With the increasing demand for portable displays, the need for displays with high energy efficiency and low power consumption is also increasing. WINSTAR promotes electronic paper display (EPD) technology, which not only offers high energy efficiency and saving features but also provides a comfortable visual experience.
Operating based on the environmental light reflection like a regular paper, EPDs provide a comfortable reading experience and maintain clarity even in direct sunlight. With a wide viewing angle (theoretically 180°), EPDs provide better contrast than other display technologies and offer a image that are close to or even better than regular print quality. There are many types of EPDs, and this article introduces the principles, applications and advantages of WINSTAR’s electro-phoretic EPD technology.
Principles of E-paper Display Technology:
E-paper Display (EPD) technology, also known as electronic ink display technology, is based on micro-capsule technology. The basic structure of an EPD consists of millions of small capsules, each containing two types of electro-phoretic particles: Negatively charged white particles and positively charged black particles are suspended in a transparent liquid.
Electrophoresis: When an electrical field is applied, the corresponding black or white particles move to the upper part of the micro-capsule, making this area visible to the user in either black or white. This is accomplished by using charged particles, as well as the principle of attraction under an electrical field.
Bistable Technology: When positive and negative electrical fields are applied to the electrodes, the charged black and white particles move and align according to the principle of attraction of different charges. When the electrical field is removed, the particle order remains constant and the image remains unchanged. When the image is updated, a different electrical field is applied to the electrodes and the particles move again, allowing the display to be refreshed. The new electrical field layout rearranges the black and white particles, and updates the display.
Product Applications:
EPD technology has a wide range of applications in various fields. WINSTAR EPD is mainly used in the following areas:
- Eye Protection Devices: Like e-book readers and laptop screens, it offers a paper-like reading experience that reduces eye strain in long-term use.
- Energy-Saving Devices: It is suitable for devices that work for a long time, such as smart watches and fitness tracking devices, extending the device’s battery life thanks to low power consumption.
- Outdoor Devices: It is suitable for providing visibility under strong light in environments with high brightness, such as electronic labels, electronic boards etc.
Advantages of WINSTAR EPD Displays:
WINSTAR energy-saving EPD displays use “bistable” technology that preserves images even when the power supply is removed and consumes power only when the image is updated. This technology offers the following advantages:
- Wide Range of Size Options: It offers a wide variety of size options from 0.97” to 13.3”.
- Ultra-low Power Consumption: It consumes power only during image updates, saving energy.
- No Backlight Required: It is lightweight, reduces energy consumption, and is suitable for long-term use.
- Wide Viewing Angle: It provides a better visual experience.
- Multiple Color Options: It offers monochrome, three-color and four-color options.
- Can Be Read In Sunlight: It is suitable for outdoor use.
- Touch Options: Touch panel models are available.
- Front Light Options: It can be equipped with front light options that adapt to different lighting environments.
- Customization Services: It offers solutions suitable for different size and special FPC (flexible circuit board) requirements.
EPD technology offers significant energy saving advantages by focusing on energy efficient displays. EPD displays offer efficient, energy-saving and environmentally friendly solutions with advanced technology and various applications. These displays have become a preferred option in the market for various fields of use. Whether it is daily applications or professional environments, energy efficient EPD technology continues to offer valuable and innovative solutions.
