Description

显示屏显示调整方法及系统 技术领域
本申请涉及显示屏技术,尤其涉及一种显示屏显示调整方法及系统。
背景技术
LED(light emitting diode,发光二极管)显示屏通常包括多个LED模组,每个LED模组中设有至少一个LED灯珠。不同生产批次的LED灯珠的波长、亮度可能不一致,因而在显示时,构成一个LED显示屏的各个LED模组之间可能有色差,导致该LED显示屏的显示中可能出现用户可察觉的色差。为了降低LED显示屏的色差,需要对显示屏的显示进行调整。
在相关技术中,可以获取LED显示屏的配置文件,配置文件中包含该LED显示屏上的各个灯珠的批次信息。可以根据批次信息和该LED显示屏已使用的时间,计算得到各个灯珠的校正系数,并利用得到的校正系数调整该LED显示屏的亮色度。然而,该校正系数是根据理论亮度衰减曲线推算出来的。实际的显示屏亮度衰减有很多影响因素,如电源电压、环境温度湿度等。因此,利用由理论推算得到的校正系数进行的调整的效果并不佳。
发明内容
根据本申请的第一方面,提供一种显示屏显示调整方法,所述显示屏包括多个LED模组,所述方法包括:采集各LED模组在设定灰阶值下进行显示时的显示参数值,所述设定灰阶值为预设灰阶范围中的一个灰阶值;根据所采集的各LED模组在设定灰阶值下的显示参数值,确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数;根据各LED模组在设定灰阶值下的相应校正系数,调整所述显示屏在设定灰阶值下的显示。
根据本申请的第二方面,提供一种显示屏显示调整系统,所述显示屏包括多个LED模组,所述系统包括亮色度采集设备和显示控制设备,其中,所述亮色度采集设备用于采集各LED模组在设定灰阶值下进行显示时的显示参数值,所述设定灰阶值为预设灰阶范围中 的一个灰阶值;所述显示控制设备用于根据所述亮色度采集设备采集的各LED模组在设定灰阶值下的显示参数值,确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数,并根据相应校正系数校正各LED模组在设定灰阶值下的显示。
根据本申请的实施例,通过对显示屏的每一灰阶进行单独的色差调整,可以实现在每一灰阶下显示屏亮色度一致。此外,由实际采集得到的显示参数值计算得到校正系数,考虑到了各种实际环境因素的影响,因而得到的校正系数更加准确,基于校正系数的调整效果更佳。

图1为根据本申请一示例性实施例的一种显示屏显示调整方法的流程图。该显示屏包括多个LED模组,每个LED模组中设有多个LED灯珠。如图1所示,该显示屏显示调整方法可以包括步骤101~103。
在步骤101,可以采集各LED模组在设定灰阶值下进行显示时的显示参数值,所述设定灰阶值为预设灰阶范围中的一个灰阶值。
在一实施例中,可以通过显示控制设备控制所述显示屏在设定灰阶值下显示指定颜色的画面,并由亮色度采集设备采集显示屏中各LED模组在设定灰阶值下显示指定颜色的画面时的显示参数值。
根据显示屏的显示能力,上述预设灰阶范围可以为0~255或0~1023。上述指定颜色的画面可以包括红色、绿色、蓝色以及白色的画面,从而可以采集每个LED模组在设定灰阶值下分别显示红、绿、蓝、白四种颜色的画面时的显示参数值。显示参数可以是色域信息,至少包括亮度和色度。
在步骤102,可以根据所采集的各LED模组在设定灰阶值下的显示参数值,确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数。
在一实施例中,显示控制设备可以根据所采集的各LED模组在设定灰阶值下的显示参数值,确定显示屏在设定灰阶值下的目标显示参数值。然后,显示控制设备可以针对每一LED模组,根据所采集的该LED模组在设定灰阶值下的显示参数值和所确定的显示屏在设定灰阶值下的目标显示参数值,确定该LED模组在设定灰阶值下的校正系数。
例如,显示控制设备可以根据所采集的每个LED模组在设定灰阶值下分别显示红色、绿色、蓝色、白色的画面时的显示参数值,通过相关技术计算得到整个显示屏在设定灰阶值下分别显示红色、绿色、蓝色、白色画面时的目标显示参数值(即,整个显示屏的公共色域信息)。
在一实施例中,针对每一LED模组,显示控制设备可以根据以下公式确定该LED模组在设定灰阶值下的校正系数:

其中,R orig,G orig,B orig分别表示所采集的该LED模组在设定灰阶值下分别显示红色、绿色、蓝色画面时的亮度/色度值,R tar,G tar,B tar分别表示上述计算得到的整个显示屏在 设定灰阶值下分别显示红色、绿色、蓝色画面时的目标亮度/目标色度值,
Figure PCTCN2020076460-appb-000002
表示该LED模组在设定灰阶值下的校正系数的矩阵。
在步骤103,可以根据各LED模组在设定灰阶值下的相应校正系数,调整所述显示屏在设定灰阶值下的显示。
在一实施例中,显示控制设备可以根据各LED模组在设定灰阶值下的相应校正系数,校正各LED模组在设定灰阶值下的显示,从而调整整个显示屏在设定灰阶值下的显示。
在一实施例中,在执行步骤103之后,还可以验证各LED模组在设定灰阶值下的相应校正系数是否准确。例如,可以控制亮色度采集设备重新采集经校正的各LED模组在设定灰阶值下进行显示时的显示参数值。显示控制设备可以针对每一LED模组,计算重新采集的经校正的该LED模组在设定灰阶值下的显示参数值与显示屏在设定灰阶值下的目标显示参数值之间的差值,并判断该差值是否在预设误差范围内。若针对任一LED模组判定相应的差值不在预设误差范围内,则可以确定各LED模组在设定灰阶值下的相应校正系数不准确;否则,可以确定各LED模组在设定灰阶值下的相应校正系数准确。
若确定各LED模组在设定灰阶值下的相应校正系数准确,则可以检查设定灰阶值是否为预设灰阶范围中最后一个未被遍历的灰阶值,当检查结果为否时,将预设灰阶范围中下一个灰阶值作为设定灰阶值,返回执行步骤101~103。另一方面,若确定各LED模组在设定灰阶值下的相应校正系数不准确,则根据重新采集的经校正的各LED模组在设定灰阶值下的显示参数值,重新确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数,并根据重新确定的相应校正系数重新调整所述显示屏在设定灰阶值下的显示,以实现闭环调整,使得显示屏的色差进一步缩小,达到良好的调整效果。
需要说明的是,由于最高灰阶是影响显示屏色差的主要因素,因此在根据上述步骤101至步骤103进行调整时,可以按照从高灰阶值到低灰阶值的顺序调整。
在本申请实施例中,通过采集各LED模组在设定灰阶值(为预设灰阶范围中的一个灰阶值)下进行显示时的显示参数值,并根据各LED模组在设定灰阶值下的显示参数值确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数,进而根据各LED模组在设定灰阶值下的相应校正系数调整所述显示屏在设定灰阶值下的显示。
基于上述描述可知,通过对显示屏的每一灰阶进行单独的色差调整,可以实现在每一 灰阶下显示屏亮色度一致。此外,由实际采集得到的显示参数值计算得到校正系数,考虑到了各种实际环境因素的影响,因而得到的校正系数更加准确,基于校正系数的调整效果更佳。
需要说明的是,上述方法也适用于多个存在色差的显示屏。具体地,可以采集每个显示屏的显示参数值,根据所采集的显示参数值计算每个显示屏的校正系数,并根据所计算的校正系数调整相应显示屏的显示。
图2为根据本申请一示例性实施例的一种显示屏显示调整系统的示意图。参见图2,显示屏230可以包括多个LED模组,该系统可以包括亮色度采集设备210和显示控制设备220。

显示控制设备220可以根据亮色度采集设备210采集的各LED模组在设定灰阶值下的显示参数值,确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数,并根据相应校正系数校正各LED模组在设定灰阶值下的显示,从而调整显示屏230在设定灰阶值下的显示。
在一实施例中,显示控制设备220可以控制显示屏230在设定灰阶值下显示指定颜色的画面。亮色度采集设备210可以采集显示屏230中各LED模组在设定灰阶值下显示所述指定颜色的画面时的显示参数值。
在一实施例中,显示控制设备220可以根据亮色度采集设备210所采集的各LED模组在设定灰阶值下的显示参数值,确定显示屏230在设定灰阶值下的目标显示参数值。然后,针对每一LED模组,显示控制设备220可以根据亮色度采集设备210所采集的该LED模组在设定灰阶值下的显示参数值和显示屏230在设定灰阶值下的目标显示参数值,确定用于校正该LED模组在设定灰阶值下的显示的校正系数。
在一实施例中,显示控制设备220可以在根据相应校正系数校正显示屏230的各LED模组在设定灰阶值下的显示之后,验证各LED模组在设定灰阶值下的相应校正系数是否准确。例如,显示控制设备220可以控制亮色度采集设备210重新采集经校正的各LED模组在设定灰阶值下进行显示时的显示参数值。显示控制设备220可以针对每一LED模组,计算亮色度采集设备210重新采集的该LED模组在设定灰阶值下的显示参数值与显示屏230 在设定灰阶值下的目标显示参数值之间的差值,并判断该差值是否在预设误差范围内。若针对任一LED模组判定相应的差值不在预设误差范围内,则显示控制设备220可以确定各LED模组在设定灰阶值下的相应校正系数不准确;否则,显示控制设备220可以确定各LED模组在设定灰阶值下的相应校正系数准确。
若确定各LED模组在设定灰阶值下的相应校正系数准确,则显示控制设备220可以检查设定灰阶值是否为预设灰阶范围中最后一个未被遍历的灰阶值,当检查结果为否时,将预设灰阶范围中下一个灰阶值作为设定灰阶值。若确定各LED模组在设定灰阶值下的相应校正系数不准确,则显示控制设备220可以根据亮色度采集设备210重新采集的经校正的各LED模组在设定灰阶值下的显示参数值,重新确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数,并根据重新确定的相应校正系数重新校正各LED模组在设定灰阶值下的显示,以实现闭环调整。

    所述显示控制设备还用于控制所述显示屏在设定灰阶值下显示指定颜色的画面;
    所述亮色度采集设备用于采集所述显示屏中各LED模组在设定灰阶值下显示所述指定颜色的画面时的显示参数值。
  9. 根据权利要求7所述的系统,其中,
    所述显示控制设备用于:根据所述亮色度采集设备采集的各LED模组在设定灰阶值下的显示参数值,确定所述显示屏在设定灰阶值下的目标显示参数值;针对每一LED模组,根据所述亮色度采集设备采集的该LED模组在设定灰阶值下的显示参数值和所述显示屏在设定灰阶值下的目标显示参数值,确定用于校正该LED模组在设定灰阶值下的显示的校正系数。
  10. 根据权利要求7至9中任一项所述的系统,其中,所述显示控制设备还用于:在根据相应校正系数校正各LED模组在设定灰阶值下的显示之后,
    控制所述亮色度采集设备重新采集经校正的各LED模组在设定灰阶值下进行显示时的显示参数值;
    针对每一LED模组,计算所述亮色度采集设备重新采集的该LED模组在设定灰阶值下的显示参数值与所述显示屏在设定灰阶值下的目标显示参数值之间的差值,并判断该差值是否在预设误差范围内;
    若针对任一LED模组所述差值不在预设误差范围内,则确定各LED模组在设定灰阶值下的相应校正系数不准确;
    若针对每一LED模组所述差值都在预设误差范围内,则确定各LED模组在设定灰阶值下的相应校正系数准确。
  11. 根据权利要求10所述的系统,其中,所述显示控制设备还用于:
    若确定各LED模组在设定灰阶值下的相应校正系数准确,则检查设定灰阶值是否为预设灰阶范围中最后一个未被遍历的灰阶值,当检查结果为否时,将所述预设灰阶范围中下一个灰阶值作为设定灰阶值;
    若确定各LED模组在设定灰阶值下的相应校正系数不准确,则根据所述亮色度采集设备重新采集的经校正的各LED模组在设定灰阶值下的显示参数值,重新确定分别用于校正各LED模组在设定灰阶值下的显示的相应校正系数,并根据重新确定的相应校正系数重新校正各LED模组在设定灰阶值下的显示。
