Abstract
(EN)
A display panel luminance correction method and a display panel luminance correction device. The display panel comprises a transparent display area (10) and a non-transparent display area (11), the transparent display area (10) being a double-sided light-emitting display area, and the front face of the transparent display area (10) being a side close to ambient light, and the back side thereof being a side away from the ambient light. The luminance correction method comprises: starting a luminance correction procedure according to a luminance correction start instruction (S11); acquiring a first curve in the current state representing the relationship between the absolute value of the input voltage of the transparent display area (10) and the luminance value of the transparent display area (10), and recording the first curve as a relation curve, used for luminance correction, between the absolute value of the input voltage and the luminance value of the transparent display area (10) (S12); and adjusting the input voltage of the transparent display area (10) according to the first curve, enabling the front luminance value of the transparent display area (10) to be consistent with the luminance value of the non-transparent display area (11), or enabling the front luminance value of the transparent display area (10) to be restored to a factory set luminance value (S13).

L'invention concerne un procédé de correction de luminance de panneau d'affichage et un dispositif de correction de luminance de panneau d'affichage. Le panneau d'affichage comprend une zone d'affichage transparente (10) et une zone d'affichage non transparente (11), la zone d'affichage transparente (10) étant une zone d'affichage électroluminescente à double face, et la face avant de la zone d'affichage transparente (10) étant un côté proche de la lumière ambiante, et le côté arrière de celle-ci étant un côté à l'opposé de la lumière ambiante. Le procédé de correction de luminance consiste à : démarrer une procédure de correction de luminance selon une instruction de début de correction de luminance (S11) ; acquérir une première courbe dans l'état actuel représentant la relation entre la valeur absolue de la tension d'entrée de la zone d'affichage transparente (10) et la valeur de luminance de la zone d'affichage transparente (10), et enregistrer la première courbe en tant que courbe de relation, utilisée pour la correction de luminance, entre la valeur absolue de la tension d'entrée et la valeur de luminance de la zone d'affichage transparente (10) (S12) ; et ajuster la tension d'entrée de la zone d'affichage transparente (10) selon la première courbe, permettant à la valeur de luminance avant de la zone d'affichage transparente (10) d’être cohérente avec la valeur de luminance de la zone d'affichage non transparente (11), ou permettant à la valeur de luminance avant de la zone d'affichage transparente (10) d'être rétablie à une valeur de luminance réglée en usine (S13).
