不同防蓝光眼镜对屏幕显示效果的影响比较
|
摘要
为了定量分析不同防蓝光眼镜的使用对屏幕显示画面彩色三要素的影响,分别采集6 500K和5 000K色温下的OLED屏幕与LED背光的LCD的光谱分布,以及当前销量较大的5种不同材质防蓝光眼镜透射率数据,通过OriginPro拟合、色度软件分析、Matlab计算,定量比较5种防蓝光眼镜对不同色温下两种屏幕1931CIE XYZ色坐标、主波长、饱和度及光通量的影响,结合人眼分辨率对计算结果进行分析。结果表明,5种眼镜对屏幕色坐标Z值降低效果相差最大值高达1 881倍,相同色温同一眼镜对LED背光的LCD屏的防蓝光效果略强于OLED屏;5种防蓝光眼镜对色温为5 000K的LED背光的LCD屏幕主波长影响不大;能过滤掉色温6 500K的OLED屏幕99.626%蓝光的眼镜,可使其饱和度增加22.7倍。能过滤掉色温6 500K的LED背光LCD屏幕99.59%蓝光的眼镜,可使其色温下降为原来的0.322倍,均严重影响屏幕的显示效果。该研究方法与结论可为相关产品的使用和研发提供借鉴。
In order to quantitatively analyze the impact of different anti-blue light glasses on the three factors of color on screen display,the spectral distribution of OLED screen and LCD with LED backlight at 6 500 Kand 5 000 Kcolor temperature were collected separately,and the transmissivity data of current five anti-blue light glasses made by different materials in large sales volume were adopted.Through OriginPro fitting,chrominance software analysis and Matlab calculation,aquantitative comparison was conducted between the impacts of these five anti-blue light glasses on 1931 CIE XYZ color coordinate,dominant wavelength,saturation and luminous flux of two screens at different color tem-peratures.Also the calculated results were analyzed in combination with visual resolution.The maximum difference among the five types of glasses in reducing the Z value of color coordinate is up to1 881 times,and the same glasses under the same color temperature exhibites slightly stronger bluelight prevention impact on LCD with LED backlight than on OLED screen.In addition,these five types of glasses pose insignificant impact on the main wavelength of LED backlight LCD screen under color temperature of 5 000 K.Moreover,the glasses which are able to filter out 99.626% blue light of OLED screen with color temperature of 6 500 K,lead to an increase in the saturation by 22.7 times.The glasses filtering out 99.59%blue light of LED backlight LCD with a color temperature of 6 500 K can reduce the color temperature by 0.322 times,which seriously damages the display effect of the screen.This research provides a reference for the use and development of related products.
