DISPLAY DEVICE AND METHOD OF DRIVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18124044 titled 'DISPLAY DEVICE AND METHOD OF DRIVING THE SAME
Simplified Explanation
The patent application describes a display device with various components to monitor and control the display panel.
- The display panel shows an image and consists of pixels.
- The driving voltage controller has an overcurrent detector that generates an alert signal when the driving current exceeds a reference current.
- The load calculator calculates the load of input image data when the alert signal is received and generates a load escape signal if the load is higher than a reference load.
- The vertical blank counter counts the time of a vertical blank period when both the alert signal and load escape signal are present, and generates a counter escape signal if the count value exceeds a reference count value.
- The driving voltage generator adjusts the driving voltage provided to the display panel based on the alert signal and the counter escape signal.
Original Abstract Submitted
A display device may include a display panel displaying an image and including pixels, a driving voltage controller including an overcurrent detector generating an alert signal when a driving current of the display panel is greater than a reference current, a load calculator calculating a load of input image data in response to the alert signal and generating a load escape signal when the load is greater than a reference load, a vertical blank counter generating a vertical blank count value by counting a time of a vertical blank period in response to the alert signal and the load escape signal, and generating a counter escape signal when the vertical blank count value is greater than a reference count value, and a driving voltage generator altering a driving voltage provided to the display panel in response to the alert signal and the counter escape signal.
