Physical size is the actual size of the screen. Large screen at the same time must be equipped with high resolution, that is, under this size can be displayed in the number of pixels to display more pixels, can be expressed in the greater room for nature. About the size of two large mobile phone screen, but one can only display two lines of Chinese characters, the other five elements of Chinese characters can be displayed, the font size differences aside, the key is the screen resolution, which resolution is larger, naturally in the same font size of the next line can display more characters. Indeed, a good color screen phone, the screen resolution is not large enough to show, no matter how high the quality of what is the use of color. Color cell phone screens is generally about 128 × 128. If you don’t want to be interrupted during the meeting,   Cellular Phone Jammer  will be a good choice.
LCD screen resolution is the number of cells (in the point [dot]) is obtained by dividing the screen area of the screen resolution, picture quality of this indicator is to determine the biggest factor. Therefore, in the purchase of color-screen cell phone only to focus on the screen can display color depth, screen resolution is also a very important decision indicators. 128 * 128 dot matrix screen (or (128 +-x) * (128 +-x), x between 1 and 32), width and height ratio of 1:1 (or 4:3,3:4 ), is the most common cell phone screen, the most appropriate display resolution standards, the equivalent of a computer screen display of 800 * 600 resolution. You will need this kind of   cell phone jammer  during the meeting.
Refers to the so-called black and white color or gray-scale display shows the difference of light and dark pixels in the color display in the performance of different color, gray scale, the more clearly the more realistic the image level. Corresponding to each pixel gray level depends on the memory cell to refresh itself and display the median performance. If the color of each pixel with 16-bit binary number that we call it 16-bit map, it can express 2 ^ 16 65536 colors. If each pixel with 24-bit binary number that we call it 24 maps, it can express the power of 2 24 16777216 colors. mobile phone jammer can continuously work for 12 hours.
Lithium-ion battery materials, a high energy density batteries. Intelligent Lithium-ion battery or a battery, it can be used with smart charger with special original, to the shortest charging time, the largest life-cycle and the maximum capacity. Lithium-ion battery is the best performance of the battery. With the same size nickel-cadmium batteries, nickel metal hydride battery, the maximum power reserve, lightest, longest life, the shortest charge time, no memory effect. In the phone, both from a technical point of view or from the assessment of price considerations, the battery plays a very important position. Until now, the market is sales of mobile phones, used batteries have basically completed the battery from nickel to lithium transition. Perhaps because of cell phone battery has just completed a revolution in nickel batteries to lithium batteries, lithium batteries so people know not unified, in many cases is not correct to say and practice is quite popular. Therefore, to understand that lithium knowledge, learn the proper use of lithium batteries is necessary. After 12 hours, cell phone jammer  needs to be closed for 20 minutes.
Currently on the market used mainly nickel-metal hydride rechargeable batteries (Ni-MH) and lithium-ion (Li-ion) types. Lithium-ion batteries in mass production of liquid lithium-ion battery (LiB) and lithium-ion polymer battery (LiP) two. So in many cases, marked on the battery of Li-ion, lithium-ion battery must be. But not necessarily liquid lithium-ion battery, is also possible that lithium-ion polymer battery. And then, cell phone jammer can be switched on again.
