Embodiment Construction
[0035] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0036] The terminology used in the present invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein and in the appended claims, the singular forms "a", "the", and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It should also be understood that the term "and / or" as use...

The invention discloses a color film substrate, a preparation method of the color film substrate, a display panel and a display device. The color film substrate comprises a substrate, and a black matrix which is formed on the substrate; the black matrix comprises latticed shading strips; openings of a plurality of sub-pixels are defined by the latticed shading strips, and the plurality of sub-pixels comprise color sub-pixels and white sub-pixels; the color film substrate further comprises a plurality of color resistance blocks; the orthographic projection of each color resistance block on theplane where the color film substrate is located completely covers an opening of one color sub-pixel; the orthographic projection of the color resistance block of at least one color sub-pixel adjacentto the white sub-pixel on the plane where the color film substrate is located also covers one part of the opening of the white sub-pixel; therefore, the difference value between the whiteness of the display picture and the whiteness of the display picture in the high color gamut mode (not starting the white sub-pixels) is reduced, and small visual difference is brought to a user.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] With the development of electronic products, screens are more and more widely used in people's lives. With the improvement of screen resolution, in order to increase the display brightness of the screen, the liquid crystal display panel in the screen usually adopts the RGWB four-color display technology. [0003] At present, only the red color resistance corresponding to the red sub-pixel R, the green color resistance corresponding to the green sub-pixel G, the blue color resistance corresponding to the blue sub-pixel B, and the corresponding white sub-pixel are set on the color filter of the display panel. W is filled with a planarization layer (OC), and the transmittance of the planarization layer is usually close to 100%. [0004] In practical appl...
