DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18230665 titled 'DISPLAY DEVICE
The abstract describes a display device with a power management circuit that can operate in both normal and low power modes, providing different driving voltages to the data driver based on the mode.
- The display device includes a display panel with pixels connected to data lines.
- A power management circuit consists of a first voltage generating circuit that produces a first driving voltage for the data driver in normal mode.
- A first voltage converter generates a parking voltage lower than the first driving voltage for the data driver in low power mode.
- A second voltage converter generates a second driving voltage for the data driver in low power mode.
- A driving controller receives image data input and controls the data driver and power management circuit.
Potential Applications: - This technology can be used in various display devices such as smartphones, tablets, and monitors. - It can also be applied in automotive displays, wearable technology, and smart home devices.
Problems Solved: - Efficient power management in display devices. - Optimizing energy consumption in low power modes.
Benefits: - Extended battery life in portable devices. - Enhanced display performance with optimized driving voltages. - Reduced energy consumption and environmental impact.
Commercial Applications: Title: Energy-Efficient Display Technology for Consumer Electronics This technology can be utilized by consumer electronics manufacturers to create more energy-efficient and high-performance display devices, catering to the growing demand for sustainable and advanced technology in the market.
Questions about Energy-Efficient Display Technology: 1. How does the power management circuit optimize energy consumption in the display device?

Original Abstract Submitted
A display device comprises a display panel including a pixel connected to a data line, a power management circuit including a first voltage generating circuit which generates a first driving voltage and provides the first driving voltage to a data driver in a normal mode, a first voltage converter which generates a parking voltage less than the first driving voltage and provides the parking voltage to the data driver in a low power mode, and a second voltage converter which generates a second driving voltage and provides the second driving voltage to the data driver in the low power mode, and a driving controller configured to receive input image data and to control the data driver and the power management circuit. The data driver provides a data voltage to the data line in the normal mode and provides the parking voltage to the data line in the low power mode.
