Embodiment one:
as shown in fig. 1, in a first aspect, a display panel is provided in accordance with an embodiment of the present application, which is applied to a display device having an under-screen image collector, and includes: the second display area 20 and the first display area 10 corresponding to the off-screen image collector, and each first pixel 11 in the first display area 10 comprises a plurality of first sub-pixels 111; each second pixel 21 in the second display area 20 includes a plurality of second sub-pixels 211; the pixel density of the first display area 10 is equal to that of the second display area 20, the sub-pixel area of the first display area 10 is a1, and the sub-pixel area of the second display area 20 is a2, wherein a1 is less than or equal to a2. Under the condition of adopting equal pixel density, the aim of increasing the light transmittance is achieved by reducing the area ratio of the sub-pixels of the first display area 10, and under the condition of unchanged pixel density, the display effect is hardly influenced, the requirements of the display panel on the light transmittance and the display effect can be met at the same time, and the image collector under the screen can collect images better. The application effectively solves the problem that the display panel in the prior art can not meet the requirements on light transmittance and display effect at the same time.
The subpixel area ratio is a ratio of a sum of areas of all subpixels in a single pixel to an area of a single pixel, or a ratio of a light emitting area in a single pixel to an area of a single pixel. Under the condition that the pixel density is the same, the area of the non-luminous area is correspondingly increased due to the fact that the area occupation ratio of the sub-pixels is relatively reduced, so that the light transmittance is increased, more external light can enter the image collector under the screen, and the collection function can be better played. Meanwhile, the pixel density is not reduced, the joint display effect of the sub-pixels with the same color in the actual display effect is not greatly influenced, the display effect of the region of the image collector under the screen is not greatly changed, serious shadows or saw teeth are not generated, the display effect of the high-region is further improved, and a user can obtain better display experience in the application process.
Further, in the technical scheme of the first embodiment, the sub-pixel area of the second display area 20 is in the range of 20% to 90% of a2. The subpixel area ratio of the second display area 20 is within the above range, so that the display panel has a good display effect, and the larger the value of the subpixel area ratio is, the better the display effect of the pixel combination is, and the clearer the displayed line profile and the like are.
In an alternative embodiment, the subpixel area ratio is between 25% and 45%, and the subpixel area ratio is in a range that satisfies the current requirements for display effect and compatibility choices with other accessories, where 40% of the subpixel area ratio is the most effective.
In another alternative embodiment, the subpixel area ratio is between 70% and 90%, and the improvement of the subpixel area ratio is an effective way to improve the display effect, and under the condition that the pixel area and the subpixel area are gradually reduced, the improvement of the subpixel area ratio is relatively difficult, and the subpixel area ratio is set between 70% and 90%, so that the displayed image is clearer, the detail processing has more operable space, the color adjustment effect is more obvious, and the method is more suitable for terminal equipment with high display requirements.
In the technical scheme of the first embodiment, the ratio of the sub-pixel area ratio a1 of the first display area 10 to the sub-pixel area ratio a2 of the second display area 20 is in the range of 0.278-1/a 2-1, and 25-1. The arrangement ensures that the sub-pixel area ratio a1 in the first display area 10 can meet the requirement of the display effect, and the sub-pixel area ratio of the second display area 20 can be adjusted, so that the light transmittance of the first display area 10 is effectively improved compared with that of the whole display panel, the display effect of the first display area 10 is not greatly influenced, the experience of a user is further improved, and the arrangement is more beneficial to realizing the manufacture and arrangement of pixels.
Further, in the embodiment of the first embodiment, the ratio of the sub-pixel area ratio a1 of the first display area 10 to the sub-pixel area ratio a2 of the second display area 20 is in the range of 0.5 to a1/a2 to 0.9. By the arrangement, the pixel display variation degree between the first display area 10 and the second display area 20 can be reduced, obvious partition behaviors of the display effect are avoided, and the risk of uneven display effect is reduced.
In the first embodiment, the first pixel 11 includes a first sub-pixel 111 with multiple colors, the second pixel 21 includes a second sub-pixel 211 with multiple colors, the ratio of the area of the first sub-pixel 111 with the first color to the area of the second sub-pixel 211 with the first color is b1, the ratio of the area of the first sub-pixel 111 with the second color to the area of the second sub-pixel 211 with the second color is b2, and the ratio of the area of the first sub-pixel 111 with the third color to the area of the second sub-pixel 211 with the third color is b3, b1=b2=b3. The arrangement is such that the area ratio between the first sub-pixels 111 of each color in each pixel is kept uniform, and the ratio of the sub-pixels of each color of the pixels in the first display area 10 and the second display area 20 is also the same, so that the display effect can be kept uniform, and the pixels can be controlled to form a proper color arrangement combination, so that the display effect is more uniform.
It should be noted that, as shown in fig. 2, a plurality of areas are disposed in a single pixel for arrangement of sub-pixels, and the first pixel 11 or the second pixel 21 includes at least three sub-pixels, and of course, there may be cases where the total area of the pixels is kept consistent, the area ratio of the sub-pixels changes only in the arrangement area of the sub-pixels, and the arrangement may be such that the sizes of three or more sub-pixels in each pixel become smaller synchronously, so that the pixels can be sequentially arranged, and all the pixels on the panel are formed in arrays along two mutually perpendicular directions in the horizontal direction.
The first sub-pixel 111 of a plurality of colors and the second sub-pixel 211 of a plurality of colors refer to sub-pixels capable of exhibiting different colors, wherein the first color, the second color and the third color may be one of three colors of red, blue and green, that is, RGB color patterns, various colors are obtained by the variation of three color channels and the superposition thereof with each other, or the plurality of colors may further include sub-pixels of other colors directly displayed, for example, white, yellow, etc., that is, the kind of the first sub-pixel 111 and the kind of the second sub-pixel 211 are not limited to only three colors and are not limited to the case of only three sub-pixels within a single pixel. For example: in a specific embodiment, the ratio of the area of the first subpixel 111 of the fourth color to the area of the second subpixel 211 of the fourth color is b4, b1=b2=b3=b4.
As shown in fig. 1, in the technical solution of the first embodiment, the first display area 10 is provided with a first display area 12 and a second display area 13 that are adjacent, the area ratio of the sub-pixels in the first display area 12 is a3, and the area ratio of the sub-pixels in the second display area 13 is a4, and a3/a4 is 0.8-1.2. Such an arrangement is used for area allocation of pixels within the first display area 10, and in the case of meeting the requirements of the first display area 10, the light transmittance is increased by the change of the sub-pixel area ratio with a gradient, while the occurrence of the situation that the display effects are significantly different due to the change of the sub-pixel area ratio is reduced.
It should be noted that, in the above arrangement, the pixel arrangement in the first display area 10 has a gradient change, and the display area in the second display area 20 may form a transition area with a sub-pixel area ratio close to the second display area 20, so as to avoid abrupt change of display and improve display uniformity.
As shown in fig. 1, in the technical solution of the first embodiment, the first display area 12 and the second display area 13 are plural, and the first display area 12 is disposed at a distance from the second display area 13. Such a setting increases a plurality of gradient settings in the first display area 10, further reduces the influence of different display effects due to reduction of the sub-pixel area ratio, on the one hand, the light transmittance of external light can be increased, on the other hand, the display effect can be ensured to be close to or consistent with that of the normal second display area 20, and better experience can be brought to a user.
As shown in fig. 1, in the technical solution of the first embodiment, the second display area 13 is disposed around the first display area 12, and the manner of surrounding the first display area 12 can be matched with the design of the light transmission position, so that the light transmission amount in the first display area 10 can be increased in a targeted manner. Specifically, the first display area 12 in the first embodiment includes the circular first display area 12, the annular second display area 13, the annular first display area 12 and the annular second display area 13 from inside to outside, the sub-pixel area ratio a3 of the first display area 12 is smaller than the sub-pixel area ratio a4 of the second display area 13, and this arrangement makes the transmittance of the center area highest, and the pixel area ratio of the display area in contact with the second display area 20 at the outermost side is highest, so that no large pixel area ratio change occurs, and the display effect abrupt change is avoided.
In the first embodiment, the difference between the sub-pixel area ratio a3 of the first display area 12 and the sub-pixel area ratio a4 of the second display area 13 is equal to the difference between the sub-pixel area ratio a4 of the second display area 13 and the sub-pixel area ratio a2 in the second display area 20, that is, the sub-pixel area ratios of the first display area 12, the second display area 13 and the second display area 20 change in the same rule.
In the technical scheme of the first embodiment, under the condition that the pixel density is unchanged, the size of the pixels is gradually changed, and pixel arrays with different area ratios are arranged at intervals so as to change the shielding of the pixel electrodes. Meanwhile, the deposition range of the OLED luminescent device can be synchronously reduced on the basis, and the light transmittance is further increased. The method is suitable for the design of the pixels of the display panel of the under-screen image collector, and improves the light intensity of an external light source entering the image collector through the display screen. The gradient improves the pixel size to increase the light transmission amount without changing the pixel density, so that the display effect can be maintained as much as possible and the light transmission amount can be increased. On the other hand, the manufacturing process difficulty and the manufacturing process cost are not increased.
The method has the advantages that the size of the anode region of the pixel can be effectively reduced, the shielding of external light is further weakened, the light quantity is increased, and the shooting effect is enhanced; meanwhile, the scheme does not cause too much degradation of the display quality in the area, and is superior to other schemes (reducing the pixel density or reducing the size as a whole) in display effect.
Further description of embodiment one:
the first display area 10 is divided into four display areas, namely a first display area 12, a first second display area 13, a second first display area 12 and a second display area 13 from inside to outside, wherein the area ratio of the sub-pixels is R01, R02, R03 and R04, and the area ratio of the sub-pixels is the ratio of the sum of the areas of 3 or more sub-pixels in each pixel to the area of a single pixel. The area ratio of the sub-pixels in the region is designed to be r01=r03 < r02=r04 < a2 (the area ratio of the sub-pixels in the second display region 20), so the requirement is that the pixels in the R04 region are close to the normal display region, so that in order to avoid abrupt change of display, a design manner of gradually changing the area ratio is adopted, and the technical scheme of the first embodiment may be as follows:
r01=r03=50% a2, r02=r04=75% a2; also, r01=r03=60% a2, r02=r04=80% a2; also, r01=r03=70% a2, r02=r04=85% a2; not limited to the above isocratic rule, it is also possible to adopt a design scheme of a non-isocratic gradient such as r01=r03=70% a2, r02=r04=90% a2, and the like.
Of course, the pixel dividing areas of the first display area 10 are not limited to 4, but may be multiple groups of dividing areas, but need to be maintained in a spaced distribution manner, that is, a large-small distribution manner, and of course, are not limited to one area, but may be two areas with large area ratio, and then one area with small area ratio; or a region with a large area ratio and two regions with a small area ratio; after 3 areas with large area ratio, two areas with small area ratio can be adopted; two regions having a large area ratio may be followed by 3 regions having a small area ratio.
It should be noted that, the display panel in the first embodiment may be an organic light emitting diode (Organic Light Emitting Diode, OLED) display panel.
Embodiment two:
as shown in fig. 3, the difference between the technical solution of the second embodiment and the first embodiment is that the center of the first display area 12 is a rectangular first display area 12, the first display area 12 is disposed at the center of a rectangular first second display area 13, the first second display area 13 is disposed at the center of a rectangular second first display area 12, the second first display area 12 is disposed at the center of a rectangular second display area 13, that is, all display areas are disposed in a rectangular structure, the rectangular arrangement is more favorable for matching with rectangular pixel arrangement, and the arrangement is more convenient in the position where the pixels change.
Embodiment III:
as shown in fig. 4, in the third embodiment, the first display area 12 and the second display area 13 are rectangular areas, and the first display area 12 and the second display area 13 are disposed at intervals. This arrangement keeps the gradient change in the first display area 10 uniform, and the light transmission effect can be kept consistent throughout the whole area, so that the display effect is more stable, and the actual display condition allocation is facilitated. The display area of the display area that is in contact with the second display area 20 at the outermost side has the highest pixel area ratio, and no large pixel area ratio change occurs, so that the abrupt change of the display effect is avoided.
Further illustrating embodiment three:
in the third embodiment, the technical solution is mainly that the strip-shaped area is divided into 8 areas in turn, and the strip-shaped areas correspond to the first display area 12, the first second display area 13, the second first display area 12, the second display area 13, the third first display area 12, the third second display area 13, the fourth first display area 12 and the fourth second display area 13 respectively, and the sub-pixel area ratio of the strip-shaped areas is R01, R02, R03, R04, R05, R06, R07, R08, and the design rule refers to the above embodiment, and r01=r03=r05=r07 < r02=r04=r06=r08 < a2 (the sub-pixel area ratio of the second display area 20 may be r01=r03=r07=50% -a 2, r02=r04=r06=r08=a2); may also be
R01=r03=r05=r07=60% a2, r02=r04=r06=r08=80% a2; may also be
R01=r03=r05=r07=70% a2, r02=r04=r06=r08=85% a2; not limited to the above gradient law, a non-gradient design scheme such as r01=r03=r05=r07=70% a2, r02=r04=r06=r08=90% a2, and the like may be adopted.
Embodiment four:
as shown in fig. 5, in the fourth embodiment, the first display area 12 and the second display area 13 are rectangular areas, and the first display area 12 and the second display area 13 are disposed at intervals. The difference from the third embodiment is that the connection position with the second display area 20 is disposed on the side of the first display area 12 alternating with the second display area 13, and the arrangement can form three groups of pixels with different pixel area ratios at the connection position, so that the function of pixel combination display is increased, the influence of display mutation can be reduced, and the display stability is increased.
Fifth embodiment:
as shown in fig. 6, in the technical solution of the fifth embodiment, the first display area 10 is sequentially provided with a third display area 14, a fourth display area 15 and a fifth display area 16 along a side of the second display area 13 away from the first display area 12, where the area ratio of the sub-pixels of the third display area 14 is a5, the area ratio of the sub-pixels of the fourth display area 15 is a6, the area ratio of the sub-pixels of the fifth display area 16 is a7, a3-a4=a4-a5=a5-a6=a6-a 7, and 0.8 is less than or equal to a3/a7 is less than or equal to 1.2. The arrangement further thins the change of the area ratio of the sub-pixels in the first display area 10, further reduces the influence of display mutation caused by the change of the area ratio of the sub-pixels, and ensures the display effect.
Specifically, the first display area 12, the second display area 13, the third display area 14, the fourth display area 15 and the fifth display area 16 are rectangular areas, the sub-pixel area occupation ratio of the display areas gradually increases along the direction approaching the second display area 20, the sub-pixel area occupation ratio a7 of the fifth display area 16 is equal to the sub-pixel area occupation ratio of the second display area 20, or the difference between the sub-pixel area occupation ratio a7 of the fifth display area 16 and the sub-pixel area occupation ratio of the second display area 20 is equal to the difference between the sub-pixel area occupation ratio a7 of the fifth display area 16 and the sub-pixel area occupation ratio of the fourth display area 15, so as to maintain the numerical variation degree of the variation position and ensure the display effect.
It should be noted that the display panel may include a plurality of first display regions 10 disposed in succession, that is, the first display region 12, the second display region 13, the third display region 14, the fourth display region 15, and the fifth display region 16 are disposed in a cyclic manner, and in such a configuration, the maximum gradient difference between the sub-pixel area ratio a3 of the first display region 12 and the sub-pixel area ratio a7 of the fifth display region 16 cannot exceed twenty percent, that is, it is required to satisfy 0.8+.a3/a7+.1.2, and such a configuration reduces and avoids the problem that the display effect of the display panel is broken due to abrupt gradient change between the plurality of first display regions 10.
In an alternative embodiment, where the absolute value of a3-a4 is equal to the absolute value of a4-a5, the absolute value of a4-a5 is equal to the absolute value of a5-a6, and the absolute value of a5-a6 is equal to the absolute value of a6-a7, the arrangement allows for cyclic gradient changes, i.e., using the first display region 12, the second display region 13, the third display region 14, the fourth display region 15, the fifth display region 16, the fourth display region 15, the third display region 14, the second display region 13, and the first display region 12 in order from left to right as shown in fig. 5, which avoids abrupt changes, forms different display region distributions in a manner similar to a sine function, and avoids large sub-pixel area ratio changes between the display regions.
In the fifth embodiment, the first display area 10 is divided into five display areas, and the spans of the sub-pixel area ratios of the first display area 12 and the fifth display area 16 are relatively large when in use, which is not suitable for
Example six:
as shown in fig. 7, in the technical solution of the sixth embodiment, the first display area 10 includes, from top to bottom, the first display area 12, the second display area 13, the third display area 14, the fourth display area 15, the fifth display area 16, the fourth display area 15, the third display area 14, the second display area 13, and the first display area 12, which are sequentially adopted, and the same point as that of the fifth embodiment is that the occurrence of the abrupt change can be avoided, and the stability of the display effect is ensured. The difference from the fifth embodiment is that the connection position with the second display area 20 is disposed on the side of the first display area 12 alternating with the second display area 13, and the arrangement can form three groups of pixels with different pixel area ratios at the connection position, so that the function of pixel combination display is increased, the influence of display mutation can be reduced, and the display stability is increased.
In a second aspect, the present application further provides a display device, where the display device includes a display panel and an image collector, the display panel is a display panel of any one of the first to sixth embodiments, and the image collector is located on a side of the display panel facing away from the display surface. By adopting the display device of the display panel of any embodiment, the image acquisition function of the image acquisition device under the screen can be better realized, the display function of the display device can be considered, and better visual experience is provided for a user. The display device can be applied to mobile terminals such as mobile phones and tablet computers, and accessories or equipment with display functions such as computers and intelligent wearable equipment.
