The proposed digital pixel circuit also has advantages in circuit layout compared with analog pixel circuits.
One has the same pixel interval between adjacent pixels as the square lattice, which results in higher resolution than the square one.
Pixel replication is shown to be significantly more accurate compared with other approaches.
In order to further reduce the pixel size and to improve device sensitivity, we propose a new pixel structure.
In this paper an improved version of pixel sieve method is proposed to achieve more security then existing pixel sieve method.
The proposed methodology has given better results in recognition over square pixel based approaches.
It is shown that the average nonuniformity of the OLED current for the proposed pixel circuit is 5.7% compared with 85.7% for the conventional 2T1C pixel circuit, and thus, the brightness uniformity of AMOLED displays can be enhanced.
The results show that improved performance is obtained when applying the Gaussian pixel-weighting marks technique, compared to other techniques, namely the equal gain pixel-weighting and the no pixel-weighting marks techniques.
