Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic ink screens with charged black and white ink particles experience slow refreshing speeds and long response times due to interference between particles of different colors during movement.
Innovation Solution
An electronic ink screen design featuring independent ink accommodating cavities with uniformly charged ink particles that utilize electric fields in different directions to control particle movement, allowing for rapid color transitions without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If black ink particles and white ink particles with different charges are used in the electronic ink layer, then the electronic ink screen can present clear black and white visualization effect, but the black ink particles and white ink particles interfere with each other when moving, resulting in slow refreshing speed and long response time
Solution Approach 1:
The patent divides the ink particles into separate groups based on their charge polarity. All black ink particles have the same charge (e.g., negative charge), and all white ink particles have the opposite charge (e.g., positive charge). This segmentation eliminates the interference between differently charged particles while maintaining the black and white visualization effect through uniform particle movement responses to applied electric fields.
2Illumination intensity
If black ink particles and white ink particles with different charges are used in the electronic ink layer, then the electronic ink screen can present clear black and white visualization effect, but the response time of the electronic ink screen becomes long
Solution Approach 1:
The patent segments the ink particle population into uniformly charged groups (all black particles with one charge, all white particles with opposite charge). This segmentation ensures that when an electric field is applied, particles of the same color move in unison without being disrupted by opposing charge interactions, thereby reducing the time required to achieve the desired display state.

AI summary
Embodiments of this application provides an electronic ink screen and a display apparatus. The electronic ink screen includes at least the following which are stacked: a first conductive substrate, an ink display layer and a second conductive substrate. The ink display layer is located between the first conductive substrate and the second conductive substrate, and the second conductive substrate is located above the first conductive substrate. The ink display layer has a plurality of ink accommodating cavities that are mutually independent. A plurality of ink particles that have a same color are provided in the ink accommodating cavity. The ink particles are used for displaying a first color. The electronic ink screen further includes a function layer. The function layer is configured to display a second color. The function layer is located at a side that is of the ink display layer and that faces away from the second conductive substrate. Embodiments of this application can improve a refreshing speed of the electronic ink screen, thereby reducing a response time of the electronic ink screen.
