DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240242673 titled 'DISPLAY DEVICE
The abstract describes a display device that improves image quality by reducing parking voltage mura and enhancing the uniformity of the display panel.
- The display device includes a display panel with pixels connected to data and gate lines, a data driver for applying data and parking voltages, a gate driver for scan signals, a light-emission signal generator, and a controller operating based on different bands with varying luminance levels.
- In at least one band, the duty ratio of the light-emission signal is smaller than the duty ratio of the parking voltage, reducing parking voltage mura and improving display panel uniformity.
- This innovation enhances image quality by minimizing inconsistencies in brightness across the display panel.
Potential Applications: - This technology can be applied in various display devices such as TVs, monitors, and smartphones to enhance image quality. - It can also be used in public displays, digital signage, and automotive displays for improved visual performance.
Problems Solved: - Addresses the issue of parking voltage mura, which can lead to uneven brightness levels on the display panel. - Improves the uniformity of the display panel, resulting in a more consistent and high-quality visual experience.
Benefits: - Enhanced image quality with reduced parking voltage mura. - Improved uniformity of the display panel for a more consistent viewing experience. - Increased overall performance and visual appeal of display devices.
Commercial Applications: - This technology can be valuable for manufacturers of display devices looking to enhance the quality and performance of their products. - It can be utilized in various commercial settings where high-quality displays are essential, such as retail stores, control rooms, and entertainment venues.
Questions about the technology: 1. How does the reduction of parking voltage mura impact the overall image quality of the display device? 2. What are the specific factors that contribute to the improved uniformity of the display panel with this technology?
Original Abstract Submitted
a display device includes a display panel including a plurality of pixels connected to a data line and a gate line; a data driver configured to apply a data voltage to the data line for an active period and to apply a parking voltage to the data line for a blank period for which the data voltage is not applied; a gate driver for applying a scan signal to the gate line; a light-emission signal generator for applying a light-emission signal to the plurality of pixels; and a controller configured to operate the display device based on a plurality of bands, wherein the plurality of bands have different highest target luminance levels based on operating environments of the display device, wherein in at least one of the plurality of bands, a duty ratio of the light-emission signal is smaller than a duty ratio of the parking voltage. thus, parking voltage mura is reduced and uniformity of the display panel is improved to improve image quality.
