DRIVING DEVICE AND DRIVING METHOD OF ELECTROLUMINESCENT DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240212539 titled 'DRIVING DEVICE AND DRIVING METHOD OF ELECTROLUMINESCENT DISPLAY APPARATUS
The driving device of an electroluminescent display apparatus described in the abstract includes a pixel line determiner, an over driving control controller, and a sensing and driving circuit.
- The pixel line determiner selects a representative pixel line with the largest accumulation stress from among all pixel lines.
- The over driving control controller selects a sample pixel characteristic value from the representative pixel line and outputs control signals based on the magnitude of the sample value.
- The sensing and driving circuit pre-senses pixel characteristic values in the first sensing period, performs ODC sensing in the second sensing period, and repeats ODC sensing multiple times based on the control signals.
Potential Applications: - This technology can be used in various display devices such as TVs, monitors, and digital signage. - It can also be applied in automotive displays, wearable technology, and medical imaging equipment.
Problems Solved: - Reduces accumulation stress on pixels caused by repetitive display of images. - Improves overall display performance and longevity of the device.
