The paper presents three novel solutions for driving OLED displays including Distributive‐Driving, Prime‐Bridge, and the combination thereof. Distributive‐Driving re‐arranges the source and gate channel numbers on the back plane without changing the OLED fine metal mask (FMM) pattern, thereby increasing charging time, reducing fan‐out area, etc. Prime‐Bridge enables the sharing of the driving circuit by multiple subpixels and thus, can reduce the total number of thin‐film transistors (TFTs) and capacitors as well as the gate line number without sacrificing the charging time of each subpixel and the frame rate. By combining Distributive‐Driving and Prime‐Bridge, the driving circuit area can be increased in both horizontal and vertical directions, which is good for high PPI backplane design and can reduce BOM cost with higher yield.
