Publication number: 20260301641Abstract: A multistable display with a handwriting function includes a timing controller circuit unit, a driver circuit unit, and a display panel unit. When the driver circuit unit receives a digital to analog (d2a) signal, the driver circuit unit generates a pixel electrode driver signal outputted to the display panel unit according to a handwriting pixel electrode header setting data and a handwriting pixel electrode waveform data. The driver circuit unit can use the handwriting pixel electrode waveform data with fewer bits, in conjunction with the handwriting pixel electrode header setting data, to determine a voltage value of the pixel electrode driver signal outputted to the display panel unit.

Patent number: 12725582Abstract: A multistable display includes a timing controller circuit, a driver circuit, and a panel. The timing controller circuit generates a time controller signal. The time controller signal includes a header setting signal and a voltage waveform data. The driver circuit stores a voltage configuration truth table, configures the voltage configuration truth table according to the header setting signal, and determines a driver voltage waveform outputted to the panel according to the voltage waveform data and the voltage configuration truth table. As the driver voltage waveform is transmitted by only 1-bit binary code, an amount of bits needed to transport is therefore drastically decreased. Namely, under a same condition of transporting a same amount of bits within a same time, the driver circuit can drive the panel at a lower clock rate, thus decreasing power consumption.Type: GrantFiled: September 19, 2025Date of Patent: September 1, 2026Assignee: GENETOUCH CORP.Inventors: Cheng-Yu Chen, Ching-Lung Li, Chi Lee
