DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18547680 titled 'DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes a display panel with light-emitting pixels, a timing control unit that adjusts the driving frame frequency of the display panel based on the input frame frequency of digital video data, and a data driving unit that outputs data voltages according to the digital video data.
- The display panel operates at a higher first frame frequency for a first frame period and at a lower second frame frequency for a second frame period, which includes a data addressing period and a blank period.
- During the data addressing period, data voltages corresponding to each pixel are applied, while during the blank period, no data voltage is applied, and an initialization voltage is applied to the first electrode of a light-emitting element.
Potential applications of this technology:
- High-quality displays for televisions, monitors, and mobile devices.
- Virtual reality and augmented reality headsets.
- Medical imaging devices.
Problems solved by this technology:
- Improving display quality by adjusting frame frequency based on input video data.
- Enhancing energy efficiency by optimizing the driving frame frequency.
Benefits of this technology:
- Enhanced visual experience with smoother motion and reduced flickering.
- Energy savings through efficient frame frequency adjustment.
- Improved performance and longevity of display panels.
Original Abstract Submitted
A display device includes: a display panel including pixels having light-emitting elements; a timing control unit for variably changing the driving frame frequency of the display panel according to the input frame frequency of digital video data; and a data driving unit for outputting data voltages according to the digital video data, wherein the display panel operates at a first frame frequency for a first frame period and operates at a second frame frequency, which is lower than the first frame frequency, for a second frame period, the second frame period includes a data addressing period in which a data voltage corresponding to each of the pixels is applied to the pixels, and a blank period in which no data voltage is applied to each of the pixels, and the blank period includes a period of initializing a first electrode of a light-emitting element into an initialization voltage.
