Abstract
Provided are display apparatuses and methods of operating the same. In a display apparatus, a display image may be continuously held for longer than about 10 msec after the power of the display panel is turned off. The display apparatus may indicate a liquid crystal display (LCD) apparatus including an oxide thin film transistor (TFT). Off leakage current of the oxide TFT may be less than about 10−14 A.
Claims19
A display apparatus comprising:
- a first substrate including a TFT (thin film transistor) and a pixel electrode connected to the TFT, the TFT configured to maintain a display image for longer than about 10 ms after switching to an off-state;
- a second substrate including a common electrode facing the first substrate;
- and
- a liquid crystal layer between the first substrate and the second substrate.
