Different Specifications of cell phone jammer
Representative models: STN screen is the preferred low-end model, prices are generally no higher than 2,000 yuan, such as the Nokia 6610i, Siemens C62, etc. UFB screen: UFB is Ultra Fine & & Bright abbreviation. In March 2002, as a share of the market share of the world's first LCD Samsung released a phone with the UFB LCD, which is characterized by ultra-thin and high brightness. Designed UFB LCD also features a special grating design can be reduced pixel pitch for better image quality. Here is the inspection items and technical requirements of cell phone jammer.
LCD can display 65,536 colors, to achieve a resolution of 128 × 160 pixels, while UFB LCD STN LCD display contrast or twice, when the 65,536-color TFT display with brightness comparable, but less power than TFT display screen less about price and STN displays, now used UFB display are Samsung and LG in the high-end models, the use of the surface is not very wide. Representative models: Samsung X608 (65K colors), LG 810 (65K colors), etc. TFD screen: TFD is the Thin Film Diode (Thin Film Diode) abbreviation. As the TFT power consumption and costly, it will increase the availability and cost of handsets, so the TFD technology is mobile phone giant screen Seiko Epson developed specifically with the phone's screen. The AC pin and DC plug of the adapter of cellular phone jammer have no looseness.
It is a compromise between TFT and STN, STN better than the brightness and color saturation, but less power than TFT. TFD's focus on features in the "high-quality, ultra-low power, small, dynamic image display capability and fast response time." TFD theory is that it is displayed on the LCD each pixel is equipped with a single diode as a control source, due to the single control design, so that each pixel not affect each other, so the screen can be in the TFD show no blur of motion picture and bright colors. TFD is the same with TFT active matrix drive. Originally developed out of the TFD can only display 4096 colors, but if using image processing techniques can show the equivalent of 26 million color images. However, the relative color TFT display, or in some less, now mainly for Japan and South Korea and other manufacturers to adopt. The nameplate content of the adapter of cell phone jammer should be accurate.
Representative models: Samsung V208 (65K colors), Sony Ericsson Z608 (65K colors), LG8280 (26 million colors), Lenovo G900 (26 million colors) and so on. TFT Screen: TFT (Thin Film Transistor TFT) active matrix type liquid crystal display is (AM-LCD) in one, TFT LCD set back in a special fluorescent tubes can be "active" on the screen each individual pixel control, which is the so-called active matrix TFT (active matrix TFT) of origin, which can greatly improve response time, generally faster response times of TFT, about 80ms, while the STN was 200ms. If you want to raise a flicker will occur. And as TFT active-matrix LCD is liquid crystal arrangement allows a memory, will not disappear immediately after the current restitution. TFT STN flashes also improved (water wave) vague, and effectively improve the ability of playing the dynamic images. Here is the switching-on inspection of the adapter of cell phone jammer.
TFT and STN compared with excellent color saturation, reducing power and higher contrast, but the drawback is more power, and the cost is relatively high. Representative models: the first choice for high-end model, prices are generally more than 2,500 yuan, such as the Nokia 7200 (65K colors), Sony Ericsson K700C (65K colors), Amoi DF9 (26 million colors), NEC N600 (26 万color), etc. OLED screen: OLED (Organic Light Emitting Display) or organic light-emitting displays, mobile phones are emerging on the LCD type, was applauded as a "fantastic display." OLED display technology with the traditional LCD display in different ways, no backlight, with a very thin coating of organic material and the glass substrate, when a current is passed, these organic materials will be light. Here is the electrical performance of the adapter of mobile phone jammer.
