Title
(EN) Chromaticity adjusting method, chromaticity adjusting device and display panel
(ZH) 一种色度调节方法、色度调节装置及显示面板
Abstract
(EN) The invention provides a chromaticity adjusting method, a chromaticity adjusting device and a display panel. The chromaticity adjusting method comprises the following steps: acquiring chromaticity ofa white picture of a display panel; determining whether the chromaticity under the white picture deviates from a target value or not; if the chromaticity under the white picture deviates from the target value, adjusting the thickness of the blue liquid crystal layer; and adjusting the thickness of the blue liquid crystal layer to enable the chromaticity under the white picture to accord with a target value. In addition, after the thickness of the blue light resistance layer is adjusted, the adjustment amplitude of the gray scale of the blue sub-pixel (B) can be reduced, the influence on the light transmittance is reduced while the chromaticity is improved, and color crosstalk is avoided.
(ZH) 本发明提供一种色度调节方法、色度调节装置及显示面板。该色度调节方法包括:获取显示面板白画面下的色度。确定所述白画面下的色度是否偏离目标值。若所述白画面下的色度偏离所述目标值,则调节蓝色液晶层的厚度。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。从而改善显示面板显示色度出现偏差的情况,并且,调节蓝色光阻层厚度后,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。
