Display highlights, dark dots and bad points detection methods

We are in the purchase of monitors, often worry about the display screen bright spots, dark spots and bad points, today's small series on how to detect the display highlights, dark and bad points of the method.

In general, we will use detection software to view, here Small series for everyone recommended driving life, simple operation, easy to use.

Display highlights, dark dots and bad points introduction instructions

The bright spot is refers to in the black screen case presents the R, G, B's point is called the bright spot. The appearance of the bright spot divides into two kinds of situations: in the case of black screen, the point of the color of R or G or B is simply presented; When switching to red, green, and blue three-color display mode, only in R or G or B in one display mode with white dots, and in the other two modes have other color points, In this case, there are two bright spots in the same pixel.

The visual range of the detection highlights is around 35cm and the line of sight is perpendicular to the screen (judged within 10 seconds). Some of the highlights are to be seen in different colours. The general "bright spot", the size is just full of a pixel, the screen for the black, you can see, do not use a magnifying glass, and the size and ballpoint pen on the paper point of the size of the similar. However, there are a class of points like the bright spot after the boot (or after the use of a period of time) on the constant light, but brightness than "bright spot" to low, size does not account for a pixel, without magnifying glass is more difficult to find, eyes almost affixed to the panel may find that this kind of point is called "micro-FAI Point", "micro-hui point" is not a bright spot (of course, not bad).

The dark point is that in the case of screen, the presence of a non pure R, G, B is called a dark point. The appearance of dark dots is divided into two situations: in the red, green, and blue three-color display mode, in the same position only in R or G or B in a display mode with black dots, this situation indicates that there is only one dark spot in this pixel; in red, green, and blue three-color display mode, There are black spots in both the R or G or b display modes in the same position, which indicates that there are two dark dots in the pixel.

The bad point is that the LCD screen consists of two pieces of glass, about 1 mm thick, the middle is about 5 microns (1/1000 mm) of crystal droplets, separated by evenly spaced, contained in a small cell structure, each three cells constitute a pixel on the screen. The lattice is rendered under a magnifying glass, and a pixel is a point of light. Each point of light has a separate transistor to control the strength of its current, if the point of the transistor is broken, it will cause the light point will always light or not light, which is mentioned above the bright spots or dark points, collectively referred to as "bad point."
