DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240296790 titled 'DISPLAY DEVICE
The abstract describes a display device with a voltage generator that shuts down in response to a shutdown signal and includes a short circuit protection part that compares the output voltage with a reference voltage to trigger the shutdown signal.
- The voltage generator consists of a first converter that pre-charges the output voltage, maintains it, and boosts it to generate the first voltage.
- The short circuit protection part activates the shutdown signal if the output voltage falls below the reference voltage during the maintenance period.
Potential Applications: - This technology can be used in various display devices such as TVs, monitors, and smartphones. - It can also be applied in medical equipment, automotive displays, and industrial control systems.
Problems Solved: - Prevents damage to the display device in case of a short circuit. - Ensures stable voltage output for optimal performance.
Benefits: - Enhances the safety and reliability of display devices. - Improves overall efficiency and longevity of the device.
Commercial Applications: - Display device manufacturers can integrate this technology to enhance the quality and durability 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? - The short circuit protection part compares the output voltage with a reference voltage and triggers a shutdown signal if necessary, preventing damage from occurring.
2. What are the potential commercial implications of integrating this technology into display devices? - By enhancing safety and reliability, manufacturers can attract more customers and increase market share.
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.
