Latest Patents

Zhong holds a patent for a "Low current voltage supply circuit for an LCD driver." This invention employs two voltage dividers to optimize the bias voltage supplied to the LCD. The low current voltage divider utilizes resistive elements with high resistance to provide a bias voltage with minimal current. In contrast, the high current voltage divider employs low resistance elements to deliver a high current bias voltage during critical time phases. This dual approach allows for rapid updates to the bias voltage levels, resulting in a fast settling time for the liquid crystal display. Additionally, the circuit features a halt mode that disconnects both voltage dividers from the voltage source during sleep mode, effectively reducing power consumption.
