现在的显示器多为OSD控制模式的,当我们调整显示器时会发现有一项指标是“色温”值的设定,那么色温的含义究竟是什么呢?调整色温值的大小对用户有什么用处和好处呢? 色温实际上是一个物理学方面的概念,色温是以标准黑体辐射频率为基准源,来定量描述色彩的一种方法。标准黑体在加热后,辐射频率与温度之间会呈现的一种特定的函数关系。随着温度的升高,黑体所发出的光色逐渐从深红慢慢的转换成蓝白;同样道理,随着温度的降低,黑体所发出的光色逐渐从蓝白慢慢的转换成深红。当某种发光体发出的光的光色与黑体光色相同时,我们就说二者的色温值是相同的,色温的表示单位是绝对温度K。也就是说,如果某两种发光体所发出的光具有相同的色温值(即K值),给人眼的感觉就是它们的颜色和亮度是相同的。自然光的色温值是6500K,如果某种光源的色温值也是
Now the monitor is mostly OSD control mode, when we adjust the monitor will find that there is an indicator of the “color temperature” value of the setting, then what is the meaning of color temperature? Adjust the color temperature value of the user what is the use and benefits Color temperature is actually a physics concept, color temperature is based on the standard blackbody radiation frequency as a reference source, to quantitatively describe a method of color. After a standard blackbody is heated, the radiation frequency and temperature will assume a specific functional relationship. As the temperature rises, the color of the light emitted by the black body gradually changes from deep red to blue and white gradually. Similarly, as the temperature decreases, the light color emitted by the black body gradually changes from blue to white slowly red. When the light color of a light emitting body is the same as that of the black body light, we say that the color temperature values of the two are the same, and the unit of the color temperature is the absolute temperature K. That is to say, if the light emitted by two light emitters has the same color temperature value (ie K value), the feeling to the human eye is that their color and brightness are the same. Natural light color temperature value is 6500K, if a light source color temperature value is
