Latest Patents

Li-Wei Liu holds a patent for a "Source driving circuit for improving gamma voltage response time and display device." This invention includes a source driving circuit that comprises gamma resistor strings, a digital to analog (DAC) circuit, and an output buffer circuit. The output buffer circuit is designed with an input stage module, gain stage module, and output stage module. The input stage module features both a main input stage unit and an auxiliary input stage unit, where the sizes of elements in the main input stage unit are larger than those in the auxiliary input stage unit. This design minimizes parasitic capacitances, enhancing the circuit's efficiency. During the switching period, the auxiliary input stage unit, gain stage module, and output stage module work together to form a first unity gain amplifier that outputs the driving voltages. In contrast, during the stable period, the main input stage unit, gain stage module, and output stage module create a second unity gain amplifier for the same purpose. This patent represents a significant advancement in display technology.
