As mentioned in the background art, the color shift phenomenon of the main and sub display regions in the conventional display panel has a large viewing angle, and the inventor has found that the reason for this phenomenon is that the luminance decay rate of different color lights is different as the viewing angle is increased. The existing display panel with a relatively serious color cast at a viewing angle includes a display panel watched at a specific viewing angle, such as a vehicle-mounted display screen, and because the starting viewing angle of the display screen is relatively large, a relatively large color cast occurs when the viewing angle of a user is deviated. In addition, when the auxiliary display area is a bending display area and the main display area is a non-bending display area, an included angle exists between the bending area and the non-bending area. When the non-bending area is viewed in the front view, the bending area is in a large viewing angle state, and the brightness is greatly different from that of the non-bending area. Therefore, the brightness of the bending area with large visual angle is improved, and the color cast is improved.
Based on the above technical problem, the present embodiment provides the following solutions:
the present embodiment provides a display panel including: a substrate; a pixel defining layer including pixel defining structures arranged in an array on one side of the substrate; the display panel further comprises a main display area and an auxiliary display area arranged adjacent to the main display area, and the light emitting amount of the auxiliary display area is larger than that of the main display area.
The main display area is a plane display area relative to the auxiliary display area, and the auxiliary display area is a special-shaped display area or a non-plane display area.
The auxiliary display area which is adjacent to the main display area specifically comprises: the middle or the edge or any area of the main display area is provided with a secondary display area.
The auxiliary display area may be any area except the whole main display area, or may be a specific area with a severe color cast in the main display area, such as a bending area. Specifically, the secondary display area is: an edge display area or a deformable display area or a display area with a fixed curved surface or a slotted display area or a light-transmitting display area or a hole digging display area; the edge display area is a display area positioned at the peripheral edge of the main display area; the deformable display area refers to any area which can be used for folding or bending and is positioned in the main display area; the display area of the fixed curved surface is a curved surface display area positioned around the main display area, and the curved surface is a fixed curved surface; the slotted display area is an area on two sides of one end of the main display area, which is slotted, or a display area surrounding the slotted area, and the display color cast is caused because the size of the area is smaller than that of the main display area; the light-transmitting display area or the hole-digging display area can be a display area of an under-screen camera or an under-screen fingerprint area, the under-screen camera or the hole-digging display area has both an under-screen function and a display function, and the light transmittance of the display area is higher than that of the display areas of other areas, so that the display brightness is reduced, and the display color cast is caused.
When the sub-display region is a specific region with a severe color shift, the display panel may include one or more sub-display regions, and the light emitting amounts corresponding to the sub-display regions may be the same or different.
The specific view angle is an included angle between the sight line of the user and a perpendicular line of the surface of the array substrate far away from the first electrode.
Specifically, when the display panel is viewed at a specific viewing angle, since the viewing starting viewing angle is large, when the viewing angle of a user is shifted, a large color shift occurs, and by making the light output amount of the auxiliary display area larger than that of the main display area, when the user views the display panel at the specific viewing angle, a certain angle exists between the auxiliary display area and the main display area, so that the light output angle of the display panel can be changed to make the light output angle of the display panel consistent with or close to the angle at which the user views the display panel, thereby improving the light output amount of the auxiliary display area, reducing the chromaticity difference with the main display area, and improving the color shift of the display panel.
In addition, the auxiliary display area can be set as a bending area, and since the bending area has a certain angle deviation relative to the light emitting direction of the plane area, when the display panel is viewed at a larger viewing angle, the bending area and the plane area have a chromaticity difference. The light outlet angle of the bending area is almost consistent with the viewing angle of a user, and in addition, the light outlet brightness of the bending area is increased and is more than or equal to that of the main display area, so that the chromaticity difference between the bending area and the plane area is improved, and the color cast of the display panel is improved.
The light-emitting angle refers to an angle between an emergent light of the light-emitting layer and the light-emitting layer, and if the ray of the light-emitting layer is not shielded, the light-emitting angle is 90 degrees and is perpendicular to the light-emitting layer or is an angle formed between the emergent light of the light-emitting layer and the light-emitting layer; if the ray of the luminous layer is reflected by other layers, the angle of the ray reflected by other layers is defined as the light-emitting angle, at the moment, the light-emitting angle reflected by other layers is larger than the light-emitting angle not reflected, the reason is that most of visual angle rays cannot be emitted if the ray is not reflected due to shielding, the light reflected by the reflecting layer can firstly emit emergent light with a small angle, the emergent light is reflected by the reflecting layer without shielding, and the angle after reflection is larger at the moment. Therefore, the reflectivity is increased by changing the height, the angle and the space of the retaining walls at the two sides of the emergent light or increasing the reflecting film layer, and the included angle between the reflected light and the luminous layer can be greatly increased.
The present application describes embodiments of the present invention with reference to the following drawings:
fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention,
in a first embodiment of the present invention, a display panel includes: a substrate 10; the array layer 20 is positioned on one side of the substrate 10, a pixel defining layer 30 is arranged on one side of the array layer 20 far away from the substrate 10, and the pixel defining layer 30 comprises pixel defining structures arranged in an array.
The display panel further comprises a main display area 101, and a sub-display area 100 disposed adjacent to the main display area 101, the pixel defining structure comprising a plurality of first pixel defining structures 300 located in the sub-display area 100 and a plurality of second pixel defining structures 301 located in the main display area, the main display area 101 comprising a main light emitting layer 50 located between any two of the second pixel defining structures 301, the sub-display area 100 comprising a sub-light emitting layer 50 located between any two of the first pixel defining structures 300; wherein the reflectivity of at least one of the first pixel defining structures 300 is greater than the reflectivity of at least one of the second pixel defining structures 301, and the light output of the secondary display area 100 is greater than the light output of the primary display area 101.
Specifically, any two adjacent first pixel limiting structures 300 are provided with a sub-light emitting layer 50 between two opposite side surfaces, at least one of the two side surfaces is provided with a reflection film layer 40, preferably, the two opposite side surfaces are provided with the reflection film 40, and this scheme can be larger than the light emitting angle with which only one side surface is provided with the reflection film layer 40, and the application increases the reflectivity of the two side surfaces by arranging the reflection film layer in the light emitting direction of the sub-light emitting layer, so that the angle of light reflection can be increased, specifically: when the light emitting angle of the light emitting layer is reflected to the side of the first pixel defining structure 300, the amount of light emitted after reflection is increased by reflection through the reflection surface having the reflection film layer 40. The light output quantity of the auxiliary display area 100 is increased, so that the light output brightness of the auxiliary display area is increased, and the color cast of the auxiliary display area is improved.
The embodiment of the application sets up the reflectance coating through the pixel of luminescent layer both sides is injectd the structure both sides, increases the reflectivity of two sides, can restrict the light-emitting and go out through the multiple reflection of the reflectance coating of great reflectance coating between the structure at two pixels, and the light yield that reflects away is far greater than the light yield that does not set up the reflectance coating, increases the light-emitting simultaneously.
The reflective film 40 described in the embodiment of the present application has two modes, the first mode: between the side surface and the light emitting layer 50; the second mode is as follows: is located on the side surface and is located on the light-emitting side of the light-emitting layer 50 far away from the substrate 10. The two methods have different processes and different light output amounts. Specifically, when the first method is adopted, the reflective film layer 40 is located between the side surface and the light emitting layer 50, in the process, the reflective film layer 40 is coated on the first pixel defining structures 300, and then the light emitting layer 50 is deposited between two adjacent first pixel defining structures 300; when the second method is adopted, the reflective film layer 40 is located on the side surface and only located on the light-emitting side of the light-emitting layer 50 far away from the substrate 10, in the process, the light-emitting layer 50 is deposited between two adjacent first pixel defining structures 300, and then the reflective film layer 40 is coated on the non-light-emitting layer part of the side surface.
In the first process, a part of the coated reflective film layer 40 is blocked by the light emitting layer 50, so that the reflectivity of the first pixel defining structure of the first process is slightly reduced but is greater than that of the second pixel defining structure 301 without coating the reflective layer. In the second process, the reflective layer 40 is directly coated on the side surface of the first pixel defining structure 300 on the light emitting side of the light emitting layer 50, and the reflective layer 40 is not blocked, so that the reflectivity of the first pixel defining structure in the second process is not changed and is greater than that of the first pixel defining structure in the first process; therefore, the light output amount of the second mode is larger than that of the first mode. The applicant can set the reflective film layer with any structure according to the light output quantity which needs to be regulated, as long as the light output quantity of the auxiliary display area can be increased.
The reflective film layer 40 is a metal film, such as silver (Ag), aluminum (Al), platinum (Pt), gold (Au), chromium (Cr), tungsten (W), molybdenum (Mo), titanium (Ti), palladium (Pd), or an alloy of these metals. The reflectivity of the first pixel limiting structure with the reflecting film is (100%), the emergent light of the light-emitting layer is limited between the first pixel limiting structures with the reflecting film, and the emergent light can be totally reflected out through different reflection angles by the reflecting films arranged on two sides so as to reflect the emergent light with large angles. Therefore, the light emitted from the light emitting layer is reflected by the reflective film layer 40 of the first pixel defining structure 300 to generate a larger amount of light than the second pixel defining structure 301 without a reflective film.
As shown in fig. 1-2, the second embodiment provided in the present application may or may not be further improved on the basis of the above-mentioned embodiment.
The method specifically comprises the following steps: the display panel includes: a substrate 10; an array layer 20 on one side of the substrate, a pixel defining layer 30 disposed on one side of the array layer 20 away from the substrate 10, the pixel defining layer 30 including pixel defining structures arranged in an array, and the display panel including a light emitting layer 50 between adjacent pixel defining structures. The display panel further comprises a main display area 101, and a sub-display area 100 arranged adjacent to the main display area 101, wherein the pixel defining structures comprise a plurality of first pixel defining structures 300 located in the sub-display area 100 and a plurality of second pixel defining structures 301 located in the main display area 101, the main display area 101 comprises a main light emitting layer 50 located between any two of the second pixel defining structures 301, the sub-display area 100 comprises a sub-light emitting layer 50 located between any two of the first pixel defining structures 300, and the light output amount of the sub-display area 100 is larger than that of the main display area 101.
Two opposite side surfaces of any adjacent two of the first pixel defining structures 300 located in the sub display area 100 are parallel to each other; or one ends of the two side surfaces far away from the substrate are respectively extended and intersected to form a virtual included angle; preferably, the angle of the virtual included angle is 0-45 °. According to the embodiment of the application, the problem of color cast of the auxiliary display area is improved by increasing the light-emitting angle and the light-emitting brightness of the auxiliary light-emitting layer of the auxiliary display area after the auxiliary light-emitting layer is reflected by two side surfaces which are parallel to each other or intersected by a virtual extension surface. The preferable effect of the two schemes is that two side surfaces are parallel to each other, and the scheme specifically comprises the following steps: when the two side surfaces are parallel, the distance between the two side surfaces is reduced compared with the previous distance, emergent light is reflected between the two side surfaces at the same smaller angle, and the angle after reflection is increased compared with the angle of the smaller angle emitted before, in addition, the scheme can also easily reflect the existing light which is blocked and does not emit light, and the light emitting brightness is increased; when the virtual extension surfaces of the two side surfaces are intersected, the distance between the two side surfaces is smaller than the parallel distance, and the angle of light reflected out is smaller than the reflection angle of the two side surfaces in parallel; the light emitting angle of the virtual extension surfaces is larger than the light emitting angles parallel to each other, but the light emitting effect is affected because the scheme of the virtual extension surfaces intersecting is easy to generate total reflection, so that the light emitting display effect parallel to each other is superior to the scheme of the virtual extension surfaces intersecting. The inventor can freely select the scheme to be designed according to the design requirement.
And the light-emitting angle and the light-emitting brightness of the sub light-emitting layer of the sub display area are increased after the sub light-emitting layer is reflected by two side surfaces which are parallel to each other or are intersected by a virtual extension surface. The specific reasons are as follows: the distance between the two side surfaces is smaller than the distance between the two adjacent second pixel limiting structures, the light-emitting angle of the auxiliary display area is reflected by one side surface of the two side surfaces and then rebounded to the other side surface, and is reflected to one side surface from the other side surface, so that the light is reflected back and forth for multiple times, and the light-emitting angle of small-angle emergent light emitted after being reflected is inevitably increased; in addition, the reflection times of the light emitted by the light emitting layer reflect all the large-angle emergent light originally limited between the two adjacent first pixel limiting structures, and the angles of the emergent light are increased by different reflection angles. Therefore, the light-emitting angle of the secondary display area is increased, and the light-emitting amount is increased, so that the light-emitting brightness of the secondary display area is increased.
Two opposite side surfaces of any adjacent two of the first pixel defining structures 300 are parallel to each other. Specifically, when two opposite side surfaces (300a, 300b) of any two adjacent first pixel defining structures 300 are parallel to each other, each first pixel defining structure 300 includes a first surface close to the substrate and a second surface far from the substrate, and the size of the first surface of one first pixel defining structure 300b of any two adjacent first pixel defining structures is smaller than that of the second surface; the first surface size of the other one of any adjacent two first pixel defining structures 300a is larger than the second surface size.
Preferably, the second surface dimension of the one pixel defining structure 300b away from the substrate is larger than the first surface dimension thereof close to the substrate, and the second surface dimension of the other pixel defining structure 300a away from the substrate is smaller than the first surface dimension thereof close to the substrate. Wherein the first surface dimension of the one first pixel defining structure 300b is equal to the second surface dimension of the other first pixel defining structure 300 a; the second surface size of the one first pixel defining structure 300b is equal to the first surface size of the other first pixel defining structure 300 a.
Preferably, a shape or a direction of one first pixel defining structure 300a of the two arbitrary adjacent first pixel defining structures is the same as a shape or a direction of the second pixel defining structure 301, a shape of another first pixel defining structure 300b of the two arbitrary adjacent first pixel defining structures is the same as a shape of the second pixel defining structure 301 rotated by 180 ° in a horizontal direction, and a direction of the another first pixel defining structure 300b is opposite to the direction of the second pixel defining structure 301.
Preferably, the pixel defining structures are trapezoid structures or triangle structures, and a plurality of the first pixel defining structures 300 are alternately arranged by at least one first pixel defining structure 300a having a regular trapezoid shape and at least one first pixel defining structure 300b having an inverted trapezoid shape; the plurality of second pixel defining structures 301 are arranged in an array of a plurality of right trapezoidal second pixel defining structures 301; when all the pixel defining structures are triangular, the plurality of first pixel defining structures 300 are alternately arranged by at least one regular triangular first pixel defining structure 300a and at least one inverted triangular first pixel defining structure 300b, and the plurality of second pixel defining structures 301 are arranged by a plurality of regular triangular second pixel defining structures in an array.
The arrangement mode of the existing pixel limiting structure is changed in the auxiliary display area, and the scheme that two side faces of the light emitting layer are parallel to each other is realized through the alternating design of the regular trapezoid and the inverted trapezoid, so that the light emitting amount is increased, and the design scheme is simple.
When two opposite side surfaces of any two adjacent first pixel defining structures 300 are arranged, the ends of the two side surfaces far away from the substrate respectively extend and intersect to form a virtual included angle; preferably, the angle of the virtual included angle is (0-45) °, and the angle range of the virtual included angle is (15-45) °. In this angle range, the interval between two sides is close to substrate one side and is greater than the interval of keeping away from substrate one side, and the light-emitting angle after the emergent light of the same angle reflects between the side of less interval is bigger, and the light-emitting volume is bigger, and light-emitting luminance increases, and the light-emitting effect is better, vice display area with colour difference between the main display area is not obvious.
Specifically, each of the first pixel defining structures 300 includes a first surface close to the substrate and a second surface far from the substrate, and the size of the first surface of one first pixel defining structure 300b in any two adjacent first pixel defining structures is smaller than that of the second surface; the first surface size of the other one of any adjacent two first pixel defining structures 300a is larger than the second surface size. Wherein the first surface size of the one first pixel defining structure 300b is smaller than the second surface size of the other first pixel defining structure 300 a; the second surface size of the one first pixel defining structure 300b is larger than the first surface size of the other first pixel defining structure 300 a; the design is such that the ends of the two opposite side surfaces of any two adjacent first pixel defining structures 300 far away from the substrate respectively extend and intersect to form a virtual included angle.
Preferably, a shape or a direction of one of the two arbitrary adjacent first pixel defining structures 300 is the same as a shape or a direction of the second pixel defining structure 301, and a direction of the other one of the two arbitrary adjacent first pixel defining structures 300b is the same as a direction in which the second pixel defining structure is rotated by 180 ° in a horizontal direction, but is different in shape. The other first pixel defining structure 300b is shaped as a structure having a large top and a small bottom, and the size of the top is larger than that of the bottom of the adjacent one of the first pixel defining structures 300a, and the size of the bottom is smaller than that of the top of the adjacent one of the first pixel defining structures 300 a.
According to the design, the scheme of the virtual included angle can be realized only by adjusting the side inclined angle of one inverted trapezoid in the two adjacent first pixel limiting structures on the scheme that the two sides are parallel to each other, and the design scheme is simple.
In the third embodiment, on the basis of the second embodiment (changing the arrangement of the first pixel defining structures in the secondary display area), a reflective film layer may be further disposed in the secondary display area, at least one of two side surfaces of any two adjacent first pixel defining structures 300a and 300b is provided with a reflective film layer 40, and the reflective film layer is formed of a metal film, such as silver (Ag), aluminum (Al), platinum (Pt), gold (Au), chromium (Cr), tungsten (W), molybdenum (Mo), titanium (Ti), palladium (Pd), or an alloy of these metals.
The reflectivity of the first pixel limiting structure with the reflecting film is 100%, the reflecting film layer is added on the basis of the second embodiment, the light emitting quantity of the auxiliary display area is increased by adjusting the first pixel limiting structure to increase the light emitting reflection times of the light emitting layer, and the light emitting quantity of the auxiliary display area is increased.
As shown in fig. 3, in the fourth embodiment provided in the present application, on the basis of the second embodiment (changing the arrangement manner of the first pixel defining structures in the sub display region), the included angle a1 and/or the height h1 between the side surface of the first pixel defining structure 300 in the sub display region 100 and the substrate 10 may also be changed. Specifically, the two arbitrary adjacent first pixel defining structures 300 have two opposite sides between which the light emitting layer 50 is located; wherein an included angle a1 between at least one of the two side faces and the substrate is smaller than an included angle a2 between the two opposite side faces of the any two adjacent second pixel defining structures 301 and the substrate 10; and/or the height h1 of at least one of the first pixel defining structures 300 is less than the height h2 of at least one of the second pixel defining structures 301.
Preferably, an included angle a1 between the at least one side surface and the substrate 10 is in a range of 30 ° to 45 °, an included angle a2 between two opposite side surfaces of any two adjacent second pixel defining structures 301 and the substrate 10 is 45 °, a height h1 of at least one of the first pixel defining structures 300 is in a range of 1um to 1.5um, and a height h2 of at least one of the second pixel defining structures 301 is in a range of 1.5 um.
