Abstract
(EN) A chrominance adjustment method and device, and a display panel. According to the chrominance adjustment method, the thickness of a blue liquid crystal layer is adjusted to enable chrominance of a white image to satisfy a target value, thereby mitigating the situation that deviation occurs in the display chrominance of a display panel (30); moreover, after the thickness of a blue photoresist layer (3031) is adjusted, the adjustment amplitude of the gray scale of a blue sub-pixel (B) can be reduced, the effect on light transmittance is reduced while the chrominance is improved, and color crosstalk is avoided.
(FR) La présente invention concerne un procédé et un dispositif de réglage de chrominance et un panneau d'affichage. Selon le procédé de réglage de chrominance, l'épaisseur d'une couche de cristaux liquides bleus est ajustée pour permettre à la chrominance d'une image blanche de satisfaire une valeur cible, ce qui permet d'atténuer la situation dans laquelle un écart se produit dans la chrominance d'affichage d'un panneau d'affichage (30); de plus, après ajustement de l'épaisseur d'une couche de résine photosensible bleue (3031), l'amplitude de réglage de l'échelle de gris d'un sous-pixel bleu (B) peut être réduite, l'effet sur la transmittance de lumière est réduit tandis que la chrominance est améliorée et la diaphonie de couleur est évitée.
(ZH) 一种色度调节方法、色度调节装置及显示面板,其中色度调节方法是通过调节蓝色液晶层的厚度以使得白色画面下的色度符合目标值,从而改善显示面板(30)的显示色度出现偏差的情况,并且,调节蓝色光阻层(3031)的厚度后,能够缩小蓝色子像素(B)灰阶的调整幅度,在改善色度的同时,减小对光线穿透率的影响,避免颜色串扰。
