LIGHT EMITTING DEVICE DRIVING CIRCUIT, DISPLAY, AND A/D CONVERSION CIRCUIT |
摘要 |
A light emitting device driving circuit according to the present disclosure includes a sawtooth waveform generating unit for generating a sawtooth waveform voltage having a sawtooth waveform voltage change based on at least two reference signals to be input and a comparison unit for comparing an analog signal voltage with the sawtooth waveform voltage. The light emitting device driving circuit drives a light emitting device based on the comparison result of the comparison unit. Accordingly, a comparison operation using a sawtooth waveform voltage having a waveform which is not disturbed is performed. |
