Why Does Reducing Color Space in Portable Displays Benefit Eye Sensitivity?

Color spaces in displays for portable electronics, such as laptop computers, are smaller than those for televisions due to battery power limitations and the desire for maximum brightness. This reduction in color space is beneficial because it aligns with the human eye's sensitivity function and the CIE diagram, resulting in more efficient use of power and a better display experience.

The color coordinates of displays for portable electronics such as laptop computers generally provide smaller color spaces than for television. Battery power is a critical limitation on the light sources used for the display and maximum display brightness is desired. Explain why a reduction in color space is helpful with reference to the eye sensitivity function and the CIE diagram. See if you can obtain the color spaces used in portable electronics.


So what I think to approach the problem:

looking at the CIE diagram it shows us the corresponding colors region to there wavelengths. If we take a wavelength and look it up on the eye sensitivity diagram we can see the luminous efficiency which has the unit of (lumins/Watt) on the right hand side and eye sensitivity function (v(lamda)) on the left hand side . We also know that the human eye peaks at 555 nm (green light). increasing the voltage would increase brightness, I am not sure what my prof means about reducing color spaces is helpful

thanks

Reducing the color space means reducing the range of wavelengths, yes? And the eye's sensitivity tails off at edges of the space, right?
 

Related to Why Does Reducing Color Space in Portable Displays Benefit Eye Sensitivity?

1. How do our eyes detect colors?

Our eyes detect colors through specialized cells called cones, which are located in the retina. These cones are sensitive to different wavelengths of light and send signals to the brain, allowing us to see a range of colors.

2. Why do we see certain colors as "bright" and others as "dull"?

This is due to the sensitivity of our cones to different wavelengths of light. Our eyes are most sensitive to green light, which is why green objects tend to appear brighter to us. Colors that are further away from green on the color spectrum may appear duller because our eyes are less sensitive to those wavelengths.

3. Can our eyes see all colors?

No, our eyes are only capable of seeing a certain range of colors. This is due to the limited number of cones in our retina. The average human eye can see about 1 million different colors, while some animals such as birds and insects can see a much wider range of colors.

4. How do colors affect our mood and emotions?

Colors can have a significant impact on our mood and emotions. For example, warm colors like red, orange, and yellow are often associated with energy and happiness, while cool colors like blue and green can have a calming effect. The specific emotions evoked by colors can also vary depending on cultural and personal associations.

5. Can eye sensitivity to colors change over time?

Yes, eye sensitivity to colors can change due to various factors such as age, health conditions, and exposure to certain substances. For example, as we age, our eyes may become less sensitive to certain colors and we may have a harder time distinguishing between similar shades. Certain health conditions, such as color blindness, can also affect our eye sensitivity to colors.
