Abstract
The present disclosure discloses a driving circuit for electrophoretic display, including a data line driving integrated circuit and a gate line driving integrated circuit, characterized in that the output terminal of each data line in the data line driving integrated circuit is configured with a modulation unit including a thermosensitive element, and the modulation unit adjusts the pulse width of the voltage signal outputted at the output terminal of the data line according to change of temperature to realize temperature compensation for the dielectric characteristic of the electrophoretic film of the electrophoretic display. The present disclosure also discloses an implementation method of the driving circuit and an electrophoretic display device. According to the present disclosure, the workload of the early stage experiment process of the product design can be saved, the production efficiency of the products can be improved, and the storage space of the chip can also be saved.
