steady. Some of style of this solution such as 8380 and 8381 can't
support Divx. For this solution it can support display pictures, play
music and video.

install to work. The price is also around USD13, can't support built-in

Now the panel in this market is AU INNOLUX brand for 7" frames, most
factories use it with CCFL which the steady and brightness and color is
not that good, with CCFL panel, there are some shake and wave in the
screen, but if use LED-background instead then the effect is good.
About the panel used in big size frames like 10.4", 12", 15" ... and so
on, many factories offer a very low price, in fact the panel they use is
B grade panel and the quality is not that good. About the cost of 10.4"
panel, the original newest panel of grade A is around USD80 and the unit
price is around USD120, but some customers like cheap price so
manufacture can also use B grade panel and the price is about USD95.
