DATA DRIVING CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME: abstract simplified (18210960)

• This abstract for appeared for patent application number 18210960 Titled 'DATA DRIVING CIRCUIT AND DISPLAY DEVICE INCLUDING THE SAME'

Simplified Explanation

The abstract describes a circuit that uses a series of resistors and data channels to convert digital data signals into analog voltages. The circuit includes a resistor string with multiple resistors connected in series. The data channels are connected to different voltage nodes of the resistor string and are designed to convert the digital data signal into an analog voltage. Each data channel consists of a main digital-to-analog converter connected to the high, intermediate, and low voltage nodes, a multiplier connected to the output of the main converter, a sub digital-to-analog converter connected to some of the voltage nodes, and a voltage synthesizer connected to the output of the multiplier and the sub converter.
