Abstract
A panel display device structure comprises a plurality of pixels and a modulation unit. Each of the pixels comprises a thin film transistor and a light generation device, and the thin film transistor connects to the light generation device. The modulation unit connects to the thin film transistor and makes a signal transformation curve of the pixel to vertically shift in order to adjust the brightness of the pixel by modulating external voltage signal relied on a voltage dividing way or a direct current voltage transfer circuit, so as to satisfy the demand of increasing shifting range of the signal transformation curve.
