Abstract

The invention provides a pixel driving device, a light emitting device, a driving / controlling method thereof, and an electric device. in a pixel driving device that drives a plurality of pixels, each pixel includes a light emitting element and a pixel driving circuit comprising a driving device having one end of a current path connected to one end of the light emitting element and having another end of the current path to which a power-source voltage is applied. provided in a controller is a correction-data obtaining function circuit which obtains a first characteristic parameter relating to a threshold voltage of the driving device of each pixel based on a voltage value of each data line after a first detection voltage is applied to each data line connected to each pixel, and a current is caused to flow through the current path of the driving device through the each data line with a voltage of another end of the light emitting element being set to be a first setting voltage. the first voltage is set to be equal to the first detection voltage or to be lower than the first detection voltage and the potential difference with the first detection voltage is smaller than the voltage of the threshold voltage of the light emitting element.

Description

[0001] This application claims the specification, claims, drawings, and abstract based on the Japanese patent application No. 2009-298219 filed on December 28, 2009 and the Japanese patent application No. 2010-256738 filed on November 17, 2010. priority. The disclosure of this patent application is incorporated in this application as a whole as a reference. technical field [0002] The present invention relates to a pixel driving device, a light emitting device having the pixel driving device, a driving control method thereof, and an electronic device having the light emitting device. Background technique [0003] In recent years, as a next-generation display device, a light-emitting element-type display device (light-emitting device) having a display panel (pixel array) in which current-driven light-emitting elements are arranged in a matrix has attracted attention. Among them, known examples of current-driven light-emitting elements include organic electroluminescent elem...
