If you heard term passive matrix laptop screen being thrown around, and weren't sure what it meant, then you want to read this article.
Specifically we will discuss the difference between a passive matrix and an active matrix laptop screen, give a brief history about a passive matrix laptop screen, and provides some different definitions as well. After reading this article, you should have everything you need to know about passive matrix laptop screens.
All passive matrix displays are LCD displays, which stands for liquid crystal display. All LCD displays are thin, flat display devices which use dots, commonly referred to as pixels, to show images on a screen. Since these monitors use small doses of electrical power, they often have battery-powered electronic devices connected to them.
Passive matrix laptop screens come in a variety of qualities, depending upon several important factors. The most important is resolution, which is represented by how many pixels are displayed horizontally and vertically on the screen. For example, a resolution display most commonly used for laptop computers is 1024 x 768. Also, the size of the screen is important. The diameter of the screen is found by measuring diagonally from one corner to the other. Generally, the bigger the screen, the better the resolution. Finally, response time also plays a factor. Response time is the time it takes to change the color or brightness of the pixel. Passive display LCD monitors are rarely used by laptops today. This is because they have been replaced by active display technology. The difference between active display versus passive display resolution has to do with the refreshing of pixels. In an active display, the pixels are charged by a current, display for certain amount time, and are refreshed continuously by new pixels. Because of this displaying an refreshing, in active display monitor has a sharper and brighter image than a passive matrix display. In fact, it is very rare to see a passive matrix display laptop screen being used when manufacturing a new laptop. Manufacturers have mostly gone to active matrix display screens, for the reasons cited above. In conclusion, I have given you the history, some factual references, and a brief overview of the difference between an active versus passive matrix display screen. Now you should be better versed in different kinds of laptop screens, and have better knowledge of display properties, when it comes to lap top screens.
