A contrast effect is the enhancement or diminishment, relative to normal, of perception, cognition and related performance as a result of immediately previous or simultaneous exposure to a stimulus of lesser or greater value in the same dimension.
Have you ever entered a movie theater on a sunny afternoon? The room probably appeared completely dark but as your visual system adjusted to the reduced level of light you were able to see better after a few moments. This "adaptation mechanism" allows our eyes to recover from an oversensitivity to a particular stimuli. "Chromatic adaptation" occurs when our eyes adjust to certain color stimuli. Follow the instructions below and see how the visual system responds to a color overload.
Instructions: Fixate upon the black spot in between the uniform cyan and yellow areas for about 30 seconds. Then scroll down and shift your gaze to the black spot in the 2nd image. Note that the image of the seaplane appears approximately uniform after this adaptation.
This is an example of "successive contrast". This occurs when the perception of currently viewed test field is modulated by previously viewed test field.
One more example - Stare at the two colored circles on the top row for a few seconds and then shift your attention to the two circles in the bottom row.
"Simultaneous contrast" refers to the manner in which the colors of two different objects affect each other.
Colors often appear brighter and more vibrant when they are bordered by frames. Black lines are commonly used to enhance colors in applications like stained glass. This tactic creates a certain effect, as shown below, and prevents color clashing. Notice that the drawing on the left colors appear significantly brighter and pure.
When a tree fall is the forest and no one is around does it still make a sound? Well yes it does as the physical property of the breaking creates the acoustics and noise as sound. However if the is a beautiful red sunset and no one is around to view it Â– is it still red? Well the answer is yes and no! The electromagnetic properties of the light will be present but color is a perception and uses the viewer to produce the color.
In the image here, the two inner squares are exactly the same shade, but they appear to have different shades due to the background provided by the outer squares.
Both gray areas are of the same shade and intensity. Place a vertical pencil at the center of the picture on the left. Do the sides of the gray circle appear the same?

• We will use raised fund to install 5G (more than 1m2 glass) sputter equipment and operations of company for 1 year or more.
• In this period, we will focus on develop products with several customer (some of them already connected) and some small products like auto-dimming mirror will be sold to automotive company.
• Company also prepare for the next round investment which is to enter the smart window business (for vehicle and for building)
2 persons who have more than 10 years experience on display, solar-cell business in LG and Samsung, founded together to achieve full solid state, inorganic electrochromic device manufacturing technology on 29. Feb. 2016. We prepared 3 years before foundation to see the feasibility of business and to check the possibility of technology. Several experiments are made in this time to get the confidence of technology.
We established the newly developed electro-chromic technology with the help of vacuum deposition technology used on semi-conductor or display business. And our products composited with full solid state, inorganic material to accomplish long life time and small energy consumption.
We already have several registered patents and know-hows for our unique structures, materials and manufacturing technology. Now we have small size of research FAB in Korea and 9 employees.
This clip shows how fast change it's color when the full solid state and inorganic electro-chromic manufacturing technology is applied.
With the vacuum deposition technology, we can manufacture smart window not only for the flat glass but for the curved glass and flexible film also possible.
Now we can achieve transmittance control less than 2% when it is dark and more than 60% when it is bleached but this range will be extended in near future
