DISPLAY DEVICE INCLUDING OVERLOAD PROTECTION CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18403923 titled 'DISPLAY DEVICE INCLUDING OVERLOAD PROTECTION CIRCUIT
Simplified Explanation
The display device described in the patent application includes a display, a first power module, and a second power module. The first power module supplies a first power, while the second power module supplies a second power to the display. The first power module is designed to cut off the first power in case the input current exceeds a certain threshold, identify abnormalities in the second power module based on the second power output, and adjust the overload criterion in case of abnormality in the second power module.
- Explanation of the patent:
* Display device with two power modules supplying power to the display. * First power module cuts off power if input current exceeds threshold. * Identifies abnormalities in second power module based on second power output. * Adjusts overload criterion in abnormal state of second power module.
- Potential Applications:**
This technology could be applied in various display devices such as televisions, monitors, and digital signage systems.
- Problems Solved:**
1. Prevents damage to the display by cutting off power in case of excessive input current. 2. Identifies abnormalities in the second power module to ensure proper functioning of the display.
- Benefits:**
1. Enhanced safety by preventing potential damage to the display. 2. Improved reliability of the display device by detecting abnormalities in the power modules.
- Potential Commercial Applications:**
Optimizing Power Management in Display Devices for Enhanced Safety and Reliability
- Possible Prior Art:**
There may be prior art related to power management systems in display devices, but specific examples are not provided in this context.
- Unanswered Questions:**
- 1. How does the display device differentiate between normal and abnormal states of the second power module based on the second power output?**
The patent application mentions that the first power module can identify abnormalities in the second power module, but it does not elaborate on the specific criteria or methods used for this differentiation.
- 2. What are the specific threshold current amounts for the first and second overload criteria mentioned in the patent application?**
The application mentions changing the overload criterion from a first threshold current amount to a second threshold current amount, but it does not specify the actual values of these threshold amounts.
Original Abstract Submitted
A display device according to an embodiment includes a display, a first power module that outputs a first power, and a second power module that outputs a second power. The first power and the second power are supplied to the display. The first power module is configured to cut off the first power when an amount of input current exceeds an overload criterion, to identify whether the second power module is abnormal based on the second power, and to change the overload criterion from a first threshold current amount to a second threshold current amount that exceeds the first threshold current amount, in an abnormal state of the second power module
