With the development of time,the technical advantages of electronic paper have been recognized continuously,and more and more applications have been involved.But It may be difficult for some new users to understand at once.We list some questions that everyone is most concerned about to help you understand e-paper quickly.
Q1:What is e-paper?
Electronic paper is the electronic ink coating on a layer of plastic film,can be pasted on the thin film transistor(TFT/PET/FPC material)circuit,through the drive IC control,forming pixel graphics.
Q2:What is the display principle of electronic paper?
E-paper displays are based on e-ink technology,which uses tiny”microcapsules”on the surface of the screen to encapsulate negatively charged black particles and positively charged white particles.By changing the electric charge,the different colored particles are arranged in order to create a black-and-white visual effect.
Q3:Will the response time of the e-paper display be slow?
The response speed of electronic paper is about 50-100 milliseconds,which is suitable enough for everyday still pictures with slow switching frequency.Compared with traditional display screens,electronic paper has many advantages such as paper-like feeling,clearly visible in the sunlight,ultra-low power consumption and so on.
Q4:Why can the electronic paper display be super long standby?
In the absence of power supply,the screen image will not disappear and still display continuously.The electronic paper display screen uses bistable technology,power is consumed only when changing pictures,and does not consume power when the picture is still.Compared with other display products,the electronic paper display screen has excellent power saving performance.
Q5:Can the electronic paper display be read properly under sunlight?
The electronic paper display does not need backlight at all.The ambient light source is used to hit the electronic paper display screen and then refract the light to the eyes of us,which is the same as the visual principle of traditional paper or objects in life.Therefore,the brighter the ambient light source,the more clearly the electronic paper will be visible,And it has a wide viewing Angle of 170°.
Q6:Why do electronic paper screens protect your eyes?
Electronic paper displays can reflect ambient light,while other technology displays use strong backlights adjusted by liquid crystals.These light sources directly into the eyes can easily lead to dry eyes and visual fatigue,and blue light can cause eye lesions and other problems.Electronic paper display without backlight module can ensure eye health.
Q7:Can the electronic paper display is not damaged after bending?
The electronic paper display,which is as light as paper and can be rolled and folded at will,it is also very portable because it is made of flexible substrate material.Not only free bending to change the shape,also get rid of the traditional display shape constraint,stronger,not easy to break,greatly reduce the probability of damage to the end product.
Q8:How thin and light is e-paper?
Electronic paper has a clear advantage in terms of thickness and weight,due to its simple structure and the fact that the material is based on a soft plastic film,which is as light as a featherweight.For example,a flexible e-paper display module with a 13.3-inch plastic substrate weighs about the same as 15 sheets of A4 and is about the same thickness as seven sheets of A4.
Q9:What are the common e-paper applications in daily life?
Due to the unique advantages of electronic paper,it has been applied in every field of life.For example,some bus stop signs in Shanghai have been installed with electronic paper screens to display bus routes dynamically in real time,and rely on solar energy for charging.Electronic paper shelf label replaces the traditional paper price tag,can change the price information,reduce the use of paper more environmentally friendly;Electronic paper can be seen in many applications,such as electronic paper conference board,electronic paper badge label and smart wearable.
The development and application of electronic paper technology will bring about a revolution in the field of intelligent living,so it is necessary to have a certain understanding of it in advance.After reading this article,I believe you have a more comprehensive understanding of electronic paper technology!
