Since white absorbs light little, therefore, by detecting the brightness of the ambient light reflected by the standard whiteboard, Can improve the detection accuracy of environmental brightness.
- the purpose of detecting the environmental brightness is to obtain the parameters of natural light with the same brightness, because the human eye will automatically adjust the pupil size according to the size of the environmental brightness so that the luminous flux entering the eye is in a range that is harmless to the human eye. Therefore, the brightness of natural light with the same brightness and its various wavelength components, especially the blue light component, can be used as the best standard for display. If the average brightness and the damage index of the blue component displayed at this time are close to the brightness of natural light, the luminous flux displayed in the eye is harmless to the human eye and feels comfortable.

Therefore, the natural optical environment where the display device is located can be used as the adjustment standard. Allow the floating range to adjust the corresponding display parameters to approach this standard, and achieve the effect that the displayed image is not harmful to the human eye and feels comfortable.
- the brightness of the intermediate gray scales is close to the ambient brightness, which can make the human eye feel more comfortable when perceiving the picture. In this way, the pupils of the human eyes are not easily dilated, which can reduce the passage of the pupils to the fundus retina.

- the first implementation method is the adjustment method based on hardware. Since the gray scale can indicate the brightness level of the display device, the backlight brightness of the display device can determine the brightness of the maximum gray scale, that is, the maximum brightness of the display. If the brightness of the gray scale is determined, the brightness of other gray scales can also be determined correspondingly according to the number of gray scales of the display device. Therefore, to meet the preset condition that the brightness of the intermediate gray scale is close to the ambient brightness, it can be first determined that if the brightness of the intermediate gray scale is close to the environmental brightness, the corresponding brightness of the maximum gray scale of the display device should be Then, it can be determined what the first backlight driving parameter corresponding to the maximum gray-scale brightness corresponding to the preset condition should be.

- the ratio of the ambient brightness to the brightness before the adjustment of the intermediate gray scale even if the brightness of the intermediate gray scale is close to the adjustment ratio of the environmental brightness, correspondingly, the second brightness that should be reached after the adjustment of the target gray scale is also the target
- the target gray scale can be any gray scale of the display device, that is, it can determine how much brightness all the gray scales of the display device should be after adjustment, that is, the second brightness, and then determine the original brightness corresponding to the second brightness of all gray scales.
- the grayscale value of the grayscale That is to say, all gray levels can be calculated in advance, and then when displaying, use the calculated brightness of the original gray level to display, so that when the environmental brightness does not change for a long time, the calculation time can be saved and the display can be improved. efficient.
- the target gray scale can also be any gray scale to be displayed, that is, which gray scale the display device needs to display, and the original gray scale corresponding to the second brightness of the gray scale is calculated in real time, because the environmental brightness may change more. Therefore, the ratio of the ambient brightness to the brightness before the adjustment of the intermediate gray scale is constantly changing. Therefore, the gray scale to be displayed can be calculated in real time, thereby improving the display efficiency.
- the brightness of the maximum gray scale of a display device (such as a television) is 255

- L max is about 230nit.
- the highest brightness of general TV sets is about 350nit ⁇ 450nit. Through this adjustment method, The amount of blue light radiation can be reduced by 1/3 to 1/2.
- Step 103 Adjust the brightness of at least part of the gray scale of the display device according to the adjustment parameter.
- step 102 respectively correspond to the two implementation manners in step 102, and this step also has two implementation manners.
- step 103 can be implemented through the following steps:
- the backlight module of the display device is driven according to the first backlight driving parameter, so that the difference between the brightness of the middle gray scale and the ambient brightness is smaller than the preset brightness value.
- the backlight mode of the display device is driven according to the first backlight driving parameter.
- the group can make the maximum gray-scale brightness equal to the brightness that should be achieved when the preset conditions are met, thereby indirectly making the brightness of the intermediate gray-scale close to the ambient brightness and the preset conditions are met, and other gray levels are adjusted accordingly in the same proportion.
- step 103 can be implemented through the following steps:
- the display is performed according to the brightness of the original gray scale. Specifically, when the target gray scale is included in the display data of the picture to be displayed, the display is performed according to the brightness of the original gray scale.
- the display device may first prepare all the display data of the picture, which may include the gray scale corresponding to each pixel in the picture. If the display data of the picture to be displayed includes the target gray scale, It indicates that the display condition of the target gray scale is satisfied, and the display device can display according to the brightness of the original gray scale corresponding to the second brightness of the target gray scale. If the target gray scale is an intermediate gray scale, the brightness of the intermediate gray scale will be close to the ambient brightness during display.
- the grayscale brightness can be adjusted and fixed according to the fixed environmental brightness before leaving the factory. If the environmental brightness of the display environment is not fixed, the grayscale brightness can be automatically adjusted during the display process according to the detection data of the environmental brightness detection device, which is not specifically limited in the embodiment of the present disclosure.
- step 103 may be implemented by the following steps: obtaining the blue light exposure value of the display device, which is used to characterize the degree of radiation damage caused by the blue light of the display device to human eyes; and according to the adjustment parameters and the blue light exposure value, The brightness of at least part of the gray scale of the display device is adjusted so that the blue light exposure value is less than the preset standard value.
- the preset standard value can be 1W/m 2 .

Therefore, when the display brightness is adjusted, the blue light exposure value of the display device can be controlled to always meet the above standards, thereby avoiding blue light damage to the human eyes.
- the blue light exposure value of the display device can be obtained by performing a radiance spectrum scan in advance, and then weighted by the following formula, and stored in the display device.
- 300nm and 700nm are the waveband boundary values of the scanning spectrum, that is, spectral scanning is performed on the wavebands greater than or equal to 300nm and less than or equal to 700nm.

如今，人们对于显示装置带给人眼的伤害越来越重视，因此，很多显示装置采用降低色温、配置护眼模式等方式，以减少对人眼伤害较大的主要光线成分，也即蓝光，从而降低显示装置对人眼的伤害。
但是，在显示装置发射出的蓝光中，真正对视网膜形成伤害的是通过瞳孔，到达眼底视网膜的蓝光，因此，仅仅降低蓝光的发射量并不能保证到达眼底蓝光的辐射量能够降低。例如，在较暗的环境下，人眼瞳孔扩张，入光量与瞳孔直径的平方成正比，同样的画面，到达眼底的蓝光辐射量就远远高于办公环境下人眼瞳孔直径较小时的蓝光辐射量，对人眼的伤害也大得多。

上述说明仅是本公开技术方案的概述，为了能够更清楚了解本公开的技术手段，而可依照说明书的内容予以实施，并且为了让本公开的上述和其它目的、特征和优点能够更明显易懂，以下特举本公开的具体实施方式。
附图简述
为了更清楚地说明本公开实施例或相关技术中的技术方案，下面将对实施例或相关技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

详细描述
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
参照图1示意性地示出了一种显示参数调整方法的流程图，该方法包括以下步骤：
步骤101：检测环境亮度。
在本公开实施例中，显示装置可安装环境亮度检测装置，例如亮度传感 器等，从而显示装置可以通过亮度传感器检测显示环境的环境亮度。在实际应用中，环境亮度检测装置可以包括一块标准白板，用于将大量的环境光反射至亮度传感器上，由于白色对光线的吸收很少，因此，通过检测标准白板反射的环境光的亮度，可以提高对环境亮度的检测准确度。
检测环境亮度的目的是获取同亮度自然光的参数，因为人眼会根据环境亮度的大小自动调节瞳孔大小使入眼的光通量处于对人眼无害的范围内。所以，同亮度自然光亮度及其各波长分量，尤其是蓝光分量可以作为显示的最佳标准。如果这时显示的平均亮度及蓝光分量的伤害指数大小与该亮度自然光接近，则入眼显示光通量对人眼无害且感觉舒适。
步骤102：确定预设条件对应的显示装置的调整参量；预设条件包括显示装置的中间灰阶的亮度与环境亮度之间的差值小于或等于预设亮度值。
在本公开实施例中，预设条件可以表示显示装置的中间灰阶的亮度趋近于环境亮度。显示装置可以确定，若将中间灰阶的亮度趋近于环境亮度，则显示装置对应的调整参量应该是多少。之后若按照该调整参量进行灰阶亮度的调整，便能够使中间灰阶的亮度趋近于环境亮度。
可选地，该预设亮度值可以大于或等于环境亮度的0.2倍，且小于或等于环境亮度的1.6倍。在实际应用中，还可以根据显示画面的不同，也即不同的显示需求，调整该预设亮度值，本公开实施例对此不作具体限定。例如，对于国画等绘画作品的画面，该预设亮度值可以大于或等于所述环境亮度的0.2倍，且小于或等于所述环境亮度的0.4倍，对于视频、摄影等画面，该预设亮度值可以大于或等于所述环境亮度的0.8倍，且小于或等于所述环境亮度的1.6倍。
可选地，预设条件可以为显示装置的中间灰阶的亮度与环境亮度相等。即显示装置的中间灰阶的亮度与环境亮度之间的差值可以等于零。
由于中间灰阶画面代表人眼感知亮度的中间点，也是人眼对当前环境平均亮度适应后的生理平衡点。显示画面的中间灰阶亮度与人眼在此环境下的适应生理平衡点一致时，对画面的感知就更舒适自然一些，因此，可以以显示装置所在的自然光学环境为调整标准，以适当的允许浮动范围来调整相应的显示参数以趋近这个标准，达到显示图像对人眼无伤害且感觉舒适的效果。通过对灰阶亮度进行调整，使得中间灰阶的亮度趋近于环境亮度，从而能够使人眼感知画面时更加舒适，这样，人眼瞳孔便不易受激扩张，进而可以降低通过瞳孔到达眼底视网膜的蓝光辐射量，从而降低了蓝光对人眼的伤害。
具体地，本步骤可以通过下述两种方式实现：
第一种实现方式，包括以下步骤：
确定预设条件对应的显示装置的最大灰阶的亮度；根据预设的灰阶亮度与背光驱动参数之间的第一对应关系，确定最大灰阶的亮度对应的第一背光 驱动参数，并将第一背光驱动参数作为调整参量。
第一种实现方式也即基于硬件的调整方式，由于灰阶可以表示显示装置的亮度的级别，因此，显示装置的背光亮度可以决定最大灰阶的亮度，也即是决定显示的最大亮度，最大灰阶的亮度若确定，则根据显示装置的灰阶数，其他灰阶的亮度也可相应确定。因此，若要满足中间灰阶的亮度趋近于环境亮度的预设条件，则可以首先确定，若将中间灰阶的亮度趋近于环境亮度，则显示装置的最大灰阶的对应亮度应该是多少，然后可以确定预设条件对应的最大灰阶亮度所对应的第一背光驱动参数应该是多少，之后若按照该第一背光驱动参数驱动显示装置的背光模组，便能够使最大灰阶亮度等于应该达到的亮度，从而间接使中间灰阶的亮度趋近于环境亮度，其他灰阶也相应的同比例调整。
其中，可以事先预存不同的灰阶亮度与背光驱动参数之间的第一对应关系，当需要使最大灰阶亮度达到某个亮度时，便可通过查表的方式确定使最大灰阶亮度达到该亮度的背光驱动参数。根据环境亮度检测装置检测到的亮度电学参数(通常可以是电压或电流)，经过模拟信号/数字信号(Analogue/Digital,A/D)转换后可以变为数字信号形式的亮度参数，相应的，第一对应关系种的灰阶亮度可以通过数字信号形式的亮度参数表示。然后可以根据该第一对应关系，调整显示装置的背光亮度，以使中间灰阶的亮度与检测到的环境亮度一致。采用调整背光亮度的方式，可以实现显示装置所有灰阶的亮度调整。
其中，背光模组的驱动机理不同时，背光驱动参数也会有所不同。例如，当背光模组的驱动类型为电压驱动时，背光驱动参数为背光模组的驱动电压信号的占空比。对于电压驱动型的背光模组，可以通过调整脉冲宽度调制(Pulse Width Modulation,PWM)的占空比来达到不同的背光亮度，也即背光驱动参数可以是背光驱动电压信号的占空比。当背光模组的驱动类型为电流驱动时，背光驱动参数为背光模组的驱动电流。对于电流驱动型的背光模组，则可以通过调整背光驱动电流的大小来达到不同的背光亮度，也即背光驱动参数可以是背光驱动电流。对其他类型的显示设备，也可根据其发光机理的不同而采用不同的措施。
第二种实现方式，包括以下步骤：
确定环境亮度与中间灰阶调整前的亮度的比值，得到显示装置的调整比例；确定目标灰阶调整前的第一亮度分别与调整比例的乘积，得到目标灰阶的第二亮度；目标灰阶为显示装置的任一灰阶，或者待显示的任一灰阶；根据预设的灰阶与调整前的亮度之间的第二对应关系，确定第二亮度对应的原始灰阶，并将原始灰阶作为调整参量。
第二种实现方式也即基于软件的调整方式，即升高或降低欲显示灰阶的 灰阶值。具体地，也即是通过确定每个目标灰阶调整后的亮度对应的是哪个调整前的灰阶，进而在需要显示目标灰阶时，按照对应的调整前的灰阶的亮度进行显示即可。例如，目标灰阶L
134调整后的亮度x对应的是原先调整前的灰阶L
150，也即灰阶L
150原先对应的亮度是x，则当需要显示目标灰阶L
134时，可以按照灰阶L
150的亮度x进行显示，即可使目标灰阶L
134的亮度为x。其中，环境亮度与中间灰阶调整前的亮度的比值，也即使中间灰阶的亮度趋近于环境亮度的调整比例，相应的，目标灰阶的调整后应该达到的第二亮度也即是目标灰阶调整前的第一亮度分别与该调整比例的乘积，从而使得目标灰阶的亮度可以与中间灰阶的亮度同比例调整。
其中，目标灰阶可以为显示装置的任一灰阶，也即是可以确定显示装置所有的灰阶调整后应该是多少亮度，即第二亮度，然后确定所有灰阶的第二亮度对应的原始灰阶的灰阶值。也即是可以事先对所有灰阶进行计算，之后在显示时，利用计算出的原始灰阶的亮度进行显示即可，从而在环境亮度长时间不变的情况下，可以节省计算时间，提高显示效率。
当然，目标灰阶还可以是待显示的任一灰阶，也即是显示装置需要显示哪个灰阶，就实时计算出该灰阶的第二亮度对应的原始灰阶，因为环境亮度可能变化较快，因而环境亮度与中间灰阶调整前的亮度的比值也在不断变化，因此，可以对待显示灰阶进行实时计算，从而能够提高显示效率。
例如，在显示装置(如电视机)的最大灰阶为255的情况下，最大灰阶的亮度L
max与中间灰阶127的亮度满足关系：L
max＝L
127*(2γ)，其中，γ的取值与环境相关，比如在客厅环境下，γ值通常可采用2.2。当环境亮度为50nit(尼特)时，中间灰阶亮度L
127可以等于环境亮度50nit，则L
max约为230nit，而目前一般电视机的最高亮度在350nit～450nit左右，通过这种调整方式，蓝光辐射量可以降低1/3～1/2。
此外，在上述两种方式中，由于每个目标灰阶的亮度都同比例进行了调整，因此，对显示装置的对比度没有影响。
步骤103：根据调整参量，对显示装置的至少部分灰阶的亮度进行调整。
在本公开实施例中，分别对应于步骤102中的两种实现方式，本步骤也有两种实现方式。
对应步骤102中的第一种实现方式，步骤103可通过以下步骤实现：
按照第一背光驱动参数驱动显示装置的背光模组，以使中间灰阶的亮度与环境亮度之间的差值小于预设亮度值。
其中，由于第一背光驱动参数是将中间灰阶的亮度趋近于环境亮度的情况下，最大灰阶的亮度所对应的背光驱动参数，因此，按照第一背光驱动参数驱动显示装置的背光模组，可以使最大灰阶亮度等于预设条件满足的情况下应该达到的亮度，从而间接使中间灰阶的亮度趋近于环境亮度的预设条件 满足，其他灰阶也相应的同比例调整。
对应步骤102中的第二种实现方式，步骤103可通过以下步骤实现：
在满足目标灰阶的显示条件时，按照原始灰阶的亮度进行显示。具体地，当待显示的画面的显示数据中包括目标灰阶时，按照原始灰阶的亮度进行显示。
其中，在显示一个画面之前，显示装置首先可以准备好该画面的所有显示数据，其中便可以包括该画面中每个像素对应的灰阶，若待显示的画面的显示数据中包括目标灰阶，则说明满足目标灰阶的显示条件，进而显示装置可以按照目标灰阶第二亮度对应的原始灰阶的亮度进行显示。若目标灰阶为中间灰阶，则在显示时，中间灰阶的亮度即趋近于环境亮度。
需要说明的是，在实际应用中，可以根据显示装置的用途，决定是在显示装置出厂前调整灰阶亮度，还是在出厂后，根据环境亮度进行实时调整。如果显示环境固定，也即环境亮度固定，则在出厂前即可将根据固定的环境亮度，调整好各个灰阶的亮度并固定。如果显示环境的环境亮度不固定，则可以根据环境亮度检测装置的检测数据，在显示过程中自动调整灰阶亮度，本公开实施例对此不作具体限定。
可选地，步骤103可以通过以下步骤实现：获取显示装置的蓝光曝辐值，蓝光曝辐值用于表征显示装置的蓝光对人眼的辐射伤害程度；以及根据调整参量和蓝光曝辐值，对显示装置的至少部分灰阶的亮度进行调整，以使蓝光曝辐值小于预设标准值。其中，预设标准值可以为1W/m
2。蓝光曝辐值可以按照以下公式计算：
其中，L
B为蓝光曝辐值，λ为扫描光谱的波长，λ的取值大于或等于300nm，且小于或等于700nm，L
λ为波长为λ的光的辐射亮度，B(λ)为波长为λ的光的预设系数，△λ为光谱扫描的扫描间隔。
可选地，在具体应用中，可以包括三级显示目标：
1、禁止级：根据IEC TR 62471标准要求：显示装置的蓝光曝辐值L
B应符合下述标准：
L
B<1W/m
2
蓝光曝辐值可以表征显示装置的蓝光对人眼的辐射伤害程度，因此，在调整显示亮度时，可以控制显示装置的蓝光曝辐值始终满足上述标准，从而可以避免蓝光对人眼的伤害。
其中，显示装置的蓝光曝辐值可以事先进行辐射亮度光谱扫描后，通过下述公式进行加权得到，并存储在显示装置中。
其中，300nm和700nm为扫描光谱的波段边界值，也就是对大于或等于 300nm，且小于或等于700nm的波段进行光谱扫描。
2、环境级：中间灰阶亮度L
mid＝L
环(L
环为环境亮度)，这样基本保证显示亮度辐射不会超越整体环境。
3、舒适级：最大灰阶亮度L
max＝L
环，这样保证显示亮度不超过显示背景环境的最大反射光强度，显示效果与非发光体接近，人眼长期观看，感觉舒适不易疲劳。
通常，人们对显示亮度可在舒适级与环境级之间选择，对于长期近距离观看，可以选择靠近舒适级。
在环境级和舒适级中，还可以分别根据亮度趋近环境光的程度对其舒适程度进行分级，从而使模糊的防疲劳功能有了一个可以量化的评价体系，有助于推进显示质量的提高。如果单从亮度疲劳考虑，分级如下：
L
max<1.5L
环，为一级舒适；
1.5L
环<L
max<2L
环，为二级舒适；
2L
环<L
max<3L
环，为三级舒适；
3L
环<L
max<4L
环，为四级舒适；以及
L
max>4L
环，为五级舒适。
四到五级舒适适合表现那些图像里有发光体的内容。一到二级舒适适合表现图像里没有发光体内容。三级舒适适合表现混合内容。
如果还考虑蓝光伤害的话，可以根据显示亮度L
s与环境亮度L
环之比，得到通过显示装置的环境因子H，即H＝L
s/L
环，其中，L
s为显示装置显示全白画面时的曝辐值与环境光曝辐值相同的情况下，显示装置的显示亮度，那么可按下述分级形成防蓝光舒适等级标准：
L
max<1.5H*L
环，为一级防蓝光舒适；
1.5H*L
环<L
max<2H*L
环，为二级防蓝光舒适；
2H*L
环<L
max<3H*L
环，为三级防蓝光舒适；
3H*L
环<L
max<4H*L
环，为四级防蓝光舒适；以及
L
max>4H*L
环，为五级防蓝光舒适。
可理解的是，一级是最佳防蓝光舒适护眼等级，二级次之，以此类推。这样量化的分级评价，有助于区别显示装置的防疲劳能力，促进显示装置的改进。
图2示意性地示出了另一种显示参数调整方法的步骤流程图，参照图2，该方法还可以包括以下步骤：
步骤104：根据预设阳光色温，对显示装置的色温进行调整。
具体地，可以通过调整RGB(红绿蓝)三色光的增益来调整显示装置的色温，降低蓝光增益，可以降低色温，并使得整体蓝光辐射强度降低。因此，本步骤具体可以通过下述步骤实现，包括：将显示装置的RGB增益参数调整 为预设阳光色温对应的预设RGB增益参数。
其中，预设阳光色温可以根据阳光的色温6700开尔文(Kelvins,K)进行设定，可选地，预设阳光色温大于或等于6000K，且小于或等于7200K，从而可以使得显示画面的色温趋近于阳光的色温6700K左右，画面色温保持亲自然状态。具体地，预设阳光色温可以为6700K。
进一步可选地，显示装置还可以设有显示页面模式提醒功能。该提醒功能可以提醒操作人员尽可能采用窗口背景暗态化模式及暗态化模式，以减少显示器高亮窗口对操作人员的长期蓝光辐射的无察觉伤害。其中，窗口背景暗态化模式也即是可以设置软件窗口的主题色为低色调、低饱和度的画面，例如浅灰色窗口等。工作页面暗态化模式也即是可以设置word、excel等软件工作页面为低色调、低饱和度的画面，例如豆沙绿的护眼色页面等。
进一步可选地，还可以在根据环境亮度适当降低灰阶亮度的同时，适当在预设阳光色温的基础上提高色温，从而可以满足人们对画面靓丽度的要求，同时又能保证蓝光辐射量没有大量增加。
本公开实施例提供的显示参数调整方法，能够有益于减轻显示装置的蓝光对人眼的伤害。该方法可以以人类长期适应的自然光学环境为无伤害舒适光学环境，以显示装置所在光学环境(背景)对等的自然光学环境为调整标准，以适当的允许浮动范围来调整相应的显示参数以趋近这个标准，达到显示图像对人眼无伤害且感觉舒适的效果。
该方法通过检测环境亮度，以同亮度下的自然光关键参数调整显示参数，以使其蓝光所占曝辐量为显示装置的最佳蓝光分量曝辐量标准，以达到入眼平均有害蓝光分量尽可能低于或接近于同亮度自然光的入眼有害蓝光分量，达成对人眼无害且感觉舒适的显示效果。
在本公开实施例中，首先可以检测环境亮度，然后确定预设条件对应的显示装置的调整参量，其中，预设条件包括显示装置的中间灰阶的亮度与所述环境亮度之间的差值小于或等于预设亮度值，进而可以根据调整参量，对显示装置的至少部分灰阶的亮度进行调整。在本公开实施例中，显示画面的中间灰阶亮度与人眼在相同环境下的适应生理平衡点一致时，对画面的感知就更加舒适自然，因此，可以以显示装置所在的自然光学环境为调整标准，以适当的允许浮动范围来调整相应的显示参数以趋近这个标准，达到显示图像对人眼无伤害且感觉舒适的效果。
可选地，显示装置中设置有亮度检测装置，步骤101可以包括：根据亮度检测装置采集的目标光线，确定环境亮度，目标光线为在显示装置周围的物体表面发生漫反射的光线。
在具体实现中，亮度检测装置的入光口可以正对漫反射面，并且目标光线由漫反射面入射至亮度检测装置的立体角可以大于1sr。其中，漫反射面可 以为经过漫反射处理的背景墙面或标准白板等，本申请对此不作限定。
可选地，步骤101可以包括：首先获取显示装置正对的漫反射面的照度值；然后将照度值与π的比值确定为环境亮度，即环境亮度为照度值除以π的结果。
在具体实现中，由于环境亮度的测量比较复杂，影响因素较多，为了获得比较准确的环境亮度值，可以按照以下几种方式对显示装置进行校准或使用。以下以最大灰阶为255，中间灰阶为127为例进行说明。
第一种，对于背景墙面为较理想的漫反射面的情况，可以首先采用照度仪测量显示装置面对背景墙面的照度值，该照度值值除以π，即为进入显示装置亮度检测装置的标准亮度，可以按照该标准亮度对显示装置的亮度检测装置检测到的亮度值进行校准。后续使用过程中，显示装置的亮度检测装置的入光口可以正对背景墙面，由亮度检测装置采集经背景墙面漫反射的光线，测得环境亮度，并令显示装置的中间灰阶的亮度与该环境亮度一致即可。
第二种，当显示装置的背景墙面、观看者位置以及正对显示装置的位置的照度基本相同时，可以将显示装置的亮度检测装置的入光口对准观看者方向，并将测到的环境亮度作为中间灰阶的亮度。
第三种，可以将显示装置的背景墙面处理成漫反射面，或者将正对亮度检测装置的入光口且不被显示装置遮挡的局部位置处理成漫反射面或近漫反射面，并使该漫散射面到亮度检测装置的立体角尽可能大一些，以保证亮度检测装置所测得的环境亮度比较准确，例如立体角可以大于1sr。在实际应用中，显示装置的亮度检测装置的入光口可以正对背景墙面，同时需要避免室内顶灯或其他墙面的反射光被遮挡而无法进入亮度检测装置的入光口，例如，亮度检测装置的入光口可以设置在显示装置的顶部。
第四种：环境亮度检测装置可以包括一块标准白板，用于将大量的环境光反射至环境亮度检测装置的入光口，由于白板对光线的吸收很少，因此，通过检测标准白板反射的环境光的亮度，可以提高对环境亮度的检测准确度。
采用上述方法中的一种或多种，可以获得比较准确的环境亮度值。
可选地，步骤101可以包括：基于预先存储的环境与亮度之间的对应关系，确定显示装置的使用环境对应的目标亮度；以及将目标亮度确定为环境亮度。
当显示装置的使用环境为学习办公环境时，环境亮度为目标照度与π的比值，其中，目标照度为距离地面120cm的观看高度在水平方向的照度值。
对于比较复杂的环境，可以根据国家标准确定各种环境与亮度之间的对应关系。具体地，可以调整环境光在观看高度水平方向的照度与国家标准一致，将该照度除以π，转换为环境光正对观看者方向的环境亮度，使显示装置的中间灰阶亮度与该环境亮度一致即可。例如，对于学习办公环境，国家 标准为距离地面75cm高度在垂直方向上的照度为300lx。通过实验，距离地面120cm的观看高度在水平方向的照度值即目标照度通常为200lx，可以将200lx除以π的值作为学习办公环境下的环境亮度。因此，对于学习办公环境，可以设置环境亮度或目标亮度为63.7cd/m
2。
可选地，在显示装置安装前，测试观看位置正对即将安装显示装置位置处的照度值，并以此照度值作为基准值；然后安装显示装置，并调整其灰阶亮度，使得在中间灰阶如L
127的显示画面下，在观看位置测到的照度值与基准值一致。

可选地，所述预设标准值为1W/m
2。
可选地，所述第一调整模块，还用于：按照以下公式计算所述蓝光曝辐值：
其中，所述L
B为所述蓝光曝辐值，所述λ为扫描光谱的波长，所述λ的取值大于或等于300nm，且小于或等于700nm，所述L

在本公开实施例中，首先可以通过检测模块检测环境亮度，然后通过确定模块，确定预设条件对应的显示装置的调整参量，其中，预设条件包括显示装置的中间灰阶的亮度与所述环境亮度之间的差值小于或等于预设亮度值，进而可以通过第一调整模块，根据调整参量，对显示装置的至少部分灰阶的亮度进行调整。在本公开实施例中，显示画面的中间灰阶亮度与人眼在相同环境下的适应生理平衡点一致时，对画面的感知就更加舒适自然，因此，可以以显示装置所在的自然光学环境为调整标准，以适当的允许浮动范围来调整相应的显示参数以趋近这个标准，达到显示图像对人眼无伤害且感觉舒适的效果。
本公开还提供了一种显示装置，所述显示装置采用上述的显示参数调整方法进行显示参数调整。
可选地，该显示装置包括背光模组，背光模组的光源的第一光源波段的功率之和与第二波段的功率之和的比值小于50％；第一光源波段大于或等于415nm，且小于或等于455nm，所述第二光源波段大于或等于400nm，且小于或等于500nm。
也即是可以将背光模组中蓝光光源的峰值向长波方向移动，并使其415nm～455nm波段的蓝光功率之和除以400nm～500nm波段的蓝光功率之和小于50％。由于对人眼伤害较大的蓝光主要是短波长蓝光，因此，通过将背光模组中蓝光光源的峰值向长波方向移动，可以降低短波长蓝光对人眼的辐射量，进而降低了短波长蓝光达到视网膜的辐射量，从而降低了短波长蓝光对人眼的伤害，使得显示装置可以符合VDE(德国电气工程师协会低蓝光护眼认证)等护眼认证标准。
其中，将背光模组中蓝光光源的峰值向长波方向移动，可以通过调整背光模组中光源的荧光粉配比来达到，可以减少发蓝光的荧光粉的比例，从而可以减少光源的短波长蓝光的辐射量。
通过对光源改善前和改善后的样机进行功率测试，可以得到如下表1所示的测试结果。
表1
根据上述表1可知，在将蓝光光源的峰值向长波方向移动后，有害的短波长蓝光的比例有所下降，并且有害蓝光所占的比例随峰值波长的增大而降低。上述样品的色温≤9600K，在显示装置目前的色温范围内均可实现。
需要说明的是，上述表1中的数据并不对本公开构成限定。
在本公开实施例中，显示装置采用上述的显示参数调整方法进行显示参数调整，首先可以检测环境亮度，然后确定预设条件对应的显示装置的调整参量，其中，预设条件包括显示装置的中间灰阶的亮度与所述环境亮度之间的差值小于或等于预设亮度值，进而可以根据调整参量，对显示装置的至少部分灰阶的亮度进行调整。在本公开实施例中，显示画面的中间灰阶亮度与人眼在相同环境下的适应生理平衡点一致时，对画面的感知就更加舒适自然，因此，可以以显示装置所在的自然光学环境为调整标准，以适当的允许浮动范围来调整相应的显示参数以趋近这个标准，达到显示图像对人眼无伤害且感觉舒适的效果。并且，显示装置背光模组的光源的第一光源波段的功率之和与第二波段的功率之和的比值小于50％，从而可以降低短波长蓝光的比例，进一步降低了蓝光对人眼的伤害。
