“…Many studies have developed various methods to reduce the number of source and gate driver ICs, achieve low power consumption, and improve pixel charging to satisfy the requirements of high-resolution displays; these involve enhancing the performance of pixel driving schemes [19], [20], new driving structures [21]- [25], and TFT devices [26], [27]. Tai et al proposed a new pixel circuit for TFT-LCDs that was based on a digital pulse width modulation (PWM) method [21]; it has no operational amplifiers (OP AMPs) and resistor-string digital-to-analog converters (R-DACs), reducing the power consumption of the source driver ICs.…”

However, the inserted resistor in the pixel circuit is difficult to be patterned in a sophisticated manner with TFT backplane technologies, and the RC time constant is affected by the non-uniformity of resistance, threshold voltage (V TH ) variations, and the dynamic capacitance of liquid crystal, making control of the pixel voltage difficult.…”
