According to the application, the reflection layer 170 is arranged in the peep-proof region 120 of the display panel 100 at the position corresponding to the light shielding layer 160 above the peep-proof sub-pixel 150, so that the reflection layer 170 is positioned below the light shielding layer 160 and corresponds to the second anode 151 in the peep-proof sub-pixel 150, when the peep-proof sub-pixel 150 is started, light emitted by the second light emitting layer 152 in the peep-proof sub-pixel 150 is emitted to the reflection layer 170, the reflection layer 170 reflects the light to the peep-proof large view angle range for peep-proof brightness compensation, meanwhile, the light emitted by the second light emitting layer 152 downwards is reflected to the peep-proof large view angle range for peep-proof brightness compensation through the second anode 151, in the process, part of the light is emitted to the second anode 151, the second anode 151 is further adjusted to the large view angle range and the reflection layer 170 after the direction of the light is adjusted, and meanwhile, the part of the light is emitted to the reflection layer 170, and the second anode 151 is further emitted to the large view angle range after the direction is adjusted, and the reflection layer 170 is further, the light can enter the peep-proof region 120 through the matching between the reflection layer 170 and the second anode 151, and the peep-proof region 120 can be more improved, and the peep-proof effect can be achieved.
In fig. 2, a represents light emitted upward from the first light emitting layer, B represents light emitted downward from the first light emitting layer, and since light emitted from the second light emitting layer is the same as the light emitted from the first light emitting layer, the light emitted from the second light emitting layer is not shown to avoid mixing the light paths and influence understanding, C represents light reflected between the reflective layer and the second anode, C1 represents light emitted from the second anode to the reflective layer and reflected from the reflective layer to the peep-preventing region, and C2 represents light directly reflected from the second anode to the peep-preventing region.
Based on the above, in the present application, the brightness of the peep-proof area 120 is improved by the way that the reflective layer 170 and the second anode 151 are mutually matched, and it is notable that, in practice, the first anode 131 in the present application also reflects light to perform adjustment treatment, that is, the present application adopts the way that the reflective layer 170, the first anode 131 and the second anode 151 are mutually matched to improve the uniformity of the display brightness of the display panel 100 and improve the peep-proof brightness in the peep-proof mode, the specific principle is as follows:
In the present application, the first anode 131, the second anode 151 and the reflective layer 170 are all polygonal structures, when the display panel 100 is in normal display, the first light emitting layer 133 located in the display area 110 directly emits a part of light to the display area 110, and another part of light with a positive viewing angle is reflected to the display area 110 through the first anode 131, whereas in the conventional first anode 131 structure, the oblique viewing angle light irradiated to the first anode 131 cannot compensate brightness for the edge of the pixel, and the structure of the first anode 131 is configured as a polygonal structure, for example, may be a triangle structure, and when the oblique viewing angle light reaches the first anode 131, the light is reflected through the side surface of the first anode 131, and the first anode 131 can change the light direction of a part of the oblique viewing angle incident light and irradiate towards the peep-proof area 120, and pointedly compensate the edge brightness of the peep-proof sub-pixel 150, thereby improving the brightness uniformity of the display area 110.
Meanwhile, in the conventional structure, some light reflected by the first anode 131 is absorbed by the light shielding layer 160, so that the light utilization rate is reduced.
The application improves the light utilization rate of the peep-proof sub-pixel 150 by matching the reflecting layer 170 and the second anode 151, and simultaneously compensates the light of the oblique viewing angle by reflecting the light of the first anode 131, so as to further improve the light utilization rate of the peep-proof sub-pixel 150, and meanwhile, the first anode 131 of the display area 110 can compensate the light emitted downwards by the first light emitting layer 133 to the brightness of the edge position of the pixel, so as to improve the brightness uniformity of the display area 110, reuse the light absorbed by the shading layer 160 and further improve the brightness in the peep-proof mode, and the method of improving the brightness uniformity of the panel display and compensating the peep-proof brightness in the peep-proof mode by matching the reflecting layer 170 structure and the anode layer structure can further improve the display effect, the product competition capability and reach or exceed the satisfaction of customers of the display panel 100 at low cost.
Specifically, at least one of the second anode 151 and the reflective layer 170 has a triangular structure or a trapezoidal structure. For example, when the reflective layer 170 and the second anode 151 are both in a triangle structure, after the peep-preventing sub-pixel 150 is turned on, the light emitted by the second light emitting layer 152 in the peep-preventing sub-pixel 150 irradiates on two sides of the reflective layer 170, the two inclined sides of the reflective layer 170 reflect the light to the peep-preventing area 120 to compensate the brightness of the peep-preventing area 120, and meanwhile, the light emitted by the second light emitting layer 152 downward reflects into the peep-preventing area 120 through the two inclined sides of the second anode 151 to compensate the brightness in the peep-preventing area 120, that is, under the combined action of the light reflected by the reflective layer 170 and the light reflected by the second anode 151, the brightness of the peep-preventing area 120 is further improved to improve the peep-preventing effect.
In this process, since the two inclined sides of the reflective layer 170 are disposed corresponding to the two inclined sides of the second anode 151, a part of the light reflected by the two inclined sides of the reflective layer 170 irradiates onto the two inclined sides of the second anode 151, and the two inclined sides of the second anode 151 are adjusted in the direction of the light to be emitted to a large viewing angle range, meanwhile, the two inclined sides of the second anode 151 also emit a part of the light to the reflective layer 170, and the light is continuously reflected between the reflective layer 170 and the second anode 151, thereby sequentially improving the light utilization rate, increasing the brightness of the peep-preventing area 120, and improving the peep-preventing effect.
Further, the included angle α between one side of the reflective layer 170 and the light shielding layer 160 in the present application satisfies the relationship of 30 ° < α <75 °.
When the included angle α between the side of the reflective layer 170 and the light shielding layer 160 is greater than 75 °, the inclination of the reflective layer 170 toward the peep-proof region 120 is smaller, and when the inclination of the reflective layer 170 toward the peep-proof region 120 is smaller, the light reflected by the reflective layer 170 is further deviated toward the direction of the large viewing angle when the light irradiates the side of the reflective layer 170, so that it is difficult to enter the peep-proof region 120 for brightness compensation, when the included angle α between the side of the reflective layer 170 and the light shielding layer 160 is close to 90 °, the light irradiated onto the reflective layer 170 is emitted in a stray light form, which affects the display effect, and when the included angle α between the side of the reflective layer 170 and the light shielding layer 160 is smaller than 30 °, the light exceeds the peep-proof region 120 of the large viewing angle when the light irradiates the inclined surface of the reflective layer 170, resulting in an undesirable brightness compensation effect on the peep-proof region 120.
Therefore, the present application sets the angle range of the included angle α between the side edge of the reflective layer 170 and the light shielding layer 160 to be between 30 ° and 75 °, so that the light beam, when illuminating the reflective layer 170, performs brightness compensation on the peep-proof region 120 through the reflective layer 170, and does not affect the display effect.
In the present application, the light reflected by the reflecting layer 170 is reflected by the second anode 151, and the light irradiated by the second light emitting layer 152 is reflected to enter the peep-proof region 120, so as to compensate the light of the narrow viewing angle of the peep-proof region 120, and improve the brightness from the narrow viewing angle of the peep-proof region 120, so that the reflected light of the second anode 151 can better compensate the brightness of the narrow viewing angle of the peep-proof region 120, the present application is designed for the second anode 151, and specifically comprises the following steps:
The included angle β between one side of the second anode 151 and the pixel defining layer 132 in the peep-proof region 120 satisfies the relationship of 0 ° < β <60 °.
When the angle β between one side of the second anode 151 and the pixel defining layer 132 is greater than 60 °, the light reflected from the reflective layer 170 toward the second anode 151, or the light emitted from the second light emitting layer 152 downward toward the second anode 151 is reflected by the second anode 151, one light with a wide viewing angle range of the peep-preventing area 120 is reflected, and when the angle β between one side of the second anode 151 and the pixel defining layer 132 is greater, the light reflected by the reflective layer 170 is reflected downward more easily by the second anode 151 than by entering the peep-preventing area 120, so that the peep-preventing effect is not improved, and the light interference may be caused, and the display effect is affected.
Therefore, the application limits the angle range of the included angle beta between one side of the second anode 151 and the pixel definition layer 132 in the peep-proof area 120 to be between 0 and 60 degrees, so that the second anode 151 can better compensate the light of the narrow view angle of the peep-proof area 120 and can not influence the normal display effect, thus being beneficial to compensating the light of the large view angle of the peep-proof area 120 by the light reflected by the reflecting layer 170, compensating the light of the narrow view angle of the peep-proof area 120 by the light reflected by the second anode 151, realizing the light compensation of the whole peep-proof area 120 by the processing of the light by the reflecting layer 170 and the second anode 151, and improving the brightness of the peep-proof area 120 and the peep-proof effect.

The difference between this embodiment and the embodiment shown in fig. 1 is that, in this embodiment, the reflective layer 170 is in a right trapezoid structure, the second anode 151 is in a right triangle structure, and the long inclined plane of the reflective layer 170 in the right trapezoid structure faces the display area 110, so that the light reflected by the long inclined plane of the reflective layer 170 can be irradiated into the display area 110 to compensate the brightness of the display area 110, while the long inclined plane of the second anode 151 in the right triangle structure faces the peep-proof area 120, so that when the light irradiates onto the long inclined plane of the second anode 151, the second anode 151 can reflect most of the light to the peep-proof area 120 to compensate the brightness of the peep-proof area 120.
In fig. 4, a represents a light beam emitted from the second generation layer, irradiated to the second anode, reflected by the second anode to the inclined surface of the reflection layer, B represents a light beam reflected between the reflection layer and the second anode, and C represents a light beam directly reflected by the inclined surface of the second anode.
The specific principle is that when the display panel 100 is in the peep-proof mode, a part of the light of the second light emitting layer 152 in the peep-proof sub-pixel 150 irradiates upwards to the reflecting layer 170, and because the reflecting layer 170 is in a right trapezoid structure, a part of the light irradiated to the reflecting layer 170 irradiates on the upper bottom of the reflecting layer 170, a part of the light irradiated on the inclined plane of the reflecting layer 170 reflects towards the second anode 151 again, the light continuously reflects between the second anode 151 and the reflecting layer 170 and enters the peep-proof region 120, the brightness of the peep-proof region 120 is compensated, and thus the peep-proof effect is improved, and the light irradiated to the inclined plane of the reflecting layer 170 reflects towards the display region 110, so that the brightness of the display panel 100 in the peep-proof mode in the display region 110 is increased.
Meanwhile, a part of light irradiates the second anode 151 downward from the second light emitting layer 152, and since the second anode 151 is right triangle, the inclined surface of the second anode 151 faces the peep-proof area 120, and the light irradiates the inclined surface of the second anode 151, the light irradiates the second anode 151 to reflect to the peep-proof area 120 through the second anode 151, and then the brightness of the peep-proof area 120 is compensated, so that the peep-proof effect is further improved.

When the right-angle side of the first anode 131 is different from the right-angle side of the second anode 151, the inclined plane of the first anode 131 faces the display area 110, and when the light irradiates the first anode 131, the first anode 131 reflects most of the light back to the display area 110, so as to compensate the brightness of the display area 110 and improve the display effect of the display area 110.
When the right-angle side of the first anode 131 is on the same side as the right-angle side of the second anode 151, the inclined plane of the first anode 131 faces the peep-proof region 120, and when light irradiates the first anode 131, the first anode 131 reflects light of a positive viewing angle back to the display region 110 to compensate the brightness of the display region 110, and reflects light of an oblique viewing angle to the peep-proof region 120 to compensate the brightness of the peep-proof region 120, so that the peep-proof effect and the normal display effect are improved simultaneously.
In fig. 6, a indicates light emitted from the first light emitting layer upward into the display area, B indicates light emitted from the first light emitting layer downward into the first anode, and light reflected from the first anode to the inclined surface of the reflective layer and then emitted, C indicates light reflected between the reflective layer and the second anode, and C1 indicates light emitted directly from the second anode into the peep-preventing area.

In the peep-proof display device 10, the brightness of the peep-proof area 120 of the display panel 100 in the peep-proof mode is low, which results in unsatisfactory peep-proof effect and affects the user experience.
Based on the above problems, the application improves the display panel 100 in the display device 10 by arranging the reflecting layer 170 at the position of the shading layer 160 above the peep-preventing sub-pixel 150 in the peep-preventing area 120 of the display panel 100, so that the reflecting layer 170 is positioned below the shading layer 160 and corresponds to the second anode 151 in the peep-preventing sub-pixel 150, when the peep-preventing sub-pixel 150 is turned on, the light emitted by the second light emitting layer 152 in the peep-preventing sub-pixel 150 is emitted to the reflecting layer 170, the reflecting layer 170 reflects the light to the peep-preventing wide viewing angle range for peep-preventing brightness compensation, and meanwhile, the light emitted downwards by the second light emitting layer 152 is reflected to the peep-preventing wide viewing angle range for peep-preventing brightness compensation through the second anode 151, in the process, part of the light emitted by the reflecting layer 170 is emitted to the second anode 151 after the direction adjustment of the light, and then is emitted to the large viewing angle range and the reflecting layer 170, and meanwhile, part of the light emitted by the second anode 151 is also emitted to the reflecting layer 170 after the direction adjustment, the second anode 151 is emitted to the large viewing angle range, and the light can enter the peep-preventing brightness compensation area through the reflecting layer 151, and the peep-preventing brightness can be further improved, and the display device 120 can be further improved.
It should be noted that, the inventive concept of the present application can form a very large number of embodiments, but the application documents are limited in space and cannot be listed one by one, so that on the premise of no conflict, the above-described embodiments or technical features can be arbitrarily combined to form new embodiments, and after the embodiments or technical features are combined, the original technical effects will be enhanced.
The above description of the application in connection with specific alternative embodiments is further detailed and it is not intended that the application be limited to the specific embodiments disclosed. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the application, and these should be considered to be within the scope of the application.
