25‐1: A narrow border design with a new scanning circuit under low frequency AOD

With the increasing requirement for low‐power performance, especially for wearable products, 1~5Hz AOD has become the mainstream. The advantage of low‐frequency display is to reduce the power consumption of the screen, by dividing the display mode into a writing frame (Data writing frame) and a holding frame (Data keeping frame), the write frame is used for data writing and storage, the holding frame does not write data, and the stored signal is controlled to emit light, so the power consumption of the IC and the display screen is reduced by keeping part of the signal in the frame from AC clock signal to DC signal. We have developed a new scanning circuit that can output high and low frequencies to replace two sets of driver sweep circuits, the new design scheme can reduce the bezel by about 0.1mm compared with the existing solution.
