Since each vendor's market share is small, with between products and there are some differences, so that its decision makers have little effect on other firms, competitors do not cause attention and response. Thus the characteristics of firms often act alone. In several major shopping centers we visited, we found that not all actions are the same companies, such as we see Nokia's welcome in the so-called summer offer, some models in a sale, but Apple's new phones are struggling for market publicity. Because firm size is generally not large, the required capital into or out of not too much, converting other products or provide other services on more easily. Many mobile phone manufacturers in the loss of time, generally will not continue to stay in the industry. Monopolistic competition in the market, the brand of goods is extremely important, because as a consumer product quality, functionality is preferred, we as a consumer under normal circumstances will not buy what we had never heard of products and services. In order to highlight the characteristics of their products, manufacturers will spend a lot of effort in advertising, trademarks, packaging, thereby causing the consumer's attention and stimulate their desire to buy. Samsung, Nokia, Apple, and so the brand, its advertising too numerous to mention. The main computer can show the situation of cell phone jammer system.Now, however, the use of DSTN-LCD computer CPU and RAM for high speed and stable performance, this phenomenon has rarely seen out of sync. Pixels on the screen because the information is from the screen left and right sides of the transistor control to display an entire row of pixels, each pixel can not be self-luminous, is a passive image point, so the slow reaction speed, screen brightness darker than the CRT monitors were and more. As DSTN-LCD's contrast and brightness poor, small-screen viewing range, the color is not rich, especially the reaction was slow, not suitable for high-speed full-motion images, video and other applications, it is generally used for text, tables, and still image processing . However, because of its relatively inexpensive, less energy consumption than the TFT-LCD, and view the contents of the small screen to prevent secret spy role, a simple structure can reduce the machine size and other characteristics, there are still applications in low-cost notebook. TFT (Thin Film Transistor) that thin-film field-effect transistors, active matrix liquid crystal display is one.
