Abstract

The invention discloses a display module and a manufacturing method and a driving method thereof, and a display device, and relates to the technical field of display. The display module comprises a first display panel and a second display panel, wherein in a direction perpendicular to a light emitting surface of the first display panel, a first sub-display area and a first display area overlap, asecond sub-display area and the first display area do not overlap; a second sub-pixel in the first sub-display area and a first sub-pixel in the first sub-display area are arranged one by one; the length of the first display area along a first direction is L1, the width of the first display area along a second direction is D1, the length of the second display area along the first direction is L2,and the width of the second display area along the second direction is D2; L1 is less than L2 and greater than 0, and D1 is less than D2 and greater than 0; and in the display phase, the second sub-pixel in the second sub-display area remains normally black displayed or not displayed. The invention solves the problems existing in the double-box liquid crystal display module in the prior art that the image display quality and the process yield are both not high.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display module, a manufacturing method thereof, a driving method thereof and a display device. Background technique [0002] In the TN and SFT display modes of TFT-LCD liquid crystal displays, the contrast ratio is generally between 1000 and 1200:1. Usually, the contrast ratio can be improved by improving pixel optimization design, negative liquid crystal, and optical alignment. After the improvement, it is 1500 to 1800. :1, it is difficult to achieve a contrast level of 5000-10000:1 in VA display mode, and it is even more difficult to achieve a higher contrast ratio. However, based on its display principle, traditional VA LCDs still have relatively large limitations on the display effect and the number of displayed contents. method, but the effect is still not very satisfactory. The dual-cell liquid crystal display can significantly improve the contrast rat...
