National Semiconductor Asia Pacific marketing manager for power management products, said Wu Zhimin, TFT backlight application and other similar applications in the digital photo frame, LED backlight the main challenge is how to control the constant current flowing through the LED and produces a higher contrast. He stressed that “in addition to AC adapter, some digital photo frames can also be powered by a lithium-ion battery. To extend battery life, power and efficiency become very important factor.”

Wu Zhimin Description, National Semiconductor has a variety of LCD backlight solution, widely used in digital photo frame applications for small panels and large-size panels (20 inches).8 Inch Touch Screen LCD The latest LM3431 is a step-up controller integrated 3-channel constant-current regulator. It can be provided for the three series of high-precision LED constant current. The maximum output current of 150mA, through the expansion drive after 6 LED string. LM3431 provides excellent performance PWM dimming, dimming frequencies up 25kHz, this time to support 100:1 contrast ratio. 8 Inch Touch screen VGA Monitor If the dimming frequency to further reduce it, the contrast will be more than 1,000:1.

NXP Tim Chen that the digital photo frame applications codec processing will be another challenge. “Many users like the product of media-based VLIW DSP processor, however, to conduct real-time H.26? 1080i HD decoding and encoding is very challenging. Perhaps to the existing DSP technology, to use 2 to four chips to achieve this goal. “NXP’s program in, TM3282 is a VLIW media processor TriMedia 32 the latest version, it has sufficient computational performance to handle a variety of operating modes the future. The processors are able to multi-frame rate compressed video stream and associated audio stream to decode and encode. In addition to VLIW core, PNX1005 also includes a bit co-processor and embedded trace module.8 Inch Touch screen Monitor In addition, removed in the PNX1005 chip 2D graphics capabilities, and to 0.09um process design, so to further reduce costs and power consumption.

Shen Zhen Jia Wen product group is of the view, digital photo frame chip will be the trend toward SoC development to significantly reduce the cost and type of chip DSP SoC not need to consider a higher power consumption and overheating.

LCD screen is a precious component, if not dirty, then you can use the soft wool and gently brush Shan Shan 1, it is recommended to use ordinary make-up brush, this brush hair texture is very soft and will not scratch the screen, so it is easier to buy, if no can also try to use washing balls blew the ears. If it is dirty, you can use a clean cotton cloth of fine to be careful when cleaning the bathroom clean, attention must not use any chemical cleaning LCD screen! Sometimes, you may encounter some very stubborn stains, this time would be for a professional of – SONY LCD screen Chupin special cleaning agent KK-LC3! 7 Inch Touch Screen LCD This LCD stain killer course, the prices cheap, a vial is necessary to RMB 150 or so, the effect of natural doubt. Actually, we can consider the use of soft and smooth cotton or chamois glasses cloth dipped in clean water to wipe a small amount, the effect has no professional person so perfect, but the win in the cheap. Friendly reminder: wipe must be shut down state, and the amount of detergent or water must not be too much.

leaving Zhang useful tissue
Do not know if you noticed there is no, the new machines purchased before Kaifeng between the keyboard and LCD screen, there will be a separate tissue. Otherwise, when combined on a notebook computer, the keyboard and LCD screen may produce friction, resulting in Huaping situation. Some ideas ahead of books to address this problem have their own methods, such as SHARP’s UM series machines using a novel keyboard lift technology, when combined on a notebook computer, the keyboard will automatically drop 3MM.7 Inch Touch screen VGA Monitor And some books provides an LCD protection cover. But for other notebook computer users, to retain the affiliation of new tissue machine shop on the keyboard is the most effective approach.

demolition is not our work
“To avoid electric shock, do not open the rear cover on their own. For service, please contact with professional or authorized.” This phrase is very familiar, right? It is these, including many electronic products including laptop insert of the classic statement. In fact, the same as with other electronic products, LCD-house will produce a high voltage, privately apart to be very dangerous.7 Inch Touch screen Monitor Therefore, never attempt to demolish LCD, this is not explored and it-yourself questions. If you have favorite books of the LCD screen have any questions, or to the professionals to be demolished bar!
Unconsciously so much maintenance that note, I believe you on how to maintain and safeguard their beloved notebook LCD display already have a clearer concept. I hope you precious books of the “face” can be open-minded care of you every day to give you a good mood.

Stylish compact, do not rinse photos will automatically play digital photos, recently, a shape similar to the frame, mainly

used to display electronic images of digital products are selling the sea.
May sell hundreds a day
This morning, reporters visited the DC City, Gome, Suning Appliance and other large markets, sales of digital photo frame

counter, while small, but each has a number of front counter to come to consult consumers.

It is understood that the digital photo frame market, according to style, and configuration features of the different

prices from 200 yuan to 2,000 yuan ranging from relatively low prices of digital photo frame is relatively early stage of the

product, 7-inch LCD screen,7 Inch Digital Photo Frame support SD / CF / MMC / MS memory cards and other mainstream, which only supports JPEG images

with a resolution of 380 * 270-600 * 800, and now the second generation of products have more features, not just playing

images, but also can play MP3, MP4 a variety of formats such as music, video, display the greatest has reached 10.4 inches.
“Now this latest has 2G of memory, and built-in lithium battery.” A salesman surnamed Li told reporters that the new

models this year, is not only more features, such as calendar, alarm clock, background music, etc., the appearance of more

and more ingenious design refinement.7 Inch TFT Screen Digital Photo Frame Including one with 600 crystal irradiation by 14 spotlights in the pictures, and more

bring out the effect of the photo, of course, prices are not cheap. DC City, a counter salesperson told reporters that more

than two months, and the sales of this product has been good, “according to the different customer needs, each price has a

popular person. A good day to be able to sell hundreds of times ! ”

Cottage machine more powerful
According to insiders, to enter the market, apart from Haikou certain products, there are a number of international

brands of cottage version. Shop Jiefang a reporter to see a grid of a faction known as the digital photo frame cottage for

sale, this machine has 7-inch display, appearance and very much like a well-known brands. According to the boss introduction,

this machine is very powerful, 7 Inch photo frame not only can see pictures, you can also play music videos, as long as the price of 260 yuan,

while the same function of the price the big brand-name computers have at least 800 yuan.

Although digital cameras have become popular products, digital photos has almost replaced the traditional paper-based

photo printing digital photos, but very few people, statistics show that less than 35%.
To industry sources, the digital photo frame prices were relatively very low, as a fashionable home digital products, has

become the mainstream of small digital market, the future will have greater potential for development.
