Title:
CONTROL DEVICE, DISPLAY DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/203660
Kind Code:
A1
Abstract:
This control device comprises a monitor control unit for obtaining, from within a sweep range, a measured value relating to a characteristic of a pixel circuit provided with a light emitting element and a drive transistor for controlling a current flowing to the light emitting element, a correction parameter determining unit for determining a correction parameter on the basis of the measured value, and a signal correction processing unit for correcting a gradation value on the basis of the correction parameter and calculating a drive voltage value of the pixel circuit, wherein the monitor control unit determines the sweep range on the basis of a reference measured value, which is the measured value obtained in the past.
