Abstract
(EN)
Provided are a display panel, and a control method and apparatus therefor, relating to the technical field of display. The display panel comprises a bending region, and the bending region comprises multiple subpixels. The control method comprises: obtaining the attenuation parameter of the subpixel of at least one color of the bending region, wherein the attenuation parameter is the pre-attenuation amount of brightness attenuation of the subpixel; according to the grayscale data of a pixel to which the subpixel of the at least one color belongs, obtaining the pre-register value of the subpixel of the at least one color corresponding to the grayscale data; and according to the pre-register value of the subpixel of the at least one color and the attenuation parameter, adjusting the luminescent brightness of the subpixel of the at least one color. The present invention can alleviate the problem of color shift in the bending region, and improve the display effect of the display panel.

L’invention concerne un panneau d'affichage, et un procédé et un appareil de commande associés, se rapportant au domaine technique de l'affichage. Le panneau d'affichage comprend une région de courbure, et la région de courbure comprend de multiples sous-pixels. Le procédé de commande comprend les étapes consistant à : obtenir le paramètre d'atténuation du sous-pixel d'au moins une couleur de la région de courbure, le paramètre d'atténuation étant la quantité de préatténuation d'atténuation de luminosité du sous-pixel ; en fonction des données d'échelle de gris d'un pixel auquel le sous-pixel de l'au moins une couleur appartient, obtenir la valeur de préregistre du sous-pixel de l'au moins une couleur correspondant aux données d'échelle de gris ; et en fonction de la valeur de préregistre du sous-pixel de l'au moins une couleur et du paramètre d'atténuation, ajuster la luminosité luminescente du sous-pixel de l'au moins une couleur. La présente invention peut pallier le problème de décalage de couleur dans la région de courbure, et améliorer l'effet d'affichage du panneau d'affichage.
