现有技术中，如一个具有内屏和外屏的折叠屏手机，其中内屏包括两个子屏幕，外屏包括一个屏幕时，由于受到处理器的显示转换端口(如DPHY端口)数量(一般为2个显示转换端口)的显示限制，通常该折叠屏手机只能够显示2个子屏幕的图像数据信息，而无法同时显示所有屏幕的图像数据信息。可以理解地，可以采用新增显示转换端口的方式解决该问题，但是在原有的处理器架构上增加显示转换端口将会带来巨大的成本问题，包括硬件设备上的要求及架构设计上的要求。
进一步地，现在折叠屏手机的分辨率都是比较高的，在折叠屏手机内屏或者外屏的分辨率过高的情况下，比如2240x2480时(超过一个显示转换端口支持的显示分辨率)，需要占用处理器的2个显示转换端口。例如，折叠屏内屏的分辨率过高的情况下，需要占用处理器的2个显示转换端口显示两个子屏幕。此时折叠屏手机的内外屏幕无法同时显示。现有技术中，可将内屏和外屏分开显示，具体可通过开关切换内屏和外屏的显示转换接口通道的方式实现。
具体地，图3示出现有技术中多屏幕显示的架构示意图。从图3中可以看出，应用处理器AP具体有两个显示转换接口DPHY1和DPHY2，折叠屏手机除应用处理器还包括一个开关和3个屏幕，其中，屏幕1和屏幕2为折叠屏手机的内屏，屏幕3为折叠屏手机的外屏。可以看到，由于显示转换接口的数量限制，折叠屏手机最多能够同时显示两个子屏 幕，其中，屏幕2和屏幕3可以通过开关切换显示转换接口通道，使得屏幕2和屏幕3能够通过一个开关实现内屏和外屏的屏幕显示切换。
可以理解地，现有技术的多屏幕显示方案无法做到3个子屏幕同时显示，比如外屏和内屏同时显示的时候，只能够通过开关进行切换，无法做到内屏和外屏的同时显示。在具体的应用场景中，如对友人进行拍照时，若要求拍摄者和被拍摄者同时在屏幕上看到图像，则无法实现该要求。
鉴于此，本申请提出一种多屏幕显示电子设备(其基础架构具体可以是如图1所示的电子设备100)，用于实现电子设备多屏幕同时显示的功能。

在一实施例中，显示接口实现数据转换具体可以通过显示转接芯片实现。在本申请实施例中，为显示接口设置了开关。该开关能够改变显示接口的连接通路。在开关状态不变时，显示接口保留本身的接口功能，相当于没有设置开关；当开关状态改变时，显示接口的连接通路为显示转接芯片。通过该显示转接芯片，能够将显示接口数据转换为协议接口数据，从而根据协议接口数据实现屏幕显示。
在本申请实施例中，当电子设备的多个屏幕无法同时显示时，将应用处理器的显示接口充分利用起来，通过增加开关以及显示转接芯片，在利用显示转换接口显示屏幕的前提下，还利用开关将显示接口的转接对象转接为显示转接芯片，通过显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示，能够在保留显示接口的功能的情况下，实现电子设备的多屏幕同时显示。

进一步地，开关包括但不限于高速开关，开关的数量与显示转换接口的数量相同。
可以理解地，高速开关应用于高速电子线路，对于应用处理器这种大规模、超大规模集成电路，可以选择采用高速开关实现连接通路的转接。在一实施例中，开关用于将显示转换接口转接到屏幕显示，或者，用于选择显示接口的转接对象。开关可以设置有多个。

进一步地，显示端口还可以同时实现其他类型端口的功能，在这里应将显示端口看作一个具有集成功能的端口。具体地，显示端口还可以同时实现如USB端口的功能，如外部设备U盘可通过该显示端口实现基于USB通信协议的数据通信。
具体地，如显示端口具体为DP/USB端口。可以理解地，DP/USB接口应用于该DP/USB端口。
其中，DP/USB端口包括但不限于DP/USB2.0端口、DP/USB3.0端口等不同版本的端口。同理，显示接口也不仅限于DP接口，也可以是DP/USB3.0接口。

以上解释可参照本申请提出的多屏幕显示移动终端，在此不再一一赘述。
本申请还提出一种移动终端的多屏幕显示方法，包括：
S30：当移动终端的屏幕显示满足显示需求时，利用显示转换接口实现移动终端的多屏幕显示。
可以理解地，当移动终端的屏幕显示满足显示需求时，也即显示转换接口如DPHY接口的数量够用时，可以直接实现屏幕显示。其中，当多屏幕显示包括内屏和外屏的显示时，可以通过开关实现屏幕的切换显示，如内屏包括屏幕1和屏幕2、外屏包括屏幕3，在需要显示屏幕1和屏幕3时，可以通过开关切换显示通路，显示屏幕1和屏幕2。
S40：当移动终端的屏幕显示不满足显示需求时，利用显示转换接口显示屏幕，以及利用开关将显示接口的转换对象转接为显示转接芯片，根据显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示，其中，移动终端为上述实施例中提及的移动终端。
可以理解地，当移动终端的屏幕显示不满足显示需求时，也即显示转换接口如DPHY接口的数量不够用时，可以利于已有的显示转换接口显示对应的屏幕，缺少显示转换接口的，可以利用开关将显示接口的转换对象转接为显示转接芯片，再根据显示转接芯片将显示接口数据转换为协议接口数据，从而以协议接口数据实现移动终端多屏幕的同时显示。
在本申请实施例中，通过增加开关以及显示转接芯片，在移动终端的多个屏幕无法同时显示时，在利用显示转换接口显示屏幕的前提下，还利用开关将显示接口的转接对象转接为显示转接芯片，通过显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示，能够在保留显示接口的功能的情况下，实现移动终端的多屏幕同时显示。
进一步地，若移动终端为可折叠式移动终端，包括内屏和外屏，移动终端的内屏包括两个子屏幕，移动终端的外屏为一个屏幕，移动终端包括两个显示转换接口和一个显示 接口，开关为两个，在步骤S40中，当移动终端的屏幕显示满足显示需求时，利用显示转换接口实现移动终端的多屏幕显示，具体包括：
当移动终端处于外屏使用，内屏不使用的情况下，利用显示转换接口和开关实现移动终端的多屏幕显示。
可以理解地，如当折叠屏处于折叠状态(内折)时，移动终端处于外屏使用，内屏不使用的情况，此时可以通过转接内屏和外屏的开关，利用显示转换接口实现移动终端的多屏幕显示。
进一步地，在步骤S40中，当移动终端的屏幕显示满足显示需求时，利用显示转换接口实现移动终端的屏幕显示，具体包括：若只显示内屏的其中一个子屏幕，且该子屏幕为与外屏具有同一开关的子屏幕时，通过转接内屏和外屏的开关，利用显示转换接口实现移动终端的多屏幕显示；该子屏幕不是与外屏具有同一开关的子屏幕时，则可直接利用显示转换接口实现移动终端的屏幕显示。
当移动终端处于内屏使用，外屏不使用的情况下，利用显示转换接口和开关实现移动终端的多屏幕显示。
可以理解地，当折叠屏属于展开状态时，有一种情况是折叠屏的内屏使用，外屏不使用，这种情况一般为内屏的两个子屏幕均显示，此时可利用显示转换接口和开关实现移动终端的多屏幕显示。
若移动终端为可折叠式移动终端，包括内屏和外屏，移动终端的内屏包括两个子屏幕，移动终端的外屏为一个屏幕，移动终端包括两个显示转换接口和一个显示接口，开关为两个，则在步骤S40中，当移动终端的屏幕显示不满足显示需求时，利用显示转换接口显示屏幕，以及利用开关将显示接口的转换对象转接为显示转接芯片，根据显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示，包括：
当移动终端处于内屏和外屏均使用的情况下，利用显示转换接口和开关显示屏幕，以及利用开关将显示接口的转换对象转接为显示转接芯片，根据显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示。
可以理解地，当折叠屏属于展开状态时，有一种情况是折叠屏的内屏和外屏均使用。例如，具体的场景为对友人进行拍照时，若要求拍摄者和被拍摄者同时在屏幕上看到图像，此时折叠屏的内屏和外屏均使用；或者，在采用折叠屏开会议时，发言人需要在折叠屏的内屏进行操作，而外屏进行显示时，此时折叠屏的内屏和外屏均使用；或者，在玩家面对面进行游戏时，外屏用于展示玩家的实时战况信息时，此时折叠屏的内屏和外屏均使用。对于这些情况，可折叠式移动终端将利用显示转换接口和开关显示屏幕，以及利用开关将显示接口的转换对象转接为显示转接芯片，根据显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示。
在本申请实施例中，通过增加开关以及显示转接芯片，在移动终端的多个屏幕无法同时显示时，在利用显示转换接口显示屏幕的前提下，还利用开关将显示接口的转接对象转接为显示转接芯片，通过显示转接芯片将显示接口数据转换为协议接口数据，并根据协议接口数据实现多屏幕显示，在不改变移动终端应用处理器架构的前提下充分利用了显示接口，使得折叠屏外屏能够通过显示接口实现屏幕显示。
本申请还提出一种多屏幕显示电子设备，该电子设备屏幕的数据处理模块包括静态RAM，该多屏幕显示电子设备包括：
存储器和处理器，其中，处理器包括应用处理器，应用处理器包括数字信号微处理器、接口选择开关、显示转换接口和信号反馈引脚，其中，显示转换接口的数量小于电子设备屏幕的数量，接口选择开关用于将数字信号微处理器输出的数据转接到显示转换接口；
显示转接开关、数据选择器和屏幕信号反馈引脚，其中，显示转接开关用于切换显示转换接口输出对象的信号，并根据显示转换接口输出的数据实现屏幕显示，其中，数据选择器用于对屏幕信号反馈引脚反馈的输出信号进行信号切换，将切换后的输出信号发送到应用处理器的信号反馈引脚，以使信号反馈引脚指示应用处理器再次向屏幕输出数据。
在一实施例中，在电子设备屏幕内部的数据处理模块包括静态RAM(Random Access Memory，随机存取存储器)时，同样可以实现在如DSI的显示转换接口数量少于屏幕数量情况下，电子设备的多屏幕显示。具体实现如下：在电子设备的应用处理器中增加接口选择开关，以使将数字信号微处理器(DSP，Digital Signal Processing)输出的数据转接到不同类型的显示转换接口上，并在一些能够实现屏幕切换的显示转换接口的数据通路上设置显示转接开关，以通过该显示转接开关实现不同屏幕的数据传输。可以理解地，由于电子设备屏幕的数据处理模块包括静态RAM，应用处理器输出的数据不会丢失，因此能够实现如折叠屏设备内屏和外屏的同步显示。进一步地，由于屏幕显示的数据是持续输出的，在一实施例中在电子设备中还设置了屏幕信号反馈引脚，以及应用处理器中用于接收反馈的输出信号的信号反馈引脚，通过数据选择器使得反馈的输出信号能够进行切换，使得反馈的输出信息能够有序地传输到应用处理器，而不会引起数据冲突。
进一步地，显示转换接口包括但不限于DPHY接口。
DPHY是MIPI的一种物理层。在一实施例中，显示转换接口具体可以采用DPHY接口。其中，当显示转换接口使用DPHY接口时，电子设备中其他用于显示通信的接口也应采用相应的接口以及显示通信协议，以使电子设备能够在同一类型的显示通信协议下完成屏幕显示。
进一步地，显示转换接口为DSI接口。
DSI接口是一种应用于显示技术的串行接口，兼容DPI(显示像素接口，Display Pixel Interface)、DBI(显示总线接口，Display Bus Interface)和DCS(显示命令集，Display Command Set)，以串行的方式发送数据，DSI接口在传输数据的过程中享有自己独立的通信协议，包括数据包格式和纠错检错机制等。DSI是DPHY的一种协议层，主要用于图像输出，在一实施例中，显示转换接口具体可以采用DPHY中DSI协议的接口。
进一步地，信号反馈引脚和屏幕信号反馈引脚的类型为TE引脚。
其中，TE(tearing effect，输出引脚)可作为本实施中应用处理器的信号反馈引脚和屏幕信号反馈引脚。
进一步地，显示转换接口输出的数据为MIPI数据，显示转接开关的类型为MIPI显示转接开关，用于切换显示转换接口输出对象的信号，将MIPI数据发送到确定切换的屏幕。
可以理解地，设置MIPI显示转接开关后，可切换显示转换接口输出对象的信号，也就是决定数据输出的屏幕，如在折叠屏设备中，具体可以通过MIPI显示转接开关的信号切换决定数据传输到内屏的屏幕2或是外屏的屏幕3。
进一步地，应用处理器还包括显示接口，显示接口包括但不限于DP接口。
进一步地，电子设备的屏幕包括内屏和外屏。
可以理解地，电子设备具体可以是指具有多个子屏幕的折叠屏设备，该折叠屏设备具体包括内屏和外屏，当然，其他具有多个子屏幕的电子设备也同样能够实现多屏幕同时显示的功能。
图5示出又一种多屏幕显示电子设备架构的示意图。
从图5中可以看出，应用处理器的DSP1通过接口选择开关(开关3)实现DSI1和DSI2的转接，其中，DSI1的数据传输通路上没有设置如MIPI显示转接开关(MIPI SW，开关4)的开关时，数据将直接传输到如内屏大屏的屏幕1中，而DSI2的数据传输通路上设置有MIPI显示转接开关时，数据将基于MIPI显示转接开关切换信号的影响，选择将数据传输到内屏大屏的屏幕2或外屏的屏幕3中，从而实现不同屏幕的切换。进一步地，由于电子设备屏幕的数据处理模块包括静态RAM，应用处理器输出的数据不会丢失，因此能够实现如折叠屏设备内屏和外屏的同步显示。
进一步地，应用处理器的DSP2通过接口选择开关(开关3)还可以转接到DP接口，通过DP接口实现外接扩展屏的显示。
图6示出一种多屏幕显示电子设备在输出信号反馈层面的示意图。
从图6中可以看出，无论是内屏TE或是外屏TE，都将输出信号发送到数据选择器(MUX)中进行信号的转换，使得内屏TE和外屏TE的输出信号能够有效地反馈给应用处理器，在不引起数据冲突的前提下，指示应用处理器再次发出数据。
图7示出一种多屏幕显示电子设备实现多屏幕同时显示的流程图。
从图中可以看出，应用处理器通过MIPI显示转接开关，利用屏幕SRAM(静态RAM)对数据保存的功能，实现屏幕的显示，并通过返回输出信号的方式，持续让应用处理器输出数据，以实现屏幕的流畅显示。
该多屏幕显示电子设备利用MIPI显示转接开关和数据选择器的配合，实现在显示转换接口数量少于屏幕数量情况下，电子设备的多屏幕显示的功能。
本申请还提出一种电子设备的多屏幕显示方法，包括：
采用接口选择开关将显示数字信号微处理器输出的数据转接到显示转换接口；
若显示转换接口的传输通道上不存在显示转接开关，则根据显示转换接口输出的数据实现屏幕显示；
若显示转换接口的传输通道上存在显示转接开关，则基于显示需求，采用显示转接开关切换显示转换接口输出对象的信号，将显示转换接口输出的数据发送到确定切换的屏幕，并根据显示转换接口输出的数据实现屏幕显示，其中，在屏幕显示的过程中，采用数据选择器对屏幕信号反馈引脚反馈的输出信号进行信号切换，将切换后的输出信号发送到应用处理器的信号反馈引脚，以使信号反馈引脚指示应用处理器再次向屏幕输出数据。
参阅图5、图6和图7，可以看出电子设备的多屏幕显示方法的具体实现，在此不再赘述。
