==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.
