only the screen content changes when the power consumption power consumption is relatively low

Wear equipment has just emerged, the product form has not yet been established, the manufacturers are still in the end what kind of product can be successful. So in the market, not only different types of products, even with a class of hardware configuration products are also very different Cartier love bracelet replica , the following and watch the home together to see the smart phone screen technology some doorway.
Smart watches touch screen common classification and characteristics
1, Mirasol screen
On behalf of the product: Qualcomm Toq, music source Fashioncomm A1
Features: can display color images, good light experience better.
Samsung Gear released at the same time, Qualcomm also released Toq smart watches. In fact, Qualcomm’s intention is not to be able to wear the equipment market to obtain the number of shares, the main intention is to show, promote Mirasol screen.
Speaking, the characteristics of this screen is really more suitable for smart watches: experience similar to electronic paper, can be seen in the light under the screen, only the screen content changes when the power consumption, power consumption is relatively low. At the same time Mirasol screen display screen is color, and the screen refresh rate is higher, and even display video, these features are not available in electronic paper.
Mirasol screen development is twists and turns, each of its pixels is an IMOD module. Each module consists of a glass substrate and an active reflective film, with a gap in the middle. After the voltage is turned on, the reflective film can move up and down, when the reflective film and the glass substrate is fully aligned, it shows black, and the reflective film and glass substrate distance increases, will show red, green, blue and other colors. As the Mirasol screen structure is more complex, the production is relatively difficult, the product yield is only about five percent, so the cost is also high.
Before Hanwang, Shanda has launched Mirasol screen e-books, 5.7-inch products, the price actually reached 2400 yuan (the price now can buy iPad mini), naturally difficult to be accepted by the market. So in 2012, once came the news of Qualcomm discontinued Mirasol screen.
So now high-pass smart watches in the promotion of Mirasol screen, the high cost of the problem has been resolved? Although we do not know the specific price of the screen, but at least now use Cartier love ring replica Mirasol screen product prices can still be accepted.
Put aside the high-pass Toq, take the recent launch of the fashion source Fashioncomm A1, the price is only 1299 yuan, in the domestic smart watch, really not particularly high. Coupled with the characteristics of power and color display, Mirasol screen may really have a place.
2, Mobius flexible electronic paper
On behalf of the product: Sonostar
Features: Light weight, power saving, can be bent, the screen can not display color images.
Mobius flexible electronic paper is developed by Sony and Yuan Tai, originally this screen is for e-books and other equipment to build, but with the screen size has been done 1.73 inches (resolution 320 × 240), naturally can also be applied To the wearable device, Sonostar smart watch is used in this screen.
Mobius soft electronic paper selling point is in the continuation of electronic paper power-saving features at the same time, the traditional electronic paper in the glass substrate into a plastic substrate, the weight is significantly reduced do not say, but also has a flexible ability.
For example, a 13.3-inch Mobius flexible electronic paper weighs only 93g, while the same size glass substrate electronic paper weight was 144g, the gap is obvious.
But the Mobius flexible electronic paper applied to the smart watch, or will face a lot of problems. Some problems can be solved, for example, electronic paper can not be used in a dark environment, Sonostar smart watch approach is to join the light module, when used or new notice, the screen backlight will automatically light up. As for the electronic paper refresh rate is not high, anyway Sonostar smart watches only show mail, SMS and other information, to avoid the video application, so the impact is not obvious.
And some problems is Mishap, the most obvious is that Mobius flexible electronic paper does not support color display, black and white screen looks and black and white screen mobile phone in general, that experience as if the night before the liberation. Users can not accept this picture, this is a big problem.
Sonostar smart watch screen can bend, mainly based on Mobius flexible electronic paper
3, Mobius flexible electronic paper
Translucent semi-reflective screen
Representative products: Sony SmartWatch2, inWatch Z
Features: a variety of environments can clearly show that the process is complex.
Wearable equipment needs to be used in the outdoors, TFT screen products in the bright light can still maintain a clear Cartier nail bracelet replica display, is a big problem, the common solution is to use semi-transparent semi-reflective screen. This screen technology has been very mature, in mobile phones, GPS and other products have been widely used.
Which is characterized by a layer of reflective film coated in the screen, the light through the reflective film, the light through the reflection of the light back each half. This screen is equipped with a backlight function, can be read in the dark environment as usual, you can clearly show the image in bright light, it can be said to reflect the screen and the advantages of all-transparent screen together.
Translucent semi-reflective screen is the lack of the addition of the reflective film, the production process is more complex, its production focused on Samsung, Sharp and other companies, the price of your side.
At present, only Sony SmartWatch2, inWatch Z and other products using this screen.
4, memory LCD screen
Representative products: Agent
Features: low power consumption, black and white picture.
Traditional LCD screen in use, even if the screen part of the image has not changed, but still have to constantly refresh the screen, which will consume a lot of power.
In response to this problem, Sharp introduced the memory LCD screen technology. The use of liquid crystal panel in each pixel between the larger gap between the pixels in each pixel on the integration of 1bit capacity of the memory, so the screen will not keep refreshing, and to save the purpose of electricity.
But the memory capacity is indeed very limited, the current screen can only achieve black and white display. At the same time, the memory LCD screen also achieved a translucent semi-reflective effect, but is the use of a special liquid crystal material to achieve.
In other words, the memory LCD screen is equivalent to its own backlit electronic paper.
The power consumption of this screen is really low, only 15 microwatts of power are consumed in displaying the image, and the power consumption when updating the image is only 50 microwatts. Because of this, Agent smart watch to achieve 30 days of life (not open Bluetooth), which in the performance of similar products is very top-notch. Memory LCD screen structure is more complex, the cost should not be too low.
At the same time, with the previously introduced Mobius flexible electronic paper, memory LCD screen is black and white display, many users may be difficult to accept it.
The above description of these screens, in fact, many are the first time in the consumer products appear. This shows that the manufacturers of an attitude, that is, what products can be put on the wearable equipment market test, see if the user can be recognized.
The current focus of the manufacturers concerned about the power and adapt to the needs of outdoor applications, which for the extension of life, adaptability is certainly very helpful.
