E paper display list
E-ink screens are suitable for scenes that need to display fixed images for a long time, use ambient light and low power consumption
No flicker, no blue light, no eye damage
E-paper uses the same environmental light source as paper without luminescence, minimizing the intensity of eye use and protecting vision.
large viewing angle
E-paper has a 178-degree viewing angle, so it can be seen clearly from any angle
Ultra low power consumption
E-paper only consumes power when refreshing the drawing, allowing for ultra-long runtime in scenarios where frequent refreshing is not required, or battery-free operation.
The principle of electronic ink screen display
1. Due to the different charged properties (positive/negative), particle shape and size, their moving directions and moving speeds are also different in a certain electric field, so they can be separated.
2. When the electric field is set positive, the white particles move to the top of the microcapsules, thus appearing white. At the same time, the black particles are drawn to the bottom of the microcapsules, thereby hiding them. When an opposite electric field is applied, black particles appear at the top of the capsule, thus appearing black.
E-ink display features
No flicker, no blue light, no eye damage
1. The LCD screen refreshes the display screen at a high frequency and is always in a blinking state. At the same time, the backlight directly enters the eyes (especially blue light), causing damage to the eyes.
2. The ink screen uses ambient light source and does not emit light like a book (as shown in Figure 2, which is basically the same as the spectrum of natural light), which reduces the intensity of the eyes to the greatest extent and protects eyesight.
LCD screen
Electronic Ink Screen
Close to paper reading experience, suitable for long time reading
1. The ink screen has almost no viewing angle limitation (viewing angle > 178 ﾟ)
2. High reflectivity, high contrast value, suitable for outdoor and long-time reading
Long battery life, no power consumption when the screen is still and not refreshed
1. Static display does not require electricity to maintain, only consumes a small amount of electricity when the screen changes.
Ultra-low power consumption, large viewing angle，Strong light visible
Electronic paper has a very big advantage in the case of not needing to refresh frequently
