Display device and method of driving the same, and electronic device including the display device

Abstract

A display device includes: a display panel including pixels each having a light emitting element located between a first power source receiving a first power voltage and a second power line receiving a second power voltage, and photo sensors including a light receiving element located between a third power line receiving a reset voltage and the second power line; at least one temperature sensor for sensing a temperature of the display panel; a power supply for supplying the first power voltage, the second power voltage, and the reset voltage; and a controller connected to the temperature sensor and the power supply. The controller controls the power supply such that a voltage value of the reset voltage is changed based on the temperature of the display panel.
