Description

液晶显示器的启动方法 技术领域
本发明总体说来涉及显示技术领域，更具体地讲，涉及一种能够加速液晶显示器启动时间的启动方法。
背景技术
Mura(云纹)是指显示屏幕亮度不均匀而产生的各种污染斑块的现象，其形成原因可能是LCD(液晶显示器)贴附彩色滤片引入的显示瑕疵，也可能是液晶屏本身制造过程中引入的。Mura的存在使得显示屏幕在显示影像，尤其是显示大面积平滑区域的影像时，显示结果异常，画面亮度不均匀，降低了观众的观看舒适度。demura就是在已知Mura区域的位置以及Mura程度等信息的前提下，对输入到液晶屏不同区域内的影像信号进行相应的亮度调制，以提高输出影像画面亮度的一致性，提升观众的观看体验。
现有技术中，液晶显示器的光电板(即，X board)与控制板(即，Control board)在生产过程中为单独制造，demura信息(即，用于去除Mura的代码)在出厂时一般都保存在光电板上的闪存(Flash)中，在组装为液晶显示器成品时，会利用软排线将控制板与光电板连接在一起。每当液晶显示器启动时，控制板会从光电板上的闪存中读取全部的demura信息，如果读取失败，则需控制板重新从光电板上的闪存中读取demura信息，但由于全部的demura信息的长度较大，这将导致液晶显示器的启动时间过长。

具体实施方式
现将详细描述本发明的示例性实施例，所述实施例的示例在附图中示出，其中，相同的标号始终指的是相同的部件。
图1示出根据本发明示例性实施例的液晶显示器的内部结构的示意图。参照图1，1为液晶显示器的光电板(即，X board)，在该光电板上具有闪存(Flash)，2为液晶显示器的控制板(即，control board)，在该控制板上具有定时器/计数器控制寄存器(TCON，以下简称控制器)和闪存(Flash)。
一般液晶显示器的光电板和控制板为相互独立分开生产的两块板，在出厂时操作人员会对液晶显示器的显示屏幕进行调试，并将调试后的用于指示执行预定屏幕处理的控制代码及相应的校验码保存到液晶显示器的光电板上的闪存中，在组装为液晶显示器的成品时，液晶显示器的光电板上的闪存与控制板上的控制器之间通过软排线连接以进行相互间的通讯，两者之间的通讯距离较远，阻抗较大，干扰较多，控制板上的控制器与控制板上的闪存之间也通过软排线连接以进行相互间的通讯，但两者之间的通讯距离较近，阻抗较小，干扰少。
图2示出根据本发明示例性实施例的液晶显示器的启动方法的流程图。
参照图2，在步骤S10中，在接收到用于启动液晶显示器的控制命令之后，从液晶显示器的光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码的校验码。
可选地，作为示例，可根据用户的输入来产生用于启动液晶显示器的控制命令，例如，用户的输入可包括：用户对液晶显示器的显示面板上的启动按钮的选择操作，或者用户对液晶显示器的遥控器上的启动按钮的选择操作。当接收到用户对上述启动按钮的选择操作之后，则产生相应的用于启动液晶显示器的控制命令。
这里，作为示例，所述预定屏幕处理可包括去除屏幕云纹的处理，然而本发明不限于此。可选地，在接收到用于启动液晶显示器的控制命令之后，为液 晶显示器的光电板和控制板上电，然后控制板上的控制器从液晶显示器的光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码的校验码。
可选地，根据本发明示例性实施例的液晶显示器的启动方法在执行步骤S10之前可还包括步骤：预先将用于指示执行预定屏幕处理的控制代码和对应的校验码保存到液晶显示器的光电板上的闪存中。这里，在出厂时，在液晶显示器的光电板上的闪存中就已存储了用于指示执行预定屏幕处理的控制代码以及对应的校验码。应理解，可利用现有的各种方法来生成与用于指示执行预定屏幕处理的控制代码对应的校验码。
在步骤S20中，将从光电板上的闪存中读取的校验码与液晶显示器的控制板上的闪存中存储的用于指示执行预定屏幕处理的控制代码的校验码进行比较。
如果从光电板上的闪存中读取的校验码与控制板上的闪存中存储的校验码一致，则执行步骤S30：从控制板上的闪存中读取用于指示执行预定屏幕处理的控制代码。这里，由于控制板上的控制器从控制板上的闪存中读取用于指示执行预定屏幕处理的控制代码，与现有的控制板上的控制器从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码的方式相比有效减少了读取控制代码过程的通讯距离，并减少了控制代码传输过程中的干扰，缩短了液晶显示器的启动时间。
如果从光电板上的闪存中读取的校验码与控制板上的闪存中存储的校验码不一致，则执行步骤S40：从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码，并将从光电板上的闪存中读取的用于指示执行预定屏幕处理的控制代码和从光电板上的闪存中读取的校验码保存到控制板上的闪存中。
在步骤S50中，基于读取的用于指示执行预定屏幕处理的控制代码执行所述预定屏幕处理。
具体说来，如果从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码，则在步骤S50中基于从光电板上的闪存中读取的用于指示执行预定屏幕处理的控制代码执行所述预定屏幕处理；如果从控制板上的闪存中读取用于指示执行预定屏幕处理的控制代码，则在步骤S50中基于从控制板上的闪存中读取的用于指示执行预定屏幕处理的控制代码执行所述预定屏幕处理。
作为示例，在预定屏幕处理为去除屏幕云纹的处理的情况下，所述用于指 示执行预定屏幕处理的控制代码指示液晶显示器的显示屏幕上的各像素对应的电压值，则相应地，在步骤S50中根据液晶显示器的显示屏幕上的各像素对应的电压值调节液晶分子的翻转角度，从而改变显示屏幕上各像素的显示亮度。这里，应理解，根据液晶显示器的显示屏幕上的各像素对应的电压值调节液晶分子的翻转角度，从而改变显示屏幕上各像素的显示亮度的方法为本领域的公知常识，本发明对此部分内容不再赘述。
下面参照图3来详细描述在初次执行本发明示例性实施例所述的启动方法时的步骤。
图3示出根据本发明示例性实施例初次执行所述液晶显示器的启动方法时的步骤的流程图。
参照图3，在步骤S301中，在接收到用于启动液晶显示器的控制命令之后，从液晶显示器的光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码的校验码。
这里，图3中的步骤S301与图2中的步骤S10相同，对此不再赘述。
在步骤S302中，将从液晶显示器的光电板上的闪存中读取的用于指示执行预定屏幕处理的控制代码的校验码与液晶显示器的控制板上的闪存中存储的初始校验码进行比较。
可选地，根据本发明示例性实施例的液晶显示器的启动方法在执行步骤S302之前可还包括步骤：预先将用于指示执行预定屏幕处理的初始控制代码和对应的初始校验码保存到液晶显示器的控制板上的闪存中。
如果从光电板上的闪存中读取的校验码与控制板上的闪存中存储的初始校验码一致，则执行步骤S303：从液晶显示器的控制板上的闪存中读取用于指示执行预定屏幕处理的初始控制代码。作为示例，在预定屏幕处理为去除屏幕云纹的处理情况下，初始校验码可指示液晶显示器的显示屏幕不存在云纹现象，此时，如果从光电板上的闪存中读取的校验码与初始校验码一致，则表明无需对显示屏幕上各像素的显示亮度进行调整。
如果从光电板上的闪存中读取的校验码与控制板上的闪存中存储的初始校验码不一致，则执行步骤S304：从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码。
在步骤S305中，根据从光电板上读取的用于指示执行预定屏幕处理的控制代码生成对应的校验码。这里，可利用现有的各种方法根据读取的用于指示执行预定屏幕处理的控制代码生成对应的校验码。
在步骤S306中，将从光电板上的闪存中读取的校验码与生成的校验码进行比较。
如果从光电板上的闪存中读取的校验码与生成的校验码不一致，则返回执行步骤S304，重新从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码。
如果从光电板上的闪存中读取的校验码与生成的校验码一致，则执行步骤S307：将从光电板上的闪存中读取的用于指示执行预定屏幕处理的控制代码和从光电板上的闪存中读取的校验码均保存到控制板上的闪存中。
在步骤S308中，执行所述预定屏幕处理。
具体说来，如果从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码，则在步骤S308中基于读取的用于指示执行预定屏幕处理的控制代码执行所述预定屏幕处理；如果从控制板上的闪存中读取用于指示执行预定屏幕处理的初始控制代码，则在步骤S308中基于读取的用于指示执行预定屏幕处理的初始控制代码执行所述预定屏幕处理。
可选地，在所述预定屏幕处理为去除屏幕云纹的处理的情况下，用于指示执行预定屏幕处理的初始控制代码可指示液晶显示器的显示屏幕上的各像素对应的初始电压值，因此，在步骤S308中根据液晶显示器的显示屏幕上的各像素对应的初始电压值来控制显示屏幕上各像素的显示亮度。
采用本发明示例性实施例的液晶显示器的启动方法，仅在初次执行所述启动方法时需从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码，此后仅需从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码的校验码即可，有效减少了通讯时间，从而提高了液晶显示器的启动时间。此外，在校验码匹配一致的情况下，控制器是从控制板上的闪存中读取用于指示执行预定屏幕处理的控制代码，由于控制器和控制板上的闪存处于同一PCB板上，使得通讯距离短，阻抗小，干扰少。
图4示出根据本发明另一示例性实施例的液晶显示器的内部结构的示意图。参照图4，1为液晶显示器的光电板(即，X board)，在该光电板上具有闪存 (Flash)，2为液晶显示器的控制板(即，control board)，在该控制板上具有闪存(Flash)。
总体说来，根据本发明另一示例性实施例的液晶显示器的启动方法在接收到用于启动液晶显示器的控制命令之后，从液晶显示器的光电板上的闪存中顺序读取m段用于指示执行预定屏幕处理的控制代码，然后基于读取的m段用于指示执行预定屏幕处理的控制代码执行所述预定屏幕处理。
下面参照图5来详细描述根据本发明另一示例性实施例的液晶显示器的启动方法的步骤。
图5示出根据本发明另一示例性实施例的液晶显示器的启动方法的流程图。
在步骤S100中，在接收到用于启动液晶显示器的控制命令之后，从液晶显示器的光电板上的闪存中读取m段用于指示执行预定屏幕处理的控制代码中的第j段用于指示执行预定屏幕处理的控制代码和第j段用于指示执行预定屏幕处理的控制代码对应的第一校验码。可选地，这里可将读取的第j段用于指示执行预定屏幕处理的控制代码和对应的第一校验码存入液晶显示器的控制板上的控制器的内存中。这里，作为示例，j的初始值为1，且j∈[1,m]，m为大于0的自然数。
可选地，作为示例，可根据用户的输入来产生用于启动液晶显示器的控制命令，例如，用户的输入可包括：用户对液晶显示器的显示面板上的启动按钮的选择操作，或者用户对液晶显示器的遥控器上的启动按钮的选择操作。当接收到用户对上述启动按钮的选择操作之后，则产生相应的用于启动液晶显示器的控制命令。
这里，作为示例，所述预定屏幕处理可包括去除屏幕云纹的处理，然而本发明不限于此。可选地，根据本发明另一示例性实施例的液晶显示器的启动方法在执行步骤S100之前还包括步骤：将用于指示执行预定屏幕处理的控制代码划分为m段；针对所述m段用于指示执行预定屏幕处理的控制代码分别生成对应的m个校验码；将所述m段用于指示执行预定屏幕处理的控制代码以及生成的m个校验码均保存到液晶显示器的光电板上的闪存中。这里，在出厂时，在液晶显示器的光电板上的闪存中就已存储了m段用于指示执行预定屏幕处理的控制代码以及对应的m个校验码。应理解，可利用现有的各种方法来生成与用于指示执行预定屏幕处理的控制代码对应的校验码。
在步骤S200中，根据读取的第j段用于指示执行预定屏幕处理的控制代码生成对应的第二校验码。这里，可利用现有的各种方法来根据读取的用于指示执行预定屏幕处理的控制代码生成对应的校验码。
在步骤S300中，将从光电板上的闪存中读取的第j段用于指示执行预定屏幕处理的控制代码的第一校验码与生成的第j段用于指示执行预定屏幕处理的控制代码的第二校验码进行比较。
如果第一校验码与第二校验码不一致，则返回执行步骤S100。这里，如果第一校验码与第二校验码不一致，则表明控制板上的控制器从光电板上的闪存中读取的第j段用于指示执行预定屏幕处理的控制代码存在错误，因此需返回执行步骤S100重新从光电板上的闪存中读取的第j段用于指示执行预定屏幕处理的控制代码。
如果第一校验码与第二校验码一致，则执行步骤S400：检测j是否等于m。
当j≠m时，则执行步骤S500：使得j＝j+1，并返回执行步骤S100。
当j＝m时，表明控制板上的控制器已经从光电板上的闪存中读取完全部m段用于指示执行预定屏幕处理的控制代码，则在步骤S600中，基于读取的m段用于指示执行预定屏幕处理的控制代码执行所述预定屏幕处理。
可选地，在所述预定屏幕处理为去除屏幕云纹的处理的情况下，m段用于指示执行预定屏幕处理的控制代码指示液晶显示器的显示屏幕上的各像素对应的电压值，则相应地，在步骤S600中根据液晶显示器的显示屏幕上的各像素对应的电压值调节液晶分子的翻转角度，从而改变显示屏幕上各像素的显示亮度。这里，应理解，根据液晶显示器的显示屏幕上的各像素对应的电压值调节液晶分子的翻转角度，从而改变显示屏幕上各像素的显示亮度的方法为本领域的公知常识，本发明对此部分内容不再赘述。
这里，应理解，图5所示出的是在j的初始值为1的情况下的液晶显示器的启动方法的流程图，然而本发明不限于此，还可以是j的初始值为m，此时，相应地在步骤S400中则为检测j是否等于0，当j≠0时，则在步骤S500中使得j＝j-1，并返回执行步骤S100，当j＝0时，表明控制板上的控制器已经从光电板上的闪存中读取完全部m段用于指示执行预定屏幕处理的控制代码，然后继续执行步骤S600。
采用本发明示例性实施例的液晶显示器的启动方法，在从光电板上的闪存中读取用于指示执行预定屏幕处理的控制代码时分段读取，一旦任一段的控制代码对应的第一校验码与第二校验码不一致，仅需重复读取该段的用于指示执行预定屏幕处理的控制代码，而不必重新读取全部的用于指示执行预定屏幕处理的控制代码，有效节省了液晶显示器的启动时间。
上面已经结合具体示例性实施例描述了本发明，但是本发明的实施不限于此。在本发明的精神和范围内，本领域技术人员可以进行各种修改和变型，这些修改和变型将落入权利要求限定的保护范围之内。
