Abstract: The present disclosure provides a voltage compensation device, a method for voltage compensation and a display device. The voltage compensation device comprises a plurality of thermosensitive sensors, a processor and a power source management module. Each thermosensitive sensor corresponds to one or more pixel units of a display device and is disposed at a position corresponding to the one or more pixel units. For each thermosensitive sensor and one or more pixel units that corresponds to the thermosensitive sensor, the processor is configured to: determine an actual pixel voltage of the one or more pixel units; determine a compensated data signal; transmit the compensated data signal to the power source management module; and control the power source management module to output a compensated data voltage to the one or more pixel units, enabling the one or more pixel units to reach or approach the reference pixel voltage.
