China LED TV market in a poor light will leave a half to begin to grow up since 2009, will take the LCD TV (LCDTV) from May of 2009 to May of 2010 Sell 18.65 percentage points of growth by a wide margin of proportion, especially after the vacation on May Day of 2010 finish, relatively rise to 10 percentage points, and cold cathode tube (CCFL) without a break in March even more LCDTV price in a poor light is compared, about 3 times will be dropped to 1.5 times of May of 2010 while putting out 2008 too, will drop to even more 1.2 -fold most lower by August of 2010.
The looks relatively soars in LED TV sales volume in a poor light continuously, the sales volume of CCFL TV in a poor light begins to glide, beautiful, Su Ning reacts in one, retail sales of Line two city to buy to sell the shop country from the full-length electric apparatus quantity, in LCDTV sales amount during May Day, LED TV proportion in a poor light is promoted to nearly 40%, relative CCFL TV in a poor light d...

O Foreword
The digital picture frame is the electronic consumables of the fashion, it is indispensable adornments of family too, it is one kind, in order to store, return and have a look around the digital photo as the electronic product of the core function. At present, the digital picture frames mostly regard single chip as the solution on the market, represented by ESS/ AML0GIC/ MPX chip design, in terms of its procedure of design, there is no but hardware design in a strict meaning that is only the software design. The key device of the hardware system is available, the function is definite, the structure is stationary, the command system can’t be changed, thus cause the hardware to organize the scheme and connect the scheme and limit. So, the staging or expansion that please be great, it is not all right to lean against the simple firmware staging, must adopt the better key device, design the brand-new hardware system.
This literary grace has realized... Read more

In recent years, development of programmable logic device, make SOPC (System On A Programmable Chip, programmable block pay system) Become possible, namely realize the overall system on the programmable chip together. Nios whether the intersection of Altera and whom Company research and develop can be used in the processor soft core that SOPC designed. Because of the intersection of Nios and soft nuclear the intersection of SOPC and system, maximum its characteristic flexibility, can according to the needs of one’s own one flexible to change peripheral device of Nios, make the intersection of hardware and utilization efficiency reach highest, he have ISP (In System Programmable at the same time, in the intersection of system and programming) Function,be can cut down and can expanded, but upgrade. This text utilize the intersection of Nios and the intersection of system and flexible advantage that make fully, design, realize a CT machine scan the system contr... Read more

Need to release the changeable real-time information or place advertised in some such as the station, store, school, blackboard, paper or the traditional media means of the neon bulb bill-board, no matter has already unable to meet the present demand on display effect or modifiability. And LED be consumption saving, low cost, longe-livedded dot matrix display screen, space usage is little and can characteristics such as real-time display,etc., and reveal the information volume of the content is big, users can edit and revise and reveal the content arbitrarily by oneself at any time, so, already used widely in recent years.
2 overall designs
The system has adopted & mdash of upper computer; — The structure of the lower-position unit is constructed, the upper computer is a PC, carry on communication [1 ] through the serial communication interface and display system of the lower-position unit, in order to realize it to revealing erasing, upgrading etc. operat...
