附图说明
附图是用来提供对本公开的进一步理解,并且构成说明书的一部分,与下面的具体实施方式一起用于解释本公开,但并不构成对本公开的限制。在附图中:
图1为本公开的实施例的显示装置的检测方法的一种流程示意图;
图2为本公开的实施例的显示装置的检测方法的另一种流程示意图。
具体实施方式
为使本领域技术人员更好地理解本公开的技术方案,下面结合附图和具体实施方式对本公开作进一步详细描述。
以下将参照附图更详细地描述本公开。在各个附图中,相同的元件采用相同或相似的附图标记来表示。为了清楚起见,附图中的各个部分没有按比例绘制。此外,在图中可能未示出某些公知的部分。
在下文中描述了本公开的许多特定的细节,例如部件的结构、材料、尺寸、处理工艺和技术,以便更清楚地理解本公开。但正如本领域的技术人员能够理解的那样,可以不按照这些特定的细节来实现本公开。
如1图所示,本公开实施例提供一种显示装置的检测方法,所述显示装置包括多个子显示屏。
具体地,本公开实施例的检测方法适用的显示装置是由多个子显示屏组成的,即每个子显示屏显示整体画面的一部分,当每个子显示屏均正常显示时,所有的子显示屏显示的画面组成一个完整的画面;且各子显示屏的工作相对独立,即,一个子显示屏是否正常与其它子显示屏无关。
本公开实施例的检测方法可包括如下步骤S11至S15。
S11、向显示装置发送第一指令,以使显示装置的所有子显示屏均显示第一测试画面。
也就是说,向显示装置发送第一指令,使得显示装置的所有子显示屏在同一时刻均显示同一画面,即第一测试画面。
本公开的实施例中,所述第一测试画面可能为特定颜色的纯色画面,例如,可能为白色、黑色、蓝色、绿色、红色、或黄色的纯色画面。
而且,本公开的实施例中,所提及的“同一时刻”可能具有一 定裕度,且“同一画面”可能具有一定容差。
例如,只要各子显示屏显示画面的时刻之间的差值不大于预定时长,均可看作各子显示屏在同一时刻显示画面,只要各子显示屏显示的画面之间的色差不大于预定色差值,均可看作各子显示屏显示同一画面。所述预定时长和所述预定色差值可根据需要进行设定,本公开不对其进行具体限定。例如,所述预定时长可设定为使得子显示屏显示画面的时刻之间的差值不大于该预定时长时,人眼识别不出子显示屏显示画面的时刻差异或者可容忍该差异;所述预定色差值可设定为使得子显示屏显示的画面之间的色差不大于该预定色差值时,人眼识别不出子显示屏显示的画面之间的差异或者可容忍该差异。
S12、根据第一测试画面的显示情况,判断是否所有子显示屏均符合显示标准。
具体地,各子显示屏显示画面时,可生成包含其显示画面的实际显示时刻和实际显示画面的属性(例如颜色)等相关信息的信号,可通过分析该信号来判断子显示屏是否符合显示标准。
例如,可通过比较各子显示屏显示第一测试画面的实际显示时刻与第一测试画面的预定显示时刻来判断各子显示屏是否符合显示标准,如果子显示屏显示第一测试画面的实际显示时刻与第一测试画面的预定显示时刻之间的差值大于第一预定值,则可看作该子显示屏不符合显示标准。当然,也可通过比较各子显示屏显示第一测试画面的实际显示画面的属性与第一测试画面的预定属性来判断各字显示屏是否符合标准,如果子显示屏显示第一测试画面的实际显示画面的属性与第一测试画面的预定属性之间的差异大于第二预定值,例如,如果子显示屏显示第一测试画面的实际显示画面的颜色与第一测试画面的预定颜色之间的色差大于第二预定值,则判断该子显示屏不符合显示标准。
例如,可以事先统计人眼观察认为各子显示屏在同一时刻显示第一测试画面时各子显示屏显示第一测试画面的实际显示时刻之间的差值,并将这些差值的均值作为第一预定值,如果子显示屏显示第一测试画面的实际显示时刻与第一测试画面的预定显示时刻之间的 差值大于该第一预定值,则可看作该子显示屏不符合显示标准;还可以事先统计人眼观察认为各子显示屏在同一时刻显示第一测试画面时各子显示屏的实际显示画面的属性之间的差异,并将这些差异的均值作为第二预定值,如果子显示屏显示第一测试画面的实际显示画面的属性与第一测试画面的预定属性之间的差异大于该第二预定值,则判断该子显示屏不符合显示标准。
应当理解,如果子显示屏不生成包含其显示画面的实际显示时刻和实际显示画面的属性(例如颜色)等相关信息的信号,则可能是该子显示屏无法进行显示,因此该子显示屏也不符合显示标准。
另外,还可以考虑各子显示屏应当显示的画面尺寸,例如,如果子显示屏实际显示的画面尺寸(例如,实际显示的第一测试画面的画面尺寸)小于其应当显示的画面尺寸(例如,第一测试画面的预定尺寸)的量超出预定量,例如5%或以上,则认为该子显示屏没有完全显示第一测试画面,不符合显示标准。应当理解,所述预定量可根据需要预先确定,原则上,可以将人眼观察认为子显示屏没有完全显示第一测试画面时子显示屏实际显示的画面尺寸小于其应当显示的画面尺寸的最小量确定为所述预定量。
当然,可以结合上述一种或多种因素来判断子显示屏是否符合显示标准,本公开对此不进行具体限定。
S13、若至少一个子显示屏不符合显示标准,则对不符合显示标准的子显示屏进行第一复位操作,并使进行了第一复位操作的子显示屏重新显示第一测试画面。
对不符合显示标准的子显示屏进行第一复位操作相当于对该子显示屏进行“热启动”。具体的,本公开不限定对不符合显示标准的子显示屏进行第一复位操作的具体方式,例如,可以通过显示装置的控制器对不符合显示标准的子显示屏进行第一复位操作,也可以通过显示装置显示提示信息提示工作人员按下与不符合显示标准的子显示屏对应的复位键来对不符合显示标准的子显示屏进行第一复位操作。
S14、根据第一测试画面的显示情况,判断重新显示第一测试画 面的子显示屏是否符合显示标准。
具体地,重新显示第一测试画面的子显示屏仍可生成包含其显示第一测试画面的实际显示时刻和实际显示画面的属性等相关信息的信号,可通过分析该信号来判断重新显示第一测试画面的子显示屏是否符合显示标准,细节可参照步骤S12的相关描述,此处不再赘述。
S15、若重新显示第一测试画面的子显示屏仍不符合显示标准,则使用备用子显示屏替换仍不符合显示标准的子显示屏。
即,若进行第一复位操作后,子显示屏仍然不能正常显示,则认为子显示屏已经损坏了,从而可将该子显示屏替换掉。
本公开实施例的显示装置的检测方法中,通过判断子显示屏是否符合显示标准、对不符合显示标准的子显示屏进行第一复位操作、使进行了第一复位操作的子显示屏重新显示第一测试画面、以及再判断重新显示第一测试画面的子显示装置是否符合显示标准,能够最大程度上将显示不正常或者损坏的子显示屏找出,并修正或者替换,从而保证了显示装置在之后能够正常显示。
如图2所示,本公开实施例还提供一种显示装置的检测方法,所述显示装置包括多个子显示屏。
本公开实施例的检测方法适用的显示装置是由多个子显示屏组成的,即每个子显示屏显示整体画面的一部分,当每个子显示屏均正常显示时,所有的子显示屏显示的画面组成一个完整的画面;且各子显示屏的工作相对独立,即,一个子显示屏是否正常与其它子显示屏无关。
在一些实施方式中,显示灯为LED灯珠。
具体的,该显示装置可为透明LED显示装置,可运用于玻璃幕墙上、商店橱窗中、大型艺术演出中的显示等,运用于大型艺术演出中的显示装置可由几百块、几千块甚至几万块子显示屏组成。
以下以显示灯为LED灯珠、显示装置为透明LED显示装置为例进行说明。
本公开实施例的检测方法可包括如下步骤S21至S32。
S21、将第一测试画面、第二测试画面、工作画面存储至显示装置的存储单元中。
也就是说,在显示第一测试画面之前,工作人员将第一测试画面、第二测试画面、工作画面储存至显示装置的存储单元中。例如,将将第一测试画面、第二测试画面、工作画面下载到显示装置的存储单元中。
需要说明的是,对第二测试画面、工作画面的存储也可延后,只要对第二测试画面的存储在显示第二测试画面之前进行即可,而对工作画面的存储在显示工作画面之前进行即可。
应当理解,显示装置也可以在获取第一测试画面的显示指令的同时获取第一测试画面、获取第二测试画面的显示指令的同时获取第二测试画面、以及获取工作画面显示指令的同时获取工作画面。
S22、向显示装置发送第一指令,以使显示装置的所有子显示屏均显示第一测试画面。
也就是说,向显示装置发送第一指令,使得显示装置的所有子显示屏在同一时刻均显示同一画面,即第一测试画面。
进一步的,向显示装置发送第一指令具体可以为通过基站向显示装置发送第一指令。
例如,可以是工作人员控制基站,以无线的方式向基站发送控制指令,使得基站向显示装置发送第一指令。具体的,基站可以是Lora基站等。
S231、根据第一测试画面的显示情况,判断是否所有子显示屏的显示灯均正常发光。
S232、若至少一个子显示屏的至少一个显示灯发光异常,则使用备用显示灯替换发光异常的显示灯。
具体地,每个子显示屏可包括多个显示灯,每个显示灯可以为一个LED灯珠,可以通过检测每个显示屏显示第一测试画面时各显示灯的发光亮度,并计算各显示灯的发光亮度与预定亮度之间的差异来判断各显示灯是否发光异常。例如,所述预定亮度可以为显示预定画面(例如,第一测试画面或第二测试画面)时,显示灯应有的发光亮 度,如果显示灯的发光亮度与预定亮度之间的差异大于第三预定值,则可看作该显示灯发光异常。
应当理解,如果子显示屏持续显示同一画面,子显示屏的各显示灯应当分别持续具有相对稳定的发光亮度,因此,也可以通过检测每个显示灯的发光亮度、并检测其随时间的变化来判断该显示灯是否发光异常,如果该显示灯的发光亮度随时间变化的最大幅度大于第四预定值,则可看作该显示灯发光异常。
上述第三预定值和第四预定值均可根据需要进行设定,本公开不进行具体限定。例如,人眼能够识别的显示灯的发光亮度与预定亮度之间的最小差异可设定为上述第三预定值,人眼能够识别的显示灯的发光亮度随时间变化的最小幅度可设定为上述第四预定值。
如果某子显示屏存在发光异常的显示灯,则可先使用备用显示灯替换发光异常的显示灯,而不直接替换子显示屏,从而可降低成本。
S241、根据第一测试画面的显示情况,判断是否所有子显示屏均符合显示标准。
该步骤的细节可参照上述步骤S12的相关描述,此处不再赘述。
S242、若至少一个子显示屏不符合显示标准,则对不符合显示标准的子显示屏进行第一复位操作,并使进行了第一复位操作的子显示屏重新显示第一测试画面。
该步骤的细节可参照上述步骤S13的相关描述,此处不再赘述。
S25、根据第一测试画面的显示情况,判断重新显示第一测试画面的子显示屏是否符合显示标准。
该步骤的细节可参照上述步骤S14的相关描述,此处不再赘述。
S26、若重新显示第一测试画面的子显示屏仍不符合显示标准,则使用备用子显示屏替换仍不符合显示标准的子显示屏。
即,若进行第一复位操作后,子显示屏仍然不能正常显示,则认为子显示屏已经损坏了,从而可将该子显示屏替换掉。
在一些实施方式中,开始显示第一测试画面的时间比开始显示工作画面(如步骤S31中的工作画面)的时间早13分钟至17分钟。
例如,开始显示第一测试画面的时间可比开始显示工作画面(如 步骤S31中的工作画面)的时间早15分钟。
即,可在正式开始工作前的13分钟至17分钟(如15分钟)开始进行上述步骤S21至S26。这样的时间间隔比较合适,一方面其距离正式开始工作的时间很短,通常在这样短时间内显示装置不容易出现新问题,同时又足够进行复位、替换等操作。
该阶段的检测主要针对显示装置由于搬运、安装或者之前放置的时间过长而造成的LED灯珠或者子显示屏的损坏。
S27、向显示装置发送第二指令,以使显示屏的所有子显示屏均显示第二测试画面。
例如,可通过基站将第二指令发送至显示装置,使得显示装置的所有子显示屏在同一时刻均显示同一画面,即第二测试画面。
S281、根据第二测试画面的显示情况,判断是否所有子显示屏的显示灯均正常发光。
也就是说,在步骤S21至S26后,再一次检测各子显示屏的LED灯珠是否发光异常,以防止之前的检测过程中显示灯的损坏。
S282、若至少一个子显示屏的至少一个显示灯发光异常,则使用备用显示灯替换发光异常的显示灯。
步骤S281和S282的细节可参照上述步骤S231和S232的相关描述,此处不再赘述。
S291、根据第二测试画面的显示情况,判断是否所有子显示屏均符合显示标准。
例如,可通过比较各子显示屏的实际显示时刻与第二测试画面的预定显示时刻来判断各子显示屏是否符合显示标准,如果子显示屏的实际显示时刻与第二测试画面的预定显示时刻之间的差值大于第一预定值,则可看作该子显示屏不符合显示标准。当然,也可通过比较各子显示屏的实际显示画面属性与第二测试画面的预定属性来判断各字显示屏是否符合标准,如果子显示屏的实际显示画面属性与第二测试画面的预定属性之间的差异大于第二预定值,例如,如果子显示屏的实际显示画面颜色与第二测试画面的预定颜色之间的色差大于第二预定值,则判断该子显示屏不符合显示标准。
例如,可以事先统计人眼观察认为各子显示屏在同一时刻显示第二测试画面时各子显示屏的实际显示时刻之间的差值,并将这些差值的均值作为第一预定值,如果子显示屏的实际显示时刻与第二测试画面的预定显示时刻之间的差值大于该第一预定值,则可看作该子显示屏不符合显示标准;还可以事先统计人眼观察认为各子显示屏在同一时刻显示第二测试画面时各子显示屏的实际显示画面属性之间的差异,并将这些差异的均值作为第二预定值,如果子显示屏的实际显示画面属性与第二测试画面的预定属性之间的差异大于该第二预定值,则判断该子显示屏不符合显示标准。
应当理解,如果子显示屏不生成包含其实际显示时刻和实际显示画面属性(例如颜色)等相关信息的信号,则可能是该子显示屏无法进行显示,因此该子显示屏也不符合显示标准。
另外,还可以考虑各子显示屏应当显示的画面尺寸,如果子显示屏实际显示的画面尺寸小于其应当显示的画面尺寸,则该子显示屏没有完全显示第二测试画面,不符合显示标准。
当然,可以结合上述一种或多种因素来判断子显示屏是否符合显示标准,本公开对此不进行具体限定。
S292、若至少一个子显示屏不符合显示标准,则对不符合显示标准的子显示屏进行第二复位操作,并使进行了第二复位操作的子显示屏重新显示第二测试画面。
对不符合显示标准的子显示屏进行第二复位操作也可相当于对该子显示屏进行“热启动”。具体的,本公开不限定对不符合显示标准的子显示屏进行第二复位操作的具体方式,例如,可以通过显示装置的控制器对不符合显示标准的子显示屏进行第二复位操作,也可以通过显示装置显示提示信息提示工作人员按下与不符合显示标准的子显示屏对应的复位键来对不符合显示标准的子显示屏进行第二复位操作。
需要说明的是,步骤S22至S26中已经对损坏的子显示屏进行了替换,因此,此处子显示屏显示异常(即不符合显示标准)的原因要是子显示屏死机或者卡顿等造成的,仅需要对显示异常的子显示屏 进行第二复位操作即可,而可不替换该子显示屏。
S30、向显示装置发送第三指令,以使所有子显示屏进入显示预备阶段。
“显示预备阶段”具体是指所有的子显示屏等待显示工作画面的阶段。
在一些实施方式中,开始显示第二测试画面的时间比开始显示工作画面(如步骤S31中的工作画面)的时间早1分钟至2分钟。例如,开始显示第二测试画面的时间可比开始显示工作画面(如步骤S31中的工作画面)的时间早1分钟。
该阶段的检测主要针对在步骤S22至S26中对子显示屏的误触或者误操作而造成的子显示屏的显示不正常的情况。
本公开中,第一指令和第二指令可相同或不同,相应地,第一测试画面和第二测试画面可相同或不同,此外,第一复位操作和第二复位操作可相同或不同,本公开不进行具体限定。
也就是说,所述第二测试画面也可能为特定颜色的纯色画面,例如,可能为白色、黑色、蓝色、绿色、红色、或黄色的纯色画面,第二测试画面的颜色可与第一测试画面的颜色相同或不同。
S31、向显示装置发送第四指令,以使所有子显示屏在多个工作阶段中依次显示多个工作画面。
此处的工作画面是指在正式工作中所要显示的画面(比如显示表演需要的工作画面)。
S32、若在一工作阶段中,至少一个子显示屏显示异常(即,不符合显示标准),则对显示异常的子显示屏进行第三复位操作,并使进行了第三复位操作的子显示屏在下一工作阶段中显示相应的工作画面。
具体地,在显示装置显示工作画面时,各子显示屏应当分别显示预定画面,如果子显示屏不能正常显示预定画面,则该子显示屏显示异常。
例如,各子显示屏显示工作画面期间,可间隔(例如以预定间隔)生成包含其显示预定画面的实际显示时刻和实际显示的预定画面 的属性(例如颜色)等相关信息的信号,可通过分析该信号来判断子显示屏是否显示异常。
例如,可通过比较各子显示屏显示预定画面的实际显示时刻与显示该预定画面的预定显示时刻来判断各子显示屏是否显示异常,如果子显示屏显示预定画面的实际显示时刻与显示该预定画面的预定显示时刻之间的差值大于第五预定值,则可看作该子显示屏显示异常。当然,也可通过比较各子显示屏实际显示的预定画面的属性与该预定画面的预定属性来判断各字显示屏是否显示异常,如果子显示屏实际显示的预定画面的属性与该预定画面的预定属性之间的差异大于第六预定值,例如,如果子显示屏实际显示的预定画面的颜色与该预定画面的预定颜色之间的色差大于第六预定值,则判断该子显示屏显示异常。
例如,可以事先统计人眼观察认为子显示屏显示预定画面的实际显示时刻与显示该预定画面的预定显示时刻为同一时刻时子显示屏显示预定画面的实际显示时刻与显示该预定画面的预定显示时刻之间的差值,并将这些差值的均值作为第五预定值,如果子显示屏显示预定画面的实际显示时刻与显示该预定画面的预定显示时刻之间的差值大于该第五预定值,则可看作该子显示屏显示异常;还可以事先统计人眼观察认为子显示屏实际显示的预定画面的属性与该预定画面的预定属性相同时子显示屏实际显示的预定画面的属性与该预定画面的预定属性之间的差异,并将这些差异的均值作为第六预定值,如果子显示屏实际显示的预定画面的属性与该预定画面的预定属性之间的差异大于该第六预定值,则判断该子显示屏显示异常。
应当理解,如果子显示屏不以预定间隔生成包含其显示预定画面的实际显示时刻和实际显示的预定画面的属性(例如颜色)等相关信息的信号,则可能是该子显示屏无法进行显示,因此该子显示屏也可被判断为显示异常。
另外,还可以考虑各子显示屏应当显示的画面尺寸,如果子显示屏实际显示的画面尺寸小于其应当显示的画面尺寸,则该子显示屏没有完全显示预定画面,显示异常。
当然,可以结合上述一种、或多种因素来判断子显示屏是否显示异常,本公开对此不进行具体限定。
当发现在当前工作阶段中有显示异常的子显示屏,则可在当前工作阶段快结束的时候对显示异常的子显示屏进行第三复位操作,使得该子显示屏在下一工作阶段可以正常显示,即,使得该子显示屏在下一工作阶段显示相应的工作画面。
本公开中,第三复位操作可与第一复位操作和/或第二复位操作相同,对子显示屏进行第三复位操作也可相当于对该子显示屏进行“热启动”,本公开不限定对子显示屏进行第三复位操作的具体方式,例如,可以通过显示装置的控制器对子显示屏进行第三复位操作,也可以通过显示装置显示提示信息提示工作人员按下与子显示屏对应的复位键来对子显示屏进行第三复位操作。
具体的,对于子显示屏数量较多的显示装置,可以使不同子显示屏对应不同的代码(如0001、0010等),这样可以通过向显示装置输入不同的代码来控制不同的子显示屏进行操作,例如进行显示或复位。
需要说明的是,步骤S31和S32是在显示装置正在显示工作画面时对显示装置进行检测。该阶段的检测主要针对显示装置在显示工作画面时临时出现的子显示屏显示异常,如子显示屏死机等。
应当说明的是,在本文中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括要素的过程、方法、物品或者设备中还存在另外的相同要素。
依照本公开的实施例如上文所述,这些实施例并没有详尽叙述 所有的细节,也不限制该公开仅为所述的具体实施例。显然,根据以上描述,可作很多的修改和变化。本说明书选取并具体描述这些实施例是为了更好地解释本公开的原理和实际应用,从而使所属技术领域技术人员能很好地利用本公开以及在本公开基础上的修改。本公开仅受权利要求书及其全部范围和等效物的限制。
