Liquid crystal display pixel is also called little absence, it refers to the LCD screen display black and white and red, yellow, blue three primary colors of the pixel points, each point is defined on a subset of pixels. So far, the liquid crystal technology development up to now, still not fundamentally overcome the defects. Dead pixels can be roughly divided into two categories, which are both dark pixel screen display content how to change to display the contents of the" black".

Dead point detection and screen the correct use method

Liquid crystal display manufacturers generally explained as long as the pixel quantity and distribution does not exceed a certain standard, the occurrence of one or more pixel of the liquid crystal display is normal, is consistent with the industry standard. Here special attention is required to distinguish between a" window" and" dead", there is no bright spot, does not mean that no dead pixels! Many manufacturers have some obvious bright and dark spots panel recycling into less obvious point grey. With the aggravation of competition and technology to improve the technological level, the LCD screen of the manufacturers to improve the material standard, strengthen the production and inspection of internal quality control, greatly reduced the frequency of their occurrence.

Check point of the method is simple, as long as the LCD screen brightness and contrast to the maximum or transferred into a minimum, you may find, screen has many bright or dark presence.
