“…The display model includes ELVSS, ELVDD, source lines, TFTs, diodes and storage capacitors, while only R and C elements that would be involved in interference were shown in Figure 3 for simplicity purpose. In detail, the R and C values of source lines are 30kΩ and 30pF 6 for each lines respectively, and each unit cell has 315 lines (= 1680 × 3 / 16) in parallel. Each equivalent unit resistance of Rx and Tx sensors in a touch node were divided into two equal resistances.…”

A full‐panel circuit model of the on‐cell touch AMOLED is introduced to simulate the mutual interference between touch and display operations. The proposed panel model successfully reproduced nonlinear behaviors of the display noise observed in real systems. Also, the reverse‐directional interference, i.e., touch‐to‐display coupling, was simulated, showing that touch stimulation incurs the fluctuation of display charging voltages, possibly causing perceivable line defects. The proposed panel model can be used for various touch/display algorithms to reduce the interference effects and to determine key design parameters for new panels.

“…In TV and gaming monitor products, request for high resolution and refresh rate products is increasing. Due to the high resolution and refresh rate, the total data bandwidth transmitted from a timing controller to the display driver IC is increased 1–5 . For example, the 8K resolution display with a refresh rate of 120 Hz requires data rate for 6Gb/s for each display driver IC.…”

This paper proposes a 6Gb/s receiver for 8K displays and beyond. In the proposed receiver, a novel channel coding with 1.96% overhead is presented to guarantee minimum run-length in the clock embedded interface. It can also reduce bandwidth for effective data transmission compared to 9b/10b coding that requires 11.11% overhead. Furthermore, we present an on-chip eye margin tester that can measure the internal timing margin of receiver with only 1% area overhead. The prototype ICs are implemented using 0.18-μm HVCMOS process and evaluated in an 8K 65-in. panel.

“…Nowadays, nonlinear circuits are applied to communication and electronic systems widely (Kim et al , 2021; Kivanc and Ustun, 2021). As nonlinear circuits often contain basic nonlinear electric devices, such as capacitor, inductor, resistor and memristor (Bao et al , 2011; Kengne et al , 2017; Wu et al , 2016), which makes the process difficult to analyze the nonlinear properties by obtaining analytical solutions in most cases and so can be analyzed only numerically.…”

Purpose This paper aims to provide a symplectic conservation numerical analysis method for the study of nonlinear LC circuit. Design/methodology/approach The flux linkage control type nonlinear inductance model is adopted, and the LC circuit can be converted into the Hamiltonian system by introducing the electric charge as the state variable of the flux linkage. The nonlinear Hamiltonian matrix equation can be solved by perturbation method, which can be written as the sum of linear and nonlinear terms. Firstly, the linear part can be solved exactly. On this basis, the nonlinear part is analyzed by the canonical transformation. Then, the coefficient matrix of the obtained equation is still a Hamiltonian matrix, so symplectic conservation is achieved. Findings Numerical results reveal that the method proposed has strong stability, high precision and efficiency, and it has great advantages in long-term simulations. Originality/value This method provides a novel and effective way in studying the nonlinear LC circuit.
