“…While the internal compensation is categorized into voltage programming and current programming for the compensation of the TFT variation [120][121][122][123][124], the external compensation scheme can address TFT variations as well as OLED degradation to meet the requirement of the long life time in large display applications. The pixel circuits based on external compensation methods includes a sensing TFT (N3) to sense the characteristics of TFTs (N2) and OLEDs as described in Figure 21 [125][126][127]. After the full scanning for a frame of the image is finished, the sensing operation for pixels of one line is conducted in the vertical blank to secure enough sensing time.…”

Many advanced technologies have been employed in the high performance active matrix displays including liquid crystal displays, organic light emitting diode displays, and micro light emitting diode displays. On the other side, there have existed the strong demand on the cost reduction and it is one of low cost schemes to integrate the driver circuit in a panel based on thin film transistor technologies. This paper reviews overall concept, operation principles, and various circuit approaches in shift registers for the scanning pulse generation. In addition, it deals with the implementation of additional functionalities in gate drivers to support pixel compensation, multi-line driving, in-cell capacitive touch screen, pixel sensing, and adaptive scanning region control.

“…In addition, external compensation is essential by using an OLED panel with a good high dynamic range. Therefore, in order to secure time for external compensation, a sufficient vertical blank period is required [1]. To meet these requirements, a minimum data rate should be reached to about 12Gbps per lane.…”

This paper proposes a 6Gbps receiver for 8K 240Hz OLED display. In the proposed receiver, video image compression is presented to double the effective data bandwidth. In addition, it proposes dual path CTLE offset voltage calibration and CTLE adaptation with eye margin tester to implement 6Gbps receiver. The prototype IC is implemented in a 0.18μm HVCMOS process and is evaluated as an 8K 65‐inch panel.
