Detailed Description
Refer to the drawings wherein like reference numbers refer to like elements throughout. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a display panel according to a first embodiment of the present application. The first embodiment of the present application provides a display panel 100, which includes a substrate 11, a thin-film transistor layer 12, an organic light-emitting pixel layer 13, a cathode 14, a reflective layer 15, an encapsulation layer 16, a polarizer 17, a touch layer 18, an optical adhesive 19, and a cover plate 10. The reflective layer 15 is disposed between the cathode 14 and the polarizer 17, and serves to reflect light of a specific wavelength.
In the first embodiment, the thin-film-transistor layer 12 is disposed on the substrate 11. An organic light-emitting pixel layer 13 is disposed on the thin-film transistor layer 12. The cathode 14 is disposed on the organic light emitting pixel layer 13. A reflective layer 15 is disposed on the cathode 14. An encapsulation layer 16 is disposed on the reflective layer 15. A polarizer 17 is disposed on the encapsulation layer 16. The touch layer 18 is disposed on the polarizer 17. The optical adhesive 19 is disposed on the touch layer 18. The cover plate 10 is disposed on the optical cement 19.
The organic light emitting pixel layer 13 includes a plurality of sub-pixels. The sub-pixels have a spacer a therebetween. The reflective layer 15 includes a plurality of reflective units 151. The reflection unit 151 is disposed corresponding to the spacer a.
In the display panel 100 of the first embodiment, the light with a specific wavelength is reflected by the reflection unit 151 in the reflection layer 15, so as to reduce the brightness of the light. That is, the provision of the reflection unit 151 functions to reduce the outgoing luminance of the reflected light. For example, the reflection unit 151 reflects red light, a portion of red light emitted from the red sub-pixel 131 radiated to the reflection unit 151 is reflected back to one side of the organic light emitting pixel layer 13, and red light not radiated to the reflection unit 151 is transmitted through the polarizer 17 and emitted, wherein the luminance of red light emitted from the red sub-pixel 131 is reduced with respect to the display panel 100. Note that the light-out luminance is the luminance after the light passes through the polarizer 17.
In the display panel 100 of the first embodiment, the plurality of sub-pixels includes a red sub-pixel 131, a green sub-pixel 132, and a blue sub-pixel 133. The light reflected by the reflective layer 15 is emitted from the red sub-pixel 131 and the green sub-pixel 132.
In the prior art, the brightness of the light emitted by the red sub-pixel and the green sub-pixel transmitted through the polarizer is greater than that of the light emitted by the blue sub-pixel transmitted through the polarizer. Therefore, in the first embodiment of the present application, the reflection unit 151 is arranged to reflect a portion of the light emitted by the red sub-pixel 131 and a portion of the light emitted by the green sub-pixel 132, so as to achieve the effects of reducing the red light brightness and filtering the light brightness, and the light emitted by the blue sub-pixel 133 can pass through the reflection unit 151, so that the brightness of the red light, the green light, and the blue light tends to be balanced.
The reflection unit 151 may be configured to reflect light of a certain wavelength band of red and light of a certain wavelength band of green, and may also be configured to reflect light of all wavelengths of red and green. How the specific reflection unit 151 is disposed may be determined according to actual situations.
Specifically, referring to fig. 2, fig. 2 is a schematic structural diagram of a reflection unit of a display panel according to a first embodiment of the present application. The reflection unit 151 includes at least three sublayers 152. At least three sublayers 152 are stacked to form at least two interface reflection surfaces 15 a. The at least three sub-layers 152 are formed by alternately stacking sub-layers with high refractive index and sub-layers with low refractive index.
At least one boundary reflective surface 15a reflects the light emitted from the red sub-pixel 131. At least one boundary reflective surface 15a reflects the light emitted from the green sub-pixel 132.
That is, one reflection unit 151 may be used to reflect at least two colors of light at the same time. The reflectivity of the reflective unit 151 for a specific light can be adjusted by adjusting the refractive index and thickness of the sub-layer. For example, the high refractive index material may be an inorganic material such as niobium pentoxide, and the low refractive index material may be an inorganic material such as silicon dioxide.
In the first embodiment, the number of the sub-layers 152 of the reflective unit 151 is three, but the invention is not limited thereto.
In the display panel 100 of the first embodiment, the reflective layer 15 further includes a light-transmitting unit 153 disposed in the same layer as the reflective unit 151. The light-transmitting unit 153 is filled with a light-transmitting material to facilitate light penetration.
In addition, the orthographic projection of the reflection unit 151 on the plane of the spacer a is located in the spacer a adjacent to the blue sub-pixel 133. That is, the reflection unit 151 is disposed directly above the spacer a adjacent to the blue subpixel 133. That is, the reflection unit 151 is disposed between the blue subpixel 133 and the red subpixel 131, and between the blue subpixel 133 and the green subpixel 132. With this arrangement, the reflection unit 151 reflects a small portion of red and green light, facilitating fine adjustment of the light emission of the red and green light.
In the first embodiment, when the display panel 100 emits light, the light emitted from the blue sub-pixel 133 in the organic light emitting pixel layer 13 directly transmits through the reflective unit 151 and the light transmitting unit 153 of the reflective layer 15, and the blue light is transmitted from the polarizer 17. Most of the red light emitted from the red sub-pixel 131 of the organic light emitting pixel layer 13 transmits through the light transmitting unit 153 of the reflective layer 15 and transmits the red light from the polarizer 17, and a small portion of the red light is radiated to the reflective unit 151 and reflected back to the light emitting side. Most of the green light emitted from the green sub-pixel 132 of the organic light emitting pixel layer 13 is transmitted through the light transmitting unit 153 of the reflective layer 15 and is transmitted out of the green light from the polarizer 17, and a small portion of the green light is radiated to the reflective unit 151 to be reflected back to the light emitting side. Thus, the brightness of the red light and the green light is weakened, and the blue light is unchanged, so that the effect of balancing the three colors of light is achieved.

In the display panel 200 of the second embodiment, the display panel 200 includes a substrate 21, a thin-film transistor layer 22, an organic light-emitting pixel layer 23, a cathode 24, a reflective layer 25, an encapsulation layer 26, a polarizer 27, a touch layer 28, an optical adhesive 29, and a cover plate 20. The reflective layer 25 is disposed between the cathode 24 and the polarizer 27, and serves to reflect light of a specific wavelength.
The reflective layer 25 includes a plurality of reflective units 251. The organic light emitting pixel layer 23 includes red, green and blue sub-pixels 231, 232 and 233.
The second embodiment is different from the first embodiment in that: the orthographic projection of the reflecting unit 251 on the plane of the spacer a is located in the spacer a between the red subpixel 231 and the green subpixel 232. I.e., the reflection unit 251 is disposed between the red subpixel 231 and the green subpixel 232. With this arrangement, the reflection unit 251 reflects a small portion of the red and green lights, facilitating fine adjustment of the light emission of the red and green lights.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a display panel according to a third embodiment of the present application. In the display panel 300 of the third embodiment, the display panel 300 includes a substrate 31, a thin-film transistor layer 32, an organic light-emitting pixel layer 33, a cathode 34, a reflective layer 35, an encapsulation layer 36, a polarizer 37, a touch layer 38, an optical adhesive 39, and a cover plate 30. The reflective layer 35 is disposed between the cathode 34 and the polarizer 37, and serves to reflect light of a specific wavelength.
The reflective layer 35 includes a plurality of reflective units 351. The organic light emitting pixel layer 33 includes a plurality of sub-pixels, such as a red sub-pixel 331, a green sub-pixel 332, and a blue sub-pixel 333.
The third embodiment is different from the first embodiment in that: the reflective units 351 are disposed in one-to-one correspondence with the spacers a. The orthogonal projection of the reflection unit 351 on the plane of the spacer a is located in the spacer a. That is, the reflective units 351 are disposed between two adjacent sub-pixels in a one-to-one correspondence. With this arrangement, the reflection unit 351 reflects a larger portion of the red light and the green light, thereby facilitating a larger adjustment of the light emission of the red light and the green light.
