Detailed Description
Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals.
The pixel array applicable to the full-face screen camera area comprises a plurality of composite pixels, wherein each composite pixel comprises two groups of triangular sub-pixels, each group of triangular sub-pixels respectively comprises three primary color sub-pixels with the same shape and area, the two groups of triangular sub-pixels are centrosymmetric and staggered, a first gap is formed between every two adjacent sub-pixels, and a second gap is formed between every two adjacent composite pixels.
Definitions C1, C2 and C3 respectively represent three primary color sub-pixels, the composite pixel is divided into two types, the order of clockwise arrangement around the geometric center of the composite pixel is C1, C2, C3, C1, C2, C3 and C1, C3, C2, C1, C3 and C2, the arrangement mode of the pixel array is: the same composite pixels are arranged in a column, and different composite pixel columns are arranged in a staggered mode.
In the embodiment shown in fig. 1, two groups of triangular sub-pixels are regular triangles, the regular triangles are the best in symmetry and are most easy to generate, but may also be regular triangles with other shapes, and the shape of the sub-pixels can realize various geometric shapes of full light emission, for example, in the OLED light emitting pixel preparation process, the steps of photolithography, cleaning, back electrode plating, packaging, cutting and the like are adopted to realize the production process of integrated circuits, so as to obtain OLED single sub-pixel self-emitting diodes with various shapes.
In each composite pixel, two groups of sub-pixels are symmetrically distributed around the geometric center of the plane of the composite pixel in a staggered manner, as shown in fig. 1, R represents a red sub-pixel, G represents a green sub-pixel, B represents a blue sub-pixel, and sub-pixels of three primary colors of red, green and blue are distributed in a staggered manner to form a composite sub-pixel, and gaps are arranged between the sub-pixels and between the composite pixels and used for ensuring the light transmittance of the front camera area.
In the embodiment shown in fig. 2, two different composite pixels a1 and a2 are arranged: the A1 type composite pixels are arranged in a column, the A2 type composite pixels are arranged in a column, and the column formed by the A1 type composite pixels and the column formed by the A2 type composite pixels are arranged in a staggered mode; and hexagonal composite pixel boundaries are pieced together.
A specific arrangement is shown in more detail in fig. 1, the top of each of the a1 and a2 type composite pixels is a blue sub-pixel B, and six sub-pixels B, G, R, B, G, R and B, R, G, B, R, G are respectively arranged clockwise from the top of the composite pixel according to the hexagonal center, the top pixels are the same, and the remaining two types of sub-pixels are arranged in the clockwise order and in the opposite direction. Although the blue sub-pixel is used as the top in this embodiment, it is known to those skilled in the art that the red or green sub-pixels can be used as the starting point as long as the top pixels of the two types of composite pixels are the same and the arrangement order of the remaining two types of sub-pixels is opposite.
The advantages of such an arrangement are shown in fig. 1, so that in the adjacent areas of two adjacent types of composite pixels, the sub-pixels can be combined to form a composite pixel composed of three different sub-pixels, as indicated by three trapezoids indicated by arrows in fig. 1, each of the three trapezoids represents a composite pixel.
Moreover, the composite pixel itself comprises two groups of RGB sub-pixels, that is, a hexagonal composite pixel can be divided into two trapezoidal RGB sub-pixel groups, and can be used as two complete pixel points during imaging, and the area shapes of the composite pixels formed by the complete pixel points and the adjacent composite pixels are the same, so that the visual distribution of the composite pixels is more integral in imaging.
In the prior art shown in fig. 3, the composite pixel is square, and the red, green and blue sub-pixels are not distributed in a central symmetry manner, so that sub-pixel multiplexing cannot be fully realized at the boundary to increase the number of pixels.
In the area where the front camera is located, the light transmittance is determined by the area not occupied by the pixels, and according to the light transmittance requirement of the area of the front camera, the area of each sub-pixel can be selected, so that for a pixel cell composed of a composite pixel and the peripheral area thereof, the ratio of the area not occupied by the pixels to the total area of the pixel cell meets the light transmittance.
In the prior art shown in fig. 3, each composite pixel comprises 3 kinds of sub-pixels with 8 different sizes, while the composite pixel of the present invention comprises only 2 kinds of sub-pixels with 6 kinds at most, so that the area of a single composite pixel of the present invention is smaller than that of the prior art, which means that more composite pixels can be provided in the same area, and the manufacturing process is simplified compared with the prior art shown in fig. 3.
In the invention, gaps exist among the composite pixels and gaps also exist among the sub-pixels, so that on one hand, the distribution of the light-transmitting gaps can be more uniformly dispersed, the imaging of a camera is facilitated, and meanwhile, the composite pixels formed at the junctions of the composite pixels are more close to the distribution of the sub-pixels in the composite pixels. In the embodiment shown in fig. 1, the colors of the sub-pixels in one composite pixel along the clockwise direction are respectively in staggered distribution of the three primary colors of blue, green, red, blue, green, blue, but may be in other distributions such as blue, red, green, blue, green, and the like, and the distribution is in accordance with the central symmetry.
As shown in fig. 1, the first gap width L1 between the sub-pixels is the average width between two adjacent sub-pixel boundaries around the geometric center of the composite pixel, the distance between two adjacent sub-pixel boundaries is the distance between two boundaries when the two adjacent sub-pixel boundaries are parallel, the distance between two composite pixels, i.e. the second gap width L2, is the average width between two closest sub-pixels between two composite pixels, the distance between two boundaries when the two adjacent sub-pixel boundaries are parallel, and the first gap width L1 and the second gap width L2 can be set to be equal, so that the internal pitch and the external pitch of the composite pixel obtained at the boundary are the same as those of the composite pixel, and the simulation effect is the best.
In the embodiment shown in fig. 1, a preferred technical solution is given, two groups of triangular sub-pixels in a composite pixel have different areas, one group of triangular sub-pixels has a smaller area, and this way has the following advantages compared with the embodiment in which six triangular sub-pixels have the same size:
if the six triangles are equal in size, in order to meet the light transmittance requirement and meet the central symmetry, the distance between the sub-pixels must be smaller, the gap at the center of the formed composite pixel is larger and is obviously larger than the width of the first gap between the sub-pixels, so that the light transmittance of a single composite pixel is uneven and is concentrated at the center and the boundary of the composite pixel, the area between the center and the boundary has small gap and small light transmittance, the density of the camera pixels of the front camera is obviously larger than that of the display screen pixels of the area of the front camera, and the uneven light transmittance of the composite pixels of the single display screen can also influence the imaging quality when the front camera takes a picture. Two groups of sub-pixels with different areas are adopted, the light transmission areas are distributed at the center and the boundary of the composite pixel, more light transmission areas exist between the center and the boundary, and the light transmission areas of the whole composite pixel are more uniform.
According to the invention, through redesigning and arranging the composite pixels, part of sub-pixels can be mutually borrowed between every two adjacent composite pixels, so that the realization of higher resolution with lower pixel number is realized, and the light transmittance of the front camera area is ensured.
The foregoing is a more detailed description of the present invention in connection with specific preferred embodiments thereof, and it is not intended that the specific embodiments of the present invention be limited to these descriptions. For those skilled in the art to which the invention pertains, other embodiments that do not depart from the gist of the invention are intended to be within the scope of the invention.
