The display panel provided by the present disclosure is described in detail below with reference to specific embodiments.
First embodiment
Fig. 1 illustrates a top view of a display panel provided by a first embodiment of the present disclosure, fig. 2 illustrates an optical path diagram of the display panel provided by the first embodiment of the present disclosure, fig. 3 illustrates a cross-sectional view of the display panel of the first embodiment of the present disclosure along a P-P direction, and fig. 4 illustrates an effect diagram of the display panel provided by the first embodiment of the present disclosure in the non-display area NA electrical connection.
Referring to fig. 1 to 4, the embodiment of the present disclosure provides a display panel, which includes an array substrate 100, a first color film substrate 200, and a second color film substrate 300. A first liquid crystal layer (not shown) is formed between the array substrate 100 and the first color film substrate 200, and a second liquid crystal layer (not shown) is formed between the first color film substrate 200 and the second color film substrate 300. The first liquid crystal layer and the second liquid crystal layer each comprise a plurality of liquid crystal molecules, which are typically rod-shaped, and which both flow like a liquid and have certain crystal characteristics. When the liquid crystal molecules are in an electric field, the alignment direction thereof is changed according to the change of the electric field.
The first color film substrate 200 includes a first color resist layer 210 facing the array substrate 100, wherein the first color resist layer includes a plurality of first color resist units distributed in an array;
The second color film substrate 300 is disposed on a side of the first color film substrate 200 facing away from the array substrate 100, the second color film substrate 300 includes a second color resist layer 310 facing the first color film substrate 200, the second color resist layer 310 includes a plurality of second color resist units distributed in an array, and the orthographic projection of the first color resist unit on the array substrate 100 overlaps with the orthographic projection of the second color resist unit of the same color on the array substrate 100.
In this embodiment, in order to improve the display effect of the display panel, the display panel is configured as a combined member including at least the array substrate 100, the first color film substrate 200 and the second color film substrate 300. Specifically, the first color film substrate 200 is disposed on the array substrate 100, the second color film substrate 300 is disposed on the first color film substrate 200, and the second color film substrate 300 and the array substrate 100 are respectively located at two opposite sides of the first color film substrate 200. The first color film substrate 200 is coated with a first color resist layer 210, the first color resist layer 210 comprises at least one group of RGB color blocks, each group of RGB color blocks comprises at least three first color resist units, the second color film substrate 300 is coated with a second color resist layer 310, the second color resist layer 310 comprises at least one group of RGB color blocks, and each group of RGB color blocks comprises at least three second color resist units. The RGB color blocks of the first color resist layer 210 and the RGB color blocks of the second color resist layer 310 are partially overlapped in a staggered manner, that is, the first color resist units in the corresponding RGB color blocks of the first color resist layer are partially overlapped with the second color resist units of the same color in the RGB color blocks of the second color resist layer.
Further, the first color resist layer 210 is used for generating a virtual image, and the second color resist layer 310 is used for locally brightening the virtual image generated by the first color resist layer 210, so that the image shown by the display panel has a chromaticity difference, and when the image enters eyes of a user, a display effect of a three-dimensional image is generated. Specifically, the chromaticity of the image displayed at the overlapping portion of the second color resist layer 310 and the first color resist layer 210 is strong, and the chromaticity of the image displayed at the non-overlapping portion of the second color resist layer 310 and the first color resist layer 210 is weak, so that the image imaged by the first color resist layer 210 and the second color resist layer 310 has obvious chromaticity difference, and along with the position change of the user, the light path passing through the second color film substrate 300 deflects and refracts to generate a view without a visual angle, thereby realizing the three-dimensional display effect.
In addition, the display panel provided by the embodiment of the disclosure does not adopt the grating structure or the lenticular lens and other light-splitting devices in the traditional display panel to realize the three-dimensional display effect, so that the use of the light-splitting devices is avoided, the thickness of the display module is effectively reduced, the display function of the display panel is improved, and the production cost is greatly reduced.
For example, but not limited to, the array substrate 100 is a TFT glass substrate.
In one possible implementation, the area of the overlapping portion between the front projection of the first color resist unit on the array substrate 100 and the front projection of the second color resist unit on the array substrate 100 is A1, and the sum of the front projection area of the first color resist unit on the array substrate 100 and the front projection area of the second color resist unit on the array substrate 100 is A2, so that a1/a2=1/2 to 1/3.
In this embodiment, the overlapping degree of the second color resist layer 310 and the first color resist layer 210 is optimally set. Specifically, the first color resist layer 210 and the second color resist layer 310 are offset to overlap by 1/2 to 1/3 of a unit area. It can also be said that the width of a single color resistance unit of the RGB color blocks of the first color resistance layer 210 is X, and the distance between two adjacent color resistance units in the group of RGB color blocks is 1/2X-1/3X, that is, the distance between R pixel and G pixel is 1/2X-1/3X, and the distance between G pixel and B pixel is 1/2X-1/3X. When the second color film substrate 300 is assembled on the first color film substrate 200, the RGB color blocks of the second color film substrate 300 are dislocated from the RGB color blocks of the first color film substrate 200, and the portion of the R pixel of the second color film substrate 300 is correspondingly disposed above the corresponding position of the R pixel and the G pixel of the first color film substrate 200. That is, in the width direction of the color resistance unit, the front projection of the R pixel of the second color film substrate 300 and the front projection of the R pixel of the first color film substrate 200 have 1/2 to 2/3 of the non-overlapping portion, the chromaticity of the image displayed on the non-overlapping portion is weak, and the chromaticity of the image displayed on the overlapping portion is strong and the intensity is alternating, so that the image displayed on the display panel has a stereoscopic impression, which is beneficial to strengthening the display effect of the display panel.
In one possible implementation manner, the shapes of the first color resistance unit and the second color resistance unit are rectangular, the orthographic projection of the first color resistance unit on the array substrate 100 and the orthographic projection of the second color resistance unit with the same color on the array substrate 100 are partially overlapped along a preset direction, and the value range of an included angle B between the preset direction and the width direction of the first color resistance unit is 0.ltoreq.B.ltoreq.90 degrees.
In this embodiment, the shapes of the first color resist unit and the second color resist unit are optimized, and the specific overlapping portions of the first color resist unit and the second color resist unit are optimized. Specifically, the first color resist unit and the second color resist unit are each provided in a rectangular shape. The rectangular color resistance units can be overlapped in the transverse direction (0 degrees), can be overlapped in the longitudinal direction (90 degrees), and can be overlapped in the oblique direction (30 degrees, 45 degrees or 60 degrees and the like), namely, the value range of an included angle B between the overlapping direction and the width direction of the first color resistance unit is 0-90 degrees. Preferably, the rectangular color resist units overlap in the lateral direction to obtain a more excellent display effect.
In one possible embodiment, the first color film substrate 200 further includes a first substrate 220, and the first color resist layer 210 is disposed on the first substrate 220;
The second color film substrate 300 further includes a second substrate 320, and the second color resist layer 310 is located on the second substrate 320;
The positions of the first color resist units on the first substrate 220 and the positions of the second color resist units on the second substrate 320 are aligned along a predetermined direction, and the first substrate 220 and the second substrate 320 are arranged in a staggered manner along the predetermined direction.
In this embodiment, the relative positions of the first color film substrate 200 and the second color film substrate 300 are specifically set.
