这个屏幕到底是个什么屏呢 [复制链接]

夏普的memory LCD

谁可知道哪里生产的？也是Made in China ?
为什么 不用电子纸呢？两者相比有什么优缺点？

Imagine a display memorizing the image it shows so only pixels have to be rewritten which content changes from frame to frame. Exactly such a display has recently been invented by Sharp based on the company's proprietary Continuous Grain Silicon technology. For this special type of display each pixel is equipped with memory circuitry to save the image information uploaded to the display. Therefore the image information has to be rewritten only in the pixels whereas the content has changed in comparison to the previous picture frame.

With common LC displays microcontroller have to rewrite the complete screen content from frame to frame at a rate of 50 to 60 Hz even though most of the image content remains the same. Consequently standard LCDs have a power consumption which is about 130 times higher than the one of the newly developed Memory LCDs. A Memory LCD of 1.35 inches consumes about 15 μW in operation whereas a standard LCD of comparable size needs about 2 mW to render an image.

In addition, the Memory LCDs provide an outstanding image quality. Different from other reflective displays, the new type of LCD does not need polarisers. Thanks to a special liquid crystal material the image is generated by the status of the pixel just changing from black to white with a reflectivity of 50%.

Due to their miniscule power consumption small size solar cells provide enough electricity to drive Memory LCDs. The new type of display is therefore an ideal solution for small size portable applications such as wrist watches, pulse meter and other fitness devices, price tags, etc. Such systems can even be designed as no-battery applications using solar cells as power supply.
上面是原文的介绍，每一个像素都有一个存储位，不改变显示的情况下，可以不用刷新。
电子纸的显示效果不如这个屏吧！

fucong去哪了，最近没怎么见你到咱们版块逛呢？

逛论坛可是也费时间的吆
再说现在也偶尔去更多的论坛逛逛去了

电子纸的显示效果应该是不如这个，但是有个很重要的，省电呀

功耗上表现还是挺不错的，但比电子纸怕是还是要高些 。
看照片有无光线表现效果都挺好，关键是可用刷新率可以到50Hz，比电子纸高很多，不过刷新率上来，功耗会往上走。

还是欢迎你多回我们版块看看
