DISPLAY APPARATUS HAVING BACK-LIGHT UNIT AND LIQUID CRYSTAL PANEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18541340 titled 'DISPLAY APPARATUS HAVING BACK-LIGHT UNIT AND LIQUID CRYSTAL PANEL
Simplified Explanation
The display apparatus described in the patent application includes a viewing angle control unit with light-blocking patterns and variable patterns that can change their transmittance based on applied voltage, allowing for selective sharing of the displayed image without distracting people around the user.
- The display apparatus includes a liquid crystal panel and a back-light unit.
- A viewing angle control unit is positioned between the back-light unit and the liquid crystal panel.
- The viewing angle control unit consists of light-blocking patterns with a light-blocking material and variable patterns located between a first control electrode and a second control electrode.
- The variable patterns extend perpendicularly to the light-blocking patterns and can adjust their transmittance based on the voltage applied to the control electrodes.
Potential Applications
The technology could be applied in:
- Public displays
- Security monitors
- Gaming devices
Problems Solved
The technology helps prevent distractions to people around the user by selectively sharing the displayed image.
Benefits
- Improved privacy for users
- Enhanced viewing experience in public settings
- Customizable display options
Potential Commercial Applications
"Privacy-Enhancing Display Technology for Public Use"
Possible Prior Art
There may be prior art related to privacy filters for displays or adjustable transmittance technologies in liquid crystal panels.
Unanswered Questions
1. How does the technology impact the overall brightness and clarity of the displayed image? 2. What are the potential limitations or challenges in implementing this technology on a larger scale?
Original Abstract Submitted
A display apparatus includes a liquid crystal panel disposed on a back-light unit; and a viewing angle control unit disposed between the back-light unit and the liquid crystal panel, wherein the viewing angle control unit includes light-blocking patterns having a light-blocking material and variable patterns disposed between a first control electrode and a second control electrode, wherein the variable patterns are extended in a direction perpendicular to the light-blocking patterns, and wherein transmittance of each variable pattern is changed according to a voltage applied to the first control electrode and the second control electrode, thereby preventing a distraction of people around a user by selectively sharing a realized image.
