DETAILED DESCRIPTION

For clearer descriptions of the objectives, technical solutions, and advantages of the present disclosure, embodiments of the present disclosure are described in detail hereinafter with reference to the accompanying drawings.

Single-slit diffraction is a phenomenon that light waves bypass an obstacle and continue to propagate when light encounters the obstacle during propagation. As shown in FIG. 1, in the single-slit diffraction, the smaller the absolute value of a diffraction order k is, the greater the light intensity I is; and the larger the absolute value of the diffraction order k is, the less the light intensity I is, where k is an integer. Light interference is a phenomenon that two or more columns of light overlap each other when meeting in space, and the light is always intensified in some regions e1 and always weakened in other regions e2, thereby forming a stable intensity-weakness distribution, as shown in FIG. 2.

FIG. 3 is a schematic structural diagram of a grating according to some embodiments of the present disclosure. Referring to FIG. 3, the grating is an optical element including a plurality of parallel slits with an equal width and equal interval. In FIG. 3, the width of a light-transmitting region (the light-transmitting region is also called a slit) is a, the width of an opaque region is b, and the sum of the width of the light-transmitting region and the width of the opaque region is called a length d of one period of the grating, that is, d=a+b.

The light intensity curve of multi-slit interference is shown in FIG. 4, and the light intensity of multi-slit interference satisfies:

$\begin{array}{cc}I={I_0\left(\frac{\sin \alpha }{\alpha }\right)}^2{\left(\frac{\sin N\beta }{\sin \beta }\right)}^2,& \mathrm{Formula}\left(1\right)\end{array}$

where I₀ refers to an initial light intensity when the light irradiates the grating without bypassing the obstacle to continue to propagate.

$\frac{\sin \alpha }{\alpha }$

refers to a single-slit diffraction factor, and

$\frac{\sin N\beta }{\sin \beta }$

refers to a multi-slit interference factor. α satisfies:

$\alpha =\frac{\pi \mathrm{asin}\theta }{\lambda }.$

β satisfies:

$\beta =\frac{\pi d\sin \theta }{\lambda }.$

θ is a diffraction angle, Δ is a wavelength of light, N is the number of light-transmitting regions, and N is a positive integer greater than or equal to 1.

With reference to the above Formula (1), it can be seen that the single-slit diffraction is related to the width a of the light-transmitting region, and the multi-slit interference is related to the length d of one period of the grating. In addition, the multi-slit diffraction is a combined effect of the single-slit diffraction simultaneously generated by each single slit and the multi-light interference generated by parallel light diffracted by each single slit. The diffraction effect of the multi-slit diffraction can be reduced by reducing the width a of the light-transmitting region or increasing the length d of one period of the grating.

In some embodiments, a dark stripe of the single-slit diffraction satisfies: a×sin θ=±kλ, and a bright fringe of the multi-slit interference satisfies: d×sin θ=±kλ, where k is the diffraction order shown in FIG. 1 to FIG. 3.

In the related art, referring to FIG. 5 to FIG. 7, the transparent display panel includes: a plurality of pixel columns 001. There is no gap between multiple pixels included in each pixel column 001, and there is a gap between every two adjacent pixel columns 001. The gap between every two adjacent pixel columns 001 is a light-transmitting region, and light can pass through the gap between every two adjacent pixel columns. That is, the transparent display panel is regarded as a grating composed of multiple light-transmitting regions.

The gap c1 between two adjacent pixel columns 001 in FIG. 5 is smaller than the gap c2 between two adjacent pixel columns 001 in FIG. 6, and the gap c2 between two adjacent pixel columns 001 in FIG. 6 is smaller than the gap c3 between two adjacent pixel columns 001 in FIG. 7. That is, the width of the light-transmitting region in the transparent display panel shown in FIG. 5 is smaller than the width of the light-transmitting region in the transparent display panel shown in FIG. 6, and the width of the light-transmitting region in the transparent display panel shown in FIG. 6 is smaller than the width of the light-transmitting region in the transparent display panel shown in FIG. 7.

The diffraction effect of the transparent display panel shown in FIG. 5 is simulated as shown in FIG. 8, the diffraction effect of the transparent display panel shown in FIG. 6 is simulated as shown in FIG. 9, and the diffraction effect of the transparent display panel shown in FIG. 7 is simulated as shown in FIG. 10. It can be seen in conjunction with FIG. 8 to FIG. 10 that the ghost image of an image displayed on the transparent display panel shown in FIG. 5 is more obvious than that of the image displayed on the transparent display panel shown in FIG. 6, and the ghost image of the image displayed on the transparent display panel shown in FIG. 6 is more obvious than that of the image displayed on the transparent display panel shown in FIG. 7. That is, the diffraction effect of the transparent display panel shown in FIG. 5 is stronger than that of the transparent display panel shown in FIG. 6, and the diffraction effect of the transparent display panel shown in FIG. 6 is stronger than that of the transparent display panel shown in FIG. 7.

In the related art, by increasing the gap between adjacent pixel columns in the transparent display panel, the diffraction effect of the transparent display panel can be reduced. However, referring to FIG. 10, after increasing the gap between adjacent pixel columns in the transparent display panel, the ghost image of the image displayed on the transparent display panel is still obvious, and the display effect of the transparent display panel is poor.

The display panel according to some embodiments of the present disclosure can solve the problem of poor display effect of the display panel in the related art. Referring to FIG. 11, the display panel 10 includes: a base substrate 101 and a plurality of sub-pixel groups 102. The plurality of sub-pixel groups 102 are disposed on the base substrate 101 and arranged along a first direction A1. Four sub-pixel groups 102 are shown in FIG. 11. The sub-pixel group 102 includes a plurality of sub-pixels arranged along a second direction A2. The second direction A2 intersects the first direction A1. For example, the second direction A2 in FIG. 11 is perpendicular to the first direction A1.

Referring to FIG. 11, the plurality of sub-pixel groups 102 includes a first sub-pixel group 102a and a second sub-pixel group 102b which are adjacent to each other. The first sub-pixel group 102a includes two adjacent sub-pixels (X1 and X2) with a first interval h1 therebetween. The second sub-pixel group 102b includes two adjacent sub-pixels (Y1 and Y2) with a second interval h2 therebetween. The first interval h1 is different from the second interval h2.

The interval between two sub-pixels included in the sub-pixel group refers to the distance between the side of a first sub-pixel close to a second sub-pixel and the side of the second sub-pixel close to the first sub-pixel. Referring to FIG. 11, the first interval h1 between the sub-pixel X1 and the sub-pixel X2 refers to the distance between the side of the sub-pixel X1 close to the sub-pixel X2 and the side of the sub-pixel X2 close to the sub-pixel X1. The second interval h2 between the sub-pixel Y1 and the sub-pixel Y2 refers to the distance between the side of the sub-pixel Y1 close to the sub-pixel Y2 and the side of the sub-pixel Y2 close to the sub-pixel Y1.

In the embodiments of the present disclosure, the first interval h1 between the two adjacent sub-pixels (X1 and X2) in the first sub-pixel group 102a is different from the second interval h2 between the two adjacent pixels (Y1 and Y2) in the second sub-pixel group 102b, so the diffraction order of light passing through the gap between the two adjacent sub-pixels (X1 and X2) in the first sub-pixel group 102a is different from the diffraction order of the light passing through the gap between the two adjacent sub-pixels (Y1 and Y2) in the second sub-pixel group 102b. Therefore, the diffraction effect of the light emitting from the gap between adjacent sub-pixels can be reduced, and the display effect of the display panel 10 is better.

In summary, the embodiments of the present disclosure provide a display panel. In the display panel, the first sub-pixel group has two adjacent sub-pixels with the first interval, and the second sub-pixel group has two adjacent sub-pixels with the second interval. The first interval is different from the second interval, so that the diffraction order of the light passing through the gap between the two sub-pixels in the first sub-pixel group is different from that of the light passing through the gap between the two sub-pixels in the second sub-pixel group. Therefore, the diffraction effect can be reduced, and the display effect of the display panel is improved.

In some embodiments, the first direction A1 is a pixel column direction, and the second direction A2 is a pixel row direction. Certainly, the first direction A1 is a pixel row direction, and the second direction A2 is a pixel column direction, which is not limited in the embodiments of the present disclosure.

Referring to FIG. 12, it can be seen that the sub-pixels in the plurality of sub-pixel groups 102 are divided into a plurality of pixel islands. In some embodiments, referring to FIGS. 12 and 13, the plurality of pixel islands include a plurality of pixel island columns along the first direction A1 and a plurality of pixel island rows along the second direction A2; the pixel islands in a same column are aligned along the first direction A1, the pixel islands in a same row are aligned along the second direction A2, adjacent pixel islands are arranged in a staggered manner in columns and in rows.

Each of the pixel islands includes a pixel G. Each pixel G includes a plurality of sub-pixels, and there is a gap between two adjacent pixels G in the second direction A2. Thus, there is a gap between two adjacent sub-pixels in the sub-pixel group 102. The color of the combined light emitted from the plurality of sub-pixels included in each pixel is white.

In some embodiments, in the plurality of sub-pixels included in the pixel G in the display panel 10, there is a connecting line between two of the sub-pixels which intersects both the first direction A1 and the second direction A2. That is, the plurality of sub-pixels included in the pixel G are not arranged in the same direction (the first direction A1 or the second direction A2). In addition, in the plurality of sub-pixels included in each pixel, at least two sub-pixels belong to different sub-pixel groups.

Referring to FIG. 12, it can be seen that each pixel G includes a first sub-pixel g1, a second sub-pixel g2, a third sub-pixel g3, and a fourth sub-pixel g4. That is, the pixel G includes four sub-pixels. The first sub-pixel g1 and the second sub-pixel g2 are arranged along the first direction A1. The third sub-pixel g3 and the fourth sub-pixel g4 are respectively disposed on both sides of the first sub-pixel g1, and the third sub-pixel g3, the first sub-pixel g1, and the fourth sub-pixel g4 are arranged along the second direction A2.

Referring to FIG. 12, for each pixel G, the connecting line between the second sub-pixel g2 and the third sub-pixel g3, and the connecting line between the second sub-pixel g2 and the fourth sub-pixel g4 intersect both the first direction A1 and the second direction A2. For each pixel G, the first sub-pixel g1, the second sub-pixel g2, the third sub-pixel g3, and the fourth sub-pixel g4 are arranged in a “T” shape.

In some embodiments, in the four sub-pixels included in the pixel G, the color of at least one sub-pixel is red (R), the color of at least one sub-pixel is green (G), and the color of at least one sub-pixel is blue (B).

Exemplarily, the color of the first sub-pixel g1 is one of red and blue, the color of the second sub-pixel g2 is the other of red and blue, and the color of the third sub-pixel g3 and the color of the fourth sub-pixel g4 are both green. That is, in the four sub-pixels included in the pixel G, the color of one sub-pixel is red, the color of one sub-pixel is blue, and the color of the other two sub-pixels is green.

In the embodiments of the present disclosure, the pixel G includes less or more sub-pixels, which is not limited in the embodiments of the present disclosure, as long as the color of the combined light emitted from the plurality of sub-pixels included in the pixel G is white.

Referring to FIG. 12, it can be seen that the first sub-pixel group 102a includes: a plurality of first sub-pixels g1, a plurality of third sub-pixels g3, and a plurality of fourth sub-pixels g4, and the second sub-pixel group 102b includes: a plurality of second sub-pixels g2. The first interval h1 is smaller than the second interval h2.

In the embodiments of the present disclosure, referring to FIG. 12, the first pixel G1 and the second pixel G2 are adjacent to each other and are arranged along the second direction A2. The sub-pixels sequentially arranged along the second direction A2 in the first sub-pixel group 102a include: the third sub-pixel g3 of the first pixel G1, the first sub-pixel g1 of the first pixel G1, the fourth sub-pixel g4 of the first pixel G1, the third sub-pixel g3 of the second pixel G2, the first sub-pixel g1 of the second pixel G2, and the fourth sub-pixel g4 of the second pixel G2. Furthermore, the sub-pixels sequentially arranged along the second direction A2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the first pixel G1 and the second sub-pixel g2 of the second pixel G2.

The first pixel G1 and the second pixel G2 have a gap therebetween along the second direction A2. Referring to FIG. 12, the two adjacent sub-pixels with the first interval h1 therebetween in the first sub-pixel group 102a include: the fourth sub-pixel g4 of the first pixel G1 and the third sub-pixel g3 of the second pixel G2. That is, the fourth sub-pixel g4 of the first pixel G1 and the third sub-pixel g3 of the second pixel G2 have the first interval h1 therebetween along the second direction A2.

In addition, the two adjacent sub-pixels with the second interval h2 therebetween in the second sub-pixel group 102b include: the second sub-pixel g2 of the first pixel G1 and the second sub-pixel g2 of the second pixel G2. That is, the second sub-pixel g2 of the first pixel G1 and the second sub-pixel g2 of the second pixel G2 have the second interval h2 therebetween along the second direction A2.

In the embodiments of the present disclosure, the length of each sub-pixel included in the display panel 10 along the second direction A2 is the same. Referring to FIG. 11, the first interval h1 is equal to the length of one sub-pixel along the second direction A2, and the second interval h2 is equal to the length of three sub-pixels along the second direction A2. The white filling in FIG. 11 or FIG. 12 indicates that no sub-pixels are disposed.

Alternatively, referring to FIG. 13, the first interval h1 is equal to the length of two sub-pixels in the second direction A2, and the second interval h2 is equal to the length of four sub-pixels in the second direction A2.

The diffraction effect of the display panel shown in FIG. 11 is simulated as shown in FIG. 14, and the diffraction effect of the display panel shown in FIG. 13 is simulated as shown in FIG. 15. It can be seen in conjunction with FIG. 14 and FIG. 15 that the ghost image of the image displayed on the display panel shown in FIG. 11 is more obvious than the ghost image of the image displayed on the display panel shown in FIG. 13. That is, the display panel shown in FIG. 11 has a strong diffraction effect, and the display panel shown in FIG. 13 has a weak diffraction effect.

The diffraction effect of the display panel 10 is negatively correlated with the first interval h1 and the second interval h2. The larger the first interval h1 and the second interval h2 are, the weaker the diffraction effect of the display panel 10 is. The smaller the first interval h1 and the second interval h2 are, the stronger the diffraction effect of the display panel 10 is.

In the embodiments of the present disclosure, the first interval h1 and the second interval h2 are equal to the length of other numbers of sub-pixels along the second direction A2, which is not limited in the embodiments of the present disclosure. However, if the arrangement of the pixels in the display panel is the same as the arrangement shown in FIG. 11 and FIG. 13, and only the gap between adjacent pixels in the second direction A2 is adjusted (that is, the sizes of the first interval h1 and the second interval h2 are adjusted), the difference between the second interval h2 and the first interval h1 is equal to the length of two sub-pixels along the second direction A2.

That is, in the display panel 10 shown in FIG. 11 and FIG. 13, the first interval h1 and the second interval h2 satisfy: h2−h1=2×m, where m is the length of one sub-pixel along the second direction A2.

FIG. 16 is a schematic structural diagram of yet another display panel according to some embodiments of the present disclosure. It can also be seen with reference to FIG. 16 that the plurality of sub-pixel groups 102 further includes a third sub-pixel group 102c adjacent to the second sub-pixel group 102b. The third sub-pixel group 102c has two adjacent sub-pixels (Z1 and Z2) with a third interval h3 therebetween. Since the third sub-pixel group 102c is adjacent to the second sub-pixel group 102b, the third interval h3 is different from the second interval h2.

Referring to FIG. 17, it can be seen that the first sub-pixel group 102a includes: a plurality of first sub-pixels g1, a plurality of third sub-pixels g3, and a plurality of fourth sub-pixels g4. The second sub-pixel group 102b includes: a plurality of first sub-pixels g1, a plurality of second sub-pixels g2, a plurality of third sub-pixels g3, and a plurality of fourth sub-pixels g4. The third sub-pixel group 102c includes: a plurality of second sub-pixels g2. The third interval h3 is greater than the first interval h1, and the first interval h1 is greater than the second interval h2.

In the embodiments of the present disclosure, referring to FIG. 17, the first pixel G1, the second pixel G2, the third pixel G3, and the fourth pixel G4 are sequentially arranged along the second direction A2. The sub-pixels sequentially arranged along the second direction A2 in the first sub-pixel group 102a include: the third sub-pixel g3 of the first pixel G1, the first sub-pixel g1 of the first pixel G1, the fourth sub-pixel g4 of the first pixel G1, the third sub-pixel g3 of the third pixel G3, the first sub-pixel g1 of the third pixel G3, and the fourth sub-pixel g4 of the third pixel G3.

The sub-pixels sequentially arranged along the second direction A2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the first pixel G1, the third sub-pixel g3 of the second pixel G2, the first sub-pixel g1 of the second pixel G2, the fourth sub-pixel g4 of the second pixel G2, the second sub-pixel g2 of the third pixel G3, the third sub-pixel g3 of the fourth pixel G4, the first sub-pixel g1 of the fourth pixel G4, and the fourth sub-pixel g4 of the fourth pixel G4.

The sub-pixels sequentially arranged along the second direction A2 in the third sub-pixel group 102c include: the second sub-pixel g2 of the second pixel G2 and the second sub-pixel g2 of the fourth pixel G4.

Every two of the first pixel G1, the second pixel G2, the third pixel G3, and the fourth pixel G4 have a gap along the second direction A2. In conjunction with FIG. 16 and FIG. 17, the two adjacent sub-pixels with the first interval h1 in the first sub-pixel group 102a include: the fourth sub-pixel g4 of the first pixel G1 and the third sub-pixel g3 of the third pixel G3. That is, the fourth sub-pixel g4 of the first pixel G1 and the third sub-pixel g3 of the third pixel G3 have the first interval h1 along the second direction A2.

The two adjacent sub-pixels with the second interval h2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the first pixel G1 and the third sub-pixel g3 of the second pixel G2. Alternatively, the two adjacent sub-pixels with the second interval h2 in the second sub-pixel group 102b include: the fourth sub-pixel g4 of the second pixel G2 and the second sub-pixel g2 of the third pixel G3. Alternatively, the two adjacent sub-pixels with the second interval h2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the third pixel G3 and the third sub-pixel g3 of the fourth pixel G4.

That is, the second sub-pixel g2 of the first pixel G1 and the third sub-pixel g3 of the second pixel G2 have the second interval h2 along the second direction A2. The fourth sub-pixel g4 of the second pixel G2 and the second sub-pixel g2 of the third pixel G3 have the second interval h2 along the second direction A2. The second sub-pixel g2 of the third pixel G3 and the third sub-pixel g3 of the fourth pixel G4 have the second interval h2.

The two adjacent sub-pixels with the third interval h3 in the third sub-pixel group 102c include: the second sub-pixel g2 of the second pixel G2 and the second sub-pixel g2 of the fourth pixel G4. That is, the second sub-pixel g2 of the second pixel G2 and the second sub-pixel g2 of the fourth pixel G4 have the third interval h3.

Referring to FIG. 16 and FIG. 17, the first interval h1 is equal to the length of five sub-pixels along the second direction A2. The second interval h2 is equal to the length of two sub-pixels along the second direction A2. The third interval h3 is equal to the length of the seven sub-pixels along the second direction A2. The white filling in FIG. 16 and FIG. 17 indicates that no sub-pixels are disposed.

The two adjacent sub-pixels with the first interval h1 in the first sub-pixel group 102a include: the fourth sub-pixel g4 of the first pixel G1 and the third sub-pixel g3 of the third pixel G3.

That is, the fourth sub-pixel g4 of the first pixel G1 and the third sub-pixel g3 of the third pixel G3 have the first interval h1 along the second direction A2.

The two adjacent sub-pixels with the second interval h2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the first pixel G1 and the second sub-pixel g2 of the second pixel G2. Alternatively, the two adjacent sub-pixels with the second interval h2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the second pixel G2 and the second sub-pixel g2 of the third pixel G3. Alternatively, the two adjacent sub-pixels with the second interval h2 in the second sub-pixel group 102b include: the second sub-pixel g2 of the third pixel G3 and the second sub-pixel g2 of the fourth pixel G4.

That is, the second sub-pixel g2 of the first pixel G1 and the second sub-pixel g2 of the second pixel G2 have the second interval h2 along the second direction A2.

The white filling in FIG. 19 indicates that no sub-pixels are disposed.

In the embodiments of the present disclosure, the diffraction effect of the display panel shown in FIG. 19 is simulated as shown in FIG. 20. It can be seen with reference to FIG. 20 that the image displayed on the display panel 10 shown in FIG. 19 hardly has a ghost image. That is, the diffraction effect of the display panel 10 shown in FIG. 19 is weak, so that the display effect of the display panel 10 can be ensured.

Certainly, the first interval h1, the second interval h2, and the third interval h3 are equal to the length of other numbers of sub-pixels along the second direction A2, which is not limited in the embodiments of the present disclosure. However, if the arrangement of the pixels in the display panel is the same as the arrangement in FIG. 19, and only the gap between adjacent pixels in the second direction A2 is adjusted (that is, the sizes of the first interval h1, the second interval h2, and the third interval h3 are adjusted), the third interval h3 is equal to the first interval h1, and the first interval h1 is equal to the difference between twice the second interval h2 and the length of one sub-pixel along the second direction A2.

That is, in the display panel 10 shown in FIG. 19, the first interval h1, the second interval h2, and the third interval h3 satisfy: h1=h3=2×h2−m, where m is the length of one sub-pixel along the second direction A2.

In the embodiments of the present disclosure, the ratio of the area of regions where no sub-pixels are disposed in the display panel to the area of the display panel is an aperture ratio of the display panel. The transmittance of the display panel is positively correlated with the aperture ratio of the display panel. That is, the transmittance of the display panel is positively correlated with the area of the regions where no sub-pixels are disposed in the display panel. The larger the area of the regions where no sub-pixels are disposed in the display panel is, the higher the transmittance of the display panel is. The smaller the area of the regions where no sub-pixels are disposed in the display panel is, the lower the transmittance of the display panel is.

Exemplarily, the area of the regions where no sub-pixels are disposed in the display panel shown in FIG. 13 accounts for ½ of the area of the display panel (the aperture ratio is 50%). The area of the regions where no sub-pixels are disposed in the display panel shown in FIG. 16 and FIG. 18 accounts for ⅔ of the area of the display panel (the aperture ratio is approximately 66.7%). Therefore, the transmittance of the display panel shown in FIG. 16 and FIG. 18 is greater than the transmittance of the display panel shown in FIG. 13.

In summary, the embodiments of the present disclosure provide a display panel. In the display panel, the first sub-pixel group has two adjacent sub-pixels with the first interval, and the second sub-pixel group has two adjacent sub-pixels with the second interval. The first interval is different from the second interval, so that the diffraction order of light passing through the gap between the two sub-pixels in the first sub-pixel group is different from that of the light passing through the gap between the two sub-pixels in the second sub-pixel group. Therefore, the diffraction effect can be reduced, and the display effect of the display panel is improved.

The first interval h1 is different from the second interval h2.

In the embodiments of the present disclosure, the first interval h1 of the two adjacent sub-pixels (X1 and X2) in the first sub-pixel group 102a is different from the second interval h2 of the two adjacent sub-pixels (Y1 and Y2) in the second sub-pixel group 102b. Therefore, the diffraction order of light passing through the gap between two adjacent sub-pixels (X1 and X2) in the first sub-pixel group 102a is different from that of the light passing through the gap between two adjacent sub-pixels (Y1 and Y2) in the second sub-pixel group 102b. Hence, the diffraction effect of the light emitting from the gap between adjacent sub-pixels can be reduced, and the manufactured display panel 10 has a good display effect.

In summary, the embodiments of the present disclosure provide a method of manufacturing a display panel. In the display panel, the first sub-pixel group has two adjacent sub-pixels with the first interval, and the second sub-pixel group has two adjacent sub-pixels with the second interval. The first interval is different from the second interval, so that the diffraction order of light passing through the gap between the two sub-pixels in the first sub-pixel group is different from that of the light passing through the gap between the two sub-pixels in the second sub-pixel group. Therefore, the diffraction effect can be reduced, and the display effect of the display panel is improved.
