Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Because the direction of the electrode strips in the prior art is parallel to or orthogonal to the direction of the minimum width of the corresponding pixel area, the period of the superposed grating is minimum, and the Moire probability that human eyes can distinguish is smaller, so that the display effect of the touch panel is better. However, the touch electrode is arranged to block light emitted by the pixel, thereby affecting the display effect.
Example 1
Fig. 1 is a schematic structural diagram of a pixel layer of the present invention, wherein an area indicated by a dashed line frame is a feature block 1, each feature block 1 includes six pixel blocks 5, each pixel block 5 includes three sub-pixels, the sub-pixels filled by vertical stripes are all red, the sub-pixels filled by grids are all green, and the sub-pixels filled by diagonal stripes are all blue.
As shown in fig. 1, a pixel layer of the present invention includes a plurality of feature blocks 1 arranged repeatedly, each feature block 1 includes a plurality of pixel blocks 5, each pixel block 5 includes at least one sub-pixel, the areas of the pixel blocks 5 are the same or nearly the same, and the shapes of the sub-pixels adjacent to the pixel blocks 5 are different.
The same or nearly the same area of the pixel blocks 5 can ensure that the light emission characteristics of each pixel block 5 are uniform, and in the specific design, since the shapes and the numbers of the sub-pixels of the respective pixel blocks 5 are different, there may be a small difference, i.e., nearly the same, in area between the pixel blocks 5 composed of the sub-pixels, as long as the difference does not greatly affect the uniformity of the light emission characteristics of the pixel blocks 5. The sub-pixels of the adjacent pixel blocks 5 have different shapes, so that two adjacent and same pixel blocks 5 cannot appear in the pixel layer, the regularity of the arrangement of the pixel blocks in the pixel layer is damaged, and the moire phenomenon caused by the similarity of the arrangement of the pixel blocks and the arrangement rule of the metal wires of the electrode layer is avoided. The elimination of the moire fringes by adjusting the arrangement of the pixel layers is simpler than the elimination of the moire fringes by adjusting the arrangement of the electrode layers. Meanwhile, the light emitting characteristics of the pixel blocks 5 are consistent, and a good display effect can be ensured. Specifically, the light-emitting characteristics of the pixel blocks 5 are uniform, and this can be realized by adjusting the areas of the sub-pixels.
Further, it is preferable that the pixel blocks 5 in the feature block 1 are arranged in at least one row, and each row includes at least two pixel blocks 5. In a specific design, the more the number of the pixel blocks 5 arranged in each line is, the more the pixel layers formed by repeatedly arranging a plurality of the feature blocks 1 can avoid the situation that the patterns with similar shapes are closely arranged, and further the moire phenomenon of the pixel layers can be better eliminated.
The line number of the pixel blocks 5 in one feature block 1 and the set number of the pixel blocks 5 in each line are set according to the process requirements, and the actual display effect is optimal. In this embodiment, the feature block 1 preferably includes six pixel blocks 5. Of course, four pixel blocks 5, five pixel blocks 5, seven pixel blocks 5, and the like may be provided.
Further, it is preferable that the six pixel blocks 5 are arranged in two rows, and each row is provided with three pixel blocks. As an alternative embodiment, the six pixel blocks 5 may be arranged in three rows.
The color type and number of the sub-pixels in the pixel block 5 may be set as required, in this embodiment, it is preferable that the pixel block 5 includes three sub-pixels, and the colors of the three sub-pixels are red 2, green 3, and blue 4, respectively. Of course, on the premise of ensuring the display uniformity, the arrangement order of the sub-pixels may be changed according to the actual design requirement, and the sub-pixels in the same pixel block 5 in fig. 1 may also be arranged in the red 2, blue 4, green 3, etc. manner.
As an alternative embodiment, the pixel block 5 comprises four sub-pixels, and the colors of the four sub-pixels are red, green, blue and white, respectively. Of course, the color type of the sub-pixel is not limited thereto.
Further, it is preferable that the pixel blocks 5 have a rectangular shape or an approximately rectangular shape, which facilitates a close arrangement between the pixel blocks 5. Of course, as an alternative embodiment, the pixel block 5 may also be square or approximately square, or triangular, or other shape. As shown in fig. 1, the sub-pixels in the same pixel block 5 may be arranged with gaps or close to each other, and the sub-pixels may be in a random shape such as a triangle, a parallelogram, a cross, a rectangle, an L shape, a D shape, etc., but the sub-pixels in the same pixel block 5 are required to be matched with each other to form a rectangular block or an approximately rectangular block.
Example 2
Fig. 2 is a schematic structural diagram of another pixel layer according to the present invention, in which the region indicated by the dashed line box is the feature block 1, the vertical stripe-filled sub-pixels are all red, the grid-filled sub-pixels are all green, and the diagonal stripe-filled sub-pixels are all blue.
As shown in fig. 2, the pixel layer of the present embodiment includes a plurality of feature blocks 1 arranged repeatedly, each of the feature blocks 1 includes four pixel blocks 5 and is arranged in a row, where the pixel block 5 arranged at the first position and the third position includes three sub-pixels, which are respectively red 2, green 3, and blue 4, and the pixel block 5 arranged at the second position and the fourth position includes only one sub-pixel, which is blue 4.
The three sub-pixels in the pixel block 5 arranged at the first position in the same characteristic block 1 are respectively in the shape of a right triangle, a parallelogram and a right triangle, and the pixel block 5 formed by matching the three sub-pixels is in a rectangular or square shape or an approximate rectangular or approximate square shape. The sub-pixels of the pixel block 5 arranged at the second and fourth positions have the same shape, and are all rectangular or square or approximately rectangular or approximately square. The three subpixels in the third pixel block 5 are respectively in the shape of a right triangle, a parallelogram, or a right triangle, the pixel block 5 formed by the three subpixels in cooperation is rectangular or square or approximately rectangular or approximately square, but the arrangement direction of the three subpixels in the third pixel block 5 is different from the arrangement direction of the three subpixels in the first pixel block 5. The pixels with different colors have different luminous efficiencies, and in order to ensure a good display effect, the luminous efficiency can be improved by increasing the area of a certain sub-pixel, and the luminous efficiency can also be improved by uniformly increasing the arrangement density (arrangement number) of the sub-pixels with a certain color. In this embodiment, the area of the pixel block arranged at the second bit and the area of the pixel block arranged at the fourth bit in the same feature block 1 are increased.
The areas of the pixel block 5 arranged at the first position, the pixel block 5 arranged at the second position, the pixel block 5 arranged at the third position and the pixel block 5 arranged at the fourth position in the same characteristic block 1 are equal or similar, so that the consistency of the light emitting characteristics of each pixel block 5 can be ensured. Because the pixel blocks 5 arranged at the second position and the fourth position in the same feature block 1 only comprise one sub-pixel, and the shape of the sub-pixel is the same, in order to avoid the situation that the shape of the sub-pixels in two adjacent pixel blocks 5 is the same, when arranging, the pixel blocks 5 of the feature blocks 1 in two adjacent rows are arranged along the row arrangement direction in a staggered manner, so that the pixel blocks 5 with the same shape in the feature blocks 1 in two adjacent rows are not adjacent, thereby reducing the generation of moire fringes. The offset arrangement will now be described with the embodiment of fig. 2: the feature blocks in the odd-numbered lines and the feature blocks in the even-numbered lines are arranged in a staggered manner by the position occupied by one pixel block 5, the pixel block with the first feature block in the odd-numbered lines may be positioned in front of the pixel block with the first feature block in the even-numbered lines, or the pixel block with the first feature block in the odd-numbered lines may be positioned behind the pixel block with the first feature block in the even-numbered lines.
As an alternative embodiment of embodiment 2, the number of pixel blocks 5 within the same feature block 1 is not limited to four, and two, three, five, etc. may be provided. The number of sub-pixels comprised by each pixel block 5 within the same feature block 1 may be completely different or partly the same. For example, when four pixel blocks 5 are provided in the same feature block 1, the pixel block 5 arranged at the first position may include three sub-pixels, the pixel block 5 arranged at the second position includes one sub-pixel, the pixel block 5 arranged at the third position includes two sub-pixels, and the pixel block arranged at the fourth position includes four sub-pixels, which is the case where the set number of sub-pixels is completely different.
As an alternative embodiment of embodiment 2, each pixel block 5 in the same feature block 1 may at least comprise two pixel blocks 5 with the same sub-pixel shape, but two pixel blocks 5 with the same sub-pixel shape cannot be adjacently arranged in the same feature block 1. For example, when six pixel blocks 5 are included in the same feature block 1, the shapes of the sub-pixels of the pixel blocks 5 arranged at the second, fourth, and sixth bits may be set to be the same. Of course, the shapes of the sub-pixels arranged in the first, third, and fifth pixel blocks 5 may be the same.
As an alternative embodiment of embodiment 2, the sub-pixels of the pixel block 5 arranged at the first bit and the pixel block 5 arranged at the third bit of the same feature block 1 may be arranged in the order of green, red and blue, or in the order of blue, red and green, or in the order of green, blue and red, etc. The sub-pixels of the pixel block 5 arranged at the second bit and the pixel block 5 arranged at the fourth bit may be set to green or red as necessary. On the premise of ensuring the display uniformity, the arrangement sequence of the pixels can be changed according to the actual design requirements.
As an alternative embodiment of the embodiment 2, the shape of each sub-pixel in the same feature block 1 is not limited to square, triangle, or parallelogram, but may be random as described in the embodiment 1, such as cross, rectangle, L, D, etc., but it is required to ensure that the shapes of sub-pixels in the same pixel block 5 are matched with each other to form a rectangular block, an approximately rectangular block, a square block, or an approximately square block, which is favorable for the close arrangement of the pixel blocks 5.
The display panel comprises the electrode layer and the pixel layer. The display panel provided by the invention has the pixel layer, so that the Moire phenomenon can be well eliminated no matter whether the electrode layer is regularly arranged, and the display effect is improved. Certainly, when the electrode layer is irregularly arranged, the effect of eliminating the moire is better.
Further, the electrode layer is a metal grid, and projections of metal wires of the metal grid on the pixel layer are arranged corresponding to gaps between the sub-pixels. Therefore, the metal wires in the metal grids can be prevented from blocking the light emission of the sub-pixels, and the display effect is improved. Of course, the projection of the metal wires of the metal mesh on the pixel layer may not be set corresponding to the gaps between the sub-pixels, or may be partially set corresponding to the gaps between the sub-pixels, such a setting may also eliminate moire, but may block a part of light, which affects the display effect.
The display device provided by the invention is provided with the display panel, so that the Moire can be well eliminated, and the display effect is good. The display device can be an electronic device with a display panel, such as a mobile phone, a computer, a digital camera, and the like.

Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
