  • This abstract for appeared for patent application number 18097948 Titled 'METHOD OF OPERATING DISPLAY DRIVER INTEGRATED CIRCUIT, POWER MANAGEMENT INTEGRATED CIRCUIT AND ELECTRONIC DEVICE INCLUDING THE SAME, AND METHOD OF OPERATING THE SAME'

Simplified Explanation

The abstract describes a method used by a display driver integrated circuit (DDI) to determine if a change in the level of a logic voltage is needed. If a change is required, the DDI sends a command to a power management integrated circuit (PMIC) to adjust the logic voltage level. The DDI then receives a different logic voltage level from the PMIC based on the command sent.


Original Abstract Submitted

An operating method of a display driver integrated circuit (DDI) includes determining whether a change to a level of a first logic voltage supplied to a logic circuit of the DDI is required, based on determining that a change to the level of the first logic voltage is required, transmitting a logic voltage setting command to a power management integrated circuit (PMIC), and receiving, from the PMIC, a second logic voltage having a level different from the first logic voltage and corresponding to the logic voltage setting command.
