Abstract:
A method for detecting defects caused by mixing colors on a liquid crystal monitor, said method comprising the steps of:displaying a channel drawing on said liquid crystal monitor, wherein a first reference color is allocated on a first corner of said channel drawing, a second reference color is allocated on a second corner of said channel drawing, a third reference color is allocated on a third corner of said channel drawing, a fourth reference color is allocated on a fourth corner of said channel drawing, an intensity of said first reference color decreasing toward a direction to said fourth reference corner, an intensity of said second reference color decreasing toward a direction to said third reference corner, an intensity of said third reference color decreasing toward a direction to said second reference corner, an intensity of said fourth reference color decreasing toward a direction to said first reference corner, wherein each pixel of said channel drawing is shown by mixing said intensity of said first reference color, said intensity of said second reference color, said intensity of said third reference color, and said intensity of said fourth reference color; generating a test message according to said channel drawing; and deciding whether said liquid crystal monitor to be defective by using said test message.
