PIXEL CIRCUIT, DRIVING METHOD, DISPLAY SUBSTRATE AND DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17434709 titled 'PIXEL CIRCUIT, DRIVING METHOD, DISPLAY SUBSTRATE AND DISPLAY DEVICE
Simplified Explanation
The patent application describes a pixel circuit for a display device that prevents light emission issues during initialization. The circuit includes a driving circuit, a light-emitting control circuit, a light-emitting element, and two initialization circuits.
- The first initialization circuit writes an initialization voltage to the control terminal of the driving circuit under the control of a first initialization control signal.
- The second initialization circuit writes an initial data voltage to the anode of the light-emitting element under the control of a second initialization control signal.
- This prevents light emission from leakage current and lateral leakage at low gray scales that occur during the initialization of the light-emitting element's anode.
Potential Applications
- This technology can be applied in various display devices such as televisions, computer monitors, and mobile devices.
- It can improve the overall image quality and prevent issues related to light emission during initialization.
Problems Solved
- The technology solves the problem of light emission from leakage current and lateral leakage during the initialization of the light-emitting element's anode.
- It ensures accurate and consistent display performance, especially at low gray scales.
Benefits
- Prevents light emission issues during initialization, improving the overall image quality.
- Ensures accurate and consistent display performance, even at low gray scales.
- Enhances the user experience by providing a high-quality display with minimal visual artifacts.
Original Abstract Submitted
A pixel circuit, a driving method, a display substrate, and a display device are provided. The pixel circuit includes a driving circuit, a first light-emitting control circuit, a light-emitting element, a first initialization circuit, and a second initialization circuit. The first initialization circuit writes, under the control of a first initialization control signal, an initialization voltage provided by an initialization voltage line, to a control terminal of the driving circuit; the second initialization circuit writes, under the control of a second initialization control signal provided by a second initialization control line, an initial data voltage provided by an initial data line, to an anode of the light-emitting element. Light emission of the light-emitting element from a leakage current and lateral leakage at low gray scales caused when initializing the anode of the light-emitting element can be prevented.
