Description

显示设备 技术领域
本公开实施例涉及显示设备。
背景技术
平板电脑是一种小型、无须翻盖、没有键盘、方便携带但却功能完整的PC(Personal Computer，个人电脑)。平板电脑以触摸屏作为基本的输入设备，它拥有的触摸屏(也称为数位板技术)允许用户通过触控笔或数字笔来进行作业而不是传统的键盘或鼠标。用户可以通过内建的手写识别、屏幕上的软键盘或者语音识别实现输入。
平板电脑的尺寸较小，集成度高，所以其适用方便性要比普通的笔记本好的多。但由于其没有键盘，在办公以及游戏等方面的应用性能要比普通的笔记本要低一些。
发明内容
本公开实施例提供了一种显示设备，包括主机、显示面板、触控面板以及投影构件，其中，所述触控面板与所述显示面板的相对位置为可变的，所述显示面板构造为用于显示一显示图像；所述投影构件构造为在所述显示面板与所述触控面板不重合的情况下，将一投影图像投影到所述触控面板；所述触控面板构造为用于检测一触控操作并基于该触控操作生成触控信号；并且，所述主机构造为用于根据所述触控信号处理所述显示面板的显示图像。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例或相关技术描述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涉及本公开的一些实施例，并非对本公开的限制。
图1为本公开实施例提供的显示设备在一模式下的示意图；
图2为本公开实施例提供的显示设备在另一模式下的示意图；
图3为图1所示显示设备在图1所示模式下投影虚拟键盘的示意图；
图4为本公开实施例提供的一种主机示意图；
图5为本公开实施例提供的另一种主机示意图。
具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
本公开的实施例提供一种显示设备，能够解决了现有的显示设备没有键盘便携性好但降低了使用性能的问题。
以下将结合图1-图3对本公开实施例提供的显示设备进行说明，显示设备100包括主机1，显示面板2、以及与显示面板2枢接的触控面板3。显示面板2与触控面板3在其各自的一边缘彼此可转动地连接，且显示面板2与显示面板2之间的夹角α例如可以为0°至180°。显示设备100例如还包括位于显示面板2上的诸如投影镜头21的投影构件；触控面板3用于检测触控操作并生成触控信号；主机1用于根据触控信号处理显示面板的图像信息。
在第一模式下，如图2所示，显示面板2与触控面板3彼此重合，其间夹角α为0°，此时，用户能够透过触控面板3观看显示面板2显示的图像信息并根据显示面板2显示的图像信息对触控面板3进行触控操作生成触控信号，以控制显示面板2显示的图像信息。
在第二模式下，如图1所示，显示面板2与触控面板3打开为具有大于零的夹角α，此时，用户能够直接观看显示面板2的显示的图像信息，显示面板2上的投影镜头21打开，将投影图像投影在触控面板3，以便用户根据投影图像对触控面板3进行触控操作生成触控信号，以控制显示面板2显示的图像信息。
需要说明的是，本公开实施例中，触控面板与显示面板连接并可开合，可以如现有的笔记本电脑显示屏和主机的硬性连接方式相同，这里不作详细说明。本公开实施例中，触控面板的透过率例如大于等于75％，以在第一模式下，透过该触控面板依然可以清晰呈现显示面板的图像。当然，触控面板 的透过率还可以是小于75％，在此情况下，可通过提高显示面板的显示亮度提高清晰度。本公开实施例仅以触控面板透过率大于等于75％为示例进行详细说明。显示设备包括主机，主机可以包括CPU、显卡、驱动模块等具有图像处理功能的模块，主机用于根据触控信号处理显示面板的图像信息。本公开实施例中，主机在第一模式和第二模式下均可以对根据触控操作产生的触控信息进行处理。
第一模式下，如图2所示，显示面板2与触控面板3合拢为彼此重合，例如触控面板3位于显示面板2的上面，用户可以通过触碰触控面板3控制显示面板2显示的图像信息。
第二模式下，如图1所示，显示面板2与触控面板3打开一定角度(例如显示面板2与触控面板3之间夹角α等于90°，当然也可以是其他任意角度)，显示面板2的投影镜头21打开，将一投影图像投影在触控面板3进行显示，而显示面板2可以显示一显示图像。
需要说明的是，投影图像可以包括：虚拟键盘或显示图像。
显示图像例如可以为一网页图像。例如，在需要同时打开第一网页和第二网页的情况下，显示面板2可以显示第一网页图像，而第二网页图像作为投影图像可通过投影镜头21投影到触控面板3上，此时，用户可以在触控面板3对该投影图像进行触控操作。
或者，如图3所示，显示面板2可以是显示word文档，通过投影镜头21投影在触控面板3的投影图像例如为虚拟键盘，此时，用户可以通过在虚拟键盘进行触控操作，完成显示面板2上word文档的编辑。这里需要说明的是，虚拟键盘可以是预先设置的投影图像，即主机可以控制显示面板的投影镜头打开，用于投影特定的图像，如虚拟键盘。
通过以上所述，本公开实施例提供的显示设备在不同模式下，可以实现不同的显示功能，不仅方便携带且方便使用，极大地增强了显示设备的使用多样性。
可选地，主机1还可用于控制投影镜头21改变投影角度或将投影图像进行缩放，使在触控面板上的投影面积与触控面板的面积匹配。
考虑到显示设备的显示面板相对触控面板改变开合角度时，投影镜头的投影图像有可能受到影响，例如在投影图像超出触控面板的面积的情况下， 有必要对投影镜头的投影图像进行修正，因此，主机还用于控制投影镜头改变投影角度或将投影图像进行缩放后进行投影，使在触控面板上的投影面积与触控面板的面积匹配。例如，在显示面板与触控面板之间的夹角改变时，主机控制投影镜头改变投影角度或将投影图像进行缩放后进行投影以匹配触控面板的面积。显示面板与触控面板之间的夹角的检测方式可以采用检测显示面板和触控面板之间转轴的角度的方式，或者在显示面板和/或触控面板上设置能够检测二者开合角度的传感器的方式来实现。本公开实施例中，投影镜头能够始终使投影图像准确的投影至触控面板的区域内。
本公开实施例中，如图1、图3所示，显示面板2设置于主机1上。可选地，在另一实施例中，显示面板2与主机1可以是彼此物理分离的，通过wifi或蓝牙等实现通讯。本公开实施例中，如图1、图3所示，显示面板2与触控面板3彼此枢接。在另一实施例中，显示面板2与触控面板3可以彼此物理分离。在显示面板2、触控面板3与主机1彼此分离的情况下，显示面板2和触控面板3可分别与主机1通过wifi或蓝牙等实现通讯。本公开实施例仅以图1所示的为例进行详细说明，而并不旨在限制显示面板、触控面板与主机的位置关系。
可选的，如图4所示，主机1包括第一接口11和第二接口12；主机1通过第一接口11驱动显示面板的图像信息；主机1通过第二接口12驱动投影镜头打开，并生成投影图像。
例如，主机1包括双显显卡，主机包括第一接口和第二接口可以是双显显卡包括第一接口和第二接口。进一步的，第一接口可以是VGA(Video Graphics Array，视频图形阵列)接口，第二接口可以是DVI(Digital Visual Interface，数字视频)接口。需要说明的是，主机驱动显示面板的显示图像和投影图像的具体方式不局限于上述方式，本公开实施例仅以上述为例进行说明。
可选的，显示设备还包括开关；在第一模式下，开关闭合，将第二接口关闭；在第二模式下，开关打开，将第二接口开启。即开关控制第二模式的开启或关闭状态，主机再确定是否开启投影镜头。
在一个示例中，如图5所示，第一接口11和第二接口12串联，第二接口12与开关并联。在第一模式下，开关闭合将第二接口短路，显示面板通过 第一接口显示图像；在第二模式下，开关打开，投影镜头开启并生成投影图像，投影镜头将投影图像投影在触控面板。
在一个示例中，开关可以为行程开关；其中，开关包括开关本体和触发结构；在开关本体和触发结构接触的情况下，开关闭合；在开关本体和触发结构断开的情况下，开关打开。例如，行程开关还可以是以其他形式达到开关的开启和闭合，本公开实施例仅以上述为例进行详细说明。
可选的，在显示面板与触控面板之间的夹角小于预设角度的情况下，开关本体和触发结构接触；在显示面板与触控面板之间的夹角α大于等于预设角度的情况下，开关本体和触发结构断开。即开关的打开和闭合是由显示面板与触控面板之间的夹角决定的，预设角度可以是根据需要设定的任意角度，例如可以是30°、60°或90°等。
或者，如图1所示，开关本体4设置于显示面板2上，触发结构5设置于触控面板3上。此时，若触控面板3与显示面板2分开，会使得触发结构与开关本体断开，开关打开；若触控面板3与显示面板2贴合，触发结构与开关本体接触，开关闭合。
或者，可选的，开关本体和触发结构可以是均设置在显示面板。再或者，开关本体和触发结构可以是均设置在触控面板上。
可选的，触控面板为电容式触控面板、电阻式触控面板或电感式触控面板。本公开实施例对触控面板的触控方式不作具体限定。
