DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18238203 titled 'DISPLAY DEVICE
Simplified Explanation
A display device with dual driving modes
- Sub-pixels on a substrate
- First driver for normal mode
- Second driver for high luminance mode
- Light emitting diode receives driving currents
- Potential Applications:**
- High-quality displays - Energy-efficient screens - Mobile devices
- Problems Solved:**
- Inefficient power consumption in high luminance mode - Limited luminance range in normal mode
- Benefits:**
- Improved display quality - Enhanced energy efficiency - Versatile luminance control
- Potential Commercial Applications of Dual Driving Mode Display Technology:**
- Smartphones and tablets - Televisions and monitors - Automotive displays
- Possible Prior Art:**
There are existing display technologies that use different driving modes for varying luminance levels, but the specific implementation of dual drivers in each sub-pixel may be novel.
- Unanswered Questions:**
- 1. How does the dual driving mode affect the overall lifespan of the display device?**
- The abstract does not provide information on the longevity of the display device with this dual driving mode technology. It would be important to know if this innovation has any impact on the durability of the device.
- 2. Are there any limitations to the luminance range that can be achieved with this dual driving mode technology?**
- The abstract does not mention any constraints on the luminance range that can be achieved with this technology. Understanding the boundaries of this innovation would be crucial for potential users and manufacturers.
Original Abstract Submitted
A display device can include a plurality of sub pixels disposed on a substrate; a first driver disposed in each of the plurality of sub pixels, the first driver being configured to generate a first driving current for a normal mode in which an image is displayed in a luminance range equal to or lower than a predetermined luminance; a second driver disposed in each of the plurality of sub pixels, the second driver being configured to generate a second driving current for a high luminance mode in which the luminance range is higher than the predetermined luminance; and a light emitting diode. Also, the light emitting diode is configured to receive the first driving current in the normal mode, and receive a sum of the first driving current and the second driving current in the high luminance mode.
