附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的描述中所需要使用的附图作简单的介绍。下面描述中的附图仅仅是本公开的示例性实施例。
图1示出了根据本公开实施例的电子设备的一种结构示意图；
图2示出了根据本公开实施例的电子设备的另一种结构示意图；
图3示出了根据本公开实施例的电子设备的第三种结构示意图；
图4示出了根据本公开实施例的电子设备的驱动方法流程图。
具体实施方式
在下文中，将参考附图详细描述本公开的优选实施例。注意，在本说明书和附图中，具有基本上相同步骤和元素用相同的附图标记来表示，且对这些步骤和元素的重复解释将被省略。
在本公开的以下实施例中，电子设备指的以电能为工作基础且具有处理功能的设备。电子设备的具体形式包括但不限于显示器、个人计算机、个人数字助手、便携式计算机等。
图1示出了根据本公开实施例的电子设备的一种结构示意图。参见图1，电子设备100包括：显示面板集成电路110、可擦写非易失性存储器120以及处理器130。可擦写非易失性存储器120被配置为存储用于驱动显示面板集成电路110的显示面板集成电路驱动程序。处理器130被配置为基于可擦写非易失性存储器120中存储的显示面板集成电路驱动程序来驱动显示面板集成电路110。
在本公开实施例中，电子设备100中的显示面板集成电路110可以设置在显示面板下方或侧方的柔性电路板中。显示面板集成电路110是用于控制电子设备的显示面板的电路。该集成电路一般可以包括模拟电路或数字电路，当显示面板集成电路110被驱动程序驱动后，显示面板集成电路110可以进一步驱动显示面板，根据从处理器130接收的指令对显示面板进行控制，例如，启动显示面板、设置显示参数等。此外，可擦写非易失性存储器120例如可以是光擦除的可编程非易失性存储器、电擦除的可编程非易失性存储器等，例如闪存、硬盘等。处理器130可以设置在电子设备100的主板上或者设置在显示面板周围的电路板上，例如与显示面板集成电路110设置在同一柔性电路板上。处理器130可以是通用处理器，例如中央处理器，也可以是专用处理器，例如可编程逻辑电路等。
根据本公开的一个示例，处理器130可以预先获取显示面板集成电路驱动程序，然后将该显示面板集成电路驱动程序发送到可擦写非易失性存储器中，以使可擦写非易失性存储器存储显示面板集成电路驱动程序，即将该驱动程序烧录在可擦写非易失性存储器中。例如，当显示面板集成电路驱动程序有更新时，响应于显示面板集成电路驱动程序的更新，处理器130可以将更新后的显示面板集成电路驱动程序发送到可擦写非易失性存储器120中，以使可擦写非易失性存储器120重新烧录更新后的显示面板集成电路驱动程序。
在设备研发过程中，经常可能对显示面板集成电路驱动程序进行调试，由于可擦写非易失性存储器可以反复擦写，即使显示面板集成电路驱动程序不断更新，也可以重复烧录到可擦写非易失性存储器中,从而提高了研发效率，节省了资源。
根据本公开的一个示例，处理器130在调用显示面板集成电路驱动程序之前，可以先运行初始程序，再通过初始程序调用可擦写非易失性存储器中的显示面板集成电路驱动程序，以运行显示面板集成电路驱动程序。例如，在电子设备上电后，处理器130可以首先执行初始程序(例如退出睡眠(sleep out)程序和/或开始显示(display on)程序)；在这个程序运行后，会自动调取可擦写非易失性存储器中的显示面板集成电路驱动程序，从而启动显示面板集成电路驱动程序。
此外，为了使显示面板集成电路驱动程序能够与显示面板集成电路相匹 配，根据本公开的一个示例，在处理器130将新版本的显示面板集成电路的驱动程序发送到电子设备的非易失性存储装置之前，可以先获取旧版本的显示面板集成电路驱动程序，然后运行旧版本的显示面板集成电路驱动程序。在运行后并调试后，将调试后的驱动程序作为新版本发送给非易失性存储装置。从而使得显示面板集成电路驱动程序更完善，使得驱动程序和对应的驱动硬件产品的兼容性更好。
根据本公开的一个示例，电子设备中还包括通信总线，电子设备可以利用通信总线将显示面板集成电路驱动程序传输到显示面板集成电路110中以驱动显示面板集成电路。例如，该通信总线例如可以是串行外设接口总线(SPI)，或两线式串行总线(I2C)等。例如，电子设备在内部装置之间的数据传输使用SPI总线，电子设备与外部设备之间的数据传输使用I2C总线。
本公开实施例使用可擦写非易失性存储器来存储显示面板集成电路驱动程序，因此，即使显示面板集成电路驱动程序需要反复修改，也可以将驱动程序重复写入到可擦写非易失性存储器中，比之使用一次性可编程存储器，可以进行更有效改写，解决了一次性可编程存储器中的数据不能复原的技术问题。
图2示出了根据本公开实施例的电子设备的另一种结构示意图。参见图2，在前述实施例的基础上，电子设备100除了包括显示面板集成电路110、可擦写非易失性存储器120以及处理器130之外，还可以包括第二存储器140，该第二存储器140不同于可擦写非易失性存储器120。处理器130可以将显示面板集成电路驱动程序发送到可擦写非易失性存储器120的同时，还发送给第二存储器140，以使第二存储器140将显示面板集成电路驱动程序烧录到其中。
根据本公开的一个示例，第二存储器例如可以是主板上的存储器，用于存储主板驱动程序，可以将显示面板集成电路驱动程序烧录到主板驱动程序中，使得显示面板集成电路驱动程序作为主板驱动程序的一部分，这样可以通过运行主板驱动程序来运行显示面板集成电路驱动程序，从而驱动显示面板集成电路。
根据本公开的另一个示例，第二存储器还可以是电子设备中的一次性可编程存储器(OTP)。这样用户可以选择使用上述存储器中任一个中存储的驱动程序。例如，处理器130可以接收用户指令，响应于用户指令，选择基于 第二存储器中存储的显示面板集成电路驱动程序或者基于可擦写非易失性存储器中存储的显示面板集成电路驱动程序来驱动显示面板集成电路。例如，可以选择基于主板驱动程序中的显示面板集成电路驱动程序，或者基于可擦写非易失性存储器中存储的显示面板集成电路驱动程序，或者基于一次性可编程存储器中存储的显示面板集成电路驱动程序来驱动显示面板集成电路。
由于主板驱动程序中还包括其他部件的驱动程序，因此使用主板驱动程序中的显示面板集成电路驱动程序来驱动显示面板集成电路，相对于使用可擦写非易失性存储器120，运行时间更长些。可以在可擦写非易失性存储器损坏或OTP损坏不能修复时，或者在开启电子设备整个系统时，使用主板驱动程序来驱动显示面板集成电路。或者，在显示面板集成电路驱动程序已经开发成熟，可能不需再次调试更新时，可以将该驱动程序存储在OTP中，由于OTP中的存储程序使用方便，运行速度快捷，因此可以提高运行效率。
此外，根据本公开的一个示例，处理器130可以在将显示面板集成电路的驱动程序发送到电子设备的非易失性存储装置之前，从第二存储器或者可擦写非易失性存储器中获取显示面板集成电路驱动程序，并运行显示面板集成电路驱动程序，在运行后进行调试。如果调试后有更新，则可以将更新后的驱动程序发送到非易失性存储装置中，如果没有更新，则不需要再发送给非易失性存储装置。
本公开实施例通过将显示面板集成电路驱动程序存储在多个存储器中，使得用户可以根据不同情况，选择一个存储器中的驱动程序。即使某个存储器出现损坏无法修复，也不会影响驱动程序的使用。
图3示出了根据本公开实施例的电子设备的第三种结构示意图。参见图3，在前述实施例的基础上，电子设备100除了包括显示面板集成电路110、可擦写非易失性存储器120、处理器130以及第二存储器140之外，还可以包括寄存器150。另外，处理器130中还包括比较器131。
寄存器150被配置为存储用于选择显示面板集成电路驱动程序的选择指令代码。比较器131被配置为将接收的用户指令与寄存器中的选择指令代码进行匹配，基于匹配结果选择一个存储器中的驱动程序。例如，可以选择基于非易失性存储装置，或基于第二存储器中存储的显示面板集成电路驱动程序来驱动显示面板集成电路。例如，寄存器150中的选择指令代码可以包括选择非易失性存储装置的指令代码001、选择第二存储器的指令代码002，处 理器130接收到用户指令后，将该指令转换为与指令代码相同格式的代码，比较器131可以基于转换格式后的代码与寄存器中存储的代码进行比较，以确定用户选择的存储器。
本公开实施例通过寄存器和比较器，可以根据用户选择来确定用户期望使用的存储器中的显示面板集成电路驱动程序，进一步提高了驱动程序开发的效率。
图4示出了根据本公开实施例的电子设备的驱动方法流程图。该驱动方法与前述实施例中的电子设备的工作方式对应，为了说明书的简洁，以下仅作简要介绍，重复之处不再赘述。参见图4，电子设备驱动方法400包括以下步骤。
在步骤S401中，对电子设备进行上电。
在步骤S402中，调用可擦写非易失性存储器中的显示面板集成电路的驱动程序。
在步骤S403中，基于可擦写非易失性存储器中的显示面板集成电路的驱动程序来驱动显示面板集成电路。
根据本公开的一个示例，首先将显示面板集成电路驱动程序发送到可擦写非易失性存储器中，这样可擦写非易失性存储器可以将该驱动程序烧录到其中。
此外，在S402中，可以先执行初始程序，例如退出睡眠(sleep out)程序和/或开始显示(display on)程序；通过这两个程序调用可擦写非易失性存储器中的显示面板集成电路驱动程序。
此外，当显示面板集成电路的驱动程序有更新时，响应于显示面板集成电路的驱动程序的更新，将更新后的显示面板集成电路驱动程序发送到可擦写非易失性存储器中，这样可擦写非易失性存储器重新烧录更新后的显示面板集成电路驱动程序。
例如在研发过程中，需要对驱动程序进行调试，首先获取更新前的显示面板集成电路驱动程序，并运行更新前的显示面板集成电路驱动程序，以对显示面板集成电路驱动程序进行更新。之后，将更新后的显示面板集成电路驱动程序发送到可擦写非易失性存储器。
此外，根据本公开的另一个示例，在将显示面板集成电路驱动程序发送到可擦写非易失性存储器的同时，还可以将显示面板集成电路驱动程序发送 到电子设备的第二存储器中，以使第二存储器存储显示面板集成电路驱动程序。这样，用户可以选择一个存储器中的驱动程序进行使用。电子设备响应于用户的选择指令，选择基于第二存储器中存储的显示面板集成电路驱动程序或者基于可擦写非易失性存储器中存储的显示面板集成电路驱动程序来驱动显示面板集成电路。此外，显示面板集成电路在启动后，可以启动电子设备的显示面板。
例如，第二存储器可以是主板上的存储器，存储主板驱动程序，可以将显示面板集成电路驱动程序烧录到主板驱动程序中。第二存储器也可以是电子设备中的一次性可编程存储器(OTP)。基于用户指令，电子设备的处理器可以选择基于主板驱动程序中存储的显示面板集成电路驱动程序或者基于可擦写非易失性存储器中存储的显示面板集成电路驱动程序或者基于一次性可编程存储器中存储的显示面板集成电路驱动程序来驱动显示面板集成电路。
此外，电子设备还可以包括寄存器，在寄存器中存储用于选择驱动程序的选择指令代码。当接收到用户指令后，处理器中的比较器将接收的用户指令与寄存器中的选择指令代码进行匹配，并基于匹配结果选择基于第二存储器，或基于非易失性存储装置中存储的显示面板集成电路驱动程序来驱动显示面板集成电路。
此外，处理器调用了可擦写非易失性存储器中的显示面板集成电路驱动程序后，电子设备中的数据线或栅线可以将可擦写非易失性存储器中的显示面板集成电路驱动程序传输到显示面板集成电路中以驱动显示面板集成电路。
本公开实施例通过使用可擦写非易失性存储器存储显示面板集成电路驱动程序，在需要对驱动程序不断调试时，可随时将重新调试的驱动程序重新写入到可擦写非易失性存储器中，比之使用一次性可编程存储器，有效地节省了研发资源，提高了研发效率。
本领域普通技术人员可以意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以硬件、固件、软件或者三者的任意结合方式来实现。并且软件模块可以置于任意形式的计算机存储介质中。为了清楚地说明硬件和软件的可互换性，在上述说明中已经按照功能一般性地描述了各示例的组成及步骤。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来 使用不同方法来实现所描述的功能，但是这种实现不应认为超出本公开的范围。
