Pixel driving device and a light emitting device

A pixel driving device for driving a pixel, connected to a signal line, and comprising a light emitting element, and a drive transistor for controlling the current supplied to the light emitting element by one end of a current path of the drive transistor being connected to one end of the light emitting element, comprising:

• a memory for storing property parameters that relate to the electrical properties of the pixel;
• an image data conversion circuit that converts image data consisting of a digital signal based on a conversion property set in the image data conversion circuit and generates an original gradation signal consisting of a digital signal;
• a signal correction circuit for outputting a corrected gradation signal consisting of a digital signal, by adding the correction amount set based on the value of the property parameter stored in the memory, to the original gradation signal;
• and
• a drive signal impressing circuit for generating a drive signal consisting of an analog signal based on the value of the corrected gradation signal after the corrected gradation signal is input, and impressing the drive signal on one end of the signal line;
• wherein,
• the original gradation signal generated by the image data conversion circuit has a value that corresponds to the gradation value of the image data, and the maximum value of the original gradation signal is set to a value equal to or smaller than a value that is acquired by subtracting a value corresponding to the correction amount in the signal correction circuit from the maximum value in the input range of the drive signal impressing circuit.
