Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panel brightness adjustment methods are complex and inconvenient, affecting user experience, especially in handheld devices where quick adjustments are needed to prevent eye strain.
Innovation Solution
A display panel equipped with a slide detection unit comprising independent electrodes, a sensor, and a processor that senses sliding touch actions within a preset region to determine the direction and adjust brightness accordingly, allowing for easy and quick brightness adjustments without disrupting ongoing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional menu-based brightness adjustment is used, then brightness can be adjusted, but the operation process is complex and time-consuming
Solution Approach 1:
The patent places a touch-sensitive slider at the top edge of the display, allowing users to adjust brightness immediately without navigating through menus. This preliminary positioning of the control interface enables direct interaction, eliminating the time-consuming menu navigation process while maintaining brightness adjustment functionality.
2Ease of operation
If shortcut menu is pulled down from top end of screen, then brightness can be adjusted quickly, but it affects operation of currently operated application
Solution Approach 1:
The patent extracts the brightness adjustment function from the traditional dropdown menu system and implements it as an independent touch-sensitive slider at the top edge of the display. This separation allows brightness control to operate independently without interrupting or requiring the user to exit the currently running application, thus maintaining application operation continuity while enabling quick brightness adjustment.
3Illumination intensity
If screen brightness is kept high, then display visibility is good, but eye irritation increases
Solution Approach 1:
The patent implements a dynamic brightness adjustment mechanism where the touch-sensitive slider allows users to continuously vary brightness levels according to their needs and environmental conditions. This dynamic control enables the display to adapt its illumination intensity, allowing users to reduce brightness during prolonged viewing to minimize eye irritation while maintaining good visibility when needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables seamless and rapid brightness adjustments directly within the display panel's touch region, enhancing user experience by simplifying the process and reducing eye strain.
Implementation Method 1
a sensor and a processor, wherein the slide detection unit is configured to sense a sliding touch action made by a user within a preset touch region of the display panel; the sensor is configured to sense values of currents passing through the electrodes of the slide detection unit when the sliding touch action is made by the user within the preset touch region and to send the values of the currents to the processor, the currents being generated due to the sliding touch action

AI summary
The present disclosure provides a display panel and a method of adjusting brightness thereof, and a display device. The display panel comprises a slide detection unit including at least two electrodes independent of each other, a sensor and a processor. The slide detection unit is configured to sense a sliding touch action made by a user within a preset touch region of the display panel, the sensor is configured to sense values of currents passing through the electrodes of the slide detection unit when the sliding touch action is made by the user and to send the values of currents to the processor. The currents are generated due to the sliding touch action. The processor is configured to determine a sliding direction of the sliding touch action based on the values of the currents, and to adjust screen brightness of the display panel based on the sliding direction.
