“…Fig. 4 shows a single sub-pixel of the proposed pixel circuit, of which the pixel area is 49.6 µm × 74.5 µm, as determined from the sub-pixel rendering [17]; its corresponding parameters are presented in Table 1. Also, C1 is a storage capacitor that stores the desired driving voltage, so the capacitance of C1 is much greater than that of C2, which is a coupling capacitor to boost V D to generate the leakage current that compensate for the voltage drops in V A .…”

This work proposes a new pixel circuit for active-matrix organic light-emitting (AMOLED) smartwatch displays with a low frame rate. Within the long emission period, the leakage current of a lowtemperature polycrystalline silicon thin-film transistor (LTPS TFT) is reduced to suppress the distortion of the driving voltage at the gate node of the driving TFT. Based on the measured electrical characteristics of a fabricated p-type LTPS TFT, the HSPICE model is established to verify the feasibility of the proposed circuit. The analytical results indicate that the relative OLED current error rates are all below 4.73%, as the threshold voltage of TFT varies by ±0.5 V. Notably, the OLED current varies by only 2.94% during the emission period of 66.7 ms at a medium gray level, demonstrating the effectiveness of the leakage prevention scheme. INDEX TERMS Active-matrix organic light-emitting diode (AMOLED), low-temperature polycrystalline silicon thin-film transistors (LTPS TFTs), leakage current prevention.

“…Unlike with OLEDs, properly engineered microLEDs are not hampered by the Achille's heel of a primary‐color channel (blue 1 ), which is much less robust than the other two. There is no need to reduce the spatial resolution of two of the three primary channels, such as in so‐called “diamond pixels,” 2 to reduce current density and device stress.…”

Several normal sub pixel arrangements were introduced in this paper, including RGB Stripe and PenTile RGBG. The paper compared the advantage and disadvantage of each arrangement. The pixel of PenTile RGBG includes only two color channels, which causing the color leakage and image distortion. To solve this problem, two novel arrangements after light interleaved and light overlapped based on lens refraction were proposed. The results of image test and contrast experiment showed that the improved sub pixel arrangement can weaken color artifacts effectively.
