Abstract: A display driving method and a display device are provided. The display driving method includes following steps: obtaining frame data of a current frame; driving a first pixel according to a first grayscale value corresponding to the first pixel in the frame data; determining whether a second grayscale value corresponding to a second pixel in the frame data is significantly different from the first grayscale value corresponding to the first pixel; obtaining a new second grayscale value when the second grayscale value is significantly different from the first grayscale value; and driving the second pixel according to the new second grayscale value. The display driving method and display device of the disclosure may achieve good display effects.

Abstract: An electronic device includes a display unit, a voltage generation unit, a grayscale adjustment unit, and an overdriving unit. The display unit has a relationship curve between the transmittance and the driving voltage. The relationship curve has a predetermined voltage value corresponding to the maximum transmittance. The voltage generation unit generates a first voltage according to a first grayscale, and generates a second voltage according to a second grayscale. The grayscale adjustment unit receives a first display grayscale value, and outputs the second grayscale value when the first display grayscale value is equal to the first grayscale. The overdriving unit overdrives the second voltage corresponding to the second grayscale to obtain a first target driving voltage, and it provides the first target driving voltage to the display unit.
