Specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
In a first aspect of the invention, a method for processing a small-pitch spherical display screen module is provided. As shown in fig. 1, a method for controlling dynamic partitioning of a liquid crystal backlight according to an embodiment of the present invention may be summarized as including steps S100 to S300:
step S100: acquiring hypotenuse information of the right trapezoid module;
step S200: acquiring the plurality of complete pixel distribution information, wherein the distribution information comprises edge pixel distribution information positioned near the oblique edge;
step S300: and judging the position relation between a complete pixel and the trapezoid hypotenuse based on the hypotenuse information and the distribution information, and rearranging the edge pixels based on the position relation so as to uniformly arrange rearranged pixel points.
Fig. 2 a-2 c show the configuration of the spherical display screen according to the present invention. Fig. 2a shows a schematic view of a spherical display screen according to an embodiment of the present invention, fig. 2b shows a display module according to an embodiment of the present invention, and fig. 2c shows a complete pixel point according to an embodiment of the present invention. As shown in fig. 2 a-2 b, the sphere of the invention is formed by splicing a plurality of rectangular and trapezoidal modules with different sizes, each row of the box body is shown in the figure, the rectangular modules are aligned from the middle to the two ends, the rectangular modules are symmetrically distributed and arranged along the sphere from the high to the low, and two right trapezoid modules are symmetrically distributed at the two ends of the row. As shown in fig. 2c, the pixel arrangement of the present invention uses four times of pixel multiplication technology as a reference, and one pixel unit includes four light emitting points of R/G/B.
Under the condition of splicing the rectangle and the trapezoid, the number of the required lamp points in each row is inconsistent as the sizes of the upper bottom edge and the lower bottom edge of the trapezoid are different and calculated according to the standard point spacing. Therefore, the edge light points need to be added or subtracted appropriately according to the actual situation, and rearranged, so as to ensure that the human eyes cannot distinguish the uncomfortable feeling caused by the gaps generated by splicing and inconsistent pitches of the light points in the process of watching images or videos.
Therefore, the invention realizes seamless splicing by processing the pixel points at the edge of the module, and meets the visual requirement of spherical screen display. The following processes are performed differently with respect to the positional relationship between the edge pixels and the right trapezoid hypotenuse.
In one embodiment of the present invention, as shown in fig. 3, a first pixel rearrangement diagram according to an embodiment of the present invention is shown. In this case, if a complete pixel is outside the trapezoid bevel, the pixel needs to be deleted. In fig. 3, 6 small rectangular frames on the right side show 6 complete pixel units, and the complete pixel units are all arranged outside the right trapezoid oblique sides, so in this embodiment, in order to ensure that the human eyes cannot distinguish uncomfortable feeling caused by gaps generated by splicing and inconsistent lamp point pitches in the process of watching images or videos, the 6 complete pixel units are deleted.
In one embodiment of the present invention, as shown in fig. 4, a second pixel rearrangement diagram according to an embodiment of the present invention is shown. In this case, the pixel pitch is assumed to be n, and the distance between the center of the edge light point and the hypotenuse edge should be n/2. If the center distance between the edge pixel and the hypotenuse is greater than half of the distance between the two complete pixels, the edge pixel is moved towards the hypotenuse; if the distance between the center of the edge pixel and the hypotenuse is smaller than half of the distance between the two complete pixels, the edge pixel is moved to a direction far away from the hypotenuse; in fig. 4, two adjacent small squares represent one R/G/B light emitting point, the distance between any two light emitting points is n, and the pitch of the complete pixel is also n. When comparing the position relation of the right trapezoid hypotenuse and the complete pixel, the center distance of the edge lamp points of the complete pixel is used, as marked by an oval frame in the figure. In the left graph, the distance between the center of the edge lamp point and the edge of the bevel edge is larger than n/2, so that the left lamp point needs to be moved outwards; in the right view of fig. 4, the center of the edge light point is less than n/2 from the bevel edge, and the left light point is required to move inward.
In an embodiment of the present invention, as shown in fig. 5, a third pixel rearrangement diagram according to an embodiment of the present invention is shown. In this case, the right trapezoid hypotenuse is between one complete pixel cell. As shown in the left diagram of fig. 5, a complete pixel unit is located in the circular area, the oblique side is located at the right side of the center of the pixel unit, at this time, the whole pixel unit is moved to the left until the whole pixel unit is located in the range of the oblique side, and the light-colored unit is located at the moved position. As shown in the right graph of fig. 5, a complete pixel unit is located in the circular area, and the oblique side is located at the left side of the center of the pixel unit, at this time, if the center of the edge pixel falls outside the right trapezoid, the edge pixel is deleted, and the complete pixel adjacent to the edge pixel and located at the inner side is moved toward the direction close to the oblique side, so that the distance between the moved complete pixel center and the oblique side is half of the distance between two complete pixels. In the right diagram of fig. 5, a complete pixel unit is arranged in the square area, the hypotenuse is arranged at the left side of the center of the pixel unit, the pixel unit is deleted, and the pixel unit in the round area adjacent to the left side is moved to the right, so that the distance between the center of the edge lamp point and the edge of the hypotenuse is n/2, and the light-colored unit is the moved position.
In a preferred embodiment of the present invention, as shown in fig. 6, a schematic diagram of pixel sharing according to an embodiment of the present invention is shown. For the three pixel rearrangement cases, after the pixel units move, the row of pixel units and the adjacent m rows of pixel units are transversely equally divided, so that the transverse interval consistency of the m+1 rows of pixels at the edge is ensured, and the problem of display image distortion caused by inconsistent intervals can be reduced by adopting the processing method.
It should be noted that the pixel shifting and the averaging operation should satisfy the following points:
1. the pixel spacing difference of each row needs to be controlled within n/10 so as to ensure that the human eyes cannot recognize the pixel difference after the spherical screen correction;
2. after the pixel points are moved, m rows of pixels are equally divided, and m is required to be as small as possible so as to ensure the production speed;
3. after the pixel points are added at the edge position of the lamp panel, the pixel density is increased, and the small-size light-emitting tube core can be used for replacing the original tube core;
4. after the pixel points are reduced at the edge positions of the lamp panel, the pixel density is reduced, and the large-size light emitting tube core can be used for replacing the original tube core.
Based on the small-space spherical display screen module processing method described in fig. 1-6, the second aspect of the invention also provides a display device; the method is manufactured by the small-space spherical display screen module processing method.
While various embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous modifications, changes, and substitutions will occur to those skilled in the art without departing from the spirit and scope of the invention.
