DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18369842 titled 'DISPLAY DEVICE
The patent application describes a display device with a voltage generator that shuts down in response to a shutdown signal and includes short circuit protection.
- The voltage generator has a first converter that generates a first voltage from an input voltage.
- A first short circuit protection part compares the output voltage with a reference voltage and triggers the shutdown signal if the output voltage is too low.
- The first converter pre-charges the output voltage, maintains it, and then boosts and outputs it as the first voltage in different periods.
Potential Applications:
- This technology can be used in various display devices such as TVs, monitors, and smartphones.
- It can also be applied in medical devices, automotive displays, and industrial control systems.
Problems Solved:
- Prevents damage to the display device from short circuits.
- Ensures stable voltage output for optimal performance.
Benefits:
- Enhanced safety features for display devices.
- Improved reliability and longevity of the devices.
- Efficient power management leading to energy savings.
Commercial Applications:
- Manufacturers of display devices can integrate this technology to enhance the safety and performance of their products, gaining a competitive edge in the market.
Questions about the technology: 1. How does the short circuit protection part prevent damage to the display device? 2. What are the potential energy savings associated with this technology?
Frequently Updated Research: There may be ongoing research on improving the efficiency and effectiveness of short circuit protection in display devices. Stay updated on industry publications and conferences for the latest advancements in this field.
Original Abstract Submitted
Disclosed is a display device which includes a voltage generator including a first converter that generates a first voltage using an input voltage and is shut down in response to a shutdown signal and a short circuit protection part including a first short circuit protection part that compares an output voltage of an output terminal of the first converter with a first reference voltage and outputs the shutdown signal. The first converter pre-charges the output voltage to a predetermined voltage level during a first period, maintains a level of the output voltage during a second period subsequent to the first period, and boosts and outputs the output voltage as the first voltage during a third period subsequent to the second period. The first short circuit protection part outputs the shutdown signal when the output voltage in the second period has a level lower than that of the first reference voltage.
