67‐3: Development of the Novel Wearable AMOLED Display

The 1.43” hybrid wearable AMOLED display (HWAD) had been developed based on low‐temperature polycrystalline silicon (LTPS) and thin‐film encapsulation (TFE) techniques, which was integrated touch and display functionalities with one driver IC. The 1.43” HWAD border was similar to flexible products, but less than rigid ones above 20%. Meanwhile, the ultra‐thin stack‐up module thickness was also close to that of flexible ones, but reduced about 31.4% compared to traditional rigid display. HWAD utilized a new pixel compensation circuit and a novel compensation algorithm, eventually achieved a flicker indicator FMA value of <3% in 5Hz AOD mode. The logic power consumption of the smart watch in 5Hz AOD model is reduced about 35% compared with the one in 30Hz. The novel HWAD aggregated the advantages of flexible and rigid displays with low process costs. The novel high‐performance HWAD had significant market application prospect.
