used in mobile power bank fidelity occasions

by Mobile Mobilepower mobilepower The difference between digital photo frame digital screen mobile power for iphone and analog screen Difference between the LCD display digital screen and simulation screen technology principle here is not about their performance should mobile power be considered as a digital photo frame user, except as follows: a digital screen in the whole process of image processing using digital signal no distortion, used in mobile power bank fidelity occasions; simulation screen in the part of the drive circuit, the analog signal is used, there will be losses in the signal transmission and conversion processes, there are signal to noise ratio, and thus are generally only used in mobile power bank the display effect and stability degree insensitive occasions. 2 digital screen mobile power for iphone is a progressive scan high-definition signal, and the analog screen is an ordinary video signal of the interlaced scanning. For example, the 7 analog screen digital photo frame, corresponding to the television signal of the NTSC system, each frame consists of 525 scanning lines, to remove the inverse process of scanning, mobile power for iphone wherein the effective display 480 lines, is interlaced, each field contains only 240 scan lines. system design reasons, as the simulation screen also only use 234 philips digital photo frame 7 digital screen, each frame is a 480 lines per field, able to perfectly reproduce mobile power bank the fine detail of the image . Digital screen for both display dynamic picture perfect mobile power display static images. Early mobile power analog screen used to display static images (digital photos), there will be a feeling of jitter and shimmer, in fact, is only suitable for display TV a dynamic image. However, as technology advances, now part of the simulation screen display still pictures can reach a level close to the digital screen, consumers in the actual purchase products should note the difference in screen quality. Price, of course, mimic panel cheaper. But in terms of quality, the digital screen. '
