感器), 其位于主 显示屏幕 100上与折叠屏幕 200相接的一侧。当折叠屏幕 200展开时, 如图 3所示, 折叠屏幕 200会挤压传感器 300, 令传感器 300感知到 所述折叠屏幕 200 的状态变化, 从而对显示屏幕的显示状态进行更 新:令与相应传感器 300相连的折叠屏幕 200和主显示屏幕 100共同 进行显示。 当折叠屏幕收起来时(也称处于折叠状态, 如图 4所示), 折叠屏幕和主显示屏幕 100之间的传感器由挤压状态变为弹起状态, 从而对显示屏幕的显示状态进行更新:令主显示屏幕 100单独进行显 示。
本发明还提供了一种移动终端,其包括上述的大小可变的显示屏 幕和控制芯片; 所述传感器和控制芯片相连。 所述移动终端在通常状 态下显示屏幕是折叠在一起的 (即折叠屏幕处于折叠状态), 这样便 于携带和打电话, 如同智能手机一样; 当需要大屏幕显示时, 如看电 影、 玩游戏等, 把折叠屏幕展开, 这样显示屏变得很大, 如同平板电 脑一样; 当不需要大屏幕显示时, 则重新令折叠屏幕折叠起来, 便于 携带和保存。
本发明还提供了一种上述的移动终端的实现方法(即实现显示屏 幕大小可变的方法), 如图 6所示, 所述实现方法包括:
51、 当折叠屏幕处于展开状态时,传感器感应到的所述展开状态 信息发送至控制芯片,控制芯片启动相应折叠屏幕的显示,令折叠屏 幕和主显示屏幕共同进行显示;
52、 当折叠屏幕处于折叠状态时,传感器感应到的所述折叠状态 信息发送至控制芯片,控制芯片关闭相应折叠屏幕的显示,令主显示 屏幕进行显示。
进一步地, 如图 5所示, 所述传感器包括传感器感应装置 410、 第一电阻 R1和第一开关 K1 ; 其中, 所述第一开关 K1的动接触点通 过一弹性件 420连接所述传感器感应装置 410, 所述第一开关 K1的 基点接地, 所述第一开关 K1的静接触点分为两路: 一路通过第一电 阻 R1连接控制芯片供电端 VCC, 另一路连接控制芯片的通用输入 / 输出接口 GPIO。
下面介绍一下上述传感器与控制芯片之间是如何实现显示屏幕 大小可变的: 为了方便理解, 以压接传感器为例进行介绍, 应当理解 的是,接近传感器的实现主要是根据霍尔效应原理来实现的, 通过使 用开关型霍尔传感器来传感折叠屏的展开与闭合,原理基本同挤压传 感器, 只不过接近传感器的开关是霍尔器件。
当折叠屏幕处于展开状态时,主显示屏幕和折叠屏幕之间的挤压 力作用在所述传感器感应装置 410, 并通过弹性件 420 (在本实施例 中, 所述弹性件为弹簧)令第一开关 K1的动接触点与静接触点相接 触, 从而使第一开关 K1导通。 第一开关 K1导通后, 控制芯片的通 用输入 /输出接口 GPIO接地, 通用输入 /输出接口 GPIO的电平被拉 低(由高电平变为低电平), 当控制芯片检测到通用输入 /输出接口 GPIO由高电平变为低电平后, 启动相应折叠屏幕的显示, 令折叠屏 幕和主显示屏幕共同进行显示。
同理, 当折叠屏幕处于折叠状态时, 主显示屏幕和折叠屏幕之间 的挤压力消失, 在弹性件 420的作用下, 第一开关 K1的动接触点与 静接触点分开, 从而使第一开关 K1断开。 第一开关 K1断开后, 控 制芯片的通用输入 /输出接口 GPIO通过第一电阻 R1连接控制芯片供 电端 VCC, 通用输入 /输出接口 GPIO的电平被拉高 (由低电平变为 高电平), 当控制芯片检测到通用输入 /输出接口 GPIO由低电平变为 高电平后, 关闭相应折叠屏幕的显示, 令主显示屏幕进行显示。
概括来说,当所述传感器为压接传感器时所述实现方法分为折叠 屏幕处于展开状态时和折叠屏幕处于折叠状态时两种:
当折叠屏幕处于展开状态时,主显示屏幕和折叠屏幕之间的挤压 力使其之间的压接传感器闭合导通; 控制芯片的通用输入 /输出接口 根据检测到的压接传感器闭合导通状态, 启动相应折叠屏幕的显示, 令折叠屏幕和主显示屏幕共同进行显示。
当折叠屏幕处于折叠状态时,主显示屏幕和折叠屏幕之间无挤压 力, 导致两者之间的压接传感器断开; 控制芯片的通用输入 /输出接 口根据检测到的压接传感器断开状态, 关闭相应折叠屏幕的显示, 令 主显示屏幕进行显示。
应当理解的是, 所述折叠屏幕为多个时, 可以根据用户需要, 令 每个折叠屏幕处于展开或折叠,控制芯片根据折叠屏幕的状态来选择 软件驱动。 在本实施例中, 因为所述折叠屏的个数为两个, 故其主要 包括四个软件驱动, 即: a、 主屏驱动; b、 主屏和右折叠屏叠加后的 驱动; c、 主屏和左折叠屏叠加后的驱动; d、 主屏和右折叠屏、 左折 叠屏叠加后的驱动。 软件驱动的基本思路是, 根据控制芯片通过传感 器开关检测到的显示屏状态来确认显示尺寸,并把显示内容按实际显 示尺寸进行显示。 如此一来, 主显示屏幕和折叠屏幕共同进行显示就 包括: 主显示屏幕和其左侧折叠屏幕共同显示、 主显示屏幕和其右侧 折叠屏幕共同显示或主显示屏幕和其两侧折叠屏幕共同显示。
综上所述, 本发明的大小可变的显示屏幕、移动终端及其实现方 法, 其中, 所述大小可变的显示屏幕包括: 主显示屏幕和折叠屏幕; 所述主显示屏幕和折叠屏幕之间转动连接,所述主显示屏幕和折叠屏 幕之间设置有用于感应折叠屏幕状态的传感器。通过传感器感应折叠 屏幕状态, 令折叠屏幕展开时与主显示屏幕共同显示; 当折叠屏幕折 叠时主显示屏幕单独进行显示, 从而实现了显示屏幕的大小可变: 屏 幕变大时,相当于平板电脑的屏幕,用户可以用来看视频、玩游戏等; 屏幕, 屏幕变小时, 相当于智能手机的屏幕, 方便用户携带以及手持 拨打电话等。
应当理解的是, 本发明的应用不限于上述的举例, 对本领域普通 技术人员来说, 可以根据上述说明加以改进或变换, 所有这些改进和 变换都应属于本发明所附权利要求的保护范围。
