Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The inventors found in the intensive studies that: a general display panel needs to be provided with a support column to ensure the strength and pressure resistance of the display panel. The supporting posts absorb part of large-angle light rays emitted from the sub-pixels arranged on the peripheral sides of the supporting posts, so that the supporting posts can be seen from the sideThe shielding of the sub-pixel light is realized. The large-angle light rays emitted by the sub-pixels are emitted from the sub-pixels, an included angle theta is formed between the large-angle light rays and the long axis of the support column in the thickness direction of the display panel, and the value range of the theta is 0-90 degrees (the end point values are not 0 degree and 90 degrees). In the display process of the display panel, the white balance of the front view direction of the display panel can be adjusted by the driving chip to achieve the required white balance, but the side view direction of the display panel cannot be adjusted by the method. Fig. 1 is a schematic top view of a display panel according to an embodiment of the present application. In some examples, a substrate, a driving substrate, a light emitting device layer, and a cover plate are stacked in a thickness direction of the display panel. The light emitting device layer includes a pixel defining layer including a plurality of pixel openings arranged in an array. The sub-pixels are correspondingly arranged in the pixel openings. The supporting columns are arranged on one side of the pixel limiting layer, which faces away from the driving substrate, and are used for absorbing and shielding part of large-angle light rays emitted from the sub-pixels on the peripheral side of the supporting columns. As shown in fig. 1, the display panel 1 includes a first direction and a second direction, the first direction and the second direction intersect to form a first plane, and fig. 1 is a top view of the display panel, the first plane is perpendicular to the thickness direction of the display panel. The first direction comprises a left side viewing direction X which is positioned at the same horizontal line and is opposite to the first direction2And right side view direction X1. The second direction comprises a front side view direction Y which is at the same horizontal line and opposite to the first direction2And a rear side view direction Y1。
Display panel has the multiple subpixel that is the different colours that the array was arranged, and the inventor discovers because general support column sets up the mode for the support column shelters from the mode inconsistent to display panel different colours subpixel in different side directions, thereby the different visual angle colour that look side the direction is inclined to the left track uniformity relatively poor, and display panel is different to look side the direction and is colored partially the colour inconsistent, influences display panel's colour rendering display effect and user experience.
As shown in fig. 2, the following is an exemplary test method of the viewing angle color cast trajectory of any one side view direction of the display panel 1:
the image information collector 2 is arranged to be seen from any side of the display panel 1 from the right above direction (as shown in fig. 2 by way of example)To left side looking at direction X2) And in the process of moving along the Z track, obtaining the image information of the plurality of test points under different observation angles, thereby obtaining the color coordinate values of the display surface under different observation angles in the side view direction. Connecting the color coordinate values of the display surfaces at different observation angles and under the same side-viewing direction to obtain a viewing angle color cast track in the side-viewing direction. Close to X in FIG. 22The direction indicated by the arrow is the direction in which the user views the display panel from a side view angle, and may be referred to as a side view direction.
As shown in fig. 3, the support pillars in the general display panel are distributed so that the difference between the color cast trajectories of the viewing angles obtained in different side viewing directions is large, and the coincidence degree is low, so that the display panel has different color cast colors in different side viewing directions, and the display effect of the display panel is affected. In FIG. 3, CIE-Y-0 represents the color shift locus of the viewing angle in the left side viewing direction, CIE-Y-90 represents the color shift locus of the viewing angle in the front side viewing direction, CIE-Y-180 represents the color shift locus of the viewing angle in the right side viewing direction, and CIE-Y-270 represents the color shift locus of the viewing angle in the rear side viewing direction. The color cast of the display panel in different side viewing directions is different, for example, when a user views the display panel in a left side viewing direction, the display surface is blue, and when viewing the display panel in a right side viewing direction, the display surface is green.
