FIG. 1 is a structural schematic diagram of a display substrate according to an embodiment of the present disclosure. - As shown in
FIG. 1 , thedisplay substrate 10 may include: a substrate 11, and a plurality ofpolygonal pixels 121 arranged in an array on the substrate 11. Eachpolygonal pixel 121 includes a plurality ofsub-pixels 1211 and aphotoelectric sensor 1212. An orthographic projection of the plurality ofsub-pixels 1211 on the substrate 11 and an orthogonal projection of thephotoelectric sensor 1212 on the substrate 11 do not overlap with each other. - As shown in
FIG. 1 , the plurality ofpolygonal pixels 121 form an array 12 for performing display and/or fingerprint detection. - In some embodiments, in each
polygonal pixel 121, the plurality ofsub-pixels 1211 are disposed on the periphery of thepolygonal pixel 121, and an edge of eachsub-pixel 1211 at a periphery of thepolygonal pixels 121 overlaps with an edge of thepolygonal pixel 121. - In some embodiments, as shown in
FIG. 2 andFIG. 3 , a shape of thesub-pixel 1211 is a triangle or an isosceles trapezoid. - In some embodiments, as shown in
FIG. 4 , in eachpolygonal pixel 121, an edge of eachsub-pixel 1211 near the center of thepolygonal pixel 121 has an arc shape, and an arcing direction of the arc shape departs from the center of thepolygonal pixel 121. - In some embodiments, each
polygonal pixel 121 includes threesub-pixels 1211 of different colors (e.g. RGB), and a shape of thepolygonal pixel 121 is a hexagon. - As shown in
FIG. 2 , the threesub-pixels 1211 of different colors in eachpolygonal pixel 121 correspond to thefirst edge 001, thethird edge 002, and thefifth edge 003 of the hexagon respectively. - In some embodiments, as shown in
FIG. 6 , eachpolygonal pixel 121 includes foursub-pixels 1211 of different colors (e.g. RGBW), and a shape of thepolygonal pixels 121 is an octagon. - In some embodiments, as shown in
FIG. 6 , the foursub-pixels 1211 of different colors in eachpolygonal pixel 121 correspond to the first edge, the third edge, the fifth edge and the seventh edge of the octagon respectively. - The
polygonal pixel 121 with a hexagonal shape will be described as an example below. - In an embodiment of the present disclosure, the
sub-pixel 1211 may have a triangular shape. Thepolygonal pixel 121 composed ofsuch sub-pixels 1211 is shown inFIG. 2 . The red sub-pixel corresponds to theedge 001 at the upper left corner of the hexagon, the green sub-pixel corresponds to theedge 002 at the upper right corner of the hexagon, and the blue sub-pixel corresponds to theedge 003 at the bottom of the hexagon. In this case, thephotoelectric sensor 1212 includes three regions which are unconnected with each other (i.e., three isolated regions). For example, each region may correspond to onephotoelectric sensor 1212, resulting in higher resolution. It should be understood that the arrangement of the sub-pixels is not limited to the manner shown inFIG. 2 . For example, the red sub-pixel may correspond to the edge at the top of the hexagon, the green sub-pixel may correspond to the edge at lower left corner of the hexagon, and the blue sub-pixel may correspond to the lower right corner of the hexagon.FIG. 2 is just one of many arrangements. - In another embodiment of the present disclosure, the
sub-pixel 1211 may have an isosceles trapezoid shape. Thepolygonal pixels 121 composed ofsuch sub-pixels 1211 is shown inFIG. 3 . In this case, the three regions corresponding to thephotoelectric sensor 1212 connect with each other. That is, onepolygonal pixel 121 corresponds to onephotoelectric sensor 1212. - In some embodiments, as shown in
FIG. 4 , in eachpolygonal pixel 121, an edge of eachsub-pixel 1211 near the center of thepolygonal pixel 121 has an arc shape, and an arcing direction of the arc shape departs from the center of thepolygonal pixel 121. Thepolygonal pixels 121 composed ofsuch sub-pixels 1211 can be as shown inFIG. 4 . In this case, the three regions corresponding to thephotoelectric sensor 1212 connect with each other. That is, onepolygonal pixel 121 corresponds to onephotoelectric sensor 1212. - In addition, in order to prevent the light emitted by the sub-pixel 1211 from affecting the
photoelectric sensor 1212, in an embodiment of the present disclosure, thephotoelectric sensor 1212 and the plurality of sub-pixels 1211 are disposed in different layers, and the plurality of sub-pixels 1211 are closer to the light exit side (i.e. the side on which the reflector 5 is located inFIG. 5 ) of thedisplay substrate 10 than thephotoelectric sensor 1212. As shown inFIG. 5 , the light emitted by the sub-pixel 1211 is reflected by the reflector 5, and the reflected light is received by thephotoelectric sensor 1212. Since thephotoelectric sensor 1212 is lower than the sub-pixel 1211, thephotoelectric sensor 1212 does not directly receive the light emitted by the sub-pixel 1211, so that the light emitted by the sub-pixel 1211 does not affect thephotoelectric sensor 1212. - In some embodiments, the
photoelectric sensor 1212 is a photodiode. Those skilled in the art can understand that the photoelectric sensor can also be a photomultiplier tube, a photoresistor, a phototransistor, a photocell, a semiconductor color sensor, a pyroelectric sensor, an optoelectronic coupler, and the like. - In some embodiments, as shown in
FIG. 5 , the sub-pixel 1211 is a light emitting device. For example, the sub-pixel 1211 may be an OLED. Those skilled in the art can understand that the sub-pixel 1211 may also be a transparent device (e.g. a liquid crystal cell or a filter). As shown inFIG. 5 , in this case, light from below the substrate 11 can pass through the sub-pixel 1211 and be reflected by the reflector 5 to thephotoelectric sensor 1212. The sub-pixel 1211 can be a filter, and thedisplay substrate 10 can thus be a color film substrate in a liquid crystal display device. - In the display substrate according to the embodiment of the present disclosure, a plurality of sub-pixels and photoelectric sensor are arranged in a polygonal pixel, and a plurality of polygonal pixels form an array, which can maximize the collection of light signals, thereby improving the efficiency of the photoelectric sensor and the accuracy of fingerprint identification.
- The present disclosure also provides a display panel including the display substrate described in the above embodiments.
- The present disclosure further provides a display device including the display panel described in the above embodiment. The display device may be a display screen of a mobile terminal, a tablet computer, or the like. Based on the display device, an embedded fingerprint identification method can be implemented. Specifically, when the display device is displaying, the display device emits light. The user can press a finger on the display device, and the display device can receive the light reflected by the user's finger. After receiving the reflected light, the photodiode in the display device can send the light intensity information to the processor, and the processor generates a fingerprint image. Then the fingerprint image is compared with the fingerprint template pre-recorded in the fingerprint library to identify the fingerprint. With this display device, the accuracy of embedded fingerprint identification can be effectively improved.
