Abstract
An electronic device includes a display panel, a first timing controller, and a second timing controller. The first timing controller generates a first error flag signal, the second timing controller generates a second error flag signal, and the first timing controller and the second timing controller exchange the first error flag signal and the second error flag signal with each other. The first timing controller controls a first completion signal, and the second timing controller controls a second completion signal. When the first completion signal is activated and the second completion signal is activated, the first timing controller and the second timing controller drive the first display region and the second display region of the display panel.
Claims20
An electronic device comprising:
- a display panel including a first display region and a second display region adjacent to the first display region;
- a first timing controller configured to drive the first display region;
- and
- a second timing controller configured to drive the second display region,
- wherein the first timing controller determines a first error state of the first display region and generates a first error flag signal indicating the first error state,
- wherein the second timing controller determines a second error state of the second display region and generates a second error flag signal indicating the second error state,
- wherein the first timing controller and the second timing controller exchange the first error flag signal and the second error flag signal with each other,
- wherein the first timing controller deactivates a first completion signal when at least one of the first error flag signal and the second error flag signal is activated,
- wherein the second timing controller deactivates a second completion signal when at least one of the second error flag signal and the first error flag signal is activated, and
- wherein the first timing controller and the second timing controller drive the first display region and the second display region of the display panel, respectively when the first completion signal is activated and the second completion signal is activated.
An electronic device comprising:
- a display panel including a first display region and a second display region adjacent to the first display region;
- a first timing controller configured to drive the first display region;
- a second timing controller configured to drive the second display region;
- and
- a processor configured to drive the first timing controller and the second timing controller,
- wherein the first timing controller determines a first error state of the first display region and generates a first error flag signal indicating the first error state,
- wherein the second timing controller determines a second error state of the second display region and generates a second error flag signal indicating the second error state,
- wherein the first timing controller and the second timing controller provide the first error flag signal and the second error flag signal to the processor,
- wherein the processor is configured to:
- deactivate a completion signal when at least one of the first error flag signal and the second error flag signal is activated, and
- wherein the processor is configured to drive the first display region and the second display region of the display panel, respectively, when the completion signal is activated.
