DISPLAY APPARATUS AND CONTROL METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18354803 titled 'DISPLAY APPARATUS AND CONTROL METHOD
Simplified Explanation
The patent application describes a display apparatus with light emitting elements that are controlled based on the temperature of the display.
- Light emitting elements are driven by current.
- A voltage control unit adjusts the driving voltage for the light emitting elements based on the temperature of the display.
- The voltage control unit ensures that the change in driving voltage per unit time stays within a predetermined limited range.
- The limited range is determined based on the relationship between the change in driving voltage and the change in light emission luminance of the light emitting elements.
Potential Applications
- Display screens for electronic devices
- LED billboards
- Automotive displays
Problems Solved
- Preventing overheating of the display
- Maintaining consistent light emission luminance
- Extending the lifespan of the display
Benefits
- Improved display performance
- Energy efficiency
- Enhanced reliability and longevity of the display
Original Abstract Submitted
A display apparatus includes light emitting elements that are driven by current and a voltage control unit that controls a driving voltage for driving the light emitting elements based on a temperature of the display apparatus. The voltage control unit performs control such that an amount of change in the driving voltage per unit time does not exceed a predetermined limited range. The predetermined limited range is determined based on a relationship between the change in the driving voltage and a change in a light emission luminance of the light emitting elements.
