Abstract. This paper reports transient response characteristics of active-matrix organic light emitting diode (AMOLED) displays for mobile applications. This work reports that the rising responses look like saw-tooth waveform and are not always faster than those of liquid crystal displays. Thus, a driving technology is proposed to improve the rising transient responses of AMOLED based on the overdrive (OD) technology. We modified the OD technology by combining it with a dithering method because the conventional OD method cannot successfully enhance all the rising responses. Our method can improve all the transitions of AMOLED without modifying the conventional gamma architecture of drivers. A new artifact is found when OD is applied to certain transitions. We propose an optimum OD selection method to mitigate the artifact. The implementation results show the proposed technology can successfully improve motion quality of scrolling texts as well as moving pictures in AMOLED displays.

LCDs(Liquid Crystal Displays) have displaced cathode ray tube(CRT) displays in most applications, however motion blur is one of the main challenges for using LCDs in television applications. LCD motion blur is caused jointly by the slow LCD's temporal response and the hold-type LCD's rendering method together with the motion pursuing function and the temporal low-pass filter characteristic of human visual system(HVS). Although LCD motion blur has been addressed extensively in the literature, there are a few of LCD motion blur models. In this paper, we show an effective blind modeling method for LCD motion blur. Simulation and perceptual tests indicate that our model is indeed effective at reducing the amount of motion blur on LCDs .

“…The images might be seen intermittently by the eyes; however, if the screen's refresh rate is fast enough, the human visual system perceives and maintains the image for the entire frame time. 2,3 Therefore, even if the eye ball rotates to track a moving object, the human visual system perceives the image at its expected location causing minimal spatio-temporal integration discrepancy.…”

Abstract— An impulsive driving technique has been widely adopted for the elimination of motion blur in LCDs. Although the problem of slow temporal response time is very well known for LCDs, the inherent motion blur of moving objects in hold‐type displays has a more‐serious impact on display performance. It is well known that even very fast LCDs with zero response time still suffer from the motion‐blur artifact due to hold‐type driving effects. However, a fast temporal response is also critical in order to maximize the blur‐reduction effect even in the case of impulsive driving. In this paper, the special behavior of LC molecules in an impulsive driving environment has been analyzed especially for the case of black‐frame insertion, and we propose an effective means to implement optimized response‐time compensation (RTC) for the black‐frame insertion technique.
