“…The touch sensing only in the vertical blank showed the unnatural representations of moving touch actions and there was the difficulty in achieving the higher touch reporting rate than the display frame rate. Therefore, the touch sensing intervals have been inserted in the middle of the display scanning operation as depicted in Figure 19 [115][116][117][118][119]. It is called a time division driving method (TDDM).…”

Many advanced technologies have been employed in the high performance active matrix displays including liquid crystal displays, organic light emitting diode displays, and micro light emitting diode displays. On the other side, there have existed the strong demand on the cost reduction and it is one of low cost schemes to integrate the driver circuit in a panel based on thin film transistor technologies. This paper reviews overall concept, operation principles, and various circuit approaches in shift registers for the scanning pulse generation. In addition, it deals with the implementation of additional functionalities in gate drivers to support pixel compensation, multi-line driving, in-cell capacitive touch screen, pixel sensing, and adaptive scanning region control.

A compact gate driver on array (GOA) was proposed for Micro‐Light Emitting diodes (Micro‐LED) display based on progressive‐mode pulse‐width modulation (PWM) using low‐temperature‐polysilicon (LTPS) thin‐film transistors (TFTs). Thanks to outputting line‐by‐line scanning (Scan) and emission control signals (EM) to address switching‐and emission‐transistors in Micro‐LED pixel circuit, the proposed GOA circuit enables an increased emission time by 60% with the frame rate of 120 Hz, compared with the conventional GOA circuit of simultaneous operating mode. Furthermore, the pulse‐width of EM signals are programmable simply by adjusting the number of input pulses.

A compact gate driver using p‐type low‐temperature polycrystalline silicon (LTPS) thin‐film transistors (TFTs) was proposed for Micro‐Light Emitting diodes (μLEDs) display using progressive emission analog pulse‐width modulation (A‐PWM) approach. The gate driver contains a simple waveform shaping module and outputs multiple sweep signals, including SW[n], EM[n], and S[n], by reusing the bootstrap node. Compared with conventional schemes, the proposed gate driver renders static power consumption reduction of the μLED display by 29.2%.
