(Summary description)light and thin The thickness of E-ink display devices is usually very small, the weight is also quite light, but the structure is more durable than ordinary LCD. Can these advantages make it not favored by those portable device manufacturers? Traditional LCD devices are limited in terms of structure. Its thickness cannot be too thin (if the thickness of the two layers of glass of the LCD screen is 0.7mm, and the thickness of the two layers of substrates is 0.5mm thick, then the thickness of the LCD screen will not be less than 2mm), The weight can't be too light either. The hardware structure of the electronic ink display device is quite simple, its thickness can be about 1mm, and the thickness of the display screen is less than half of that of the LCD. In addition, e-ink has a wide range of applications. It can be used not only on glass surfaces, but also on surfaces such as plastics, so it will not be as fragile as LCD displays. A comparison of thicknesses of TFT LCD displays, first-generation e-ink displays, and future e-ink displays is shown. Low power consumption The power consumption of e-ink is quite low, and it can display a picture even when the power supply is briefly stopped. The reason for its very low power consumption is that its reflectivity and contrast are very high, and there is no need for backlighting to improve readability. To sum up, the display device using e-ink technology will have the same visual characteristics as paper media, but also have the advantages of low power consumption, thin thickness and light weight, making it a new favorite of portable devices, especially for those who require These are applications where transmissive LCDs and reflective LCDs cannot meet the requirements of better display effects under all kinds of light. Simple process The electronic ink display device can follow the production equipment of AMLCD, and the production process is simpler. Just apply the electronic ink to the IT0 plastic substrate, and then use the Laminator process to attach it to the TFT backplane. This process is the same as the polarizing film attachment method in the LCD production process, and this process can be used Existing equipment or similar equipment for production. The simplification of the production process means higher yields and higher yields, coupled with a reduction in substrate thickness, which results in significant cost reductions (still more expensive than paper, of course).
