Display panel luminance calibration method, and display panel luminance calibration device

摘要

The present application provides a method for calibrating luminance of a display panel and an apparatus for calibrating luminance of a display panel. The display panel includes a transparent display area and a non-transparent display area, the transparent display area is a double-sided light-emitting display area, a front surface of the transparent display area is a surface closer to ambient light, and a rear surface is a surface away from ambient light, The luminance calibration method includes: starting a luminance calibration flow based on a luminance calibration start command; Under the current state, a first curve representing the relationship between the absolute value of the input voltage of the transparent display area and the emission luminance value of the transparent display area is obtained, and the first curve is used as the absolute value of the input voltage for luminance correction and the transparent display area. Recording as a relationship curve of the emission luminance values of; And adjusting the input voltage of the transparent display area based on the first curve so that the front emission luminance value of the transparent display area coincides with the emission luminance value of the non-transparent display area, or the front emission luminance of the transparent display area. Restoring the value to a factory setting luminance value; Includes.
