DISPLAY APPARATUS AND DRIVING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18382286 titled 'DISPLAY APPARATUS AND DRIVING METHOD THEREOF
Simplified Explanation
The display apparatus described in the patent application includes a display panel, a backlight unit, a backlight driver, a memory, and a processor.
- The backlight driver drives the backlight unit by identifying a dimming section corresponding to a variable refresh rate of an image based on a sync signal.
- The processor executes instructions stored in the memory to identify the output frequency of the sync signal and output it to the backlight driver at a higher frequency.
- The backlight unit is then driven based on the variable refresh rate of the image, as indicated by the sync signal in the higher frequency.
---
- Potential Applications of this Technology
- This technology can be used in high refresh rate displays such as gaming monitors and VR headsets.
- It can also be applied in televisions and mobile devices to improve image quality and reduce motion blur.
- Problems Solved by this Technology
- Traditional displays may not be able to adjust the backlight brightness quickly enough to match the variable refresh rate of the image, leading to motion blur and image artifacts.
- By driving the backlight unit based on the sync signal in a higher frequency, this technology ensures that the backlight brightness is adjusted accurately and in real-time.
- Benefits of this Technology
- Improved image quality with reduced motion blur and ghosting effects.
- Enhanced viewing experience for users, especially in fast-paced content such as gaming and sports.
- Energy efficiency by dynamically adjusting the backlight brightness according to the content being displayed.
Original Abstract Submitted
Provided is a display apparatus including: a display panel, a backlight unit configured to output light, a backlight driver configured to drive the backlight unit by identifying a dimming section of the backlight unit corresponding to a variable refresh rate of an image, based on reception of a sync signal, a memory storing at least one instruction, and at least one processor configured to execute the at least one instruction. The display apparatus is configured to identify a first output frequency of a sync signal that varies based on the variable refresh rate of the image, output the sync signal to the backlight driver in a second output frequency that is a higher frequency than the first output frequency, based on predetermined information, and drive the backlight unit corresponding to the variable refresh rate of the image, based on receiving the sync signal in the second output frequency.
