P‐62: AMOLED Fast Electrical Detection Technology and Compensation Data Processing

The electrical compensation scheme in the field of AMOLED (Active Matrix Organic Light Emitting Diode) has unique advantages. Compared with the traditional internal compensation circuit, the electrical compensation scheme can make the pixel circuit more concise, so that higher Pixels Per Inch (PPI) can be achieved. At the same time, it is more excellent in extending the life of the display and improving the display effect in real time. We use the current mode detection scheme, compared with the voltage mode detection technology, has a faster detection speed, in terms of compensation object is not limited to TFT Vth, but any factor caused by the driving TFT current difference, so it has higher technical advancement.
