Optically driven liquid crystal displays (ODLCDs) realizes their display function by tuning the easy axis of liquid crystal (LC) molecules under polarized blue light, which has been utilized in some optical devices due to its advantages of ultra-low power consumption. However, a big issue arises in response time, i.e., the rewriting time of the ODLCD. The rewriting time of ODLCD samples was studied. Rotational viscosity plays a very important role for decreasing the rewriting time of the ODLCD. The operating temperature was changed from room temperature to nearly clearing point, the rewriting time decreased a lot as the rotational viscosity decreased for the five different kinds of the LCs. The rewriting time can be decreased from 5.2 s to 0.2 s around 25 times for the LC N4.

Measurement Results

In this paper, a new pixel structure using low-temperature polycrystalline silicon and oxide (LTPO) thin-film transistors (TFTs) for low-power liquid crystal displays (LCDs) is proposed. The extremely low off-state current of oxide semiconductor TFTs enables the proposed circuit to operate at a very low frame frequency of 1/60 Hz, so that the power consumption can be significantly reduced. In addition, the low-temperature polycrystalline silicon TFTs with high reliability directly drive pixels, which can achieve stable and flicker-free LCDs. The proposed circuit is fabricated using the LTPO TFT backplane and successfully verified by simulation and measurement results. The measurement results prove that the proposed circuit operates well without further programming for 60 s, and the power consumption in the panel (except backlight power) can be reduced to 0.02% of that of conventional LCD.

AbstractThe amorphous silicon thin transistor (a-Si TIFT) has successfully industrialized the active matrix liquid crystal displays (AMLCDs), which would get a vast market on the basis of their wide potential use for displays. Whereas, the polysilicon TFT (p-Si TFT) also has been intensely investigated and intended to realize smarter AMLCDs, with monolithic peripheral circuits.In this paper, we will discuss the applicable range of low temperature p-Si TFTs compared with high temperature p-Si TFTs. After reviewing the materials which comprise low temperature p-Si TFTs, we will introduce our self aligned aluminum gate process which could allow fast addressing even in enlarged AMLCDs in the future.

The performance of a reflective chiral-homeotropic (R-CH) liquid crystal (LC) is simulated by the dynamic parameter space method. The normally black reflective chiral-homeotropic display shows weak color dispersion, high contrast ratio, and fast response time.
