Abstract:
A display device includes a display panel having data lines, gate lines and a plurality of subpixels. Each of the plurality of subpixels are defined by the data lines and the gate lines, and each of the plurality of subpixels includes a circuit having a transistor. A plurality of Digital Integrated Circuits (DICs) where a digital to analog converter (DAC) is disposed within each of the plurality of DICs. An analog to digital converter (ADC) is disposed within each of the plurality of DICS, where the ADC disposed in each of the plurality of DICs includes a plurality of sensing channels. The display device includes a pixel compensation circuit to compensate a characteristic of the transistor within each of the plurality of subpixels and an ADC compensation circuit to compensate a characteristic of the ADC within each of the plurality of DICs.
