Title:
DISPLAY PANEL AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/104846
Kind Code:
A1
Abstract:
A display panel (100), comprising: a liquid crystal panel; a partition optical-rotation box (140) arranged opposite the liquid crystal panel; and a polarizer (150) arranged on one side, facing away from the liquid crystal panel, of the partition optical-rotation box (140), wherein a light transmission axis of the polarizer (150) is perpendicular to or parallel with a light transmission axis of a lower polarizer (130) of the liquid crystal panel; and the partition optical-rotation box (140) is constructed to perform regional rotation on the polarization direction of a light ray penetrating through the polarizer (150), so that the display brightness at different regions of the liquid crystal panel is different. A partition optical-rotation box (140) is inserted into a liquid crystal panel so as to form a display panel (100), and the display brightness at different regions of the display panel (100) during a display process is different, such that the contrast of a displayed image is remarkably improved.
