The present invention provides a display panel including, but not limited to, the following embodiments.
In an 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 and a drain, where the source and the drain include a source 101 and a drain 102, and the display panel 00 further includes: the reflective layer 200, the reflective layer 200 and the source and drain 101 are arranged on the same layer, the reflective layer 200 and the source and drain are formed in one step, and the reflective layer 200 is used for reflecting external light.
The display panel 00 further includes a substrate 300, the substrate 300 may be made of glass, and the substrate 300 is used to support the thin-film transistor layer 100 and other related film layers.
The thin-film transistor layer 100 further includes a gate 103, a gate insulating layer 104, and an active layer 105, and it can be 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 description 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 drain electrodes 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 to the active layer 105.
In particular, the reflective layer 200 is disposed on the gate insulating layer 104. It is understood that the active layer 105 does not completely cover the gate insulating layer 104, i.e., the gate insulating layer 104 further includes a first target region 01 not covered by the active layer 105, after the active layer 105 is formed, the source electrode 101 and the drain electrode 102 may be formed on the active layer 105, and the reflective layer 200 may be formed in the first target region 01 on the gate insulating layer 104, i.e., the source electrode 101, the drain electrode 102 and the reflective layer 200 may be formed at the same time and in one step. Thus, the process can be simplified, the thickness of the display panel 00 can be reduced, and the display panel 00 can be thinned.
Among the source and drain electrodes, the drain electrode 102 may be located near the reflective layer 200, 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 can be understood that, when the reflective layer 200 and the drain electrode 102 are connected, the reflective layer 200 and the drain electrode 102 are electrically connected, and at this time, 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 can pass through the reflective layer 200. Thus, the separate preparation of the pixel electrode can be avoided, the thickness of the display panel 00 can be further reduced, and the thinning of the 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 metal, 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 and aluminum.
In an embodiment, as shown in fig. 2, the reflective layer 200 includes a plurality of reflective portions 201, and the display panel 00 further includes: a plurality of protrusions 400, the plurality of protrusions 400 being disposed on a side away from the light emitting surface 04 of the reflective layer 200, the plurality of reflective portions 201 being disposed opposite to the plurality of protrusions 400, and a shape of each of the plurality of reflective portions 201 being the same as a shape of 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 has a rugged shape, if a film layer is uniformly formed on the surface of the 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 manufactured, the shape of each of the reflective portions 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 the same as the shape of the plurality of protrusions 400. Therefore, the plurality of protrusions 400 are disposed to make the light-emitting surface 04 of the reflective layer 200 have a rugged shape, so that external light can be diffusely reflected on the light-emitting surface 04 of the reflective layer 200, and the reflection direction of the external light can be increased to increase the uniformity of the display image of the display panel 00 and increase the visual angle of the display image of the display panel 00.
In one embodiment, as shown in fig. 2, the plurality of protrusions 400 and the gate 103 are disposed on 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 103 does not completely cover the substrate 300, i.e. the substrate 300 further includes the second target area 02 not covered by the gate 103, the gate 103 can be formed on the non-second target area 02 in the substrate 300, and the plurality of protrusions 400 can be formed on the second target area 02 in the substrate 300, i.e. the gate 103 and the plurality of protrusions 400 can be formed simultaneously and at one time. Thus, the thickness of the display panel 00 can be reduced, which is beneficial to the lightness and thinness of the display panel 00 and can simplify the process.
Similarly, the composition materials of the plurality of protrusions 400 and the gate 103 may be the same, further, the composition materials of the plurality of protrusions 400 and the gate 103 may include metal, and the composition materials of the plurality of protrusions 400 and the gate 103 may include, but are not limited to, copper, aluminum, molybdenum, and titanium.
In one embodiment, as shown in fig. 3-5, the plurality of protrusions 400 are the same shape, or the plurality of protrusions 400 are different shapes. Further, the plurality of protrusions 400 may have a cylindrical or prismatic shape. Specifically, as shown in fig. 3 to 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, and the drain electrode 102 in the thin-film transistor layer 100 is electrically connected to the pixel electrode 500, as described above, the pixel electrode 500 can be used as the reflective layer 200, that is, the pixel electrode 500 can achieve the light-transmitting function and the light-reflecting function.
Specifically, for example, as shown in fig. 3, the projections of the plurality of protrusions 400 on the bottom surface of the display panel 00 may all be circular, for example, a part of the plurality of protrusions 400 may be a cylinder, a part of the plurality of protrusions 400 may be a circular truncated cone, and a part of the plurality of protrusions 400 may be a hemisphere; for another example, as shown in fig. 4, the projections of the plurality of protrusions 400 on the bottom surface of the display panel 00 may be all rectangular, for example, some of the protrusions 400 may be rectangular parallelepipeds, and some of the protrusions 400 may be truncated pyramids with rectangular top surfaces; for another example, as shown in fig. 5, the projections of the plurality of protrusions 400 on the bottom surface of the display panel 00 may be rectangular, circular, triangular, rhombic, or other shapes, for example, some of the plurality of protrusions 400 may be cylinders, some of the plurality of protrusions 400 may be truncated cones, some of the plurality of protrusions 400 may be hemispheres, some of the plurality of protrusions 400 may be prisms, and some of the plurality of protrusions 400 may be truncated pyramids.
In an embodiment, as shown in fig. 6, the display panel 00 further includes: the protective layer 600 is disposed on a side of the light emitting surface 04 close to the reflective layer 200, and the protective layer 600 is used for protecting the reflective layer 200. It can be understood that the reflective layer 200 is disposed on the light emitting surface 04 of the reflective layer 200, so as to prevent the reflective layer 200 from being oxidized or corroded by external moisture. Further, for example, the reflective layer 200 is connected to the source and drain electrodes, and the protective layer 600 may also be disposed on a side close to the source 101, the drain 102, the active layer 105, and the gate insulating layer 104, which is far away from the substrate 300, so as to prevent the source and drain electrodes, the active layer 105, and the gate insulating layer 104 from being oxidized or corroded by external moisture.
In an embodiment, as shown in fig. 7, the protection layer 600 includes at least one first protection layer 601 and at least one second protection layer 602, the at least one first protection layer 601 and the at least one second protection layer 602 are stacked, and refractive indexes of the at least one first protection layer 601 and the at least one second protection layer 602 are different. Wherein, specific refractive indexes of the at least one first protection layer 601 and the at least one second protection layer 602 are not limited as long as a difference between the refractive indexes is ensured; the thicknesses 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 second protection layer 602 disposed on the first protection layer 601 as an example, 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 protection layer 600 may also be configured to include two first protection layers 601 and one second protection layer 602, and the one second protection layer 602 is disposed between the two first protection layers 601, wherein the refractive index of the first protection layer 601 may be greater than the refractive index of the second protection 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 are alternately and laminatedly disposed.
It is understood that the protection layer 600 includes the first protection layer 601 and the second protection layer 602 with different refractive indexes, and the first protection layer 601 and the second protection layer 602 are alternately and periodically stacked together, so that the protection layer 600 constitutes a distributed bragg reflector. Specifically, light is reflected by both the first protective layer 601 and the second protective layer 602, and the total 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 performs constructive interference due to the change of the phase angle, and then 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 of 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 of multiple colors, and assuming that the wavelength of the light a in the external light is λ, there is half-wave loss when the light a enters the single-layer film, as known from the optical path difference principle, when the thickness of the single-layer film is odd times (λ/4), a reflection peak of the light a occurs, and the reflection peak of the light a is sensitive to the film thickness, that is, the reflection light of the light a is strongest for the single-layer film with the odd times (λ/4). Further, in this embodiment, the thicknesses of any two first protection layers 601 may be different, the thicknesses of any two second protection layers 602 may be different, and the thicknesses of any two first protection layers 601 and the second protection layers 602 may be different, so that the thicknesses of the films in the protection layers 600 are different, and the selectivity of the peak value of the reflected light of any color of light to a single film with a specific film thickness may be weakened; it can also be understood that when the number of the film thicknesses in the protection layer 600 is more, the light rays with more colors can all obtain the corresponding reflected light peak value, so that it is avoided that only one light ray with one color can obtain the corresponding reflected light peak value, the amount of the reflected light corresponding to the light with different colors is equivalent, and the color cast of the display screen of the display panel 00 is alleviated.
The number of the first protective layer 601 and the second protective layer 602, and the thickness types of the first protective layer 601 and the second protective layer 602 may be set according to the color shift of the display screen of the display panel 00.
In an embodiment, a composition material of the first protection layer 601 includes silicon nitride, and a composition material of the second protection layer 602 includes silicon oxide. It can be understood that silicon nitride and silicon oxide are both insulating materials and have stable chemical properties, which can protect the source/drain and the reflective layer 200, and the refractive indexes of silicon nitride and silicon oxide are different, thereby improving the brightness of the display image of the display panel 00 and alleviating the color cast of the display image of the display panel 00.
