The present invention provides display panels including, but not limited to, the following embodiments.
In one embodiment, as shown in fig. 1, the display panel 00 includes a thin film transistor layer 100, the thin film transistor layer 100 includes a source/drain electrode, wherein the source/drain electrode includes a source electrode 101 and a drain electrode 102, and the display panel 00 further includes: the reflecting layer 200 is arranged on the same layer as the source drain 101, the reflecting layer 200 and the source drain are formed at one time, and the reflecting layer 200 is used for reflecting external light.
The display panel 00 further includes a substrate 300, where a constituent material of the substrate 300 may be glass, and the substrate 300 is used for carrying the thin film transistor layer 100 and other related film layers.
The thin film transistor layer 100 further includes a gate electrode 103, a gate insulating layer 104, and an active layer 105, and it is understood that the thin film transistor layer 100 may be a bottom gate structure or a top gate structure, and the bottom gate structure is taken as an example for illustration in this embodiment. Specifically, the gate 103 is disposed on the substrate 300, the gate insulating layer 104 is disposed on the gate 103 and the substrate 300, the active layer 105 is disposed on the gate insulating layer 104, the source and the drain are disposed on the active layer 105, the source 101 and the drain 102 are respectively disposed at two ends of the active layer 105, and the source 101 and the drain 102 are respectively electrically connected with the active layer 105.
In particular, the reflective layer 200 is disposed on the gate insulating layer 104. It will be appreciated that the active layer 105 does not completely cover the gate insulating layer 104, i.e., the first target region 01 not covered by the active layer 105 is further included on the gate insulating layer 104, the source electrode 101 and the drain electrode 102 may be formed on the active layer 105 after the active layer 105 is formed, and the reflective layer 200, i.e., the source electrode 101, the drain electrode 102, and the reflective layer 200 may be simultaneously and once formed in the first target region 01 on the gate insulating layer 104. Thus, not only can the process be simplified, but also the thickness of the display panel 00 can be reduced, which is advantageous for the light and thin display panel 00.
The drain electrode 102 may be adjacent to the reflective layer 200 in the source-drain electrode, and the drain electrode 102 may be connected to the reflective layer 200, or the drain electrode 102 may be spaced from the reflective layer 200. It may be appreciated that, when the reflective layer 200 is disposed in connection with the drain electrode 102, the reflective layer 200 is electrically connected with the drain electrode 102, and the reflective layer 200 may be used as a pixel electrode corresponding to the source and drain electrodes, and when attention needs to be paid, the light transmittance requirement of the reflective layer 200 should be ensured, so that light emitted by the backlight source may pass through the reflective layer 200. In this way, the pixel electrode can be prevented from being separately prepared, the thickness of the display panel 00 can be further reduced, and the light and thin display panel 00 is facilitated.
It is understood that the constituent materials of the source electrode 101, the drain electrode 102 and the reflective layer 200 are the same, and further, the constituent materials of the source electrode 101, the drain electrode 102 and the reflective layer 200 may include metals, for example, the constituent materials of the source electrode 101, the drain electrode 102 and the reflective layer 200 may include, but are not limited to, silver, aluminum.
In one embodiment, as shown in fig. 2, the reflective layer 200 includes a plurality of reflective parts 201, and the display panel 00 further includes: and a plurality of protrusions 400 provided on a side of the light-emitting surface 04 remote from the reflection layer 200, the plurality of reflection parts 201 being provided opposite to the plurality of protrusions 400, each of the plurality of reflection parts 201 having the same shape as the corresponding protrusion 400.
It is understood that, since the plurality of protrusions 400 are disposed on the side away from the light emitting surface 04 of the reflective layer 200, and the surface of the plurality of protrusions 400 on the side close to the reflective layer 200 is in a rugged shape, if a film layer is uniformly formed on the surface of the plurality of protrusions 400 on the side close to the reflective layer 200, the film layer may also have the same shape as the plurality of protrusions 400. Similarly, when the reflective layer 200 is fabricated, the shape of each reflective portion 201 of the plurality of reflective portions 201 is the same as the shape of the corresponding protrusion 400, that is, the shape of the light-emitting surface 04 of the reflective layer 200 is also identical to the shape of the plurality of protrusions 400. Therefore, the plurality of protrusions 400 may make the light emitting surface 04 of the reflective layer 200 have a rugged shape, so that external light may be diffusely reflected on the light emitting surface 04 of the reflective layer 200, and the reflection direction of the external light may be increased, so as to increase the uniformity of the display screen of the display panel 00 and increase the visual angle of the display screen of the display panel 00.
In one embodiment, as shown in fig. 2, the plurality of protrusions 400 and the gate electrode 103 are disposed in the same layer. Further, the plurality of protrusions 400 and the gate electrode 103 are formed at one time. It is understood that the gate electrode 103 does not entirely cover the substrate 300, i.e., the substrate 300 further includes a second target region 02 uncovered by the gate electrode 103, the gate electrode 103 may be formed on the non-second target region 02 in the substrate 300, and the plurality of protrusions 400 may be formed on the second target region 02 in the substrate 300, i.e., the gate electrode 103 and the plurality of protrusions 400 may be simultaneously and once formed. Thus, not only the thickness of the display panel 00 can be reduced, which is advantageous for the light and thin of the display panel 00, but also the process can be simplified.
Similarly, the constituent materials of the plurality of protrusions 400 and the gate electrode 103 may be the same, further, the constituent materials of the plurality of protrusions 400 and the gate electrode 103 may include metals, and the constituent materials of the plurality of protrusions 400 and the gate electrode 103 may include, but are not limited to, copper, aluminum, molybdenum, titanium.
In one embodiment, as shown in fig. 3-5, the plurality of protrusions 400 are identical in shape or the plurality of protrusions 400 are different in shape. Further, the plurality of protrusions 400 have a shape of a cylinder or a prism. Specifically, as shown in fig. 3-5, the gate electrode 103 in the thin film transistor layer 100 is electrically connected to the gate line 05, the source electrode 101 in the thin film transistor layer 100 is electrically connected to the data line 06, the drain electrode 102 in the thin film transistor layer 100 may be electrically connected to the pixel electrode 500, and as described above, the pixel electrode 500 may be used as the reflective layer 200, that is, the pixel electrode 500 may realize a light transmission function and a light reflection function.
Specifically, as shown in fig. 3, for example, projections of the plurality of protrusions 400 on the bottom surface of the display panel 00 may be all circular, for example, part of the protrusions 400 in the plurality of protrusions 400 may be cylindrical, part of the protrusions 400 may be truncated cones, and part of the protrusions 400 may be hemispheres; as shown in fig. 4, the projections of the plurality of protrusions 400 on the bottom surface of the display panel 00 may be rectangular, for example, some of the plurality of protrusions 400 may be rectangular, and some of the protrusions 400 may be prismatic tables with rectangular top surfaces; as another example, as shown in fig. 5, the projection of the plurality of protrusions 400 on the bottom surface of the display panel 00 may be rectangular, circular, triangular, diamond-shaped, or other shapes, for example, part of the protrusions 400 in the plurality of protrusions 400 may be a cylinder, part of the protrusions 400 may be a truncated cone, part of the protrusions 400 may be a hemisphere, part of the protrusions 400 may be a prism, and part of the protrusions 400 may be a truncated pyramid.
In one embodiment, as shown in fig. 6, the display panel 00 further includes: and a protection layer 600, wherein the protection layer 600 is disposed on one side close to the light emitting surface 04 of the reflection layer 200, and the protection layer 600 is used for protecting the reflection layer 200. It can be appreciated that the reflective layer 200 is disposed on the light-emitting surface 04 of the reflective layer 200, so that the reflective layer 200 is prevented from being oxidized or corroded by external moisture. Further, taking the case where the reflective layer 200 is connected to the source/drain electrode, the protective layer 600 may be further disposed on a side of the source electrode 101, the drain electrode 102, the active layer 105, and the gate insulating layer 104, which is far away from the substrate 300, to prevent oxidation or corrosion of the source/drain electrode, the active layer 105, and the gate insulating layer 104 by external moisture.
In an embodiment, as shown in fig. 7, the protective layer 600 includes at least one first protective layer 601 and at least one second protective layer 602, the at least one first protective layer 601 and the at least one second protective layer 602 are stacked, and refractive indexes of the at least one first protective layer 601 and the at least one second protective layer 602 are different. The specific refractive indexes of the at least one first protective layer 601 and the at least one second protective layer 602 are not limited, so long as the difference between the refractive indexes is ensured; the thickness of the first protective layer 601 and the second protective layer 602 may be not less than 50 nm and less than 100 nm. Further, taking the example that the second protection layer 602 is disposed on the first protection layer 601, the refractive index of the first protection layer 601 may be greater than the refractive index of the second protection layer 602.
In an embodiment, as shown in fig. 8, when the protective layer 600 includes a plurality of first protective layers 601 and a plurality of second protective layers 602, the plurality of first protective layers 601 and the plurality of second protective layers 602 are alternately and stacked. In particular, the protective layer 600 may also be configured to include two first protective layers 601 and one second protective layer 602, and the one second protective layer 602 is disposed between the two first protective layers 601, wherein the refractive index of the first protective layer 601 may be greater than the refractive index of the second protective layer 602. Further, the number of the plurality of first protective layers 601 in the protective layer 600 may be one more than the number of the plurality of second protective layers 602 in the protective layer 600, and the plurality of first protective layers 601 and the plurality of second protective layers 602 may be alternately and stacked.
It will be appreciated that the protective layer 600 includes the first protective layer 601 and the second protective layer 602 with different refractive indexes, and the first protective layer 601 and the second protective layer 602 are alternately stacked together periodically, so that the protective layer 600 forms a distributed bragg reflector. Specifically, the light is reflected by the first protective layer 601 and the second protective layer 602, and the overall reflectivity of the protective layer 600 is related to the refractive index of the first protective layer 601 and the refractive index of the second protective layer 602, when the light passes through the first protective layer 601 and the second protective layer 602 with different refractive indexes, the light reflected by the first protective layer 601 and the second protective layer 602 interferes constructively due to the change of the phase angle, and then the light is combined with each other to obtain strong reflected light, that is, the external light can reflect more light after passing through the protective layer 600, so that the brightness of the display screen displayed by the display panel 00 is improved.
Further, the thicknesses of the first protective layer 601 and the second protective layer 602 are different. It can be understood that, for the single-layer film, the external light includes light with multiple colors, assuming that the wavelength of the light a in the external light is λ, and half-wave loss exists in the light a entering the single-layer film, according to the optical path difference principle, the reflection peak of the light a occurs when the thickness of the single-layer film is odd multiple of (λ/4), and the reflection peak of the light a is more sensitive to the film thickness, that is, the single-layer film with the thickness of odd multiple of (λ/4) is strongest to the reflection light of the light a. Further, in this embodiment, the thicknesses of any two of the first protective layers 601 may be different, the thicknesses of any two of the second protective layers 602 may be different, and the thicknesses of any two of the first protective layers 601 and the second protective layers 602 may be different, so that the film thicknesses of each layer of the protective layers 600 may be different, and the selectivity of the reflection peak value of the light with any color to the single film with a specific film thickness may be weakened; it may be understood that when the number of the film thickness in the protective layer 600 is more, the light with more colors can obtain the corresponding reflection peak value, so that only light with one color can obtain the corresponding reflection peak value, the amounts of the reflection light corresponding to the light with different colors are equivalent, and color shift of the display screen displayed by the display panel 00 is relieved.
The number of the first protective layer 601 and the second protective layer 602, and the thickness of the first protective layer 601 and the second protective layer 602 may be set according to the color cast of the display screen of the display panel 00.
In an embodiment, the constituent material of the first protection layer 601 includes silicon nitride, and the constituent material of the second protection layer 602 includes silicon oxide. It can be understood that the silicon nitride and the silicon oxide are both insulating materials, have stable chemical properties, can protect the source and drain electrodes and the reflective layer 200, and have different refractive indexes, so that the brightness of the display picture of the display panel 00 is improved, and the color cast of the display picture of the display panel 00 is relieved.
