DISPLAY DEVICE AND METHOD OF DRIVING DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18079895 titled 'DISPLAY DEVICE AND METHOD OF DRIVING DISPLAY DEVICE
Simplified Explanation
The patent application describes a display device that includes a display panel with multiple pixel rows, a power supply, and an overcurrent protector. The overcurrent protector shuts down the power supply if any of the pixel rows are burnt.
- The overcurrent protector includes a sensing controller that measures the current of at least one pixel row in two different frame periods.
- If the current in the first frame period is equal to or greater than a threshold value, the sensing controller measures the current again in the second frame period.
- A burnt determiner then determines if the pixel row is burnt based on the current measurements.
- If the pixel row is burnt, a shutdown signal is sent to the power supply to prevent further damage.
Potential applications of this technology:
- Display devices such as televisions, computer monitors, and smartphones.
- Any application that uses a display panel with pixel rows.
Problems solved by this technology:
- Prevents further damage to the display panel when pixel rows are burnt.
- Ensures the power supply is shut down to avoid potential hazards.
Benefits of this technology:
- Increases the lifespan of the display panel by preventing further damage.
- Enhances safety by shutting down the power supply when necessary.
Original Abstract Submitted
A display device may include a display panel including a plurality of pixel rows, a power supply providing a power voltage to the display panel, and an overcurrent protector shutting down the power supply when at least one of the pixel rows is burnt. The overcurrent protector may include a sensing controller sensing a first current of at least one first pixel row of the display panel in a first frame period, and sensing a second current of the first pixel row in a second frame period after the first frame period when the first current is greater than or equal to a first threshold value. The overcurrent protector may further include a burnt determiner determining whether the first pixel row is burnt, and providing a shutdown signal to the power supply when the first pixel row is burnt.
