Abstract

In a pixel driving device that drives a plurality of pixels, each of the plurality of pixels 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 that obtains a characteristic parameter including a threshold voltage of the driving device of each pixel based on a voltage value of each of a plurality of data lines connected to each of the plurality of pixels with a voltage of another end of the light emitting element being set to be a setting voltage. The setting voltage is a voltage set based on a voltage value of each data line at a predetermined timing.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2009-298555 filed on December 28, 2009, including specification, claims, drawings and abstract. The disclosure of this patent application is incorporated by reference in its entirety in this application. 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 elements (organic EL elements), inorganic electroluminescent elements (inorganic...
