Problems solved by technology
[0005] It can be seen that due to the deviation and misalignment of the main cell and sub cell, the direct impact is that the display of the main cell and sub cell will appear misaligned, which will not only lead to blurred edges, ghosting, smearing, or aliasing in the final image The feeling is serious, and the original mura will increase, which will affect the user experience

The invention discloses a dual cell display panel, a manufacturing method and a driving method thereof, and a display device; the dual cell display panel comprises a main cell and a sub cell which are arranged in a stacked manner, and an XPCBA board which is located at one side, far away from the main cell, of the sub cell and stores offset pixel quantity and mura compensation data; the offset pixel quantity is the quantity of pixel dislocation between a first display area of the main cell and a second display area of the sub cell after the main cell and the sub cell are attached, and the mura compensation data is data for compensating mura in the main cell and the sub cell; a control panel is used for reading offset pixel quantity and mura compensation data from the XPCBA board, and adjusting at least one of the first display area and the second display area according to the offset pixel quantity, so that pixels orthographically projected in an actual display area of the dual cell display panel in the first display area and the second display area are subjected to picture display; finally, the mura data in the main cell and the sub cell is compensated according to the mura compensation data.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a stacked display panel, a manufacturing method, a driving method, and a display device. Background technique [0002] Due to equipment manufacturing capabilities, large-scale display panel (panel) products often have large areas of uneven brightness and darkness (mura). The dividing line is 1 to 2 pixels wide in the vertical or horizontal direction, and there is brightness on both sides. Difference. [0003] Since the stacked screen (BOE Dual Cell, BD Cell) adopts a double-layer LCD screen design (that is, two screens, the main cell and the sub cell, are overlapped together), it can be made larger than the organic light-emitting diode (Organic Light-Emitting Diode, OLED) screen. size, and its display effect is comparable to that of OLED displays, so it is widely used in large-size screens. [0004] However, in the prior art, the lamination accuracy of the main cell an...
